In this study, a large, farm-based, co-digestion plant in southern Sweden, using manure and various food industry wastes is investigated concerning its use of energy and its emissions of greenhouse gases from a life cycle perspective based on measured, site-specific data. The biogas is upgraded and utilized as a vehicle fuel, distributed via the natural gas grid. The case-study also includes a nov
This work is part of a research project studying the learning of fine motor skills in rats. A system for tracking a rat paw using a system of high-speed cameras is presented along with preliminary analysis of the correlation between paw movement and neural data. The tracking method is generative, modeling the rat paw as a set of linked ellipsoids. To find the most probable paw pose a number of hyp
It has been suggested that plasma-derived factor VIII products induce fewer inhibitors than recombinant factor VIII products. We investigated the relationship of factor VIII product type and switching between factor VIII products with the risk to develop inhibitors. This multicenter retrospective cohort study included 316 patients with severe hemophilia A born between 1990 and 2000. The outcome wa
The effects of cypermethrin, a commonly used pyrethroid insecticide, were studied in small in situ enclosures situated in an eutrophic lake over an 11-day period. The experimental design used a regression principle that included three untreated controls and a gradient of six unreplicated cypermethrin concentrations, ranging from 0.01 to 6 mug/l. This paper is the second in a series of two and desc
Objectives: To assess the interval change of the minimal joint space width (MJS) in radiographs of the tibiofemoral (TF) joint and of the patellofemoral (PF) joint with a 2-year follow-up in middle-aged people with longstanding knee pain with or without radiographic osteoarthritis (OA) and to study the precision of the MJS measurements. Design: In the format of a prospective study of early OA the
A wide set of biochemical and spirometrical parameters was applied to a group of 41 welders. The obtained parameters were analyzed by the pattern recognition method: principal-components analysis (PCA) and mutual contribution analysis (MCA). The aim of the investigation was to find out which of 23 parameters had an influence on the pulmonological indices of COPD. It was found that PCA gave a subst
The sorption behavior of three benzyl alcohol derivatives with different hydrophobicities into sonicated and extruded DODAC dispersions has been studied using NMR spectroscopy and NMR diffusometry. We show that there is an increased sorption into a sonicated dispersion below the phase-transition temperature (Tm) as compared to an extruded dispersion. This may be explained by the incomplete lipid c
Interpenetrating polymer systems based on crosslinked polyurethane (PU) and polystyrene (PS) were prepared at room temperature by a one-shot (in situ) method, starting from an initial homogeneous mixture of reagents via noninterfering mechanisms. Both polymerizations were performed either simultaneously or one after the other. True simultaneity at every stages of the process is not possible. Despi
OBJECTIVES This study was designed to investigate the loss of well-being, in terms of lift-years, overall and in patients randomized to metoprolol versus carvedilol in the Carvcdilol Or Metoprolol European Trial (COMET). BACKGROUND The ultimate objectives of treating patients with heart failure are to relieve suffering and prolong life. Although the effect of treatment on mortality is usually desc
The purpose of this dissertation is to evaluate the effectiveness and cost-effectiveness of Multisystemic Therapy (MST) in Sweden. This evaluation is set against the background of evidence-based social work practice and is organized around four separate but interrelated studies. The first of these studies used program theory reconstruction to investigate three conceptualizations of evidence-based
Choline acetyltransferase (ChAT) is the key-enzyme for acetylcholine (ACh) synthesis and constitutes a reliable marker for the integrity of cholinergic neurons. Cortical ChAT activity is decreased in the brain of patients suffering from Alzheimer's and Parkinson's diseases. The standard method used to measure the activity of ChAT enzyme relies on a very sensitive radiometric assay but can only be
We report a case of neuropathy induced by vibration and compression in the hand of a dental hygienist. Her hand function was improved considerably by repeated treatment during which EMLA(R) cream (EMLA(R) cream is a local anaesthetic agent containing lidocain 2.5% and priolocain 2.5%) was applied to the forearm to induce cutaneous anaesthesia.
BACKGROUND: Lead time, the estimated time by which screening advances the date of diagnosis, is used to calculate the risk of overdiagnosis. We sought to describe empirically the distribution of lead times between an elevated prostate-specific antigen (PSA) and subsequent prostate cancer diagnosis. METHODS: We linked the Swedish cancer registry to two independent cohorts: 60-year-olds sampled in 1
OBJECTIVE: The aims of this study were: to follow the course of recovery of motor function following acute stroke, as assessed by the Physiotherapy Clinical Outcome Variables Scale (COVS), and; to investigate the ability of this instrument to predict length of hospital stay, discharge destination and future home facility. METHODS: In this prospective longitudinal study, COVS was registered at admi
Prior studies have found that firms often find it difficult to implement innovative pricing strategies, such as value-based pricing, due to the organizational barriers they face in the implementation process. This case study of a manufacturing firm’s implementation of value-based pricing through the use of customer value map analysis (CVMA) examines the effect of these organizational barriers. Key
High EGR rates combined with turbocharging has been identified as a promising way to increase the maximum load and efficiency of heavy duty spark ignition Natural Gas engines. With stoichiometric conditions a three way catalyst can be used which means that regulated emissions can be kept at very low levels. Most of the heavy duty NG engines are diesel engines which are converted for SI operation.
