Solar Trade War Ⅱ

正With another wave of trade rows approaching,what’s the way out for Chinese solar makers?It seems Chinese solar exporters have hardly any time to catch a breath.Just when they think their business is going to bottom out following the settlement of a one-year trade dispute with their biggest export destination—the EU,yet another storm cloud is quietly gathering on the horizon.     

高职法学教育民事诉讼法学案例库建设的应用性研究

学科自身的特点决定了民事诉讼法学课程必须进行案例教学,而教育改革和司法改革的进行,以及高职法学教育适应社会多元化需求,培养应用型人才目标的确立,又使高职政法院校有必要建立适应需要的、具有应用性特色的、专门的高职民诉法学案例库,并对其应用性进行科学研究.对于集中表现为以"应用性"为特色的高职法学教育民事诉讼法学案例库的建设和完善,不能是一劳永逸,而应当是一项长期的、与时俱进的系统工程.     

A New Method for Determination of Postmortem Interval: Citrate Content of Bone*

Abstract: Few accurate methods exist currently to determine the time since death (postmortem interval, PMI) of skeletonized human remains found at crime scenes. Citrate is present as a constituent of living human and animal cortical bone at very uniform initial concentration (2.0 ± 0.1 wt %). In skeletal remains found in open landscape settings (whether buried or not), the concentration of citrate remains constant for a period of about 4 weeks, after which it decreases linearly as a function of log(time). The upper limit of the dating range is about 100 years. The precision of determination decreases slightly with age. The rate of decrease appears to be independent of temperature or rainfall but drops to zero for storage temperature <0°C.

Longevity Ancient and Modern

The article examines illustrations from ancient and modern societies to consider the connections between power, social elites and knowledge of techniques to promote longevity. In pre-modern societies, knowledge of practices and substances to promote longevity were cultivated by elites such as the Chinese imperial court. In modern societies, new technologies—cryonics, cloning, stem-cell applications and nanotechnology—will offer exclusive and expensive methods for prolonging life for the rich. However one important difference between the ancient and modern world is that with secularization longevity is no longer connected with a moral life; longevity is not a reward for sanctity. We have democratized the ambition for long life but not necessarily its realization. The modern quest for longevity appears to be connected with the desire of Baby Boomer generations to hold on to their assets, but while modern medicine may help us to survive forever, it cannot tell us how to live forever.

我国国有企业产权制度改革的思考

随着市场化改革的推进，我国政府加快了国有企业产权制度改革的步伐，越来越多的国有企业被纳入民营化的序列，产权结构多元化的格局基本形成，但从目前产权制度改革的实践来看，远未达到预期目的，国有企业产权制度改革要实现实质性突破，必须转变观念，从价值形态上认识存量资产的优势，借存量的调整和优化，实现资产由存量向增量的跨越，确保国有企业产权制度改革达到预期目的。     

Development of Latent Fingermarks on Surfaces of Food‐A More Realistic Approach

Latent fingermark developing methods from food (mandarin, egg, banana, apple, potato, carrot, eggplant, onion, bell pepper, and tomato) surface has been studied by 10 methods, including powdering method, small particle reagent method, and cyanoacrylate fuming method. The foods were stored under two conditions (room temperature and refrigerator) before fingermark deposition and aged for 2, 24, 48, and 72 h before fingermark development. In most of the food surfaces used in this study, cyanoacrylate fuming with 80% relative humidity was superior to the powder or small particle reagent methods. The quality of the fingermarks varied depending on the storage conditions before the fingermark deposition (in the refrigerator or at ambient temperature) and the time elapsed since the fingermark deposition. However, the storage conditions before the fingermark deposition and the time elapsed since the fingermark deposition did not show any correlation with the quality of the fingermark.     

Comparison of DNA yield after long-term storage of Second World War bone samples

Sample storage is of paramount importance in forensic genetics laboratories since only optimal storage enables successful recovery of DNA from old bones that contain very low amount of severely degraded DNA. When identification of missing persons from skeletal remains is completed, bone sample is routinely stored at -20 °C for long-term storage for retesting in future, if necessary. After molecular genetic analyses of Slovenian Second World War (WWII) victims, small fragments of femurs were stored at -20 °C. Reduction in DNA recovery has been observed in frozen liquid DNA extracts by some authors and the goal of our study was to explore how freezing of bone samples affects the preservation of DNA. To achieve this goal, the difference in DNA yield in extracts obtained from WWII bones analyzed in 2009 (data from published paper) and DNA yield in extracts obtained from the same bones (piece sampled next to the one used in 2009) taken out of the freezer after long-term storage on -20 °C for 10 years was examined, using the same extraction method and the same quantification kit. Up to 100 ng DNA/g of bone powder was obtained from 57 WWII femurs and up to 31 ng DNA/g of bone powder from the same femurs investigated after long-term storage in this study. 0,5 g of bone powder was decalcified using full demineralization extraction method. The DNA was purified in a Biorobot EZ1 device (Qiagen) and DNA quantity determined with the Human Quantifiler kit (TFS). Statistical analysis showed significant difference in DNA yield in extracts obtained from WWII bones in 2009 and extracts obtained from the same bones stored at -20 °C after 10 years. As reported for frozen liquid DNA extracts, reduction in recovery of DNA was confirmed for frozen bone samples as well.     

Stable isotope analysis of human hair and nail samples: the effects of storage on samples

When submitting samples for analysis, maintaining sample integrity is essential. Appropriate packaging must be used to prevent damage, contamination or loss of sample. This is particularly important for stable isotope analysis by isotope ratio mass spectrometry as this technique is capable of detecting subtle differences in isotopic composition with great precision. In a novel study, scalp hair and fingernail samples were placed in five different types of packaging, routinely used in forensic laboratories and stored for 6 weeks and 6 months. Samples were subsequently cleaned and submitted for (13)C/(12)C, (15)N/(14)N, (2)H/(1)H and (18)O/(16)O analysis. Results from (13)C analysis indicate that type of packaging can cause slight changes in (13)C abundance over time. Differences were noted in the (15)N isotope signatures of both hair and nail samples after 6-week storage, but not after 6 months. This apparent discrepancy could be a result of the packaging not being properly sealed in the 6 weeks study. Fewer differences were noted when analyzing samples for (2)H and (18)O abundance.
