for the first time we have used eyelid skin expansion to facilitate reconstruction of selected patients with shortage of lid skin (e.g. for burn scar and after excision of tumors). this method allows for a controlled increase in skin, need for reconstruction, and offers many advantages over grafted skin transfered from a distance. color, texture, thinness, delicacy and adnexal structures are ae...

Food availability is expected to trigger hibernation and torpor (ie heterothermy) use. Yet, laboratory experiments under controlled conditions dominate, and this hypothesis remains largely untested under natural conditions. Further experimental manipulations of food availability must therefore be conducted in the wild, accounting for other covarying environmental stressors.

The issue of whether government capital is productive has received a great deal of attention recently, yet empirical analyses of public capital productivity have generally been limited to the official capital stock estimates available in a small sample of countries. Alternatively, many researchers have investigated the output effects of public investment—recognizing that investment may be a poo...

Recently four different papers have suggested that the supervaluational solution to the Problem of the Many is flawed. Stephen Schiffer (1998, 2000a,b) has argued that the theory cannot account for reports of speech involving vague singular terms. Vann McGee and Brian McLaughlin (2000) say that theory cannot, yet, account for vague singular beliefs. Neil McKinnon (2002) has argued that we canno...

neurotrauma is one of the main medical problems that affect considerable number of population especially young persons in all countries. neurotrauma not only is a serious threat for life but also creates various disabilities and consequently imposes large costs to society. following central nervous system (cns) injury, tissue damage occurs via primary and secondary mechanisms. despite many atte...

Available fresh water resources are subjected to an ever-increasing pressure due to extensive agricultural water demand for irrigated lands. A long-term perspective in shortage of fresh water resources, especially in arid and semi-arid area, highlights an urgent solution for innovative irrigation strategy and agricultural water management. This paper is a review on the wide applications of the ...

Lakes are suffering from different stress factors and need to be restored using different approaches. The eutrophication remains as the main water quality management problem for inland waters: both lakes and reservoirs. The way to curb the degradation is to stop the nutrient sources and to accelerate the restoration with help of in-lake technologies. Especially lakes with a long retention time ...

the outflow of nurses to more affluent countries was a serious problem, worsening the shortage that already exists.” The Ghana Registered Nurses Association reported that in 2000, some 500 nurses left Ghana for higher pay in other countries. This is three times the number of nurses that left in 1999, and double the number of nurses that Ghana graduated in that same year. Reports from Europe are...
