After explaining the basic operation of a SiC JFET plus silicon MOSFET cascode circuit, the dynamics of cascode switching will be discussed and the use of a QRR tester to evaluate the reverse-recovery characteristics of a cascode circuit will be explained. A comparison of the cascode’s reverse recovery with that of a SiC MOSFET reveals that the JFET cascode actually performs better than the SiC...

One of the most important items of modern agriculture is the reduction of environmental impact thanks to the integration of new cultivation and protection techniques. Therefore it is important to optimise the use of chemicals and pesticides. We found that some coadjutants applied in tank mix with fungicides on sugar beet protection improve the effectiveness of active principles in cercospora le...

background pyrocatechol or 1, 2-dihydroxybenzene, or 2-hydroxyphenol is considered as apriority pollutant since it is harmful to organisms at low concentrations, and has been classified as hazardous pollutants. objectives the objective of this study was to examine whether azolla filiculoides, is able to remove pyrocatechol from aqueous solutions. materials and methods this study is an experimen...

Notwithstanding the risky, unconventional, and demanding nature of Special Operations Forces (SOF) missions, the assessment and selection of SOF candidates should be governed by the same principles that prevail in the selection of candidates in other sophisticated organizations. This chapter applies western industrial psychology guidelines and procedures to SOF by providing a general overview o...

Within recent years, various concepts have arisen in environmental management that directly address the flow of material (and information) along life cycles or supply chains and thereby relate to inter-organizational management aspects. These include industrial ecology (IE), life-cycle management, closed-loop supply chains, integrated chain management and green/environmental or sustainable supp...

By using multi-agents system model simulation method, this paper tries to reveal the key driving force for the evolution of industrial clusters under the dynamic development of the external environment and internal innovation. Also, how important role of policy recommendations is proved for the regional industrial development. For the purpose of studying the evolution of industrial clusters, a ...
