scarce water resources is a worldwide problem, still for iran, a country predominated by an arid and semi-arid climate, water limitation is more severe than for many other areas of the world. a field experiment was conducted to investigate the impact of irrigation regimes on growth, grain yield and irrigation water use efficiency in maize (zea maize l.) in 2006 at the research farm, college of ...

We present an adaptive mimetic finite difference method for the approximate solution of variational inequalities. The adaptive strategy is based on a heuristic hierarchical type error indicator. Numerical experiments that validate the performance of the adaptive MFD method are also presented. 1 The Obstacle Problem Throughout the paper we will use standard notations for Sobolev spaces, norms an...

Toxplasmosis is an important zoonotic disease caused by protozoan parasite Toxoplasma gondii. Transmission of the disease is mainly by ingestion of food or water contaminated with oocysts. Congenital toxoplasmosis occurs from the transplacental passage of from mother to fetus. Diagnosis of toxoplasmosis can be established by the direct detection of the parasite or serological methods. Among 150...

Oxidation of dihydrorhodamine 123 (DHR) to rhodamine 123 (RH) by oxoperoxonitrite (ONOO(-)), formed through recombination of NO and O(2)(·-) radicals resulting from thermal decomposition of 3-morpholinosydnonimine (SIN-1) in buffered aerated aqueous solution at pH 7.6, represents a kinetic model system of the reactivity of NO and O(2)(·-) in biochemical systems. A magnetic-field effect (MFE) on...
