genotype by environment interaction is one of the most important subjects in crop improvement, so that different statistical measures have been proposed to estimate this interaction. in the present study, nine varieties and hybrids of spring rapeseed were evaluated in five warm dryland areas including sarpol-e-zahab, gonbad, gachsaran, pol-e-dukhtar and masjedsoliman in two growing seasons 2002...

In situ ordering of FePt thin films by sputtering onto Ag/Si and Ag/Mn3Si/Ag/Si templates has been demonstrated. Due to the evolution from island-like to a continuous film structure as a function of Ag thickness, the ordering and orientation of the FePt films both change with Ag thickness. A continuous (002) Ag film results in a greater L10 phase formation with -axis oriented both perpendicular...

Sucrase-isomaltase (SI) expression along the longitudinal and vertical axis of the small intestine was studied by sequentially isolating enterocytes from villus to crypt of rat proximal jejunum and distal ileum. Gradients of sucrase activity were observed with greatest activity occurring in jejunal and villus regions. Along the villus-to-crypt axis, gradients of SI mRNA abundance corresponded w...

We review our recent achievements in monolithic 3D-ICs and flexible electronics based on single-grain Si TFTs that are fabricated inside a single-grain with a low-temperature process. Based on pulsedlaser crystallization and submicron sized cavities made in the substrate, amorphous-Si precursor film was converted into poly-Si having grains that are formed on predetermined positions. Using the m...

Graphene, the first discovered 2D Dirac material, has had a profound impact on science and technology. In the last decade, we have witnessed huge advances in graphene related fundamental and applied research. Here, based on first-principles calculations, we propose a new 2D Dirac band on the Si(111) surface with 1/3 monolayer halogen coverage. The sp(3) dangling bonds form a honeycomb superstru...

Let s/* = {l\,li, ■■■ , ln} be a line arrangement in CP2 , i.e., a collection of distinct lines in CP2 . Let L(s/ * ) be the set of all intersections of elements of A* partially ordered byX<Y&YCX.Let M{tf*) be CP2 U-af* where \Jsf* = lj{'i: !<'<"}• The central problem of the theory of arrangement of lines in CP2 is the relationship between M{stf * ) and L{s/*). Main Theorem. The topological typ...

Background: The Trauma is one of the most important health problems and a leading cause of death in 4th decade of life. Mortality due to accidents has a critical situation in Iran and mortality rate is increasing10-15% annually. Aim: To assess the relationship of shock index with trauma patient’s mortality after first 24 hours of admission at Khatam-al-Anbia Hospital in Iranshahr. Method A cros...

We present (29)Si, (27)Al, and (67)Zn NMR evidence to show that silicate ions in alkaline solution form complexes with zinc(II) (present as zincate, Zn(OH)(3)(-) or Zn(OH)(4)(2-)) and, concomitantly, with aluminate (Al(OH)(4)(-)). Zincate reacts with monomeric silicate at pH 14-15 to form [(HO)O(2)Si-O-Zn(OH)(3)](4-) and with dimeric silicate to produce [HO-SiO(2)-O-SiO(2)-O-Zn(OH)(3)](6-). The...

Purpose We identify noninvasive biomarkers that measure the severity of oxidative stress within retina layers in sodium iodate (SI)-atrophy vulnerable (C57BL/6 [B6]) and SI-atrophy resistant (129S6/SvEvTac [S6]) mice. Methods At 24 hours after administering systemic SI to B6 and S6 mice we measured: (1) superoxide production in whole retina ex vivo, (2) excessive free radical production in vi...
