Emphasis on sustainable agriculture in Iran like the other developing countries, is responsedto the adverse environmental and economic impacts of conventional agriculture. Thisproblem, particularly about “greenhouse production” is considerable. The perceptions ofgreenhouse owners about the environmental, economical and social aspects of sustainableagriculture was discussed in this article. The ...

This paper proposes a two-level model that integrates tense and aspect information, based on theories by both Hornstein (in the spirit of Reichenbach) and Allen, with lexicai-semantic information based on an extended version of $ackendoff's theory that includes a verb classification system proposed by Dowty and Vendler. The model is intended to be extensible to realms outside of the temporal do...

Given a target name, which can be a product aspect or entity, identifying its aspect words and opinion words in a given corpus is a fine-grained task in target-based sentiment analysis (TSA). This task is challenging, especially when we have no labeled data and we want to perform it for any given domain. To address it, we propose a general two-stage approach. Stage one extracts/groups the targe...

The aim of the present study is threefold. The first is that whether there is any difference betweendifferent proficiency level language learners 'use of spatial prepositions. The Second aim is toreveal that if the native language of the participants has any effect on applying the appropriateprepositions and also to find which spatial preposition is difficult to acquire. The present paperexamin...

Aspect Aspect-oriented programming is known as a technique for modularizing crosscutting concerns. However, there are no clear rules to help detect and implement Aspects in the software development lifecycle. Consequently, class developers face changeability, parallel development and comprehensibility problems, because they must be aware of aspects whenever they develop or maintain a class. The...

in this article the author investigates al-ghazzali’s views on the volitional aspect of the soul. al-ghazzali divides the volitional aspect of the human into two levels, human and animal. his use of terms such as practical faculty, practical reason, power and will for human volition raises the important question of whether practical reason has cognitive character and whether it is a stimulus. s...

abstract the proper management of a watershed depends on recognition of effective elements and investigation of their behavior in different conditions. till date, many researches have studied the role of topographical general characteristics on hydrologic behaviors. whereas, the changeability of hydrologic properties under different conditions, especially in iranian watershed has been rarely ta...

For my students I shall consider in detail distributions defined by the principal value and the finite part of divergent integrals. I shall also consider continuity properties of distributions defined by holomorphic functions.
