in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
the deleterious effects of salinity on plant growth and development are associated with the imbalance ion in plant, decreased k+ and increased na+, and ultimately yield loss. in order to evaluate the effects of salinity, 41 bread wheat varieties (trticum aestivum l.) were planted in the randomized complete block design with three replications under two saline irrigation conditions, 0.631 and 11...
in order to evaluate salinity tolerance in 20 sugar bee genotypes, an experiment was conducted in two fields with salinity (ec= 12 ds/m, ph= 7.6) and non-salinity stress, in the form of rcbd at miandoab agricultural research station. different morphological and physiological traits such as root yield, sugar percentage, white sugar percentage, molasses, n, na, k, syrup purity and green cover per...
the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
this experiment was carried out to investigate the effect of plant density on growth and seed yield of wheat (kodasht cultivar) under saline soils and rainfed condition inanbarolum region of golestan province in 2008-09. an experiment was conducted in three fields with different salinities (6.73, 9.34 and 11.63 ds m-1) based on randomized complete blocks design. treatments were four plant densi...
In order to study the effects of seed inoculation by cycocel and biofertilizers on yield, antioxidant enzymes activity and some biochemical traits of wheat (Triticum aestivum L.) under soil salinity condition, a factorial experiment was conducted based on randomized complete block design with three replications in a research greenhouse of Faculty of Agriculture and Natural Resources, University...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
Salinity is an ever-increasing problem in agriculture worldwide, especially in South Asia (India, Pakistan) and Australia. Improved genotypes that are well adapted to saline conditions are needed to enhance and sustain production in these areas. A screening of 263 accessions of chickpea, including 211 accessions from ICRISAT’s mini-core collection (10% of the core collection and 1% of the entir...
چکیده : * در یک واکنش تک ظرفی و با استفاده از واکنش آلدهید های آروماتیک و 3- متیل 1- فنیل پیرازولین-5- ان با نسبت مولی 1:1، ساختارهای هتروسیکل پیرازول سنتز شد. از مزایای آن، انجام واکنش در دمای اتاق، عدم نیاز به کاتالیزور، بازده بالای واکنش، استفاده از آب بعنوان حلال سبز و بی خطر به جای حلال های آلی وسمی می باشد . * توانستیم با استفاده از ملدرام اسید ومشتقات 2- هیدروکسی بنزآلدهید، ترکی...
To evaluate the effect of soil salinity stress on some vegetative and reproductive traits of sunflower (Helianthus annus L.) oil varieties in Mahabad conditions, a factorial experiment was conducted in greenhouse condition based on randomized complete block design with five replications in 2009. Treatments were included five levels of soil salinity (EC: 0.5 (as control), 2, 4, 6 and 8 ds /m) an...
