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

Females of the common frog, Rana temporaria, spawn synchronously at communal breeding sites, forming a communal egg mass of individual spawn clumps. A total of four spawning sites were studied. In the centre of the communal egg mass, daily maximum temperature was higher and minimum temperature lower than further out. Spawn clumps in the centre of the communal egg mass developed faster than single

Study objectives: This study was conducted to gain insight into patients' comprehension, recognition, and experience of exacerbations of COPD, and to explore the patient burden associated with these events. Design: A qualitative, multinational, cross-sectional, interview-based study. Setting: Patients' homes. Patients: Patients (n = 125) with predominantly moderate-to-very severe COPD (age >= 50 y

Popular Abstract in Swedish Avhandlingen behandlar inlärning av italienska som ett av två modersmål (svenska/italienska) hos tvåspråkiga barn och som andraspråk hos svenska vuxna som lär sig italienska i Italien. Särksilt fokus ligger på ett barn som lär sig italienska som ett av två modersmål i Sverige och vi ställer oss frågan om hans italienska kommer att utvecklas som hos italienska enspråkigaThis thesis deals with the development of the DP (the Determiner Phrase) in bilingual first (2L1) and in adult second (L2) language acquisition of Italian, with a focus on a case study of Italian as a second first language. The thesis suggests that the bilingual children and the Swedish adult learners develop the Italian DP differently. The child acquiring Italian as a second first language develo

The cross section for the diffractive deep-inelastic scattering process ep -> eX(P) is measured, with the leading final state proton detected in the H1 Forward Proton Spectrometer. The data analysed cover the range x(P) < 0.1 in fractional proton longitudinal momentum loss, 0.08 < vertical bar t vertical bar < 0.5 GeV-2 in squared four-momentum transfer at the proton vertex, 2 < Q(2) < 50 GeV2 in
