association of satellite rna with cucumber mosaic virus (cmv) leads to either attenuation or enhancement of the viral symptoms. for detection of the satellite rnas in iranian isolates of cmv, plant samples showing viral symptoms were collected from different farms in the provinces of east- and west- azerbayjan and ardebil. these samples were inoculated onto the experimental host plants in green...

satellite thermal control ensures safe operating temperature ranges for satellite components throughout the mission life. effects of altitude, spin, and position of satellite radiator(s) on the thermal control of a small low earth orbit (leo) satellite have been studied. results show that change in satellite altitude, in the range considered here, does not produce critical thermal conditions. h...

this paper deals with the investigation of the microstructure and hardness of steel samples cladded with satellite 6-wc composites by using gas tungsten arc welding (gtaw) process. for this purpose, steel samples were coated with unreinforced and reinforced stellite (by 20, 30 and 40 wt.% wc). the cladded samples were evaluated by metallographic studies, microhardness measurement and x-ray diff...

In this paper satellite wave propagation at Ku and Ka band is considered. The design and simulation of a typical satellite beacon receiver at Ka band is designed and simulated for the future works. Also rain attenuation prediction at Ku band using satellite signal beacon measurement and simulations for Iran Telecommunication Research Center (ITRC) are presented. The measurement setup consists o...

The purpose of this study was to investigate the effect of satellite networks (GEM TV and Farsi 1) on the religious beliefs of youth in the city of Farashband. The type of research in terms of purpose, applied and in terms of data collection, was causal-comparative. The statistical population of this study is all the youths of the Farashband city in 2015, which includes 7569 people. The sample ...

Today, leisure time is changing by globalization and using of information technology. Most of people especially women prefer to spend their leisure time by modern technologies. Thus, they spend their leisure time to look up satellite programs and use of the internet. This research has done for sociological consideration of the globalization of communications (internet  & satellite) on leisure t...

the changes in time and location of surface temperature from a water body has an important effect on climate activities, marine biology, sea currents, salinity and other characteristics of the seas and lakes water. traditional measurement of temperature is costly and time consumer due to its dispersion and instability. in recent years the use of satellite technology and remote sensing sciences ...

The present survey study has been carried out to examine the impact of satellite programs on 300 young  people who were permanently watching them. The authors used the theories of some scientists and sociologists like Klapper, Newman, Robertson, Harvey and Gidnez to clarify the variables. The results show that the more satellite programs will be watching, the religious identity is reduced. So, ...
