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 ...

Breast cancer survivors are at life-time risk of developing lymphedema (LE). Quantification of LE has been problematic as the criteria used to identify lymphedema use various methods to assess changes in the volume of the affected limb. In part because of difficulties and variability in measurement and diagnosis, the reported incidence of LE varies greatly among women treated with surgery and r...

B lymphocytes and certain subpopulations of T lymphocytes respond to stimulation with antigen by synthesis and secretion of unique glycoproteins capable of binding the stimulating antigen. In the case of the B cell, these glycoproteins are the classic antibody molecules, which have been well characterized in terms of structure, function, and organization, both at the protein and nucleic acid le...

yekta was created in 1981 from crossing between b5 ? m7 and an early maturing palistinian line, in oil seed crops research department of seed and plant improvement institute (spii) at karaj. the pure line of the cross was obtained after five years of selection with pedigree method. preliminary evaluation of the line along with other 31 selected lines was done in 1989 and yekta together with oth...

Interferometric tests of a f/1.2 2.5-m diameter liquid mirror show RMS surface deviations ̃ λ/20 and Strehl ratios of order 0.6, showing that it is diffraction limited. The mirror is certainly better than implied by the data because of aberrations introduced by the auxiliary testing optics. We have made detailed studies of the scattered light of the mirror. We have studied the behavior of the m...

We construct a mid-latitude (30–60 N) reduced temperature-depth profile from a global borehole temperature database compiled for climate reconstruction. This reduced temperature profile is interpreted in terms of past surface ground temperature change and indicates warming on the order of 1C over the past 100 to 200 years. The combination of an initial temperature (the primary free parameter) w...
