background: the rapid growth of computer games, has taken a major part of teenagers leisure time. the improper and overuse of these games, can be considered as physical, mental and social threats. the goal of this study was to determine the relationship between playing computer games and students’ aggression and academic progress.   methods: in this cross- sectional study, 292 students in grade...

Computer supported cooperative work (CSCW) environments enable users to interact with each other by using computers to conveniently share relevant data across the user interface. Awareness is an essential requirement in CSCW to convey precise information about the context in which the work in group is taking place, contributing thus to collaboration between users. In this kind of environments, ...

The purpose of this paper is three fold. First, the major theoretical pattern relationships of TV and/or FM transmitting antennas are dealt with. Secend, the computer calculation method and designing of such patterns using the given relationships. And third, a method in which a computer graphic system can be used to design such antennas for a specific pattern is introduced and its results are p...

In search a hydrogen source, we synthesized TiO2-Cu-graphene composite photocatalyst for evolution. The catalyst is new and unique material as it consists of copper-decorated TiO2 particles covered tightly in graphene obtained fluidized bed reactor. Both, reduction copper from Cu(CH3COO) at the surface covering TiO2-Cu thin layer by Chemical Vapour Deposition (CVD) were performed subsequently f...

Thanks to the ever-developing educational technologies, more and institutions testing organizations around world have been delivering their events through computer-based formats. As far as language assessment is concerned, these developments led questions on all sorts of validity being raised by researchers, especially regarding speaking skill. This exploratory paper compares contrasts pros con...
