We present an analysis of the X-ray properties of sources detected in the 13H XMM-Newton deep (200ks) field. In order to constrain the absorbed AGN population, we use extensive Monte Carlo simulations to directly compare the X-ray colours of observed sources with those predicted by several model distributions. In particular, we have carried out our comparisons over the entire 0.2–10 keV energy ...

A positive association between deoxcholic acid (DCA) in the serum and colorectal adenomas, the precursors of colorectal cancer has recently been found, which supported the hypothesis of a pathogenic role of DCA in colonic carcinogenesis. This approach was based on the hypothesis that DCA formed in the colon is absorbed into the portal venous blood and exhibits a constant spillover to the system...

To estimate the time delay between the planetary temperature change and the change of the incoming solar radiation fraction absorbed by the ocean and the atmosphere, the analytical energy balance model is presented. The model generalization allows of using averaged data for model parameterization. Using the model, the time delay is investigated on four model cases of absorbed radiation change. ...

PURPOSE The aim of the study was the prediction of human intestinal permeability and fraction absorbed of oral dose using single-pass intestinal perfusion technique (SPIP) in rats. METHODS Permeability coefficients in anaesthetized rats were determined for 14 compounds. Drug solution in phosphate buffered saline (PBS) was perfused through a ingle-pass intestinal perfusion (SPIP) with flow rat...

In the large helical device (LHD), direct oblique launching of the extraordinary (X-) mode from the high magnetic field side is available without installation of any additional mirror or installation of a launcher in the inner side of the torus. The launched X-mode first encounters the electron cyclotron resonance (ECR) layer from the high magnetic field side and then approaches the upper hybri...

We have determined the cosmological evolution of the density of active galactic nuclei (AGN) and of their NH distribution as a function of the un–absorbed 2–10 keV luminosity up to redshift 4. We used the HELLAS2XMM sample combined with other published catalogs, yielding a total of 508 AGN. Our best fit is obtained with a luminosity-dependent density evolution (LDDE) model where low luminosity ...
