All the real world parameters such as temperature, pressure etc., are analog in nature, In order to control these physical parameters using computers, which are digital in nature, high speed signal processing board is used. This mainly consists of devices such as analog to digital converter, digital to analog converters and timer which perform the interfacing function between analog and digital...

Helicobacter pylori contains a pathogenicity island, cagPAI, with genes homologous to components of the type IV secretion system (T4SS) of Agrobacterium tumefaciens. The T4SS components assemble a structure that transfers CagA protein and peptidoglycan into host epithelial cells, causing the increased release of interleukin 8 (IL8) from the cells. The Toll-like receptors on neutrophils recogniz...

Hurricane Harvey made landfall on the Texas Gulf Coast August 25, 2017, as a Category 4 hurricane and caused widespread flooding. We explored spatial temporal distributions of well testing contamination rates; relationships between system characteristics recovery behaviors; efficacy mitigation strategies. estimated that over 500 000 users (?130 to 260 wells) may have been affected, but only aro...

Subglacial water bodies are critical components in analyzing the instability of Antarctic ice sheet. Their detection and identification normally rely on geophysical remote sensing methods such as airborne radar echo sounding (RES), ground seismic, satellite/airborne altimetry gravity surveys. In particular, RES surveys able to detect basal terrain with a relatively high accuracy that can assist...

It is well known that there are wide varieties of materials which form self-organized structure. When a sort of 3 dimensional network structure is formed, the system may possess viscoelastic properties similar to entangled polymers or gels depending on life time and strength of the structure. A typical example of low molecular weight system is wormlike micelles formed in aqueous solutions of su...

Nuclear magnetic resonance (NMR) spectroscopy analyzes the magnetic properties of an active nucleus for physical and chemical determination. Important information about chemical bonding and molecular structure are provided by chemical shifts (δ) and spin-spin coupling parameters.[1,2] The chemical shift (δ) trends for halogen (X) in different nuclei (Te, C, La, P, etc.) have been investigated e...

The effect of zidovudine (3’-azido-3’-deoxythymidine; AZT) was investigated in four breast cancer cell lines, a T4 cell leukemia, and a normal breast cell line in vitro. AZT inhibited the growth of all tumoral cell lines, but it did so in a wide range of concentrations. The growth of a normal breast cell line was also inhibited, although it required a much higher concentration. Furthermore, AZT...

Background/Aims: Currently available techniques for fluoride analysis are not standardized. Therefore, this study was designed to develop standardized methods for analyzing fluoride in biological and nonbiological samples used for dental research. Methods: A group of nine laboratories analyzed a set of standardized samples for fluoride concentration using their own methods. The group then revie...
