growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
longitudinal heat conduction is an important parameter in the cryogenic field, especially in cryogenic heat exchangers. in the present work, the parasitic effect of tube wall longitudinal heat conduction on temperature measurement has been studied in cryogenic laminar hydrogen flow. the effects of various parameters such as wall cold end temperature, wall thermal conductivity, gas volumetric fl...
We measured enteric parasitic infection prevalence and the effect of treatment on human immunodeficiency virus (HIV) RNA levels to assess their importance to HIV primary care in resource-limited settings. Adults in Lilongwe, Malawi, were evaluated, treated, and followed-up for parasitic and HIV infections. Of 389 patients, 266 (68%) were HIV infected. Helminth infections were more common in HIV...
Introdution: Chemical drugs against parasites are beneficial, but this method has some problems such as drug resistance, residue and unwanted side effects associated. Therefore, study on alternative therapies especially herbal compounds are research priorities. According to antimicrobial and anti-parasitic effects of Artemisia spp. extracts, this work aimed to study the effect of Artemisia spec...
the risk of disease spread through water, fruits and vegetables contaminated through unclean waters varies from region to another. springs and underground water resources are essentially free of germs or they have tolerable levels of germs; unless they are infected by surface water or human excreta. scientific reports have shown that outbreaks of food-borne illnesses especially foods such as fr...
results overall, 161 children at a mean age of 9.25 ± 3.37 years (age range = 1 - 15 years old) hospitalized with a definite diagnosis of the hydatid cyst between 2001 and 2014 were studied. the male-to-female ratio was 1.6:1. the most commonly involved organ was the lung (67.1%), followed by the liver (44.1%) and a combined liver and lung involvement was found in 15.5% of the patients. the cys...
In this paper, hybrid modeling of Micro-strip antenna is presented. Broadband frequency of operation demonstrated by single geometry .for broadening the bandwidth and maximum directional gain (6.6dBi 8dBi) gap-coupled multi-resonator loaded on parasitic and active patch. The geometry of a single probe fed rectangular Micro-strip antenna incorporating a slot and gap coupled with parasitic and ac...
