Today´s society depend on electric energy, in nuclear power plants this can be produced. Each nuclear reactor is situated inside a concrete containment reinforced with a post-tensioning system. The aim of this report is to analyse the state of the post-tensioning systems at Ringhals nuclear power plant. The purpose of a containment is to protect the outside world if an accident should occur. Tight

Den snabba utvecklingen inom medicinsk forskning har resulterat i nya effektiva läkemedel för de personer som drabbats reumatoid artrit (RA). Organisations- och samhällsförändringar samt en ny generation patienter har betydelse för arbetsterapeutens framtida kompetens. Syftet var att undersöka behov av kompetens för arbetsterapeuter inom reumatologisk specialistvård. Studien är deskriptiv och pro

Objective: Measurement of fetal scalp blood lactate is a supplementary tool to cardiotocography in the case of a non-reassuring tracing. Several hand-held lactate meters have been launched, all with differentials in absolute values. Therefore, the reference intervals must be calculated for each device. The internationally accepted reference interval is based on measurement with Lactate ProTM with

Background: Sonographers have a high risk of musculoskeletal disorders. Sonography involves strenuous postures in the neck and upper limbs, and is visually demanding. Echocardiography is especially challenging, with static postures and monotonous movements. Aim: The overall aim of this thesis was to identify ergonomic risk factors for pain in sonographers, and to propose actions for sustainable wo

This paper investigates a time interval within the Late Ludfordian (Late Silurian), involving changes in faunal composition (the Lau Event), a major positive carbon isotope excursion (CIE), and contemporaneous sea-level changes in remote palaeo-basins. Based on the Silurian strata of Gotland (Sweden), we integrate sequence stratigraphy, carbon isotope stratigraphy, and platform-scale palaeoecologi

An energy system that relies on fossil fuel is not sustainable. Emissions, such as carbon dioxide, nitric oxide and corpuscles, affect the climate and pollute the air. Furthermore, the supply of oil, coal and natural gas is located a few places worldwide, which can give provide incentive to geopolitical conflicts for access to these areas. This is not a local issue for Tjörn, nor even a national i

Background: Epidemiological studies that assess the health effects of long-term exposure to ambient air pollution are used to inform public policy. These studies rely on exposure models that use data collected from pollution monitoring sites to predict exposures at subject locations. Land-use regression (LUR) and universal kriging (UK) have been suggested as potential prediction methods. We evalua

An instrument with integrated flow injection analysis (FIA) system has been developed for on-line monitoring a process for conversion of biomass under field condition. The instrument consists of a newly designed biosensor for easy renewal of the bio-receptor without disassembling the sensor, a FIA controller for controlling the analysis operations, and a computer-based data acquisition system for

A novel design of a biochemical oxygen demand (BOD) biosensor has been developed for on-line monitoring of easily biodegradable organic compounds in aqueous samples. The biological recognition element of the sensor could be easily renewed by injecting new bacterial paste without disassembling the sensor system. The sensor measurements were carried out in the initial-rate mode using a flow injectio

Background: During rectal cancer surgery the bowel may contain viable, exfoliated cancer cells, a potential source for local recurrence (LR). The amount and viability of these cells can be reduced using intraoperative rectal washout, a procedure that reduces the LR risk after anterior resection. The aim of this study was to analyse the impact of washout on oncological outcome when performed in Har

Background - Osteoarthritis (OA) is the most common joint disease encountered throughout Europe. A task force for the EULAR Standing Committee for Clinical Trials met in 1998 to determine the methodological and logistical approach required for the development of evidence based guidelines for treatment of knee OA. The guidelines were restricted to cover all currently available treatments for knee O

The genus Bicyclus is one of the largest groups of African butterflies, but due to the generally cryptic nature and seasonal variation of adult wing patterns, there has been a lot of systematic confusion. With a large research community working with the model species Bicyclus anynana there has been increasing interest in the evolutionary history of the genus. A previous phylogeny started to unrave

This report presents basic concepts around resources, resource efficiency and the Circular Economy. The limitations and the opportunities within the Circular Economy are identified and clearly presented. The current policy landscape in the EU as well as in Sweden is thoroughly analysed and a set of policy areas with a significant untapped potential for resource efficiency is identified. The policy
