BACKGROUND There are a number of conflicting studies on the prevalence of intestinal parasitic infections in HIV infection with regards to different seasons. This study was conducted to determine seasonal influence on the prevalence of intestinal parasitic infections in HIV-positive persons in Benin City, Nigeria. METHODS Stool specimens from 2000 HIV-positive patients and 500 controls (HIV-n...

Abstract: The analysis of the effect of the parasitic capacitors of the split capacitor array on the successive approximation register analog-to-digital converter’s charachteristics is presented. The Verilog-A model of the split capacitor array is developed based on the analysis. The model takes the effects of parasitic capacitors into account, and the values of these parasitic capacitors can b...

To mitigate the radio-frequency (RF) performance degradation caused by electrostatic discharge (ESD) protection device, low capacitance (low-C) design on ESD protection device is a solution. With the smaller layout area and small parasitic capacitance under the same ESD robustness, silicon-controlled rectifier (SCR) device has been used as an effective on-chip ESD protection device in RF ICs. I...

Only a few food-borne parasitic zoonoses have been reported in Indonesia. The most frequently observed food-borne parasitic diseases are: toxoplasmosis, taeniasis and cysticercosis. Little data are available on other parasitic zoonoses in Indonesia. Taeniasis has been reported in nine provinces. Toxoplasmosis in humans, with prevalence rates ranging from 1 to 60%, has been reported in 12 provin...

Parasitic exploitation occurs within and between a wide variety of taxa in a plethora of diverse contexts. Theoretical and empirical analyses indicate that parasitic exploitation can generate substantial genetic and phenotypic polymorphism within species. Under some circumstances, parasitic exploitation may also be an important factor causing reproductive isolation and promoting speciation. Her...

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...

One of the most critical components in a step-up design like Figure 1 is the transformer. Transformers have parasitic components that can cause them to deviate from their ideal characteristics, and the parasitic capacitance associated with the secondary can cause large resonating current spikes on the leading edge of the switch current waveform. These spikes can cause the regulator to exhibit e...

Sir, The recent report on ‘Acute appendicitis and Schistosomiasis’ is very interesting.1 Figueiredo et al noted for ‘possibility of finding more patients with concurrent appendicitis and schistosomiasis’.1 In fact, the parasitic acute appendicitis is not an uncommon problem in the tropical world. According to the recent report by Jada et al, it was reported that ‘among 100 specimens, 48 faecoli...

Parasitic dinoflagellates have recently emerged as significant disease agents of commercially important crustaceans. For example, epizootics of Hematodinium have seriously affected certain crab and lobster fisheries. The parasitic dinoflagellates of crustaceans are, however, relatively unknown. Marine crustaceans are parasitized by two orders of dinoflagellates: the Blastodinida and the Syndini...
