Graphene field-effect transistors exhibit negligible transconductance under two scenarios: for any gate-to-source voltage when the drain-to-source is set to zero, and an arbitrary provided that equals Dirac voltage. Hence, extracting channel parasitic series resistances from S-parameters these conditions enables analyzing their dependence on gate drain biases. This fundamental assess portion of...

parasitic colitis, especially entamoeba histolytica, is a well-known disorder in the middle east particularly in iran. the carrier state of the disease or the chronic type frequently remains undiagnosed or mistaken as irritable bowel syndrome which results in further discomfort and increases the incidence of associated complain. we devised a technique by inserting bisacodyl suppository and then...

as a part of a major ecological study of hanna wetland, semirum region, isfahan province, parasitic infestation of 3 native and one introduced fish species were investigated. a total of 120 fish specimens were collected by both cast net and a series of gillnets between fall and winter 2007, and spring and summer 2008. some of the observed parasites are reported for the first time as new host re...

results bulinus truncatus was detected in seven locations. in addition, melanoides tuberculata, which is also considered medically important, and physa acuta were detected. the prevalence of bulinus truncatus, melanoides tuberculata, and physa acuta was 6%, 5.5%, and 88.5%, respectively. background bulinus truncatus is the intermediate host of schistosoma haematobium, which is a causative agent...

Cutaneous larva migrans is skin eruption caused by infestation and migration of animal hookworm larvae in the human skin. It is common in tropics and sub‒tropics.1‒3 CLM has become common among travellers. The disease mainly occurs in resource‒poor communities.1 CLM presents as typical erythematous, serpiginous, pruritic, migratory skin eruptions. Lesions usually depends on area in contact with...
