激光泪道成形术联合鼻泪管支架植入治疗慢性泪囊炎的护理

目的探讨激光泪道成形术联合鼻泪管支架植入治疗慢性泪囊炎的护理。方法通过对慢性泪囊炎患者82例(88只眼)行激光泪道成形术联合鼻泪管支架植入治疗,观察其疗效,总结分析术前、术后的护理措施。结果通过术前、术后的精心护理,随访3-24月,慢性泪囊炎治疗的有效率97%,无效率占3%。结论对激光泪道成形术联合鼻泪管支架植入的慢性泪囊炎患者行相应的护理措施极其重要,能最大限度地减轻患者手术的痛苦,减少手术并发症的发生,大大提高本手术治疗的成功率。     

Fluid Flow Characteristics of String Reactors Packed with Spherical Particles

A hydrodynamic investigation of three geometries of string pellet reactors filled with spheres was conducted. Two geometries were circular spiral channels, while the third was a straight horizontal square channel. Stimulus‐response experiments provided data for residence time distribution analysis from which Pe numbers and liquid holdup were deduced. Flow regimes and transitions were determined from visual observations through the transparent tube wall. For the whole range of the experimental conditions applied in this work and for all reactors, the ratio of gas to liquid velocities, V_g/V_l, is a controlling parameter for Pe number, holdup, and pressure drop.

家庭因素对高护生职业生涯规划的影响

目的：了解不同家庭环境对高护生职业生涯规划及职业决策困难程度的影响,为针对性开展护生职业生涯教育提供理论依据。方法：采用《护生职业生涯规划问卷》和《大学生职业决策困难问卷》量表对300名护生进行分层调查。结果：不同生源地、有无父母参与的高护生个人职业生涯规划评分、职业决策困难评分均有统计学意义（P〈0.05）。结论：高护生缺乏职业生涯规划,职业决策困难水平处于中等,农村、无父母参与的护生更明显,应重点加强这类护生的职业生涯规划教育。

A correction on a one-dimensional model for conical spouted beds published in chemical engineering and processing, 48 (2009) 1264–1269

A one-dimensional model published previously for spouted beds is evaluated. Certain errors exist in the governing equations which are modified and corrected in this Letter to Editor. It is confirmed that this is an efficient model as it needs few number of empirical correlations to solve.     

A model for cluster size in risers

Particles in gas-solid flows aggregate to move as “clusters” and simultaneously develop gas “voids” free of particles. A model for gas-solid flow in risers considering the presence of clusters and voids is presented. Equations are developed to estimate the size of clusters considering “ratio of cluster volume to void volume to be equal to the ratio of cluster volumetric fraction to void volumetric fraction in the bed”. Estimates of cluster size compare well with the experimental observations reported in the literature. Equations developed for slip ratios and gas to particle effective drag coefficients are inline with the trends reported in the literature.

彩华沟黄铁矿型铜矿床位于南天山东段、塔里木北缘活动带南天山晚古生代陆缘盆地.矿床赋存在下泥盆统阿尔彼什麦布拉克组中亚组强硅化的中酸性火山岩中.矿床自北而南出露5条矿化蚀变带,彼此间大致平行,为火山喷溢—沉积改造型的块状含铜黄铁矿矿床.在概述其地质特征、矿床成因的基础上,对物探瞬变电磁(TEM)异常特征和找矿标志进行分析...     

心理护理在助产中的应用效果分析

目的分析心理护理在助产中的临床效果。方法将我院263例孕产妇随机分为2组,对照组130例孕产妇采用常规护理,观察组133例孕产妇在常规护理的基础上加强心理护理,比较分析2组的护理效果。结果观察组孕产妇对护理人员的信任度为97.74%,满意率为98.50%,均高于对照组(均P<0.05)。结论对孕产妇在常规护理的基础上加强心理护理,可以明显提高孕产妇对护理人员的信任度和满意率,利于孕产妇的顺利分娩,值得临床关注。
