The breakdown property of oil-impregnated paper is a key factor for converter transformer design and operation, but it is not well understood. In this paper, breakdown voltages of oil-impregnated paper were measured at different temperatures. The results showed that with the increase of temperature, electrical, electro-thermal and thermal breakdown occurred successively. An electro-thermal brea...

rainfall erosion processes a long with the rainfall characteristics can be affected by soil properties. the study was conducted to investigate the susceptibility of the aggregates in different soil textures to the rainfall erosion processes. the experiment was done on thirty soil samples recognized in four soil textures with different replications as the completely randomized design. ninety box...

This paper describes using breakdown [24] in players’ use of video games to analyze the learnability of these games. This paper emphasizes the importance of two levels of breakdown that support (breakdown of interaction) and break immersion (breakdown of illusion) in games respectively [17]. I conducted a study to investigate learning in games. From this study, I constructed a framework of nine...

developing a culture system for preantral follicles has important biotechnological implications due to the potential to produce a large number of oocytes for embryo production and transfer. to accomplish this goal, the present study was aimed to culture preantral follicles in the presence of different media, sera and fsh concentrations. six-week-old preantral follicles (95 ± 5 µm) were cultured...

objective: mitochondria is a critical organelle within the cell and has important role in the oocyte development, thus the aim of this study was the comparison of mitochondrial distribution within the mouse oocyte at germinal vesicle (gv), germinal vesicle breakdown (gvbd) and metaphase ii (mii) stages using laser confocal microscopy (lscm). materials and methods: after superovulation of adult...

VANET in hilly terrains suffers frequent signal breakdown, interferences and other hinderances, affecting QoS (Quality of service). In this paper various Ad hoc routing protocols are compared for IP, Throughput FIFO taking to consideration parameters real traffic scenarios like altitude, nodes, speed, data size & weather mobility model using Qualnet as a simulation tool at higher altitude 1...

In this work, gas discharge ignited by girotron radiation with frequency 1 THz was carried out. Breakdown curves were calculated both for selfignited and initiated discharges. There shown that in a case of breakdown the pulse duration longer than several microseconds electric field threshold is same as continuous wave breakdown. Also, possibility using terahertz gyrotron source targets on insta...

BMJ VOLUME 318 15 MAY 1999 www.bmj.com General practitioners in Great Britain should not be allowed to remove patients from their lists without giving reasons for so doing to the health authority or without the authority’s permission, a report from the select committee on public administration said this week. The committee, which was commenting on the annual report of the health service ombudsm...

Several data sets for the electrical breakdown in air of single-wall carbon nanotubes (SWNTs) on insulating substrates are collected and analyzed. A universal scaling of the Joule breakdown power with nanotube length is found, which appears to be independent of the substrate thermal properties of their thickness. This suggests that the thermal resistances at SWNT-insulator and at SWNT-electrode...
