Information on important source areas for dissolved solids in streams of the southwestern United States, the relative share of deliveries of dissolved solids to streams from natural and human sources, and the potential for salt accumulation in soil or groundwater was developed using a SPAtially Referenced Regressions On Watershed attributes model. Predicted area-normalized reach-catchment deliv...

In this paper, we outline the relation between Knowledge Management (KM) as an application area on the one hand, and software agents as a basic technology for supporting KM on the other. We start by presenting characteristics of KM which account for some drawbacks of today’s – typically centralized – technological approaches for KM. We argue that the basic features of agents (social ability, au...

Damavand volcano is located 60 km to the East North- East of Tehran. It is a dormant stratovolcano outcrop in the Alborz Mountains of northern Iran and is the highest mountain (5670 m) in the Middle East and West Asia. Mazandaran Province, one of the most populous provinces by population density, Semnan and Gorgan provinces further east are neighbours of the Damavand. Volcanism in Damavand goes...

S U M M A R Y The dramatic asymmetry in terms of surface elevation, Cenozoic volcanisms and earthquake activity across the Red Sea is an enigmatic issue in global tectonics, partially due to the unavailability of broad-band seismic data on the African Plate adjacent to the Red Sea. Here, we report the first comprehensive image of the mantle transition zone (MTZ) discontinuities using data from ...

Using the Advanced Microwave Scanning Radiometer sensor (AMSR-E), winter (October to May) sea ice area flux is estimated for the main channels of the Canadian Arctic Archipelago, Baffin Bay and Fram Strait. The transport through Fram Strait is estimated at 533,000 km 2 and 635,000 km 2 for the winter of 2002/03 and 2003/04 which is below the 24-year average of 754,000 km 2 obtained by Kwok et a...

Organizations are pursuing the outsourcing of business processes (BPO) to offshore locations. However, current research has shown that an organizational learning gap between the client and vendor organizations leads to less than expected benefits. While networking and other distributed technologies provide a foundation for outsourcing, knowledge management (KM) can be used to bridge these gaps ...

Tongyu County in Northeast China is highly prone to land degradation due to its fragile physical settings characterized by a flat topography, a semi-arid climate, and a shallow groundwater table. This study aims to determine the causes of land degradation through detecting the long-term trend of land cover changes. Degraded lands were mapped from satellite images recorded in 1992 and 2002. Thes...
