to study the effects of different levels of water stress and nitrogen fertilizer on seed yield and yield components of two common bean genotypes (phaseolus vulgaris), an experiment in a split plot factorial based on crbd with four replications was conducted at the research farm of university of tehran (karaj-iran) in 2010. water stress treatments as the main factor included normal irrigation (6...

The main impetus for our research is provided by the growing interest worldwide in ultra thin silicon dioxide on silicon based nano devices. The obvious need for better knowledge in the ultra thin gate silicon dioxides, is motivated both by interests in fundamental research and phenomenology as well as by interests in possible applications, which can be found with better fitting of experimental...

The purpose of this study was to contribute to the construct validity of the scores from Rose’s (2003) 34-item Ideal Mentor Scale (IMS) and to examine whether male and female doctoral students value different attributes in their ideal mentor. Two hundred and twenty-four doctoral students from colleges (Education, Public Health, Nursing, Arts and Sciences, Engineering, and Business) throughout a...

The choice of substrate orientation for semiconductor quantum dot circuits offers opportunities tailoring spintronic properties such as g-factors specific functionality. In this letter, we demonstrate the operation a few-electron double circuit fabricated from (110)-oriented GaAs well. We estimate in-plane electron g-factor profile enhanced inter-dot tunneling (leakage) current near zero magnet...

Cytochrome c-554 functions in the ammonia oxidizing system of Nitrosomonas europaea. We have investigated its molecular and ligand binding properties and studied the protein with optical, EPR, and Mössbauer spectroscopies in the pH range from 2 to 13. Amino acid, heme, and metal analyses show that the protein has Mr = 25,000 and that it contains four c-type hemes per molecule. Optical spectra r...
