1. 41. Unifying first-principles and model approaches for strongly correlated materials : Interplay between long- and short-range correlations

   Författare :Fredrik Nilsson; Matematisk fysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; first-principle methods; strongly correlated materials; GW approximation; cRPA; random-phase approximation; dynamical mean-field theory; GW DMFT; downfolding;

   Sammanfattning : In materials with open 3$d$ and 4$f$ shells the valence electrons are relatively localized around the atoms which leads to large electron-electron correlations. These, so called strongly correlated materials, exhibit many intriguing properties such as high $T_c$ superconductivity, colossal magneto-resistance and heavy fermion behaviour. LÄS MER

3. 42. Cereal Dietary Fibre - Physicochemical Properties and Suitability for Addition to Low-Fat Meat Products

   Författare :Karin Petersson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dietary fibre; cereals; oat bran; rye bran; wheat bran; barley fibre; hydrolytic enzymes; physicochemical properties; low-fat sausages; low-fat meatballs; sensory perception; texture;

   Sammanfattning : It is well known that dietary fibre is good for the health. Cereals, and in particular the outer parts of the cereal kernels, are rich in dietary fibre. Rye bran, wheat bran, oat bran and barley fibre have been investigated regarding their suitability as additives in low-fat meat products. LÄS MER

4. 43. Video assisted gastrostomy in children

   Författare :Torbjörn Backman; Lund Pediatrik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Gastrostomy; Laparoscopy; VAG; Complications; VPS; Malignancy; Vomiting; Double U-stitch suture;

   Sammanfattning : Children with severe diseases can be provided nutritional support through a gastrostomy if needed. At the Department of Paediatric Surgery in Lund we have used the Video Assisted Gastrostomy (VAG) procedure since 1994 when establishing gastrostomies. LÄS MER

5. 44. Effects of nitrogen deposition on the growth, metabolism and activity of ectomycorrhizal fungi

   Författare :Magnus Ellström; MEMEG; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nitrogen deposition; Ectomycorrhizal fungi; Symbiosis; SOM modification; Carbon starvation; Metabolism; Nitrogen leakage; IR-spectroscopy; Mesh bags; Microarray; Axenic growth; Transcriptomics.;

   Sammanfattning : Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. LÄS MER

7. 45. Leaf Area Index of Scandinavian Forests Methods Using in situ and Remotely Sensed Data

   Författare :Helena Eriksson; Institutionen för naturgeografi och ekosystemvetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Geologi; fysisk geografi; Physical geography; geomorphology; Geology; physical geography; leaf aggregation; specific leaf area SLA .; Växtekologi; Plant ecology; Leaf area index LAI ; canopy reflectance models; spectral vegetation indices; remote sensing; pedology; cartography; climatology; Fysisk geografi; geomorfologi; marklära; kartografi; klimatologi;

   Sammanfattning : This thesis deals with methods of obtaining the leaf area index (LAI) from remotely sensed satellite data. Initially, in situ estimation methods were investigated, since the accuracy of the remotely sensed estimates is dependent on the quality of these estimates. LÄS MER
