This article presents the results of the research carried out for modernization of the medium voltage metal enclosed switchgear for secondary distribution of electricity. The metal enclosed switchgear upgrading is based on the patent proposal no. A/00230/14.03.2013 for this purpose and aims at increasing the reliability in the supply of electricity. The modernization consists in eliminating the existing...
This article proposes the research and simulation of general bars of medium voltage metal enclosed switchgear, made of aluminum round bar with copper contacts, with a view to finding a similar or even more convenient solution than that of copper bars, both from a technical and economic point of view. The objective is heat distribution for current passing, in the bar and especially in contacts, under...
This article presents a system able to control in phase a switching element capable of high currents and voltages switching. Its use is presented for the assessment of the transient response in capacitive instrument transformers. Because of the capacitors used for its construction, the high frequency signals (especially in network switching) are transmitted on the measurement windings. To prevent...
This article presents the result of the research carried out for the modernization of the constructive solutions for classic current limiting fuses defined in IEC 60282-1 /2009 used for the protection of electric circuits pertaining to the distribution of electric energy. The modernization of the current limiting fuses, without silver and copper consumption, for the protection of high voltage electric...
Despite decades of study, the etiology of brain cancer remains elusive. However, extensive molecular characterization of primary brain tumors has been accomplished, outlining recurrent features that are proving useful for devising targeted therapies. There are far too few patients available for comparing the efficacy of therapeutic combinations, especially when variations in dosing, frequency, and...
Japanese encephalitis (JE) is the most common viral encephalitis in Asia. IC51 is a new Vero cell-derived, inactivated JE virus vaccine with non-inferior immunogenicity (after 2 months) compared to the US-licensed vaccine JE-VAX ® (mouse brain-derived, inactivated) and with a more convenient (two injections instead of three) intramuscular dose schedule. Adult subjects from two studies were...
