the second somatosensory area (sli) has been studied both by electrical evoked potentials24 and magnetoencephalography (meg)5 magnetic evoked fields of contralateral primary somatosensory and ipsilateral second somatosensory cortices of 12 normal subjects were recorded in response to median nerve electrical stimulation by means of a single magnetometer. we detected. in addition to the usual con...

background lesions in perineal area are common. the usual treatment is coverage by skin graft and flaps which may be local, pedicled or free types. in this paper v-y flaps were used to cover the defects. methods v-y flaps were used in the gluteal area in 15 patients. lesions were due to different causes. results of 15 patients, 11 were males and 4 were females. their ages ranged from 3 weeks to...

a sequence of permian rocks crops out in northwest of khur in central alborz, north of iran. this sequence consists of the dorud (asselian-sakmarian), ruteh (artinskian-murgabian) and nesen (early djulfian) formations. the ruteh and nesen formations in alborz range were deposited in a shallow marine environment of the continental margin in the paleo-tethys. the ruteh formation with a thickness ...

abstract the propose of this study was evaluation of cropsyst model on growth simulation and yield stimation of canola under different irrigation treatments. canola (talaye) was sown under 5 treatment and 4 replicants in completed randomized block designs at the college of agriculture, shiraz universityduring 2007-2008. during the growth season dry mass and lai was meseaured frequently, then mo...

the permian deposits in the stratigraphic section of sangsar (located in the eastern alborz), are the best expose in the semnan area. this sequence consists of the doroud (asselian-sakmarian), ruteh (artinskian-murgabian) and nessen (early djulfian) formations. the dorud formation in the studied section with 56 m thickness consists of conglomerate, sandstone and quartzite, which is disconformit...

When planning a wireless local area network, there are design issues that need to be considered. In this paper, the fundamentals of planning a wireless local area network are introduced and discussed to highlight the requirements involved. Network constraints, as encountered in the physical environment, are discussed and their relevance to wireless network design is investigated. The paper conc...

Wireless Local Area Networks (WLANs) are subjected to interference because of their working in Unlicensed Spectrum. Coverage ranges of WLANs are 30 to 300m. Channel Assignment is one of the most important problems in the WLANs. In this paper we present a Survey on the Channel Assignment techniques in IEEE 802.11.After analyzing different methods a qualitative comparison has been carried out for...
