Under sex år har väsentliga egenskaper hos den nya så kallade högpresterande betongen studerats av svenska forskare i samverkan med ett antal företag i byggbranschen. Möjligheter och potentiella risker med det nya materialet har klarlagts. Den högpresterande betongen ger stora möjligheter till konstruktioner med högre prestanda och möjliggör mera rationella produktionsmetoder. Det ankommer nu i fö

Popular Abstract in Swedish Den här avhandlingen har behandlingsresultaten av permanent djupelektrod stimulering i hjärnan (Deep Brain Stimulation, DBS) undersökts ur såväl symptomminsknings som patients och närståendes perspektiv. DBS behandling innebär att en elektrod med fyra poler opereras in i hjärnan genom ett litet hål i skallbenet, och den kopplas till pulsgivardosa. Hela systemet är doltThe treatment related effects and personalized goal fulfilment of Deep Brain Stimulation (DBS) have been assessed in studies with different designs. The brain targets included the thalamus for medically intractable tremor in Parkinson's disease (PD) or essential tremor (ET) and the subthalamicus for reducing hypo-, bradykinesia, tremor, rigidity and dystonia in PD. A Swedish multi-center study sh

Objective: To investigate recent evidence suggesting that social factors are causally related to the development of schizophrenia. Method: I conducted a sytematic review of MEDLINE to identify possibly relevant studies. The search was limited to peer-reviewed studies and review articles appearing in English-language journals since 1996. Studies were included if they used standardized diagnostic cr

Chronic myelogenous leukemia is characterized by a specific chromosomal translocation, t(9;22), in which the ABL protooncogene and the BCR gene become juxtaposed. The chimeric BCR/ABL gene produces a P210 fusion protein with deregulated tyrosine kinase activity. We have recently isolated a complementary DNA, CRKL, which could code for an adaptor protein consisting of one SH2 and two SH3 domains an

Using surface infrared absorption spectroscopy, we have measured and assigned the vibrational spectra of six different methoxy isotopotners adsorbed on a Cu(100) surface in great detail. The assignments are based on ab initio calculations of the vibrational mode frequencies of all six isotopomers for a methoxy-Cu-5 complex. By combining different IR detectors and optical filters, we observe many,

A study of the effect of light deflection during diffusion studies of ethanol into agarose gel using holographic laser interferometry is presented. Furthermore it also demonstrates how a diffusive flux could give rise to a convective flux in holographic laser interferometry experiments. The convective and diffusive mass transfer is also theoretically compared in both a liquid phase and a gel phase

Aims Extracellular ATP acting on the P2Y(11) receptor regulates inflammatory cells. We hypothesized that polymorphisms in the receptor could influence the risk of acute myocardial infarction (AMI). Methods and results In the Malmo diet and cancer AMI case-control study (n = 3732) the P2Y(11) gene Thr-87 polymorphism was present in 19.8% of the controls and 22.9% in AMI patients (OR 1.21; P = 0.03)

The quark model does not exclude states composed of more than three quarks, like pentaquark systems. Controversial evidence for such states has been published in the last years, in particular: for a strange pentaquark Theta(1540)(+); for a double-strange state, the Xi(1862)(--), subsequently called Phi(1860)--; and for a charmed state, the Theta(c)(3100)(0). If confirmed, a full pentaquark family

We present an analytical algorithm for deriving the shapes of the deformable mirrors to be used for multiconjugate adaptive correction on a large telescope. The algorithm is optimal in the limit where the overlap of the wave-front contributions from relevant atmospheric layers probed by the guide stars is close to the size of the pupil. The fundamental principle for correction is based on a minimi

This report presents positive infrared spectroscopic identification of H2O3, a higher oxide of hydrogen of importance for the understanding of the chain formation ability of atomic oxygen and a possible intermediate in hydrogen oxygen radical chemistry. All fundamental vibrations of H2O3, isolated in an argon matrix, have been observed. In addition, several bands of HDO3, D2O3, and H2(16)O2(18)O h

In the present study, a phage display library covering the genome of Staphylococcus lugdunensis, was affinity-selected against von Willebrand factor (vWf). This led to the identification of a gene, vwbl, encoding a Putative cell surface protein of 2060 amino acids, denoted vWbl. The deduced protein has an overall organisation typical of staphylococcal cell Surface proteins, with an N-terminal sign

The purpose of the present study was to assess the role of diffusion and convection during filtration of Ficoll across the glomerular filter by comparing glomerular sieving coefficients ( h) to neutral fluorescein isothiocyanate ( FITC)-Ficoll 70/400 obtained at low ( hydropenic) vs raised ( normal) glomerular filtration rates (GFRs). The h for FITC-Ficoll was determined in anesthetized Wistar rat

A new type of supermacroporous, monolithic, cryogel affinity adsorbent was developed, allowing the specific capture of urokinase from conditioned media of human fibrosarcoma cell line HT1080. The affinity adsorbent was designed with the objective of using it as a capture column in an integrated perfusion/protein separation bioreactor setup. A comparative study between the utility of this novel cry

Mineral water and soft drinks with a perceptible off-odour were analysed to identify contaminants originating from previous misuse of the refillable polyethylene terephthalate ( PET) bottle. Consumers detected the off-odour after opening the bottle and duly returned it with the remaining content to the producers. The contaminants in question had thus been undetected by the in-line detection device

Injuries to the upper gastrointestinal tract occurring over a 30-year period in a geographically well defined region were analyzed. The incidence was low in comparison with other abdominal injuries, but duodenal and pancreatic injuries were increasingly common in the study's last decade. The stomach injuries were mainly caused by penetrating trauma. The duodenal and pancreatic injuries most common
