Background and Objectives: Patient Safety Culture is increasingly recognized as an essential driver of patient safety. To establish patient safety culture, firstly the current status of the construct should be assessed. Valid assessment of patient safety culture is contingent on the availability of appropriate measurement tools. Hospital Survey on Patient Safety Culture (HSOPS) developed by th...

For a market with an atomless continuum of assets, we formulate the intuitive idea of a ‘‘well-diversified’’ portfolio, and present a notion of ‘‘exact arbitrage’’, strictly weaker than the more conventional notion of ‘‘asymptotic arbitrage’’, and necessary and sufficient for the validity of an APT pricing formula. Our formula involves ‘‘essential’’ risk, one based on a specific index portfolio...

In this article, an exact analysis of compressors spool in a turbojet engine has been investigated. The spool is modeled as a rotating thick-walled hollow circular cylinder with free-clamp ends. It is subjected to centrifugal load due to its constant rotational speed, uniform internal and external radial loads and arbitrary thermal gradients. The analysis is initially investigated for the homog...

Objective: This study aims to develop and create a tool based on factor analysis to assess safety culture in the processing industry. Methods: This study was conducted in the petrochemical industry in 2021. The questionnaires were distributed among 312 employees, supervisors, and managers, and 308 of them were completed. The validity of the questionnaire was assessed by content and construct v...

background: factor vii concentrates are used in patients with congenital or acquired factor vii deficiency or treatment of hemophilia patients with inhibitors. in this research, immunoaffinity chromatography was used to purify factor vii from prothrombin complex (prothrombin-proconvertin-stuart factor-antihemophilic factor b or ppsb) which contains coagulation factors ii, vii, ix and x. the aim...

the highway safety manual [hsm, 2010] recommends safety evaluations be performed beforeimplementing any roadway treatment to predict the expected safety consequences. safety consequences canbe measured using crash prediction models, crash modification factor (cmfs), or both. this paperdevelops a cmf to show the expected impact of red-light cameras (rlcs) on safety at signalizedintersections. a ...

The present study examined the effect of the geometric parameters of the Rockfill dams on the 2D static analysis of slope stability. In this regard, several numerical models analyzed for eight heights, three slopes of upstream and downstream, three vertical and skewed core thicknesses and four different impounding time stages namely, "End of Construction", "Full Reservoir", "Half Full Reservoir...
