Introduction: Nursing is highly demanding and stressful profession. Negative consequences of job demands were widely discussed throughout the literature like;poor quality of care, poor health, burnout, greater intent to leave and lower level of job satisfaction. Job dissatisfaction among nurses also has been discussed exhaustively in the literature in regards to its negative outcomes represented by burnout, absenteeism, turnover, greater intent to leave and finally leaving nursing profession. Purpose: The purpose of this study was to examine literature discussing job demands in nursing profession and its associated factors among nurses, and to provide direction as to where research needs to continue to explore and develop evidence in this area. Results: Results showed that job demands are the most influential stressor in nursing profession that associated strongly with many negative consequences on the profession in general and on the nurses on particular. Conclusion: The results supported that job demand is unavoidable stressor that leads to many negative consequences and connects directly to job dissatisfaction. Therefore, there is a need to search for alleviating factors that decrease nursing stressor, its consequences and buffer the correlation between job demand and job satisfaction.

New Pneumatic System for Tidal Energy Conversion

引用

Journal of Power and Energy Engineering 2016年第12期4卷 20-27页

作者： Mamdouh El Haj Assad Ehab bani-hani Ahmad Sedaghat ali Al-Muhaiteeb Khalil Khanafer Malathe Khalil SREE Department University of Sharjah Sharjah United Arab Emirates Mechanical Engineering Department School of Engineering Australian College of Kuwait Safat Kuwait

In this work, a new device for tidal energy conversion is presented. The main purpose of this research is to investigate the energy conversion of tidal energy into electrical one by building a small scale prototype using a pneumatic system representing the energy conversion device. The tidal energy conversion device consists of a concrete in cylindrical shape, a moving base that moves inside the concrete cylindrical body and two single acting pistons connected to a power turbine. The system specifications that mainly affect the amount of energy are the spring stiffness and hose diameter. It was found that there is a possibility to convert the tidal energy into electrical energy using the designed prototype. The maximum amount of electricity generated using the proposed prototype was about 5 Volts.

BACKGROUND Pancreatic cystic lesions(PCLs) are common in clinical practice. The accurate classification and diagnosis of these lesions are crucial to avoid unnecessary treatment of benign lesions and missed opportunities for early treatment of potentially malignant *** To evaluate the role of cyst fluid analysis of different tumor markers such as cancer antigens [e.g., cancer antigen(CA)19-9, CA72-4], carcinoembryonic antigen(CEA), serine protease inhibitor Kazal-type 1(SPINK1), interleukin 1 beta(IL1-β), vascular endothelial growth factor A(VEGF-A), and prostaglandin E2(PGE2)], amylase, and mucin stain in diagnosing pancreatic cysts and differentiating malignant from benign *** This study included 76 patients diagnosed with PCLs using different imaging modalities. All patients underwent endoscopic ultrasound(EUS) and EUS-fine needle aspiration(EUS-FNA) for characterization and sampling of different *** The mean age of studied patients was 47.4 ± 11.4 years, with a slight female predominance(59.2%). Mucin stain showed high statistical significance in predicting malignancy with a sensitivity of 87.1% and specificity of 95.56%. It also showed a positive predictive value and negative predictive value of 93.1% and 91.49%, respectively(P alignancy in PCLs showed a statistically significant positive correlation with mural nodules, lymph nodes, cyst diameter, mucin stain, and cyst fluid CEA. Meanwhile, logistic multivariable regression analysis proved that mural nodules, mucin stain, and SPINK1 were independent predictors of malignancy in cystic pancreatic *** EUS examination of cyst morphology with cytopathological analysis and cyst fluid ana
