The Study on High-Pressure Solid-Liquid-Gas Phase Equilibrium and Crystallization Behaviors

近年来，超临界流体微粒化/微胶囊化技术迅速发展，在医药、材料、食品等领域有着广阔的应用前景。目前该技术的研究正在朝着更多的体系、更广的领域扩展，但仍存在着基础相行为研究不足、结晶动力学数据缺乏等问题。基于此，本工作将实验测定与理论建模相结合，系统研究多个含CO2或N2的二元、三元体系的固液气（solid-liquid-gas，SLG）相行为，并探索若干物质在高压CO2中的结晶行为。 针对固体-CO2二元体系的SLG相平衡提出一个结合溶解度数据的半预测模型（asemipredictivemodelusingsolubilitydata，SMS）和一个结合剩余性质GE的纯预测模型（acalcul...Supercritical fluid (SCF) technology for manufacturing fine particles or microcapsules has been developed very rapidly in recent years, which is prospective in pharmaceutical, material, and food industries, etc. However, there’re several problems such as insufficient study on phase behavior and the lack of kinetic data for crystallization. Considering those issues, this work combined the measureme...学位：工学硕士院系专业：化学化工学院化学工程与生物工程系_化学工程学号：2062009115125

The main factors affecting the quality and yield of product were investigated. The optimal conditions for reaction were: molar ratio of MF to KOH 1.20:1, molar ratio of HCOOH to KOH 1.44:1, reaction time 30 min and reaction temperature 55℃. The product met the quality standard of potassium diformate after infrared spectrum analysis and composition determination.厦门大学创新性实验计划资助项

Clinical analysis of perimenopausal women presenting initially with dry eye symptom

目的探讨围绝经期妇女的干眼症状与干眼病诊断的相关性。方法分析56例具有干眼症状的围绝经期妇女眼部检查的临床资料,观察主诉为干眼症状患者的干眼病确诊率及其关系。结果56例以干眼症状为主要表现的围绝经期妇女,确诊水液缺乏型干眼17例(30.4%),蒸发过强型干眼12例(21.4%),混合型干眼8例(14.3%);不能诊断干眼病的19例(33.9%),最终诊断为围绝经期综合征。结论围绝经期妇女干眼病确诊率较高(66.1%),但部分干眼症状可以只是围绝经期综合征的精神神经症状的一种表现,临床诊断干眼应慎重。 【英文摘要】 Objective Diagnosis and treatment of dry eye are important for improving living quality.Present paper was to investigate the correlation between dry eye manifestations and diagnosis of dry eye disease in perimenopausal women.MethodsThe clinical data of 56 perimenopausal women presenting initially with dry eye symptoms including ocular symptoms,slit-lamp examination,tear film break-up time,basal and reflex Schirmer test,vital staining(fluorescence and rose bangle),and meibomian gland dysfunction examination ..

臨地実習中の看護学生の生活環境を踏まえたストレスの実態

看護学生にとって臨地実習とは、学内での学習した看護の知識・技術を実践する能力を習得する重要な場であるとともに、身についている生活習慣が崩れることにより、様々なストレス反応が現れる。我々も、実際に臨地実習を経験したなかで、体調を崩などの身体的変化が現れる者、憂欝な気持ちになるといった心理的変化が生じる者などストレスの感じ方や、ストレス反応が個々で異なると感じた

Validation of MALDI-TOF MS devices in reanalysis of unidentified pathogenic bacteria detected in blood cultures

In hospital microbial laboratories, morphological and biochemical analyses are performed to identify pathogenic microbes;however, these procedures lack rapidity and accuracy. Recently, Matrix-Assisted Laser Desorption/Ionization Time-of-Flight Mass Spectrometry (MALDI-TOF MS) has been clinically utilized, and is expected to enable rapid and accurate microbial identification. We aimed to validate two MALDI-TOF MS devices available in Japan: the VITEK-MS (BioMérieux) and the Microflex LT (Bruker Daltonics). Clinically isolated bacteria, 100 samples in all, detected in blood cultures but incompletely identified by conventional procedures, were reanalyzed using the two devices. The VITEK-MS and Microflex LT, respectively, identified 49% (49/100) and 80% (80/100) of the tested bacteria at the species level, as well as 96% (96/100) and 95% (95/100) at the genus level. Among those reidentified strains, 26% (26/100) at the species level and 88% (88/100) at the genus level were concordant with each other, though three strains were unmatched. Moreover, four bacterial strains were unable to be identified using the VITEK-MS, versus five using the Microflex LT. MALDI-TOF MS devices can provide more rapid and accurate bacterial identification than ever before;however, the characteristics of each system were slightly different;therefore, it is necessary to understand the difference in performance of MALDI-TOF MS models
