Dispersal barriers have demographic, evolutionary and ecosystem-wide consequences. With ongoing changes in the environment, it is likely that some dispersal barriers will disappear while others will appear, and it is crucial to understand these dynamics to forecast species distributions and adaptive potential. Here we review recent literature on the ecological and evolutionary aspects of dispersal

The purpose of this paper is to formulate an optimization model for the production scheduling problem at continuous production sites. The production scheduling activity should produce a monthly schedule that accounts for orders and forecasts of all products. The plan should be updated every day, with feedback on the actual production the previous day. The actual daily production may be lower than

The development of the European Higher Education Area (EHEA) is firmly rooted in the idea of higher education (HE) as the cornerstone of a knowledge-based society. Throughout Europe, HE bodies are addressing issues of quality, mobility, employability and lifelong learning. HE agencies and institutions alike are working hard to harmonise European degrees and apply quality assurance standards (ESG,

Popular Abstract in Swedish Salmonella infektion drabbar ca 16 miljoner människor i världen per år. Salmonella sprids genom mat och vatten och fšrekommer främst i länder där god hygien är ett problem. Beroende på vilken typ av Salmonella som man infekteras av, kan man drabbas av magsjuka eller en allvarlig systemisk infektion som i värsta fall kan leda till döden (tyfoid feber). Salmonella tar sigThe immune system has several strategies to combat infections. The present study investigates various aspects of the interaction between Gram negative bacteria, particularly Salmonella, and antigen presenting cells (APC). Salmonella is an intracellular bacterium infecting mice and man. Salmonella typhimurium infection in mice is a frequently used model for studying systemic Salmonella infection. O

Digitala system för pedagogisk bedömning öppnar nya möjligheter som inte finns med papper och penna. Dessutom frigörs tid för lärarna. Vi ber därför Skolverket att tillsätta en bred arbetsgrupp för att utveckla ett digitalt system för nationella prov, skriver Agneta Gulz och Magnus Haake, båda verksamma inom utbildningsvetenskap.

The paper treats encounters between Swedes and Germans within the framework of lodges and secret societies in Swedish-Pomerania during the 1760-ies.

This paper addresses the control problem of a specially designed nonlinear actuator intended for use in legged robots and other related mechatronic devices. Use of this drive could considerably increase energy efficiency and the time of autonomous robot operation. Nevertheless, the highly nonlinear model of the actuator and the unavailability of part of the state for measurement pose considerable
