in biaxially strained p-mosfet with si channel, formation of a parasitic parallel channel due to misalignment of energy bands degrades device performance by increasing off-state current. in this paper a new approach has been introduced to eliminate this parasitic channel by increasing the dopant concentration of virtual substrate up to . using simulation the impact of this method on the parasit...

Background: Parasitic contamination of fruits and vegetables is one of the major causes of gastroenteritis in many parts of the world. The aim of this study was to determine the parasitic contamination in fruits and vegetables in the Bauchi area, North-East Nigeria. Methods: From May to July 2017, a total of 776 samples comprising 182 samples of four different types of fruits, and 594 samples ...

background: leishmaniasis is a parasitic disease, that due to the incidence, dissemination and scattering throughout different parts of iran is of paramount importance. this study was carried out with the aim of determining the epidemiology of leishmaniasis cutaneous in khatam during 2008-2012. methods: this is a cross-sectional and retrospective study of collected demographic and epidemiologic...

a simple semi-phenomenological model, which accurately predicts the dependence of thresholdcurrent for temperature of resonant-phonon three well quantum cascade laser based on verticaltransitions is offered. we found that, the longitude optical phonon scattering of thermally excitedelectrons is the most important limiting factor for thermal performance of high frequency thz qcls.in low frequenc...

abstract in order to identify the plant parasitic nematodes of rapeseed fields in north khorasan provice, during years 2007-2008, 50 soil and root samples were collected. nematodes were extracted by centrifugal flotation technique and transferred to glycerin according to the modified de grisse method (1969). the permanent slides were prepared from the extracted nematodes. the nematodes were ide...

The evolution of parasitism is often accompanied by profound changes to the developmental program. However, relatively few studies have directly examined the developmental evolution of parasitic species from free-living ancestors. The lined sea anemone Edwardsiella lineata is a relatively recently evolved parasite for which closely related free-living outgroups are known, including the starlet ...
