We analyze how extreme rainfall intensities in the Eastern United States depend on temperature T, dew point temperature Td, and convective available potential energy CAPE, in addition to geographic sub-region, season, and averaging duration. When using data for the entire year, rainfall intensity has a quasi Clausius-Clapeyron (CC) dependence on T, with super-CC slope in a limited temperature r...

Development of information technology in the field of spatial data processing has helped many digital mapping. In the present study, the authors will empower geographic information systems (GIS) for geographic data processing potential Banyuasin district. The potential of the region are agriculture, farming, and industry. The method used to develop the GIS is the waterfall approach models. Afte...

We estimated the geographic distributions of triatomine species in Central-West Region of Brazil (CW) and analysed the climatic factors influencing their occurrence. A total of 3,396 records of 27 triatomine species were analysed. Using the maximum entropy method, ecological niche models were produced for eight species occurring in at least 20 municipalities based on 13 climatic variables and e...

A mechanical spring-block model is used for realizing an objective space partition of settlements from a geographic territory in region-like structures. The method is based on the relaxation-dynamics of the spring-block system and reveals in a hierarchical manner region-like entities at different spatial scales. It takes into account in an elegant manner both the spatiality of the elements and ...

political geographic changes of the caspian region due to the independence of the states of the soviet :union: in 1991, has created changes in the geopolitical situation. iran and russia's policies in order to maintain and extend their dominance on the region, and the performance of azerbaijan, turkmenistan and kazakhstan in the field of economic progress, to achieve greater independence a...

In the United States, all previously reported cases of Rickettsia parkeri rickettsiosis have been linked to transmission by the Gulf Coast tick (Amblyomma maculatum). Here we describe 1 confirmed and 1 probable case of R. parkeri rickettsiosis acquired in a mountainous region of southern Arizona, well beyond the recognized geographic range of A. maculatum ticks. The likely vector for these 2 in...

To understand genetic variation and population dispersal in the Yangtze vole Microtus fortis calamorum distributed in the Dongting Lake region, 144 individuals were collected from six habitat patches. The mitochondrial DNA control region was sequenced and 17 haplotypes were observed. Of the six investigated populations, haplotype and nucleotide diversities of those from larger patches were high...

Variation of morphological characters in the pitviper Bothrops asper (Garman) was studied in terms of scutellation, color patterns, and landmark measures for 374 Middle American specimens. Gender, ontogeny, and geographic effects were examined for each character. In this species, females are larger than males and have more ventral and dorsal rows, and can be distinguished by some landmark varia...

OBJECTIVE To estimate the prevalence of risk factors for HIV infection among Mexican migrants and immigrants (MMIs) in different geographic contexts, including the sending communities in Mexico, the receiving communities in the United States (US), and the Mexican North border region. MATERIAL AND METHODS We conducted a probability survey among MMIs traveling through key border crossing sites ...
