metal oxide surge arrester accurate modeling and its parameter identification are very important for insulation coordination studies, arrester allocation and system reliability. since quality and reliability of lightning performance studies can be improved with the more efficient representation of the arresters´ dynamic behavior. in this paper, big bang – big crunch and hybrid big bang – big cr...

The aim of this paper is to determine the extent to which it is possible to establish a ‘base’ and ‘surge’ strategy for logistics provision with a particular emphasis on minimising environmental and economic costs. Our method is the combination of empirical research outputs on the impact of uncertainty on economic and environmental costs, and a synthesis of the literature on resilience and the ...

Abstract According to the concept of “flexible surge capacity,” hospitals may need be evacuated on two occasions: (1) when they are exposed danger, such as in war; and (2) contaminated, during Covid-19 pandemic. In former, entire hospital must evacuated, while latter, becomes a pandemic center necessitating transfer its non-contaminated staff, patients, routine activities other facilities. Such...

OBJECTIVE To assess the adequacy of preparedness planning for an influenza pandemic by modeling the pediatric surge capacity of healthcare facility and pediatric intensive care unit (PICU) requirements over time. Governments and Public Health authorities have planned preparedness activities and training for a flu pandemic. PICU facilities will be the limiting factor in healthcare provision for ...

INTRODUCTION In recent years, government and hospital disaster planners have recognized the increasing importance of pharmaceutical preparedness for chemical, biological, radiological, nuclear, and explosive (CBRNE) events, as well as other public health emergencies. The development of pharmaceutical surge capacity for immediate use before support from the (US) Strategic National Stockpile (SNS...

We qualitatively examined the impact of the permanent closure of St. Vincent's Hospital in New York City on the remaining hospitals in the area and analyzed how these hospitals responded to this event. We conducted a descriptive survey consisting of interviews with clinical (n = 24) and administrative (n = 11) staff from 4 hospitals in lower Manhattan after the sudden closure of St. Vincent's H...

The government announced this week that it was rolling out additional surge testing and sequencing capacity to a small number of UK locations where community based infections the covid-19 variant first identified in South Africa (known as 501Y.V2) were found could not be linked back international travel. To date, 11 cases kind have been identified. Surge is being targeted eight postcode areas ...

Background. Post-exposure prophylaxis is a critical component of the public health response to bioterrorism. Computer simulation modeling may assist in designing antibiotic distribution centers for this task. Methods. The authors used discrete event simulation modeling to determine staffing levels for entry screening, triage, medical evaluation, and drug dispensing stations in a hypothetical an...

Disasters serve as shocks and precipitate unanticipated disturbances to the health care system. Public health surveillance is generally focused on monitoring latent health and environmental exposure effects, rather than health system performance in response to these local shocks. The following intervention study sought to determine the long-term effects of the 2005 chlorine spill in Granitevill...

STUDY OBJECTIVE Hospital evacuations have myriad effects on all elements of the health care system. We seek to (1) examine the effect of patient surge on hospitals that received patients from evacuating hospitals in New York City during Hurricane Sandy; (2) describe operational challenges those hospitals faced pre- and poststorm; and (3) examine the coordination efforts to distribute patients t...
