Lack of Long-Lasting Consequences of Starvation on Eating Pathology in Jewish Holocaust Survivors of Nazi Concentration Camps.

The purpose of the present study was to investigate whether Holocaust survivors will show the same eating pathologies that were found in other participants who had also undergone starvation. Fifty-five Holocaust survivors and 43 matched control participants answered a questionnaire designed to explore eating problems and pathologies described in the literature as lasting for decades after a period of severe food restriction. Confirmation of the survivors' reports was obtained from their children. No significant differences in current eating habits were found between the Holocaust survivors and their matched controls. Prolonged starvation in Holocaust survivors did not lead to disordered eating habits in the sample. These results conflict with the notion that severe starvation consistently leads to food preoccupation and disordered eating. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Cover Picture: Chemical Restriction: Strand Cleavage by Ammonia Treatment at 8‐Oxoguanine Yields Biologically Active DNA (ChemBioChem 7/2003)

The cover picture shows a chemical restriction method in which DNA double strands are cleaved at the position of the artificial base 8‐oxoguanine (G^oxo). As as result of the mild cleavage conditions, the DNA fragments remain biologically active and can be used in gene cloning experiments. As an example, the lac Z′ gene was amplified by PCR with 8‐oxoguanine‐modified primers, restricted by treatment with ammonia, ligated into a plasmid vector, transformed in Escherichia coli cells, and screened for blue colonies. This method guarantees efficiencies comparable to the standard cloning procedure, and allows the design of any 3′ overhang, independent of the sequence of the cloned DNA.

The Relationship of Activity Restriction and Replacement With Depressive Symptoms Among Older Adults.

Activity restriction is known to mediate the disease-depression relationship. Data from 423 older Israeli adults showed that having to give up activities because of failing health was related to more depressive symptoms (DS), whereas satisfactorily replacing these activities was related to DS levels comparable to those of healthier older adults. Giving up and replacing activities mediated, in part, the effect of functional limitations on DS, after controlling for health status, demographics, and resources. Such questions about activities given up and replaced could contribute to the means of assessing the extent and impact of functional limitations on older adults.

爆力运矿采矿法的改进与完善

爆力运矿采矿法能较好地解决倾斜中厚矿体采场内矿石运搬和作业安全问题，具有采切比小、矿石损失贫化低、经济效益好等优点。但是由于各种原因一直未能推广应用。本文针对制约爆力运矿采矿法发展的各种因素，提出了改进的措施和方法，并提出了今后的发展方向和设想。     

从陶瓷仕女图纹看古代女性文化

仕女艺术源远流长。纵观陶瓷仕女图纹，一幅幅优美的画面，一个个靓丽的仕女背后，实则浸染了几千年封建伦理道德意识对女性的观赏和消费价值的倾向，隐含着男权社会对女性的身体乃至精神的种种禁锢和束缚。这些凄美的仕女图纹深深折射出古代女子的无尽帐惘和万般沉抑之情。     

空间球形物体自动定位方法研究

利用双目立体视觉技术对空间物体进行定位的一个难点在于特征点的选择和匹配，常用的方法是选择一幅图像中物体的形心为特征点，然后根据灰度或者颜色值在另外一幅中进行匹配。为了达到较好的精度，所用的匹配算法都比较复杂，并且当物体表面颜色分布均匀时错误匹配率较高。针对球形物体，本文提出基于形心几何匹配的定位方法，避开了常规匹配方法所面对的难题，经过试验验证，效果很好。
