论述了陆气相互作用研究在人类生存环境与发展区域经济中的重要意义与研究现状,在原有研究工作基础上,针对中国科学院红壤试验站地区陆气水热传输过程,提出了一个多层陆气耦合模式。对植被内部湍流交换的物理过程作了深入研究,特别考虑了叶片气孔为非饱和水汽条件下的交换情况,并且给出了修正后的根系吸水模式。陆气耦合模式分别对大气、植被、土壤作多层划分,以助于细致了解沿高度分布的各物理量。利用本模式对中国科学院红壤试验站地区油菜地陆气水热交换过程进行了数值模拟,模拟结果与实测值吻合较好。证明该模式成功地模拟了陆气相互作用过

Analisa o Projeto de Lei nº 6.002/1990 e apensos, que pretendem disciplinar o processo e julgamento do mandado de injunção individual e coletivo. A abordagem e o desenvolvimento da pesquisa serão realizados no contexto da judicialização da política ou do ativismo judicial, questionando-se qual será a efetividade dos limites/parâmetros impostos ao Supremo Tribunal Federal, acaso o Projeto de Lei nº 6.002/1990 e apensos, se transformem em norma jurídica. Tem-se como hipótese compreender se o pretenso disciplinamento limitará o ativismo judicial que retira o protagonismo do Poder Legislativo e o seu papel preponderante de poder legiferante. Os objetivos específicos da pesquisa são examinar a extensão e os efeitos das decisões do Supremo Tribunal Federal no julgamento de alguns mandados de injunção; avaliar se a conduta omissiva do Poder Legislativo causa prejuízos à sua própria imagem e se essa omissão inviabiliza o exercício de direitos, liberdades e prerrogativas constitucionais. A metodologia do trabalho será balizada na análise sistemática dos Mandados de Injunção números 107/1989-DF, 631/2000-MS, 670/2002-ES, 708/2004-DF, 712/2004-PA, 721/2005- DF, 758/2007-DF, 786/2007-DF e 795/2007-DF; na análise do Projeto de Lei nº 6.002/1990 e apensos; na Constituição Federal. O trabalho terá como principais referenciais teóricos e conceituais fontes e bibliografia apropriadas, a exemplo dos doutrinadores Alexandre de Moraes, Cândido Rangel Dinamarco, José Afonso da Silva, José Joaquim Gomes Canotilho,Luís Roberto Barroso e Manoel Gonçalves Ferreira Filho.

Background: Colorectal cancer (CRC) is a disease of complex aetiology, with much of the expected inherited risk being due to several common low risk variants. Genome-Wide Association Studies (GWAS) have identified 20 CRC risk variants. Nevertheless, these have only been able to explain part of the missing heritability. Moreover, these signals have only been inspected in populations of Northern European origin. Results: Thus, we followed the same approach in a Spanish cohort of 881 cases and 667 controls. Sixty-four variants at 24 loci were found to be associated with CRC at p-values <10-5. We therefore evaluated the 24 loci in another Spanish replication cohort (1481 cases and 1850 controls). Two of these SNPs, rs12080929 at 1p33 (P-replication=0.042; P-pooled=5.523x10(-03); OR (CI95%)=0.866(0.782-0.959)) and rs11987193 at 8p12 (P-replication=0.039; P-pooled=6.985x10(-5); OR (CI95%)=0.786(0.705-0.878)) were replicated in the second Phase, although they did not reach genome-wide statistical significance. Conclusions: We have performed the first CRC GWAS in a Southern European population and by these means we were able to identify two new susceptibility variants at 1p33 and 8p12 loci. These two SNPs are located near the SLC5A9 and DUSP4 loci, respectively, which could be good functional candidates for the association signals. We therefore believe that these two markers constitute good candidates for CRC susceptibility loci and should be further evaluated in other larger datasets. Moreover, we highlight that were these two SNPs true susceptibility variants, they would constitute a decrease in the CRC missing heritability fraction.

基于双折射波片的特性,提出了一种具有双调节模式的连续可调超分辨光瞳滤波器。该滤波器通过两种调节模式实现超分辨,且在一定范围内连续可调。在横向旋转模式下,该滤波器为复振幅型光瞳滤波器,纵向倾斜模式下为纯相位型超分辨滤波器。通过对超分辨参量的分析,得到最佳设计参量,可以实现大的视场角,大的超分辨范围、高的调节精度。这种滤波器为实际应用提供了更多的方便。

Fossil remains of reindeer (Rangifer tarandus) occurring outside their present range are an important indicator of formerly cold climatic conditions, but are easily confused with those of the red deer (Cervus elaphus). The locality of Kiputz IX has yielded one of the best-preserved Late Pleistocene reindeer populations of the southern Pyrenees, occurring in association with Bison priscus and the much more abundant Cervus elaphus. Fossil remains from this site are mostly complete and not affected by human intervention, thus creating the perfect conditions for reliable osteometric analyses. Here, we quantify diagnostic morphological features of the scapula and the humerus of Cervus elaphus and Rangifer tarandus to establish the potential of these bones to aid in interspecific discrimination. In the case of the scapula, the best species discriminator is the ratio of the minimum anteroposterior diameter of the scapular neck and the development of the articular process, while the breadth of the trochlea is the best discriminator in the case of the humerus.

Purpose Encouraging office workers to 'sit less and move more' encompasses two public health priorities. However, there is little evidence on the effectiveness of workplace interventions for reducing sitting, even less about the longer term effects of such interventions and still less on dual-focused interventions. This study assessed the short and mid-term impacts of a workplace web-based intervention (Walk@WorkSpain, W@WS; 2010-11) on self-reported sitting time, step counts and physical risk factors (waist circumference, BMI, blood pressure) for chronic disease. Methods Employees at six Spanish university campuses (n=264; 42 +/- 10 years; 171 female) were randomly assigned by worksite and campus to an Intervention (used W@WS; n=129; 87 female) or a Comparison group (maintained normal behavior; n=135; 84 female). This phased, 19-week program aimed to decrease occupational sitting time through increased incidental movement and short walks. A linear mixed model assessed changes in outcome measures between the baseline, ramping (8 weeks), maintenance (11 weeks) and follow-up (two months) phases for Intervention versus Comparison groups. Results A significant 2 (group) x 2 (program phases) interaction was found for self-reported occupational sitting (F[3]=7.97, p=0.046), daily step counts (F[3]=15.68, p=0.0013) and waist circumference (F[3]=11.67, p=0.0086). The Intervention group decreased minutes of daily occupational sitting while also increasing step counts from baseline (446 +/- 126; 8,862 +/- 2,475) through ramping (+425 +/- 120; 9,345 +/- 2,435), maintenance (+422 +/- 123; 9,638 +/- 3,131) and follow-up (+414 +/- 129; 9,786 +/- 3,205). In the Comparison group, compared to baseline (404 +/- 106), sitting time remained unchanged through ramping and maintenance, but decreased at follow-up (-388 +/- 120), while step counts diminished across all phases. The Intervention group significantly reduced waist circumference by 2.1cms from baseline to follow-up while the Comparison group reduced waist circumference by 1.3cms over the same period. Conclusions W@WSis a feasible and effective evidence-based intervention that can be successfully deployed with sedentary employees to elicit sustained changes on "sitting less and moving more".
