The concepts of Virtual Reality (VR) and Virtual Environments (VE) have been introduced as powerful methods for presenting complex three-dimensional scenes. The widely used VR-displays like Workbenches (large-scale horizontal projection plane) and CAVEsTM (secluded room of projection planes) differ mainly from conventional monitors by allowing a stereoscopic visualisation of three-dimensional s...
Research on the relationship between work group diversity and performance has yielded inconsistent results. To address this problem, the authors propose the categorization-elaboration model (CEM), which reconceptualizes and integrates information/decision making and social categorization perspectives on work-group diversity and performance. The CEM incorporates mediator and moderator variables ...
We analyse the properties of unresolved multiple stars within the full-sky list of radial velocity standard stars, and we estimate that a low remaining fraction would have a radial velocity variation during the mission larger than the requirement. The need for supplementary observations to specifically remove these multiple stars does not appear justified. CU6 The non-single star content of the...
the present study was an attempt to determine the types of motivation and levels of foreign language learning anxiety among efl students studying at azad and state universities in kermanshah and to determine the relationship between these two factors and language proficiency and gender. to this end, the foreign language learning motivation scale, by deci and ryan )1985(, were administered to 12...
The aim of this research was to determine the effects of Camphorosma monspeliaca species on soil variables in its habitat. Ecological positive or negative effects of new species on environment must carefully be examined before allowing their plantation in vast areas on the other hand these species with their special characteristics have special effects on their surrounding environment that sho...
Performance of proper deep tillage can reduce negative effects of soil compaction. The objectives of the research were to determine the effects of deep tillage application on soil physical properties and wheat yield. Therefore, in 2006-2007 an experiment was conducted at Tajarak Agricultural Research Station of Hamedan on a soil with clay loam texture. In this research, four tillage methods wer...
abstract the present research is prepared to study the culture of tea consuming among iranian. the case group which was statistically used for this study was people of lahijan , about four hundred wich were chosen according to their age , gender , education and occupation , randomly selected to fill the questionnaire . then the data collected through the questionnaire was analyzed according ...
results the simulation results showed that the penetration depth and temperature rise of 980 nm wavelengths were different from those of 1064 nm wavelength. it appeared that 1064 nm wavelength penetrated to deeper layers of tissue compared with 980 nm. moreover, temperature rise during 1064 nm irradiation led to temperature increase in allowable ranges. the findings proved the reason why 1064 n...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
