A Synthetic Signal Varied Weight Indicator in Bacteria

A Survey on Drinking Water Contamination to Indicator Bacteria in Dairy Farms of Mashhad Suburb

BACKGROUND: Microbial quality of drinking water is very important in animal health. OBJECTIVES: The present survey was conducted to evaluate the microbial quality of cows' drinking water in dairy farms in Mashhad suburb, Iran, to find out defects in this field. METHODS: Water samples were taken from 30 farms and 4 sites including: Water tanks,  inlet and outlet  of bovine drinking troughs and c...

Spatially Varied Flow Profiles in a V-Shaped Side-Channel

Molecular Modeling Study of Various Synthetic Jhas Containing Varied Functionality

Virtual screening emerged as an important tool in our quest to access novel pesticides like compounds. The capability to propose feasible ways of binding a putative ligand to a known receptor site is crucial to the structure – based drug design. Molecular docking is one of the most important methods in computer assisted screening of compounds. A docking approach is to “dock” ligand and receptor...

Dissolution of biogenic and synthetic UO2 under varied reducing conditions.

The chemical stability of biogenic UO2, a nanoparticulate product of environmental bioremediation, may be impacted by the particles' surface free energy, structural defects, and compositional variability in analogy to abiotic UO(2+x) (0 < or = x < or = 0.25). This study quantifies and compares intrinsic solubility and dissolution rate constants of biogenic nano-UO2 and synthetic bulk UO2.00, ta...

Chemotactic signal integration in bacteria.

Chemotactic signaling in Escherichia coli involves transmission of both negative and positive signals. In order to examine mechanisms of signal processing, behavioral responses to dual inputs have been measured by using photoactivable "caged" compounds, computer video analysis, and chemoreceptor deletion mutants. Signaling from Tar and Tsr, two receptors that sense amino acids and pH, was studi...
