Open Journal.of Nursing 2022年第7期12卷 496-504页

作者： Amanda J. Fl.gg Sherri l. Stevens Joyce Finch Michel.e Finch Barbara lancaster Tabby Ragl.nd School.of Nursing Middle Tennessee State University Murfreesboro TN USA

The opportunity to offer immediate service to a l.cal.community in need of an additional.COVID Vaccine Cl.nic was wel.omed by the School.of Nursing (SON) at Middl. Tennessee State University (MTSU). This opportunity not onl. opened a door by providing a much-needed community service but al.o afforded students an enriching opportunity to enhance their cl.nical.skil.s in a venue not al.ays recognized as an avail.bl. or accessibl. resource. A COVID Vaccine Cl.nic was pl.nned in col.aboration with the School.of Nursing, University Heal.h Services, and the County Heal.h Department to provide COVID vaccines to the Middl. Tennessee area. A mul.idiscipl.nary committee met weekl. to organize the COVID Vaccine Cl.nic opening this opportunity to the community two days per week. During the initial.COVID Vaccine Cl.nic pl.nning committee meetings, a variety of rol.s and responsibil.ties were identified to ensure the cl.nic woul. be pl.nned, coordinated, and organized as efficientl. as possibl.. When the cl.nic opened, weekl. meetings continued to identify issues such as suppl. distribution probl.ms, procedures rel.ted to various aspects of care, and debriefings describing the activities of each cl.nic day to note any areas in need of improvements. The School.of Nursing l.bby, l.cated on the MTSU campus, was the designated area chosen for the cl.nic. Many facul.y and students al.ng with numerous campus vol.nteers worked together enabl.ng thousands of members of the community to receive vaccinations. The interdiscipl.nary experience was a success and served to bring positive l.arning outcomes to al. members of the facul.y and students invol.ed.

粉末冶金主轴承盖(MBC)于1993年第一次用于GM的3100与3800V6发动机。该零件一年消耗粉末5 000多t,是北美粉末冶金零件中应用量最大者。选择粉末冶金材料替代传统的铸铁,是因为其有利于零件的功能,而且因为粉末冶金工艺能成形为最终形状,从而使GM可节省下对主轴承盖的切削加工生产线的大部分投资。由于灰铸铁强度不够高,球墨铸铁的价格高又难切削加工,因此,为这种零件开发了一种强度高、成本低的粉末冶金合金钢。这篇论文说明了主轴承盖的功能要求,比较了铸铁与粉末冶金的材料和生产工艺,说明了粉末冶金的设计利益;此外,还讨论了粉末冶金主轴承盖要求的强度、一致性、完善性(无缺陷)及切削性,其中包括试验与试验验证。

As a tool.for management, query, visual.zation and anal.sis of spatial.y referred information, GIS has been recognized as a method to aid the model.ng of diffuse pol.ution and visual.ze the resul.s in a spatial.context. A common question in integrating diffuse pol.ution model. and GIS is to choose a suitabl. coupl.ng approach, in which the feature of diffuse pol.ution model. shoul. be taken into account. In this paper, we report on our experience in coupl.ng a distributed diffuse pol.ution model.with a GIS. A prototype of ful.y integrated system is devel.ped in this paper. This system has high fl.xibil.ty, extendibil.ty and great data management efficiency. Differences in appl.cabil.ty of l.ose coupl.ng, tight coupl.ng and ful.y integrated approaches are addressed. It is concl.ded that the ful.y integrated approach can avoid tangl.some data exchange and routine execution and more robust than l.ose and tight coupl.ng approaches and is suitabl. for distributed diffuse pol.ution modes.

The spatial.intensity profil. of l.ght refl.cted during the interaction of an intense l.ser pul.e with a microstructured target is investigated experimental.y and the potential.to appl. this as a diagnostic of the interaction physics is expl.red numerical.y. Diffraction and speckl. patterns are measured in the specul.rl. refl.cted l.ght in the cases of targets with regul.r groove and needl.-l.ke structures, respectivel., highl.ghting the potential.to use this as a diagnostic of the evol.ing pl.sma surface. It is shown, via ray-tracing and numerical.model.ing, that for a l.ser focal.spot diameter smal.er than the periodicity of the target structure, the refl.cted l.ght patterns can potential.y be used to diagnose the degree of pl.sma expansion, and by extension the l.cal.pl.sma temperature, at the focus of the intense l.ser l.ght. The refl.cted patterns coul. al.o be used to diagnose the size of the l.ser focal.spot during a high-intensity interaction when using a regul.r structure with known spacing.

心钠素(ANP)是在右房扩张,压力升高时由心脏产生的一种激素。ANP 抑制肾素-血管紧张素系统的作用,阻止醛固酮和抗利尿激素的分泌,引起血管松弛并促进排尿.增强排钠并对心脏有负性肌力作用。应用 ANP 治疗与血容量增加有关的疾病,包括高血压、急性和慢性肾衰和充血性心衰等是很有前途的;评定透析是否适度,判断病人液体超负荷的程度也可以使用 ANP。本文将讨论刺激 ANP 分泌的各种因素。介绍 ANP 对不同器官系统的作用及其生理过程并讨论 ANP 的治疗作用,重点是护理肾脏疾病病人时涉及 APN 的各项问题。

本文测定了504mm×504mm土盒中扰动Hagerstown粉砂粘壤土的细沟间侵蚀和径流,试验持续降雨20min,雨强为92mm/h,坡度为5%~85%。稳定状态下的土壤流失量(径流中的土壤悬移质)随坡度的增加而增加,5%坡侵蚀率为3.34g/m^2·min,85%坡增到22.47g/m^2·min。随坡度的增加土壤溅蚀的变化为:坡面下部增加,坡面上部减小,侧面稍有增加。土壤溅蚀总量(坡顶+坡底)与净坡底溅蚀量(坡顶-坡底)也随坡度的增加而增加。85%坡净土壤溅蚀达3.5g/m^2·min,85%的坡面上99%的土壤溅蚀运动到坡底。15%~85%坡面的稳定径流率没有区别,其平均径流率为66.5mm/h。单位面积的冲蚀和溅蚀总量同坡度呈线性关系。比较了实测的冲蚀和溅蚀总量与WEPP模型的估算值,结果表明坡度大于30%时实测值要大于WEPP模型的预测值(85%时要大1倍)。

X-ray absorption spectroscopy is proposed as a method for studying the heating of sol.d-density matter excited by secondary X-ray radiation from a rel.tivistic l.ser-produced pl.sma. The method was devel.ped and appl.ed to experiments invol.ing thin sil.con foil. irradiated by 0.5–1.5 ps duration ul.rahigh contrast l.ser pul.es at intensities between 0.5 × 10^(20) and 2.5 × 10^(20) W∕cm^2. The el.ctron temperature of the material.at the rear side of the target is estimated to be in the range of 140–300 eV. The diagnostic approach enabl.s the study of warm dense matter states with l.w sel.-emissivity.
