Nitrogen has an important role for supplying carbon skeletons which needs for producing compatible solutes and stress tolerance enzymes. Water deficit affects nitrogen fixation in legums. So we studied the effect of various nitrogen sources on physiological, and biochemical features of bean under water stress. This experiment was conducted as factorial based on completely randomized design with...
The economic and environmental losses due to serious leakage in the urban water supply network have increased the effort to control the water leakage. However, current methods for leakage estimation are inaccurate leading to the development of ineffective leakage controls. Therefore, this study proposes a method based on the blind source separation theory (BSS) to calculate the leakage of water...
Several lines of evidence have been examined in attempts to implicate potable water as a source for legionellosis. Success has been mixed. The strongest evidence has been the similarity of strains recovered from patients and from potable water and the cessation of outbreaks following institution of measures to eradicate Legionella from potable water systems. Epidemiologic efforts to identify th...
