Assessment and management of fetal agenesis of the corpus callosum

Prenatal counselling for fetal agenesis of the corpus callosum is difficult as the prognosis until now has been so uncertain. We have reviewed the current world English literature to provide the best probabilistic information for prospective parents. In total, there are 70 cases where the diagnosis was made prenatally. The diagnosis of apparently isolated agenesis of the corpus callosum (in the absence of other sonographically detectable anomalies) appears to carry an excellent prognosis, with an 85 per cent chance of a normal developmental outcome and a 15 per cent risk of handicap. Fetal karyotyping is recommended as there is a 1 in 10 risk of aneuploidy. If other anomalies are detected prenatally, the outcome is very poor. Termination of pregnancy is advised in these circumstances.

Mitigation and adaptation synergy in forest sector

Mitigation and adaptation are the two main strategies to address climate change. Mitigation and adaptation have been considered separately in the global negotiations as well as literature. There is a realization on the need to explore and promote synergy between mitigation and adaptation while addressing climate change. In this paper, an attempt is made to explore the synergy between mitigation and adaptation by considering forest sector, which on the one hand is projected to be adversely impacted under the projected climate change scenarios and on the other provide opportunities to mitigate climate change. Thus, the potential and need for incorporating adaptation strategies and practices in mitigation projects is presented with a few examples. Firstly, there is a need to ensure that mitigation programs or projects do not increase the vulnerability of forest ecosystems and plantations. Secondly, several adaptation practices could be incorporated into mitigation projects to reduce vulnerability. Further, many of the mitigation projects indeed reduce vulnerability and promote adaptation, for example; forest and biodiversity conservation, protected area management and sustainable forestry. Also, many adaptation options such as urban forestry, soil and water conservation and drought resistant varieties also contribute to mitigation of climate change. Thus, there is need for research and field demonstration of synergy between mitigation and adaptation, so that the cost of addressing climate change impacts can be reduced and co-benefits increased.     

克拉玛依市水,土资源承载力与城市发展对策研究

在城市可持续发展的进程中，克拉玛依已具备了许多有利条件，但同时也存在一些限制性２。文章重点研究了克拉玛依水、土地资源的承载力与城市发展的关系，从水资源供需平衡，水资源承载力与城市发展规模控制、土地资源人口承载力、工业用地规模、居住用地规模、绿化用地规模和环境管理等方面提出了对策。     

南京东郊石炭纪威宁期的风暴沉积

南京东郊石炭纪威宁期碳酸盐岩地层中普遍见有风暴沉积,以有突变的底界和底面构造、贝壳层、粒序层以及在风暴低能快速堆积条件下所形成的遮蔽构造等为基本鉴别要素,这些要素的不同组合构成的剖面结构可划分为五种类型,据此笔者提出本区风暴沉积的综合剖面结构。     

西江沿岸地带工业资源开发策略

西江沿岸地带是一个工业不发达的待开发民族区域,但它拥有多方面工业资源优势,而且工业开发环境条件良好。作者认为,优势的工业资源开发必须在全方位开放与资源深度利用的基础上以轻型为主导的策略,重点建设制糖、水果加工、水电、有色金属为主的原材料及加工等若干工业基地。布局上以西江干流和区内铁路干线为“轴”,结合重点工业“点”,稳定提高中部,重点开发东部,创造条件开发西部,实现“点轴结合,逐步推进”的工业资源区域开发策略。     

生态农业建设中的水资源生命周期及系统功能响应

论文从生命周期角度，对原先自然环境恶劣、通过生态农业建设取得了良好效果的3个生态农业县的水资源利用进行了全过程研究。结果表明，水资源生命周期过程的进展情况受多种因素影响。目前，各生态农业县水资源生命周期过程仍处在发育的初级阶段。这一过程的完整性与系统生态、经济和社会功能的提高成正比。
