Objective： To investigate menopause-related symptoms, traditional Chinese Medicine （TCM）-diagnosis and hormone status of two comparable urban samples of menopausal women, one in Essen （Germany） and the other in Shanghai （China）. Methods： Patients suffering from menopausesyndrome were recruited from the TCM-outpatient clinic of the University of Duisburg-Essen in Germany （35 subjects） and from the Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine in China （35 subjects）. The Kupperman-lndex for tracing menopausal symptoms was applied. The complete TCM-diagnosis was carried out by the same investigator in China as well as in Germany. Testosterone and estrogen blood samples were collected once from every woman. Results： There were significant differences in specific symptoms of the Kupperman-lndex, such as a higher prevalence of formication and depression in German menopausal women; whereas Chinese menopausal women suffered significantly more from vertigo, headache and paraesthesia symptoms. Concerning TCM- diagnosis, Shen （肾）-yang deficiency was diagnosed in 51.43% of the German women in contrast to 5.71 % of the Chinese women; 17.14 % of the German women were diagnosed as having Shen-yin deficiency compared to 74.29 % of the Chinese women. The German women showed significantly lower mean hormone levels for testosterone compared to the Chinese women （P≤0.0005）. Conclusions： German and Chinese menopausal women do not show different prevalence but have different patterns of menopausal symptoms. Furthermore, from a TCM point of view, German women suffer more from Shen-yang deficiency whereas Chinese women suffer more from Shen-yin deficiency syndrome. These results are supported by significantly lower levels of testosterone in German women compared to Chinese women, which, in TCM, is a characteristic of yang deficiency.

随着数值模拟技术在搅拌摩擦焊接研究中的应用日益广泛,对模型本身的准确程度要求越来越高,因而针对数值分析模型的研究显得更有意义。通过分析搅拌摩擦焊接热力耦合计算方面的相关资料,结合实际开展的搅拌摩擦焊接试验以及试验过程中对部分物理量的测量和分析,建立更加完善的搅拌摩擦焊接数值模拟模型。对生热过程、材料模型、夹具约束以及搅拌头机械载荷作用都进行细致分析和探讨,在新模型中采用被焊材料的剪切极限作为生热驱动力,考虑被焊材料的力学性能随温度和温度历史发生变化,建立夹具和试板之间的接触关系,并在力学分析模型中将搅拌头机械载荷简化考虑。利用新建立的数值分析模型对铝合金薄板搅拌摩擦焊接过程进行模拟,得到和试验结果吻合较好的温度场、残余应力和变形结果。

作者： Negash Bekena juergen Greiling Ethiopian Apiculture Board P.O. Box 2307 Addis Ababa Ethiopia

Ethiopia is an ＂apiculture country＂ with more than 10 million honey bee colonies. Ethiopia is also a ＂honey country＂; the annual honey and beeswax production potentials are 550,000 and 50,000 metric tons, respectively, with about one tenth actually produced. Since 2008, Ethiopia is EU ＂third country＂ listed for the export of honey. However, the national research system identified serious bottlenecks, such as traditional smallholder level production with very low productivity and problematic supply chain; quality issues, including adulteration; lack of access to credit; constrained input supply chain and input quality issues. This paper illustrates how quality defects have been addressed in a quality focused value chain development （VCD） approach, with focus on： creating a favorable policy ground; implementing regional, national and continental multi-stakeholder-platforms （MSPs） for dialogue; information and knowledge sharing and sector advocacy; strengthening supportive sector organizations along the value chain; networking and market intelligence, including exposition and conference organization; expansion of research centers and activities; laboratory qualification for intematioual accreditation. Many components are implemented through the largest national apiculture sector development programme called Apiculture Scaling-Up Programme for Income and Rural Employment （ASPIRE）, which transfers innovations to more than 30,000 beekeepers. Among others, ASPIRE was instrumental in qualifying national testing facilities, which in turn led to product quality improvement. However, more action is required in the fields of business-to-business （B2B） linkages, research, education and training, as well as in making so far voluntary practices mandatory. This also calls for full traceability and routine quality testing along the value chain.

AIM： To outline the surgical experience with donor liver splitting in split liver ***： From March 1 to September 1 in 2004, 10 donor livers were split ex situ into a left lateral lobe （segments Ⅱ and Ⅲ） and a right extended lobe （segments Ⅰ, Ⅳ-Ⅷ） in Medical School of Hannover, and thereafter split liver transplantation was performed successfully in 29 cases. The average age, weight and ICU slaying period of the donors were 32.7 years （25-52 years）, 64.5 kg（45-75 kg） and 2.4 d （2-8 d） ***： The average weight of the whole graft and the left lateral lobe was 2 322.6 g （956-2 665 g） and 282.8 g （298-373 g） respectively, and the average ratio of left lateral lobe to the whole graft was 0.225 （0.278-0.274）.The average graft to recipient weight ratio （GRWR） of the left lateral lobe and the right extended lobe reached 2.44% （2.22-5.42%） and 2.73% （2.32-2.30%） *** average it took approximately 205 min （85-235 rain）to split the donor liver. Five donor organs showed anatomic variation including the left hepatic vein variation in two cases, the left hepatic artery variation in two cases and the bile duct variation in one ***： Split liver transplantation has become a mature surgical technique to expand the donor pool with promising results. In the process of graft splitting, close attention needs to be paid to potential anatomic variations,especially to variations of the left hepatic vein, the left hepatic artery, and the bile duct.

To meet the rising demand of performing complex tasks in a highly technologized world,the development of mechatronic systems faces two major challenges:First,the system is integrated in a fast changing environment and has to cope with dynamically modified tasks and *** the same time,the development of new methods has to be fast,cost-effective and *** taking care of both aspects simultaneously,simulations have become an acknowledged tool to cost-effectively and rapidly test and optimize new solutions for complex mechatronic systems,as they are common in,e.g.,***,simulation methods are specialized for one purpose and thus used as a stand-alone tool to analyze the behavior of single components or certain aspects of the whole *** with size and complexity of the system,the susceptibility to errors rises when the interaction between components *** a component shows minimal deviations to its nominal behavior,huge interdependencies between components of complex systems might cause system *** structural behavior of a single component is therefore as crucial to the functionality of the whole system as the interplay of all *** aspects have to be analyzed in parallel,which is nowadays barely ***,this work presents the integration of structural simulations into the overall *** developed approach consists of a concept,an implementation and the validation for an automated bidirectional interaction to integrate results from Finite Element Analysis(FEA)into an existing,real-time capable Overall System Simulation for mechatronic systems in general and robotics in particular.
