Electrospraying has attracted the attention of many researchers, ranging from analytical chemists to physicists, not only because of the rich physics associated with it, but also due to its wide-ranging applicability. Therefore, considerable research has been devoted to exploring this interfacial phenomenon. However, there still are areas of electrospraying that have remained unexplored. Until ...

abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...

studied. The experimentally obtained values of transport current exceed the normal phase minimum propagation current substantially. The current-voltage characteristics of the investigated samples have been studied. I t is shown that the relatively high value of the maximum transport current is attributed, under the given experimental conditions, to the behaviour of the current-voltage character...

aspergillus terreus is emerging as an etiologic agent of invasive aspergillosis among patients undergoing cancer chemotherapy, haematopoetic stem-cell transplantation, or solid organ transplantation worldwide. infections caused by aspergillus terreus has become important due to less susceptibility to antifungal drags, resistant to amphotericin b and therefore, poor clinical outcome and higher m...

The rise of satellite altimetry is a revolution in the ocean sciences. Due to its global coverage and its high resolution, altimetry classically outperforms in situ water level measurement. Ekman and geostrophic currents are large parts of the ocean’s current, playing a vital role in global climate variations. According to the classic oceanography, Ekman and geostrophic currents can be calculat...

Phase-control of a magnetron is studied via simulation using a combination of a continuous current source and a modulated current source. The addressable, modulated current source is turned ON and OFF at the magnetron operating frequency in order to control the electron injection and the spoke phase. Prior simulation work using a 2D model of a Rising Sun magnetron showed that the use of 100% mo...

Psoriasis is a chronic, genetically determined skin disease. A variety of biochemical and molecular biological alterations have been identified, but the pathogenesis of psoriasis is still not clear. For patients with mild to moderate psoriasis, topical therapies are generally used. However, approximately one-third of the patients have a moderate to severe psoriasis and need a systemic therapy. ...
