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 ...

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 ...

BACKGROUND Understanding the etiology of appendicitis is important for developing effective treatments the relationship between parasitic appendicitis and various socio-cultural factors were examined, particularly with respect to the incidence of literacy. The aim of the article was to research the relations between parasitic appendicitis and literacy ratio in population. METHODS Cases of par...

Power module design is needed for high system performance and reliability, especially in terms of high efficiency and high power density. Low parasitic impedance and thermal management is desired for the lower power loss and device stress. For power module with high efficiency and improved breakdown voltage, this thesis proposes a novel series-connected power MOSFETs module. Three IRF7832 MOSFE...
