to evaluate the effects of fertilizing and deficit irrigation regimes on some chemical properties of soil and plant, an experiment was conducted during 2007 and 2008 growing seasons. experimental design was a split plot based on a randomized complete block design with four replications. the treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (s...
Current conventional agricultural systems using intensive energy have to be revitalized through new integrated approaches relying on renewable energy resources, which can allow farmers to stop dependence on fossil resources. The aim of this study was determining the amount of input–output energy used in onion (Allium cepa L.) production in Khorasan Razavi province. For this purpose, the data wa...
As part of sustainable architecture principles and practices, designers need to define building's architectural requirements based on climatic conditions, environmental preservation and reduction in energy consumption. The natural energy sources such as solar radiation affect thermal and lighting performances of buildings depending on its facade characteristics. Traditionally, buildings thermal...
nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. one of the most important renewable sources is the wind energy. the wind energy is an appropriate alternative source of fossil fuel. the replacem...
background : application of strategic management processes at the local level can lead to modeling and development of efficient systems of energy, wastewater, and environmental protection through air pollution prevention. this process is only possible through attention to the strengths, weaknesses, opportunities, and threats of hospitals. this study was conducted with the aim of the presentatio...
Energy carriers are addressed today as one of the main pillars of energy generation due to the increased growth of industries in developed and developing countries. According to the global view, increased consumption of energy carriers is causing an increase in the production of greenhouse gases, the global average temperature, and this, in turn, results in the quicker melting of ice in Antarct...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
in recent years, the implementation of integrated information systems in the iranian public sector has significantly increased. this is of more importance in holdings and multi-branch organizations. considering the fact that the cost, time-span and quality of implementation of these systems, has a dramatic impact on public sector effectiveness, therefore, identification and classification of fa...
