An increased use of the Internet has created new business opportunities. The development of e-commerce has, however, been crippled by a limited understanding of logistics and customer needs. This paper sets out to highlight those issues in pharmaceutical retail where added services should be created through e-commerce. The research is based upon a case study covering the pharmaceutical system in S

Water harvesting and artificial recharge have been the main and parsimonious solution for water scarcity problems in the arid and semiarid Middle East for thousands of years. These techniques are increasingly being encouraged and at present there has been a renewed interest to find improved methods for water harvesting and artificial recharge in many arid countries. In the present study water bala

Statens utlåningsränta till nyföretagare borde vara lägre än hos en traditionell bank. Räntan bör sättas med hänsyn tagen till den samhällsnytta som en finansiering innebär, skriver professor Lars Oxelheim och doktorand Pontus Engström.

Water and salt mass balances for the Dead Sea were modeled. Precipitation, evaporation, river discharges, ground water flows, input/output from potash companies and salt production, and brine discharge were included in the models. The mixing time in the Dead Sea was modeled using a single-layer (well-mixed) a two-layer (stratified) system. Using the single-layer approach the water level was predi

We investigate the propagation of electromagnetic waves in a waveguide filled with a nonlinear material. The electromagnetic field is expanded in the usual eigenmodes of the waveguide, and the coupling between the modes is quanti fied. We derive the wave equations governing each mode, with special emphasis on the situation with a dominant TE-mode. The result is a strictly hyperbolic system of nonline
