مقدمه ای بر: تکنولوژی data base و اداره سازمان
در ادراه امور سازمان نیز از تکنولوژی data base در دو زمینه مشخص یعنی بصورت سیستم های عملیاتی و سیستم های اطلاعاتی میتوان استفاده کرد. در شرایط کنونی وجود موانع متعدد از قبیل فرهنگ غالب در سازمان های بزرگ و طرز تلقی مدیران دیوان سالار از یکطرف و تازه گی و پیچیده بودن فنون مربوط به سیتم های data base فقدان دانش، تجربه و تخصص کافی برای بهره گیری کامل از آن از طرف دیگر، برنامه ریزی و اقدام برای ایج...
15 صفحه اولChemical Association via Exact Thermodynamic Formulations
It can be fruitful to view two-component physical systems of attractive monomers, A and B, “chemically” in terms of a reaction A + B ⇀↽ C, where C = AB is an associated pair or complex. We show how to construct free energies in the three-component or chemical picture which, under mass-action equilibration, exactly reproduce any given two-component or “physical” thermodynamics. Order-by-order ma...
متن کاملExact thermodynamic formulation of chemical association
The thermodynamics of interacting systems of two species of particles, A and B, may be specified in ‘‘physical’’ terms using only the two densities ra and rb or, alternatively, in a ‘‘chemical picture’’ using three densities ra , rb , and rc related by a mass-action law corresponding to the ‘‘reaction’’ A1B C, where C denotes a ‘‘compound,’’ ‘‘complex,’’ ‘‘cluster,’’ or ‘‘associated pair.’’ We ...
متن کاملI. General Thermodynamic Treatment of Chemical Equilibrium
Consider an equilibrium reaction aA+ bB ⇀↽ cC+ dD We do not specify any phases, as we will treat the reaction generally using activities. An equilibrium reaction is one that can proceed in both directions, as indicated by the ⇀↽ symbol replacing the usual −→ in the chemical equation. Recall that the molar free energy ∆Ḡj for compound j in the reaction in terms of its activity aj as ∆Ḡ = ∆Ḡ◦ +RT...
متن کاملConsistent Relative Thermodynamic Data for Hydrogen Bonding and Stacking Interactions of Nucleic Acid Base Derivatives
An ab initio method is used in a two state model to calculate consistent relative enthalpies and free energies for the stacking of nucleic acid bases in deoxyribose dinucleotides and the Watson-Crick hydrogen bonding interactions between mononucleotides when uncharged and singly charged. Favorable free energy changes are determined for the formation of dimers between mononucleotides by Watson-C...
