Popular Abstract in Swedish Skogen utgör en viktig del av kolbalansen mellan mark och luft och har en potential att reducera koncentrationen av koldioxid i atmosfären. Mängden bladyta i en skog ger en indikation på skogens förmåga att binda koldioxid till marken. Den här avhandlingen utforskar möjligheterna att erhålla information om skogars mängd av bladyta med hjälp av den information som registThis 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. The results of the present studies indicate that some methods commonly used as a reference for more complicated methods could result in

The effect of harvest time and storage on dietary fibre content and composition was investigated in six cultivars of white cabbage (Brassica oleracea var capitata). Three cultivars were of early maturity type (SW Nordpol, Rolly and Balbro) and three of late maturity type (Predikant, Hanna and Lion). The average total dietary fibre (TDF) content was 241 g kg(-1) dry matter (DM) (CV = 13), of which

Lymfödem är ett kroniskt sjukdomstillstånd som påverkar individens livstillfredsställelse och arbetsförmåga. Basen för all lymfödembehandling är ständig kompression, och behandlingen ska vara kontinuerlig. Patienterna bör bedömas och behandlas av ett multiprofessionellt team. Konservativ behandling innebär adekvat information till patienten, förebyggande åtgärder, kompression med strumpa och vid b

Popular Abstract in Swedish Denna avhandling söker visa att psykoanalysen slagit in en bärande vägg i sin egen teori genom att avfärda det psykiska energibegreppet. Eftersom överbringande av information kräver energi (Brillouin) hamnar vi förutan ett psykiskt energibegrepp i epifenomenalism och cartesiansk dualism. Därmed skulle Darwin s a s ställas utanför psykologin. Psykisk energi kan också visThis thesis purports to prove the logical necessity of the psychic energy concept discarded by modern psychoanalysis by linking the "evolutionistic argument" against epiphenomenalism to Brillouin´s negentropy principle. If our conscious awareness of affects and other psychological events should be attributed a signal value at all, they must necessarily exercise effect on the soma. This presupposes

The importance of patterns of daily occupations to health has been emphasised ever since occupational therapy was founded, but little is known about this relationship. The aim of this study was to describe in detail one woman’s pattern of daily occupations as an initial step in developing strategies for further studies of patterns of daily occupations. Four different methods were used, one on each

The results of three separate studies on ankle fractures are presented. Clinical information is provided concerning the epidemiology and a comparison of closed versus open treatment, and a discussion is presented concerning what results can be expected 30 years after closed treatment for an ankle fracture.

Liquid solubility measurements were performed by immersion of poly(octyl)methylsiloxane (POMS) in dilute aqueous solutions of homologous series of aliphatic esters and alcohols with compound specific concentrations of 20, 40, 80 and 120 ppm. Measurements were performed at 20 °C with both single- and multi-compound mixtures and linear sorption isotherms were obtained. By fitting experimentally dete

We report a theoretical study of the electronic structure and optical properties of free-standing semiconductor nanowires, based on an atomistic tight-binding approach. It is shown that the optical transition between the valence-band maximum and conduction-band minimum of an intrinsic nanowire is fully polarized along the wire axis, and this giant polarization anisotropy can be explained in terms

Recent phylogeographic work on Taricha torosa has revealed that the subspecific lineages, T. t. torosa and T. t. sierrae, are distinct evolutionary lineages that form a secondary contact zone in the southern Sierra Nevada of California. I examined the dynamics of this contact zone using two allozyme markers, mitochondrial DNA, morphometrics (head shape), and head color pattern. The subspecific lin

The effects of scattered actinic radiation on photomultipliers (Hamamatsu R-562) were investigated. Using cotton-wool to model dense biological preparations, it was found that the scattered actinic radiation received by the photomultiplier gives rise to phytochrome-like signals. This demonstrated the necessity to shield the photomultiplier from scattered actinic light for sensitive measurements wi

Popular Abstract in Swedish Den tid vi i dagens samhälle betraktar som ungdomstid blir allt längre. De ungdomar som lämnar grundskolan tillhör en åldersgrupp som är större än på länge och det stora flertalet av dem är på väg in i svensk treårig gymnasieutbildning. En övergripande specialpedagogisk idé handlar om att alla människor bereds möjlighet att ta del i ett samhälle. Samtidigt finns inte nåThis longitudinal study draws the attention to some adolescents' images of the living-, study- and learning situations into, through and out of the upper secondary school period. The aim implies an examination of the ways a study group with "severe physical disabilities" describes their experiences of phenomena in connection with processes of co-operation and influence.

Historically, agriculturally induced CO2 release from soils has contributed to rising levels in the atmosphere. However, by using appropriate management, soils can be turned into carbon sinks. Many of the dryland regions of the world are characterised by degraded soils, a high incidence of poverty and a low capacity to invest in agriculture. Two well-proven soil organic matter models (CENTURY 4.0

Popular Abstract in Swedish Denna studie visar betydelsen av ökad idrottsundervisning, fysisk aktivitet och extra motorisk träning i skolan. Undersökningen är en delstudie i Bunkefloprojektet - en hälsofrämjande livsstil. Interventionen består i att två årskullar elever har en obligatorisk rörelselektion varje skoldag. Motorikobservationer med MUGI observationsschema som underlag genomförs varje åThe aim of this thesis is to study effects of an extension of physical education/activity and motor training on motor skills, attention and cognition during a period of three years. Another aim is to develop a test, MUGI observationsschema, which could be useful in charting motor skills of school pupils. The study has two intervention groups (n=152) that have physical activity and motor training o

The introduction of PACS in a radiology department means that most functions that are available in the film-based system must be included. One important function is the radiology conference. The handling and application programs of digital workstations are normally not developed for demonstrations of many images in a limited time. This paper describes a workstation with specially designed software

Injectable bone substitutes (IBS) based on calcium phosphate (CaP) and/or calcium sulphate (CaS) are used as fillers in bone defects to stimulate bone integration and allow mechanical loading. Two types of IBS, IBS-1 is CaP+20%CaS and IBS-2 is CaS+40% hydroxyapatite, were investigated. The materials were injected into holes in the femur and tibia in rabbits. After 10 weeks the femora were subjecte
