we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
During the homogeneous-heterogeneous autocatalytic chemical reaction in the dynamics of micropolar fluid, relaxation of heat transfer is inevitable; hence Cattaneo-Christov heat flux model is investigated in this report. In this study, radiative heat flux through an optically thick medium is treated as nonlinear due to the fact that thermal radiation at low heat energy is distinctly different f...
the heat and mass transfer analysis for mhd casson fluid boundary layer flow over a permeable stretching sheet through a porous medium is carried out. the effect of non-uniform heat generation/absorption and chemical reaction are considered in heat and mass transport equations correspondingly. the heat transfer analysis has been carried out for two different heating processes namely; the prescr...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...

a mixture of sodium lauryl sulfate (sls) as ionic emulsifer and stearyl alcohol as non-ionic emulsifer was employed in a vinyl chloride emulsion polymerization reaction to study the infuence of various interactive parameters involved in the reaction system. it was found that the particle size was dependent on the amount and type of emulsifer. the average particle size of polyv...
a specific polymerase chain reaction (pcr) method was applied for identification of bovine (bos taurus), ovine (ovis aries) and caprine (capra hircus) pure and binary mixtures of raw and heat-processed meats. these meats are used in food industry products and/or for direct consumption of consumers. the mitochondrial dna was amplified as a template in a pcr reaction by use of specific primers re...
a micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. governing equations were solved base on the finite volume method with fluent software. in upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. two sections were separated with solid part which played as heat exchanger and trans...
تلاش این مجموعه بررسی تکنیک هایی است که به منظور یافتن مقادیر بهینه ی ضرایب نرخ واکنش برای یک مکانیزم واکنش داده شده مورد استفاده قرار می گیرند. هر چند روش های گرادیانی به خوبی مورد استفاده قرار می گیرند اما این مجموعه بر روی الگوریتم های تکاملی هوشنمند که در سالهای اخیر به وجود آمده اند و عملکرد بهتری نسبت به روش های کلاسیک دارند تمرکز می کند. بر خلاف روش های سنتی با پایه ی گرادیانی، یکی از مه...
reaction to fire of fire-retarded rigid pur foams and two types of metal faced rigid polyurethane foam core sandwich panel was evaluated by using cone calorimeter test method. the tests were carried out in various radiative heat fluxes from 15 to 75 kw/m2. the radiation rate effect on reaction to fire parameters, including time to ignition (tti), peak of heat release rate (prhr), total heat rel...
