Nutrient spiraling in theory and application provides a framework for comparing nutrient retention efficiency of urban streams to relatively unaltered streams. Previous research indicated that streams of the southwestern USA deserts are highly retentive of N because of N limitation, high productivity, and high channel complexity (in particular, extensive transient storage associated with the hy...

Sustainability increasingly becomes an effective argument in the public and academic discourse. However, in the scientific design process of IT artifacts, the notion of sustainability is often misused. IT artifacts and consequences resulting from their operation are characterized to be sustainable without truly reflecting the meaning of the characteristics of sustainability. By subscribing to a...

The impact of riparian land use on the stream insect communities was studied at Kudremukh National Park located within Western Ghats, a tropical biodiversity hotspot in India. The diversity and community composition of stream insects varied across streams with different riparian land use types. The rarefied family and generic richness was highest in streams with natural semi evergreen forests a...

A K-matrix re-analysis of the Kπ S-wave is performed in the mass region 900− 2100 MeV, and solutions which describe the data well are found. The solution with two resonances in the (IJP = 1 20 +)-wave has poles at (1415 ± 25)i(165 ± 25) MeV and (1820 ± 40) -i(125 ± 50) MeV, close to the previous result of D. Aston et al., Nucl.Phys., B296 (1988) 493. The corresponding bare states, which are the...

We present an innovative backup and restore solution, called LifeBoat, for Windows machines. Our solution provides for local and remote backups and ‘‘bare metal’’ restores. Classic backup systems do a file system backup and require the machine to be installed before the system can be restored or they do a block for block backup of the system image which allows for a ‘‘bare metal’’ restore, but ...

Streams, as low-lying points in the landscape, are strongly influenced by the stormwaters, pollutants, and warming that characterize catchment urbanization. River restoration projects are an increasingly popular method for mitigating urban insults. Despite the growing frequency and high expense of urban stream restoration projects, very few projects have been evaluated to determine whether they...

In dry climate zones, headwater streams are often regulated for water extraction causing intermittency in perennial streams and prolonged drying in intermittent streams. Regulation thereby reduces aquatic habitat downstream of weirs that also form barriers to migration by stream fauna. Environmental flow releases may restore streamflow in rivers, but are rarely applied to headwaters. We sampled...

STINA GUSTAFSSON H aitat om pesation in nare-like fshw ys The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams, but these fishways also have the potential to compensate for habitat degradation and loss associated with hydropower. The habitat potential of fishways has largely been overlooked, and therefore the aim of t...
