cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
The ionizing radiations, through physical and chemical processes, lead to simple and complex single- and double- strand breaks, as well as base lesions to the DNA. In this study, taking into account all the physical and chemical processes involved in the interaction of ionizing radiation with matter, the initial damage induced to DNA was evaluated for 5.7 MeV alpha-rays from Radon 223 isotope....
Neuronal and astroglial cells were prepared from whole brain of three month and 30-month- old rats for study of alterations in the nuclear poly ADP-ribosylation and DNA breaks with age. The relative purity of the cell preparations was confirmed by the determination of the neurofilament (low molecular weight) and glutamine synthetase content of the cells using ELISA. An increase (75%) in th...
We discuss the increasing literature on misspecifying structural breaks or more general trends as long range dependence We consider tests on structural breaks in the long memory regression model as well as the behaviour of estimators of the memory parameter when structural breaks or trends are in the data but long memory is not It can be seen that it is hard to distinguish deterministic trends ...
is motivated by applications in order statistics: its distribution naturally appears in the consideration of the reliability of the procedure of determination of a theoretical distribution by drawing of a random sample. Namely, in the case when the sample size N is a Poissonian random variable, see Kac (1949a). The distribution function of the functional (1) was determined explicitly by Takács ...
