Recently, the topic of border regions receives more and more attention from both academics and politicians. This article serves as an overview of some aspects of this topic, by focusing on reasons for current interest in border regions
The spatial formation of social and cultural worlds is a basic assumption of traditional geographical research. The ongoing globalization of local conditions is making this perspective more and more doubtful. - (IfL)
by SEM before and after the experiment. B. subtilis had a strong influence on granite weathering by forming pits. Plagioclase was more vulnerable to bacterial weathering than biotite among the granite composing minerals.
The AA. performed a comparative experiment to investigate : 1) how the ubiquitous soil bacterium Bacillus subtilis weathers granite; and 2) which granite-forming minerals weather more rapidly via biological processes. Granite surfaces were observed
Analysis of the problem of a balanced population composition in the great urban agglomerations. In the seventies there is a trend towards more one person households, more people with low incomes and a growing percentage of ethnic minorities
to topography and a dynamic geologic history. Many plant and animal species are found in only one watershed or are restricted to a narrow altitudinal belt. AA. want more parks and preserves, expansion of small preserves or their interconnection by conservation
corridors, and more efforts to control poaching and arson. - (SLD)
. He also indicates the possible best means not only of safeguarding the park, but also and more importantly of enhancing its value. He believes that opening it to tourists would be beneficial| the park would be better known, more readily accepted
Seven dates have been produced, using the 230Th/234U dating method on six samples of speleothems collected in a cave, recently discovered in Gaspésie. Ages obtained range between 102000 and 223000 years B. P. The absence of redissolution traces
in the calcite of the samples suggest that the cave was dewatered for more than 200000 years. This very old cave which seems to have survived more than one glacial period also contains a noticeable variety and quantity of bones, some of which covered with calcite
In Chicago, ethnic neighborhoods revolve around places of worship. As the ethnic composition of neighborhood changes over time, the sacred spaces may be shared by more than one ethnic group. Incoming ethnic groups also transform profane spaces
into sacred places. Paper includes case studies of the South Shore, West Englewood, Logan Square, Ravenswood, West Ridge, and Portage Park (Northwest Side). More dramatic changes (except for Catholic churches) were found in the first two cases of the South
Side and more sharing of sacred space was found in the three North Side cases. - (SLD)
The City of Calgary was only founded in 1884 but already had a population of more than 1 million in 2006. Due to rising oil prices and huge sand oil deposits in northern Alberta the economy is booming and more and more people are moving to Calgary
in their mass balance. Further, the more maritime Storsteinsfjellbreen does not seem to collect more snow during the winter than the more continental Storglaciären.
Sasaki generalizes the urban-growth control model developed by Bruekner and Lai, and concludes that the optimal urban-growth control is less (more) stringent than the B-L model when an agglomeration effect (public-good-provision effect
) is considered. The paper proves that the optimal urban-growth control may or may not be more stringent than the B-L model when the agglomeration effect or (and) the public-good-provision effect is (are) considered. This result sharply differs from
The AA. demonstrate that children who are born within 15 months of a preceding birth are much more likely than other children to die in the first two years of life, once the confounding effecs of prematurity are removed.
This paper reviews the eruption sequence and reexamines some of the more problematic and challenging volcanological aspects of the Krakatau event. Various hypotheses about the cause of the tsunamis and explosions are reviewed and it is concluded
