This study aims to examine the relationship between lexical knowledge towards understanding tertiary students’ academic lexical competence. The study investigates the lexical knowledge variables (passive vocabulary’s breadth and depth, controlled active vocabulary’s breadth and depth, free active vocabulary’s breadth and depth) and lexical competence variables (passive vocabulary competence, controlled active vocabulary competence, and free active vocabulary competence) pertaining to the Academic English performance of selected Universiti Sains Malaysia (USM) tertiary students. This study adopts the quantitative-based cross sectional survey method. The participants consisted of 155 tertiary students of the Academic English course chosen from USM which were selected based on the stratified random sampling method
To investigate the reasons and nursing strategies of postoperative return to ICU in patients with severe valvular disease
目的 探讨重症瓣膜置换病人术后再次非计划性返回ICU的重返率及原因。根据原因分析建立最佳护理模式及干预策略,通过护理干预手段降低重返率,提高治愈率及患者术后康复质量。方法 回顾性分析2010年6月—2015年6月间150例重症瓣膜置患者术后重返ICU患者的临床资料、分析重返的原因。结果 150例重症瓣膜置换患者术后非计划重返ICU的患者有17例,重返率为11.3%。重返的主要原因是呼吸困难、恶性心律失常、低心排、循环负荷过重、家属照护压力大主动要求重返ICU等。结论 制定合理的转出标准;合理配置人力资源,动态监测,密切观察患者生命体征、出入量平衡、电解质平衡;提供个性化健康指导提高患者及家属的遵医行为是降低ICU重返率的有效措施。Objective: To investigate the return rate and causes of postoperative non - planned return to ICU in patients with severe valve replacement. According to the analysis of the reasons, establish the best nursing model and intervention strategies, through the nursing intervention to reduce the return rate, and improve the cure rate and postoperative rehabilitation quality. Methods: Retrospective analysis of clinical data of 150 cases of severe valvular replacement patients who returned to ICU in June, June 2010, and the reasons for the return of ~2015. Results: 150 cases of patients with severe heart valve replacement patients, among them 150 cases had no plan to return to ICU, the return rate was 11.3%. The main reason to return to ICU is the difficulty of breathing, malignant arrhythmia, low cardiac output, overweight, family care pressure and so on n. Conclusion: To establish a reasonable standard of transfer; the rational allocation of human resources, dynamic monitoring, close observation of vital signs of patients, access to balance, electrolyte balance; providing personalized health guidance to improve the compliance behavior of patients and their families are the effective measures to reduce the ICU readmission rate.
Phenol Adsorption on Nitrogen-Enriched Activated Carbon from Wood Fiberboard Waste
Nitrogen-enriched activated carbons were prepared from wood fiberboard waste using 50% potassium hydroxide solution. Activated carbons were obtained with an impregnation ratio (gram chemical agent/gram wood fiberboard waste) of 3 in 850°C activation temperature carbonized for 60 min. Nitrogen content in activated carbon was 1.33% by analysis. Effects of contact time, pH, adsorbent dosage level, and temperature on phenol adsorption capacity of activated carbons were investigated. Adsorption equilibrium was achieved within 100 min at the given phenol concentration of 250 mg/L. When 0.1 g of the carbon absorbent and 100 mL of phenol solution at 250 mg/L were used, maximum adsorption capacity of phenol on activated carbon can reach 207 mg/g. The kinetics of phenol adsorption followed nicely the pseudo-second-order rate expression. In the adsorption isotherm, the Langmuir model fit better than the Freundlich model in phenol adsorption. This study suggests that nitrogen-enriched activated carbon prepared from wood fiberboard waste can be used effectively for removal of phenol compounds from aqueous solutions
Poly[[2-(3-pyridinio)-1H,3H +-benzimidazolium] [μ4-oxido-di-μ3-oxido-tetra-μ2-oxido-hexaoxidotetramolybdenum(VI)]]
The reaction of MoO3 with 2-(3-pyridyl)benzoimidazole and water in the presence of MnSO4·5H2O at 453 K under hydrothermal conditions afforded the title compound, {(C12H11N2)[Mo4O13]}n, in which infinite molybdenum oxide anionic chains are charge-balanced by diprotonated 2-(3-pyridyl)benzoimidazole (H23-PBIM2+) cations. Eight [MoO6] octahedra are edge-shared, forming compact octamolybdate subunits which are connected through pairs of Mo—O—Mo bridges into extended one-dimensional arrays propagating along the a-axis direction. The asymmetric unit of the metal oxide chain contains one half of the octamolybdate unit, denoted [Mo4O13], the other half being generated by an inversion center. These molybdenum oxide chains are further connected through the 2-(3-pyridinio)benzoimidazolium cations into a three-dimensional network via N—H⋯O hydrogen bonds. In addition, neighbouring diprotonated cations are arranged in a head-to-tail fashion with a plane-to-plane separation of 3.63 (10) Å, indicating the existence of weak aromatic π–π stacking interactions
Preparation and characterization of spindle-like Fe3O4 mesoporous nanoparticles
Magnetic spindle-like Fe3O4 mesoporous nanoparticles with a length of 200 nm and diameter of 60 nm were successfully synthesized by reducing the spindle-like α-Fe2O3 NPs which were prepared by forced hydrolysis method. The obtained samples were characterized by transmission electron microscopy, powder X-ray diffraction, attenuated total reflection fourier transform infrared spectroscopy, field emission scanning electron microscopy, vibrating sample magnetometer, and nitrogen adsorption-desorption analysis techniques. The results show that α-Fe2O3 phase transformed into Fe3O4 phase after annealing in hydrogen atmosphere at 350°C. The as-prepared spindle-like Fe3O4 mesoporous NPs possess high Brunauer-Emmett-Teller (BET) surface area up to ca. 7.9 m2 g-1. In addition, the Fe3O4 NPs present higher saturation magnetization (85.2 emu g-1) and excellent magnetic response behaviors, which have great potential applications in magnetic separation technology

Methods: Set a total of 63 questionnaires for all the medical technical personnel. Results: 100% staffs know that now integration mode is carried out in the department, member of medical integration group, familiar with the medical work pattern of the integration process, the post responsibility, and the implementation of medical integration of medical integration made. Doctors and nurses technicians work with more understanding. 98.7% staff believes that the quality of medical care of the patient was obviously improved after the implementation of medical integration work mode. 98% the medical staff believes that self-efficacy has been improved obviously. 97.8% the medical staff think that self-management ability of patients is improved and the implementation of the medical integration mode identification. Conclusion: The implementation model of integrated management of patient care improves the medical staffs’ activeness, expanding knowledge, improving the clinical thinking ability, the majority of doctors and nurses recognition. At the same time publicity and training should be enhanced so that more medical personnel understand the medical integration efforts
