Title: Technology disrupted

Abstract

Three years ago, the author presented a report on power generation technologies which in summary said 'no technology available today has the potential of becoming transformational or disruptive in the next five to ten years'. In 2006 the company completed another strategic view research report covering the electric power, oil, gas and unconventional energy industries and manufacturing industry. This article summarises the strategic view findings and then revisits some of the scenarios presented in 2003. The cost per megawatt-hour of the alternatives is given for plants ordered in 2005 and then in 2025. The issue of greenhouse gas regulation is dealt with through carbon sequestration and carbon allowances or an equivalent carbon tax. Results reveal substantial variability through nuclear power, hydro, wind, geothermal and biomass remain competitive through every scenario. Greenhouse gas scenario analysis shows coal still be viable, albeit less competitive against nuclear and renewable technologies. A carbon tax or allowance at $24 per metric ton has the same effect on IGCC cost as a sequestration mandate. However, the latter would hurt gas plants much more than a tax or allowance. Sequestering CO{sub 2} from a gas plant is almost as costly per megawatt-hour as for coal. 5 refs.,more » 5 figs., 5 tabs.« less

  • Fibroblasts obtained from biopsy material and lymphocytes of patients with homocystinuria were investigated for repair activity according to the following criteria: rejoined DNA breaks, induced by 4-nitroquinoline-1-oxide and ..gamma..-radiation; indices of reactivation and induced mutagenesis of smallpox vaccine virus treated with these mutagens. In lymphocytes a defect of DNA repair was observed according to all criteria investigated. During passage of fibroblast cultures, inhibition of repair activity of cells was preserved according to ..gamma..-type. Increase in the number of spontaneous and ..gamma..-induced mutations of virus was noted according to degree of passage of fibroblasts.
  • Plasma diffusion is analyzed in the case in which the system of magnetic surfaces is disrupted by a stochastic perturbation of the magnetic field. The diffusion coefficient is related to the statistical properties of the field. The statistical characteristics of the field are found when the magnetic surfaces near the separatrix are disrupted by an external perturbation. The diffusion coefficient is evaluated in the region in which the magnetic surfaces are disrupted. In this region the diffusion coefficient is of the Bohm form.
  • The margin to criticality of selected distorted core configurations derived from the hypothetical loss of shutdown cooling accident in a 300-MW(electric) gas-cooled fast reactor has been investigated using two-dimensional transport theory. Configurations representing crumbled cores declad fuel columns in nearly intact geometry, and partial slumping of the fuel on the core floor with subsequent radial spreading have been studied. Three minimum postulated conditions for recriticality have been identified for the configurations characterized by declad fuel in nearly intact geometry: If the fuel is fully compacted (no spaces among the crumbled fuel pieces), then 55% of the fuel rods in themore » core must crumble for recriticality. If 65% of the volume in the crumbled fuel region is space occupied by fuel, then 46% of the fuel rods must be crumbled (with the remaining 54% standing erect but declad). If 28% of the volume in the crumbled fuel bed is space occupied by fuel, then 82% of the rods must crumble for recriticality. For cores that are postulated to melt and slump in a radially outward progression, the reactivity changes from a ''safe shutdown'' with K /SUB eff/ = 0.93 to supercritical with K /SUB eff/ = 1.103. If the compact, but molten, core spreads radially outward, the reactivity decreases to K /SUB eff/ = 1.041.« less
  • Meningiomas are tumors of the central nervous system in which loss of heterozygosity for markers on the long arm of chromosome 22 is a frequent event. We have previously described a balanced t(4;22)(p16;q11), which was observed in meningioma 32. We have cloned a gene (MN1), which is disrupted by the translocation breakpoint. The gene spans about 70 kb on chromosome 22q11. A total of 7.5 kb of overlapping cDNA clones were isolated. A comparison of the cDNA clones with the genomic cosmid contig from this region shows that the MN1 gene consists of at least two large exons of approximatelymore » 4.7 kb and 2.8 kb. Sequence analysis of the MN1 cDNA revealed two open reading frames (ORFs) of 1 and 2.3 kb which are separated by a region of approximately 1 kb with stop codons in all reading frames. The second ORF is disrupted by the t(4;22) translocation. In the region between the ORFs 2 CAG repeats have been found. These repeats do not display length variation in meningiomas. There is no obvious homology in the nucleotide and putative amino acid sequences with other known genes. The MN1 gene is highly conserved in evolution. The approximately 8 kb MN1 mRNA is ubiquitously expressed with an alternative 4.5 kb transcript in skeletal muscle. In meningiomas the expression pattern is very variable and a 6.5 kb transcript is sometimes also observed. Some, including meningioma 32, show no expression suggesting that the gene could function as a tumor suppressor gene for meningeal cells. Paradoxically, however, a very high expression is sometimes also observed in meningiomas.« less
