1. 1. Industrial metabolism : The emerging landscape of heavy metal immission in Sweden

   Författare :Bo Bergbäck; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : Since the turn of this century, technological development has drastically increased the industrial consumption of toxic metals. Once dispersed in the environment, the metals cannot be degraded but will be accumulated in soil or sediment sinks. Thus, environmental effects of heavy metal pollution tend to be permanent. LÄS MER

4. 3. Structuring empirical knowledge on environmental issues : urban heavy metal metabolism

   Författare :Johan Hedbrant; Ulrik Lohm; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Föroreningsfrågor; metodik; tungmetaller; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : During the last century, there has been a large import of heavy metals to urban areas. Only a small fraction, about 10%, has reached the biosphere, the rest is still residing in various goods such as cables, construction materials, technical equipment and batteries, which are still in use or abandoned in infrastructure, buildings, households, enterprises and vehicles.

5. 4. Insights into the metabolism of Clostridium thermocellum for cellulosic ethanol production

   Författare :Johannes Yayo; Antonius J. A. van Maris; Richard Sparling; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Clostridium thermocellum; ethanol; glucose; fructose; amino acids; pyrophosphate; chaotropicity; thermodynamic driving force; laboratory evolution; chemostats; metabolic engineering; Biotechnology; Bioteknologi;

   Sammanfattning : The societal goal of reaching net-zero CO2 emissions requires development of integrated biorefineries to produce biomass-derived fuels and chemicals. For sustainable second-generation bioethanol production, consolidated bioprocessing with the thermophile Clostridium thermocellum is regarded as a promising concept in view of the microorganism’s native ability to efficiently degrade plant cell wall material.

7. 5. Torken : tvångsvården av alkoholmissbrukare i Sverige 1940-1981

   Författare :Johan Edman; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; alcoholic care institutions; compulsory care; gender; implementation; problem definitions; recommodification; social criticism; social problems; treatment of alcoholics; History subjects; Historieämnen;

   Sammanfattning : This dissertation investigates compulsory care of alcohol abusers in Sweden during the years 1940 to 1981. The purposes of the dissertation are twofold: in part to determine the concrete forms which care services for alcohol abusers took during the years focused on, in part to analyze what connections existed between the development of services and conceptions of the reasons for, consequences of and possible solutions to alcohol abuse.
