background and objective: prostate cancer is a prevalent disease around the world. the prostatic specific antigen (psa) test has recently proved itself as a useful method for the diagnosis and examination of patients with prostatic cancer. the objective of this study was to compare the stability of free psa and total psa in different storage settings. materials and methods: samples were obtaine...

a r t i c l e i n f o JEL classification: C18 C51 Keywords: Temperature Time series model Weather derivatives Seasonality GARCH In this paper we present a stochastic model for daily average temperature. The model contains seasonality, a low-order autoregressive component and a variance describing the heteroskedastic residuals. The model is estimated on daily average temperature records from Sto...

We use a Green's function method to study the temperature-dependent average moment and magnetic phase-transition temperature of the striped antiferromagnetism of LaFeAsO, and other similar compounds, as the parents of FeAs-based superconductors. We consider the nearest and the next-nearest couplings in the FeAs layer, and the nearest coupling for inter-layer spin interaction. The dependence of ...

gradual increase of the earth's surface temperature can cause many significant changes on the climate of our planet. this problem is progressively increasing. one of the main reasons for this phenomenon is the absorption of the sun's energy and lack of proper reflection of emissions due to man-made activities, one of which is the increase in black surfaces. in this descriptive and cross-section...

in recent years, mangrove forests with the high economical and environmental value are threatened with extinction by human activities. ex-situ conservation is an appropriate method to conservation this forest. this study was conducted with the purpose of studying the role of climatology factors as one of the most important environmental parameters in dispersion of mangrove forests of hormozgan ...
