Improved mortality after STEMI over two decades
Results A total of 335 patients in 1986, 351 in 1996 and 178 patients in 2006 comprise the total study population of 864 STEMI patients. In addition 25 (6,9%) patients died within the first 24 hours of hospital admission in 1986, 33(15,6%) in 1996 and 5 (2,7%) in 2006. One-year mortality decreased from 26.3% in 1986 and 19.7% in 1996 to 12.9% in 2006 (p = 0.001). Cox proportional hazard analysi...
متن کاملFour decades of change: dramatic loss of zoobenthos in an oligotrophic lake exhibiting gradual eutrophication
Native species in lakes commonly are affected by cultural eutrophication and introductions of nonnative species. The effects of these disturbances on benthic communities in large lakes have been understudied, despite the integral role that benthos play in maintaining habitat complexity and ecosystem processes. Lake Tahoe has experienced progressive eutrophication and introductions of nonnative ...

15 صفحه اولOptimum water depth ranges of dominant submersed macrophytes in a natural freshwater lake
Macrophytes show a zonal distribution along the lake littoral zone because of their specific preferred water depths while the optimum growth water depths of dominant submersed macrophytes in natural lakes are not well known. We studied the seasonal biomass and frequency patterns of dominant and companion submersed macrophytes along the water depth gradient in Lake Erhai in 2013. The results sho...
متن کاملWater Constituents and Water Depth Retrieval from Sentinel-2A - A First Evaluation in an Oligotrophic Lake
Satellite remote sensing may assist in meeting the needs of lake monitoring. In this study, we aim to evaluate the potential of Sentinel-2 to assess and monitor water constituents and bottom characteristics of lakes at spatio-temporal synoptic scales. In a field campaign at Lake Starnberg, Germany, we collected validation data concurrently to a Sentinel-2A (S2-A) overpass. We compared the resul...
