To determine the genetic structure, general and specific combining ability of some important agronomic characters, eight rice cultivars including 5 lines and 3 testers were crossed in Rice Research Institute of Iran (RRII), at Rasht, in 2000. Parental lines and F1 were planted in a Randomized Complete Block Design with three replications in the year 2001. Eleven important agronomic traits inclu...
the issue of curriculum and syllabus evaluation and revision has been in center of attention right from when curriculum came into attention of educational institutions. thus everywhere in the world in educational institutions curricula and syllabi are evaluated and revised based on the goals, the needs, existing content, etc.. in iran any curriculum is designed in a committee of specialists and...
Dopaminergic amacrine (DA) cells play multiple and important roles in retinal function. Neurotrophins are known to modulate the number and morphology of DA cells, but the underlying regulatory mechanisms are unclear. Here, we investigate how neurotrophin-3 (NT-3) regulates DA cell density in the mouse retina. We demonstrate that overexpression of NT-3 upregulates DA cell number and leads to a c...
The best performance of a Mach-Zehnder interferometer is achieved with the input state |NT /2+ 1〉|NT /2 − 1〉 + |NT /2 − 1〉|NT /2 + 1〉, being NT the total number of atoms/photons. This gives: i) a phase-shift error confidence C68% = 2.67/NT with ii) a single interferometric measurement. Different input quantum states can achieve the Heisenberg scaling ∼ 1/NT but with higher prefactors and at the...
Facilitate the selection procedure to improve performance of new genotypes of rice is essential. In present study in order to evaluate relationship between grain yields with other agronomic traits, a global rice collection including 100 accessions was seeded in an incomplete block design (triple lattice 10×10). Afterward, grain yield and 14 morphological traits were evaluated. Correlation coeff...
Weed competes with crops for water, nutrients and light so weed infestation is one of the major threats to crop. Present investigation was aimed to asses the comparative efficacy of different herbicides for weed management in wheat crop under agro-climatic conditions of Pakistan. This experiment was laid out in a randomized complete block design (RCBD) design with five replications. Different h...
The role of neurotrophin-3 (NT-3) in early development of the dorsal root ganglion was investigated. Excessive cell death in the dorsal root ganglion of mice that carry a deleted NT-3 gene (NT-3-/- mice) preceded the period of programmed cell death, detected by the TUNEL method, and caused a reduction in the number of proliferating precursors without altering the proportion of proliferating cel...
In order to study the response of rice genotypes to different levels of nitrogen (N), an experiment was conducted to evaluate growth and development of 28 selected rice genotypes (improved and local from north of Iran, and cultivated in Central Iran) under two levels of N including 2.85 mM (N concentration of Yoshida solution) and 1.42 mM (half the N concentration of Yoshida solution) from ammo...
to investigate the yield and agronomic traits of winter bread wheat genotypes in irrigating condition and also to determine the relationship of these traits with grain yield, 15 advanced genotypes of wheat along with three conventional cultivars where studied using randomized complete block design in three replications in 2010 growing season at kheyr-abad agricultural research station. the anal...
A field experiment was conducted during kharif season of 2010 and 2011 to investigate the optimization of nitrogen levels under different age of seedlings transplanted on growth, chlorophyll content, yield and economics of hybrid rice. Fifteen treatment combinations consisted of three levels of seedlings age (10, 20 and 30 days) and five levels of nitrogen viz. N0, N50, N100, N150 and N200 kg h...
