Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Cell Quantum Efficiency Basics Cell Quantum Efficiency Basics Photovoltaic Cell Quantum Efficiency Basics August 20, 2013 - 3:05pm Addthis Quantum efficiency (QE) is the ratio of the number of charge carriers collected by a photovoltaic (PV) cell to the number of photons-or packets of light-of a given energy shining on the solar cell. Quantum efficiency therefore relates to the response of a solar cell to the various wavelengths in the spectrum of light shining on the cell. The QE is given as a function of either wavelength or energy. If all the photons of a certain wavelength are absorbed and the resulting minority carriers (for example, electrons in a p-type material) are collected, then the QE at that particular wavelength has a value of one. The QE for photons with energy below the bandgap is zero.

FEMP originally developed Federal Water Efficiency Best Management Practices (BMPs) in response to Executive Order (E.O.) 13123 requirements, which required Federal agencies to reduce water use through cost-effective water efficiency improvements. E.O. 13423 supersedes E.O. 13123. To account for the superseded requirement changes, water use patterns, and advancing technologies, the Environmental Protection Agency's WaterSense Office updated the original BMPs.

Basics of pump-and-treat ground-water remediation technology. Special report  

SciTech Connect

The pump-and-treat process, whereby contaminated ground water is pumped to the surface for treatment, is one of the most common ground-water remediation technologies used at hazardous waste sites. However, recent research has identified complex chemical and physical interactions between contaminants and the subsurface media which may impose limitations on the extraction part of the process. The report was developed to summarize the basic considerations necessary to determine when, where, and how pump-and-treat technology can be used effectively to remediate ground-water contamination.

Treatment of sea water using electrodialysis: Current efficiency evaluation  

Science Journals Connector (OSTI)

In this paper, desalination of seawater using a laboratory scale electrodialysis (ED) cell was investigated. At steady state operation of ED, the outlet concentration of dilute stream was measured at different voltages (2?6V), flow rates (0.1?5.0mL/s) and feed concentrations (5000?30,000ppm). The electrical resistance of sea water solution in the dilute compartment was initially calculated using basic electrochemistry rules and average concentration of feed and dilute streams. Then, current intensity in each run was evaluated using Ohm's law. Finally, current efficiency (CE) which is an important parameter in determining the optimum range of applicability of an ED cell was calculated. It was found out that, at flow rates larger than 1.5mL/s, higher feed concentrations lead to larger values of CE. However, exactly opposite behavior was observed at lower flow rates. Increasing the feed flow rate increases CE to a maximum value then decreases it down to zero for all cell voltages and feed concentrations. In the case of higher feed concentrations, maximum values of CE are obtained at higher flow rates. As expected, in almost all experiments, CE increases by intensifying cell voltage. CE values of up to 48 indicate effective ion transfer across the ion exchange membranes in spite of low separation performance of the ED cell.

Determining Benefits and Costs of Improved Water Heater Efficiencies Determining Benefits and Costs of Improved Water Heater Efficiencies Title Determining Benefits and Costs of Improved Water Heater Efficiencies Publication Type Report LBNL Report Number LBNL-45618 Year of Publication 2000 Authors Lekov, Alexander B., James D. Lutz, Xiaomin Liu, Camilla Dunham Whitehead, and James E. McMahon Document Number LBNL-45618 Date Published May 4 Abstract Economic impacts on individual consumers from possible revisions to U.S. residential water heater energy-efficiency standards are examined using a life-cycle cost (LCC) analysis. LCC is the consumer's cost of purchasing and installing a water heater and operating it over its lifetime. This approach makes it possible to evaluate the economic impacts on individual consumers from the revised standards. The methodology allows an examination of groups of the population which benefit or lose from suggested efficiency standards. The results show that the economic benefits to consumers are significant. At the efficiency level examined in this paper, 35% of households with electric water heaters experience LCC savings, with an average savings of $106, while 4% show LCC losses, with an average loss of $40 compared to a pre-standard LCC average of $2,565. The remainder of the population (61%) are largely unaffected.

FORSCOM installation characterization and ranking for water efficiency improvement  

SciTech Connect

On March 11, 1994, President Clinton signed Executive Order 12902-Energy Efficiency and Water Conservation at Federal Facilities. Section 302 of the Executive Order calls for energy and water prioritization surveys of federal facilities to be conducted. The surveys will be used to establish priorities for conducting comprehensive facility audits. In response to the requirements of the Executive Order, the U.S. Army Forces Command (FORSCOM) has tasked Pacific Northwest Laboratory (PNL) to initiate a broad study of the water savings potential at each of its major installations. This report provides an assessment of the water, sewer, energy (for hot water production and pumping), and associated cost savings potential at ten of the major FORSCOM installations. This assessment is meant to be a {open_quotes}first pass{close_quotes} estimate of the water savings potential, to assist FORSCOM in prioritizing installations for detailed water audits and potential water efficient retrofits. In addition, the end uses (toilets, sinks, showerheads, irrigation, etc.) with the greatest water savings potential are identified at each installation. This report is organized in the following manner. Following this Introduction, Section 2 provides important background information pertaining to the water analysis. Section 3 describes the methodology employed in the analysis, and Section 4 summarizes the study results. Section 5 prioritizes the installations based on both water/sewer savings and cost associated with water, sewer, and energy savings. Section 6 provides recommendations on where to start detailed water audits, as well as other recommendations. References are listed in Section 7. The appendices provide specific information on the analysis results and methodology, along with a discussion of special issues.

Improving water and energy metabolism efficiency in urban water supply system through pressure stabilization by optimal operation on water tanks  

Science Journals Connector (OSTI)

Abstract Water supply consumes 23% of the worldwide energy. Water distribution system, which accounts for 70% electricity consumption of water supply, is a key link of urban water and energy metabolism. The operation of the secondary water supply system (SWSS) has great influence on the pressure stability and associated energy consumption as well as water loss of urban water distribution. This research developed an approach based on the hydraulic solver EPANET and genetic algorithm (GA) to investigate the impacts of two different operation strategies, user demand regulation (UDR) and tank level regulation (TLR) of SWSS, on pressure stability and energy efficiency. The results showed that the strategy of TLR could reduce the pressure fluctuations and increase the minimal pressure of the distribution network under the same supplydemand condition. Reduction of the pressure fluctuations is beneficial to the reliability and leakage control of pipe networks. Increase of the minimal pressure indicates that less energy is lost during the distribution. Therefore, the TLR strategy of SWSS can support to initiatively lower the water pressure of the pumps at the water plant outlet, thus improves the water and energy metabolism efficiency in urban water supply system.

A Stochastic Nonlinear Water Wave Model for Efficient Uncertainty Quantification  

E-Print Network (OSTI)

A major challenge in next-generation industrial applications is to improve numerical analysis by quantifying uncertainties in predictions. In this work we present a stochastic formulation of a fully nonlinear and dispersive potential flow water wave model for the probabilistic description of the evolution waves. This model is discretized using the Stochastic Collocation Method (SCM), which provides an approximate surrogate of the model. This can be used to accurately and efficiently estimate the probability distribution of the unknown time dependent stochastic solution after the forward propagation of uncertainties. We revisit experimental benchmarks often used for validation of deterministic water wave models. We do this using a fully nonlinear and dispersive model and show how uncertainty in the model input can influence the model output. Based on numerical experiments and assumed uncertainties in boundary data, our analysis reveals that some of the known discrepancies from deterministic simulation in compa...

Laboratory evidence for efficient water formation in interstellar ices  

E-Print Network (OSTI)

Even though water is the main constituent in interstellar icy mantles, its chemical origin is not well understood. Three different formation routes have been proposed following hydrogenation of O, O2, or O3, but experimental evidence is largely lacking. We present a solid state astrochemical laboratory study in which one of these routes is tested. For this purpose O2 ice is bombarded by H- or D-atoms under ultra high vacuum conditions at astronomically relevant temperatures ranging from 12 to 28 K. The use of reflection absorption infrared spectroscopy (RAIRS) permits derivation of reaction rates and shows efficient formation of H2O (D2O) with a rate that is surprisingly independent of temperature. This formation route converts O2 into H2O via H2O2 and is found to be orders of magnitude more efficient than previously assumed. It should therefore be considered as an important channel for interstellar water ice formation as illustrated by astrochemical model calculations.

Effects of Tillage Practices on Water Consumption, Water Use Efficiency and Grain Yield in Wheat Field  

Science Journals Connector (OSTI)

Abstract Water shortage is a serious issue threatening the sustainable development of agriculture in the North China Plain, with the winter wheat (Triticum aestivum L.) as its largest water-consuming crop. The effects of tillage practices on the water consumption and water use efficiency (WUE) of wheat under high-yield conditions using supplemental irrigation based on testing soil moisture dynamic change were examined in this study. This experiment was conducted from 2007 to 2010, with five tillage practice treatments, namely, strip rotary tillage (SR), strip rotary tillage after subsoiling (SRS), rotary tillage (R), rotary tillage after subsoiling (RS), and plowing tillage (P). The results showed that in the SRS and RS treatments the total water and soil water consumptions were 11.81, 25.18% and 12.16, 14.75% higher than those in SR and R treatments, respectively. The lowest ratio of irrigation consumption to total water consumption in the SRS treatment was 18.53 and 21.88% for the 20082009 and 20092010 growing seasons, respectively. However, the highest percentage of water consumption was found in the SRS treatment from anthesis to maturity. No significant difference was found between the WUE of the flag leaf at the later filling stage in the SRS and RS treatments, but the flag leaf WUE at these stages were higher than those of other treatments. The SRS and RS treatments exhibited the highest grain yield (9573.76 and 9507.49 kg ha?1 for 3-yr average) with no significant difference between the two treatments, followed by P, R and SR treatments. But the SRS treatment had the highest WUE. Thus, the 1-yr subsoiling tillage, plus 2 yr of strip rotary planting operation may be an efficient measure to increase wheat yield and WUE.

The impact of water and nitrogen limitation on maize biomass and resource-use efficiencies for radiation, water and nitrogen  

Science Journals Connector (OSTI)

Abstract The impact of limited water and nitrogen (N) supply on maize productivity and on the utilisation efficiency of key production resources (radiation, water and N) was quantified in two field experiments during consecutive seasons in Canterbury, New Zealand. In experiment 1 crops were subjected to five N treatment rates (0400kgN/ha) and, in experiment 2, to three N (0 to 250kg/haN) and two water regimes (dryland and fully irrigated) using a rain-shelter structure. Limited N and water reduced yield and affected resource-use efficiencies. Total biomass ranged from 8Mg DM/ha for dryland nil N crops to up to 28MgDM/ha for fully irrigated and N fertilised crops. Radiation use efficiency declined with N and water limitation from a maximum of 1.4gDM/MJ to 0.6g DM/MJ. Transpiration water use efficiency was higher in water stressed crops than irrigated crops (5070kgDM/ha/mm) and increased linearly with N fertilizer rates in proportion to the increase in radiation use efficiency. The crop conductance decreased from 0.19mm/MJ in irrigated crops to 0.07mm/MJ in dryland crops with negligible response to N fertilizer rates. Nitrogen use efficiency declined with N input rates from 100 to 150kg DM/kg N, being inversely related to the efficiency of both water and radiation use. Dryland crops recovered 25% less N from applied fertilizer than irrigated crops. These results highlight that benchmarks of resource efficiency need to consider the level of intensification of the production system and illustrate trade-offs between yield targets and the efficiency of water and N use, that depend on the scale of analysis. To establish a balance between economic returns and environmental impacts, these trade-offs need to be managed depending on the relative values assigned to the use-efficiency of each input resource in relation to crop productivity.

Investment efficiency in the Italian water service industry: a benchmarking study using data envelopment analysis (DEA)  

Science Journals Connector (OSTI)

The paper presents a benchmarking study of the Italian water service industry using data envelopment analysis. Sample investigated in the study includes 38 optimal territorial areas (ATOs), where the ATO is a well circumscribed geographical area where the provision of integrated water services is considered efficient. Results of DEA implementation show that the average pure technical and scale efficiency are situated at 92.62% and 93.91%, respectively, while the average technical efficiencies score is 87.61%. Findings also support the idea that there might be an optimal size of ATOs which is associated to higher efficiency scores and that agglomeration economies are important in the provision of water integrated services. Large scale operations and ATO size are associated to lower efficiency rates.

Highly efficient photochemical HCOOH production from CO{sub 2} and water using an inorganic system  

SciTech Connect

We have constructed a system that uses solar energy to react CO{sub 2} with water to generate formic acid (HCOOH) at an energy conversion efficiency of 0.15%. It consists of an AlGaN/GaN anode photoelectrode and indium (In) cathode that are electrically connected outside of the reactor cell. High energy conversion efficiency is realized due to a high quantum efficiency of 28% at 300 nm, attributable to efficient electron-hole separation in the semiconductor's heterostructure. The efficiency is close to that of natural photosynthesis in plants, and what is more, the reaction product (HCOOH) can be used as a renewable energy source.

An International Survey of Electric Storage Tank Water Heater Efficiency and Standards  

SciTech Connect

Water heating is a main consumer of energy in households, especially in temperate and cold climates. In South Africa, where hot water is typically provided by electric resistance storage tank water heaters (geysers), water heating energy consumption exceeds cooking, refrigeration, and lighting to be the most consumptive single electric appliance in the home. A recent analysis for the Department of Trade and Industry (DTI) performed by the authors estimated that standing losses from electric geysers contributed over 1,000 kWh to the annual electricity bill for South African households that used them. In order to reduce this burden, the South African government is currently pursuing a programme of Energy Efficiency Standards and Labelling (EES&L) for electric appliances, including geysers. In addition, Eskom has a history of promoting heat pump water heaters (HPWH) through incentive programs, which can further reduce energy consumption. This paper provides a survey of international electric storage water heater test procedures and efficiency metrics which can serve as a reference for comparison with proposed geyser standards and ratings in South Africa. Additionally it provides a sample of efficiency technologies employed to improve the efficiency of electric storage water heaters, and outlines programs to promote adoption of improved efficiency. Finally, it surveys current programs used to promote HPWH and considers the potential for this technology to address peak demand more effectively than reduction of standby losses alone

Hierarchical heteroarchitectures functionalized membrane for high efficient water purification  

Science Journals Connector (OSTI)

Abstract Heterojunctioned architectures were facilely fabricated using hydrothermally treated electrospun TiO2 nanofibers in an alkaline Sr(NO3)2 precursor solution in an electronic oven. TiO2 on the fiber surface was partially dissolved into Ti4+ to react with Sr2+ in favor of the nucleation of SrTiO3 on TiO2 nanofibers, and thus a heterojunction was formed between SrTiO3 and TiO2, which will benefit the improvement of photocatalytic activity. And then a multifunctional membrane was created by functionalizing the surface of commercial cellulose acetate (CA) membrane with heterojunctioned SrTiO3/TiO2 nanofibers. This newly structured membrane exhibited excellent water purification performances in a concurrent photocatalytic membrane filtration system under the irradiation of UV light, because it is able to integrate the advantages of photocatalysis and membrane filtration while minimizes their disadvantages. The high water purification performances in terms of high photodegradation ability and high permeate flux are attributed to the high photocatalytic activity of heterojunctioned SrTiO3/TiO2 nanofibers architectures and their structured porous functional layer favorable for fast water pass through.

Feasibility study of broadband efficient ''water window'' source  

SciTech Connect

We demonstrate a table-top broadband emission water window source based on laser-produced high-Z plasmas. Resonance emission from multiply charged ions merges to produce intense unresolved transition arrays (UTAs) in the 2-4 nm region, extending below the carbon K edge (4.37 nm). Arrays resulting from n=4-n=4 transitions are overlaid with n=4-n=5 emission and shift to shorter wavelength with increasing atomic number. An outline of a microscope design for single-shot live cell imaging is proposed based on a bismuth plasma UTA source, coupled to multilayer mirror optics.

Subsidiary Authors Energy Analysis Department Document Number LBNL-5187E Pagination 21 Date Published January Publisher Lawrence Berkeley National Laboratory City Berkeley ISBN Number LBNL-5187E Abstract The American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) Standards Project Committee (SPC) 118.2, Method of Testing for Rating Residential Water Heaters, is seeking to improve the test procedure used for measuring the energy efficiency of residential gas and electric water heaters. ASHRAE is seeking to develop an improved test procedure in part to support the U.S. Department of Energy's (DOE's) desire to update and amend the water heater test procedure underlying the minimum energy efficiency standards for water heaters. DOE's test procedures are often based on or reference ASHRAE standards.DOE's most recent minimum energy performance standards (MEPS) for residential water heaters were promulgated in 2010.[1] The associated test procedures are stipulated in the Code of Federal Regulations (CFR).[2] Although DOE currently is conducting a rulemaking to review and possibly amend the test procedures for residential water heaters, that rulemaking pertains to accounting for energy consumed during standby and off modes. In its notice of proposed rulemaking published in the Federal Register on August 30, 2010, DOE tentatively concluded that the test procedure for water heaters already fully accounts for and incorporates the energy consumed during standby and off modes [3].

Chapter 6 - Resource (Land, Water, Nutrient, and Pesticide) Use and Efficiency of Corn and Sorghum  

Science Journals Connector (OSTI)

Crop resource use efficiency, defined as the ratio of crop output over input, has been an essential tool for crop selection. The objective of the review presented in this chapter was to compare corn and sorghum based on their land, water, nutrient, and pesticide use efficiencies. Data from corn and sorghum hybrid trials, herbicide performance trials, long-term fertilizer trials, and journal and extension papers were assembled for this comparison. Results indicated that about 6Mgha?1 is the cutoff value above which corn, and below which sorghum, has better land use efficiencies at equal net revenues. Based on relationships between evapotranspiration (ET) and yield described in the literature, about 537mm of ET was found to be the cutoff above which corn, and below which sorghum, has better water use efficiencies. In rainfed production, approximately 432mm of total seasonal rainfall (April to September) was the threshold value above which corn, and below which sorghum, has better rainfall use efficiencies on an average. Fertilizer use efficiency of corn was found to be greater than that of sorghum at all application rates, as long as water is not limiting. Preemergent pesticide application has increased yield up to 100% compared to untreated plots in both corn and sorghum. However, unlike corn, sorghum postemergent herbicides were either not available for some weed species, relatively more expensive, or not as effective as preemergent herbicide application. A preliminary estimate of the possible cutoff yield based on general net return from the two crop is presented.

Evaluation of the efficiency of polysulfone ultrafiltration membrane-based water purifiers for microbiological decontamination  

Science Journals Connector (OSTI)

Indigenously developed polysulfone Ultrafiltration (UF) membrane-based domestic and industrial water purification units were evaluated for their ability to filter bacteria and viruses from water. Escherichia coli (105 cfu/ml) and P1 phage (106 pfu/ml) were filtered through a Domestic Water Purifier (DWP) (dead-end UF unit) and a large-scale spiral water purifier (cross-flow UF unit) and the filtrates were analysed for bacterial and phage counts. Both units were found to be efficient in the complete removal of E. coli and a 99.99% removal of the P1 phage was observed. Both the domestic and industrial water purifiers are highly efficient in the removal of bacteria and viruses. UF membranes were also characterised for Molecular Weight Cut-Off (MWCO) by the polyethylene glycol and polyethylene oxide methods, which showed that MWCO was 6065 kDa. These MWCO results were further validated using the Bovine Serum Albumin (BSA) rejection behaviour of these membranes, which showed about 90% rejection. The technique involving the estimation of MWCO, coupled with the rejection characteristics of E. coli and P1 phage, provides an excellent tool to evaluate the efficiency of water purifiers based on UF membrane technology.

Opportunities for improving leaf water use efficiency under climate change conditions  

Science Journals Connector (OSTI)

Abstract \\{WUEi\\} (intrinsic water use efficiency) is a complex (multi)-trait, that depends on several physiological processes, driving plant productivity and its relation with a changing environment. Climatic change predictions estimate increases in temperature and drought in the semi-arid regions, rendering improved water use efficiency is a mandatory objective to maintain the current global food supply. The aims of this review were (i) to identify through a meta-analysis the leaf traits mostly related to intrinsic water use efficiency (WUEi, the ratio between A net photosynthesis and gs stomatal conductance), based on a newly compiled dataset covering more than 200 species/varieties and 106 genus of C3 plants (ii) to describe the main potential targets for \\{WUEi\\} improvement via biotechnological manipulations and (iii) to introduce emergent and innovative technologies including \\{UAVs\\} (Unmanned Aerial Vehicles) to scale up levels from leaf to whole plant water status. We confirmed that increases in gm/gs and Vcmax/gs ratios are systematically related with increases in \\{WUEi\\} maintained across species, habitats, and environmental conditions. Other emergent opportunities to improve \\{WUEi\\} are described such as the relationship between photosynthesis and respiration and their link with metabolomics. Finally, we outline our hypothesis that we are observing the advent of a smart agriculture, wherein new technologies, such as \\{UAVs\\} equipped with remote sensors will rapidly facilitate an efficient water use regulating the irrigation schedule and determination, under field conditions, of cultivars with improved water use efficiency. We, therefore, conclude that the multi-disciplinary challenge toward WUE has only just begun.

Investigation of the basic physics of high efficiency semiconductor hot carrier solar cell. Annual status report, 31 May 1994-30 May 1995  

SciTech Connect

The main purpose of this research program is to investigate potential semiconductor materials and their multi-band-gap MQW (multiple quantum wells) structures for high efficiency solar cells for aerospace and commercial applications. The absorption and PL (photoluminescence) spectra, the carrier dynamics, and band structures have been investigated for semiconductors of InP, GaP, GaInP, and InGaAsP/InP MQW structures, and for semiconductors of GaAs and AlGaAs by previous measurements. The barrier potential design criteria for achieving maximum energy conversion efficiency, and the resonant tunneling time as a function of barrier width in high efficiency MQW solar cell structures have also been investigated in the first two years. Based on previous carrier dynamics measurements and the time-dependent short circuit current density calculations, an InAs/InGaAs - InGaAs/GaAs - GaAs/AlGaAs MQW solar cell structure with 15 bandgaps has been designed. The absorption and PL spectra in InGaAsP/InP bulk and MQW structures were measured at room temperature and 77 K with different pump wavelength and intensity, to search for resonant states that may affect the solar cell activities. Time-resolved IR absorption for InGaAsP/InP bulk and MQW structures has been measured by femtosecond visible-pump and IR-probe absorption spectroscopy. This, with the absorption and PL measurements, will be helpful to understand the basic physics and device performance in multi-bandgap InAs/InGaAs - InGaAs/InP - InP/InGaP MQW solar cells. In particular, the lifetime of the photoexcited hot electrons is an important parameter for the device operation of InGaAsP/InP MQW solar cells working in the resonant tunneling conditions. Lastly, time evolution of the hot electron relaxation in GaAs has been measured in the temperature range of 4 K through 288 K using femtosecond pump-IR-probe absorption technique.

Aquaporins are major determinants of water use efficiency of rice plants in the field  

Science Journals Connector (OSTI)

Abstract This study aimed at specifying the reasons of unbalanced water relations of rice in the field at midday which results in slowing down photosynthesis and reducing water use efficiency (WUE) in japonica and indica rice under well-watered and droughted conditions. Leaf relative water content (RWC) decreased in the well-watered plants at midday in the field, but more dramatically in the droughted indica (75.6 and 71.4%) than japonica cultivars (85.5 and 80.8%). Gas exchange was measured at three points during the day (9:00, 13:00 and 17:00). Leaf internal CO2 (Ci) was not depleted when midday stomatal depression was highest indicating that Ci was not limiting to photosynthesis. Most aquaporins were predominantly expressed in leaves suggesting higher water permeability in leaves than in roots. The expression of leaf aquaporins was further induced by drought at 9:00 without comparable responses in roots. The data suggest that aquaporin expression in the root endodermis was limiting to water uptake. Upon removal of the radial barriers to water flow in roots, transpiration increased instantly and photosynthesis increased after 4h resulting in increasing WUE after 4h, demonstrating that WUE in rice is largely limited by the inadequate aquaporin expression profiles in roots.

Improving Energy Efficiency and Enabling Water Recycle in Biorefineries Using Bioelectrochemical Cells.  

SciTech Connect

Improving biofuel yield and water reuse are two important issues in further development of biorefineries. The total energy content of liquid fuels (including ethanol and hydrocarbon) produced from cellulosic biomass via biochemical or hybrid bio-thermochemical routes can vary from 49% to 70% of the biomass entering the biorefinery, on an energy basis. Use of boiler for combustion of residual organics and lignin results in significant energy and water losses. An alternate process to improve energy recovery from the residual organic streams is via use of bioelectrochemical systems such as microbial fuel cells (MFCs) microbial electrolysis cells (MECs). The potential advantages of this alternative scheme in a biorefinery include minimization of heat loss and generation of a higher value product, hydrogen. The need for 5-15 gallons of water per gallon of ethanol can be reduced significantly via recycle of water after MEC treatment. Removal of inhibitory byproducts such as furans, phenolics and acetate in MFC/MECs to generate energy, thus, has dual advantages including improvements in energy efficiency and ability to recycle water. Conversion of the sugar- and lignin- degradation products to hydrogen is synergistic with biorefinery hydrogen requirements for upgrading F-T liquids and other byproducts to high-octane fuels and/or high value products. Some of these products include sorbitol, succinic acid, furan and levulinate derivatives, glycols, polyols, 1,4-butenadiol, phenolics polymers, etc. Potential process alternatives utilizing MECs in biorefineries capable of improving energy efficiency by up to 30% are discussed.

Beyond limits and efficiency, what? Assessing developments in EU water policy  

Science Journals Connector (OSTI)

This paper documents a transformation of EU water policy from a standard-based approach towards a more diverse policy combining ecological, economic and social elements with an emphasis on institutional and participatory aspects. This is marked in a new Water Framework Directive. Analysis is supported by a theoretical discussion of different approaches to sustainability and recognition of the deadlock of an ecological limit vs. economic efficiency dichotomy. While an approach originating from works in institutional and ecological economics and emphasising processes, justice and collective decisions seems to break this impasse, it is not without its own conceptual problems.

The performance of a parabolic trough collector (PTC) manufactured in Merida Yucatn was evaluated under the ANSI/ASHRAE 93-1986 standard. The water heating system for testing with a constant flow limited to a maximum temperature of 55 C was built; thus the tests were at low temperatures. Using water as working fluid it was found that the maximum efficiency of the collector was 5.43% with a flow rate of 0.022?kg/s at a direct solar irradiance with incidence angle 0. The evaluation methodology and design of the system for testing the collector is reported in this paper.

Water Use Efficiency, Irrigation Management and Nitrogen Utilization in Rice Production in the North of Iran  

Science Journals Connector (OSTI)

Abstract Iran with nearly 165 million hectare of land area and amount of rainfall equal to 300mm in 67% of its territorial land, is considered as a semi-dry region in the world. Rice production in Iran needs to be increased to feed a growing population, whereas water for irrigation is getting scarce. One way to decrease water consumption in paddy field is the change of irrigation regime and replacement of continuous submergence to alternate submergence. In order to investigate the effect of different regimes of irrigation and nitrogen fertilizer on yield of hybrid rice, an experiment was conducted at the Rice Research Institute of Iran during crop season 2008. The experiment was arranged in split plot based on completely randomized block design with 3 replications in which water regimes were main factor included continuous submergence and alternately submergence (irrigation intervals of 5, 8 and 11days) and nitrogen fertilizer levels were sub factor included 0, 90, 120 and 150kg/ha. Grain yield,water use efficiency,relative water content,total nitrogen,grain nitrogen and nitrogen harvest index were statistically the same under continuous submergence and irrigation interval of 5 and 8 days and were lowest in 11- day interval.total nitrogen,grain nitrogen and nitrogen harvest index decreased with the increment of nitrogen.we concluded that 8- day interval could reduce water consumption in paddy fields in the North of Iran.

Analysis of space heating and domestic hot water systems for energy-efficient residential buildings  

SciTech Connect

An analysis of the best ways of meeting the space heating and domestic hot water (DHW) needs of new energy-efficient houses with very low requirements for space heat is provided. The DHW load is about equal to the space heating load in such houses in northern climates. The equipment options which should be considered are discussed, including new equipment recently introduced in the market. It is concluded that the first consideration in selecting systems for energy-efficient houses should be identification of the air moving needs of the house for heat distribution, heat storage, ventilation, and ventilative cooling. This is followed, in order, by selection of the most appropriate distribution system, the heating appliances and controls, and the preferred energy source, gas, oil, or electricity.

Effective three-dimensional superhydrophobic aerogel-coated channel for high efficiency water-droplet transport  

Science Journals Connector (OSTI)

Three-dimensional superhydrophobic surfaces have been used effectively to optimize droplet transport efficiency in diverse fluidic systems. However the fabrication methods for superhydrophobic surfaces applicable to fluidic devices usually involve complicated process. Herein we report a simple but effective method of fabricating a superhydrophobic surface using organically modified silica aerogel. Superhydrophobic aerogel thin film having highly porous micro/nanostructured surface with methyl groups was realized inside a 3D channel by coating it. To demonstrate that the aerogel-coated surface effectively facilitates movement of water droplets the droplet-based flow characteristics regarding the triple line were conducted.

Ionic liquid effects on mass transfer efficiency in extractive distillation of waterethanol mixtures  

Science Journals Connector (OSTI)

Abstract The relatively high viscosities of ionic liquids could reduce the mass transfer efficiency of the extractive distillation process. The rate-based model was adopted to analyze this phenomenon since it predicted the performance of an extractive distillation pilot plant using ionic liquids as solvent. For the waterethanol separation, three ionic liquids: 1-ethyl-3-methylimidazolium chloride, 1-ethyl-3-methylimidazolium acetate and 1-ethyl-3-methylimidazolium dicyanamide and the organic solvent ethylene glycol were used for the analysis. Simulations were conducted for sieve trays and Mellapak 250Y. The results indicate that relatively high viscosities affect the mass transfer efficiency. However, the improvements in relative volatilities obtained from the ionic liquids help to overcome this effect. However, with high solvent viscosities (>65mPas at T=353.15K) it was not possible to overcome the reductions. Additionally, at higher distillate rates high relative volatilities yielded negative effects on mass transfer efficiency because of a decrease in vapor velocity.

Effects of different irrigation regimes on yield and water use efficiency of cucumber crop  

Science Journals Connector (OSTI)

Abstract This study was conducted to investigate the effects of four irrigation regimes on yield, growth parameters and water use efficiency of cucumber crop under greenhouse cultivation. A field experiment was carried out at the experimental farm of Palestine Technical University Kadoorie, located at Tulkarm, Palestine. Cucumber seedlings were planted on 14 February 2012 in greenhouse at a rate of 1500 seedlings per 1000 square meters. Four irrigation regimes were examined during the growing period as follows: farmer irrigation (FI), tensiometer based irrigation (TI), irrigation at full \\{ETc\\} data (ETc), and irrigation at 70% of \\{ETc\\} (70% ETc). Plant data were collected during the growing period for evaluating the total yield, plant height, number of harvested fruits per plant, weight of harvested fruits per plant, dry matter of above and under ground parts. The results indicated that the 70% \\{ETc\\} treatment obtained the highest crop yield followed by ETc, FI, and TI treatments, respectively. On average, cucumber yield under 70% \\{ETc\\} treatment was 24%, 6% and 4% higher than that under TI, FI and \\{ETc\\} treatments, respectively. At the end of harvesting stage plant height, above-ground dry matter obtained by 70% \\{ETc\\} treatment was higher than the other treatments. The smallest plant height and dry matter was obtained under TI treatment. Results also indicated that, when using scheduled irrigation methods large amount of water were saved and found to be 139, 104 and 26mm for TI, 70% \\{ETc\\} and \\{ETc\\} treatments, respectively, compared to FI treatment. The highest water use efficiency (WUE) was obtained under 70% \\{ETc\\} treatment followed by ETc, TI and FI treatments, respectively.

Basic Bacteria Basic Bacteria Name: Valerie Location: N/A Country: N/A Date: N/A Question: I'm doing a science project on bacteria. WHat I'm doing is washing forks with different dishwashing liquids, then wiping any remaining bacteria on to Agar petri dishes. Then incubating it and seeing which soap removed the most. My question is what kind of bacteria would be growing? and also do I just count the colonies to compare? and how long and at what temperature should I incubate this bacteria? Thank you very much for your time. I'll be looking forward to your response. Replies: The temperature is easy: 37 degrees C is optimal for many bacteria. The medium will determine which bacteria grow best. So if you don't see growth on one medium, but you see growth on another, it tells you that there is a difference in nutrients present in those media that is required for that bacteria. Look at your plates after 24 hr, then put them back in the incubator (keep them sterile) and look at them after 48 hrs--do you see the difference? any slow-growing bacteria visible or did the fast-growing take over the complete plate?

Ecosystem water use efficiency for a sparse vineyard in arid northwest China  

Science Journals Connector (OSTI)

Abstract Ecosystem water use efficiency (WUE) can be defined as the ratio of net CO2 exchange to evapotranspiration, which implicates the interactions between carbon sequestration and water consumption. Previous studies mainly focused on ecosystem WUE for forests, grasslands and farmlands, but paid little attention to the sparse vineyard. How the vineyard WUE varied on daily and seasonal time scales remains uncertain. The vineyard CO2 and water fluxes were measured by the eddy covariance method during 2008 in arid northwest China to address the issues. Results indicate that the seasonal variation of vineyard WUE presented a downward-parabolic trend, with a mean value of 4mgg?1and a maximum value of 10mgg?1. Compared with other ecosystems, WUE for vineyard was lower than that for forests, maize, wheat and wetlands, but higher than grasslands and Savannas. The severely dry climate and the sparse vegetation led the results. Such factors as radiation, air temperature and humidity, soil moisture, canopy conductance and leaf area index all exerted significant influences on vineyard WUE. However, the vineyard WUE was highly sensitive to solar radiation and air temperature changes, and it decreased significantly with the rising radiation and temperature, which is remarkably different from previous studies. Such results were mainly due to the great impact on CO2 exchange exerted by soil layer in the sparse vineyard, and the high sensitivity of soil respiration to temperature changes induced by radiation and air temperature. The CO2 assimilation reduced with the increasing radiation and air temperature, however the vineyard evapotranspiration increased rapidly, thus the vineyard WUE declined significantly with the rising radiation and air temperature. These results provided a new insight for understanding the carbon and water cycles over the sparse vegetation.

Sunspace basics  

SciTech Connect

Anyone who lives in a home with a sunspace will tell you that the sunspace is the most enjoyable room in the house. Many times the homeowner`s only regret is that the sunspace is not larger. Although aesthetics often drive the decision to add a sunspace or include one in a new home design, sunspaces can also provide supplemental space heating and a healthy environment for plants and people. In fact, a well-designed sunspace can provide up to 60% of a home`s winter heating requirements. This publication addresses basic elements of sunspace design; design considerations for supplemental space heating, growing plants, and use as a living space; design guidelines including siting, heat distribution, and glazing angles; and major sunspace components including glazing options, thermal mass, insulation, and climate controls. A list of sources for more information is also provided.

The public policies for reducing nonpoint water pollution between equity and efficiency  

Science Journals Connector (OSTI)

This paper investigates if and how equity and efficiency could be reconciled when improving nitrogen-polluted groundwater of agricultural origin. This is achieved through comparing two pollution control programmes with respect to their costs, water quality impacts and correlation between abatement cost and polluting emissions. The fieldwork was done in a watershed, near the French Alps. It was carried out by economists in close relation with agronomists and hydrologists. The difficulty of the assessment of the environmental impact of the foreseen technological scenarios is overcome by developing an indicator of environmental effectiveness able to grasp the level of nitrate pollution of agricultural origin and to check whether the pollution control programmes are able to reach the given environmental target or not. The results show that it is only in the framework of a more flexible regulatory system that total abatement costs are reduced, and equity and efficiency reconciled,. This is due to the specific situation in agriculture the combination of various productions in every farm. This characteristic explains why the heterogeneity of the abatement costs is more significant within the firm (between production systems) rather than between firms.

The isohydric cv. Montepulciano (Vitis vinifera L.) does not improve its whole-plant water use efficiency when subjected to pre-veraison water stress  

Science Journals Connector (OSTI)

Abstract Understanding how water use efficiency (WUE) changes under drought is crucial for interpreting adaptive responses of species and cultivars to such abiotic stress. Several recent papers have concluded that in grapevine these responses and the guidelines stemming therefrom can differ, depending upon the parameter chosen to express WUE. In the present paper a complete set of WUE expressions, including the physiological and agronomical, were compared in potted, fruiting cv. Montepulciano (Vitis vinifera L.) grapevines which were either well watered (WW) or subjected to progressive pre-veraison drought (WS) by supplying decreasing fractions (i.e. 70%, 50% and 30% of daily vine transpiration, Tg) determined gravimetrically before vines were fully rewatered. While single-leaf intrinsic water-use efficiency (WUEi) increased with water stress severity, seasonal and diurnal whole-canopy WUE were similar at pre-stress, 70% Tg, and upon rewatering but dropped in WS during severe water stress. Agronomic WUE calculated as mass of dry weight stored in annual biomass (leaves, canes and bunches) per L of water used, was also lower in WS, whereas WS had similar must composition with WW despite a 37% reduction in the yield per vine. Results warn that whole-canopy WUE is a much better index than any single-leaf based WUE parameter for extrapolation to agronomic WUE and actual grape composition. Under our specific case study, it can be recommended that, to avoid significant profit loss, water supply to drought stressed Montepulciano at pre-veraison should not be lower than 70% of daily vine water use.

Responses of rice yield, irrigation water requirement and water use efficiency to climate change in China: Historical simulation and future projections  

Science Journals Connector (OSTI)

Abstract Rice is one of most important crops in China, accounting for approximately 18% of total cultivated area. Rice productivity is significantly affected by undergoing climate change and vulnerable with water stress. Therefore, investigating the responses of rice growth and water resources utilization to more pronounced climate change is of great importance for water resources planning and management in terms of maintaining the ecosystem integrity and ensuring the food security. In this study, the changes of rice yield, water consumption (ET), irrigation water requirement (IWR), water use efficiency (WUE) and irrigation water use efficiency (IWUE) from 1961 to 2010 in three typical sites (Kunshan and Nanjing in the Yangtze River Basin, and Kaifeng in the Yellow River Basin) in rice plantation region of China were evaluated by means of validated rice crop model ORYZA2000. Their responses to future climate scenarios of 21 century were investigated by driving ORYZA2000 with downscaling climatic data from HadCM3 (Hadley Centre Coupled Model version 3) under A2 and B2 emission scenarios with the help of a statistical downscaling method (SDSM). The results exhibit a significant decline in rice yield was identified by 49.3kgha?1, 32.0kgha?1 and 45.8kgha?1 for Kunshan station, Nanjing station and Kaifeng station, respectively, in the past 50 years due to obviously shortened rice growth duration (0.20daya?1, 0.15daya?1 and 0.27daya?1, respectively). While changes of ET and IWE were different for three stations representing by significant increase of ET and IWE in Kunshan, non-significant increase in Nanjing and significant decrease in Kaifeng. Whereas accompanying production reduction, simulated WUE and IWUE for three stations all presented significant deceasing trends ranging from 0.06kgha?1mm?1 to 0.16kgha?1mm?1. The future projection results under IPCC SRES A2 and B2 emission scenarios indicated the generally negative effect of climate warming to rice yield (maximum by ?18.9% decline in 2090s in Kunshan) during the 21 century due to remarkable shortened growth period, resulting in generally depressed WUE and IWUE, although there would be the distinct response of the ET and IWR to future climate change for the three stations. Meanwhile, the increase of CO2 concentration under future climate is beneficial to raise the rice yield, alleviate crop water consumption and irrigation water requirements and improve the water use efficiencies of rice in a certain degree. Further works should be carried out to capture simulation uncertainties in climate change impact assessment with consideration of interactions among anthropogenic activities, environmental and biological factors.

Microhydropower Basics | Department of Energy  

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Basics Basics Microhydropower Basics August 15, 2013 - 3:09pm Addthis Microhydropower systems are small hydroelectric power systems of less than 100 kilowatts (kW) used to produce mechanical energy or electricity for farms, ranches, homes, and villages. How a Microhydropower System Works All hydropower systems use the energy of flowing water to produce electricity or mechanical energy. Although there are several ways to harness moving water to produce energy, "run-of-the-river systems," which do not require large storage reservoirs, are most often used for microhydropower systems. Illustration of an example microhydropower system. A river flows down from some hills. The river first flows through an intake, which is indicated as two white walls on each side of the river. The intake diverts water to a canal. From the canal, the water travels to a forebay, which looks like a white, rectangular, aboveground pool. A pipeline, called a penstock, extends from the forebay to a building, called the powerhouse. You can see inside the powerhouse, which contains a turbine and other electric generation equipment. The water flows in and out of the powerhouse, returning to the river. Power lines also extend from the powerhouse, along and through two electrical towers, to a house that sits near the river's edge.

High Efficiency Generation of Hydrogen Fuels Using Solar Thermochemical Splitting of Water  

SciTech Connect

The objective of this work is to identify economically feasible concepts for the production of hydrogen from water using solar energy. The ultimate project objective was to select one or more competitive concepts for pilot-scale demonstration using concentrated solar energy. Results of pilot scale plant performance would be used as foundation for seeking public and private resources for full-scale plant development and testing. Economical success in this venture would afford the public with a renewable and limitless source of energy carrier for use in electric power load-leveling and as a carbon-free transportation fuel. The Solar Hydrogen Generation Research (SHGR) project embraces technologies relevant to hydrogen research under the Office of Hydrogen Fuel Cells and Infrastructure Technology (HFCIT) as well as concentrated solar power under the Office of Solar Energy Technologies (SET). Although the photoelectrochemical work is aligned with HFCIT, some of the technologies in this effort are also consistent with the skills and technologies found in concentrated solar power and photovoltaic technology under the Office of Solar Energy Technologies (SET). Hydrogen production by thermo-chemical water-splitting is a chemical process that accomplishes the decomposition of water into hydrogen and oxygen using only heat or a combination of heat and electrolysis instead of pure electrolysis and meets the goals for hydrogen production using only water and renewable solar energy as feed-stocks. Photoelectrochemical hydrogen production also meets these goals by implementing photo-electrolysis at the surface of a semiconductor in contact with an electrolyte with bias provided by a photovoltaic source. Here, water splitting is a photo-electrolytic process in which hydrogen is produced using only solar photons and water as feed-stocks. The thermochemical hydrogen task engendered formal collaborations among two universities, three national laboratories and two private sector entities. The photoelectrochemical hydrogen task included formal collaborations with three universities and one national laboratory. The formal participants in these two tasks are listed above. Informal collaborations in both projects included one additional university (the University of Nevada, Reno) and two additional national laboratories (Lawrence Livermore National Laboratory and Lawrence Berkeley National Laboratory).

Energy Storage Basics Energy Storage Basics The demand for electricity is seldom constant over time. Excess generating capacity available during periods of low demand can be used to energize an energy storage device. The stored energy can then be used to provide electricity during periods of high demand, helping to reduce power system loads during these times. Energy storage can improve the efficiency and reliability of the electric utility system by reducing the requirements for spinning reserves to meet peak power demands, making better use of efficient baseload generation, and allowing greater use of renewable energy technologies. A "spinning reserve" is a generator that is spinning and synchronized with the grid, ready for immediate power generation - like a car engine running with the gearbox

Advances in the development of energy efficient technologies: Sea Water Air Conditioning (SWAC)  

SciTech Connect

Sea water air conditioning (SWAC) is a cost effective and environmentally friendly alternative to and/or enhancement of air conditioning from mechanical chillers. SWAC pumps cold sea water from the appropriate ocean depths (50 to 3,000 feet depending on the climate and local characteristics) to the shore where it replaces (by direct cooling) or enhances (through use as condenser water) large mechanical chillers found in coastal facilities. SWAC direct cooling uses less than twenty per cent of the electricity of a mechanical chiller and uses no refrigerants whatsoever. Indirect cooling also offers substantial energy savings. Both systems dispense with the need for a cooling tower. Technical advances over the last twenty years in corrosion resistant alloys (titanium or aluminum), bio-fouling deterrence, and deep ocean pipeline deployment allow SWAC installations to use reliable, off-the-shelf technology. SWAC works in a variety of climates (existing installations are in Hawaii and Halifax, Nova Scotia), giving it significant domestic and international potential. Economy-of-scale advantages make it attractive to district cooling schemes.

Physiological factors affecting intrinsic water use efficiency of potato clones within a dihaploid mapping population under well-watered and drought-stressed conditions  

Science Journals Connector (OSTI)

Abstract Optimizing crops water use is essential for ensuring food production under future climate scenarios. Therefore, new cultivars that are capable of maintaining production under limited water resource are needed. This study screened for clonal differences in intrinsic water use efficiency (WUEi) within a dihaploid potato (Solanum tuberosum L.) mapping population under well-watered (WW) and drought-stress (DS) conditions. The factorial dependency of \\{WUEi\\} on several plant bio-physiological traits was analyzed, and clonal difference of \\{WUEi\\} was compared. Significant differences in \\{WUEi\\} were found among the clones within the population. Under WW the two clones showing the highest \\{WUEi\\} were significantly different from the two lowest \\{WUEi\\} performing clones. This could only be seen as a trend under DS. Under WW, \\{WUEi\\} differences were closely associated to net photosynthetic rate (An) and nitrogen isotope composition (?15N) in the leaf biomass, but did not relate to stomatal conductance (gs) and carbon isotope composition (?13C) in the leaf biomass. An was found to correlate significantly with leaf nitrogen concentration ([N]leaf) and chlorophyll content index (CCI) under WW. Leaf abscisic acid concentration did not correspond to the changes in gs, indicating that other factors might have been involved in controlling gs among the different clones. Collectively, the clonal differences in \\{WUEi\\} were attributed mainly to the variation in An, which in turn was influenced by plant N metabolism. Clones with high \\{WUEi\\} could be potentially used as material in future breeding programs. Furthermore CCI seemed to be a reliable tool in estimating the clonal An and thereby WUEi.

The effect of adapting cultivars on the water use efficiency of dryland maize (Zea mays L.) in northwestern China  

Science Journals Connector (OSTI)

Abstract Global warming is predicted to have adverse effects on crop productivity and will present an enormous challenge to sustainable development and food security, especially in dryland regions. Prior studies have identified that adapted crop cultivars could effectively act to offset the effects of climate warming; however, the water use of adapted cultivars subject to climate warming is much less understood. We analysed warming trends across the Loess Plateau in north-western China beginning in 1960. There has been significant warming, especially since 1980, with an increase in the growing degree days (GDD, from April to September) of 260330C being observed over the past 30 years. If the maize cultivars had remained unchanged, the decreased yield potential would have been 0.391.83tha?1 over the last 30 years. Meanwhile, the use of historical maize varieties has resulted in significantly decreased water use efficiency (WUE) across the Loess Plateau. Based on the increase in the GDD in each decade, we suggest planting adapted later-maturing maize cultivars to improve productivity. Compared with historical cultivars, the adapted later-maturing varieties significantly prolonged the maize growing cycle by an average of 27 d, thereby increasing the yield potential by 24.264.8% and the WUE by 9.038.1% throughout the Loess Plateau. However, the adapted maturing varieties may increase the water consumption (ET), which is the disadvantage for sustainable dryland farming, especially in dry regions. Hence, continuing to develop water-harvesting techniques (e.g., plastic film mulching) will help to offset the decreasing rainfall and guarantee food security and sustainability in dry regions.

Use of soil and vegetation spectroradiometry to investigate crop water use efficiency of a drip irrigated tomato  

Science Journals Connector (OSTI)

Abstract An agronomic research was conducted in Tuscany (Central Italy) to evaluate the effects of an advanced irrigation system on the water use efficiency (WUE) of a tomato crop and to investigate the ability of soil and vegetation spectroradiometry to detect and map WUE. Irrigation was applied following an innovative approach based on CropSense system. Soil water content was monitored at four soil depths (10, 20, 30 and 50cm) by a probe. Rainfall during the crop cycle reached 162mm and irrigation water applied with a drip system amounted to 207mm, distributed with 16 irrigation events. Tomato yield varied from 7.10 to 14.4kgm?2, with a WUE ranging from 19.1 to 38.9kgm?3. The irrigation system allowed a high yield levels and a low depth of water applied, as compared to seasonal ET crop estimated with Hargraves formula and with the literature data on irrigated tomato. Measurements were carried out on geo-referenced points to gather information on crop (crop yield, eighteen Vegetation indices, leaf area index) and on soil (spectroradiometric and traditional analysis). Eight VIs, out of nineteen ones analyzed, showed a significant relationship with georeferenced yield data; PVI maps seemed able to return the best response, before harvesting, to improve the knowledge of the area of cultivation and irrigation system. CropSense irrigation system reduced seasonal irrigation volumes. Some vegetation indexes were significantly correlated to tomato yield and well identify, a posteriori, crop area with low WUE; spectroradiometry can be a valuable tool to improve irrigated tomato field management.

Comparative evaluation of crop water use efficiency, economic analysis and net household profit simulation in arid Northwest China  

Science Journals Connector (OSTI)

Abstract Decreasing water availability for agricultural production has prompted researchers to focus on comparing and evaluating water use efficiency (WUE) of different crops in various water management strategies. A field survey was conducted to investigate the amount of irrigation water, inputs and yields of eight crops (spring wheat, maize, onion, cotton, hot pepper, sunflower, melons and fennel) grown under furrow irrigation systems in an arid region, Minqin county, Northwestern China (NWC). Previous publications reporting crop WUE were identified and major statistics of evapotranspiration (ET), yield (Y) and WUE were calculated for each crop. By comparing with literature reporting, the mean WUE of onion (8.71kgm?3), cotton (0.56kgm?3), sunflower seed (0.78kgm?3) and fennel (0.51kgm?3) grown in NWC were at the same high levels; while WUE of wheat (0.87kgm?3) and maize (1.17kgm?3) were slightly lower and WUE of hot pepper (2.68kgm?3) and melons (3.27kgm?3) were extremely low. Great potential of saving water could be achieved to realize increased or ideal WUE values for crops in NWC. The total net profit per household of cotton (1606.62$hh?1) was significantly larger and of onion (?3132.30$hh?1) significantly lower than that of other crops. Cotton, sunflower seed, melons and hot pepper had significantly higher crop production values per unit water than other crops, 0.39$m?3, 0.36$m?3, 0.32$m?3 and 0.31$m?3, respectively. The net household profits were significantly higher when excluding onion production for its extremely low price in 2011. With simulation based on different combinations of onion production and increase of migrant workers, the average net household profit could be optimized to provide benefits to local farmers and policy makers regarding income increase and rural policy design.

Winter wheat with subsurface drip irrigation (SDI): Crop coefficients, water-use estimates, and effects of SDI on grain yield and water use efficiency  

Science Journals Connector (OSTI)

Abstract Winter wheat (Triticum aestivum L.) production in the North China Plain (NCP) is threatened by insufficient water supply. Interest in microirrigation is increasing in the NCP, while data and guidance for microirrigation scheduling are lacking. An accurate estimation of actual crop evapotranspiration (ETa) is critical for appropriate water management. In this study, therefore, the \\{SIMDualKc\\} model was calibrated with the data from a three-season experiment, and \\{ETa\\} of winter wheat with subsurface drip irrigation (SDI) was estimated with the dual crop coefficient approach and stress adjustments described in the FAO-56 using the data of the other two treatments. The mean value of basal crop coefficient (Kcb) for the winter wheat at the initial-, mid-, and late-season growth stages over the three seasons was 0.25, 1.06, and 0.34, respectively. Over the three growing seasons, the \\{ETa\\} for subsurface drip-irrigated wheat with three irrigation treatments ranged from 393 to 449mm. The Kc-local (ETa/ETo) values for the winter wheat with SDI were 0.340.80, 0.911.11, and 0.410.98, respectively, at the initial-, mid-, and late-season growth stages. Results indicated that the procedure of the dual Kc approach and stress adjustments simulated \\{ETa\\} of the winter wheat reasonably well, with the average absolute error (AAE) of 0.36mmd?1, the root mean square error (RMSE) of 0.43mmd?1,the index of agreement (d) of 0.98, the NashSutcliffe efficiency (NSE) of 0.91, and the RMSE-observations standard deviation ratio (RSR) of 0.31. Discrepancy between the simulated and measured data was mainly attributed to the assumption of a uniform distribution of soil water around an emitter. Irrigation rates have significant effects on ETa, grain yield and WUE. Based on effects of irrigation rates on grain yield and WUE, irrigation schedule for optimum yield and WUE was developed for winter wheat. It was estimated that grain yield and WUE of winter wheat with the optimum irrigation schedule was 7780kgha?1 and 1.83kgm?3, respectively. The simulated results can be used as a reference for irrigation schedule and water management for winter wheat in the NCP.

Basic Engineering Research for D and D of R Reactor Storage Pond Sludge: Electrokinetics, Carbon Dioxide Extraction, and Supercritical Water Oxidation  

SciTech Connect

Large quantities of mixed low level waste (MLLW) that fall under the Toxic Substances Control Act (TSCA) exist and will continue to be generated during D and D operations at DOE sites across the country. The standard process for destruction of MLLW is incineration, which has an uncertain future. The extraction and destruction of PCBs from MLLW was the subject of this research Supercritical Fluid Extraction (SFE) with carbon dioxide with 5% ethanol as cosolvent and Supercritical Waster Oxidation (SCWO) were the processes studied in depth. The solid matrix for experimental extraction studies was Toxi-dry, a commonly used absorbent made from plant material. PCB surrogates were 1.2,4-trichlorobenzene (TCB) and 2-chlorobiphenyl (2CBP). Extraction pressures of 2,000 and 4,000 psi and temperatures of 40 and 80 C were studied. Higher extraction efficiencies were observed with cosolvent and at high temperature, but pressure little effect. SCWO treatment of the treatment of the PCB surrogates resulted in their destruction below detection limits.

BASIC ENGINEERING RESEARCH FOR D&D OF R REACTOR STORAGE POND SLUDGE: ELECTROKINETICS, CARBON DIOXIDE EXTRACTION, AND SUPERCRITICAL WATER OXIDATION  

SciTech Connect

Large quantities of mixed low level waste (MLLW) that fall under the Toxic Substances Control Act (TSCA) exist and will continue to be generated during D&D operations at DOE sites across the country. Currently, the volume of these wastes is approximately 23,500 m3, and the majority of these wastes (i.e., almost 19,000 m3) consist of PCBs and PCB-contaminated materials. Further, additional PCB-contaminated waste will be generated during D&D operations in the future. The standard process for destruction of this waste is incineration, which generates secondary waste that must be disposed, and the TSCA incinerator at Oak Ridge has an uncertain future. Beyond incineration, no proposed process for the recovery and/or destruction of these persistent pollutants has emerged as the preferred choice for DOE cleanup. The main objective of the project was to investigate and develop a deeper understanding of the thermodynamic and kinetic reactions involved in the extraction and destruction of polychlorinated biphenyls (PCBs) from low-level mixed waste solid matrices in order to provide data that would permit the design of a combined-cycle extraction/destruction process. The specific research objectives were to investigate benign dense-fluid extraction with either carbon dioxide (USC) or hot water (CU), followed by destruction of the extracted PCBs via either electrochemical (USC) or hydrothermal (CU) oxidation. Two key advantages of the process are that it isolates and concentrates the PCBs from the solid matrices (thereby reducing waste volume greatly and removing the remaining low-level mixed waste from TSCA control), and little, if any, secondary solvent or solid wastes are generated. This project was a collaborative effort involving the University of South Carolina (USC), Clemson University (CU), and Westinghouse Savannah River Company (WSRC) (including the Savannah River Technology Center, Facilities Decommissioning Division and Regulatory Compliance). T he project was directed and coordinated by the South Carolina Universities Research and Education Foundation (SCUREF), a consortium of the four public research universities in South Carolina. The original plan was to investigate two PCB extraction processes (supercritical carbon dioxide and hot, pressurized water) and two PCB destruction processes (electrochemical oxidation and hydrothermal oxidation). However, at approximately the mid-point of the three year project, it was decided to focus on the more promising extraction process (supercritical carbon dioxide) and the more promising destruction process (supercritical water oxidation). This decision was taken because the investigation of two processes simultaneously by each university was stretching resources too thin, and because the electrochemical oxidation process needed more concentrated research before it would be ready for application to PCB destruction. The solid matrix chosen for experimental work was Toxi-dry, a commonly used adsorbent made from plant material that is used in cleanup of spills and/or liquid solvents. The Toxi-dry was supplied by the research team member from the Facilities Decommissioning Division, WSRC. This adsorbent is a major component of job control waste.

Basic Engineering Research for D&D of R. Reactor Storage Pond Sludge: Electrokinetics, Carbon Dioxide Extraction, and Supercritical Water Oxidation  

SciTech Connect

Collaborating researchers at the University of South Carolina (USC), Clemson University (CU), and the Savannah River Site (SRS) are investigating the fundamentals of a combined extraction and destruction process for the decontamination and decommissioning (D&D) of PCB-contaminated materials as found at DOE sites. Currently, the volume of PCBs and PCB contaminated wastes at DOE sites nationwide is approximately 19,000 m3. While there are a number of existing and proposed processes for the recovery and/or destruction of these persistent 4 pollutants, none has emerged as the preferred choice. Therefore, this research focuses on combining novel processes to solve the problem. The research objectives are to investigate benign dense-fluid extraction with either carbon dioxide (USC) or hot water (CU), followed by destruction of the extracted PCBs via either electrochemical (USC) or hydrothermal (CU) oxidation. Based on the results of these investigations, a combined extraction and destruction process that incorporates the most successful elements of the various processes will be recommended for application to contaminated DOE sites.

Growth, grain yield, and water use efficiency of rain-fed spring hybrid millet (Setaria italica) in plastic-mulched and unmulched fields  

Science Journals Connector (OSTI)

Abstract In order to analyze the effect of plastic mulching on water use efficiency of spring hybrid millet (Setaria italica), field experiments were conducted during the 2012 growing season, at an experimental station located in a semi-arid region of North China. Four treatments were applied: (i) plastic mulching of ridges and furrow sowing (T1), (ii) ridges and furrows without plastic mulch (T0), (iii) flat soil with plastic mulch (A1), and (iv) flat soil with no plastic mulch (A0) (control). Dynamics of soil moisture and soil temperature, together with crop growth, were monitored continuously in both mulched and unmulched fields. Changes in water consumption, soil temperature, and plant growth and development were analyzed. Results indicated that plastic mulching produced a 25-day advance in emergence of each growth stage. Soil temperature at 015cm depth increased by 1.25C and 0.84C under mulched treatments A1 and T1, respectively, while soil water content at a depth of 010cm increased by 1.42% and 1.29% in the same treatments. Leaf area index and plant height were also significantly higher in plastic-mulched treatments, except in later growth stages. Because plastic mulching improved tiller and ear numbers significantly, grain yield increased by 13.25% and 6.64%, in Al and T1 treatments, respectively. Water use efficiency at yield levels of plastic-mulched A1 and T1 plots was 24.44% and 3.6% higher than in unmulched flat and furrowed plots, respectively. Plastic mulching significantly reduced water consumption, retained soil water content, and increased soil temperature, to promote spring hybrid millet germination, and increased tiller numbers, and consequently, aboveground dry matter; it eventually significantly improved grain yield and water use efficiency. Plastic film mulching produced greater grain yield, water use efficiency, and benefits when used in flat planting patterns.

Basic hydrodynamic aspects of a solar energy based desalination process  

SciTech Connect

The theoretical feasibility of a solar energy based desalination scheme is analyzed in this study. The proposed scheme exploits the vapor pressure difference between fluids of different salinities and temperatures to produce fresh water from seawater. The scheme`s basic components are a seawater column, an injection pipe heated on top through a heat exchanger loop, a withdrawal pipe, a vacuum chamber filled with vapour, and a fresh water column cooled on top where vapour condenses into fresh water. A mathematical model was developed to simulate unsteady mass, heat and solute transfer during the desalination process. The governing equations were integrated numerically in space and time through a finite difference technique. The numerical simulations considered both steady-state and time dependent heat sources. The numerical results proved the theoretical feasibility of the proposed desalination scheme. However, the presence of an unsteady heat source, typical to solar energy based schemes, may lead to an unstable density profile in the water column and reduce the scheme efficiency if not properly controlled. 16 refs., 8 figs.

USING LIGA BASED MICROFABRICATION TO IMPROVE OVERALL HEAT TRANSFER EFFICIENCY OF PRESSURIZED WATER REACTOR: I. Effects of Different Micro Pattern on Overall Heat Transfer.  

SciTech Connect

The Pressurized Water Reactors (PWRs in Figure 1) were originally developed for naval propulsion purposes, and then adapted to land-based applications. It has three parts: the reactor coolant system, the steam generator and the condenser. The Steam generator (a yellow area in Figure 1) is a shell and tube heat exchanger with high-pressure primary water passing through the tube side and lower pressure secondary feed water as well as steam passing through the shell side. Therefore, a key issue in increasing the efficiency of heat exchanger is to improve the design of steam generator, which is directly translated into economic benefits. The past research works show that the presence of a pin-fin array in a channel enhances the heat transfer significantly. Hence, using microfabrication techniques, such as LIGA, micro-molding or electroplating, some special microstructures can be fabricated around the tubes in the heat exchanger to increase the heat-exchanging efficiency and reduce the overall size of the heat-exchanger for the given heat transfer rates. In this paper, micro-pin fins of different densities made of SU-8 photoresist are fabricated and studied to evaluate overall heat transfer efficiency. The results show that there is an optimized micro pin-fin configuration that has the best overall heat transfer effects.

A Synergistic Combination of Advanced Separation and Chemical Scale Inhibitor Technologies for Efficient Use of Imparied Water As Cooling Water in Coal-based Power Plants  

SciTech Connect

Nalco Company is partnering with Argonne National Laboratory (ANL) in this project to jointly develop advanced scale control technologies that will provide cost-effective solutions for coal-based power plants to operate recirculating cooling water systems at high cycles using impaired waters. The overall approach is to use combinations of novel membrane separations and scale inhibitor technologies that will work synergistically, with membrane separations reducing the scaling potential of the cooling water and scale inhibitors extending the safe operating range of the cooling water system. The project started on March 31, 2006 and ended in August 30, 2010. The project was a multiyear, multi-phase project with laboratory research and development as well as a small pilot-scale field demonstration. In Phase 1 (Technical Targets and Proof of Concept), the objectives were to establish quantitative technical targets and develop calcite and silica scale inhibitor chemistries for high stress conditions. Additional Phase I work included bench-scale testing to determine the feasibility of two membrane separation technologies (electrodialysis ED and electrode-ionization EDI) for scale minimization. In Phase 2 (Technology Development and Integration), the objectives were to develop additional novel scale inhibitor chemistries, develop selected separation processes, and optimize the integration of the technology components at the laboratory scale. Phase 3 (Technology Validation) validated the integrated system's performance with a pilot-scale demonstration. During Phase 1, Initial evaluations of impaired water characteristics focused on produced waters and reclaimed municipal wastewater effluents. Literature and new data were collected and evaluated. Characteristics of produced waters vary significantly from one site to another, whereas reclaimed municipal wastewater effluents have relatively more uniform characteristics. Assessment to date confirmed that calcite and silica/silicate are two common potential cycle-limiting minerals for using impaired waters. For produced waters, barium sulfate and calcium sulfate are two additional potential cycle-limiting minerals. For reclaimed municipal wastewater effluents, calcium phosphate scaling can be an issue, especially in the co-presence of high silica. Computational assessment, using a vast amount of Nalco's field data from coal fired power plants, showed that the limited use and reuse of impaired waters is due to the formation of deposit caused by the presence of iron, high hardness, high silica and high alkalinity in the water. Appropriate and cost-effective inhibitors were identified and developed - LL99B0 for calcite and gypsum inhibition and TX-15060 for silica inhibition. Nalco's existing dispersants HSP-1 and HSP-2 has excellent efficacy for dispersing Fe and Mn. ED and EDI were bench-scale tested by the CRADA partner Argonne National Laboratory for hardness, alkalinity and silica removal from synthetic make-up water and then cycled cooling water. Both systems showed low power consumption and 98-99% salt removal, however, the EDI system required 25-30% less power for silica removal. For Phase 2, the EDI system's performance was optimized and the length of time between clean-in-place (CIP) increased by varying the wafer composition and membrane configuration. The enhanced EDI system could remove 88% of the hardness and 99% of the alkalinity with a processing flux of 19.2 gal/hr/m{sup 2} and a power consumption of 0.54 kWh/100 gal water. Bench tests to screen alternative silica/silicate scale inhibitor chemistries have begun. The silica/silicate control approaches using chemical inhibitors include inhibition of silicic acid polymerization and dispersion of silica/silicate crystals. Tests were conducted with an initial silica concentration of 290-300 mg/L as SiO{sub 2} at pH 7 and room temperature. A proprietary new chemistry was found to be promising, compared with a current commercial product commonly used for silica/silicate control. Additional pilot cooling tower testing confirmed

LED Lighting Basics LED Lighting Basics LED Lighting Basics August 16, 2013 - 10:07am Addthis Light-emitting diodes (LEDs) are light sources that differ from more traditional sources of light in that they are semiconductor devices that produce light when an electrical current is applied. Applying electrical current causes electrons to flow from the positive side of a diode to the negative side. Then, at the positive/negative junction of the diode, the electrons slow down to orbit at a lower energy level. The electrons emit the excess energy as photons of light. LEDs are often used as small indicator lights on various electronic devices. Because of their long life, durability, and efficiency, LEDs are becoming more common in residential, commercial, and outdoor area lighting

The ultraviolet light in turn interacts with special blends of phosphors coating the interior surface of the fluorescent lamp tube that efficiently converts the invisible light into useful white light. Fluorescent lamps require a special power supply called a ballast that is needed to regulate lamp operating current and provide a compatible start-up voltage. Electronic ballasts perform the same function as a magnetic ballast but outperform the outdated magnetic products by operating at a very high frequency that eliminates flicker and noise while

Silicon Cell Basics Silicon Cell Basics Photovoltaic Silicon Cell Basics August 20, 2013 - 2:19pm Addthis Silicon-used to make some the earliest photovoltaic (PV) devices-is still the most popular material for solar cells. Silicon is also the second-most abundant element in the Earth's crust (after oxygen). However, to be useful as a semiconductor material in solar cells, silicon must be refined to a purity of 99.9999%. In single-crystal silicon, the molecular structure-which is the arrangement of atoms in the material-is uniform because the entire structure is grown from the same crystal. This uniformity is ideal for transferring electrons efficiently through the material. To make an effective PV cell, however, silicon has to be "doped" with other elements to make n-type and p-type layers.

An environment friendly and efficient lignite-fired power generation process based on a boiler with an open pulverizing system and the recovery of water from mill-exhaust  

Science Journals Connector (OSTI)

Abstract This paper advances a novel lignite-fired power generation process based on a OPSB (boiler with an open pulverizing system) and the recovery of water from mill-exhaust after the comprehensive analysis of the open pulverizing system used for high-moisture coals and heat/water recovery from boiler exhaust. Then, the thermal calculation method that applies to OPSB is presented based on heat and mass balance analyses of the boiler. Finally, an efficient unit applying the OPSB process is compared with a conventional 600MW lignite-fired power unit, and the performance of the efficient unit is calculated and discussed in detail. The results show that the efficient unit not only yields a notable increase in the boiler's (2.6%) and the power plant's (1.3%) thermal efficiency but also provides a remarkable advantage in water recovery due to the mass of water vapor concentrated in mill-exhaust. In the efficient unit, the volume fraction of water vapor in mill-exhaust reaches 34%, the water reclaimed from mill-exhaust is so much that a lignite-fired power plant with zero water consumption can be expected, while the pollutant emissions can be reduced in proportion to the increase in boiler thermal efficiency.

Analyzing the efficiency of a heat pump assisted drain water heat recovery system that uses a vertical inline heat exchanger  

Science Journals Connector (OSTI)

Abstract The purpose of the present study is to accumulate knowledge on how a drain water heat recovery system using a vertical inline heat exchanger and a heat pump performs under different drain water flow profile scenarios. Investigating how the intermittent behavior of the drain water influences the performance for this type of system is important because it gives insight on how the system will perform in a real life situation. The scenarios investigated are two 24h drain water flow rate schedules and one shorter schedule representing a three minute shower. The results from the present paper add to the knowledge on how this type of heat recovery system performs in a setting similar to a multi-family building and how sizing influences the performance. The investigation shows that a heat recovery system of this type has the possibility to recover a large portion of the available heat if it has been sized to match the drain water profile. Sizing of the heat pump is important for the system performance; sizing of the storage tank is also important but not as critical.

Multilayer films of indium tin oxide/TiO2 codoped with vanadium and nitrogen for efficient photocatalytic water splitting  

Science Journals Connector (OSTI)

TiO22 films codoped with V cations and N anions were synthesised by RF-magnetron sputtering. The incorporation of V and N in TiO2 lattice produces isolated energy levels near the conduction and valence bands, respectively, causing an effective narrowing of the band gap to 2.5 eV. Recombination of photo-charges was reduced by depositing multilayer films of indium tin oxide (ITO)/V-N-codoped TiO2 with different numbers of bilayers. In multilayer structure, the generated photoelectrons, travelling into TiO2 film of limited thickness, rapidly enter the space charge interface of the ITO/TiO2 films from where they are instantaneously injected into the ITO layer and then removed towards the cathode. The synergic effects created by band narrowing and enhanced charge separation by using codoping and multilayer structure strategy in TiO2 generate higher photocurrent for water splitting under visible light which definitely exceeds that obtained by doping TiO2 with a single, V or N, element.

NREL: Learning - Geothermal Heat Pump Basics  

NLE Websites -- All DOE Office Websites (Extended Search)

Heat Pump Basics Heat Pump Basics Photo of the West Philadelphia Enterprise Center. The West Philadelphia Enterprise Center uses a geothermal heat pump system for more than 31,000 square feet of space. Geothermal heat pumps take advantage of the nearly constant temperature of the Earth to heat and cool buildings. The shallow ground, or the upper 10 feet of the Earth, maintains a temperature between 50° and 60°F (10°-16°C). This temperature is warmer than the air above it in the winter and cooler in the summer. Geothermal heat pump systems consist of three parts: the ground heat exchanger, the heat pump unit, and the air delivery system (ductwork). The heat exchanger is a system of pipes called a loop, which is buried in the shallow ground near the building. A fluid (usually water or a mixture of

Fruit Yield and Quality, and Irrigation Water Use Efficiency of Summer Squash Drip-Irrigated with Different Irrigation Quantities in a Semi-Arid Agricultural Area  

Science Journals Connector (OSTI)

Abstract Fruit yield, yield components, fruit mineral content, total phenolic content, antioxidant activity and irrigation water use efficiency (IWUE) of summer squash responses to different irrigation quantities were evaluated with a field study. Irrigations were done when the total evaporated water from a Class A pan was about 30 mm. Different irrigation quantities were adjusted using three different plant-pan coefficients (Kcp, 100% (Kcp1), 85% (Kcp2) and 70% (Kcp3)). Results indicated that lower irrigation quantities provided statistically lower yield and yield components. The highest seasonal fruit yield (80.0 t ha?1) was determined in the Kcp1 treatment, which applied the highest volume of irrigation water (452.9 mm). The highest early fruit yield, average fruit weight and fruit diameter, length and number per plant were also determined in the Kcp1 treatment, with values of 7.25 t ha?1, 264.1 g, 5.49 cm, 19.95 cm and 10.92, respectively. Although the IWUE value was the highest in the Kcp1 treatment (176.6 kg ha?1 mm?1), it was statistically similar to the value for Kcp3 treatment (157.1 kg ha?1 mm?1). Total phenolic content and antioxidant activity of fruits was higher in the Kcp1 (44.27 ?g gallic acid equivalents (GAE) mg?1 fresh sample) and in the Kcp2 (84.75%) treatments, respectively. Major (Na, N, P, K, Ca, Mg and S) and trace (Fe, Cu, Mn, Zn and B) mineral contents of squash fruits were the highest in the Kcp2 treatment, with the exception of P, Ca and Cu. Mineral contents and total phenolic content were significantly affected by irrigation quantities, but antioxidant activity was not affected. It can be concluded that the Kcp1 treatment was the most suitable for achieving higher yield and IWUE. However, the Kcp2 treatment will be the most suitable due to the high fruit quality and relatively high yield in water shortage conditions.

Conveyance and Filter Basics Conveyance and Filter Basics Microhydropower Conveyance and Filter Basics August 16, 2013 - 3:53pm Addthis Before water enters the turbine or waterwheel of a microhydropower system, it is funneled through a series of components that control its flow and filter out debris. These components include the headrace, forebay, and water conveyance (or channel, pipeline, or penstock). The headrace is a waterway that runs parallel to the water source. A headrace is sometimes necessary for hydropower systems when insufficient head, or vertical drop, is provided and is usually constructed of cement or masonry. The headrace leads to the forebay, which also is made of concrete or masonry. It functions as a settling pond for large debris that would otherwise flow into the system and damage the turbine.

Light Water Reactor Sustainability Program BWR High-Fluence Material Project: Assessment of the Role of High-Fluence on the Efficiency of HWC Mitigation on SCC Crack Growth Rates  

SciTech Connect

As nuclear power plants age, the increasing neutron fluence experienced by stainless steels components affects the materials resistance to stress corrosion cracking and fracture toughness. The purpose of this report is to identify any new issues that are expected to rise as boiling water reactor power plants reach the end of their initial life and to propose a path forward to study such issues. It has been identified that the efficiency of hydrogen water chemistry mitigation technology may decrease as fluence increases for high-stress intensity factors. This report summarizes the data available to support this hypothesis and describes a program plan to determine the efficiency of hydrogen water chemistry as a function of the stress intensity factor applied and fluence. This program plan includes acquisition of irradiated materials, generation of material via irradiation in a test reactor, and description of the test plan. This plan offers three approaches, each with an estimated timetable and budget.

Effects of Phosphorus Application in Different Soil Layers on Root Growth, Yield, and Water-Use Efficiency of Winter Wheat Grown Under Semi-Arid Conditions  

Science Journals Connector (OSTI)

Abstract Deep phosphorus application can be a usefull measure to improve crops performance in semi-arid regions, but more knowledge of both its general effects and effects on specific crops is required to optimize treatments. Thus, the aims of this study were to evaluate the effects of phosphorus (P) application at different soil layers on root growth, grain yield, and water-use efficiency (WUE) of winter wheat grown on the semi-arid Loess Plateau of China and to explore the relationship between root distribution and grain yield. The experiment consisted of four P treatments in a randomized complete block design with three replicates and two cultivars: one drought-sensitive (Xiaoyan 22, XY22) and one drought-tolerant (Changhan 58, CH58). The four P treatments were no P (control, CK), surface P (SP), deep P (DP), and deep-band P application (DBP). CH58 produced larger and deeper root systems, and had higher grain yields and WUE, under the deep P treatments (DP and DBP) than under SP, clearly showing that deep P placement had beneficial effects on the drought-tolerant cultivar. In contrast, the grain yield and root growth of XY22 did not differ between DP or DBP and SP treatments. Further, root dry weight (RW) and root length (RL) in deep soil layer (30-100 cm) were closely positively correlated with grain yield and WUE of CH58 (but not XY22), highlighting the connections between a well-developed subsoil root system and both high grain yield and WUE for the drought-tolerant cultivar. WUE correlated strongly with grain yield for both cultivars (r=0.94, P<0.001). In conclusion, deep application of P fertilizer is a practical and feasible means of increasing grain yield and WUE of rainfed winter wheat in semi-arid regions, by promoting deep root development of drought-tolerant cultivars.

Distributed Energy Basics Distributed Energy Basics Photo of transmission towers and lines extending for miles towards a pink sunset in the distance. Distributed energy technologies can relieve transmission bottlenecks by reducing the amount of electricity that must be sent long distances down high-voltage power lines. Distributed energy refers to a variety of small, modular power-generating technologies that can be combined with load management and energy storage systems to improve the quality and/or reliability of the electricity supply. They are "distributed" because they are placed at or near the point of energy consumption, unlike traditional "centralized" systems, where electricity is generated at a remotely located, large-scale power plant and then transmitted down power lines to the consumer.

Characterization and Alteration of Wettability States of Alaskan Reserviors to Improve Oil Recovery Efficiency (including the within-scope expansion based on Cyclic Water Injection - a pulsed waterflood for Enhanced Oil Recovery)  

SciTech Connect

Numerous early reports on experimental works relating to the role of wettability in various aspects of oil recovery have been published. Early examples of laboratory waterfloods show oil recovery increasing with increasing water-wetness. This result is consistent with the intuitive notion that strong wetting preference of the rock for water and associated strong capillary-imbibition forces gives the most efficient oil displacement. This report examines the effect of wettability on waterflooding and gasflooding processes respectively. Waterflood oil recoveries were examined for the dual cases of uniform and non-uniform wetting conditions. Based on the results of the literature review on effect of wettability and oil recovery, coreflooding experiments were designed to examine the effect of changing water chemistry (salinity) on residual oil saturation. Numerous corefloods were conducted on reservoir rock material from representative formations on the Alaska North Slope (ANS). The corefloods consisted of injecting water (reservoir water and ultra low-salinity ANS lake water) of different salinities in secondary as well as tertiary mode. Additionally, complete reservoir condition corefloods were also conducted using live oil. In all the tests, wettability indices, residual oil saturation, and oil recovery were measured. All results consistently lead to one conclusion; that is, a decrease in injection water salinity causes a reduction in residual oil saturation and a slight increase in water-wetness, both of which are comparable with literature observations. These observations have an intuitive appeal in that water easily imbibes into the core and displaces oil. Therefore, low-salinity waterfloods have the potential for improved oil recovery in the secondary recovery process, and ultra low-salinity ANS lake water is an attractive source of injection water or a source for diluting the high-salinity reservoir water. As part of the within-scope expansion of this project, cyclic water injection tests using high as well as low salinity were also conducted on several representative ANS core samples. These results indicate that less pore volume of water is required to recover the same amount of oil as compared with continuous water injection. Additionally, in cyclic water injection, oil is produced even during the idle time of water injection. It is understood that the injected brine front spreads/smears through the pores and displaces oil out uniformly rather than viscous fingering. The overall benefits of this project include increased oil production from existing Alaskan reservoirs. This conclusion is based on the performed experiments and results obtained on low-salinity water injection (including ANS lake water), vis-a-vis slightly altering the wetting conditions. Similarly, encouraging cyclic water-injection test results indicate that this method can help achieve residual oil saturation earlier than continuous water injection. If proved in field, this would be of great use, as more oil can be recovered through cyclic water injection for the same amount of water injected.

Effect of rooting depth, plant density and planting date on maize (Zea mays L.) yield and water use efficiency in semi-arid Zimbabwe: Modelling with AquaCrop  

Science Journals Connector (OSTI)

Abstract Under low and poorly distributed rainfall higher food production can be achieved by increasing crop water use efficiency (WUE) through optimum soil fertility management and selection of deep-rooting cultivars, appropriate plant density and planting dates. We explored AquaCrop's applicability in selecting adaptive practices for improving maize yield and WUE under rainfed smallholder farming in semi-arid Zimbabwe. AquaCrop was first tested using field measurements without calibration. The model was subsequently applied to estimate the effect of effective rooting depth (ERD), plant density and planting date on maize yield. Simulations were done with daily rainfall data for 25 seasons. During model testing AquaCrop simulated canopy cover development well and simulated biomass accumulation showed good agreement with measured values. The model overestimated soil water, and observed final biomass and grain yield were 96 and 92% of simulated values, respectively. Model application showed that increasing ERD from 0.40m at 32,500plantsha?1 to 0.60m at 44,400plantsha?1 increased grain yield from 6.0 to 7.8tha?1, biomass water use efficiency by 20.5%, grain water use efficiency by 23.6% and transpiration water use efficiency by 26.8%. At 0.60 and 0.80m ERD and 44,400plantsha?1, biomass and grain yield, and WUE, were similar. Drainage below the rootzone was ?40% of non-productive water losses in normal and wet seasons whilst soil evaporation contributed 47% in dry seasons at 0.80m ERD. To improve yield and WUE, we recommend: incorporation of deep-rooting legumes, deeper-rooting cultivars (?0.60m effective rooting depth) and practices that improve ERD, a plant density of 44,400plantsha?1; and practices that reduce soil evaporation e.g. mulching and addition of organic fertilisers to improve soils available water capacity and enhance response to mineral fertilisers. Further research should include field testing of results from this study with farmers.

Just the Basics: Diesel Engine  

NLE Websites -- All DOE Office Websites (Extended Search)

Today's direct-injection diesel Today's direct-injection diesel engines are more rugged, powerful, durable, and reliable than gasoline engines, and use fuel much more efficiently, as well. Diesel Engines Yesterday, Today, and Tomorrow Diesels are workhorse engines. That's why you find them powering heavy- duty trucks, buses, tractors, and trains, not to mention large ships, bulldozers, cranes, and other construction equipment. In the past, diesels fit the stereotype of muscle-bound behe- moths. They were dirty and sluggish, smelly and loud. That image doesn't apply to today's diesel engines, however, and tomorrow's diesels will show even greater improvements. They will be even more fuel efficient, more flexible in the fuels they can use, and also much cleaner in emissions. How Diesel Engines Work

Chapter 3 - Google Hacking Basics  

Science Journals Connector (OSTI)

Publisher Summary This chapter focuses on the basics of Google hacking and the functionality of the directory listings that can be used to locate specific files and directories. Google cache is a powerful tool in the hands of an advanced user. It can be used to locate old versions of pages that may expose information that normally would be unavailable to the casual user. The cache can be used to highlight terms in the cached version of a page, even if the terms were not used as part of the query to find that page. An advanced Google user will always pay careful attention to the details contained in the cached page's header, since there can be important information about the date the page was crawled, the terms that were found in the search, whether the cached page contains external images, links to the original page, and the text of the URL used to access the cached version of the page. Directory listings contain a great deal of information that is interesting from a security perspective. The directory listings can be used to determine specific information about the software installed on a server. Traversal techniques can be used to locate information that is often outside the piercing gaze of Google's crawlers. The chapter explores some specific techniques including directory traversal, incremental substitution, and extension walking.
