Staden och resandet : Mötet mellan planering och vardagsliv

Popular Abstract in Swedish Avhandlingen behandlar vardagslivets resor i staden. Utgångspunkten är de negativa konsekvenser som resor, framför allt med bil, har för miljön. Bilismen är ett fenomen som dominerar stora delar av samhället och istället för att minska i omfattning tycks den själv driva fram ett ökat bilberoende genom att avstånden och kraven på snabba transporter ökar. I slutändan handUrban areas are geographically dispersed. There are built-in distances between housing, jobs and services. These distances call for mobility and fast means of conveyance. Society is dominated by and dependent on motoring. Cars have a negative impact on the environment and prognoses indicate an increase in the amount of travelling. The aim of this dissertation is to explain why travel behaviour wit

Tissue reactions evoked by porous and plane surfaces made out of silicon and titanium.

Square-shaped silicon or titanium implants with plane or porous surfaces surrounded by a rim of silicone were implanted in the rat abdominal wall for evaluation of the tissue response after one, six, or 12 weeks. Cell damage was identified as increased membrane permeability using fluorescence microscopy by injection of propidium iodide prior to the killing of the rats. Capsule thickness and immuno

Psychological factors and metabolic control in insulin-dependent diabetes mellitus

This doctoral thesis consists of six studies concerning persons with insulin dependent diabetes mellitus (IDDM). The first two deal with relationships between life events, social support and metabolic control (HbA1C) over a two year period. For the female subjects, results obtained for this period were inconsistent. For the male group, negative life events and poor social support were found to be

Performance of iterative CDMA receiver with channel estimation in multipath environments

Most works published on iterative CDMA receivers assume perfect channel knowledge or very simple channel models like the flat-fading channel. We want to extend the scope to multipath propagation scenarios and suggest an iterative scheme with channel estimation in the uplink of a chip-synchronous CDMA system. Channel estimates rely on pilot symbols and a posteriori probabilities on code bits of a S

The wood-decaying fungus Hygrophoropsis aurantiaca increases P availability in acid forest humus soil, while N addition hampers this effect

We evaluated the influence of the brown rot fungus Hygrophoropsis aurantiaca on P solubility in the humus layer of a podzolic forest soil. This fungus is known to exude large amounts of oxalic acid that may stimulate weathering of minerals and increase dissolution of humus, which in turn may increase P availability in the soil surrounding the fungus. Humus was inoculated using small wooden pieces

Body size and risk of colon and rectal cancer in the European prospective investigation into cancer and nutrition (EPIC)

Background: Body weight and body mass index (BMI) are positively related to risk of colon cancer in men, whereas weak or no associations exist in women. This discrepancy may be related to differences in fat distribution between sexes or to the use of hormone replacement therapy (HRT) in women. Methods: We used multivariable adjusted Cox proportional hazards models to examine the association betwee

A microarray approach for identifying mutated genes

This study was performed to evaluate if microarray technology can identify genes using their transcriptionally defective mutant alleles. Three barley (Hordeum vulgare L.) mutant strains, xantha-h57, xantha-f27 and xantha-g28, with mutations in the genes encoding the three subunits of the chlorophyll biosynthetic enzyme magnesium chelatase, were used in a reconstruction experiment. The mutation xan

Are important patient-rated outcomes in community mental health care explained by only one factor?

Introduction: The study tested whether four commonly used patient-rated outcomes are explained by only one factor, reflecting a general appraisal tendency of patients. Method: Quality of life, needs and symptoms were rated by 92 patients in community mental health care at baseline and after 18 months and 6 years follow-up periods. At follow ups treatment satisfaction was also assessed. Scores and

Evaluation of endometrial receptivity during in-vitro fertilization using three-dimensional power Doppler ultrasound

Objective To compare sonographic endometrial characteristics in in-vitro fertilization (IVF) cycles between women who conceive and those who do not. Methods Thirty-five women undergoing IVF treatment participated in the study. Using three-dimensional (3D) power Doppler ultrasound, we assessed endometrial patterns, volume and vascularization, after follicle stimulating hormone (FSH) stimulation but

Paired multiplex reverse-transcriptase polymerase chain reaction (PMRT-PCR) analysis as a rapid and accurate diagnostic tool for the detection of MLL fusion genes in hematologic malignancies

The MLL gene in chromosome band 11q23 is frequently rearranged in acute lymphoblastic and acute myeloid leukemias. To date, more than 50 different chromosomal regions are known to participate in translocations involving 11q23, many of which affect MLL. The pathogenetically important outcome of these rearrangements is most likely the creation of a fusion gene consisting of the 5' part of the MLL ge

Short hospital stay augmented with education and home-based rehabilitation improves function and quality of life after hip replacement - Randomized study of 50 patients with 6 months of follow-up

Background Because of current cost restrictions, we studied the effect of a shorter hospital stay on function, pain and quality of life (QOL) after total hip replacement (THR). Patients and methods 50 patients from two hospitals were randomized into a study group (SG) of 27 patients receiving preoperative and postoperative education programs, as well as home visits from an outpatient team, and a c

Inter-tester reliability of a new diagnostic classification system for patients with non-specific low back pain

Most patients referred to physiotherapy with low back pain are without a precise medical diagnosis. Identification of subgroups of non-specific low back pain patients may improve clinical outcomes and research efficiency. A pathoanatomic classification system has been developed, classifying patients with non-specific low back pain into 12 different syndromes and three subcategories based on histor

Hearing thresholds in four-year-old children with weak or no transient-evoked otoacoustic emissions

Play audiometry is part of the general developmental screening covering 4-year-old children in the city of Malmo (Sweden). In an open study, 10% of the cohort was tested with transient-evoked otoacoustic emissions (TEOAEs), using the ILO88 system. The aim was to reveal a hearing loss exceeding 25 dB HL in 4-year-old children. As the first step in determining whether emissions can be used as an eff
