OBJECTIVE We investigated the association between crowding as measured by ambulance diversion and differences in access, treatment and outcomes between black and white patients. DESIGN Retrospective analysis. SETTING We linked daily ambulance diversion logs from 26 California counties between 2001 and 2011 to Medicare patient records with acute myocardial infarction and categorised patients...

The upper reaches of the Han River are source region water for Middle Route China’s South-to-North Water Diversion Project, mainly household, industrial, and irrigation purposes. Planktonic bacteria more sensitive than macroorganisms to physical chemical properties play a critical role in biogeochemical processes river ecosystems. In November 2017 April 2018, systematic methodical survey was ca...

Abstract Anthropogenic interventions in the form of dams and barrages often alter fluvial functionality eco-geomorphological (geomorphology, hydrology, ecology) behaviour river systems. The present work examines environmental flow, channel metamorphosis, Damodar River context Valley Corporation (DVC) development. Structural (dams, barrages, weirs, etc.) non-structural (urban–industrial agricult...

Abstract Taking the sand mining project in a local river section lower reaches of Yangtze River, as an example, this paper investigates complex effects on potential. Based MIKE21 software to establish two-dimensional water–sand mathematical model section, study change potential near after implementation different schemes through numerical simulation explore influence The results show that (1) e...

Abstract The Yellow River diversion project consists of three gates, two pumping stations, and one plain reservoir, with a total river length 17.46 km in the Panzhuang irrigation area, which provides primary water source for Dezhou central city, Shandong Province, China. is subject to constraints sluice diverting time, reservoir combinations stations self-flowing gates. opening closing forms ga...

This paper will describe the Diversion OffGate Management Assistant (DOGMA) system, a decision-support tool that uses airline-articulated policies to critique dispatcher initiated diversion decisions to ensure that these plans will not only maintain safe operating practices, but will also go further toward providing decision makers with the broad and diverse set of concerns from various stakeho...

This research effort is undertaken to determine the impact that one hospital’s diversion status has on other hospitals in a region and the strength of these interactions. The conditional probability of one hospital going on diversion given that another is already on diversion is evaluated. Based on this analysis, the strength of interactions among the hospitals is established. Through statistic...

A near real-time system is described, which provides spatial information of inland flood extent, using MOderate resolution Imaging Spectrometer (MODIS) optical reflectance and Advanced Microwave Scanning Radiometer (AMSR-E) microwave brightness temperature imagery, and flood volume through combination with a Digital Elevation Model (DEM). This information is an independent and useful addition t...

The disease was first described by Hippocrates in 460-377 BC. Since then it has been reported upon by countless authors. Whenever there is a massive gathering of human population, as in wars, the disease is likely to occur in epidemic form. At other times, the disease shows itself by sporadic cases and occasional epidemics. Thus a remarkable epidemic of 35,000 cases occurred in Delhi in 1955. T...

This paper introduces a new trade model type. It combines the gravity model, well-known in international economics, with network theory. With this approach, complicated trade networks can be algebraically solved in form of systems of linear (differential) equations. Business cycles and productivity shocks can be represented via complex numbers or the Laplace transformation. With the help of thi...
