Though silanization of aluminum powder is currently used to improve its flow properties,for use as an alternative fuel source,there are a wide range of experimental parameters for the process and not all of them have been thoroughly *** this is complete,it is unknown if the process is optimized in terms of time,efficiency,and ***,we report on a study into the effects of changes in humidity,degree of agitation,reaction temperature,and curing time upon the deposition of phenyl triethoxysilane into 20μm(d50)aluminum *** confirm the deposition of the coating via diffuse reflectance infrared spectroscopy and x-ray photoelectron *** then characterize the coated particles using apparent density measurements and Carney flow *** analysis of variance,we find that,of the parameters explored,only changes in cure time and reaction temperature provide meaningful changes to the apparent density,while none of our parameters produced statistically significant changes in Carney flow ***,we conclude that,when optimizing silanization of aluminum particles,environmental control of humidity is unneeded and that the reaction can be run with minimal *** ability to largely ignore these parameters is a benefit to large-scale processing.

There are five vital signs that healthcare providers assess: temperature, pulse, respiration, blood pressure, and pain. Normal levels for the five vital signs are published by the American Heart Association, and other specialty organizations, however, the sixth vital sign (resilience) which adopts the measure of immune resilience is suggested in this paper. Resilience is the ability of the immune system to respond to attacks and defend effectively against infections and inflammatory stressors, and psychological resilience is the capacity to resist, adapt, recover, thrive, and grow from a challenge or a stressor. Individuals with better optimal immune resilience had better health outcomes than those with minimal immune resilience. The purpose of this paper is to conceptualize, contextualize, and operationalize all six vital signs. We suggest measuring resilience subjectively and objectively. Subjectively, use a 5-item guided interview revised from the Connor-Davidson Resilience Scale (CDRC), a scale of 10 items. The revised CDRC scale is a 5-item scale. The scale is rated on a 5-point Likert scale from 0 (not true) to 4 (true all the time). The total score ranges from 0 to 20, with higher total scores indicating greater resilience. The scale demonstrated good construct validity and internal consistency (α = 0.85) during the development of the scale. The CD-RISC had a good Cronbach’s alpha level of 0.85. The Revised CD-RISC can be completed in 2 - 4 minutes. To measure resilience objectively, we suggest using Immune Resilience (IR) levels, the level of resilience to preserve and/or rapidly restore immune resilience functions that promote disease resistance and control inflammation and other inflammatory stress. IR levels are gauged with two peripheral blood metrics that quantify the balance between CD8 and CD4 T-cell levels and gene expression signatures tracking longevity-associated immunocompetence and mortality- or entropy-associated inflammation.

A method based on regression modeling was developed to discern the contribution of component chemicals to the toxicity of highly complex, environmentally realistic mixtures of disinfection byproducts（DBPs）. Chemical disinfection of drinking water forms DBP *** of concerns about possible reproductive and developmental toxicity, a whole mixture（WM） of DBPs produced by chlorination of a water concentrate was administered as drinking water to Sprague–Dawley（S–D） rats in a multigenerational study. Age of puberty acquisition,i.e., preputial separation（PPS） and vaginal opening（VO）, was examined in male and female offspring, respectively. When compared to controls, a slight, but statistically significant delay in puberty acquisition was observed in females but not in males. WM-induced differences in the age at puberty acquisition were compared to those reported in S–D rats administered either a defined mixture（DM） of nine regulated DBPs or individual DBPs. Regression models were developed using individual animal data on age at PPS or VO from the DM study. Puberty acquisition data reported in the WM and individual DBP studies were then compared with the DM models. The delay in puberty acquisition observed in the WM-treated female rats could not be distinguished from delays predicted by the DM regression model, suggesting that the nine regulated DBPs in the DM might account for much of the delay observed in the WM. This method is applicable to mixtures of other types of chemicals and other endpoints.

近期的研究结果表明,利用地震P波最初几秒数据测量得到的平均"优势周期"τp,提供了对震级的快速近似估计,该方法能用于地震早期预警系统。尽管以往的研究说明了这种方法的经验价值,本文中我们仍将检测优势周期估计值的理论特性。我们指出,这种估计值是频谱振幅和周期的非线性函数,对大振幅和高频成分赋予了更大的权重。我们的结果还显示,通过递推关系计算得到的、与时间相关的τp最大值估计,在每次单独的测量中都存在固有的误差。在震级的优势周期估计中,尽管一些观测到的变化似乎是缘于局部场地效应,但本文结果表明,估计值的非理想特性也增加了结果的噪声。针对地震早期预警系统潜在的重要性,我们建议应对震级测定所依赖的初始P波数据的频谱特性进行更详细的分析,例如利用多锥形谱或小波方法,有助于设计更好的方法以实现系统性能的进一步优化。

Context Hemoglobin-based blood substitutes(HBBSs)are infusible oxygen- carrying liquids that have long shelf lives,have no need for refrigeration or cross- matching,and are ideal for treating hemorrhagic shock in remote *** trials of HBBSs during the last decade have reported increased risks without clinical benefit. Objective To assess the safety of HBBSs in surgical,stroke,and trauma patients. Data Sources PubMed,EMBASE,and Cochrane Library searches for articles using hemoglobin and blood substitutes from 1980 through March 25,2008;reviews of Food and Drug Administration(FDA)advisory committee meeting materials;and In- ternet searches for company press releases. Study Selection Randomized controlled trials including patients aged 19 years and older receiving HBBSs *** database searches yielded 70 trials of which 13 met these criteria;in addition,data from 2 other trials were reported in 2 press releases,and additional data were included in 1 relevant FDA review. Data Extraction Data on death and myocardial infarction(MI)as outcome variables. Results Sixteen trials involving 5 different products and 3711 patients in varied pa- tient populations were identified.A test for heterogeneity of the results of these trials was not significant for either mortality or MI(for both,I=0%,P(?)60),and data were combined using a fixed-effects ***,there was a statistically significant in- crease in the risk of death(164 deaths in the HBBS-treated groups and 123 deaths in the control groups;relative risk [RR],1.30;95% confidence interval [CI],1.05-1.61) and risk of MI(59 MIs in the HBBS-treated groups and 16 MIs in the control groups;RR,2.71;95% CI,1.67-4.40)with these *** analysis of these trials in- dicated the increased risk was not restricted to a particular HBBS or clinical indication. Conclusion Based on the available data,use of HBBSs is associated with a signifi- cantly increased risk of death and MI.

检验了用于地震重新定位和消除路径异常偏差的不同算子的性质。现有的3 种算法都是以下面的方法为基础:(1)jordan和Sverdrup(1981)的方法;(2)Got等人 (1994)的双差法;(3)Waldhauser和Ellsworth(2001)的改进的双差法。在本文中我们将说明虽然这3种算法在应用于实际时有明显不同,但是它们的数学本质却是相似的。我们的结果是在对每个方法的特性进行深入研究后得出的。无论是jordan和Sverdrup (1981)的方法还是双差法(Got et al,1994;Waldhauser and Ellsworth,2001)都在一系列的地震事件中消除了由于平均路径异常造成的定位偏差。但第一种方法中方程加权较理想。在Waldhauser和Ellsworth(2001)的改进的双差法中,与距离有关的加权在不采用阻尼的情况下并没有减少和地震位置相关的路径异常偏差,但是加阻尼会使空间上距离比较远的地震之间的定位问题得不到很好的解决。同样,jordan和Sverdrup (1981)和Got等(1994)也仅仅是将沿着模型子区的常量偏差消去而并没有解决子区之间的相对定位。这个研究的结果表明,在地震位置发生改变时由于速度不均匀性而造成的路径异常,各种算子由于自身缺陷都是无法克服的。在空间上离得很近的两个地震的情况可以通过相对定位来减少这种偏差的影响,但是当两个地震离得比较远的时候相对定位就不能减少这种影响。
