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

    Author : Olga Bannova; [2014]
    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.

  2. 2. Exhaled nitric oxide in extreme environments

    University dissertation from Stockholm : Karolinska Institutet, Department of Physiology and Pharmacology

    Author : Tryggve Hemmingsson; Karolinska Institutet.; Karolinska Institutet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exhaled nitric oxide; hand-held instrument; electrochemical detector; microgravity; International Space Station; high altitude; hypobaric hypoxia; normobaric hypoxia; backdiffusion;

    Abstract : Exhaled nitric oxide (NO) is a useful marker for lower airway inflammation. Since NO was found to be a component of an exhaled breath in the early 1990´s, the Fractional Exhaled Nitric Oxide (FENO 50) measurement is now well accepted among clinicians as a complementary test in the management of asthma.

  3. 3. Adjusting to the extreme Thermal adaptation in a freshwater gastropod

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magnus Johansson; Laurila Anssi; Robby Stoks; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radix balthica; Lake Mývatn; geothermal springs; thermal adaptation; isolation by environment; population structure; gene flow; cogradient variation; AFLP; thermal preference; CTmax; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Abstract : Temperature is a ubiquitous force influencing biological processes ranging from cellular responses to life span. The thermal environment for many organisms is predicted to change with globally increasing temperatures and studies conducted in natural systems incorporating various evolutionary forces, such as gene flow, is needed.

  4. 4. Non-Perturbative Quantum Field Theory in Extreme Environments

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Per Liljenberg; [1996]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; pair production; Bose-Einstein condensation; functional representation; Schwinger model; external field; boson stars; temperature; magnetisation;

    Abstract : The aim of this thesis is to describe some physical systems which can be treated by non-perturbative methods in quantum field theory. In the thesis we study systems described by quadratic Hamiltonians, possibly extended with an external electromagnetic field and/or with a thermal heat bath. READ MORE

  5. 5. Analysis of Secondary Metabolites from Aspergillus fumigatus and Penicillium nalgiovense Antimicrobial Compounds from Filamentous Fungi Isolated from Extreme Environments

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Stefan Svahn; Lars Bohlin; Björn Olsen; Ulf Göransson; Erja Chryssanthou; Douglas Kinghorn; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aspergillus fumigatus; Penicillium nalgiovense; secondary metabolites; invasive aspergillosis; elicitation; gliotoxin; bis methyl gliotoxin; amphotericin B; Pharmacognosy; Farmakognosi;

    Abstract : This thesis describes the cultivation and extraction of filamentous fungi isolated from extreme environments in the search for new antibiotic compounds. Filamentous fungi are a rich source of medicines including antibiotics, and it is believed that many currently unknown fungal species and bioactive fungal metabolites remain to be discovered.
