Correspondence analysis was applied to sand fly sampling in 865 stations from the Western Mediterranean basin. The position of each of 24 species was determined with respect to the bioclimatic belts. Thus, the multidimensional analyses manifest clear correlations between bioclimatic belts and their expression in the area, the phytosociological groupings, and vector species of visceral and cutan...

Several studies in literature have investigated the performance of the proposed IEEE 802.11E standard for QoS differentiation in WLAN, but most of them are limited both with respect to the range of the parameter settings and the considered traffic scenarios. The aim of the present study is twofold. First, we systematically investigate the differentiating capabilities of QoS mechanisms. Second, ...

The role of facilities and associated services for amphibians has recently undergone diversification. Amphibians traditionally used as research models adjust well to captivity and thrive with established husbandry techniques. However, it is now necessary to maintain hundreds of novel amphibian species in captive breeding, conservation research, and biomedical research programs. These diverse sp...

Central and Southern Africa are generally regarded as being endemic areas for African horse sickness (AHS). With the advent of the concepts of risk analysis and regionalisation/zoning, however, the possibility has now arisen of establishing 'zones' within South Africa for AHS surveillance purposes. In 1993, a protocol was submitted to the European Community (now European Union: EU), proposing t...

the effect of underground cavities in site seismic response was studied over the subway tunnels that are under construction in the city of karaj, using ambient noise measurements as well as numerical modeling. the idea for this research comes from the observation of differences in experimental site transfer function, calculated on more than 100 locations of the city, for the areas near the unde...
