High power broad area semiconductor lasers have found increasing applications in pumping of solid state laser systems and fiber amplifiers, frequency doubling, medical systems and material processing. Packaging including the assembly design, process and thermal management, has a significant impact on the optical performance and reliability of a high power broad area laser. In this paper, we introduce the package structures and assembling process of 980nm broad area lasers and report the performances including output power, thermal behavior and far *** will report two types of high power broad area laser assemblies. One is a microchannel liquid cooled assembly and the other is a conduction cooled CT-mount assembly .Optical powers of 15W and 10W were achieved from a 980nm broad area laser with a 120μm stripe width in a microchannel liquid cooled assembly and conduction cooled CT-mount assembly, respectively .Furthermore, a high power of 6.5 W out of fiber was demonstrated from a pigtailed, fully packaged butterfly-type module without TEC ( Thermoelectric cooler ).The measurement results showed that thermal management is the key in not only improving output power, but also significantly improving beam divergence and far field distribution. The results also showed that the die attach solder can significant impact the reliability of high power broad area lasers and that indium solder is not suitable for high power laser applications due to electromigration at high current densities and high temperatures.

Dietary polyphenols, or phenolic compounds, are numerous, diverse, and ubiquitous phytochemicals occurring throughout the plant kingdom. They are important components of the human diet because of their capacity to reduce the risk of chronic diseases such as cardiovascular disease and cancer. In plants, polyphenols contribute to resistance to pathogens due to their potent astringency and function as phytoalexins. As a result, organic grapevines grown with reduced pesticides may be more stressed by pathogens than conventionally grown grapevines and presumably produce more polyphenols. Since polyphenols also play an important role in the sensory qualities of fruits and wines particularly involving astringency and bitterness, there may be differences that affect sensory perceptions of wine. This establishes a conundrum where dietary polyphenols are healthful but potentially *** recruited and randomized 18 female participants (21 - 50 y) to one of five groups (3 - 4 per group). Each group evaluated the sensory qualities of a geographically paired organic (OW) and conventional wine (CW) and an artificially colored white wine placebo (PW) with significantly differing total polyphenol concentrations (TP). Participants reported for three visits (one wine per visit) where they consumed 5 ounces (150 mL) of wine over 15 minutes while completing the sensory survey. Sensory evaluations based on a Likert-type scale included visual, aroma, and taste perceptions and overall impressions (scale 0 - 10). In two wine pairs, the OW contained significantly more TP (3.49 and 5.86 g/L) than the respective CW (2.63 and 4.63 g/L). In two other wine pairs both produced by sustainable viticulture, the CW (5.23 and 8.38 g/L) contained sig- nificantly more TP than OW (4.55 and 3.70 g/L) and in one set the amounts were equivalent (4.10 and 4.17 g/L). The five PW averaged 1.26 ± 0.20 g/L. Although there were significant differences in TP content of test wines, the results indicated that

In modern society, novel marine resources are scrutinized pursuing compounds of use in the medical, pharmaceutical, biotech, food or feed industry. Few of the numerous marine macroalgae are currently exploited. In this study, the contents of nutritional compounds from nine common North Atlantic red macroalgae were compared: the lipid content was low and constant among the species, whereas the fatty acid profiles indicated that these species constitute interesting sources of polyunsaturated fatty acids (PUFA). The dominating essential and non-essential amino acids were lysine and leucine, aspartic acid, glutamic acid, and arginine, respectively. The amino acid score of the nine algae varied from 44% to 92%, the most commonly first limiting amino acid being histidine. Lutein, β-carotene, and zeaxanthin were the identified carotenoids. Contents of all macro and trace minerals, with the exception of phosphorus, were higher than those described for conventional food. Low sodium/potassium ratios (0.08 - 2.54) suggested a potential for using the ash fraction for sodium salt replacement. The algae constituted rich sources of carbohydrates (40% to 71% of DM) which show their potential for a broader commercial exploitation. In some species, the concentrations of arsenic, cadmium, and lead exceeded limit values for application in food or feed. In conclusion, the nine algae represent promising potential sources of health promoting additives for human and animal diets, in whole or in a biorefinery concept.

研究目的研究青春晚期超重和吸烟影响成年后病死率的联合效应。研究设计用经过肌力、社会经济地位、年龄等因素校正的Cox比例风险模型进行连锁分析。研究地点瑞典军队征兵登记，死亡原因登记和普查数据。研究对象45920名瑞典人（平均年龄18．7岁，标准差为0．5），随访38年。主要观察指标体重指数（Body mass index，BMI）（低体重（BMI〈18．5），正常体重（18．5～24．9），超重（25～29．9），肥胖（≥30））；肌力，在1969-1970年间军队征兵的强制性测试中自报的吸烟状况（不吸烟者，轻度吸烟者（1～10支／天），重度吸烟者（〉10支／天）；全因死亡。结果在170万人年中，有2897人死亡。与正常体重的人群（病死率为17／10000，95％可信区间为16～18）相比，超重（风险比为1．33，1．15～1．53；病死率为23，20～26）和肥胖（风险比为2．14，1．61-2．85；病死率为38，27～48）的人群死亡的风险增高，同样，对吸烟者与非吸烟者的分析也得出类似的结论。尽管消瘦（BMI〈17）被认为与病死率增加有关（风险比为1．33，1．07～1．64；病死率为24，19～29），并没有发现低体重的人群中死亡风险增加（风险比为0．97，0．86～1．08；病死率为18，16～19）。源于体重指数和吸烟状况联合效应增加的相对危险度在任何一组人群中并不显著。同时，除了肥胖和重度吸烟（增加的相对危险度1．5，-1．7～3．7）以外，其他任何组合的联合效应与其单独存在时相比，差异均无统计学意义。与不吸烟者（病死率为14，13～15）相比，轻度（风险比为1．54，1．41—1．70；病死率为15，14～16）和重度（风险比为2．11，1．92—2．31；病死率为26，24—27）吸烟者的死亡风险均有所增加。结论无论吸烟状况如何，在青春晚期超重和肥胖均可致成年后的病死率增加。肥胖、超重的危害分别与重度吸烟、轻度吸烟相当，但是，体重指数和吸烟情况并没有交互影响。青少年中全球性的肥胖流行和吸烟仍然是促进公共卫生健康必须关注和解决的问题。
