BACKGROUND Heat periods during recent years were associated with excess hospitalization and mortality rates, especially in the elderly. We intended to study whether prolonged warmth/heat periods are associated with an increased prevalence of disorders of serum sodium and potassium and an increased hospital mortality. METHODS In this cross-sectional analysis all patients admitted to the Depart...

We use Bayesian statistical methods to compare the habit persistence asset pricing model of Campbell and Cochrane, the long run risks model of Bansal and Yaron, and the prospect theory model of Barberis, Huang, and Santos. We undertake two types of comparisons, relative and absolute, over two sample periods, 1930–2008 and 1950–2008, using two series, univariate U.S. stock returns and bivariate ...

zaki’s reef is located in the gulf of suez, a narrow portion of the red sea, with exceptionally dry and hot climate and lacks almost all scientific data. this research intends to describe the area’s unique climatology, which may reveal correlations between the reef’s existence at high latitude and extreme climate conditions. air temperature at zaki’s reef fluctuated between 0.3 and 58.6oc with ...

The research aimed to analyzing the proportion of daily abundance phytoplankton based on change in time best incubation period. implementation from November 2018 January 2019 marine waters Barrang Lompo Island. Water samples identify were taken by filtering 100 liters seawater using a plankton net. sampling was carried out at observation 10:00; 11.00; 12.00; 13.00; 14.00 period (10.00-14.00). B...

Until the end of 2003 a urinary concentration of pseudoephedrine exceeding 25 microg/mL was regarded as a doping violation by the World Anti-Doping Agency. Since its removal from the prohibited list in 2004 the number of urine samples in which pseudoephedrine was detected in our laboratory increased substantially. Analysis of 116 in-competition samples containing pseudoephedrine in 2007 and 200...

The associations were quantified between daily and interannual variation in the timing of a closed population of lake sturgeon Acipenser fulvescens migration and arrival at spawning sites with stream environmental and lunar covariates. Spawning data were gathered from 1262 fish in Black Lake, Michigan 2001 to 2008 and by video monitoring 2000 to 2002. Sex-specific variation in responses to exte...

BACKGROUND Many previous studies have documented seasonal variation in suicides globally. We re-assessed the seasonal variation of suicides in Finland and tried to relate it to the seasonal variation in daylength and ambient temperature and in the discrepancy between local time and solar time. METHODS The daily data of all suicides from 1969 to 2003 in Finland (N = 43,393) were available. The...
