The Kelkit Valley is geographically a transitional zone between the Middle Black Sea and Inner Anatolia regions in Turkey. Two new species of Macrochelidae are described from this area--Longicheles ozkani sp. nov. and Longicheles ayyildizi sp. nov. Longicheles lagrecai (Valle, 1963) is recorded for the Turkish fauna and redescribed on the basis of specimens collected from the Valley. A world-wi...

Sixty-seven isolates of Phytophthora infestans collected from Himalayan hill regions and subtropical planes of India were characterized by RAPD markers to assess diversity and differentiation based on location of origin. Ten random decamer primers generated 161 polymorphic fragments. Association of P. infestans isolates on the dendrogram and PCO plot revealed two clear grouping based on geograp...

Continental Antarctic is perceived as a largely pristine environment, although certain localized regions (e.g., parts of the Ross Dependency Dry Valleys) are relatively heavy impacted by human activities. The procedures imposed on Antarctic field parties for the handling and disposal of both solid and liquid wastes are designed to minimise eutrofication and contamination (particularly by human ...

In this work we have investigated the behaviour of the fast consistency algorithm for the propagation of changes in a set of replicas with multiple zones with high read demand. We demonstrate that the algorithm does not perform well in regions with a more than one valley of high demand surrounded by lower demand. The situation is characterized and a potential solution to change the distribution...

Valley networks, concentrations of dendritic channels that often suggest widespread pluvial and fluvial activity, have been cited as indicators that the climate of Mars differed significantly in the past from the present hyperarid cold desert conditions. Some researchers suggest that the change in climate was abrupt, while others favor a much more gradual transition. Thus, the precise timing of...

In this paper, uego, a new general technique for accelerating and/or parallelizing existing search methods is suggested. The skeleton of the algorithm is a parallel hill climber. The separate hill climbers work in restricted search regions (or clusters) of the search space. The volume of the clusters decreases as the search proceeds which results in a cooling effect similar to simulated anneali...
