BACKGROUND This study assesses the relationship between daily numbers of deaths and variations in ambient temperature within the city of Skopje, R. Macedonia. METHODS The daily number of deaths from all causes, during the period 1996-2000, as well as those deaths from cardiovascular diseases, occurring within the city of Skopje were related to the average daily temperature on the same day usi...

The potential use of shade covers to reduce evaporation from agricultural reservoirs motivated this study on the effect of black polyethylene shade on the evaporation rate from a small water body (Class-A pan) and of its driving variables. Evaporation was measured hourly in two pans during the summer in Cartagena (Spain), along with the measurements of air temperature and humidity, water temper...

total population of hormozgan pro vince of iran was 760,014 in 1365 and 10,045,085 in 1375, which shows a growth rate of %3/2 in 10 years. in comparison with other provinces. the growth rate is one of the highest in the country. th e aim of this study was to determine the fertility of hormozgan province. the method of study was cross - sectional and the sampling in a two stage s sampling of 200...

evaporation, as a major component of the hydrologic cycle, plays a key role in water resources development and management in arid and semi-arid climatic regions. although there are empirical formulas available, their performances are not all satisfactory due to the complicated nature of the evaporation process and the data availability. this paper explores evaporation estimation methods based o...

We study the distribution of fluctuations of the S&P 500 index over a time scale deltat by analyzing three distinct databases. Database (i) contains approximately 1 200 000 records, sampled at 1-min intervals, for the 13-year period 1984-1996, database (ii) contains 8686 daily records for the 35-year period 1962-1996, and database (iii) contains 852 monthly records for the 71-year period 1926-1...

In this study we model the daily rainfall occurrence using Markov Chain Analogue Yearmodel (MCAYM) and the intensity or amount of daily rainfall using three different probability distributions; gamma, exponential and mixed exponential distributions. Combining the occurrence and intensity model we obtain Markov Chain Analogue Year gamma model (MCAYGM), Markov Chain Analogue Year exponentia...

The article provides an overview of all known 39 localities the Paleogene turtles Eastern Europe. Numerous remains are described for first time from 19 localities, which six new, and 13 materials were only mentioned previously. Among them Pan-Trionychidae indet., Pan-Cheloniidae Dermochelyidae indet. Pan-Testudines as well pan-cheloniids Argillochelys sp. Ypresian Novoivanovka or Lutetian Gruzi...

To perform dynamic tumor tracking (DTT) for clinical applications safely and accurately, gimbaled head swing verification is important. We propose a quantitative gimbaled head swing verification method for daily quality assurance (QA), which uses feature point tracking and a web camera. The web camera was placed on a couch at the same position for every gimbaled head swing verification, and cou...
