BACKGROUND Mitochondrial DNA polymerase gamma (POLG1) mutations were associated with levodopa-responsive Parkinsonism. POLG1 gene contains a number of common nonsynonymous SNPs and intronic regulatory SNPs which may have functional consequences. It is of great interest to discover polymorphisms variants associated with Parkinson's disease (PD), both in isolation and in combination with specific...

In this paper we present an algorithm for counting points on elliptic curves over a finite field Fpn of small characteristic, based on Satoh’s algorithm. The memory requirement of our algorithm is O(n), where Satoh’s original algorithm needs O(n) memory. Furthermore, our version has the same run time complexity of O(n) bit operations, but is faster by a constant factor. We give a detailed descr...

The metabolism of 1-(3,4-dichlorobenzyl)-5-octylbiguanide (OPB-2045), a new potent biguanide antiseptic, was investigated using rat and dog liver preparations to elucidate the mechanism of OPB-2045 metabolite formation, in which the octyl side chain is reduced to four, five, or six carbon atoms. Chemical structures of metabolites were characterized by 1H NMR, fast atom bombardment/mass spectrom...

• Global Rainfall erosivity increase on average 26.2–28.8% (2050) and 27–34.3% (2070). Use of 19 climate models three RCP scenarios (2.6, 4.5, 8.5) for 2050 2070. 80–85% global land surface will have an increasing trend in rainfall erosivity. Large projected changes are expected the Northern Hemisphere. Climate change drive high erosion rates. The erosive force (rainfall erosivity) is a major d...

This paper presents a theoretical framework, which has been adopted in designing an on-line multi-player strategy game Europe 2045. Europe 2045 is an educational tool for high school social science courses, aimed at familiarizing students with political, economic, and social issues in contemporary Europe. Apart from learning facts, players develop a range of key skills: discussion ability, nego...

One of the major factors, contributing to the emission of greenhouse gases in the environment is generation of pollutant gases in municipal landfills. As for the design and building of a gas collecting system, it is necessary to properly estimate the amount and type of the landfill emissions. By means of LandGEM model, this study predicts the amount and type of the landfill gases, produced for ...
