QUESTIONS UNDER STUDY To investigate changes to health insurance costs for post-discharge postpartum care after the introduction of a midwife-led coordinated care model. METHODS The study included mothers and their newborns insured by the Helsana health insurance group in Switzerland and who delivered between January 2012 and May 2013 in the canton of Basel Stadt (BS) (intervention canton). W...

In 2001 the CRABEL score was devised in order to obtain a numerical score of the standard of medical note keeping. With the advent of electronic discharge letters, many components of the CRABEL score are now redundant as computers automatically include some documentation. The CRABEL score was modified to form the e-CRABEL score. "Patient details on discharge letter" and "Admission and discharge...

Long-term (20 yr) river discharge records from 30 of the world’s largest river basins have been used to characterize surface hydrologic flows in relation to net precipitation inputs, ocean climate teleconnections, and human land/water use patterns. This groundwork study is presented as a precedent to distributed simulation modeling of surface hydrologic flows in large river basins. Correlation ...

prediction the river flow discharge values are important in the surface water resources management. find an appropriate model to accurately predictionof this parameter is one of the most important ways to simulation and prediction. in this study three anfis, svm and gp models were evaluated and compared to modeling the monthly flow discharge of nazloochi river in tapik hydrometric station that ...

     Knowledge of river discharge and water-quality trend can be useful for planning and management of water resources. Due to the fact that the river base flow is supplied by ground water, considering of base flow for managing environmental demand. The Mann-Kendall's test is one of the approaches which is used for investigating of the trend in time series. In this study, the Mann-Kendall's tes...

Streamflow processes of 12 rivers in western Europe are investigated for trend and nonstationarity in the full 100-year period in the 20 century. Trend analyses with Mann–Kendall test show that there is no trend in annual mean discharges. Only three annual maximum flow series exhibit significant trends (Rhine and Moselle, upward; Rhone, downward). There are two minimum flow series exhibiting si...

Globally, tropical and subtropical regions have experienced an increased frequency and intensity in extreme weather events, ranging from severe drought to protracted rain depressions and cyclones, these coincided with an increased number of marine turtles subsequently reported stranded. This study investigated the relationship between environmental variables and marine turtle stranding. The env...

The time course of ambient benzene level and benzene discharge was investigated. Data obtained by continuous monitoring and monthly monitoring showed a decreasing trend of ambient benzene level. The rate of decrease was around 22-25% per two years from FY 1997 to FY 1999. The discharge data of benzene reported by several organizations were collected and re-arranged to estimate the total dischar...

it is necessary to use empirical models for estimating of instantaneous peak discharge because of deficit of gauging stations in the country. hence, at present study, two models including artificial neural networks and nonlinear multivariate regression were used to predict peak discharge in taleghan watershed. maximum daily mean discharge and corresponding daily rainfall, one day antecedent and...
