study of dna interaction with ethylenediaminetetraacetic acid and sesamol food additives
برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
15 صفحه اولContact problems involving a cooled punch
Certain problems in which a cooled rigid punch indents an elastic half-space have no steady state solution. A simple model is described in which it is shown that this paradox is avoided by the assumption of a thermal resistance varying inversely with contact pressure. A limiting case of this system retains linearity and introduces a state of "imperfect" contact in which contact pressure is negl...
متن کاملOn the Linear Combinations of Slanted Half-Plane Harmonic Mappings
In this paper, the sufficient conditions for the linear combinations of slanted half-plane harmonic mappings to be univalent and convex in the direction of $(-gamma) $ are studied. Our result improves some recent works. Furthermore, a illustrative example and imagine domains of the linear combinations satisfying the desired conditions are enumerated.
متن کاملPlane Strain Deformation of a Poroelastic Half-Space Lying Over Another Poroelastic Half-Space
The plane strain deformation of an isotropic, homogeneous, poroelastic medium caused by an inclined line-load is studied using the Biot linearized theory for fluid saturated porous materials. The analytical expressions for the displacements and stresses in the medium are obtained by applying suitable boundary conditions. The solutions are obtained analytically for the limiting case of undrained...
متن کاملThe Effect of Heat Flow on the Contact Area between a Continuous Rigid Punch and a Frictionless Elastic Half-space
A general proof is given of the theorem that, if a continuous rigid punch indenting an elastichalf space is heated, the separation of the solids will increase and part of the contact area will belost. It is also shown that if the punch is convex, the contact area cannot be multiply-connected. R~um~On donne une preuve g6n6rale du th6or6me que, si un poinqon continu rigid, p6n6tra...
