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. References with particular

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

Using high resolution core level spectroscopy, a surface core level shift towards lower binding energy of -0.13 eV is determined for the 2p level of the outwardly relaxed Al surface atoms on NiAl(110). Density functional theory based calculations with inclusion of final state effects yield a value of -0.14 eV for this shift in excellent agreement with experiment. We show that the initial state app

PURPOSE: In an experimental study in rats a correlation between nutritional status and hepatic attenuation in CT and signal intensities in MR imaging was shown. Is physiological nutritional status of importance in clinical CT and MR imaging? MATERIAL AND METHODS: In a cross-over study including 12 healthy volunteers (6 women and 6 men, mean age 34 years), CT and MR imaging of the liver were perfor

The optical response of isolated holes in 20 nm thin gold is probed as a function of alkanethiol CH3(CH2)(x)SH (x is an element of 1-15) and protein adsorption using dark-field spectroscopy. We establish that the plasmon excitations of single and short-range ordered 60 nm holes exhibit similar E-field decay lengths delta approximate to 10-20 nm and that a single hole can be used to resolve the suc
