introduction: this study was designed to evaluate the effects of treatment with flaxseed oil (fso) on renal ischemia-reperfusion (rir) injuries in rats. materials and methods: in this study, 32 wistar rats were randomly studied in four groups: co+ns (control group with normal saline administration), sh+ns (sham group with normal saline administration), rir+ns and rir+fso. fso (0.2 ml) was admin...

Today Free-Space Optical communication (FSO)has overcome the radio frequency communication. This paper gives an overview of the availability of an FSO system and its different weather conditions. It describes problems that the designer faces while implementing an FSO system and to overcome that problems .Performance analysis of a system for different weather conditions is carried out. Calculati...

This letter presents a unified analytical framework for the computation of the ergodic capacity and the outage probability of relay-assisted mixed FSO/RF transmission. In addition to accounting for different FSO detection techniques, the mathematical model offers a twofold unification of mixed FSO/RF systems by considering mixed Málaga-M/κ-μ shadowed fading, which includes as special cases near...

The forms of cytochrome P450 involved in the stereoselective S-oxidation of flosequinan [(+/-)-7-fluoro-1-methyl-3-methylsulfinyl-4-quinolone] were investigated in vitro using liver microsomes from rats and humans. Rat liver microsomes supplemented with NADPH catalyzed the four different S-oxidations, which were from flosequinan sulfide (FS; 7-fluoro-1-methyl-3-methylthio-4-quinolone) to R(+)- ...

Free space optics (FSO) uses air as a transmission medium and is significantly affected by the various weather conditions such as haze, rain, fog, snow, wind, etc. In this paper, the behaviour of 16 × 2.5Gb/s FSO system under the effect of the most critical weather conditions using RZ format has been investigated. The operating channel frequencies range from 193.4THz to 189.7THz with the freque...

In recent years, free space optical (FSO) communication has gained significant importance owing to its unique features: large bandwidth, license free spectrum, high data rate, easy and quick deployability, less power and low mass requirement. FSO communication uses optical carrier in the near infrared (IR) and visible band to establish either terrestrial links within the Earth’s atmosphere or i...

Free-space optical (FSO) communication is a cost effective and high data rate access technique, which has been proving itself a best alternative to radio frequency technology. FSO link provides high bandwidth solution to the last mile access bottleneck. However, for terrestrial communication systems, the performance of these links is severely degraded from atmospheric loss mainly due to fog, ra...
