For the past century, biologists have attempted to identify and document qualitative properties that underlie molecular binding processes in living cells. Cooperativity in the binding processes represents a primary and highly general mechanism for achieving the collective behaviour that emerges in systemslevel properties of macromolecules, pathways, cells and organisms. Recent progress in robot...

Satellite-derived retrievals of precipitation have increased in availability and improved in quality over the last decade. There are now several satellites in orbit with instruments capable of precipitation retrieval with various degrees of accuracy, spatial resolution and temporal sampling. These retrievals have the advantage of almost full global coverage when compared to surface gauges and g...

The distribution of mucosa-associated bacteria, bifidobacteria and lactobacilli and closely related lactic acid bacteria, in biopsy samples from the ascending, transverse, and descending parts of the colon from four individuals was investigated by denaturing gradient gel electrophoresis (DGGE). Bifidobacterial genus-specific, Lactobacillus group-specific, and universal bacterial primers were us...

In this paper, the impacts of the uncertainty of fuel heating value as well as the burner efficiency on performance functions of a turbofan engine are studied. The mean value and variance curves for thrust, thrust specific fuel consumption as well as propulsive, thermal and overall efficiencies are drawn and analyzed, considering the aforementioned uncertainties based on various Mach numbers at...

This paper is aimed at serving the needs of structural engineering researchers who are seeking accelerograms that realistically represent time histories earthquake ground in support their own investigations. Every record identified with a specific scenario defined by magnitude–distance combination and site conditions; intensity presented records consistent ultimate limit state design requiremen...

conclusions the aspirates from the hypovascular and hypervascular sites of solid nodules are complementary and should be performed consecutively. results when only hypervascular site was used, adequate sampling was limited to 65% of the cases. when both sites were evaluated together, overall adequate sampling was 91%. adding a sample from the hypervascular site to hypovascular aspirate increase...
