متن کاملThe influence of suburban land use on habitat and biotic integrity of coastal Rhode Island streams.

By monitoring stream biotic communities in various geographic regions, we can better understand and conserve our watershed ecosystems. The objective of this study was to examine the relationship between watershed land use and the integrity of benthic inve...
متن کاملBoundary slopes (nearly) bound cyclic slopes
Let rm and rM be the least and greatest finite boundary slopes of a hyperbolic knot K in S . We show that any cyclic surgery slopes of K must lie in the interval (rm − 1/2, rM + 1/2). AMS Classification 57M25; 57M27
متن کاملDevelopment of a suburban catchment model within the LIQUID framework
The world-wide trend towards a growing urbanization mainly affects suburban areas. These areas are subject to rapid modifications such as an increase of impervious areas, concentration of runoff in sewer systems, river regulations, but also a decline of agricultural areas causing a forest increase. These changes have an impact on the local hydrology and can induce floods, pollution or decrease ...

Helga Kuhse and Peter Singer recently examined the view expressed by John Lorber that whereas at times it is permissible to allow severely handicapped infants to die, killing them must never be allowed. In attempting to demonstrate the mistaken nature of Lorber's fear that allowing active infanticide would lead us onto a slippery slope Kuhse and Singer make much use of John Harris's paper in th...
