This paper reports an ongoing research work that looked at: the resilience of the structure of healthcare facilities, equipment stability, lifeline (utility) supplies, the interaction between hospitals and emergency agencies and the support the latter can provide during major emergencies. This paper presents findings on the ability of human resources to deal with the stress associated with major hazards. A mixed research method was adopted, including a systematic literature review followed by a survey to gather evidence about the stress level amongst healthcare staff in hospitals and their motivation. The literature review was conducted to find information about the level of stress healthcare staff experience with during major emergencies. Findings suggest that healthcare staff remain at high risk of stress and thus represent a major weakness of healthcare service resilience. The research concludes with a set of recommendations to address this issue.</p></div>","PeriodicalId":20470,"journal":{"name":"Procedia Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeng.2018.01.059","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76760217","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Welding is considered a highly complex metallurgical process that results in irregular geometries, material imperfections/flaws and tensile residual stresses. High tensile residual stresses and stress concentrations resulting from the weld process have a significant impact on fatigue life of structures, and thus a topic of great concern in product design. Ultrasonic impact treatment (UIT) is regarded as one of the most effective post welding treatment techniques to enhance the fatigue performance of welded structures. The UIT aims to introduce fatigue-beneficial compressive stresses by plastically deforming the weld toe and reduce stress concentrations by modifying local weld geometries. In this study, 3D modeling and simulation using finite element (FE) method has been performed to simulate welding process and numerical modeling of the UIT process to predict weld residual stress distribution of butt and T weld joints. The predicted numerical results under as-welded and UIT treatment conditions were compared to present weld residual stress improvements. Compared results shows that the UIT has potential applications on the fatigue design of welded structures, can lead to lighter structures and products, in which structures can be down-sized and optimized to reduce weights.</p></div>","PeriodicalId":20470,"journal":{"name":"Procedia Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeng.2018.02.005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77944324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Much attention has been paid to fire extinguishing efficiency of alkali metal salts and ammonium phosphate salts, but the effects of particle sizes have not been studied sufficiently. The fire-extinguishing efficiency of a new kind of agent based on magnesium hydroxide of different particle size was studied in this paper. Four different size powders have been used to study their fire-suppression efficiency through laboratory scale experiments in a confine space of 1*1*1m. The physical and chemical characteristics of the magnesium hydroxide powders were characterized by scanning electron microscopy (SEM) and thermal gravity analysis (TGA). The results have exhibited that these four kinds of powders are all high efficient for the fire suppression efficiency and there is a threshold value of 5μm for the fire suppression efficiency of magnesium hydroxide. The efficiency can be affected by the morphology of powders and particle size. The powders of larger specific surface area and smaller particle size are more efficient to suppress fire. Fire extinguishing and possible fire-suppression mechanisms have also been analyzed from three aspects: chemical inhibition, cooling effect and asphyxiation effect.</p></div>","PeriodicalId":20470,"journal":{"name":"Procedia Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.proeng.2017.12.035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79914579","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
