introduction: biological effects of magnetic fields have been investigated by scientists for many years and a vast amount of research using different frequencies and intensities have been performed on humans and laboratory animals. the results of these studies, which have mostly been done by applying high frequencies, have shown that electromagnetic fields are effective on structure and functio...

An unsteady mixed convection flow of Williamson nanofluid over a stretchable surface embedded in porous medium is scrutinized numerically. Here the characterized by Darcy Forchheimer model under influence magnetic field. Heat transfer analysis with two different conditions namely, prescribed temperature (PST) and heat flux (PHF) are taken into account. The evolved mathematical numerically solve...

It is critically important for plants to control the trade-off between normal growth and pathogen immunity. However, underlying molecular mechanism remains largely unknown. Here we report such a controlled by WRKY70 its partner CHYR1 in Arabidopsis. We found that both levels of target gene SARD1 phosphorylated forms were increased WRKY70OE upon Pst DC3000 infection. Mechanistically, phosphoryla...

In the last decade most of the development and research in telecommunications moved from hardware design to software applications. Nowadays, most of the new features and services are introduced through software development. Due to strong competition on the telecommunication market telecommunication companies are forced to develop their products in the shortest possible time. The verification of...

this paper presents a novel control method to improve the efficiency of low-voltage dc-dc converters at light loads. pulse width modulation (pwm) converters have poor efficiencies at light loads, while pulse frequency modulation (pfm) control is more efficient for the same cases. switching losses constitute a major portion of the total power loss at light loads. to decrease the switching losses...

broadcast digitalization with its enormous benefits to the broadcasting industry will improve the quality of content of programs delivered by television stations. africa has a switchover date of june, 2017. for nigerians to have access to television broadcast once the switch over is completed, they must purchase high definition television sets or the set-up box. the awareness among urban dwelle...

background: defects in b cell class switch recombination (csr) are a heterogeneous and yet very uncommon group of disorders which all have a genetic basis uniformly leading to hyper igm (higm) syndrome. due to the rare frequency of these conditions, a very small number of case series have been conducted on the affected patients. objective: to shed some light on the morbidity and mortality regar...
