本发明一般与引信激励系统有关,尤其是与配有可变触发延迟定时器的引信激励系统有关。在设计触发作用的弹丸引信时,理想的是在目标内起爆弹丸。例如在飞机机内而不是一接触到目标就起爆弹丸。这可通过多种方法来实现。

Predictors of performance can aid coaches and trainers in prescribing exercise programs for rowing athletes. To date, most of the prediction models have been developed for runners and cyclists. Purpose: The aim of this study was to develop a regression model to predict performance of a simulated 2 kilometer rowing ergometer time trial. Methods: A group of mixed gender rowing athletes (n = 12) completed in a counterbalanced order a 2 kilometer rowing time trial and a continuous progressively incremented graded exercise test on a rowing ergometer. Subjects were 23.91 ± 4.99 years old, weighed 79.14 ± 12.85 kg, were 187.38 ± 12.60 cm, had a VO2max of 55.48 ± 10.32 mL/kg/min and had 3.17 ± 2.79 years of rowing experience. Physiological measures were recorded during both testing protocols. Results: Maximum power/stroke ratio (r =-0.96, p < 0.001), power/stroke ratio at the ventilatory breakpoint (r =-0.90, p < 0.001), maximal oxygen uptake (r =-0.84, p < 0.001) and oxygen uptake at the ventilatory breakpoint (r =-0.82, p < 0.001) were found to be strong and significant predictors of 2 kilometer rowing performance. Conclusion: The four significant predictors of rowing performance suggest training should focus on improving both aerobic capacity and strength. Practical Application: Rowing training should focus on developing hip and leg aerobic and anaerobic capacities to improve performance. Developing strength improves mechanical efficiency as well as raising anaerobic thresholds allowing athletes to utilize a larger portion of their aerobic capacity.

In high elevation semi-arid rangelands, sage- brush and other shrubs can affect transport and deposition of wind-blown snow, enabling the formation of snowdrifts. Datasets from three field experiments were used to investigate the scales of spatial variability of snow depth around big mountain sagebrush （Artemisia tridentata Nutt.） at a high elevation plateau rangeland in North Park, Colorado, during the winters of 2002, 2003, and 2008. Data were collected at multiple resolutions （0.05 to 25 m） and extents （2 to 1000 m）. Finer scale data were collected specifically for this study to examine the correlation between snow depth; sagebrush microtopogra- phy, the ground surface, and the snow surface, as well as the temporal consistency of snow depth patterns. Vario- grams were used to identify the spatial structure and the Moran＇s I statistic was used to determine the spatial correlation. Results show some temporal consistency in snow depth at several scales. Plot scale snow depth variability is partly a function of the nature of individual shrubs, as there is some correlation between the spatial structure of snow depth and sagebrush, as well as between the ground and snow depth. The optimal sampling resolution appears to be 25-cm, but over a large area, this would require a multitude of samples, and thus a random stratified approach is recommended with a fine measurement resolution of 5-cm.

Urokinase-type plasminogen activator （uPA） plays a crucial role in the regulation of plasminogen activation, tumor cell adhesion and migration. The inhibition of uPA activity is a promising mechanism for anti-cancer therapy. Most current uPA inhibitors employ a highly basic group （either amidine or guanidine group） to target the S1 pocket of uPA active site, which leads to poor oral bioavailability. Here we study the possibility of using less basic 2-aminobenzothiazole （abt） as S1 pocket binding group. We report the crystal structures of uPA complexes with abt or 2-amino-benzothiazole-6-carboxylic acid ethyl ester （abtCE）. The inhibitory constants of these two inhibitors were measured by a chromogenic competitive assay, and it was found that abtCE is a better inhibitor for uPA （Ki = 656 μM） than abt （Ki = 5.03 mM）. This work shows that 2-amniobenzothiazole can be used as P1 group which may have better oral bioavailability than the commonly used amidine or guanidine group. We also found the ethyl ester group occupies the characteristic oxyanion hole and contacts to uPA 37- and 60-loops. Such work provides structural information for further improvements of potency and selectivity of this new class of uPA inhibitor.

We report on XMM Newton guaranteed time observations of the Seyfert galaxy MCG 6 30 15. Confirming earlier results from ASCA, BeppoSAX , and RXTE, the fluorescent FeKα line in this source is found to be extremely broad. Modeling the line using a line emissivity I(r)∝r -β we find β>*** indicates that most line emission comes from the innermost regions around the central black hole. The emissivity coefficient is steeper than expected for standard models for the Fe Kα emission. This steep emission might be due to energy extraction from a rotating black hole.

阿拉伯地盾被一些地壳缝合线所切割,这些缝合线以超镁铁质岩带为标志,常代表着闭合的弧后盆地,或者直接是碰撞前锋的边界。但是,有关北阿拉伯地质构造方面的新资料表明,最长的缝合带即Nabitah断裂实际上是一个古老的弧间或近弧断裂,沿该断裂曾发生过较大的平移运动。图1说明了Nabitah造山带(1)、Murd(?)ma盆地(2)、abt片岩(3)和前寒武纪未分岩石(4)的出露区域,标明了Nabitah(N)、Yanbu(Y)、AL Amar(A)和Bi'r Umq(B)这些缝合线的位置。Nabitah断裂主要出露于阿拉伯地盾的轴部,切断了Bi'r Umq缝合线,与Nabitah造山带走向一致,沿南北向可进行追索。
