The Iran Water Resources Management Company constructs many dams to control surface water that provide a new potential for aquaculture activities. Trophic status index and natural potential for fish production were investigated in nine small dam reservoirs from northwest of Iran. Prediction of fish productivity was calculated based on phytoplankton biomass (using chlorophyll a concentration in ...

Views and abstraction levels are two major concepts introduced in the software engineering domain in order to enhance the architectural organization of complex systems’ requirements. Despite numerous and substantial works that built and refined those concepts, they still less secure and less standardized to be part of a rough software architecture. This paper begins with a survey of evolution o...

The concepts of free modules, projective modules, injective modules and the likeform an important area in module theory. The notion of free fuzzy modules was introducedby Muganda as an extension of free modules in the fuzzy context. Zahedi and Ameriintroduced the concept of projective and injective L-modules. In this paper we give analternate definition for projective L-modules. We prove that e...

MIS researchers have developed a number of models for studying the software utilization choices of end users. In this paper, we focus on one of these, the Task-Technology fit model. We explore the addition of various personal characteristic constructs, especially Computer Self-Efficacy and Experience.

Two science-learning studies were carried out in the U. S. and Taiwan, to examine whether 4th grade children could benefit from a causally coherent presentation of core concepts explaining molecules and the role that heat energy plays in controlling state of matter. The first study varied the inclusion/exclusion of static versus dynamic graphic presentations that accompanied learning modules. T...
