1. Large organic aerosols in a human exposure chamber : applications in occupational dermatology and lung medicine
Sammanfattning : Exposure to large organic aerosol particles may cause respiratory and skin reactions. The use of human exposure chambers offers possibilities for experimental exposure challenges carried out with patients, in research and for investigations of the effects of exposure on the skin and in the respiratory tract.

2. Aspects of interferon alpha signalling in hematopoetic cells
Sammanfattning : The type I interferons (IFN) are a family of cytokines with pleiothropic activities that include inhibition of viral replication, cell proliferation and activation of the immune system. These properties give the IFNs important physiological and pathological roles in infection and cancer and have led to their therapeutic use for many clinical conditions. LÄS MER
3. Rotavirus Disease Mechanisms Diarrhea, Vomiting and Inflammation : How and Why
Sammanfattning : Rotavirus infections cause diarrhea and vomiting that can lead to severe dehydration. Despite extensive tissue damage and cell death, the inflammatory response is very limited. LÄS MER
4. Anchorage in Concrete Structures : Numerical and Experimental Evaluations of Load-Carrying Capacity of Cast-in-Place Headed Anchors and Post-Installed Adhesive Anchors
Sammanfattning : Various anchorage systems including both cast-in-place and post-installed anchors have been developed for fastening both non-structural and structural components to concrete structures. The need for increased flexibility in the design of new structures and strengthening of existing concrete structures has led to increased use of various metallic anchors in practice. LÄS MER
5. A Traffic Simulation Modeling Framework for Rural Highways
Sammanfattning : Models based on micro-simulation of traffic flows have proven to be useful tools in the study of various traffic systems. Today, there is a wealth of traffic microsimulation models developed for freeway and urban street networks. The road mileage is however in many countries dominated by rural highways. LÄS MER
