water quality aspect with regard to dissolved oxygen was studied for a 24 kilometer stretch of malaprabha river in karnataka state, india. main objective of the research was to simulate the predicted dissolved oxygen depletion due to the waste load allocation in the river with the ambient observed values of dissolved oxygen, and to ascertain the application of mathematical modeling for predicti...

The decorrelation stretch is a process that is used to enhance (stretch) the color differences found in a color image. The method used to do this includes the removal of the inter-channel correlation found in the input pixels; hence, the term "decorrelation stretch". The purpose of this document is to explain: 1) the conditions that normally appear in multispectral data that indicate that color...

Whereas endothelial responses to shear stress have been studied extensively, the responses to circumferential vascular stretch are yet poorly defined. Circumferential stretch in pulmonary microvessels is largely determined by the transmural pressure gradient, hence by both vascular perfusion and alveolar ventilation pressures. Here, we have studied the production of nitric oxide (NO) by the end...

Ventilation of septic patients often leads to the development of edema and impaired gas exchange. We hypothesized that septic alveolar epithelial monolayers would experience stretch-induced barrier dysfunction at a lower magnitude of stretch than healthy alveolar epithelial monolayers. Alveolar epithelial cells were isolated from rats 24 hours after cecal ligation and double puncture (2CLP) or ...

In this paper, we investigate the tight bound of the stretch factor of the Delaunay triangulation by studying the stretch factor of the chain (Xia 2011). We define a sequence Γ = (Γ1,Γ2,Γ3, . . .) where Γi is the maximum stretch factor of a chain of i circles, and show that Γ is strictly increasing. We then present an improved lower bound of 1.5932 for the stretch factors of the Delaunay triang...

OBJECTIVES Myostatin, a negative regulator of muscle growth, is increased in hypertrophied and infarcted heart. However, the mechanism of regulation is not known. Mechanical stress is an important regulatory factor for cardiomyocyte growth. The aim of the study was to investigate the effect of cyclic stretch on the expression of myostatin gene in cardiomyocytes. METHODS Neonatal Wistar rat ca...
