Background: Phytate is an anti-nutritional factor in plants, which catches the most phosphorus contents and some vital minerals. Therefore, Phytase is added mainly as an additive to the monogastric animals’ foods to hydrolyze phytate and increase absorption of phosphorus. Objectives: Y. intermedia phytase is a new phytase with special characteristics such as high specific activity, pH stabilit...
Let g be a fixed element of a finite group G. We introduce the g-noncommuting graph of G whose vertex set is whole elements of the group G and two vertices x,y are adjacent whenever [x,y] g and [y,x] g. We denote this graph by . In this paper, we present some graph theoretical properties of g-noncommuting graph. Specially, we investigate about its planarity and regularity, its clique number a...
Let $G$ be a non-abelian group and let $Gamma(G)$ be the non-commuting graph of $G$. In this paper we define an equivalence relation $sim$ on the set of $V(Gamma(G))=Gsetminus Z(G)$ by taking $xsim y$ if and only if $N(x)=N(y)$, where $ N(x)={uin G | x textrm{ and } u textrm{ are adjacent in }Gamma(G)}$ is the open neighborhood of $x$ in $Gamma(G)$. We introduce a new graph determined ...
در بخش اول این پایان نامه، تبدیل متقابل ایزومرهای اتصال نیترو و نیتریتو برخی از کمپلکس های پنتاآمین و تتراآمین کبالت(iii) در حالت جامد با روش گرماسنجی پیمایشی تفاضلی (dsc) بررسی شده است. کمپلکس های این تحقیق به شرح ذیل می باشند: [co(nh3)5y]x2 )y=no2 and ono, x=cl?, br?, i?, pf6? ؛(1) (cis-[co(nh3)4y2]x )y=no2 and ono, x=cl?, no3?, clo4؛(2) ( trans-[co(en)2y2]x )en=ethylenediamine, y=no2 and on...
Dipolar-dephasing method provides some information about the strength of dipolar coupling in solids. Dipolar dephasing technique measures the time for a polarized carbon nucleus to lose its magnetization once the proton locking field is terminated. The dynamics of guest molecules adsorbed within the cavities and channels of nonporouszeolite strongly depend on the structure and chemical composit...
Introduction Natural and artificial radionuclides are the main sources of human radiation exposure, which enter the food chain from the environment. Radionuclides can affect human health by transferring from soil to plants and entering the human body. In this research study, we aimed to determine the activity concentrations of radionuclides and calculate the average annual committed effective d...
conclusions albumin gradient method is the enrichment of y-bearing chromosome sperms. separation of spermatozoa by albumin gradient method, introduced by ericsson, is a suitable method for sex selection of male offspring. this technique is safe, because it neither requires toxic materials during sperm separation, nor involves embryo manipulation. objectives the study aimed to assess the separat...
The purpose of this research was to determine the relation between principals' transactional and transformational leadership styles and the motivational needs of physical education teachers based on Douglas McGregor's X & Y theory. According to X theorical supposing human is interest to work and responsible and this is in her essence. This person is self control and self motivation. Whereas in ...
در این پایان نامه، پایداری هایرز - اولام - راسیاس معادله تابعی مکعبی f(mx + y) + f(mx -y) = mf(x+y) + mf(x-y) + m f(x-y) + 2(m3-m)f(x) را جاییکه m?1 عدد صح?ح مثبت است را بدست می آور?م همچنین با استفاده از روش نقطه ثابت پایداری هایرز - اولام - راسیاس را برای معادله تابعی f(2x+y) = 2f(x) + f(y) + f(x+y) - f(x-y) در فضای باناخ اثبات خواهیم کرد
Zeolites A, X and HS were synthesized from natural Iranian Kaolinite by alkaline fusion,,followed by refluxing the mixture. The transformation of zeolites X to HS and Y to P were studied at different time intervals by X-ray diffraction and Scanning Electron Microscopy (SEM). It was revealed that in solution, zeolites HS and P are more stable than zeolites X and Y respectively
