Work under this investigation included farm survey, extension, and research components using both the CLSU research station and demonstration farms. An experiment was conducted for the determination of optimal stocking sizes, considering the growth and survival performance of various sizes of fingerlings along with economic factors. Size #22 sex-reversed nursery phase fingerlings of Nile tilapi...
Katoul is a new soybeam cultivar originated from a genotype named D.P.X.3589 imported from the United States of American in 1990. This genotype was examined together with other soybean genotypes and check cultivars in different preliminary and advanced yield traits in Gorgan and other research stations during 1999-2002. The mean seed yield of D.P.X.3589 in all these experiments was 3333 kgha-1 ...
Spirometry is the most frequently performed lung function test. To determine a normal range of spirometry results, reference formulas are used. Predicted values play an important role in establishing whether the volumes measured in an individual fall within a range to be expected in a healthy person of the same gender, height, and age. Such standards enable to assess the development of the resp...
Introduction In this note a scheme for the collection, phase rotation and cooling of muons for a neutrino factory is reported. The scheme is sufficiently generic to be site independent also if some particular choices are influenced by the CERN design. The system discussed in this note is worked on as a possible alternative to the induction linac scheme [1]. The results presented assume the foll...
water deficit stress is the most important environmental constraint for growth, yield and productivity of crops, including the oil seed crops. this study was aimed at studying the influence of differing irrigation régimes on growth, chlorophyll , proline and some antioxidants content along with grain yield, yield components and oil content of sesame genotypes using a 4-replicate split plot rand...
In order to evaluate the effect of different levels of nitrogen on yield, yield components and some quality characteristics of two cultivars of rapeseed, a field experiment was conducted in Dezfoul, southwest of Iran during 2011-2012. The experimental design was a split plot in a randomized complete block design with four replications. Nitrogen levels (0, 80, 160 and 240 kg ha-1) were the main-...
A new, efficient and mild method for the direct oxidation of selenides to selenones using magnesium bis(monoperoxyphthalate) hexahydrate (MMPP) has been developed. Noteworthy this transformation proceeds at room temperature, employs a cheap and safety oxidant and has a broad functional group tolerance. Moreover, the produced selenones could be useful intermediates for the synthesis of different...
تئوری نانوسیال اولین بار توسط چویی در سال 1995 ارائه شد و نانوسیالات نوع جدیدی از سیال ها هستند که از پراکندگی نانوذرات جامد در سیال پایه همچون آب، اتیلن گلیکول و روغن موتور ساخته می شوند. در بخش اول کار، از شبکه پس انتشار (bpn) و تجزیه و تحلیل مولفه های اصلی (pca) به منظور پیش بینی ویسکوزیته ی موثر نانولوله کربن استفاده شده است. ویسکوزیته ی سوسپانسیون نانولوله کربن به عنوان تابعی از دما، کسر ح...
in order to investigate the effects of different levels of nitrogen and phosphorous fertilizers on flower yield , yield components and some quality components of german chamomile, a factorial experiment based on a randomized complete block design with four replications was carried out in the medicinal plant research farm of shirvan college of agriculture during growing season of 2007-2008. nitr...
