1. 1. Studies in Glacier Mass Balance : Measurement and its errors

   Författare :Andrew Mercer; Peter Jansson; Gunhild Rosqvist; Ian Brown; Jonathan Carrivick; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glaciology; Mass Balance; Measurement Errors; Physical Geography; naturgeografi;

   Sammanfattning : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. LÄS MER

3. 2. Young today-adult tomorrow! Studies on physical status, physical activity, attitudes, and self-perception in children and adolescents

   Författare :Ann-Christin Sollerhed; Samhällsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical education; physical status; physical capacity; self-perception; attitudes; sense of coherence; Medicine human and vertebrates ; intervention; physical activity; adolescents; Young people; children; Medicin människa och djur ;

   Sammanfattning : The aim was to gain knowledge of young people's physical status and physical activity, and to further the understanding of the role of school physical education in a salutogenic public health perspective. Two studies were performed in southern Sweden. Study 1 was performed in 1996 among 301 adolescents aged 16-19 in upper secondary school. LÄS MER

4. 3. On the nature of self-assembly in low-density condensed matter : A classical molecular dynamics approach

   Författare :Alfredo Metere; Peter Oleynikov; Anatoly Belonoshko; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fysikalisk kemi; Physical Chemistry;

   Sammanfattning : The study of the physics of self-assembly in low-density condensed matter is an extremely interesting, mostly unexplored field of scientific research. The contribution reported in this thesis explains how this problem can be addressed using molecular dynamics simulation of 3D systems composed by simple, identical particles, interacting via a spherically symmetric pair potential, which belongs to the class of Dzugutov potentials.

5. 4. Palaeoglaciology of the northeastern Tibetan Plateau

   Författare :Jakob Heyman; Arjen P Stroeven; Clas Hättestrand; Helena Alexanderson; Frank Lehmkuhl; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tibetan Plateau; palaeoglaciology; Physical geography; Naturgeografi; Quaternary geology; Kvartärgeologi; Physical Geography; naturgeografi;

   Sammanfattning : This study concerns the palaeoglaciation of the northeastern Tibetan Plateau, with emphasis on the Bayan Har Shan (Shan = Mountain) in the headwaters of Huang He (Yellow River). To reconstruct past glacier development multiple techniques, including remote sensing, field investigations, cosmogenic exposure dating, and numerical modelling have been employed. LÄS MER

7. 5. Quantity and quality of soil organic matter in permafrost terrain

   Författare :Gustaf Hugelius; Peter Kuhry; Philip Wookey; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; carbon; soil organic matter; soil organic carbon; permafrost; arctic; upscaling; peat plateau; cryoturbation; active layer; thermokarst; carbon nitrogen ratio; stable isotopes; humification; Physical geography; Naturgeografi; geografi med naturgeografisk inriktning; Physical Geography;

   Sammanfattning : High latitude terrestrial ecosystems are considered key components in the global carbon (C) cycle and hold large reservoirs of soil organic carbon (SOC). Much of this is stored as soil organic matter (SOM) in permafrost soils and peat deposits and is vulnerable to remobilization under future global warming. LÄS MER
