One of the possible ways to ensure future food needs of an increasing world population involves the better water use through the development of crop varieties which need less water and are more tolerant to drought. In order to study the response of twenty landraces of bread wheat to drought stress, an experiment was conducted in a randomized complete block design with three replications under t...

  The salinity tolerance, hematological and hydromineral regulation capabilities of juvenile Russian sturgeon (Acipenser gueldenstaedtii) were investigated in different ages and sizes in freshwater (FW: <0.5‰), estuary water (EW: 9.5‰) and Caspian Sea water (CSW: 12.5‰). The fish were directly transferred from FW to EW and CSW. The possible repercussions of ion-osmoregulatory processes on some ...

This paper constructs an adaptive algorithm for ordinary differential equations and analyzes its asymptotic behavior as the error tolerance parameter tends to zero. An adaptive algorithm, based on the error indicators and successive subdivision of time steps, is proven to stop with the optimal number, N , of steps up to a problem independent factor defined in the algorithm. A version of the alg...

The objectives of this work were (1) to screen large collection of bean genotypes for salinity responses and (2) to identify the best traits for screening the bean germplasm in tolerance to salt stress. Sixty-four bean genotypes were subjected to 125 mM NaCl. Plants were grown in hydroponic growing medium in greenhouse. The screening was carried out at early growing stage (25 days old plant). I...

After a sublethal exposure to lipopolysaccharide (LPS) or to lipid A, which is that portion of the LPS molecule associated with endotoxicity, a transient period ensues during which a normally responsive individual is rendered hyporesponsive to LPS-induced toxicity. This period has been defined as early-phase endotoxin tolerance. Recently, a nontoxic derivative of lipid A from Salmonella typhimu...
