this article proposes an optimization model for preventing the waste of time in the educational and research activities' cycle of an organization such as a university. for this purpose and in order to increase efficiency and prevent the waste of time; the graph theory models have been used. the educational and research activities diagrams of a supposed university is drawn by the use of graphs t...
Background: Food waste is a very serious problem, it is proven that Indonesia is the second largest producer of food waste in the world. A limited waste management system will result in a decrease in environmental quality such as air pollution, water pollution, and soil pollution. So far, the waste management system is only limited to reducing waste generation. Life Cycle Assessment (LCA) is a ...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
Introduction:Among the pollutants in waste gases, volatile organic carbons (VOCs) are very harmful for human, animals and plants. Formaldehyde is a member of VOCs family and is very toxic, mutagen and carcinogen. For removing formaldehyde, Some biological methods for treating waste gases such as bio-trickling filter reactor (BTFR) have been developed by scientists. The aim of this study was to ...
OBJECTIVE AND RATIONALE The purpose of this study is to evaluate the degree of fibroid shrinkage which well correlates with symptom regression, and thus to assess the effectiveness of the procedure. METHOD 31 patients were included in the trial after selection. All the patients were thoroughly evaluated before embolization, the following day and at a month after but also at 3 months for 10 of...
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
aims: several methods have been used for textile wastewater treatment. the aim of this study was to evaluate the efficiency of rosa damascena watering waste ash for cod and color removal from textile wastewater. materials & methods: rose watering waste was gathered from one of the kashan processing plants. the raw wastewater sample was taken from one of the textile industries in kashan country...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
