MCM-41 mesoporous silica is synthesized based on a self assembly method, using a quaternary ammonium template, CTAB for the adsorption of sulfur compounds from model oil (1.0 mmol/l DBT in dodecane solution). Then the adsorption capability of MCM-41 assembled on the surface of bacterium Rhodococcus erythropolis IGTS8 is examined regarding the improvement of the biodesulfurization process of...
an artificial neural network (ann) approach was used to model the wheat production. from an extensive data collection involving 40 farms in canterbury, new zealand, the average wheat production was estimated at 9.9 t ha-1. the final ann model developed was capable of predicting wheat production under different conditions and farming systems using direct and indirect technical factors. after exa...
In power grids, there must always be a balance between energy production and consumption. Due to the variable nature of consumers, energy production should also be subject to these changes. Electricity storage is one of the most important issues in the electricity industry, which can generate many ancillary services such as load curve leveling, peak shaving, integration with renewable units, ro...
Energy, as one of the most important production factors and also one of the most essential final products, has a special place in the economic growth and development of countries. Financial development is also known as one of the factors affecting economic growth, which can affect energy consumption in different ways. In this research, using composite data and the PVAR (vector autoregression) m...
The ever raising request for energy and resource limitations in the world, particularly Iran, have ever increasing attention to intense research in optimization, and economization of energy consumption. Since, the application of traditional methods for production of sugar especially in Iran is associated with high consumption of energy and water, using of pulsed electric field (PEF) technology ...

Nowadays, estimating the ampere consumption and achieve to the optimum condition from the perspective of energy consumption is one of the most important steps to reduce the production costs. In this research it is tried to develop an accurate model for estimating the ampere consumption by using the artificial neural networks (ANN).In the first step, experimental studies were carried out on 7 ca...
Background & objectives: One of the biggest concerns about the increasing development of the mining industries, especially in the dry and tropical regions, is their high water consumption and, consequently, the serious threat to the local water resources as well as the impacts of these industrieschr('39') pollution on the environment and other downstream water resources. Therefore, it is necess...
In recent years, optimal use of fossil fuels, reduction of environmental pollution and exploitation of renewable energy is one of the most important issues in the policies of different countries, and as you know, Iranchr('39')s electricity industry is dependent on fossil fuel consumption strongly, which causes environmental pollution. The aim of this study is to obtain the optimal combination o...
