A new EU directive on used vehicles has recently been introduced. It demands that for every scrapped car, at least 85% by weight must be recycled by the year 2006 and 95% by 2015. Today this level is about 80%. The growing car disassembly industry was chosen as the study object of this thesis. Due to the increased demands on recycling, the disassembly industry is expected to undergo comprehensive

Drugs of abuse testing is used in various areas of society for detection and follow-up of drug use. In routine laboratory drug testing, immunoassays are employed for initial screening of specimens to indicate the presence of drugs. To confirm a positive screening test, a secondary analysis by mass spectrometry is performed. The »cut-off« is the pre-defined concentration threshold of a drug or drug

BACKGROUND: Severe meningitis may compromise cerebral perfusion through increases in intracranial pressure (ICP) and through hypovolemia caused by a general inflammation with systemic plasma leakage. From its antiaggregative/antiadhesive and permeability-reducing properties, prostacyclin (PGI2) is a potential adjuvant treatment in meningitis, but previously published data have been ambiguous. The

Epilepsi är den vanligaste neurologiska sjukdomen efter stroke och huvudvärk, ca 60 000 personer har aktiv epilepsi i Sverige. Vi har idag tillgång till en rad mycket effektiva läkemedel, bara sedan 1989 har åtta nya epilepsimediciner registrerats. Trots den utvidgade behandlingsarsenalen bli bara två av tre patienter anfallsfria av läkemedel, för en tredjedel fortsätter anfallen att komma. Vid fa

A new influenza virus that was first detected in people in April 2009, was initially referred to colloquially as "swine flu", since it contained genes from swine, avian and human influenza viruses. It can, however, not be transmitted by eating pork or dealing with pigs. In Egypt, several hundred thousand pigs were killed in May, in spite of advice from global health authorities that such an action

Stress or psychological distress is often described as a causative or maintaining factor in psoriasis. Psychological traits may influence the appraisal, interpretation and coping ability regarding stressful situations. Detailed investigations of psychological traits in relation to stress reactivity in psoriasis are rare. The aim of this study was to examine whether patients with psoriasis who repo

The estrogen receptor coactivator Amplified in Breast Cancer 1 (AIB1) has been associated with an improved response to adjuvant tamoxifen in breast cancer, but also with endocrine treatment resistance. We hereby use metachronous contralateral breast cancer (CBC) developed despite prior adjuvant tamoxifen for the first tumor as an "in vivo"-model for tamoxifen resistance. AIB1-expression in the pre

Abstract Conclusions: Recurrences were seen in 5% of all patients with acute mastoiditis (AM). Mastoidectomy had been performed in the majority of the patients with recurrences at their first episode of AM. Compared with the group with a single episode of AM, the recurrent group exhibited more subperiosteal and ear canal abscesses, although they were not more severely ill. It appears from this stu

Microalbuminuria is an early manifestation of diabetic nephropathy. Potential contributors to this condition are reduced glomerular filtration barrier (GFB) size- and charge selectivity, and impaired tubular reabsorption of filtered proteins. However, it was recently reported that no significant alterations in charge selectivity of the GFB occur in early experimental diabetic nephropathy. We here

We consider realistic multiple input multiple output antenna systems operating over spatially colored channels with instantaneous, albeit imperfect, channel state information at the receiver and only covariance knowledge available at the transmitter. We focus on pilot-aided channel estimation in which the receiver uses minimum mean square error channel estimation. For such a setup, our goal is the

This report describes a model for the estimation of the time required to evacuate a building, by dividing the evacuation process into three phases: awareness, behaviour and response, and movement. The times required in each of these phases can be estimated separately and the sum then represents the total evacuation time. The time elapsed from the fire breaking out, to the discovery of the fire, is
