Advanced drilling technology makes it possible to penetrate oil and gas sites with deep bedding of reservoir, a complex multi-layer structure high reservoir temperature at the well bottom, reaching 150°C. The difficult geology strata leads fact that productive layers are flooded unevenly. In this work causes for water cut in reservoirs given, repair insulation technologies isolation water-beari...

abstract- maize production, which is ranked after wheat and barely in fars province, iran, needs a considerable amount of irrigation water that is not available in scarce water conditions in drought situations. therefore, proper planting method can improve irrigation water management. the objectives of the present study were to investigate the effects of two planting methods, on-bed and in furr...

participatory conservation, as bottom-up management, is currently the most acceptable modelfor management of protected areas across the world. social context is a central issue in the sustainablemanagement of conservation areas. it is also crucial to introducing participatory conservation. the newapproach therefore recognizes rural communities as key partners in biodiversity management and seek...

use of nano-materials has increased in various aspects of human life. however, possible outbreak of nano-materials toxicity in humans and other organisms is one of the future challenges. different chemical precursors which are used in chemical approaches for production of nano-materials may have secondary and sometimes toxic effects in living organisms. these secondary effects may be reduced in...

a one-way moldboard plow turns over soil in only one direction. problems created by this type of tillage in iran include compaction of boundary regions, decreased efficiency of irrigation and disruption of bed leveling, requiring the use of bed-leveling equipment every few years. to overcome these problems, the use of a two-way plow with two harrows which turns over the soil to both the left an...

In this paper, we endorse and advance an emerging bottomup approach to game studies that utilizes techniques from natural language processing. Our contribution is threefold: we present the first complete review of the growing body of work through which this methodology has been innovated; we present a latent semantic analysis model that constitutes the first application of this fundamental bott...

Online social platforms, e-commerce sites and technical fora support the unfolding of informal exchanges, e.g. debates or discussions, that may be topic-driven or serendipitous. We outline a methodology for analysing these exchanges in computational argumentation terms, thus allowing a formal assessment of the dialectical validity of the positions debated in or emerging from the exchanges. Our ...
