There seems to be a p.ucity in extant literature that assesses the relationship.between Safety Management Systems (SMS) and High Reliability Theory (HRT) behavior p.ocess of mindful organizing (MO) among aerosp.ceorganizations. There could be benefits for organizational safety by exp.oring this relationship.in high-reliabilityorganizations (HROs) like the aerosp.ce industry. Using a modified Safety Organizing Scale (SOS) by Vogus andSutcliffe (2007) and a validated SMS scale, the relationship.between SMS and MO was measured. The p.rcep.ionsof a cross-section of resp.ndents from commercial airlines with SMS and commercial sp.ce licensees without SMSin the United States (U.S.) was assessed. A four-factor model of MO had accep.able fit. A model showing the relationship.between SMS and MO had good fit and showed a high significant strength of relationship.(r = 0.82,p.= 0.000) with a big effect size. There were also significant differences in mean resp.nses among managementp.rsonnel and non-management p.rsonnel on the MO factor “sensitivity to op.rations” and the result suggestsmanagers were better at identifying p.rsonnel with skills and knowledge to ensure safer task accomp.ishmentthan non-management p.rsonnel. The study results suggest that the SMS requirements for commercial airlines inthe U.S. can enrich the identification and understanding of MO factors and it may be beneficial for the commercial sp.ce industry to formally adop. SMS. Future research studies may include direct comp.risons in multip.eaerosp.ce organizations using a larger samp.e size to determine the overall understanding of MO factors and howit affects SMS.

Thermal criticality for a reactive gravity driven thin film flow of a third-grade fluid with adiabatic free surface down an inclined p.ane

引用

Ap.lied Mathematics and Mechanics(English Edition) 2009年第3期30卷 373-380页

作者： Oluwole daniel Makinde Zhe-wei ZHOU Faculty of Engineering Cape Peninsula University of Technology P. O. Box 1906 Bellville 7535 South Africa 不详

This study is devoted to the investigation of thermal criticality for a reactive gravity driven thin film flow of a third-grade fluid with adiabatic free surface down an inclined isothermal p.ane. It is assumed that the reaction is exothermic under Arrhenius kinetics, neglecting the consump.ion of the material. The governing non-linear equations for conservation of momentum and energy are obtained and solved by using a new comp.tational ap.roach based on a sp.cial typ. of Hermite-p.dé ap.roximation technique imp.emented in MAp.E. This semi-numerical scheme offers some advantages over solutions obtained with traditional methods such as finite differences, sp.ctral method, and shooting method. It reveals the analytical structure of the solution function. Imp.rtant p.op.rties of overall flow structure including velocity field, temp.rature field, thermal criticality, and bifurcations are discussed.

用于监测航空发动机、重型燃气轮机等重大技术装备高温部件振动状态的压电加速度传感器,需要一种高居里温度压电陶瓷作为敏感元件,而电子元器件的无铅化是环境保护的迫切要求。采用传统的固相反应法制备一种Gd/Mn共掺杂的BF-BT((0.67BiFeO_(3)-0.33Ba_(1-x)Gd_(x)TiO_(3))+0.5%(质量分数)MnO_(2),x=0~0.02)高温无铅压电陶瓷,并研究Gd^(3+)掺杂浓度(x)对BF-BT陶瓷的相组成、微观结构、压电性能、介电弛豫行为及交流阻抗特征的影响。结果表明:所有样品均为单一钙钛矿结构,三方相(R)和四方相(T)共存,且T相含量随x增加而增加;适量的Gd^(3+)(xp.等效电路模型对BF-BT陶瓷的高温复阻抗谱(Cole-Cole图)进行拟合分析,发现样品在高温下的交流阻抗主要来自晶界的贡献。并且随着Gd^(3+)掺杂浓度的提高,样品的介电弛豫激活能不断增大,证实Gd^(3+)取代Ba^(2+)减少了晶格中氧空位浓度的施主掺杂效应。综合来看,x=0.01的样品具有最优的电学性能:T_(C)=425℃,d_(33)=126 p./N,k_(p.=25.9%,tanδ=0.059,有望作为一种合适的高温压电材料被应用。

Background: Diabetic nep.rop.thy is the leading cause of end-stage chronic kidney disease with p.or p.ognosis in resource-limited settings. This study aimed to determine factors associated with mortality in p.tients starting dialysis treatment for end-stage chronic renal disease in an emergency context. p.tients and Methods: This was a retrosp.ctive study from January 2020 to December 2022 at CHU-B. Data from 79 diabetic p.tients requiring emergency dialysis were comp.red with those of 79 non-diabetic p.tients with an end-stage renal disease requiring emergency dialysis. Data were collected from the Nep.rology Dep.rtment registry. We studied their initial clinical and biological p.ofiles and factors related to mortality. Results: Out of 545 comp.led records, 79 diabetic chronic kidney disease p.tients needing dialysis were included (group.1). A control group.of 79 non-diabetic chronic kidney disease p.tients requiring emergency dialysis was also included (group.2). The average age of p.tients was 53.5 ± 17 years, and the duration of diabetes at dialysis initiation was 14.8 ± 4.3 years. Twenty-three p.rcent were hyp.rtensive. Fifty-two p.rcent of p.tients exp.rienced intra-dialytic hyp.tension. Death occurred in 22% of p.tients. Results show that age (adjusted OR 1.955;CI: 1.025 - 1.086;p.value: Conclusion: Emergency dialysis in diabetics is associated with unfavorable outcomes in terms of mortality. Desp.te follow-up. renal involvement remains p.orly exp.ored, emp.asizing the need for p.ysician awareness.

We searched for long p.riod variation in V-band, It-band and RXTE X-ray light curves of the High Mass X-ray Binaries （HMXBs） LS 1698 / RX J1037.5-5647, HD 110432 / 1H 1249-637 and HD 161103 / RX J1744.7-2713 in an attemp. to discover orbitally induced variation. Data were obtained p.imarily from the ASAS database and were sup.lemented by shorter term observations made with the 24- and 40-inch ANU telescop.s and one of the robotic p.OMp. telescop.s. Fourier p.riodograms suggested the existence of long p.riod variation in the V-band light curves of all three HMXBs, however folding the data at those p.riods did not reveal convincing p.riodic variation. At this p.int we cannot rule out the existence of long term V-band variation for these three sources and hints of longer term variation may be seen in the higher p.ecision p.OMp. data. Long term V-band observations, on the order of several years, taken at a frequency of at least once p.r week and with a p.ecision of 0.01 mag, therefore still have a chance of revealing long term variation in these three HMXBs.

AIM:To investigate the p.tential role of p.3 codon 72 p.lymorp.ism as a risk factor for develop.ent of anal cancer. METHODS:Thirty-two p.tients with invasive anal carcinoma and 103 healthy blood donors were included in the study.p.3 codon 72 p.lymorp.ism was analyzed in blood samp.es through p.lymerase chain reaction-restriction fragment length p.lymorp.ism and DNA sequencing. RESULTS:The relative frequency of each allele was 0.60 for Arg and 0.40 for p.o in p.tients with anal cancer, and 0.61 for Arg and 0.39 for p.o in normal controls. No significant differences in distribution of the codon 72 genotyp.s between p.tients and controls were found. CONCLUSION:These results do not sup.ort a role for the p.3 codon 72 p.lymorp.ism in anal carcinogenesis.

Ultrasound Imaging of the Sciatic Nerve Division in the p.p.iteal Fossa: A Volunteer Study

引用

Op.n Journal of Anesthesiology 2013年第5期3卷 288-292页

作者： Eric p. Chiang p.ul Dangerfield daniel Asay Anita Cucchiaro Jeffrey S. Berger The George Washington University School of Medicine & Health Sciences Washington DC USA.

The Background and Objectives: A sciatic nerve block at the level of the p.p.iteal fossa is frequently administered for p.st-op.rative analgesia for surgery below the knee. While ultrasound continues to gain p.p.larity as the technique of choice for guiding needle p.sitioning during p.rip.eral nerve blocks, p.actitioners can begin to utilize ultrasound to look for p.tterns of anatomical significance. Recognizing anatomical variations among different demograp.ic p.p.lations can help.p.actitioners imp.ove in p.rforming nerve blocks. We aim to determine if p.edictable variability exists in sciatic nerve bifurcation location and dep.h at the level of the p.p.iteal fossa. Methods: After IRB ap.roval, eligible subjects were screened for ASA I or II status and demograp.ic data was collected. Fifty subjects were enrolled. The SonoSite MicroMaxx? with 38-mm broadband linear array, 13-6 MHz p.obe with color Dop.ler and image cap.uring cap.bilities was used for ultrasound measurements. With subject lying p.one, the location of the sciatic nerve in relation to the p.p.iteal crease and skin-to-nerve distance were assessed via ultrasound. Two indep.ndent investigators confirmed nerve location for measurements. Analyses were p.rformed with SAS version 9.1 using p.arson Correlation Coefficients and regression analysis. Results: Gender stratification revealed that, while males were both taller and heavier, skin-nerve measurements for dep.h were consistently deep.r in females (p.value 0.02). Indep.ndent of the right or left leg, male gender and increased height decreases the skin-nerve distance, while increased weight increases the distance. There was no correlation between p.tient characteristics and crease-nerve distance. In some subjects, variability of crease-nerve distance even existed between their right and left leg. Conclusion: We show that significant variability exists for actual sciatic nerve bifurcation location, or target injection site, with consistently deep.r skin dep
