STUDY ON SIMPLE ANALYSIS FOR WARM WATER DIFFUSION

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

Simple Equations for Predicting Entropy of Ammonia-Water Mixture

This work presents a set of three simple and explicit equations as a function of temperature, pressure, and mass fraction for calculation of the entropy of the ammonia-water mixture in saturated and super heated conditions. They are intended for use in the optimization and second law efficiency of absorption processes. The equations are constructed by the least square method for curve fitting u...

A Simple Method of Water Analysis

MCE modeling in zoning areas with warm water and cold water aquaculture capability by IDRISI (case study: Golestan province)

This study aimed to fulfill demands of information on aquaculture capability and to estimate ecological potential in Golestan Province. Aquaculture site selection (warm and cold water fishes) was conducted by MCE[1] method using GIS. The aquaculture suitability maps were produced by multi-criteria evaluation model (MCE), Fuzzy and Analytic Hierarchy Process (AHP) in ArcGIS 9.3. The most appropr...

developing a pattern based on speech acts and language functions for developing materials for the course “ the study of islamic texts translation”

هدف پژوهش حاضر ارائه ی الگویی بر اساس کنش گفتار و کارکرد زبان برای تدوین مطالب درس "بررسی آثار ترجمه شده ی اسلامی" می باشد. در الگوی جدید، جهت تدوین مطالب بهتر و جذاب تر، بر خلاف کتاب-های موجود، از مدل های سطوح گفتارِ آستین (1962)، گروه بندی عملکردهای گفتارِ سرل (1976) و کارکرد زبانیِ هالیدی (1978) بهره جسته شده است. برای این منظور، 57 آیه ی شریفه، به صورت تصادفی از بخش-های مختلف قرآن انتخاب گردید...
