What determines the Czech land market prices? Some regional findings

The paper deals with the analysis of market land prices that were collected from land purchased contracts in the Czech Republic. Regression model was used to identify determinants explaining variability of market prices between 2008 and 2009. It was found out that type of plantation, region, type of buyers, plot size, distance to regional city or number of parcels play significant role. These factors explain more than a half of variance in land price. Quality of land that was expressed through administrative price has significant effect on market price. Yet, such effect became less import in regions nearby cities (e.g. Prague and Olomouc), where the market land price is significantly influenced by the distance to the district city. Land reform, however has not been confirmed to stimulate higher prices for sellers. It is reasonable to expect that part of the remaining variation could still be accounted for by non-random variables.Land, market price, administrative price, regression model, region., Land Economics/Use, GA, IN,

X-ray imaging with compound refractive lens and microfocus X-ray tube

Compound refractive lenses (CRL), consisting of a lot number in-line concave microlenses made of low-Z material were studied. Lenses with focal length 109 mm and 41 mm for 8-keV X-rays, microfocus X-ray tube and X-ray CCD camera were used in experiments. Obtained images show intensity distribution of magnified microfocus X-ray source focal spot. Within the experiments, one lens was also used as an objective lens of the X-ray microscope, where the copper anode X-ray microfocus tube served as a source. Magnified images of gold mesh with 5 microns bars were obtained. Theoretical limits of CRL and experimental results are discussed

(Oxyanions of halogens in drinking water )

This paper looks at chemistry of individual oxyhalogens such as chlorite, chlorate, perchlorate and bromates, their origin in drinking water and health effects which restrict their concentrations. It is concluded that with understanding of mechanisms of formation of individual oxyhalogens and undertaking practical steps during water treatment and disinfection processes their concentration can, in the majority of cases, be controlled within the drinking water guideline limits
