术文描述由休斯航空公司研制、试验和取得专利的低重力推进剂测量系统(PGS)。PGS 在通常卫星预定15年飞行寿命中预测卫星寿命终了(EOL)的准确度在±2月之内甚至更佳。该系统已用于休斯 HS601同步通信卫星。PGS 从初始设计就简化并尽力减少系统所要求的硬件。现有的挤压气体箱和推进剂箱中间装有高分辨率传感器和内接阀门。PGS 通过瞬间打开对应的高压挤压气箱与推进剂箱之间的互连阀对推进剂周期性地加压进行测量。根据加压前后压力的测量值,应用气体定律计算可以确定推进剂箱中气体的体积,进一步可以得到液体的体积,这样就计算出箱中推进剂的质量。应用气体定律时也需要测定温度。为精确测定温度,每个贮箱都安装了多个温度敏感器,为进一步提高精度,使用非常精确的高分辨率的压力传感器作为气体温度计。通过对所推荐的测量方案的原型机试验,建立了对系统精确预测由于推进剂耗尽而引起的卫星寿命终了的能力的信心。PGS 具有容错能力,不受推进剂分系统正常工作的干扰。加压能力为双元推进系统额外提供了精密地控制氧化剂-燃料混合比的好处,这样通过使伴随某种推进剂比另一种先耗尽时使推进剂的残留量降到最低来提高位置保持寿命。

Objective. motor impairment after neonatal and childhoodonset ischemic stroke (IS) is common, although the prevalence and type of hemiparesis differs between the 2 age groups. Lesion topography is an important predictor of hemiparesis after neonatal IS, but it is not known if the same topographic predictors of adverse motor outcome apply to childhood-onset IS. We used a consistent approach to define lesion topography and evaluate motor outcome in both age groups to (1) investigate whether early topographic predictors of hemiparesis after unilateral middle cerebral artery-territory stroke are the same in neonates and older children and (2) compare the prevalence of dystonia and loss of independent finger movements between the 2 age groups. Design. Twenty-eight patients with neonatal-onset IS (Hammersmith Hospital, London,United Kingdom)were studied together with 43 patients with childhood-onset IS (Great Ormond Street Hospital, London, United Kingdom). All patients had exclusive unilateral middle cerebral artery-territory IS. Lesion topography was studied by using the first magnetic resonance image acquired after the onset of symptoms and was coded for involvement of cerebral cortex (CC), posterior limb of the internal capsule (PLIC), basal ganglia (BG), and white matter. The primary outcome was hemiparesis, and secondary outcomes were dystonia and loss of age-appropriate independent finger movements. Results. Hemiparesis was more common after childhood-onset IS (56%) than neonatalonset IS (24%). In neonatal-onset IS, concomitant involvement of BG, CC, and PLIC predicts the development of hemiparesis (odds ratio: 99; 95%confidence interval: 5.2-1883.8), and no child with 1 or 2 of these structures involved developed hemiparesis. In contrast, in childhood-onset IS, concomitant BG, CC, and PLIC lesions tended to be associated with hemiparesis (9 of 11), but this adverse outcome was seen also among patients with 1-or 2-site involvement. However, hemiparesis was less lik

Based on a series of newly developed bioactive glasses having suitable thermo-mechanical properties to allow application as fixation agents between bone and titanium alloy biomedical implants, the stress corrosion crack growth (SCCG) behavior of their interfaces with Ti6AI4v was investigated in simulated body fluid (SBF) with the objective of discerning the salient mechanisms of crack advance and to assess the reliability of the bonds. Results indicated that crack growth rates in Ti6AI4v/glass/Ti6AI4v sandwich specimens were nearly the same as or slightly lower than those in the bulk glasses at comparable stress intensities; indeed, cracks would prefer to propagate off the interface, suggesting that the Ti6AI4v/glass interface has relatively good crack-growth resistance. mechanistically, interfacial crack growth appears to be controlled by the classic stress corrosion mechanisms for silicate glasses, with no discernible effect of bioactivity on the SCCG behavior being observed.

The case of a 38- year-old woman with continuous unilateral side-locked headache is reported. She had continuous right-sided periorbital pain of mild to moderate intensity for the past 5 months. She also reported a few episodes of pain exacerbations every day. She had no autonomic features. Based on a normal CT scan ordered by her general physician, we started indomethacin (150 mg/day) as well as celecoxib (400 mg/day) for 2 weeks, without relief. Oral prednisone for 6 days provided important relief, and she stayed on daily use of steroids, refusing other forms of therapy. After 5 months she developed orbital and eyelid edema, with painful restrictions to eye movement. Orbital mRI and pathological exam demonstrated inflammatory orbital pseudotumor (myositic form).

本文利用THEmIS卫星结合地面极光和地磁的观测,研究了2008年2月26日04:05和04:55UT的两次亚暴事件.Angelopoulos已经对发生在04:55UT的第二个亚暴事件做了分析.本文对两次亚暴的相关活动进行了详细研究,特别对第一次做了深入讨论,并着重分析了磁重联与亚暴活动的关系.在两次亚暴的初始阶段,第一次极光增亮发生在中磁尾磁重联后2～3min,但是持续时间较短,极向膨胀缓慢,与伪暴的特征相似,标志了亚暴的初突发(initial onset).两次亚暴都存在第二次极光增亮和极光的极向膨胀,且时间与近地磁尾观测的地向流和磁场偶极化同时发生,并与亚暴膨胀相的其他活动的发生同步,标志了亚暴的主突发(major onset).在两次亚暴的增长相期间,极盖区开放磁通量持续增加;在亚暴膨胀相和恢复相中,极盖区磁通量迅速减少.表明两次亚暴膨胀相的演化分别与两次尾瓣开放磁力线重联过程相联系的.从亚暴活动的参数分析,这两次亚暴都属于小亚暴范围;从重联率分析,两次磁重联都属于弱重联.本文的观测结果表明,中磁尾磁尾重联首先触发伪暴;高速流将磁通量和能量传输到近地磁尾;高速流减速最终导致亚暴电流楔(substorm current wedge,简称SCW)的形成和电流中断,产生近地偶极化和极光膨胀,引起亚暴膨胀相突发.本文的观测结果是对近地中性线模型(near earth neutral line,简称NENL)和重联-电流中断协同模型(synthesis scenario of mR and CD,简称RCS)模型及亚暴膨胀相两步突发观点的有力支持.
