background: organ transplant recipients can experience serious diseases from infections due to emerging and reemerging parasitic infections. this study was carried out to evaluate the prevalence of intestinal parasites among renal transplant re-cipients of iran. methods: this cross-sectional study was conducted from june 2003 to august 2004 on renal transplant recipients in iran. a total of 706...

sunflower (helinathus annuus) is a susceptible host to the holoparasite hemp broomrape (orobanche ramosa) in central parts of iran, causing yield loss due to severe infestations. a field study was conducted in 2006 to evaluate the efficacy of glyphosate for controlling the parasitic weed hemp broomrape in sunflower. glyphosate was applied once or twice at five rates ranging from 0.075 to 0.450 ...

in this study parasitic infection of bobwhite and japanese quails were clarified in farms of garmsar city in province of semnan. forty quails from two breeds randomly were selected and they examined to identify all internal and external parasites .finding was shown that five percent of the quails examined harbored one or more species of helminthes. two cestodes, raillietina echinobothrida and r...

The bulk MOSFET scaling has recently encountered significant limitations, mainly related to the gate oxide (SiO2) leakage currents (Gusev et al., 2006; Taur et al., 1997), the large increase of parasitic short channel effects and the dramatic mobility reduction (Fischetti & Laux, 2001) due to highly doped Silicon substrates precisely used to reduce these short channel effects. Technological sol...

Praziquantel (PZQ) is effectively the only drug currently available for treatment and control of schistosomiasis, a disease affecting hundreds of millions of people worldwide. Many anthelmintics, likely including PZQ, target ion channels, membrane protein complexes essential for normal functioning of the neuromusculature and other tissues. Despite this fact, only a few classes of parasitic helm...

This article presents an automatic digital unbalanced impedance bridge for comparing two-port impedances: R-R, R-C and C-C. The consists of a two-channel source voltage sinusoidal waveforms supplying the arms three-channel precise digitizer, by means which complex ratio output voltages relative are determined. hardware implementation is based on relatively inexpensive universal data acquisition...

Existing research on human channel modeling of galvanic coupling intra-body communication (IBC) is primarily focused on the human body itself. Although galvanic coupling IBC is less disturbed by external influences during signal transmission, there are inevitable factors in real measurement scenarios such as the parasitic impedance of electrodes, impedance matching of the transceiver, etc. whic...

multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...
