全波列声波测井正广泛用于确定地层动弹横量的土木工程中。有时横波幅度太小以致没有精确的波至时间,在此情况下,使用 christensen 方程可以根据纵波速度和地层密度来预测横渡速度。本文通过不同的天然材料在野外和实验室研究结果间的关系,对该方程的特性作了大量的研究。结果表明横波速度测量值和预测值的不同是由岩性变化引起的。这个方程不适用于未固结的沉积物。动弹横量反映了这些差别。不同横波速度对体积模量的影响最小。泊松比的预测值与测量值之间不存在任何联系。如果做适当的岩性校正,该方程的应用将得到改进。

Natural Science 2011年第7期3卷 530-534页

作者： Gisel chenard díaz Rodolfo Salazar Perez Neyda de la c. Om Tapanes donato Alexandre Gomes Aranda Angel Almarales Arceo 不详

Hydrolysis reactions are of major importance to the oleochemical industry in the prod.c.ion of fatty acid and their derivates. Hydrolysis of triglyceride from vegetable oil has been studied under various parameters such as: heterogeneous catalyst, temperature, reaction time and agitation speed. during the hydrolysis of soybean oil and tallow using nickel catalysts on alumina support was verified that the glycerol prod.c.d worked as hydrogen donor, allowing the hydrogenation of unsaturated fatty acids prod.c.d. Maximum conversion was achieved in 3 hours, catalysts 25% NiO/Al2O3, temperature of 250oc and 270oc and 250 rpm.

An exploration of violence, mental health and substance abuse in post-conflict Guatemala

Guatemala’s 36-year civil war officially ended in d.c.mber 1996 after some 200,000 deaths and one million refugees. despite the ceasefire, Guatemala continues to be a violent country with one of the highest homicide rates in the world. We investigated potential associations between violence, mental health, and substance abuse in post-conflictGuatemalausing a community-based survey of 86 respondents living in urban and ruralGuatemala. Overall, 17.4% of our respondents had at least one, direct violent experience during the civil war. In the post-conflict period, 90.7% of respondents reported being afraid that they might be hurt by violence, 40.7% screened positive for depression, 50.0% screened positive for PTSd, and 23.3% screened positive for alcohol dependence. Potential associations between prior violent experiences during the war and ind.c.tors of PTSd and aspects of alcohol dependence were found in regression-adjusted models (p certain associations between prior civil war experiences, aspects of PTSd and alcohol dependence in this cohort are remarkable, raising concerns for the health and safety of the largely indigenous populations we studied. Higher than expected rates of depression, PTSd, and substance abuse in our cohort may be related to the ongoing violence, injury and fear that have persisted since the end of the civil war. These, in turn, have implications for the growing med.c.l and surgical resources needed to address the continuing traumatic and post-traumatic complications in the post-conflict era. Limitations of the current study are discussed. These findings are useful in beginning to understand the downstream effects of the Guatemalan civil war, although a much larger, randomly sampled survey is now needed.

我们在一个减压cVd反应器中,于700～750℃下用四乙氧基硅烷(TEOS)分解法,在硅衬底上淀积出了二氧化硅膜。淀积速率为200～300埃/分。在能装载100片的淀积区,淀积膜厚的均匀性优于1％。台阶覆盖性良好,缺陷密度很低,膜的应力是压应力而且很小。膜的折射率,红外质谱和密度与常压淀积的二氧化硅膜相同。系统中添加磷化物使淀积速率增加,膜厚的均匀性变坏。因此,这种反应并不能适用于淀积集成电路所用的掺磷二氧化硅膜;然而,对非掺杂的二氧化硅膜淀积工艺来说,这种反应似乎是一个很好的工艺过程。
