determination of chlorophyll content and chlorophyll fluorescence has the potential needed to analyze the efficiency of photosynthesis in plants against environmental stresses, especially salinity, and its simplicity facilitates stress evaluation. in order to study the response of different photosynthetic characters to salinity stress at different sugar beet growth stages, two separate experime...
abstract this thesis includes five chapter : the first chapter assign to establish fuzzy mathematics requirement and introduction of liner programming in thesis. the second chapter we introduce a multilevel linear programming problems. the third chapter we proposed interactive fuzzy programming which consists of two phases , the study termination conditions of algorithm we show a satisfac...
The rate at which tomato fruits ripe was investigated via the biosynthesis of lycopene in two tomato varieties under the conditions of field and ambient temperature ripening. Results showed that the biosynthesis of lycopene follows a first-order kinetics in both varieties with calculated rate constants of 1.2×10-2 and 1.4×10-2 d-1 for Ibadan local and Roma types respectively under the field rip...
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
Abstract Terminal drought stress is one of the most important environmental stresses affecting plant morphology and physiology and has major effects on agricultural production. The purpose of this experiment was to investigate the effect of water deficit stress on changes in physiological traits of wheat in a randomized complete block design with three replications in two cultivation years of ...
drought stress is one of the most important abiotic stresses which can affect the growth of a plant, thereby curbing crop yield. identification of effective morphological traits is the main aim of each breeding program. our objective was to identify agronomic traits associated with changes in grain yield of wheat under irrigated and drought conditions. to address this objective, grain yield and...
آسم یک بیماری مزمن است که در آن راههای هوایی باریک و ملتهب می شود، که این در نتیجه افزایش ترشح موکوس در راههای هوایی است به موجب این، تنفس سخت تر و کوتاهتر صورت گرفته و فرد دچار تنگی و خس خس سینه می گردد. هدف از اجرای این تحقیق،بررسی اثر یک دوره تمرینات ورزشی هوازی و مصرف مکمل ویتامین d(1000 واحد) بر برخی از شاخص های تنفسی بیماران آسم بود. روش تحقیق :نمونه های تحقیق 32 بیمار آسمی (3 گروه تجربی...
