This study focuses on the assessment of herbicide adsorption and degradation in three soils (Haplic Chernozem, Haplic Fluvisol, Arenic Regozem) from different agricultural regions Czech Republic where sunflower is cultivated. Soil samples were used laboratory batch experiments for six herbicides commonly crops. The findings are to examine effect soil properties degradation, as well determine po...

in this research, the bioinsising impact of two wood decay fungi (pysisporinus vitreus and xylaria longipes) on radial air permeability and moisture diffusion coefficient of spruce wood (picea abies) was investigated. fungal cultivation was performed in an incubator at 25 °c and 85% relative humidity for 15, 30 and 45 days. results showed that the permeability, moisture diffusion and mass loss ...

The Hsp70 co-chaperone CHIP has recently gained attention as a regulator of protein turnover. CHIP has now been reported to be a component of the ubiquitination cascade, specifically an E3 ligase. CHIP appears to be part of a system that diverts incorrectly folded proteins from chaperones to the proteasome.

This study demonstrates mathematical description of sewage sludge composting based on identification and separate characterisation of simple process parts. For a description of the microbial processes an aSM3-based mathematical model developed for autothermal thermophilic aerobic sludge digestion is used. The oxygen mass transfer was characterized in a separate way. The 2.964·10-3 m2·d-1 value ...

In this paper we propose an image steganography technique which embeds secret data without making explicit modifications to the image. The proposed method simultaneously provides both imperceptibility and undetectability. We decompose image by contourlet transform and determine nonsmooth regions. Embedding data in these regions cause less degradation in image quality. Contourlet sub-bands are d...

A new adaptive multiple-shift correlation (MSC)-based blind channel equalizer (BCE) for multiple FIR channels is proposed. The performance of theMSC-based BCE under channel order mismatches due to small head and tail channel coefficient is investigated. The performance degradation is a function of the optimal output SINR, the optimal output power, and the control vector. This paper also propose...

VM Migration for Autonomic Fault Tolerance provides the continuous availability for applications in the event of virtual machine failures along with the benefits of improved performance and manageability. Multipath correlation coefficient approach for VM migration has been proposed, which takes into account the overutilization of CPU without performance degradation based on work variability. Th...
