Sea-ice algae are a par.m.unt feature of polar.m.rine ecosystems and ice algal standing stocks are characterized by a high spatio-temporal variability. Traditional sampling techniques, e.g., ice coring, are laborintensive, spatially limited and invasive, thereby limiting our understanding of ice algal biomass variability patterns. Thishas consequences for quantifying ice-associated algal biomass distribution, pr.m.ry production, and detecting responses to changing environmental conditions. Close-range under-ice optical r.m.te sensing techniques have emerged as a capable alternative providing non-invasive estimates of ice algal biomass and its spatial variability. In this review we first summarize observational studies, using both classical and new methods that aim to capture biomass variability at multiple spatial scales and identify the environmental drivers. We introduce the complex multi-disciplinary nature of under-ice spectral radiation profiling techniquesand discuss relevant concepts of sea-ice radiative transfer and bio-optics. In addition, we tabulate and discuss advances and limitations of different statistical approaches used to correlate biomass and under-ice light spectral composition. We also explore theoretical and technical aspects of using Unmanned Underwater Vehicles （UUV）, and Hyperspectral Imaging （HI） technology in an under-ice r.m.te sensing context. The review concludes with an outlook and way forward to combine platforms and optical sensors to quantify ice algal spatial variability and establish relationships with its environmental drivers.

Objective: We explored the impact of increasing number of off-label patient and lesion character-istics on 5-year clinical outcome following implantation of first generation drug eluting stents. Furthermore we tried to assess if stent performance might be improved if the off-label character-istics present were taken into account to guide the stent brand selection. Design: A total of 2888 coronary lesions treated with first generation drug eluting stents were classified for eventual presence of 18 different off-label characteristics and correlated to the 5-year clinical outcome by multiple stepwise Cox regression analysis. results: The composite of cardiac death, myocardial infarction and target vessel revascularization (major adverse cardiac event, mACE) was 16.7% in cases with zero off-label characteristics and showed a stepwise increased rate up to 32.7% in cases with 5 off-label characteristics. The mACE rate for the sirolimus eluting stent appears to be 10% lower than the paclitaxel stent group and it may be further reduced by 10% - 18% if the off-label characteristics present in each case were taken into account to guide the stent brand selection. Conclusion: With increasing number of concomitantly appearing off-label characteristics there is a stepwise increase in mACE rate. The mACE rate may be reduced if the off-label characteristics were used to guide the stent brand selection.

Background: Built environments that are designed to provide accessible, attractive, and convenient locales pr.m.te regular physical activity(PA).Norway has great variability in its geographic, natural, and built environment features. Urban areas have well-developed built environment features, whereas the rural areas are less walkable and this may influence the mode of transport. In general, active transport is more common in urban centers. Further, public transportation is more developed in urban areas, whereas motorized transport may be more widespread in the rural areas. Despite this, in Sogn & Fjordane, a rural county in western Norway, high PA levels are frequently observed. Thus, the aims of this study were to(1) explore perceived built environment features and characterize their associations with objectively measured PA levels in Norwegian adults and(2) explore the differences in these correlates between Sogn & Fjordane and the rest of ***: In this cross-sectional study, participants used questionnaires to rate perceptions of their built environments, and their PA was objectively measured for 7 consecutive days using the Acti Graph GT1 m acceler.m.ter. There were 972 Norwegian adults who were included in the study. The average age was 46.9 ± 6.5 years and 43.8% of participants were men. Data were analyzed using multiple linear ***: Total PA and moderate-to-vigorous physical activity(mVPA) were both associated with perceived walkability, the community perception score, and active transport for commuting(all p ≤ 0.004). We also observed geographic-area-specific associations: the community perception score was negatively associated with total PA and mVPA in the rest of Norway(p ≤ 0.012) but not in Sogn & Fjordane. Public transport for commuting was positively associated with mVPA in Sogn & Fjordane(p = 0.03) but not in the rest of ***: Total PA level and mVPA were associated with built environment factors, such as perceptio

The Kushiyara and monu rivers are two of the major river systems in the northeast region of Bangladesh. Analyzing satellite images of the Kushiyara and monu rivers between 1990 and 1997, it was found that significant changes occurred at five distinct locations; i.e., Ahmadpur, monumukh, raysrr, Kaprangibari and Telibil. The amount of change was measured as 168.34 ha by using a plani-meter. Transportation of sediment was the major contributing factor of morphological change. The total average sediment concentration of Kushiyara and monu rivers was found to be 16889.6 ppm per year during the study period by applying the Engelund and hansen equation approach. Protection work has been suggested at the vulnerable locations.

针对U型钢板桩插打容易发生屈曲的问题,提出U型钢板桩局部加劲效应理论计算的“动态配位系数法”,建立了局部加劲U型钢板桩失稳临界荷载计算式,并分析了加劲面积、加劲位置、加劲板数量对加劲效应(即失稳临界荷载)的影响规律.研究结果表明:加劲总面积(即加劲板累计宽度)一定时,对于长度确定的U型钢板桩,存在使构件临界荷载值最大化的加劲板布置方案,并揭示了块数太多时由于单块加劲板宽度太小而引起的局部失稳规律;以10 m长U型钢板桩为例,构件临界荷载值随单块加劲板布置位置的变化可提高13.55%,并求得20 m长的U型钢板桩不同加劲总面积对应的加劲板布置优化理论方案,为实际工程中U型板桩局部加劲方案设计提供了理论依据和参考.

随着生活方式和食物成分的改变,发达国家乃至全球的肥胖的患病率日益增加.在美国,20岁以上的人群中,肥胖的患病率大约为33%.在儿童和青少年中,肥胖在过去的20年中已增加了50%,估计其患病率至少为25%.遗传学在肥胖的发生中起重要的作用,而进食摄入的增加及久坐的生活方式对肥胖的作用也不容忽视.儿童期肥胖导致的主要并发症和危险因素包括心理社会障碍、高血压、高脂血症、呼吸功能障碍和糖尿病(Dm).当体重指数(BmI)＞27kg/m2时,发生这些并发症的危险性明显增加,其中最可能发生的是2型Dm.最近有报道,儿童新诊断的Dm中8%～45%为2型Dm.不只在北美青少年2型Dm的发病率是增加的.日本学校的儿童从1976～1995年,每10万名儿童2型Dm的发病率从0.2/10万增加到了7.3/10万,其中13～15岁的人群中,每10万名青少年2型Dm的发病率为13.9/10万.如同北美一样,日本的经验也反映了食物结构的变化及肥胖患病率的增加,因此对大多数医生和保健人员来讲如何评价和处理儿童或青少年2型Dm是一种新的挑战.一、临床估价家族史对儿童肥胖的发病提供重要的线索.肥胖儿童的父母通常也是超重的,如果父母双方均肥胖,其子女80%肥胖;如果父母双方有一方肥胖,其子女则40%肥胖.种族背景也应考虑,另外,还应收集有关膳食结构家庭饮食及看电视与运动习惯等生活方式的资料.查体时应准确地测量身高体重和血压,并注意患者的脂肪分布情况及是否伴随黑棘皮症,因黑棘皮症是高胰岛素血症和胰岛素抵抗的表现.雄激素增多所致的痤疮和毳毛增多也与胰岛素抵抗相关.

研究气温突变前后栓皮栎(Quercus variabilis Blume)径向生长海拔差异及其气候响应的变化,可为不同海拔栓皮栎林的养护管理提供参考数据.基于太行山南麓海拔1507 m和909 m的栓皮栎样地年轮宽度数据,结合树轮序列的差值年表(rES)与气候因子分析两个海拔栓皮栎径向生长在气温突变前后对气候响应的差异,并利用胸高断面积年增长量(BAI)分析两海拔栓皮栎生长速度的差异.结果显示,高海拔栓皮栎的BAI年增长速度[0.63 cm^(2)/(10 a)]高于低海拔[0.23 cm^(2)/(10 a)],且在温度上升作用下二者差值逐渐增大.在具有明显快速升温变化(1992年)之前,高海拔栓皮栎生长主要与当年2、7月温度显著正相关,低海拔栓皮栎生长则主要与夏季(6-8月)降水呈正相关.快速升温变化之后,高海拔栓皮栎生长与当年7月平均与最低温度由正相关转变为负相关;低海拔栓皮栎生长与当年3月最高温度和7月最低温度由正相关转变为负相关.本研究表明温度升高使两海拔栓皮栎径向生长-气候因子关系发生了改变,温度对树木生长的限制作用增强,升温促使研究区内高海拔相对低海拔区域成为栓皮栎的适生区.(图7表3参38)
