1. 1. Dynamics of metal oxides surfaces and the connection to reactivity

   Författare :Micael Baudin; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; metal oxide surfaces; single crystal; molecular dynamics; dynamical effects onreactivity; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

   Sammanfattning : Many interesting chemical and physical phenomena which take place on surfaces of metaloxides rely on the material's ability to repeatedly alter the electronic surface structure. Formost metal oxides this functionality is connected to the degree of non-stoichiometry andthe presence of structural defects. LÄS MER

4. 3. Modeling Specialization and Division of Labor in Cultural Evolution

   Författare :Micael Ehn; Eriksson Kimmo; Thomas Mark; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Specialization; Division of Labor; Cultural Evolution; Mathematics Applied Mathematics; matematik tillämpad matematik;

   Sammanfattning : Division of labor and division of knowledge are so important and common in society today that it is difficult to imagine a functional society where everyone knows the same things and performs the same tasks. In such a society everyone grows, or gathers, and prepares their own food, makes their own tools, builds their own house, and so on. LÄS MER

5. 4. Land degradation and mitigation in northern China. Evaluated from the biological production

   Författare :Micael Runnström; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; marklära; geomorfologi; Fysisk geografi; climatology; kartografi; klimatologi; cartography; pedology; desertification; China; GPP; Mu Us; LUE-model; overgrazing; Physical geography; geomorphology;

   Sammanfattning : Land degradation is commonly perceived to be severe in many parts of semi arid China. The transition towards market economy since the 1978 reforms, have set marginal dry lands under added pressure in the form of increased livestock numbers and expanding cultivation on erosive soils.

7. 5. Adhesion to machined and laser ablated wood surfaces

   Författare :Micael Stehr; KTH; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; ablation; adhesion; checks; coating; cracks; excimer laser; gluing; IR laser; mechanical machining; mechanical weak boundary layer; microscopy; notched specimens; pine; planing; sample preparation; sawing; scanning electronmicroscopy; spruce; tip-cracks; UV laser; weak boundary layer; wood;

   Sammanfattning : This thesis is a contribution to the R&D-program ValueActivation at KTH,Division of Wood Technology and Processingand containsfive papers related to the evaluation and development ofmachining techniques (mechanical and irradiation treatments)whereby weak boundaries at the wood surfaces in the form of(mechanical) weak boundary layers and (micro) cracks due tomechanical treatment can be avoided.The first paper describes the development of a method–using a UV laser–to study the mechanically weakenedboundaries.
