A comparison of the central processing unit (CPU) time and storage requirements for the parallel and deductive fault simulation techniques is presented. Versions of a parallel and deductive simulator were implemented and the comparison performed on an IBM System/360 Model 67 by simulating representative circuits including shift registers, sequencers, counters, two memory units, and a processor....
RPM is a package management system which provides a uniform, automated way for users to install, upgrade, and uninstall programs. Because RPM is the default software distribution format for many operating systems (particularly GNU/Linux), users may find it useful to manage their library of TEXrelated packages using RPM. This article explains how to produce RPM files for TEX software, either for...
The synthesis and characterization of a new photolabile protecting group (caging group) for carboxylic acids, the 2-(dimethylamino)-5-nitrophenyl (DANP) group, is described. This compound has a major absorption band in the visible wavelength region with a maximum near 400 nm (epsilon400 = 9077 M(-1) cm(-1) at pH 7.4 and 21 degrees C). The caging group is attached through an ester linkage to the...
Nicotine withdrawal (NW) is both an important contributor to difficulty quitting cigarettes and because of mood-related withdrawal symptoms a problem of particular relevance to psychiatry. Twin-studies suggest that genetic factors influence NW (heritability = 45%). Only one previous linkage study has published findings on NW [Swan et al. (2006); Am J Med Genet Part B 141B:354-360; LOD = 2.7; Ch...
Changes in axon outgrowth patterns are often associated with synaptogenesis. Members of the conserved Pam/Highwire/RPM-1 protein family have essential functions in presynaptic differentiation. Here, we show that Caenorhabditis elegans RPM-1 negatively regulates axon outgrowth mediated by the guidance receptors SAX-3/robo and UNC-5/UNC5. Loss-of-function rpm-1 mutations cause a failure to termin...
Among the known processes for production of acetone, most promising is synthesis by hydration acetylene in presence catalysts. The advantage this method possibility carrying out process existing acetaldehyde plants. On other hand, simultaneous and acetone under action polyfunctional catalysts implementation using flexible technology promising. To study influence various factors on obtaining cat...
Determining the earliest age at which farmed fish can be successfully vaccinated is a very important question for fish farmers. Nasal vaccines are novel mucosal vaccines that prevent aquatic infectious diseases of finfish. The present study investigates the ontogeny of the olfactory organ of rainbow trout by histology and aims to establish the earliest age for vaccination against infectious hem...
In this study, the fracture behavior of AISI 4140 low-alloy steel nitrided with respect to applied current density was investigated. A series rotary bending fatigue tests were performed various loads (350, 400, 450, and 500 N) at a constant rotational speed 2000 rpm. The results show that increase in strength (up 35%) strongly depends on compound layer formed during nitriding process. addition,...
Dehalococcoides ethenogenes strain 195 reductively dechlorinates tetrachloroethene (PCE) and trichloroethene (TCE) to vinyl chloride and ethene using H2 as an electron donor. PCE- and TCE-reductive dehalogenase (RD) activities were mainly membrane associated, whereas only about 20% of the hydrogenase activity was membrane associated. Experiments with methyl viologen (MV) were consistent with a ...
