A "Watershed-Scale Sediment Information Network" (WaSSIN), designed to complement UNESCO’s International Sedimentation Initiative, was endorsed as an initial proj.ct by the World Association for Sedimentation and Erosion Research. WaSSIN is to address global fluvial-sediment information needs through a network approach based on consistent protocols for the collection, analysis, and storage of fluvial-sediment and ancillary information at smaller spatial scales than those of the International Sedimentation Initiative. As a second step of implementation, it is proposed herein that the WaSSIN have a general structure of two components, (1) monitoring and data acquisition and (2) research. Monitoring is to be conducted in small watersheds, each of which has an established database for discharge of water and suspended sediment and possibly for bed load, bed material, and bed topography. Ideally, documented protocols have been used for collecting, analyzing, storing, and sharing the derivative data. The research component is to continue the collection and interpretation of data, to compare those data among candidate watersheds, and to determine gradients of fluxes and processes among the selected watersheds. To define gradients and evaluate processes, the initial watersheds will have several common attributes. Watersheds of the first group will be: (1) six to ten in number, (2) less than 1000 km2 in area, (3) generally in mid-latitudes of continents, and (4) of semiarid climate. Potential candidate watersheds presently include the Weany Creek Basin, northeastern Australia, the Zhi Fanggou catchment, northern China, the Eshtemoa Watershed, southern Israel, the Metsemotlhaba River Basin, Botswana, the Aiuaba Experimental Basin, Brazil, and the Walnut Gulch Experimental Watershed, southwestern United States.

To the Editor：We read with outstanding interest the article by Celik et al. It is the first external description of the Hamburg＇s preoperative pancreatic resection （PREPARE） score since it was published in 2014 by Uzunoglu et al. According to the latter authors, it is necessary to stratify risk of maj.r morbidity and mortality before performing a pancreatic resection, and PREPARE score is a simple index, validated in a multicenter cohort of patients undergoing this group of technically demanding procedures.

最近美国航空与空间计划署(NASA)开展的卡西尼—惠更斯外空探测计划发现,在直径为500km的卫星——土卫二上存在水冰和间隙泉的喷发活动。这一现象和在火星上工作的"机遇号"和"勇气号"漫游车所发现的液态水一起,证明了除地球以外的其他星球上过去和现在都存在水,其中的一些星体还有火山活动的证据,这意味着这些星球上可能存在过热液活动地质过程。讨论了火星、木卫二和土卫二可能存在的热液系统类型。这些热液系统类型是根据地球上的构造背景进行相似性研究后得出的,例如海底、火山和裂谷系统。将东非裂谷和贝加尔湖裂谷系统与火星Tharsis高原上巨大的水手大峡谷进行了对比,这些地区都是由地幔柱作用下构造—热液活动导致的地壳抬升、火山和裂谷作用。在火星上,地下冰或低温层会在火山活动和(或)小行星或彗星撞击作用下溶解而形成热液对流。

Background:There is a lack of rigorous research investigating the factors that influence scar outcome in children. Improved clinical decision-making to reduce the health burden due to post-burn scarring in children will be guided by evidence on risk factors and risk stratification. This study aimed to examine the association between selected patient, inj.ry and clinical factors and the development of raised scar after burn inj.ry. Novel patient factors were investigated including selected immunological co-morbidities (asthma, eczema and diabetes type 1 and type 2) and skin pigmentation (Fitzpatrick skin type). Methods:A prospective case-control study was conducted among 186 children who sustained a burn inj.ry in Western Australia. Logistic regression was used to explore the relationship between explanatory variables and a defined outcome measure:scar height measured by a modified Vancouver Scar Scale (mVSS). Results:The overall correct prediction rate of the model was 80.6%;80.9%for children with raised scars (>1 mm) and 80.4%for children without raised scars (≤1 mm). After adj.stment for other variables, each 1%increase in%total body surface area (%TBSA) of burn increased the odds of raised scar by 15.8%(95%CI=4.4-28.5%). Raised scar was also predicted by time to healing of longer than 14 days (OR=11.621;95%CI=3.727-36.234) and multiple surgical procedures (OR=11.521;1.994-66.566). Conclusions:Greater burn surface area, time to healing of longer than 14 days, and multiple operations are independently associated with raised scar in children after burn inj.ry. Scar prevention strategies should be targeted to children with these risk factors.
