This research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. This experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of Chenran Township. The results ...

In many geodetic applications a large number of observations are being measured to estimate the unknown parameters. The unbiasedness property of the estimated parameters is only ensured if there is no bias (e.g. systematic effect) or falsifying observations, which are also known as outliers. One of the most important steps towards obtaining a coherent analysis for the parameter estimation is th...

abstract- a real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. the image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. the image frames were processed by labview® and matlab®. the developed algorithm, based on weed coverage ratio and seg...

introduction: endothelial cells are subjected to mechanical forces caused by pulsatile flow and pressure leading to hemodynamic shear stress and circumferential stress on endothelial layer. the study aimed at a quantitative evaluation of endothelial cell morphology by application of cyclic loading. endothelial cells respond to applied loads with adaptation and remodeling. such mechanisms are ma...

Cyclic circumferential stretch and shear stress caused by pulsatile blood flow work in concert, yet are very different stimuli capable of independently mediating endothelial function by modulating eNOS expression, oxidative stress (via production of superoxide anion) and NO bioavailability. Porcine carotid arteries were perfused using an ex vivo arterial support system for 72 h. Groups we creat...
