We study the viscous spatial linear stability characteristics of the time-averaged flow in turbulent subsonic jets issuing from serrated (chevroned) nozzles, and compare them to analogous round jet results. Linear parabolized stability equations (PSE) are used in the calculations to account for the non-parallel base flow. By exploiting the symmetries of the mean flow due to the regular arrangem...

BACKGROUND The death of a simulated patient is controversial. Some educators feel that having a manikin die is prejudicial to learning; others feel it is a way of better preparing students for these situations. Perceived self-efficacy (PSE) reflects a person's perception of their ability to carry out a task. A high PSE is necessary to manage a task efficiently. In this study, we measured the im...

Diffusion-weighted imaging (DWI) has demonstrated a focal area of cytotoxic oedema during partial status epilepticus (PSE). However, vasogenic oedema related to the breakdown of the blood-brain-barrier (BBB) and ictal hyperperfusion could be the predominant DWI findings in the epileptogenic area during PSE. We report a case of PSE with ictal aphasia, right hemiparesis, and repetitive focal moto...

Obesity and its common association with type 2 diabetes, dyslipidemia, and cardiovascular diseases are worldwide epidemics. Currently, to prevent or treat obesity and associated metabolic disorders, herbal dietary supplements or medicines have attracted more and more attention owing to their relative effectiveness with fewer significant side effects. We investigate the therapeutic effects and u...

BACKGROUND Aqueous pomegranate seed extract (PSE), a by-product of the pomegranate juice industry, was recently identified as a potential antiglycative ingredient. Ellagic acid was proposed as the major polyphenol responsible for the antiglycative activity as exerted in in vitro models. However, there is no information on safety aspects of this extract in biological systems before its applicati...

The aim of this study was to examine the relationship between biopsychosocial functioning and pain severity and to evaluate whether pain self-efficacy (PSE) mediates this relationship. This study used archival data from a multidisciplinary pain management program. Participants were 99 individuals (69% female) with chronic low back pain who completed measures of biological, psychological, and so...

Patient safety events (PSEs) are common in healthcare and may be particularly prevalent in complex care settings such as emergency departments (EDs). Systems for reporting, analyzing, learning from and responding to incidents are promoted as a means to reduce adverse events by facilitating feedback, learning and system change. However, only 4-50% of PSEs are reported. Under-reporting masks the ...

BACKGROUND There is strong evidence indicating that gut microbiota have the potential to modify, or be modified by the drugs and nutritional interventions that we rely upon. This study aims to characterize the compositional and functional effects of several nutritional, neutraceutical, and pharmaceutical cardiovascular disease interventions on the gut microbiome, through metagenomic and metabol...

Based on the construction strategy of PSE with Web service, the framework of land suitability assessment PSE is created, and a prototype of land suitability assessment information system is designed and developed partially. The land suitability of Huangpi district Wuhan city is taken as a case to test the prototype system, and the result shows that the method is valid and efficient.
