sunflower (helinathus annuus) is a susceptible host to the holoparasite hemp broomrape (orobanche ramosa) in central parts of iran, causing yield loss due to severe infestations. a field study was conducted in 2006 to evaluate the efficacy of glyphosate for controlling the parasitic weed hemp broomrape in sunflower. glyphosate was applied once or twice at five rates ranging from 0.075 to 0.450 ...

in this study parasitic infection of bobwhite and japanese quails were clarified in farms of garmsar city in province of semnan. forty quails from two breeds randomly were selected and they examined to identify all internal and external parasites .finding was shown that five percent of the quails examined harbored one or more species of helminthes. two cestodes, raillietina echinobothrida and r...

Abstract: We proposed a concept of balanced switching converter circuit, which is an effective way to reduce the common-mode conducted noise by current cancellation. In this paper, the path of the noise current in a balanced boost converter circuit is investigated using a current probe. By measuring current waveforms and frequency spectra of the parasitic capacitances and the frame ground line,...

Several reports have suggested that the high prevalence of epilepsy in sub-Saharan Africa is associated with the high prevalence of parasitic infections affecting the central nervous system. Though epidemiological evidence suggests an association between parasitic infections and epilepsy, the biological causal relationship has not been fully demonstrated for many of these infections. The object...

Obligate avian brood parasites show dramatic variation in the degree to which they are host specialists or host generalists. The screaming cowbird Molothrus rufoaxillaris is one of the most specialized brood parasites, using a single host, the bay-winged cowbird (Agelaioides badius) over most of its range. Coevolutionary theory predicts increasing host specificity the longer the parasite intera...

In digital current mode controlled DC-DC converters, conventional current sensors might not provide isolation at a minimized price, power loss and size. Therefore, a current observer which can be realized based on the digital circuit itself, is a possible substitute. However, the observed current may diverge due to the parasitic resistors and the forward conduction voltage of the diode. Moreove...

1800A/3.3kV IGBT module with the highest current rating was developed. Advanced Trench HiGT structure was used to achieve low loss characteristics. Module electrical and thermal characteristic were optimized in order to reduce thermal resistance and parasitic inductance. The current ratings of new IGBT module can be increased by 20% from the conventional product type.

The current public health status in Malaysia of some of the food-borne parasitic zoonoses, such as angiostrongyliasis,trichinellosis, toxoplasmosis, sarcocystosis, and other food-borne zoonoses, such as pentastomiasis, is presented.

This article gives an overview of the topic, with emphasis on current concepts and management of the clinical situations in question, in particular the concepts related to treatment. An extensive review of the etiology and monitoring of patients with non-parasitic splenic cysts is also made. These reports are derived from major clinical studies published in the current medical literature.

The loss of key biosynthetic pathways is a common feature of important parasitic protists, making them heavily dependent on scavenging nutrients from their hosts. This is often mediated by specialized transporter proteins that ensure the nutritional requirements of the parasite are met. Over the past decade, the completion of several parasite genome projects has facilitated the identification o...
