Theoretical and simulation tools for electron transfer and chain reactions in single walled carbon nanotubes
… interest is the concept of nanostructure-guided chain reactions, wherein the superior thermal conductivity of a nanotube is used to anisotropically enhance the combustion velocity of the energetic moiety covalently attached to its sidewall. A molecular assembly with this property has the …

Kinetics and mechanism of alpha-chymotrypsin catalyzed reactions.
… reversibility was formulated for elementary reactions at equilibrium. It follows from the principle that for any elementary reaction the favored reaction path in one direction must be the reverse of that in the opposite reaction, and that the ratio of rate constants is the equilibrium …

HIV transmission to transmission to premature very low birth weight infants
… preterm infants received birth polymerase chain reactions (PCRs). Five (6.1%) were HIV positive with all 5 mothers receiving inadequate antiretrovirals. Of the PCRnegative infants, 9 died and 87% of the survivors received further PCR testing which remained negative. With correct care, …

Combination of Dietary Tomato and Broccoli Powders Are Effective Growth Inhibitors of Dunning R3327-H Prostate Adenocarcinomas
… respectively. Utilizing real time polymerase chain reactions (RT-PCR) and the SYBR Green assay, mRNA was quantified in the liver, prostate, and tumors. Finasteride significantly decreased expression of 5-alpha-reductase-II, Bcl-2, and IL-6 in tumors. IL-6 was reduced in high lycopene and …

Identification and characterisation of bacterial genes associated with resistance to and/or degradation of environmental pollutants
… to varying levels of heavy metals and polymerase chain reactions suggesting the presence of mercury (mer), copper (pco) and cadmium, zinc and cobalt (czc) resistance genes. S. maltophilia VUN 10010, was previously investigated for its ability to degrade pyrene and other HMW PAHs as a sole carbon …

Helium-Air mixing in simulated reactor cavities of Very High Temperature Reactors
… as a moderator to slow down neutrons for fission chain reactions and for general core support. In the event of a primary circuit pipe break, the coolant gas escapes into the surrounding reactor cavity until the pressure between the reactor pressure vessel (RPV) and cavities equalize. At this …

Contraction analysis of nonlinear systems
… robots. The method is also applied to chemical chain reactions and mixture processes. The relative simplicity of these designs stems from their effective exploitation of the systems' structural specificities. Next, we analyze and quantify the global stability properties of physical partial …

Patterns in the Presence of Respiratory Tract Mycoplasmas in Four Species of North American Tortoises
… of mycoplasmas using quantitative polymerase chain reactions (qPCR) on DNA extractions from nasal flushes. The qPCR process showed that both Mycoplasma pathogens were present in the four species of tortoises. Statistical analyses indicated that "species" and "sample site" were significantly …

Analysis of the Expression Profiles of Two Isoforms of the Antifungal Protein Osmotin from Gossypium hirsutum
… chloride. Reverse transcriptase-polymerase chain reactions (RT-PCR) indicated that osmotin mRNAs are expressed constitutively in root tissues of cotton plants, and that they are rapidly induced in leaf and stem tissues upon ethylene treatment. Real time RT-PCR indicated that osmotin …

Molecular characterization of trypanosomes commonly found in cattle, wild animals and tsetse flies in Kwazulu-Natal, South Africa, 2005-2007
… genome were used in conducting polymerase chain reactions (PCRs) on samples collected from cattle at 14 diptanks and one commercial farm around the Hluhluwe-Umfolozi Game Reserve, wild animals within Hluhluwe-Umfolozi Game Reserve and tsetse flies from the commercial farm, Hluhluwe-Umfolozi …

Arrangement of minors in the positive Grassmannian
… minors which are not weakly separated using chain reactions of mutations of plabic graphs. In the second chapter, we investigate arrangements of tth largest minors and their relations with alcoved triangulation of the hypersimplex. We show that second largest minors correspond to the facets …

ADVANCED APPLICATIONS OF COSMIC-RAY MUON RADIOGRAPHY
… that can indicate the presence of fission and chain reactions. By combining the radiographic images created by tracking muons through a target plane with the additional fission neutron and gamma signature, we are able to locate regions that are fissionable from a single side. The following …

CFD Simulation of Combustion Using Automatically Reduced Reaction Mechanisms : A Case for Diesel Engine
… from the ILDM chemistry. Low-temperature reactions lead to the slow formation of a radical pool after the fuel is injected in the engine. The concentration of this radical pool increases during the ignition-delay period due to chain reactions. After a critical mass of radicals is formed, …

Characterizing methanogen and methanotroph diversity, abundance and activity within the Hampshire-Avon catchment
… measurements, quantitative real-time polymerase chain reactions (Q-PCR) of pmoA, mcrA genes and next generation sequencing, were applied to characterize methanogen and methanotroph community structure, abundance and activity in the Hampshire-Avon catchment, UK. Soil and river sediments were taken …
