NASS/CDS delta-V estimates: the influence of enhancements to the WinSmash crash reconstruction code.
The change in velocity (delta-V) crash severity metric in the NASS/CDS (National Automotive Sampling System / Crashworthiness Data System) is computed using the WinSmash crash reconstruction code. Beginning in 2008, NASS/CDS investigators have started to use an enhanced version of WinSmash, WinSmash 2008, which features a comprehensive vehicle specific library for over 5000 vehicle make-model-y...
Introduction: Methamphetamine consumption is associated with cognitive and neuropsychological damage. Determining the effect of this substance on the activities and characteristics of the human brain can lead to the prevention and treatment of complications caused by abuse. There are diverse chemical formulas in Iran with unknown properties. Moreover, few studies have focused on electrophysiolo...
The stress of motion sickness was experimentally provoked by Coriolis effect. Significant and reproducible increases from the basal serum level (delta mean +/- S.E.) of antidiuretic hormone delta - ADH: 48.2 +/- 4.6 pg/ml; p less than 0.0005), of growth hormone (delta - hGH: 10.0 +/- 1.2 ng/ml; p less than 0.0005), of prolactin (delta - hPRL: 186.5 +/- 29.9 muU/ml; p less than 0.0005), and of c...
We report a simulation study of the gas-liquid critical point for the square-well potential, for values of well width delta as small as 0.005 times the particle diameter sigma. For small delta, the reduced second virial coefficient at the critical point B2*c is found to depend linearly on delta. The observed weak linear dependence is not sufficient to produce any significant observable effect i...
Two new oxides have been unambiguously identified as Bi2Tc2O7-delta with delta = 0.14(1) and Bi3TcO8 through X-ray absorption near-edge structure spectroscopy and neutron powder diffraction. The compound Bi2Tc2O7-delta has a cubic pyrochlore-type structure with a = 10.4746(1) A, space group Fd3m (origin choice 2), and Z = 8. The compound Bi3TcO8 is also cubic, a = 11.5749(1) A, space group P2(1...
The joining of single-stranded breaks in double-stranded DNA is an essential step in many important processes such as DNA replication, DNA repair, and genetic recombination. Several data implicate a role for DNA ligase I in DNA replication, probably coordinated by the action of other enzymes and proteins. Since both DNA polymerases delta and epsilon show multiple functions in different DNA tran...
Lens development is regulated by a variety of transcription factors with distinct properties. The lens-specific transcription factor, L-Maf, is essential for lens formation and induces lens-specific markers, such as the crystallin genes. In this study, we analyzed the mechanism by which L-Maf regulates delta-crystallin expression. Misexpression of L-Maf in the head ectoderm of lens placode-form...
BTN1 of Saccharomyces cerevisiae encodes an ortholog of CLN3, the human Batten disease gene. We have reported previously that deletion of BTN1, btn1-Delta, resulted in a pH-dependent resistance to D-(-)-threo-2-amino-1-[p-nitrophenyl]-1,3-propanediol (ANP). This phenotype was caused by btn1-Delta strains having an elevated ability to acidify growth medium through an elevated activity of the pla...
