During biosynthesis of chlorophyll, Mg2+ is inserted into protoporphyrin IX by magnesium chelatase. This enzyme consists of three different subunits of approximate to 40, 70 and 140 kDa. Seven barley mutants deficient in the 40 kDa magnesium chelatase subunit were analysed and it was found that this subunit is essential for the maintenance of the 70 kDa subunit, but not the 140 kDa subunit. The 40

The photochemistry of low lying excited states of six different fluorinated bromobenzenes has been investigated by means of femtosecond laser spectroscopy and high level ab initio CASSCF/CASPT2 quantum chemical calculations. The objective of the work was to investigate how and to what extent light substituents, position on the benzene ring and number, would influence the dissociation mechanism of

Myometrial norepinephrine was measured consecutively with high-performance liquid chromatography in women who delivered by cesarean section. The previously recorded marked reduction in tissue norepinephrine at the end of normal pregnancy was confirmed. When cesarean section was performed because of abruptio placentae/hemorrhage, impending asphyxia, dystocia or preeclampsia, the norepinephrine conc

Electron emission, in resonance with soft X-ray absorption, appears to provide a measure of the dispersion of the highest occupied and the lowest, core-hole distorted, unoccupied pi-bands in poly(p-phenylenevinylene).

The water vapour resistance of clothing ensembles is not as commonly determined as dry thermal insulation. The measurement techniques are more complicated and the measurement values differ among laboratories. Due to complicated moisture transfer process through clothing ensemble, the moisture absorbed and evaporated varies in transient and steady state phases depending on properties, thickness of

Repeated ribs are frequently employed to promote turbulence and to enhance heat transfer in various ducts. In the present study, liquid crystal thermography was applied to the study of heat transfer from a square channel having one surface heated at uniform heat flux and roughened by repeated ribs. The continuous and truncated ribs, having square sections, with height-to-hydraulic diameter ratio o

Popular Abstract in Swedish I Sverige har andelen förtidspensionärer ökat under lång tid och uppgick år 1998 till 7.6% av befolkningen i arbetsför ålder (16-64 år). Den vanligaste orsaken till att en individ förtidspensioneras är reducerad arbetsförmåga till följd av problem i rörelseorganen. Kunskaperna om förtidspensionärers livskvalitet är bristfälliga. Syftet med denna studie var att studera lThe starting-point of this thesis was the high rate of disability pensioners in Sweden and the lack of knowledge about what a disability pension entails for quality of life (QL). The aim of the study was to gain knowledge about QL among disability retirees with musculoskeletal disorders (ERPs). A questionnaire was sent in 1992 to 450 ERPs in Kristianstad Municipality, Sweden, granted their disabil

In Sweden, traumatic brain injury (TBI) is a major cause of disability across all ages, and the need for rehabilitation and long-term follow-up is as important as in many other countries. This article presents the rehabilitation of TBI in Sweden. Strengths and weaknesses of TBI rehabilitation within the Swedish healthcare system are described, together with examples of research and development.

PURPOSE: To determine the fate of the infrarenal aneurysm neck and suprarenal aorta after endovascular exclusion of abdominal aortic aneurysms (AAAs). METHODS: Thirty-four patients underwent endovascular AAA repair between January 1994 and December 1995 using custom-made stent-grafts constructed from polyester graft material and modified self-expanding Gianturco Z-stents sutured to the graft orifi

A general formalism is presented for the interpretation of experiments in which a laser pulse (or pump pulse) creates charge carriers that are subsequently probed by a broadband THz pulse (or probe pulse). The time dependence of the sample properties is described in terms of the conductivity (,), where the dependence on frequency describes the intrinsic properties of the charge carriers and the de

A novel gel structure called the "plum-pudding" gel was described by us previously. I The gel was composed of randomly dispersed microgel particles ("plums") in a conventional hydrogel network. Depending on the preparation conditions, the microgels can be incorporated into the gel as expanded networks or dense collapsed globules. Where the microgel particles exist as collapsed globules, they have

This paper focuses on challenges in implementation of research in community-based occupational therapy practice. Based on a two-year project in a south Swedish municipality aiming at studying implementation of structured assessment procedures in the housing adaptation process, the first purpose is to provide a detailed project description, and the second is to report on first results identifying c

Drainage of peatlands increases the transport of suspended solids (SS) and the leaching of nutrients to downstream receiving waters. Increased settling of peat and eutrophication of lakes has been noted in many studies downstream from peat mines. Treatment alternatives have therefore been developed since the early 1980s to reduce the environmental impacts of peat mining. New, efficient methods suc

Popular Abstract in Swedish Det kan finnas en risk för att enskilda individer med läpp-käk-gomsplalt (LKG) kan möta problem ur psykosocial synpunkt som en konsekvens av den medfödda avvikelsen. LKG är en av de vanligaste medfödda avvikelserna och sett ut den synpunkten synes det viktigt att närmre undersöka detta antagande. Detta leder till den viktiga frågan om det är LKG-spalten som sådan som ärIn study I, 55 adolescents with cleft lip and palate and 31 adolescents without cleft filled out two questionnaires: the Tennessee Self-Concept Scale to assess self-concept, and the Eysenck Personality Questionnaire Inventory to assess the degree of introversion. In studies II & III, data regarding physical characteristic and general intellectual capacity were obtained from the Swedish Nationa
