2. 1. Extreme environments - Design and human factors considerations

   Author : Olga Bannova; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extreme environments; Engineering; Engineer; Architect; Design Planning; Architecture; Multidisciplinary and Trans-disciplinary Design and Planning; Human Factors;

   Abstract : The starting point of this research is based on my experience at SICSA performing research and design for extreme environments, including orbital and lunar planetary facilities, disaster shelters, polar stations and offshore surface and submersible habitats. This thesis explores what aspects and issues of design and planning processes in extreme environments have to be addressed in a similar way and therefore may be used as a basis for further work toward PhD thesis to develop a methodological planning tool or matrix.

   Abstract : The dramatic change in properties of water near its critical point (i.e. T = 374 °C and p = 22.1 MPa, note: 100 MPa = 0. READ MORE

5. 3. Designing for Extremes

   Author : Olga Bannova; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; Architect; Human Factors; Engineering; Engineer; Multidisciplinary and Trans-disciplinary Design and Planning.; Extreme environments; Architecture; Design Planning;

   Abstract : The starting point of this research is based on personal experience in research and design for extreme environments, including orbital and lunar planetary facilities, disaster shelters, polar stations and offshore surface and submersible habitats. This work reflects on related to research problem technical papers, discussions with professionals about their work experience with projects in extreme conditions, and students' workshops debating strategies to form sustainable behavior and design practices.

6. 4. Growth and survival of Acidithiobacilli in Acidic, metal rich environments

   Author : Stefanie Mangold; Mark Dopson; Axel Schippers; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Acidithiobacilli are acidophilic microorganisms that play important roles in many natural processes such as acidification of the environment, influencing metal mobility, and impacting on global sulfur and iron cycles. Due to their distinct metabolic properties they can be applied in the industrial extraction of valuable metals. READ MORE

7. 5. Coastal signals of environmental changes: foraminifera as benthic monitors

   Author : Inda Brinkmann; Kvartärgeologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; benthic foraminifera; proxy calibration; trace element geochemistry; environmental DNA; deoxygenation; drought; coastal environments;

   Abstract : Climate changes, tightly linked to anthropogenic activities, are significantly altering environments and ecosystems globally, such as by increasing marine and coastal deoxygenation or occurrences of extreme weather events. The significance of paleoenvironmental and -climate reconstructions, as well as monitoring of current conditions, for unravelling baseline natural variation, today’s changes and potential future impacts, has been recognised by the Intergovernmental Panel on Climate Change (IPCC) reports.
