 We have developed a theoretical cross-layer model that allows assessing the goodput and delay of the IEEE 802.11a local area networks (WLANs) operating simultaneously under the distributed coordination function (DCF) basic access (BA) and request-to-send/clear-to-send (RTS/CTS) medium access control (MAC) protocols under saturated traffic over correlated and uncorrelated fading channels. Resu...

the objective of this study was to determine the effect of calcium borogluconate injection 24, 48 hours prepartum and immediately postpartum on dry matter intake at day of calving, milk yield, and as well on blood metabolites during the first 21 days of postpartum in cows fed anionic diets. thirty six lactating dairy cows were arrenged by parity (1, 2, 3+) and allocated to three subcutaneous in...

Background and Aims: The rate of urinary tract infection caused by the extended-spectrum-β-lactamase- (ESBL) producing Escherichia coli (E. coli) is increasing worldwide. This study aimed to assess the frequency of blaCTX-M genes in the E. coli isolated from urinary tract infection (UTI) in outpatients. Methods: 240 E. coli bacteria were isolated from the outpatients’ urine samples in the Kerma...

Peripheral neuropathy is a common side effect of chemo therapy with paclitaxel. Among patients experiencing pac litaxel-induced peripheral neuropathy, L-glutamine (10 g orally three time daily for four days starting 24 hours after completion of therapy with paclitaxel) produced significant reductions in the severity of dysesthesias and numbness (P < 0.05). Significant reductions were also obser...

abstract background: premenstrual syndrome (pms) can cause problems in daily work and relationships. materials and methods: eighty‑six women were randomly assigned to two intervention groups and one control group. patients were asked to fill out the pms daily symptoms record for 2 months, and then the participants were randomly assigned to one of the three study groups. medical intervention was...

background: existence of bacterial host cell dna contamination in biopharmaceutical products is a potential risk factor for patients receiving these drugs. hence, the quantity of contamination must be controlled under the regulatory standards. although different methods such as hybridization assays have been employed to determine dna impurities, these methods are labor, intensive and rather exp...
