We build upon recent literature to do several exercises to assess benefits and costs of the brain drain to Africa. Contrary to a lot of the worries expressed in the media and in aid agencies, the Brain drain is probably a net benefit to the source countries. We make several arguments: (1) the African brain drain is not large enough to have much effect on Africa’s skill gap relative to the rest ...

Continuous-wave green laser-crystallized (CLC) single-grain-like polycrystalline silicon n-channel thinfilm transistors (poly-Si n-TFTs) demonstrate the higher electron mobility and turn-on current than excimer laser annealing (ELA) poly-Si n-TFTs. Furthermore, high drain voltage accelerates the flowing electrons in n-type channel, and hence the hot-carriers possibly cause a serious damage near...

In Egypt, the Water Quality of fresh waterways, especially those receiving wastewater from agricultural drainage such as El-Salam Canal is every, now, and then, precarious for some water use. Although, Egypt relies on this marginal quality in order to cover resulting gap between needs supply. The reuse appears be one most promising, practical, economical means increasing Egyptian budget which G...

Published information on Cuhx quinqztifmciutw Say repeatedly affirms that this species responds directly to cool temperatures by extending the length of its life cycle, rather than by interrupting development with a true state of diapause (Eldridge 1966, 1968; Wilton and Smith 1985). Observations of winter activity in populations of Cx. quinquefmciatus in Texas (Hayes and Hsi 1975, Strickman 19...

This paper shows that the migration of educated workers abroad can convey a positive signal about the ability of native talents. When there is uncertainty about the distribution of talents in the donor country and/or about the effectiveness of its education system, migrants may reveal information about their talents. This may enhance the reputation of the workforce both in the host country and ...

A minimally invasive technique of chest drain insertion using the Mini Step bladeless trocar is described. Thirty-one chest drain insertions were performed with this technique between January 2007 and December 2009. It is a safe, efficient, fast, and easily acquired means of chest drain insertion in children, which has a high success rate and minimal morbidity. Overwhelmingly positive responses...
