The study illustrates the critical role of accurate geological structural mapping to delineate crystalline aquifer zones more prone to high health risk due to elevated dissolved As in drinking *** analysis revisits the results from more than 1200 groundwater samples collected over ten years from domestic wells across the Tampere region (Finland).It is demonstrated that the highest dissolved As concentrations in the region (up to 2230 mg/L) are exclusively found near major faults and deformation zones (FDZs) detected via geophysical and geological surveys,and that a clear correlation exists between dissolved concentrations and the distance from the FDZs (r).Almost all values exceeding the drinking water limit (10 mg/L) occur at r < 8 km,while concentrations above 100 mg/L occur at r < 4 *** As concentrations in bedrock show less dependency on FDZ than aqueous *** behavior is explained considering different mechanisms,which include enhanced sulfide oxidation and fracture connectivity,promoting preferential transport of dissolved As to FDZs and mixing of waters from different redox zones,mobilizing preferentially As(III) or As(V).Fe hydro-oxides may also precipitate/ dissolve preferentially because of FDZs,while residence time may influence the contact time between water and As-bearing *** is concluded that the accurate mapping of FDZs,and in general of structural geology,provides an important preliminary information to identify where localized,sitespecific characterization of hydrogeology and geochemistry is more urgent to reduce As-related health risk from groundwater intake.

Non-Markovian discrete qubit dynamics

Science Bulletin 2016年第13期61卷 1031-1036页

The study of open quantum systems is important for fundamental issues of quantum physics as well as for technological applications such as quantum information processing. The interaction of a quantum system with its environment is usually detrimental for the quantum properties of the system and leads to decoherence. However,sometimes a quantum control can lead to a coherent partial exchange of information between the system and the dynamics of the open system might become non-Markovian. In this article, we study experimentally discrete nonMarkovian open quantum system dynamics. We implement a local control protocol using linear optics for controlling the information flow between the open system and the environment. We show how the transition from Markovian to non-Markovian dynamics can be controlled using only local operations for the open system.

Using Individual, ApoE Genotype-Based Dietary and Physical Activity Advice to Promote Healthy Lifestyles in Finland—Impacts on Cardiovascular Risk Markers

引用

Open Journal of Preventive Medicine 2015年第5期5卷 206-217页

作者： Hanna-Leena Hietaranta-luoma Kari Akerman Raija Tahvonen Hannu Puolijoki Anu Hopia Functional Foods Forum University of TurkuTurkuFinland Central Hospital of Southern Ostrobothnia SeinajokiFinland Natural Resource Institute Finland(Luke) Earlier MTT Agrifood Research FinlandJokioinenFinland

Aim: There is increasing demand for individualized health advice. The aim of this study was to assess the effects on cardiovascular risk markers of receiving personal genetic health information, using apoE genotypes as a tool for promoting lifestyle changes. ApoE was chosen because it had a significant impact on lipid metabolism and cholesterol absorption, all factors for CVD. Methods: This study was a one-year explanatory intervention study for healthy adults, aged between 20 - 67 years old (n = 106). Their clinical markers (serum lipids, blood glucose, blood pressure, Body Mass Index, body fat percentage and waist circumference) were measured three times during the intervention. The clinical effects were assessed for three groups: a high risk group (ε 4+, n = 16);a low-risk group (ε?4-, n = 35);and a control group (n = 55). Results: The triglyceride values and waist circumference lowered more in ε?4+ compared with the control group (p < 0.05;alpha value 0.005) during the intervention. Conclusion: The personal genetic information, based on apoE, may have positive effects on cardiovascular risk markers (e.g., improvement in triglyceride values). The individual health information, based on genotyping could be a potential option in the prevention of CVD. More research is required on how to utilize genotype-based health information in the prevention of lifestyle-related diseases.

外生菌根的地下子实体采自代表花旗松的一系列典型自然生境的10个样地中。对所有样方的计算表明，总干物质生物量是1．3kg／ha，单个样方的最大生物量是9．9kg／ha。记录了47种地下生真菌；有14种共占总生物量的94％。颗粒大团囊菌（Elaphomycesgranulatus），高山腹菌（Gautieriamonticolar），革质辐片包（Hysterangiumcoriaceum），变红白腹菌（Leucogasterrubesceus）和公园须腹菌（Rhizopgonparksii）5个种占生物量的73％。与研究区域内的地上真菌相比较，地下真菌的子实体生产量春季比秋季高，生境分为5个类型（WOG湿润过熟林，MOG中湿过熟林；DOG干旱过熟林；MM中湿成年林；MY中湿幼年林）；形成两个梯度：湿润──干旱和幼林──过熟林。MM生境的生物量最大（2．2kg／ha），DOG生境最小（0．7kg／ha）。个别的种表现出强烈的季节性变化，大多数种有春或夏季的生长峰。有些种子实体产生也因生境不同而有差异，例如，Leucogasterrubescons的生长高峰出现在DOG生境，而Leucophlepsmagnata的生长高峰出现在非过熟林生境上，相比之下，Rhizopegonrincicolor在所有生境中都有分布。对样地分布范围的分析表明，样地面积小（≤800m^2）会导致过高估计子实体产量，因为生物量与高估值十分不一致。另外，?

天鹅，古称“鹄（hú）”，“燕雀安知鸿鹄之志哉!”比喻英雄壮志。它高贵优雅，矫健机警，在大多数情况下，很难接近一睹芳容。可是在山东荣成国家级天鹅自然保护区，人们爱护天鹅，亲近天鹅，因此每年都有上千只天鹅从11月初到次年3月中到这里越冬。用广角镜就能拍天鹅已经不再是神话。当然，任何镜头在这里都有用武之地。威海市烟墩角不仅可以亲密接触天鹅，海湾日出、日落，惊涛拍岸，可以找到很不错的题材。
