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,...
The proposal of this paper is to provide a simple angular random walk model to build up polypeptide structures, which encompass properties of dihedral angles of folded proteins. From this model, structures will be built with lengths ranging from 125 up to 400 amino acids for the different fractions of secondary structure motifs, which dihedral angles were randomly chosen according to narrow Gau...
Background and Objective: Acute lymphoblastic leukemia is a disorder caused by the proliferation of malignant immature lymphoid cells. GRAF (GTPase regulator associated with focal adhesion kinase) which acts as a tumor suppressor gene is disabled in hematologic malignancies due to genetic and epigenetic abnormalities. In this study, GRAF gene expression was inspected in patients with B-ALL. ...
در این پایان نامه ما دو مفهوم فضاهای داگلاس و فضاهای لندزبرگ که حالت کلی از فضاهای بروالد است، را مورد مطالعه قرار می دهیم. سپس شرایطی را که فضای فینسلر مسلح به یک و یا چند (α , β)- متریک باشند، را با داشتن انحنای بروالد ضعیف مورد بررسی قرار می دهیم.
background: we aimed to determine the incidence of co-inheritance as well as interaction of sickle cell trait (sct) and α thal /β thal mutations in south and south central of iran. method: we employed a pcr and restriction fragment length polymorphism techniques to confirm diagnosis of sickle cell trait. all subjects were screened for any α/β -thalassemia mutations using a gap-polymerase chain ...
Abstract The coupled fractional Fourier transform $\mathcal {F}_{\alpha ,\beta}$ Fα,β is a two-dimensional depending on two angles α and β , which are in such way that the parameters $\gamma =(\alpha +\beta )/2$ xmlns:m...
In this research the α and β phases of hemihydrate have been prepared from Alamout natural gypsum and their setting times have been measured. The IR spectroscopy has been used for characterization of α and β phases of hemihydrate from gypsum. The α and β phases of hemihydrate distinguished from each other by X-ray powder diffraction (XRD). The setting times of pure α and β phases and mixtures o...
A method for clean determination of the unitarity angles α and γ is proposed that uses only direct CP violation and does not require any time dependent measurements. The method takes advantage of helicity amplitudes for Bu, Bd and Bs decay to two vector mesons and can be used, at any B-facility, in conjunction with a large number of modes. It also allows for experimental tests of theoretical ap...
We consider a stochastic process with long-range dependence perturbed by multiplicative noise. The marginal distributions of both the original and noise have regularly-varying tails, tail indices α,α′>0, respectively. is taken as Karlin model, recently investigated model that has characterized memory parameter β∈(0,1). establish limit theorems for extremes reveal phase transition. In terms ther...
The role of the rigidity of a peptide chain in its equilibrium dynamics is investigated within the framework of a microscopic model. The stacking interaction characterizing the chain rigidity is found to be repulsive for both types of protein secondary structure (α-helix and anti-parallel β-sheet) mainly encountered in natural proteins. A discrete breather (DB) or else intrinsic localized oscil...
