Fluoride levels were determined in roots, stalks, and leaves of common underwater reeds (Phragmites australis) harvested in 2001 from a polluted reservoir near Luboń and an unpolluted reservoir near Radzewice, Poland. The mean fluoride concentrations in the roots, stalks and leaves of the polluted reservoir were, respectively, 213, 36.8, 51.1 mg F/kg dry mass. In the unpolluted reservoir they w...
In order to evaluate the productivity potential of some bread wheat varieties and promising lines under no-till rainfed condition two different on-farm trials were conducted in cold (Sonqor) and warm (Sarpol-e Zahab) regions of Kermanshah province during 2017-18 cropping season. In the cold condition, 12 winter genotypes and in the warm condition 32 spring genotypes were evaluated for grain ...
two glasshouse and field experiments were conducted to assess the effects of root system, water uptake, water use efficiency and early vigor on yield and drought tolerance of bread wheat in two successive farming seasons (2009-11). the experiments were conducted as randomized complete block design and two-year results analyzed as combined design. considerable genetic variation was observed amon...
In order to estimate the heritability of morphological characters of worker honey bee and honey yield, 30 queen-mothers were selected randomly from the apiary of Research Center of Animal Science and Natural Resources in Isfahan Province. From each queen-mother, five queen-daughters were reared and introduced to equalize colonies after natural mating of queens. Summer honey yield was measured, ...

To estimate heritability and association between traits traits, 148 recombinant inbred lines and their parents (Yecora Rojo and No. 49) were evaluated in Alfa lattice design with two replications under normal and water deficit conditions during two cropping season (2013-15). Results showed that there were significant differences between genotypes for all studied traits. The estimated herit...
relationship between grain yield and its component traits can improve the efficiency of breeding programs by determining appropriate selection criteria. an investigation was carried out on barnyard millet (echinochloa spp.) global germplasm collection to investigate the association among yield components and their direct and indirect effects on the grain yield of barnyard millet. the experiment...
Castor is one of neglected African oil crops with little research attention in Nigeria. In the present research, eighty-six castor genotypes were evaluated at three locations in Niger State, Nigeria. The aim was to estimate the extent of genetic variability and also to examine the associations among the seed yield and its components. The treatments were laid out in an Alpha Lattice Design with ...
با پیشرفت تکنولوژی و کاهش ابعاد ترانزیستور، تلرانس پارامترهای ساخت مدارات الکترونیک افزایش یافته و باعث کاهش ضریب yield می شود. در طراحی مدارات الکترونیک، طراح عموما مقادیر نامی را برای دست یابی به عملکرد مطلوب استخراج می کند، در حالی که، در عمل یک ناحیه تلرانس، به دلیل فرآیند های تصادفی حین فرآیند های ساخت، وجود دارد که بایستی در طراحی لحاظ گردد. الگوریتم های بهینه سازی طراحی تلرانس، ناحیه تلر...
