1. Cadmium induced kidney dysfunction in rodents and its relevance to biomonitoring : experimental and environmental findings
Sammanfattning : This study deals with how workers actively introduced a new technique to their own labour process. More specifically, it is concerned with how Swedish forest workers during the 1950s gradually replaced the manual one-man crosscut saw with the motor-driven saw. LÄS MER
2. Reproductive toxicology of endocrine disruptors : effects of cadmium, phthalates and phytoestrogens on testicular steroidogenesis
Sammanfattning : A number of investigations during the last two decades describe adverse trends in male reproductive health, which have been proposed to be caused by environmental factors with endocrine disrupting properties. In contrast to many other toxicants, endocrine disruptors often do not show linear dose-response relationships typical of those found in traditional toxicological studies. LÄS MER
3. Hazard screening of contaminated sites : bioavailable fractions and biological in vitro tools
Sammanfattning : The environmental bioavailability of contaminants, rather than their total concentrations in the soil compartment play a decisive role for the risks associated with contaminated sites. Various soil constituents and abiotic conditions have strong influence on bioavailability, which may vary substantially between different locations. LÄS MER
4. Development of an Environment-Accident Index : A planning tool to protect the environment in case of a chemical spill
Sammanfattning : The increasing mass and complexity of chemicals being produced and transported has resulted in more rigorous demands on both authorities as well as chemical-handling industries to assess the risks involved. The Environment-Accident Index (EAI), has been proposed as a planning tool created as an equation in which chemical properties (variables describing the chemical involved) are combined with site-specific properties (variables describing the accident site).

5. Simulation-based Evaluation of Fixed to Flexible Transit
Sammanfattning : Emerging technologies have inspired a wide array of flexible public transit system designs characterized by varying degrees of demand-responsive routing and scheduling. The availability and synthesis of new data sources with higher degrees of spatial and temporal richness brought on by advancements in Intelligent Transport Systems allow for monitoring and responding to evolving supply-demand imbalances in real-time.
