the first motive for the determination and evaluation of an energy productionsystem is the need to change. such system is dynamic in nature and is influenced bymany factors such as age and physiological status of individual sheep or goat, quantityand quality of available feed and environment including the management systems.traditional pastoral resource assessments do not always account for the...
A pre-nursery system fur raising coconut seedlings was compared with the conventional nursery. The two major refinements introduced in the pre-nursery system are the slicing of seed nuts and transplanting of sprouted seed nuts from pre-nursery beds to nurserv beds, soon after sprouting. The rate of sprouting in the Pre-nursery system was significantly superior. At the end of 20 weeks 76% of the...
It is notable that over the past decade, proven reserves of natural gas have dramatically increased as higher prices and advances in technology have turned previously unrecoverable resources into major sources of domestic production. Moreover, the decline in crude oil reserves has significantly slowed over the past decade. Therefore, there would be an end to the conventional hydrocarbon resourc...
The purpose of this research is to analyze the forging of bevel gears based on conventional forging method with material number 1.7131 with finite element method by means of SUPER FORGE software and to compare it with experimental cold orbital forging results.After doing simulation of conventional forging and obtaining press tonnage due to orbital forging method with DEFORM software, orbital fo...
Using natural gas is known as a clean energy resource and apart from environmental aspect, it is economically and politically of great importance so that countries having conventional and unconventional gas resources have increased investment in novel tech developments especially in unconventional ones. The aim of this study is to analyze the effect of shale gas production on the gas price in t...
Knowledge of medicinal plants and by-products and economic evaluation of their exploitation is one of the basic requirements in order to prepare a vision document for the exploitation of rangeland by-products. In this regard, the present study was conducted with the aim of ecological assessment and estimating the economic indicators of the use of medicinal plants in the montion rangeland of Kho...
in many european states such as spain and italy there has been a significant growth of organic utilizable surface as a consequence of both a change in the model of agricultural production and also in order to satisfy arising demand of organic food. the purpose of this research was to investigate the level of technical, allocative and economic efficiency in italian olive farms with two different...
The growth in demand for electric power and the rapid increase in fuel costs, in whole of theworld need to discover new energy resources for electricity production. Among of the nonconventionalresources, wind and solar energy, is known as the most promising deviceselectricity production in the future. In this thesis, we study follows to long-term generationscheduling of power systems in the pre...
