Eisenbeis, Supt. of Conservation LIGHTNING Because we are so rapt up with our modern inventions, we forget that primitive man, ages before the beginnings of civilization, made one of the greatest discoveries of all time -- the use of fire. However, for thousands of years before he learned to kindle his own fires by friction or by striking sparks from flint, he snatched flaming firebrands from forest fires started by lightning. These he carried away and carefully fed with dry wood, year in and year out, to warm his cave, frighten away wild beasts and cook his food. Around the world, in every year, countless thousands of fires are started by lightning.

Physics of ball lightning  

Science Journals Connector (OSTI)

An up to date description of the state of the ball lightning problem is given. The properties of ball lightning have been derived from a statistical treatment of thousands of observations. The experimental modeling of ball lightning as a whole is reviewed. The analysis leads to the conclusion that ball lightning has a rigid skeleton; a spotted structure of its glowing follows from a large difference between the radiative and mean temperatures of the ball lightning. Ball lightning is a many-sided phenomenon, and therefore has a number of analogs which are related to its separate properties and which can be modeled. The mechanical, gas-dynamical, energetic radiative and electrical processes of ball lightning are analyzed on the basis of such analogs and recent scientific information. According to this analysis, the substance composing ball lightning has a sparse fractal structure, similar to an aerogel, with the density of a gas and the behavior of a solid or liquid. The best model resembling the ball lightning structure is a knot of fractal fibers. The glowing of ball lightning is created by many thermal waves that propagate along separate fibers, use the surface energy of the structure, and form glowing hot zones with a temperature of about 2000 K. A number of models considered allow us to study the nature of ball lightning in detail.

Hydrodynamic analysis of AUV underwater docking with a cone-shaped dock under ocean currents  

Science Journals Connector (OSTI)

Abstract This paper investigates the hydrodynamics issues that are associated with \\{AUVs\\} (autonomous underwater vehicles) as they approach a cone-shaped dock, which is proposed by most AUV docking systems for the AUV?s protection and simplification. However, this docking system is more sensitive to the hydrodynamic interactions between the dock and the ocean currents. The purpose is to exploit the hydrodynamic susceptibility in AUV docking with the dock and to identify a probable design for AUV control during docking. To achieve this purpose, numerical simulations of an AUV docking with a dock are conducted based on the dynamic mesh method. This paper illustrates the numerical methodology for AUV docking simulation. To increase the accuracy of the numerical simulation, turbulence models and grid-dependence problems are first studied. Then, 3D (three-dimensional) numerical simulations show the dependence of the AUV fluid forces near the dock on various velocities, accelerations, dock shapes, gliding modes, cross currents from several directions and rudder angles. The hydrodynamic behaviors of an AUV docking with a dock are obtained, which provide helpful suggestions for successful docking.

Lightning prevention systems for paper mills  

SciTech Connect (OSTI)

Paper mills are increasingly relying on sensitive electronic equipment to control their operations. However, the sensitivity of these devices has made mills vulnerable to the effects of lightning strokes. An interruption in the power supply or the destruction of delicate microcircuits can have devastating effects on mill productivity. The authors discuss how lightning strokes can be prevented by a Dissipation Array system (DAS). During the past 17 years, the concept has been applied to a host of applications in regions with a high incidence of lightning activity. With nearly 700 systems now installed, more than 4000 system-years of history have been accumulated. Areas as large as 1 km{sup 2} and towers as high as 2000 ft have been protected and completely isolated from lightning strokes. There have been very few failures, and in every case, the cause of the failure was determined and corrected.

The Lightning Arrestor Connector (LAC), part M, presented opportunities to improve the processes used to fabricate LACs. The A## LACs were the first production LACs produced at the KCP, after the product was transferred from Pinnellas. The new LAC relied on the lessons learned from the A## LACs; however, additional improvements were needed to meet the required budget, yield, and schedule requirements. Improvement projects completed since 2001 include Hermetic Connector Sealing Improvement, Contact Assembly molding Improvement, development of a second vendor for LAC shells, general process improvement, tooling improvement, reduction of the LAC production cycle time, and documention of the LAC granule fabrication process. This report summarizes the accomplishments achieved in improving the LAC Production Readiness.

Augmenting Satellite Precipitation Estimation with Lightning Information  

SciTech Connect (OSTI)

We have used lightning information to augment the Precipitation Estimation from Remotely Sensed Imagery using an Artificial Neural Network - Cloud Classification System (PERSIANN-CCS). Co-located lightning data are used to segregate cloud patches, segmented from GOES-12 infrared data, into either electrified (EL) or non-electrified (NEL) patches. A set of features is extracted separately for the EL and NEL cloud patches. The features for the EL cloud patches include new features based on the lightning information. The cloud patches are classified and clustered using self-organizing maps (SOM). Then brightness temperature and rain rate (T-R) relationships are derived for the different clusters. Rain rates are estimated for the cloud patches based on their representative T-R relationship. The Equitable Threat Score (ETS) for daily precipitation estimates is improved by almost 12% for the winter season. In the summer, no significant improvements in ETS are noted.

Thunderstorm and Lightning Studies using the FORTE Optical Lightning System (FORTE/OLS)  

SciTech Connect (OSTI)

Preliminary observations of simultaneous RF and optical emissions from lightning as seen by the FORTE spacecraft are presented. RF/optical pairs of waveforms are routinely collected both as individual lightning events and as sequences of events associated with cloud-to-ground (CG) and intra-cloud (IC) flashes. CG pulses can be distinguished from IC pulses based on the properties of the RF and optical waveforms, but mostly based on the associated RF spectrograms. The RF spectrograms are very similar to previous ground-based VHF observations of lightning and show signatures associated with return strokes, stepped and dart leaders, and attachment processes,. RF emissions are observed to precede the arrival of optical emissions at the satellite by a mean value of 280 microseconds. The dual phenomenology nature of these observations are discussed in terms of their ability to contribute to a satellite-based lightning monitoring mission.

Advanced lightning location interferometer. Final report  

SciTech Connect (OSTI)

In January, 1994, New Mexico Institute for Mining and Technology (NM Tech) was commissioned by Los Alamos National Laboratories (LANL) to develop a three-axis interferometric lightning mapping system to be used in determining the source of certain frequency-dispersed pulse pairs which had been detected by spaceborne sensors. The existing NM Tech VHF Lightning Interferometer was a two axis system operating at 274 MHz with 6 MHz bandwidth. The third axis was to be added to refine estimates of the elevation angle to distant RF sources in that band. The system was to be initially deployed in support of an Air Force Technical Applications Center (AFTAC) effort planned for the Kennedy Space Center/Cape Canaveral AFS area in June-July of 1994. The project was, however, postponed until September of 1994. The interferometer was set up and operated at KSC near the Lightning Detection and Ranging (LDAR) central station. The initial setup was in two-axis configuration, and the third (vertical) axis was added at about mid-project. Though the storms were reduced in frequency and severity over what one would expect in mid-summer, several good data sets were obtained and delivered to AFTAC.

Lightning activity on Titan: can Cassini detect it?  

Science Journals Connector (OSTI)

Although no lightning discharges were observed during the Voyager 1 flyby of Titan, this lack of evidence does not rule out the existence of lightning phenomena which could be detected by the Radio and Plasma Wave Science (RPWS) instrument on board of the Cassini spacecraft. The existence of lightning or other electromagnetic discharges has been suggested to explain the formation of hydrocarbons and nitriles in the context of Titan's complex organic chemistry. Although thunderclouds may be a rare phenomenon in Titan's lower atmosphere, recent investigations show that such clouds may cause temporary maximum electrical fields in the order of 2106Vm?1 sufficient to initiate 20 km long Earth-like cloud-to-ground type 2 lightning strokes. Since such clouds are likely to be correlated with strong convection near the subsolar point, we expect possible lightning flashes to occur only on the dayside. Recent telescopic infrared observations have detected localized, high, short-lived clouds on Titan. We have calculated the flash characteristics, frequency spectrum, maximum spectral energy and the electromagnetic energy radiated into the troposphere by using a wave guide model of lightning currents for Titan's lightning strokes. Our study indicates that cloud-to-ground lightning strokes on Titan would be comparable with so-called type 2 lightning strokes on Earth. Their total radiated energy to the far field could be about 130 kJ and their maximum energy at a frequency of about 4 kHz. In order to estimate the capability of the Cassini/RPWS instrument to detect lightning discharges during several close Titan flybys, we distinguish the atmospheric regions, where the propagation of electromagnetic waves is unperturbed or where it is impossible. We found that the Cassini/RPWS instrument should be able to detect electromagnetic signals generated from a representative cloud-to-ground lightning stroke in Titan's lower atmosphere in a frequency range above 500 kHz or 1 \\{MHz\\} up to 200 Titan radii away. We suggest that for the search of lightning signals the RPWS high-frequency receiver HF2 with its H2-1E or H2-1E/F receiver modes and low integration times ?t of 10 or 20 ms should be chosen. Since the lightning flash rate might be low (<1 flash per hour) it is important to have long observation times. An analysis of all Cassini trajectories of Titan close flybys shows that the spacecraft would have the opportunity to observe Titan's dayside within 100 Titan radii during nearly all flybys. This time should be long enough, even if the lightning flash rate is low.

Nucleotide Docking: Prediction of Reactant State Complexes for Ribonuclease Enzymes  

SciTech Connect (OSTI)

Ribonuclease enzymes (RNases) play key roles in the maturation and metabolism of all RNA molecules. Computational simulations of the processes involved can help to elucidate the underlying enzymatic mechanism and is often employed in a synergistic approach together with biochemical experiments. Theoretical calculations require atomistic details regarding the starting geometries of the molecules involved, which, in the absence of crystallographic data, can only be achieved from computational docking studies. Fortunately, docking algorithms have improved tremendously in recent years, so that reliable structures of enzyme-ligand complexes can now be successfully obtained from computation. However, most docking programs are not particularly optimized for nucleotide docking. In order to assist our studies on the cleavage of RNA by the two most important ribonuclease enzymes, RNase A and RNase H, we evaluated four docking tools - MOE2009, Glide 5.5, QXP-Flo+0802, and Autodock 4.0 - for their ability to simulate complexes between these enzymes and RNA oligomers. To validate our results, we analyzed the docking results with respect to the known key interactions between the protein and the nucleotide. In addition, we compared the predicted complexes with X-ray structures of the mutated enzyme as well as with structures obtained from previous calculations. In this manner, we were able to prepare the desired reaction state complex so that it could be used as the starting structure for further DFT/B3LYP QM/MM reaction mechanism studies.

ARCADE small-scale docking mechanism for micro-satellites  

Science Journals Connector (OSTI)

The development of on-orbit autonomous rendezvous and docking (ARD) capabilities represents a key point for a number of appealing mission scenarios that include activities of on-orbit servicing, automated assembly of modular structures and active debris removal. As of today, especially in the field of micro-satellites ARD, many fundamental technologies are still missing or require further developments and micro-gravity testing. In this framework, the University of Padova, Centre of Studies and Activities for Space (CISAS), developed the Autonomous Rendezvous Control and Docking Experiment (ARCADE), a technology demonstrator intended to fly aboard a BEXUS stratospheric balloon. The goal was to design, build and test, in critical environment conditions, a proximity relative navigation system, a custom-made reaction wheel and a small-size docking mechanism. The ARCADE docking mechanism was designed against a comprehensive set of requirements and it can be classified as small-scale, central, gender mating and unpressurized. The large use of commercial components makes it low-cost and simple to be manufactured. Last, it features a good tolerance to off-nominal docking conditions and a by-design soft docking capability. The final design was extensively verified to be compliant with its requirements by means of numerical simulations and physical testing. In detail, the dynamic behaviour of the mechanism in both nominal and off-nominal conditions was assessed with the multibody dynamics analysis software MD ADAMS 2010 and functional tests were carried out within the fully integrated ARCADE experiment to ensure the docking system efficacy and to highlight possible issues. The most relevant results of the study will be presented and discussed in conclusion to this paper.

Lightning and radar observations of hurricane Rita landfall  

SciTech Connect (OSTI)

Los Alamos National Laboratory (LANL) owns and operates an array of Very-Low Frequency (VLF) sensors that measure the Radio-Frequency (RF) waveforms emitted by Cloud-to-Ground (CG) and InCloud (IC) lightning. This array, the Los Alamos Sferic Array (LASA), has approximately 15 sensors concentrated in the Great Plains and Florida, which detect electric field changes in a bandwidth from 200 Hz to 500 kHz (Smith et al., 2002). Recently, LANL has begun development of a new dual-band RF sensor array that includes the Very-High Frequency (VHF) band as well as the VLF. Whereas VLF lightning emissions can be used to deduce physical parameters such as lightning type and peak current, VHF emissions can be used to perform precise 3d mapping of individual radiation sources, which can number in the thousands for a typical CG flash. These new dual-band sensors will be used to monitor lightning activity in hurricanes in an effort to better predict intensification cycles. Although the new LANL dual-band array is not yet operational, we have begun initial work utilizing both VLF and VHF lightning data to monitor hurricane evolution. In this paper, we present the temporal evolution of Rita's landfall using VLF and VHF lightning data, and also WSR-88D radar. At landfall, Rita's northern eyewall experienced strong updrafts and significant lightning activity that appear to mark a transition between oceanic hurricane dynamics and continental thunderstorm dynamics. In section 2, we give a brief overview of Hurricane Rita, including its development as a hurricane and its lightning history. In the following section, we present WSR-88D data of Rita's landfall, including reflectivity images and temporal variation. In section 4, we present both VHF and VLF lightning data, overplotted on radar reflectivity images. Finally, we discuss our observations, including a comparison to previous studies and a brief conclusion.

X-ray Emission from Thunderstorms and Lightning  

ScienceCinema (OSTI)

How lightning is initiated in the relatively low electric fields inside thunderclouds and how it can then propagate for tens of kilometers through virgin air are two of the great unsolved problems in the atmospheric sciences. Until very recently it was believed that lightning was entirely a conventional discharge, involving only low-energy (a few eV) electrons. This picture changed completely a few years ago with the discovery of intense x-ray emission from both natural cloud-to-ground lightning and rocket-triggered lightning. This energetic emission cannot be produced by a conventional discharge, and so the presence of x-rays strongly implies that runaway breakdown plays a role in lightning processes. During runaway breakdown, electrons are accelerated through air to nearly the speed of light by strong electric fields. These runaway electrons then emit bremsstrahlung x-rays and gamma-rays during collisions with air. Indeed, the x-ray and gamma-ray emission produced by runaway breakdown near the tops of thunderstorms is bright enough to be seen from outer space, 600 km away. As a result, the physics used for decades to describe thunderstorm electrification and lightning discharges is incomplete and needs to be revisited.

SciTech Connect (OSTI)

An assessment of the 32 year historical reliability of the 13.8 kV electrical distribution system at the Oak Ridge National Laboratory (ORNL) in Tennessee has yielded several conclusions useful In the planning of Industrial power Systems. The system configuration at ORNL has essentially remained unchanged in the last 32 years which allows a meaningful comparison of reliability trends for the plant`s eight overhead distribution lines, two of which were built in the 1960`s with lightning resistant construction techniques. Meticulous records indicating the cause, duration, and location of 135 electric outages in the plant`s distribution system have allowed a reliability assessment to be performed. The assessment clearly shows how differences in voltage construction class, length, age, and maximum elevation above a reference elevation influence the reliability of overhead power distribution lines. Comparisons are also made between the ORNL historical data and predicted failure rates from ANSI and IEEE industry surveys.

Waste Isolation Pilot Plant TruDock crane system analysis  

SciTech Connect (OSTI)

The WIPP TruDock crane system located in the Waste Handling Building was identified in the WIPP Safety Analysis Report (SAR), November 1995, as a potential accident concern due to failures which could result in a dropped load. The objective of this analysis is to evaluate the frequency of failure of the TruDock crane system resulting in a dropped load and subsequent loss of primary containment, i.e. drum failure. The frequency of dropped loads was estimated to be 9.81E-03/year or approximately one every 102 years (or, for the 25% contingency, 7.36E-03/year or approximately one every 136 years). The dominant accident contributor was the failure of the cable/hook assemblies, based on failure data obtained from NUREG-0612, as analyzed by PLG, Inc. The WIPP crane system undergoes a rigorous test and maintenance program, crane operation is discontinued following any abnormality, and the crane operator and load spotter are required to be trained in safe crane operation, therefore it is felt that the WIPP crane performance will exceed the data presented in NUREG-0612 and the estimated failure frequency is felt to be conservative.

After discretization by the method so-called FDTD (Finite Difference Time Domain) of the lines equations excited by a lightning wave and the application in every node of the network in current and voltage, we deduct a equations system, of which the resolution permits us to deduct the induced electric quantities in every node of the network. In order to confirm our theoretical work, we present a set of applications that allows validating this study.

Update Direct-Strike Lightning Environment for Stockpile-to-Target Sequence

The University of Florida has surveyed all relevant publications reporting lightning characteristics and presents here an up-to-date version of the direct-strike lightning environment specifications for nuclear weapons published in 1989 by R. J. Fisher and M. A. Uman. Further, we present functional expressions for current vs. time, current derivative vs. time, second current derivative vs. time, charge transfer vs. time, and action integral (specific energy) vs. time for first return strokes, for subsequent return strokes, and for continuing currents; and we give sets of constants for these expressions so that they yield approximately the median and extreme negative lightning parameters presented in this report. Expressions for the median negative lightning waveforms are plotted. Finally, we provide information on direct-strike lightning damage to metals such as stainless steel, which could be used as components of storage containers for nuclear waste materials; and we describe UF's new experimental research program to add to the sparse data base on the properties of positive lightning. Our literature survey, referred to above, is included in four Appendices. The following four sections (II, III, IV, and V) of this final report deal with related aspects of the research: Section II. Recommended Direct-Strike Median and Extreme Parameters; Section III. Time-Domain Waveforms for First Strokes, Subsequent Strokes, and Continuing Currents; Section IV. Damage to Metal Surfaces by Lightning Currents; and Section V. Measurement of the Characteristics of Positive Lightning. Results of the literature search used to derive the material in Section II and Section IV are found in the Appendices: Appendix 1. Return Stroke Current, Appendix 2. Continuing Current, Appendix 3. Positive Lightning, and Appendix 4. Lightning Damage to Metal Surfaces.

Arc Energy Estimations: Applications in Lightning-Induced Concrete Spall  

SciTech Connect (OSTI)

After lightning contacts a building, the possibility of a physical break in its conductive path to ground may exist. Given such a break, an electric field may develop across the gap until it exceeds the breakdown strength of the non-conducting, or dielectric, material. Breakdown subsequently occurs and energy is dissipated during the development of an arc channel. If the dielectric is concrete, a concern exists that the energy available for arc formation may be capable of launching pieces of spall into sensitive equipment. This paper discusses the mechanisms of energy dissipation in arc formation and quantifies the energy available for concrete spall.

Assessment and analysis of indirect lightning performance of overhead lines  

Science Journals Connector (OSTI)

Abstract This paper presents an efficient method for the assessment of the indirect lightning performance of overhead power lines and analyses the influence of some relevant parameters on the flashover rate. The method is based on a formula to calculate the peak value of lightning-induced voltages in overhead lines over a lossy ground, which considers the front-time of the channel-base current. The results of the method are validated by comparison with results available in the literature. The method is then used to investigate the effect of subsequent strokes on the line flashover rate, leading to the conclusion that their contribution is negligible, as long as no correlation is assumed between front-time and peak value of the strokes (first and subsequent). In the following, the method is used to analyze the influence of some parameters on the lightning performance of overhead lines. The results show that the stroke current front-time influence decreases as the soil resistivity increases, and that a higher front-time leads to a lower flashover rate. It is shown that the use of a fixed front-time T=5.63?s for the first strokes leads to results that match well the results obtained from Cigrs front-time probabilistic distribution. Regarding the return stroke velocity, the results show that, for soils with resistivity higher than 100?m, the flashover rate increases as the return stroke velocity increases. The results also show that a relative velocity vr=0.4 leads to flashover rates that match well the results obtained considering some correlations between return stroke velocity and peak current proposed in the literature. The influence of the correlation between current peak value and front-time for first strokes is also analyzed and it is shown that the correlation reduces the flashover rate. It is also shown that considering this correlation for first strokes and not for subsequent strokes increases the contribution of the latter to the flashover rate, especially for good conducting soils.

Protection characteristics of a Faraday cage compromised by lightning burnthrough.  

SciTech Connect (OSTI)

A lightning flash consists of multiple, high-amplitude but short duration return strokes. Between the return strokes is a lower amplitude, continuing current which flows for longer duration. If the walls of a Faraday cage are made of thin enough metal, the continuing current can melt a hole through the metal in a process called burnthrough. A subsequent return stroke can couple energy through this newly-formed hole. This LDRD is a study of the protection provided by a Faraday cage when it has been compromised by burnthrough. We initially repeated some previous experiments and expanded on them in terms of scope and diagnostics to form a knowledge baseline of the coupling phenomena. We then used a combination of experiment, analysis and numerical modeling to study four coupling mechanisms: indirect electric field coupling, indirect magnetic field coupling, conduction through plasma and breakdown through the hole. We discovered voltages higher than those encountered in the previous set of experiments (on the order of several hundreds of volts).

A simple approach to improve lightning performance of an uprated substation  

SciTech Connect (OSTI)

This paper presents a simple method to minimize lightning surges entering an uprated or compact substation. A severe lightning stress is caused by a backflashover in close proximity to the substation. Feasibility of uprating is based on the surge arrester technology available at present. However, some aspects of line design offer opportunities in reducing frequency and severity of lightning surges imposed on the substation. The tower surge response adds an inductive overshoot only during the front of the stroke which reduces considerably during the tail. If backflashover does not occur before reflections from adjacent towers arrive, it is unlikely to occur at all. Use of guys and underbuilt ground wires in the limiting distance will produce reflections with larger magnitude and reduce the effective surge impedance of the tower. This would not only reduce backflashover frequency but will also minimize crest and duration of surges entering the substation.

On presentation of lightning flash in thundercloud as collective spontaneous radiation (superradiation) pulse  

E-Print Network [OSTI]

In this paper we conjecture that some specific properties of an electroactive region of thunderclouds play the major role in an initiation of a lightning flash. The electroactive region is modeled here as a quantum two-level system of oxygen molecules which are assumed to have two (ground and excited) states, where transitions from ground to excited states come as a result of micro-discharges between ice particles. In this case lightning flash corresponds to the pulse of collective spontaneous radiation caused by the deexcitations of excited oxygen molecules from metastable state into ground state.

During the summer of 1991, nine negative cloud-to-ground lightning flashes, comprising a total of 38 individual return strokes, were triggered to designated attachment points on a munitions storage bunker. Measurements were simultaneously made of the incident flash currents, both return-stroke and continuing current components, and of response at 24 test points located throughout the bunker. The recorded responses included currents, voltages, and electric and magnetic fields throughout the structure and its lightning protection system. The maximum responses observed at each test point, as directly measured and a linearly scaled to median and severe return-stroke incident current amplitudes, are presented and discussed. 8 refs.

Comparing Evolutionary Programs and Evolutionary Pattern Search Algorithms: A Drug Docking Application  

SciTech Connect (OSTI)

Evolutionary programs (EPs) and evolutionary pattern search algorithms (EPSAS) are two general classes of evolutionary methods for optimizing on continuous domains. The relative performance of these methods has been evaluated on standard global optimization test functions, and these results suggest that EPSAs more robustly converge to near-optimal solutions than EPs. In this paper we evaluate the relative performance of EPSAs and EPs on a real-world application: flexible ligand binding in the Autodock docking software. We compare the performance of these methods on a suite of docking test problems. Our results confirm that EPSAs and EPs have comparable performance, and they suggest that EPSAs may be more robust on larger, more complex problems.

Lightning arrestor connector lead magnesium niobate qualification pellet test procedures.  

SciTech Connect (OSTI)

Enhanced knowledge preservation for DOE DP technical component activities has recently received much attention. As part of this recent knowledge preservation effort, improved documentation of the sample preparation and electrical testing procedures for lead magnesium niobate--lead titanate (PMN/PT) qualification pellets was completed. The qualification pellets are fabricated from the same parent powders used to produce PMN/PT lightning arrestor connector (LAC) granules at HWF&T. In our report, the procedures for fired pellet surface preparation, electrode deposition, electrical testing and data recording are described. The dielectric measurements described in our report are an information only test. Technical reasons for selecting the electrode material, electrode size and geometry are presented. The electrical testing is based on measuring the dielectric constant and dissipation factor of the pellet during cooling from 280 C to 220 C. The most important data are the temperature for which the peak dielectric constant occurs (Curie Point temperature) and the peak dielectric constant magnitude. We determined that the peak dielectric constant for our procedure would be that measured at 1 kHz at the Curie Point. Both the peak dielectric constant and the Curie point parameters provide semi-quantitative information concerning the chemical and microstructural homogeneity of the parent material used for the production of PMN/PT granules for LACs. Finally, we have proposed flag limits for the dielectric data for the pellets. Specifically, if the temperature of the peak dielectric constant falls outside the range of 250 C {+-} 30 C we propose that a flag limit be imposed that will initiate communication between production agency and design agency personnel. If the peak dielectric constant measured falls outside the range 25,000 {+-} 10,000 we also propose that a flag limit be imposed.

One important part of the research efforts is the evaluation of operational limits (weather limits) of different vessel/access concepts for transportation of maintenance personnel, equipment, and spare parts to the offshore wind turbines. This paper gives a brief description of possible types of service vessel and access system. It presents methodologies for numerical analysis of docking operation by an active motion compensated access device and a simple fender. The proposed frequencydomain approach to the analysis of docking operation with fender is new and highly efficient compared to timedomain simulation. The methods have been applied to two vessel/access concepts in this paper and they can be used in docking operability assessments for a variety of vessels that employ an active motion compensated device or a fender as access system to offshore wind turbines.

Observation of cloud-to-ground lightning channels with high-speed video camera  

E-Print Network [OSTI]

Between May and October 2013 (period of sustained thunderstorm activity in France), several cloud-to-ground lightning flashes have been observed in Paris area with a high-speed video camera (14000 frames per second). The localization and the polarity of the recorded cloud-to-ground flashes have been obtained from the French lightning detection network M{\\'e}t{\\'e}orage which is equipped with the same low frequency sensors used by the US NLDN. In this paper we focused on 7 events (3 positive cloud-to-ground lightning flashes and 4 negative cloud-to-ground lightning flashes). The propagation velocity of the leaders and its temporal evolution have been estimated; the evolution of branching of the negative leaders have been observed during the propagation of the channel which get connected to ground and initiate the first return stroke. One aim of this preliminary study is to emphasize the differences between the characteristics of the positive and of the negative leaders.

Automated docking of {alpha}-(1,4)- and {alpha}-(1,6)-linked glucosyl trisaccharides in the glucoamylase active site  

SciTech Connect (OSTI)

Low-energy conformers of five {alpha}-(1,4)- and {alpha}-(1,6)-linked glucosyl trisaccharides were flexibly docked into the glucoamylase active site using AutoDock 2.2. To ensure that all significant conformational space was searched, the starting trisaccharide conformers for docking were all possible combinations of the corresponding disaccharide low-energy conformers. All docked trisaccharides occupied subsites {minus}1 and +1 in very similar modes to those of corresponding nonreducing-end disaccharides. For linear substrates, full binding at subsite +2 occurred only when the substrate reducing end was {alpha}-(1,4)-linked, with hydrogen-bonding with the hydroxy-methyl group being the only polar interaction there. Given the absence of other important interactions at this subsite, multiple substrate conformations are allowed. For the one docked branched substrate, steric hindrance in the {alpha}-(1,6)-glycosidic oxygen suggests that the active-site residues have to change position for hydrolysis to occur. Subsite +1 of the glucoamylase active site allows flexibility in binding but, at least in Aspergillus glucoamylases, subsite +2 selectively binds substrates {alpha}-(1,4)-linked between subsites +1 and +2. Enzyme engineering to limit substrate flexibility at subsite +2 could improve glucoamylase industrial properties.

Health effects of electromagnetic field generated by lightning current pulses near down conductors  

Science Journals Connector (OSTI)

The lightning current generates a time varying magnetic field near down conductors, when lightning strikes the connected Franklin-rod. The down conductors are mounted on the wall of buildings, where residential places can be situated. It is well known that the rapidly changing magnetic fields could generate dangerous eddy currents in the human body. If the duration and the gradient of the magnetic field were high enough, the peripheral nerves are excited. In this study, the authors introduce an improved model of the interaction of electromagnetic fields of lighting current near a down conductor with the human body. The interaction model has two parts: estimation of the magnetic fields surrounding the down conductor and evaluation of health effects of rapid changing magnetic fields on the human body.

DNA Activity  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

DNA Activity DNA Activity Name: Sara Location: N/A Country: N/A Date: N/A Question: Is DNA an anion or a cation? I thought since it was negatively charged it was an anion but mt teacher in class today said it was a cation because negatively charged molecules logically migrate to the positively charged plate of the cathode, ie molecules that migrate towards a cathode are cations. Where is the error in my logic or there error in my logic? Replies: DNA is negatively charged due to the phosphate ions present in the ribose-phosphate backbone. It moves towards the positive pole during electrophoresis. The definition kation/anion is confusing because: 1. a cation moves to the cathode 2. the cathode is negative, thus 3. a cation is positive DNA is an anion. The confusion is that a cathode is negative, but a cation is positively charged. For that reason these terms are not generally used in this context.

A Ball Lightning Model as a Possible Explanation of Recently Reported Cavity Lights  

SciTech Connect (OSTI)

The salient features of cavity lights, in particular, mobile luminous objects (MLO's), as have been experimentally observed in superconducting accelerator cavities, are summarized. A model based upon standard electromagnetic interactions between a small particle and the 1.5 GHz cavity excitation field is described. This model can explain some features of these data, in particular, the existence of particle orbits without wall contact. While this result is an important success for the model, it is detailed why the model as it stands is incomplete. It is argued that no avenues for a suitable extension of the model through established physics appear evident, which motivates an investigation of a model based upon a more exotic object, ball lightning. As discussed, further motivation derives from the fact that there are significant similarities in many of the qualitative features of ball lightning and MLO's, even though they appear in quite different circumstances and differ in scale by orders of magnitude. The ball lightning model, which incorporates electromagnetic charges and currents, is based on a symmetrized set of Maxwell's equations in which the electromagnetic sources and fields are characterized by a process called dyality rotation. It is shown that a consistent mathematical description of dyality rotation as a physical process can be achieved by adding suitable (phenomenological) current terms to supplement the usual current terms in the symmetrized Maxwell's equations. These currents, which enable the conservation of electric and magnetic charge, are called vacuum currents. It is shown that the proposed ball lightning model offers a good qualitative explanation of the perplexing aspects of the MLO data. Avenues for further study are indicated.

Physical mechanism and numerical simulation of the inception of the lightning upward leader  

SciTech Connect (OSTI)

The upward leader is a key physical process of the leader progression model of lightning shielding. The inception mechanism and criterion of the upward leader need further understanding and clarification. Based on leader discharge theory, this paper proposes the critical electric field intensity of the stable upward leader (CEFISUL) and characterizes it by the valve electric field intensity on the conductor surface, E{sub L}, which is the basis of a new inception criterion for the upward leader. Through numerical simulation under various physical conditions, we verified that E{sub L} is mainly related to the conductor radius, and data fitting yields the mathematical expression of E{sub L}. We further establish a computational model for lightning shielding performance of the transmission lines based on the proposed CEFISUL criterion, which reproduces the shielding failure rate of typical UHV transmission lines. The model-based calculation results agree well with the statistical data from on-site operations, which show the effectiveness and validity of the CEFISUL criterion.

Monte Carlo estimation of the rates of lightning strikes on power lines  

Science Journals Connector (OSTI)

This paper reports the development of a general method for estimating the rates of lightning strikes on transmission lines using Monte Carlo simulation. Effects of towers, cross-arms, non-level ground, conductor sags and nearby structures are directly represented in the 3-dimension electrogeometric model (EGM). The method developed is a general one that is applicable to any transmission line configuration and is independent of the EGM used. Tedious analytical derivation of more than 100 equations for each configuration as required by analytical methods is avoided altogether. The formulation and a flow chart are detailed in the paper. The shortest distances from the lightning leader tip to individual structures that may be struck are evaluated and then compared with striking distances. The outcome of the comparison identifies the structure which will be struck in each simulation. The exposure area adopted in the simulation is determined on the basis of the transmission line route length and the maximum possible striking distance to ensure that the simulation results in a maximum possible number of strikes on the overhead line. Strokes outside the exposure area will always miss the transmission line and, therefore, have no effects on the results. The method proposed and its software implementation are verified on the basis of results from analytical methods of earlier work, and from field data.

New Computational Approaches for NMR-based Drug Design: A Protocol for Ligand Docking to Flexible Target Sites  

SciTech Connect (OSTI)

NMR-based drug design has met with some success in the last decade, as illustrated in numerous instances by Fesik's ''ligand screening by NMR'' approach. Ongoing efforts to generalize this success have led us to the development of a new paradigm in which quantitative computational approaches are being integrated with NMR derived data and biological assays. The key component of this work is the inclusion of the intrinsic dynamic quality of NMR structures in theoretical models and its use in docking. A new computational protocol is introduced here, designed to dock small molecule ligands to flexible proteins derived from NMR structures. The algorithm makes use of a combination of simulated annealing monte carlo simulations (SA/MC) and a mean field potential informed by the NMR data. The new protocol is illustrated in the context of an ongoing project aimed at developing new selective inhibitors for the PCAF bromodomains that interact with HIV Tat.

AC and lightning performance of fiberglass crossarms aged in 115 kV transmission line  

SciTech Connect (OSTI)

This paper presents the results of an investigation of the electrical performance of 115 kV transmission line fiberglass cross-arm used by Mississippi Power and Light Company. A transmission line fiberglass crossarm removed from service and companion cross-arms outdoors but not in service were examined. The evaluation of electrical performance was based on flashover voltage value at AC voltage and standard lightning impulses as well as under dry and wet conditions. The tests were performed in the Mississippi State University High Voltage Laboratory. The obtained flashover voltages show no large differences in electrical strength of fiberglass crossarms removed from service and those stored outdoors. The Added CFO voltage by fiberglass crossarm to the porcelain suspension insulators is presented versus the length of the fiberglass crossarm for dry and wet conditions.

Controlling DNA Methylation  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Controlling DNA Methylation Though life on earth is composed of a diverse range of organisms, some with many different types of tissues and cells, all these are encoded by a molecule we call DNA. The information required to build a protein is stored in DNA within the cells. Not all the message in the DNA is used in each cell and not all the message is used all the time. During cell differentiation, the cells become dedicated for their specific function which involves selectively activating some genes and repressing others. Gene regulation is an important event in the developmental biology and the biology of various diseases, but a more complex process.

During cell differentiation, the cells become dedicated for their specific function which involves selectively activating some genes and repressing others. Gene regulation is an important event in the developmental biology and the biology of various diseases, but a more complex process. In the bacteria there are distinct enzymes while one is capable of cleaving DNA, the other protects DNA by modification. The complementary function provided by the set of enzymes offers a defense mechanism against the phage infection and DNA invasion. The incoming DNA is cleaved sequence specifically by the class of enzymes called restriction endonuclease (REase). The host DNA is protected by the sequence specific action of matching set of enzymes called the DNA methyltransferase (MTase). The control of the relative activities of the REase and MTase is critical because a reduced ratio of MTase/REase activity would lead to cell death via autorestriction. However too high a ratio would fail to provide protection against invading viral DNA. In addition a separate group of proteins capable of controlling R-M proteins have been identified in various restriction-modification (R-M) systems which are called C proteins (Roberts et al., 2003).

DNA's Role with Proteins  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

DNA's Role with Proteins DNA's Role with Proteins Name: Hans Location: N/A Country: N/A Date: N/A Question: Is it sure that the most important information of living cells is stored in the DNA? DNA seems to be nothing more than an inventory of useful proteins and a tool to create those proteins. Could it be that more important operational know how of how these proteins interact to build a living organism is actually located in the rest of the cell? So that the rest of the cell is the most important inheritance, whereas DNA merely takes care of the genetic variation? Replies: DNA is the entire library of protein information for an organism. All seven types of protein. It is true that in developmental stages of an organism that the presence and absences of certain proteins and other chemicals generated by proteins will influence what the DNA in a "particular" cell will express. Hence, you can start out with one cell and end up with a complex organism. You may have heard some of this information with the cloning activities that have been going on lately. All the inheritance comes from the DNA, but what parts of the DNA expression may be dictated by the cells special characteristics developed upon specializing. In that way the liver cells will only do "liver" things and the kidney cells will only do "kidney" things, BUT they use the same DNA information to operate, just a different portion of the same DNA that pertains to their particular "job". If you can convince a cell that it does not have a special job anymore, then you can develop the entire organism from this cell with the right signals; this is what cloning techniques have done!

Modeling Techniques Used to Analyze Safety of Payloads for Generic Missile Type Weapons Systems During an Indirect Lightning Strike  

SciTech Connect (OSTI)

During lightning strikes buildings and other structures can act as imperfect Faraday Cages, enabling electromagnetic fields to be developed inside the facilities. Some equipment stored inside these facilities may unfortunately act as antenna systems. It is important to have techniques developed to analyze how much voltage, current, or energy dissipation may be developed over valuable components. In this discussion we will demonstrate the modeling techniques used to accurately analyze a generic missile type weapons system as it goes through different stages of assembly. As work is performed on weapons systems detonator cables can become exposed. These cables will form different monopole and loop type antenna systems that must be analyzed to determine the voltages developed over the detonator regions. Due to the low frequencies of lightning pulses, a lumped element circuit model can be developed to help analyze the different antenna configurations. We will show an example of how numerical modeling can be used to develop the lumped element circuit models used to calculate voltage, current, or energy dissipated over the detonator region of a generic missile type weapons system.

Estimation of the minimum shielding failure flashover current for first and subsequent lightning strokes to overhead transmission lines  

Science Journals Connector (OSTI)

Abstract ATP-EMTP simulations are performed to estimate the minimum shielding failure current causing flashover in overhead transmission lines with operating voltage in the range of 66kV up to 735kV. This critical current, affecting shielding failure flashover rate, is of great importance for assessing the insulation coordination of overhead transmission lines and the connected substations. The minimum shielding failure current causing flashover of line insulation is highly dependent upon insulator string flashover modelling and, also, markedly higher than that calculated according to the relevant IEEE Std 1243-1997 simplified expression. A modification of the latter is suggested by using multiplication factors of 1.5 and 1.65 for first and subsequent lightning strokes, respectively, so as to account for the increased dielectric strength of line insulator strings under non-standard lightning overvoltage surges. Alternatively, the critical currents can be respectively estimated by using average negative breakdown gradients per unit length of insulator string of 680kV/m and 750kV/m. The shielding failure flashover rate of the overhead transmission lines, being greatly influenced by insulator string flashover modelling, is lower than that obtained based on the critical current according to IEEE Std 1243-1997.

Close electric fields and lightning-induced voltages predicted by a return-stroke model including corona and nonlinear channel resistance  

Science Journals Connector (OSTI)

Abstract In this paper, a return-stroke model based on nonuniform transmission line theory that includes nonlinear losses and corona is used for calculating close electric fields and lightning-induced voltages on an overhead line. A study is performed to identify the influence of return-stroke corona on close electric fields and line overvoltages considering different model assumptions. It is shown that the consideration of corona affects the attenuation and distortion of the return-stroke current. Close vertical electric fields predicted by the model present waveforms, peak values, and decay with distance that are in agreement with measured data. A simpler case in which the return-stroke speed is artificially set to a prescribed value by controlling the inductance and capacitance of the channel is shown to lead to results that are in agreement with the complete return-stroke model considering nonlinear losses and corona. Similar conclusions apply to popular engineering return-stroke models typically used in lightning-induced voltage calculations provided the return-stroke speed is suitably adjusted. It is also shown that lightning-induced voltages calculated with the considered model are in good agreement with experimental data.

Chiral Mesophases of DNA  

E-Print Network [OSTI]

In the hexagonal columnar phase of chiral polymers a bias towards cholesteric twist competes with braiding along an average direction. When the chirality is strong, topological defects proliferate, leading to either a tilt grain boundary phase or a new ``moire state'' with twisted bond order. This moire phase can melt leading to a new phase: the chiral hexatic. I will discuss some recent experimental results from the NIH on DNA liquid crystals in the context of these theories.

Annual Report: 2010-2011 Storm Season Sampling For NON-DRY DOCK STORMWATER MONITORING FOR PUGET SOUND NAVAL SHIPYARD, BREMERTON, WA  

SciTech Connect (OSTI)

This interim report summarizes the stormwater monitoring conducted for non-dry dock outfalls in both the confined industrial area and the residential areas of Naval Base Kitsap within the Puget Sound Naval Shipyard (referred to as the Shipyard). This includes the collection, analyses, and descriptive statistics for stormwater sampling conducted from November 2010 through April 2011. Seven stormwater basins within the Shipyard were sampled during at least three storm events to characterize non-dry dock stormwater discharges at selected stormwater drains located within the facility. This serves as the Phase I component of the project and Phase II is planned for the 2011-2012 storm season. These data will assist the Navy, USEPA, Ecology and other stakeholders in understanding the nature and condition of stormwater discharges from the Shipyard and inform the permitting process for new outfall discharges. The data from Phase I was compiled with current stormwater data available from the Shipyard, Sinclair/Dyes Inlet watershed, and Puget Sound in order to support technical investigations for the Draft NPDES permit. The permit would require storm event sampling at selected stormwater drains located within the Shipyard. However, the data must be considered on multiple scales to truly understand potential impairments to beneficial uses within Sinclair and Dyes Inlets.

Radiation and viral DNA Radiation and viral DNA Name: Loretta L Lamb Age: N/A Location: N/A Country: N/A Date: N/A Question: Can viral DNA be changed through exposure to radiation? If so, what type of radiation will do this? Can these irradiated viruses cause changes in the genome of any human cells they may infect? Can these (or any) viruses actually cause cancer, or do they merely act as triggering devices for cancer? Replies: In theory, any nucleic acid (viral or otherwise) can be changed by exposure to many kinds of radiation. Depending on the type of virus, these may then change the human cells that they infect. Although there are many different things that are being implicated in causing cancers, it looks like a fairly common model involves the sequential "knockout" of several human genes. Viruses may be one cause of such gene changes, radiation and other environmental causes may also contribute. Some of these changes may be inherited through families, so it becomes more likely that the environmental factors may happen to "hit" the right places in cells to cause cancers in these families. If you ask something more specific, perhaps I can focus my response a bit more

DNA attachment to support structures  

SciTech Connect (OSTI)

Microscopic beads or other structures are attached to nucleic acids (DNA) using a terminal transferase. The transferase adds labeled dideoxy nucleotide bases to the ends of linear strands of DNA. The labels, such as the antigens digoxigenin and biotin, bind to the antibody compounds or other appropriate complementary ligands, which are bound to the microscopic beads or other support structures. The method does not require the synthesis of a synthetic oligonucleotide probe. The method can be used to tag or label DNA even when the DNA has an unknown sequence, has blunt ends, or is a very large fragment (e.g., >500 kilobase pairs).

SciTech Connect (OSTI)

The various processes of DNA uptake by cells can be categorized as: viral DNA entry, conjugation, or transformation. Within each category, a variety of mechanisms have been found. However, considerable similarities occur among the different mechanisms of conjugation and, especially, transformation. All of these natural mechanisms of DNA transfer are quite elaborate and involve multiple protein components, as the case may be, of the virus, the donor cell, and the recipient cell. The mechanisms of viral infection and conjugation will be discussed mainly with respect to their relevance to transformation.

Genome-Wide Identification and 3D Modeling of Proteins involved in DNA Damage Recognition and Repair (Final Report)  

SciTech Connect (OSTI)

DNA Damage Recognition and Repair (DDR&R) proteins play a critical role in cellular responses to low-dose radiation and are associated with cancer. We have performed a systematic, genome-wide computational analysis of genomic data for human genes involved in the DDR&R process. The significant achievements of this project include: 1) Construction of the computational pipeline for searching DDR&R genes, building and validation of 3D models of proteins involved in DDR&R; 2) Functional and structural annotation of the 3D models and generation of comprehensive lists of suggested knock-out mutations; and the development of a method to predict the effects of mutations. Large scale testing of technology to identify novel small binding pockets in protein structures leading to new DDRR inhibitor strategies 3) Improvements of macromolecular docking technology (see the CAPRI 1-3 and 4-5 results) 4) Development of a new algorithm for improved analysis of high-density oligonucleotide arrays for gene expression profiling; 5) Construction and maintenance of the DNA Damage Recognition and Repair Database; 6) Producing 15 research papers (12 published and 3 in preparation).

Radiation-induced electron migration along DNA  

SciTech Connect (OSTI)

Radiation-induced electron migration along DNA is a mechanism by which randomly produced stochastic energy deposition events can lead to nonrandom types of damage along DNA manifested distal to the sites of the initial energy deposition. Electron migration along DNA is significantly influenced by the DNA base sequence and DNA conformation. Migration along 7 base pairs in oligonucleotides containing guanine bases was observed for oligonucleotides irradiated in solution which compares to average migration distances of 6 to 10 bases for Escherichia coli DNA irradiated in solution and 5.5 base pairs for Escherichia coli DNA irradiated in cells. Evidence also suggests that electron migration can occur preferentially in the 5{prime} to 3{prime} direction along DNA. Our continued efforts will provide information regarding the contribution of electron transfer along DNA to formation of locally multiply damaged sites created in DNA by exposure to ionizing radiation.

Chromosome specific repetitive DNA sequences  

DOE Patents [OSTI]

A method is provided for determining specific nucleotide sequences useful in forming a probe which can identify specific chromosomes, preferably through in situ hybridization within the cell itself. In one embodiment, chromosome preferential nucleotide sequences are first determined from a library of recombinant DNA clones having families of repetitive sequences. Library clones are identified with a low homology with a sequence of repetitive DNA families to which the first clones respectively belong and variant sequences are then identified by selecting clones having a pattern of hybridization with genomic DNA dissimilar to the hybridization pattern shown by the respective families. In another embodiment, variant sequences are selected from a sequence of a known repetitive DNA family. The selected variant sequence is classified as chromosome specific, chromosome preferential, or chromosome nonspecific. Sequences which are classified as chromosome preferential are further sequenced and regions are identified having a low homology with other regions of the chromosome preferential sequence or with known sequences of other family me This invention is the result of a contract with the Department of Energy (Contract No. W-7405-ENG-36).

DNA adsorption on synthetic and natural allophanes  

Science Journals Connector (OSTI)

The adsorption of DNA on natural and synthetic samples of allophane, which is a primary clay mineral of andosols, was investigated with respect to the DNA concentration, pH, ionic strength in the sample solution, and competition between DNA molecules and phosphate ions for adsorption to understand the behavior of extracellular DNA molecules in andosols. The relationships between DNA adsorption and the final concentrations were significantly fitted to a simple linear Langmuir equation. DNA adsorption decreased considerably with increasing suspension pH in the range between 3 and 9. The adsorption was less affected by the ionic strength of the suspension from 0.1 to 0.5molL?1. Under the same experimental conditions, DNA adsorption on allophanes was relatively higher than that on montmorillonite and silica but relatively lower than that on gibbsite and goethite. DNA adsorption on allophanes decreased on the addition of phosphate, indicating that there was a competition between DNA molecules and phosphate ions for adsorption on the minerals. These results suggested that DNA adsorption on allophanes occurred via two mechanisms: direct bonding of the phosphate group at the end of the DNA molecule to the OH groups of the Al-oxide layer on allophane, and the association of DNA molecules with the surface of negatively charged allophane via a bridging of inorganic cations.

Microfluidic DNA sample preparation method and device  

DOE Patents [OSTI]

Manipulation of DNA molecules in solution has become an essential aspect of genetic analyses used for biomedical assays, the identification of hazardous bacterial agents, and in decoding the human genome. Currently, most of the steps involved in preparing a DNA sample for analysis are performed manually and are time, labor, and equipment intensive. These steps include extraction of the DNA from spores or cells, separation of the DNA from other particles and molecules in the solution (e.g. dust, smoke, cell/spore debris, and proteins), and separation of the DNA itself into strands of specific lengths. Dielectrophoresis (DEP), a phenomenon whereby polarizable particles move in response to a gradient in electric field, can be used to manipulate and separate DNA in an automated fashion, considerably reducing the time and expense involved in DNA analyses, as well as allowing for the miniaturization of DNA analysis instruments. These applications include direct transport of DNA, trapping of DNA to allow for its separation from other particles or molecules in the solution, and the separation of DNA into strands of varying lengths.

Electromagnetic Signals from Bacterial DNA  

E-Print Network [OSTI]

Chemical reactions can be induced at a distance due to the propagation of electromagnetic signals during intermediate chemical stages. Although is is well known at optical frequencies, e.g. photosynthetic reactions, electromagnetic signals hold true for muck lower frequencies. In E. coli bacteria such electromagnetic signals can be generated by electric transitions between energy levels describing electrons moving around DNA loops. The electromagnetic signals between different bacteria within a community is a "wireless" version of intercellular communication found in bacterial communities connected by "nanowires". The wireless broadcasts can in principle be of both the AM and FM variety due to the magnetic flux periodicity in electron energy spectra in bacterial DNA orbital motions.

Single molecule studies of DNA mismatch repair  

Science Journals Connector (OSTI)

Abstract DNA mismatch repair, which involves is a widely conserved set of proteins, is essential to limit genetic drift in all organisms. The same system of proteins plays key roles in many cancer related cellular transactions in humans. Although the basic process has been reconstituted in vitro using purified components, many fundamental aspects of DNA mismatch repair remain hidden due in part to the complexity and transient nature of the interactions between the mismatch repair proteins and DNA substrates. Single molecule methods offer the capability to uncover these transient but complex interactions and allow novel insights into mechanisms that underlie DNA mismatch repair. In this review, we discuss applications of single molecule methodology including electron microscopy, atomic force microscopy, particle tracking, FRET, and optical trapping to studies of DNA mismatch repair. These studies have led to formulation of mechanistic models of how proteins identify single base mismatches in the vast background of matched DNA and signal for their repair.

It is already known that such replication is controlled by a protein known as DnaA, a member of the AAA+ superfamily of ATPases. What has now been discovered is that the core of the initiator is not the closed-ring structure expected for this system. Instead, DnaA forms an open right-handed helix. In addition, the architecture indicates that this AAA+ superhelix will wrap coils of the DNA around its exterior, causing the DNA double helix to deform as a first step in the separation and unwinding of its strands. Eukaryotic and archaeal initiators also have the structural elements that promote open-helix formation, indicating that a spiral, open-ring AAA+ assembly is a conserved element from a common evolutionary ancestor of Archaea, Bacteria, and Eukarya.

Allosteric Modulation of DNA by Small Molecules  

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

Allosteric Modulation of DNA by Small Allosteric Modulation of DNA by Small Molecules Signals originating at the cell surface are conveyed by a complex system of interconnected signaling pathways to the nucleus. They converge at transcription factors, which in turn regulate the transcription of sets of genes that result in the gene expression. Many human diseases are caused by dysregulated gene expression and the oversupply of transcription factors may be required for the growth and metastatic behavior of human cancers. Cell permeable small molecules that can be programmed to disrupt transcription factor-DNA interfaces could silence aberrant gene expression pathways. Pyrrole-imidazole polyamides are DNA minor groove binding small molecules that are programmable for a large repertoire of DNA motifs.

DNA nanotechnology: understanding and optimisation through simulation  

E-Print Network [OSTI]

DNA nanotechnology promises to provide controllable self-assembly on the nanoscale, allowing for the design of static structures, dynamic machines and computational architectures. In this article I review the state-of-the art of DNA nanotechnology, highlighting the need for a more detailed understanding of the key processes, both in terms of theoretical modelling and experimental characterisation. I then consider coarse-grained models of DNA, mesoscale descriptions that have the potential to provide great insight into the operation of DNA nanotechnology if they are well designed. In particular, I discuss a number of nanotechnological systems that have been studied with oxDNA, a recently developed coarse-grained model, highlighting the subtle interplay of kinetic, thermodynamic and mechanical factors that can determine behaviour. Finally, new results highlighting the importance of mechanical tension in the operation of a two-footed walker are presented, demonstrating that recovery from an unintended `overstepp...

Crystal Structure of the Chromodomain Helicase DNA-binding Protein 1 (Chd1) DNA-binding Domain in Complex with DNA  

SciTech Connect (OSTI)

Chromatin remodelers are ATP-dependent machines that dynamically alter the chromatin packaging of eukaryotic genomes by assembling, sliding, and displacing nucleosomes. The Chd1 chromatin remodeler possesses a C-terminal DNA-binding domain that is required for efficient nucleosome sliding and believed to be essential for sensing the length of DNA flanking the nucleosome core. The structure of the Chd1 DNA-binding domain was recently shown to consist of a SANT and SLIDE domain, analogous to the DNA-binding domain of the ISWI family, yet the details of how Chd1 recognized DNA were not known. Here we present the crystal structure of the Saccharomyces cerevisiae Chd1 DNA-binding domain in complex with a DNA duplex. The bound DNA duplex is straight, consistent with the preference exhibited by the Chd1 DNA-binding domain for extranucleosomal DNA. Comparison of this structure with the recently solved ISW1a DNA-binding domain bound to DNA reveals that DNA lays across each protein at a distinct angle, yet contacts similar surfaces on the SANT and SLIDE domains. In contrast to the minor groove binding seen for Isw1 and predicted for Chd1, the SLIDE domain of the Chd1 DNA-binding domain contacts the DNA major groove. The majority of direct contacts with the phosphate backbone occur only on one DNA strand, suggesting that Chd1 may not strongly discriminate between major and minor grooves.

DNA hydration studied by neutron fiber diffraction  

SciTech Connect (OSTI)

The development of neutron high angle fiber diffraction to investigate the location of water around the deoxyribonucleic acid (DNA) double-helix is described. The power of the technique is illustrated by its application to the D and A conformations of DNA using the single crystal diffractometer, D19, at the Institute Laue-Langevin, Grenoble and the time of flight diffractometer, SXD, at the Rutherford Appleton ISIS Spallation Neutron Source. These studies show the existence of bound water closely associated with the DNA. The patterns of hydration in these two DNA conformations are quite distinct and are compared to those observed in X-ray single crystal studies of two-stranded oligodeoxynucleotides. Information on the location of water around the DNA double-helix from the neutron fiber diffraction studies is combined with that on the location of alkali metal cations from complementary X-ray high angle fiber diffraction studies at the Daresbury Laboratory SRS using synchrotron radiation. These analyses emphasize the importance of viewing DNA, water and ions as a single system with specific interactions between the three components and provide a basis for understanding the effect of changes in the concentration of water and ions in inducing conformations] transitions in the DNA double-helix.

DNA DAMAGE QUANTITATION BY ALKALINE GEL ELECTROPHORESIS.  

SciTech Connect (OSTI)

Physical and chemical agents in the environment, those used in clinical applications, or encountered during recreational exposures to sunlight, induce damages in DNA. Understanding the biological impact of these agents requires quantitation of the levels of such damages in laboratory test systems as well as in field or clinical samples. Alkaline gel electrophoresis provides a sensitive (down to {approx} a few lesions/5Mb), rapid method of direct quantitation of a wide variety of DNA damages in nanogram quantities of non-radioactive DNAs from laboratory, field, or clinical specimens, including higher plants and animals. This method stems from velocity sedimentation studies of DNA populations, and from the simple methods of agarose gel electrophoresis. Our laboratories have developed quantitative agarose gel methods, analytical descriptions of DNA migration during electrophoresis on agarose gels (1-6), and electronic imaging for accurate determinations of DNA mass (7-9). Although all these components improve sensitivity and throughput of large numbers of samples (7,8,10), a simple version using only standard molecular biology equipment allows routine analysis of DNA damages at moderate frequencies. We present here a description of the methods, as well as a brief description of the underlying principles, required for a simplified approach to quantitation of DNA damages by alkaline gel electrophoresis.

Laser mass spectrometry for DNA sequencing, disease diagnosis, and fingerprinting  

SciTech Connect (OSTI)

Since laser mass spectrometry has the potential for achieving very fast DNA analysis, the authors recently applied it to DNA sequencing, DNA typing for fingerprinting, and DNA screening for disease diagnosis. Two different approaches for sequencing DNA have been successfully demonstrated. One is to sequence DNA with DNA ladders produced from Snager`s enzymatic method. The other is to do direct sequencing without DNA ladders. The need for quick DNA typing for identification purposes is critical for forensic application. The preliminary results indicate laser mass spectrometry can possibly be used for rapid DNA fingerprinting applications at a much lower cost than gel electrophoresis. Population screening for certain genetic disease can be a very efficient step to reducing medical costs through prevention. Since laser mass spectrometry can provide very fast DNA analysis, the authors applied laser mass spectrometry to disease diagnosis. Clinical samples with both base deletion and point mutation have been tested with complete success.

DNA fragment sizing and sorting by laser-induced fluorescence  

DOE Patents [OSTI]

A method is provided for sizing DNA fragments using high speed detection systems, such as flow cytometry to determine unique characteristics of DNA pieces from a sample. In one characterization the DNA piece is fragmented at preselected sites to produce a plurality of DNA fragments. The DNA piece or the resulting DNA fragments are treated with a dye effective to stain stoichiometrically the DNA piece or the DNA fragments. The fluorescence from the dye in the stained fragments is then examined to generate an output functionally related to the number of nucleotides in each one of the DNA fragments. In one embodiment, the intensity of the fluorescence emissions from each fragment is linearly related to the fragment length. The distribution of DNA fragment sizes forms a characterization of the DNA piece for use in forensic and research applications.

DNA-incorporating nanomaterials in biotechnological applications  

SciTech Connect (OSTI)

The recently developed ability to controllably connect biological and inorganic objects on a molecular scale opens a new page in biomimetic methods with potential applications in biodetection, tissue engineering, targeted therapeutics and drug/gene delivery. Particularly in the biodetection arena, a rapid development of new platforms has largely been stimulated by a spectrum of novel nanomaterials with physical properties that offer efficient, sensitive and inexpensive molecular sensing. Recently, DNA-functionalized nano-objects have emerged as a new class of nanomaterials that can be controllably assembled in predesigned structures. Such DNA-based nanoscale structures might provide a new detection paradigm due to their regulated optical, electrical and magnetic responses, chemical heterogeneity and high local biomolecular concentration. The specific biorecognition DNA and its physical-chemical characteristics allows for an exploitation of DNA-functionalized nanomaterials for sensing of nucleic acids, while a broad tunability of DNA interactions permits extending their use for detection of proteins, small molecules and ions. We discuss the progress that was achieved in the last decade in the exploration of new detection methods based on DNA-incorporating nanomaterials as well as their applications to gene delivery. The comparison between various detection platforms, their sensitivity and selectivity, and specific applications are reviewed.

Oligonucleotide and Long Polymeric DNA Encoding  

SciTech Connect (OSTI)

This report summarizes the work done at Lawrence Livermore National Laboratory for the Oligonucleotide and Long Polymeric DNA Encoding project, part of the Microelectronic Bioprocesses Program at DARPA. The goal of the project was to develop a process by which long (circa 10,000 base-pair) synthetic DNA molecules could be synthesized in a timely and economic manner. During construction of the long molecule, errors in DNA sequence occur during hybridization and/or the subsequent enzymatic process. The work done on this project has resulted in a novel synthesis scheme that we call the parallel pyramid synthesis protocol, the development of a suit of computational tools to minimize and quantify errors in the synthesized DNA sequence, and experimental proof of this technique. The modeling consists of three interrelated modules: the bioinformatics code which determines the specifics of parallel pyramid synthesis for a given chain of long DNA, the thermodynamics code which tracks the products of DNA hybridization and polymerase extension during the later steps in the process, and the kinetics model which examines the temporal and spatial processes during one thermocycle. Most importantly, we conducted the first successful syntheses of a gene using small starting oligomers (tetramers). The synthesized sequence, 813 base pairs long, contained a 725 base pair gene, modified green fluorescent protein (mGFP), which has been shown to be a functional gene by cloning into cells and observing its green fluorescent product.

When DNA Needs to Stand Up and Be Counted

When DNA Needs to Stand Up and Be Counted Print When DNA Needs to Stand Up and Be Counted Print DNA microarrays are small metal, glass, or silicon chips covered with patterns of short single-stranded DNA (ssDNA). These "DNA chips" are revolutionizing biotechnology, allowing scientists to identify and count many DNA sequences simultaneously. They are the enabling technology for genomic-based medicine and are a critical component of advanced diagnostic systems for medical and homeland security applications. Like digital chips, DNA chips are parallel, accurate, fast, and small. These advantages, however, can only be realized if the fragile biomolecules survive the attachment process intact. Furthermore, biomolecules must be properly oriented to perform their biological function. In other words, the DNA literally must stand up to be counted. Understanding both the attachment and orientation of DNA on gold surfaces was the goal of recent experiments performed at ALS Beamline 8.0.1 by an international collaboration of scientists.

Disorder in DNA-Linked Gold Nanoparticle Assemblies  

Science Journals Connector (OSTI)

We report experimental observations on the effect of disorder on the phase behavior of DNA-linked nanoparticle assemblies. Variation in DNA linker lengths results in different melting temperatures of the DNA-linked nanoparticle assemblies. We observed an unusual trend of a nonmonotonic zigzag pattern in the melting temperature as a function of DNA linker length. Linker DNA resulting in unequal DNA duplex lengths introduces disorder and lowers the melting temperature of the nanoparticle system. Comparison with free DNA thermodynamics shows that such an anomalous zigzag pattern does not exist for free DNA duplex melting, which suggests that the disorder introduced by unequal DNA duplex lengths results in this unusual collective behavior of DNA-linked nanoparticle assemblies.

Nucleotide sequence of Bacillus subtilis dnaB: a gene essential for DNA replication initiation and membrane attachment  

SciTech Connect (OSTI)

The complete nucleotide sequence of the Bacillus subtilis dnaB gene and its flanking regions was determined. The dnaB gene is essential for both replication initiation and membrane attachment of the origin region of the chromosome and plasmid pUB110. It has been known that there are two different classes (dnaBI and dnaBII) in the dnaB mutants; dnaBI is essential for both chromosome and pUB110 replication, whereas dnaBII is necessary only for chromosome replication. The nucleotide sequence revealed that dnaBI and dnaBII are two functional domains in the single dnaB gene. The mutation sites of two mutants, belonging to dnaBI and dnaBII, respectively, were also determined as substitutions of amino acids. The putative DnaB protein deduced from nucleotide sequence consists of 472 amino acids (55 kDa) with no cysteine residue. A 55-kDa polypeptide produced in an in vitro transcription-translation system was labeled with (/sup 35/S)methionine but not with (/sup 35/S)cysteine. The DnaB protein has a highly hydrophobic sequence of 20 amino acids in its N-terminal region, a possible DNA binding site, and two possible ATP binding sites. The dnaBI domain is between the DNA binding site and one of the ATP binding sites; the dnaBII domain is close to the other ATP binding site. Comparison of the amino acid sequence between the dnaB protein and those of other dna genes of Escherichia coli showed no homology, suggesting that the dnaB gene of B, subtilis may be analogous to a hitherto undiscovered gene in E. coli.

Electrospray ionization mass spectrometry (ESI-MS) has been used to study the noncovalent interaction of the 13.5-kDa DNA binding domain of PU.1 (PU.1-DBD) with specific double-stranded DNA (dsDNA) target molecules. Mixtures of PU.1-DBD protein and wildtype target DNA sequence yielded ESI-MS spectra showing only protein-dsDNA complex ions of 1:1 stoichiometry and free dsDNA. When PU.1-DBD protein, wild type target DNA, and a mutant target DNA lacking the consensus sequence were mixed, only the 1:1 complex with the wild-type DNA was observed, consistent with gel electrophoresis mobility shift assay results, demonstrating the observation of sequence-specific protein-dsDNA complexes using ESI-MS. 22 refs., 5 figs., 1 tab.

Optical selection and collection of DNA fragments. The present invention includes the optical selection and collection of large (>.mu.g) quantities of clonable, chromosome-specific DNA from a sample of chromosomes. Chromosome selection is based on selective, irreversible photoinactivation of unwanted chromosomal DNA. Although more general procedures may be envisioned, the invention is demonstrated by processing chromosomes in a conventional flow cytometry apparatus, but where no droplets are generated. All chromosomes in the sample are first stained with at least one fluorescent analytic dye and bonded to a photochemically active species which can render chromosomal DNA unclonable if activated. After passing through analyzing light beam(s), unwanted chromosomes are irradiated using light which is absorbed by the photochemically active species, thereby causing photoinactivation. As desired chromosomes pass this photoinactivation point, the inactivating light source is deflected by an optical modulator; hence, desired chromosomes are not photoinactivated and remain clonable. The selection and photoinactivation processes take place on a microsecond timescale. By eliminating droplet formation, chromosome selection rates 50 times greater than those possible with conventional chromosome sorters may be obtained. Thus, usable quantities of clonable DNA from any source thereof may be collected.

DNA nanotechnology: understanding and optimisation through simulation  

E-Print Network [OSTI]

DNA nanotechnology promises to provide controllable self-assembly on the nanoscale, allowing for the design of static structures, dynamic machines and computational architectures. In this article I review the state-of-the art of DNA nanotechnology, highlighting the need for a more detailed understanding of the key processes, both in terms of theoretical modelling and experimental characterisation. I then consider coarse-grained models of DNA, mesoscale descriptions that have the potential to provide great insight into the operation of DNA nanotechnology if they are well designed. In particular, I discuss a number of nanotechnological systems that have been studied with oxDNA, a recently developed coarse-grained model, highlighting the subtle interplay of kinetic, thermodynamic and mechanical factors that can determine behaviour. Finally, new results highlighting the importance of mechanical tension in the operation of a two-footed walker are presented, demonstrating that recovery from an unintended `overstepped' configuration can be accelerated by three to four orders of magnitude by application of a moderate tension to the walker's track. More generally, the walker illustrates the possibility of biasing strand-displacement processes to affect the overall rate.

Computationally Optimised DNA Assembly of synthetic genes  

Science Journals Connector (OSTI)

Gene synthesis is hampered by two obstacles: improper assembly of oligonucleotides; oligonucleotide defects incurred during chemical synthesis. To overcome the first problem, we describe the employment of a Computationally Optimised DNA Assembly (CODA) algorithm that uses the degeneracy of the genetic code to design overlapping oligonucleotides with thermodynamic properties for self-assembly into a single, linear, DNA product. To address the second problem, we describe a hierarchical assembly strategy that reduces the incorporation of defective oligonucleotides into full-length gene constructs. The CODA algorithm and these biological methods enable fast, simple and reliable assemblies of sequence-correct full-length genes.

DNA Duplication Revealed in New Beginnings DNA Duplication Revealed in New Beginnings DNA Duplication Revealed in New Beginnings April 3, 2012 - 9:36am Addthis The DNA replication origin recognition complex (ORC) is a six-protein machine with a slightly twisted half-ring structure (yellow). ORC is proposed to wrap around and bend approximately 70 base pairs of double stranded DNA (red and blue). When a replication initiator Cdc6 (green) joins ORC, the partial ring is now complete and ready to load another protein onto the DNA. This last protein (not shown) is the enzyme that unwinds the double stranded DNA so each strand can be replicated. | Illustration courtesy of Brookhaven Lab.

The process of compaction of high molecular weight DNA T4 is investigated directly in a AFM liquid cell. The AFM-images of globules formed by DNA molecules in the result of compaction in water-alcohol environments at high izopropanol concentration (80%) are received; it is found that at intermediate concentration of izopropanol (40-50%) the DNA molecules form partially compacted formations in which the separate coils of macromolecules twist in toroidal structures. It is shown using the technique of deconvolution of the AFM-images that the globule include only one closely packed DNA molecule. The model of DNA packing is proposed on the basis of AFM experiment.

When DNA Needs to Stand Up and When DNA Needs to Stand Up and Be Counted When DNA Needs to Stand Up and Be Counted Print Wednesday, 31 May 2006 00:00 DNA microarrays are small metal, glass, or silicon chips covered with patterns of short single-stranded DNA (ssDNA). These "DNA chips" are revolutionizing biotechnology, allowing scientists to identify and count many DNA sequences simultaneously. They are the enabling technology for genomic-based medicine and are a critical component of advanced diagnostic systems for medical and homeland security applications. Like digital chips, DNA chips are parallel, accurate, fast, and small. These advantages, however, can only be realized if the fragile biomolecules survive the attachment process intact. Furthermore, biomolecules must be properly oriented to perform their biological function. In other words, the DNA literally must stand up to be counted. Understanding both the attachment and orientation of DNA on gold surfaces was the goal of recent experiments performed at ALS Beamline 8.0.1 by an international collaboration of scientists.

Protein Bridges DNA Base and Protein Bridges DNA Base and Nucleotide Excision Repair Pathways Protein Bridges DNA Base and Nucleotide Excision Repair Pathways Print Wednesday, 28 October 2009 00:00 Alkyltransferase proteins (AGT) protect cells from the biological effects of DNA damage caused by the addition of alkyl groups (alkylation). Alkyltransferase-like proteins (ATLs) can do the same, but they lack the reactive cysteine residue that allows the alkyltransferase function, and the mechanism for cell protection has remained unknown. To address this mystery, a British-American team lead by researchers at the Scripps Research Institute recently applied a combination of x-ray structural, biochemical, and genetic studies to ATLs in the yeast Schizosaccharomyces pombe without and with damaged DNA. By showing how a process called non-enzymatic nucleotide flipping activates ATL-initiated DNA repair, their results may improve our understanding of genomic integrity and responses to DNA damage relevant to pathogens and cancer development.

This understanding may lead to better ways of setting limits on human exposure to IR. In spite of the discovery of many mammalian DNA repair genes, our current knowledge of how many of these genes contribute to cellular recovery from IR exposure is quite limited. Project Goals Measure cellular responses at doses in the 5-100 cGy range, which generally cause changes too small to detect in normal, repair-proficient cells Focus on DNA double-strand breaks (DSBs) and DNA oxidative base

Researchers at ALS Beamline 8.3.1 imaged type II topoisomerase's ordinarily short-lived state in which it is linked to a DNA's nucleic acid segment through its active site tyrosine, cleaving the DNA. Details of this molecular model provide evidence for the chemical mechanism by which type II topoisomerases (topo IIs) and a related topo family (topo IA) accomplish DNA cleavage. The structure also reveals how the enzyme avoids dissociating when DNA is cleaved, preventing the aberrant formation of mutagenic genomic lesions.
