A project effort estimation study

This paper outlines a four step effort estimation study and focuses on the first and second step. The four steps are formulated to successively introduce a more formal effort experience base. The objective of the study is to evaluate the needed formalism to improve effort estimation and to study different approaches to record and reuse experiences from effort planning in software projects. In the

Inner relative humidity and degree of saturation in high-performance concrete stored in water of salt solution for 2 years

The inner relative humidity (RH) and degree of saturation (S) of high-performance concrete cured for 2 years in water or 3% NaCl solution were measured at three different levels from the concrete surface (outer layer 0 to 16 mm, middle layer 16 to 32 mm, and inner layer 32 to 50 mm). The effects of many factors, such as water-to-cement (w/c) ratio, content of silica fume, and air content, were inv

A Glial Role in the Action of Electroconvulsive Therapy

Popular Abstract in Swedish Depression är en mycket vanlig och allvarlig sjukdom som drabbar ett stort antal människor någon gång i livet. På jakt efter effektiv antidepressiv behandling har forskare inom det medicinska fältet sökt efter biologiska processer kopplade till sjukdomen. På senare tid har ett flertal undersökningar visat att depression leder till förändringar inom vissa områden av hjärThe aim of the current thesis was to investigate glial responses to electroconvulsive seizures (ECS), an animal model of the fast-acting antidepressant treatment electroconvulsive therapy (ECT). Depression, a common and devastating disorder, has in recent years been associated with volumetric changes in prefrontal cortex, hippocampus and amygdala, brain regions known to be implicated in emotional

How can the rehabilitation planning process at the workplace be improved? A qualitative study from employers perspective

The aim of this study was to describe employers experiences of a work rehabilitation planning process at the workplace and how it can be improved according to quality and cost-effectiveness. Qualitative interviews were performed with 10 employers of employees that had participated in in vocational rehabilitation at a rehabilitation centre in the north of Sweden.The results showed that employers we

Subjective annoyance attributed to electrical equipments and smells - Epidemiology and stress physiology

Popular Abstract in Swedish Utbredningen av besvär som attribueras till elektrisk utrustning respektive kemikalielukter och andra odörer är ännu ej till fullo fastställd. Vidare saknas kunskap om eventuella bakomliggande faktorer för dessa besvärs uppkomst. Syftet med avhandlingen var att undersöka utbredningen av besvär som attribueras till elektriska faktorer, kemikalier och lukter, samt undersSelf-reported annoyance from electrical equipment has been in evidence since the mid-eighties, and the first reports of illness from everyday chemicals arose already in the 1960?s. However, the extent of the problem or the mechanisms behind the development of environmentally related annoyance has not yet been fully established. Increased vulnerability to stress has been suggested to be a possible

The activity in the CNS catecholaminergic systems covaries with thyroid hormone metabolism in humans

Do the CNS monoaminergic (MA) systems regulate thyroid hormone metabolism in humans? In 23 unmedicated, male, violent offenders without signs of thyroid disease, we found positive correlations between the catecholaminergic CSF metabolites HVA and MHPG and the peripheral T3/T4 ratio (rho=0.55, p=0.010 and 0.51, p=0.018), indicating that increased activity in the brain MA systems, especially the dop

Developmental biology of the Psammomys obesus pancreas: Cloning and expression of the Neurogenin-3 gene

The desert gerbil Psammomys obesus, an established model of type 2 diabetes (M), has previously been shown to lack pancreatic and duodenal homeobox gene 1 (Pdx-1) expression. Pdx-1 deficiency leads to pancreas agenesis in both mice and humans. We have therefore further examined the pancreas of P. obesus during embryonic development. Using Pdx-1 antisera raised against evolutionary conserved epitop

Speed management via in-car devices: effects, implications, perspectives

The objectives of this paper are to identify in-vehicle systems for speed management that have been or are being developed, and to suggest recommendations for the implementation of systems that will effectively influence driving speeds and thereby significantly increase safety. The best safety effect is expected from an "intelligent" gas pedal, more specifically the automatic speed limiter. Howeve

Cost of illness of adult diabetes mellitus underestimated if comorbidity is not considered

OBJECTIVE: To determine costs of illness for adult diabetes mellitus (DM), including complications caused by DM. DESIGN: A population-based multicentre cross- sectional study including an interview and a physical examination of patients identified as having DM. The patients' medical records were analysed regarding diagnoses and complications attributable to DM. SETTING: Eight health care centres o
