1. 21. Ecosystem services in agricultural landscapes : A study on farming and farmers in South Africa and Sweden

   Författare :Rebecka Malinga; Regina Lindborg; Line Gordon; Thomas Elmqvist; Tobias Plieninger; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ecosystem service bundles; multifunctional landscapes; ecosystem service supply and demand; spatial scales; trade-offs; sustainable agriculture; transdisciplinary; stakeholder participation; Sustainability Science; vetenskap om hållbar utveckling;

   Sammanfattning : Humanity is facing challenges of sustainably producing enough food for a growing population without further eroding the world’s ecosystems. Transformation of natural habitats into agriculture has resulted in opportunities for civilization, but has also led to land degradation and loss of biodiversity, threatening the generation of ecosystem services.

3. 22. Stroke in geriatric patients - Aspects of depression, cognition and motor activity

   Författare :Berit Agrell; Geriatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stroke; laterality; rating scales; motoractivity; aphasia; neglect; disability; depression; cognition; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : Six depression rating scales, GDS, Zung, CES-D, CPRS-D and Cornell, were compared in 40 patients. The validity was good for all scales except for the Cornell scale. A comprehensive investigation was done in 116 elderly stroke patients. There was no difference in prevalence and severity of post-stroke depression in relation to side of lesion. LÄS MER

4. 23. Prediction, modeling, and refinement of protein structure

   Författare :Per Larsson; Arne Elofsson; Erik Lindahl; Barry Honig; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein structure prediction; Multiple alignments; Quality assessment; Molecular dynamics; Implicit solvent; Refinement; Bioinformatics; Bioinformatik; Bioinformatics; Bioinformatik; Statistical mechanics; Statistisk mekanik; Biochemistry; biokemi;

   Sammanfattning : Accurate predictions of protein structure are important for understanding many processes in cells. The interactions that govern protein folding and structure are complex, and still far from completely understood. However, progress is being made in many areas. Here, efforts to improve the overall quality of protein structure models are described. LÄS MER

5. 24. Superimposition of Contractional Structures in Models and Nature

   Författare :Hongling Deng; Hemin Koyi; Sudipta Sengupta; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; superimposition; progressive deformation; multiple phases; coaxial; non-coaxial; analogue modelling; fold-and-thrust belts; Geovetenskap med inriktning mot mineralogi; petrologi och tektonik; Earth Science with specialization in Mineral Chemistry; Petrology and Tectonics;

   Sammanfattning : Superimposition of contractional structures is widely observed in different scales in the world. Superimposed structures form due to different processes: change in strain accommodation from one type of structure to another during a single progressive shortening; successive coaxial shortening phases separated by an unconformity; superimposition of different non-coaxial shortening phases.

7. 25. An Optimisation Approach to Cartographic Generalisation

   Författare :Lars Harrie; Centrum för geografiska informationssystem (GIS-centrum); []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; incremental generalisation; multiple representation; least-squares method; optimisation; cartographic constraints; displacement; cartographic generalisation; graphic generalisation; map production; object-oriented spatial databases; Physical geography; geomorphology; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi; Technological sciences; Teknik;

   Sammanfattning : Cartographic generalisation is the process of simplifying a representation to suit the scale and purpose of a map. As such, generalisation has always been a central part in map production. This thesis is a contribution to the ongoing work on automating cartographic generalisation. LÄS MER
