In order to investigate pluvial lakes in the Gobi two places were selected for field studies: Khongoryn Els inSouth- and Mongol Els in West-Mongolia. In the eastern and central parts of Khongoryn Els two small endorheic basins,Bayan Tukhem and Khongoryn Gol depressions were studied. Pluvial lake deposits and beach ridges both supposedly mid-Holocenein age give evidence of a 9m and a 15m deep freshwater lake,respectively. Today both depressions are nearlydried out and exposed to wind deflation. A different situation was found at Uujin Sair river valley which cuts through thedune field at its lowest and narrowest (3 km) part. Here, a 22.5 m thick fossil accumulation of at least 20 layers of fine sand(dune sand)alternating with silt(fluvial playa sediment)was exposed and OSL dated. 12 dates ranging between 14ka and17ka reveal the accumulation as Late Glacial which correlates well with the aridity at that time reported for Central Asia byseveral authors. Interpreting the dates it seems obvious that the whole sediment was quickly deposited in a period of about16ka,and shortly after dissected by the Uujin Sair during a similar short time due to increasing humidity of the *** situation was found at the eastern rim of Mongol Els. Two rivers,Shurgiyn Gol and Zavran Gol are impinging hereon the high dunes which have damed both rivers in the past. A younger, shallow lake existed during mid-Holocene( ^(14)C-dated to some 5.5ka)and a large, 17m deep lake( ^(14)C -- dated to some 39ka) probably during stage 4. Expected OSLdates will hopefully support this hypothesis. Anyhow, the palaeogeography of the dune field was different from today; itmoved eastward daming the large river Shurgiyn Gol.

斯图加特的破晓时分，天气已经转凉，寒气形成的薄雾笼罩下的车辆已经排成了一队队长龙，坐在车里的大人们显得很不耐烦，嘴上一个劲儿地抱怨，而孩子们则大都茫然地望着车外。

天刚破晓，一辆身披保时捷外套的大型拖车冲进了我的视野之中，卸货坡道缓缓落下，蒙布随即升起。一辆白得耀眼的911被推了下来，低垂的前身坝从距离坡面仅仅几毫米的空中划过，经过启动马达的多次催促，发动机终于咆哮着醒了过来，它时下正在持续地以一种焦躁不安的赛车怠速运转着，技术人员纷纷凑到近前，转着圈排查是否存在机械异动，排气管漏气和供油不畅的现象，测过胎压，抹净风挡，他们拉开左侧车门，招呼我坐进去……

Resective epilepsy surgery is an elective therapy indicated in focal epilepsy patients who are resistant to pharmacotherapy. Every effort should be undertaken to perform the procedures as safe and less traumatic as possible. Neuronavigation could represent a suitable tool to reduce surgical morbidity and increase surgical radicality. Here, we present a series of 41 patients who were operated on for medically intractable epilepsy using neuronavigation. Overall, complication rate was 17% with a favourable seizure outcome of 88% (Engel’s class I/II). Our data suggest that neuronavigation is a valuable surgical technique to accomplish a favourable outcome in epilepsy surgery.
