1. 11. Meteoric Aerosols in the Middle Atmosphere

   Författare :Linda Megner; Jörg Gumbel; Martin Ridal; Gary E. Thomas; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; meteoroid; meteor; nucleation; mesosphere; stratosphere; ablation; smoke; NLC; PMSE; PSC; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; atmosfärvetenskap; Atmospheric Sciences;

   Sammanfattning : This thesis concerns the fate of the meteoric smoke in the Middle Atmosphere, and its effect on ice phenomena such as noctilucent clouds (NLC) and polar stratospheric clouds (PSC). The potential role of NLC as tracer for mesospheric processes and variability, and as a tool for monitoring this remote and inaccessible region, has generated substantial interest within the scientific community.

3. 12. Variability and feedbacks in the middle atmosphere

   Författare :Maartje Kuilman; Bodil Karlsson; Qiong Zhang; Hauke Schmidt; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Middle atmosphere dynamics; noctilucent clouds; solar cycle effects; climate feedbacks; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

   Sammanfattning : The importance of the middle atmosphere for the weather and climate on Earth is increasingly realized. Variability and feedback processes in the middle atmosphere need to be better understood and form the subject of this thesis. LÄS MER

4. 13. Environmental Atmosphere: Outdoor Environmental Assessments for Design and Education

   Författare :Lisa Tucker Cross; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Landskapsarkitektur; Landscape design; POE; outdoor environment; housing exhibitions; housing environments; expert checklist; environmental atmosphere; architectural education; cross-cultural; Physical planning; Fysisk planering;

   Sammanfattning : The primary goal of this thesis was to develop an Expert checklist for assessing and de-veloping outdoor residential environments. The checklist was utilized by 5 experts in the fields of architecture, landscape architecture, and urban planning who were all fa-miliar with the concept of architectural psychology. LÄS MER

5. 14. Quality Aspects of Modified Atmosphere Packaged Broccoli

   Författare :Annelie Jacobsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; heat transfer; mass transport; quality; flavour; aroma; modified atmosphere packaging; broccoli;

   Sammanfattning : The modified atmosphere packaging (MAP) of vegetables is used with the aim of prolonging the shelf-life of the packaged produce. The packaging material consists of a permeable film and as a result of the respiration of the produce and gas diffusion through the film, the O2 decreases and the CO2 increases inside the package.

7. 15. Modelling the middle atmosphere and its sensitivity to climate change

   Författare :Andreas Jonsson; Jörg Gumbel; Joanna Haigh; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; middle atmosphere; ozone; carbon dioxide; stratosphere; mesosphere; chemical kinetics; atmospheric tides; Meteorology; Meteorologi;

   Sammanfattning : The Earth's middle atmosphere at about 10-100 km has shown a substantial sensitivity to human activities. First, the ozone layer has been reduced since the the early 1980s due to man-made emissions of halogenated hydrocarbons. LÄS MER
