1. 1. Understanding as experiencing a pattern

   Författare :Paulina Lindström; Kognitionsvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; Understanding; eye-tracking; mathematical problem solving; cognition; pedagogy;

   Sammanfattning : The thesis proposes that understanding is a matter of experiencing a pattern. To experience a pattern involves seeing how a task, principle, or problem space is structured; to attend to the relevant information; and to be able to use that information as it relates to the knowledge domain at hand.

3. 2. Biomedical and atmospheric applications of optical spectroscopy in scattering media

   Författare :Johannes Swartling; Atomfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Turbid media; Tissue optics; Tissue optical properties; Multiple scattering; Radiative transfer; Diffusion equation; Monte Carlo method; Time-resolved spectroscopy; Atomic and molecular physics; Integrating spheres; Atom- och molekylärfysik; Fysicumarkivet A:2002:Swartling;

   Sammanfattning : Spectroscopic analysis of scattering media is difficult because the effective path length of the light is non-trivial to predict when photons are scattered many times. The main area of research for such conditions is biological tissues, which scatter light because of variations of the refractive index on the cellular level. LÄS MER

4. 3. HIV-2 infection in Guinea-Bissau, West Africa, with special reference to clinical, immunological and epidemiological aspects

   Författare :Hans Norrgren; Sektion III; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infections; Africa; Guinea-Bissau; AIDS; HIV-1; HIV-2; Infektioner;

   Sammanfattning : We have followed a cohort of police officers in Guinea-Bissau between 1990 and 1997 for the study of clinical, immunological and epidemiological aspects of HIV-2 infection. Initially the prevalence of HIV-2 was high (11.6 %) and HIV-1 infection was rare (0. LÄS MER

5. 4. Aspects of Sorption Processes in Thermosiphon and in Falling Film Arrangements

   Författare :Henrik Kockum; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mass transfer; turbulence; falling film; heat transfer; entropy generation; pressure drop; restriction; friction; void fraction; two-phase flow; thermosiphon; sorption; heat pump; model; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

   Sammanfattning : A study concerning closure relations pertinent to the design of sorption equipment of absorption heat pumps has been undertaken. Specifically, thermosiphon and vertical falling film arrangements were studied. LÄS MER

7. 5. Understanding Weather effects on, in, and from large Herbivore Population Dynamics

   Författare :Lena Månsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; monitoring; management; data collection; Ecology; Ekologi; indirect effects; vegetation; modeling; time series analysis; precipitation; weather; population dynamics; Large herbivores;

   Sammanfattning : Large herbivores are monitored for various reasons in many areas around the world. Data from such monitoring can be of varying degree of detail and extent. Several studies have shown that we need extensive amounts of data with a high degree of detail to be able to understand anything from it. LÄS MER
