Let W be a variety of groups defined by a set W of laws and G be a finite p-group in W. The automorphism α of a group G is said to bea marginal automorphism (with respect to W), if for all x ∈ G, x−1α(x) ∈ W∗(G), where W∗(G) is the marginal subgroup of G. Let M,N be two normalsubgroups of G. By AutM(G), we mean the subgroup of Aut(G) consistingof all automorphisms which centralize G/M. AutN(G) ...
هدف از این پروژه مقایسه و بررسی کارایی روشهای عددی مختلف در حل دستگاه معادلات جبری خطی axb می باشد. برای این منظور روشهای مختلف در حل معادلات دوبعدی نویر-استوکس تحت بررسی قرار گرفته است و مساله جریان در حفره ای با سرپوش متحرک ، برای مقایسه روشهای تکراری زیر انتخاب شده است : i)روش تکراری sor ii)روش تکراری adi iii)روش تکراری پیش شرط مزدوج گرادیان بنام orthomin(1) با ماتریس پیش شرط حاصل از تجزیه ن...
background and objectives: nowadays corn flakes are the most common form of breakfast cereals however, their vitamins are declined during the baking process. in this research, production of fortified corn flakes by lactobacillus plantarum and l. reuteri, as well as incorporation of oat and malt fiber as prebiotics have been studied. materials and methods: plackett-burman statistical design was ...
this thesis attempts to study the representations of the third-world intellectuals in three fictional works by the british-educated trinidadian nobel-winner v. s. naipaul: the mimic men, a bend in the river, and magic seeds. the first one recounts the story of ralph singh’s sense of alienation, his experiences as a colonial politician, and his struggle to give order to his disorderly world thro...

we commence by using from a new norm on l1(g) the -algebra of all integrable functions on locally compact group g, to make the c-algebra c(g). consequently, we find its dual b(g), which is a banach algebra so-called fourier-stieltjes algebra, in the set of all continuous functions on g. we consider most of important basic theorems about this algebra. this consideration leads to a rather com...
adaptation of the lord of the rings is considered by many to be among the greatest, most successful and at the same time most popular of the above mentioned trend so far. it is my intention to look at the success and popularity of this epic fantasy in the light of the 9/11 attacks and the war on terror context of g. w. bush’s aura. in so doing i aim at bringing into the light the determining fa...
در پروژه حاضر، [bipy](so3h)2cl2 به عنوان یک واکنشگر جدید و موثر برای تسریع واکنش های آلی سنتز ومعرفی شده است. این واکنشگر به خوبی قادر است واکنش تهیه انواع زانتن ها از جمله آریل-h14-دی بنزو [a,j] زانتن ها، 1،8-دی اکسو-اکتاهیدرو زانتن ها و 12-آریل-8،9،10،12- تتراهیدرو بنزو[a] زانتن -11-اون ها را در غیاب حلال و با بهره های خوب تا عالی تسریع نماید. همچنین [bipy](so3h)2cl2 به عنوان یک کات...
this work aimed to prepare a nanoemulsion preparation containing budesonide and assess its aerodynamic behavior in comparison with suspension of budesonide. in-vitro aerodynamic performance of the corresponding micellar solution (ie. nanoemulsion preparation without oil) was investigated too. nanoemulsions of almond oil containing budesonide, as a hydrophobic model drug molecule, were prepared ...
Ketorolac tromethamine (KT) containing microemulsion-based gels (MBGs) have been formulated, based on the previous phase diagram studies, using a pharmaceutically acceptable surfactant (soybean lecithin; Epikuron 200) and oil (isopropyl myristate; IPM) and the effect of formulation variables on the release profile of the drug from MBGs through intact guinea pig skin and various artificial membr...
