It has been almost fifteen years ago that the top quark, the heaviest and most intriguing among the six known quarks, was observed at the Tevatron experiments at Fermilab. Some of its properties, such as the mass and the production cross sections are by now quite well known. Other important aspects, however, such as the top quark invariant mass distribution, the structure of the tWb coupling, the

The investigations of light kaonic atoms offer the unique opportunity to perform experiments equivalent to scattering at vanishing relative energies, being their atomic binding energies in the keV range. This allows the determination of the hadron-nucleus interaction at threshold without the need of an extrapolation to zero relative energy. The energy shift and broadening of the lowest-lying state

Based on a molecularly imprinted polymer, a competitive binding assay analogous to competitive enzyme immunoassay has been developed. The assay is specific for the herbicide 2,4-dichlorophenoxyacetic acid and uses, for the first time, an enzyme-labelled conjugate as a tracer. The label tobacco peroxidase allowed for colorimetric and chemiluminescence detection. The molecularly imprinted polymer wa

In this study, both diastereo- and enantioselective adsorbents for a dipeptide derivative were prepared using a molecular imprinting technique. The diastereo- and enantioisomers for the dipeptide derivative N-(benzyloxy-carbonyl)aspartylphenylalanine methyl ester (ZAPM), in addition to the α- and β-isomers, were chosen as test compounds for the investigation of the imprinting effect The close simi

Background: Recent years of research have increased the knowledge about how to support the transition to adulthood for youths with disabilities. In today’s multi-cultural societies knowledge about transitioning immigrant youths and their caregivers is still needed.Objective: To describe the expectations and needs of immigrant youths with disabilities residing in Sweden during their transition into

En plattityd; samhället är delat. Lite mera nyanserat; det verkar finnas en tendens till att strukturera den mänskliga samvarons former. Individer, liksom aktiviteter, separeras i olika kategorier vilka rangordnas mer eller mindre relevant för samhällets fungerande. Dessa processer sker utan att någon av de inblandade har något intresse i en sådan strukturering. Det kan till och med vara s

The Swedish well fare state is a young phenomenon. In the 19th and early 20th centuries there were numerous non proprietor, poor and pauper people in the Swedish countryside such as crofters, boarders and inhabitants of rural slums. Being poor also meant being more exposed to risks than more resourceful persons, and having fragile safety nets. This paper is about these poor and pauper persons of tIn the 19th and early 20th centuries there were numerous non-proprietors and paupers in the Swedish countryside, such as crofters, boarders and inhabitants of rural slums. Multisource methods such as triangulation of written documents, historical maps and archaeological evidence are used to study the living conditions, vulnerability and marginalization of boarders and inhabitants of rural slums fr

A high standard of planetary protection is important for astrobiology, though the risk for contamination can never be zero. It is therefore important to find a balance. If extraterrestrial life has a moral standing in its own right, it will also affect what we have to do to protect it. The questions of how far we need to go to protect extraterrestrial life will be even more acute and complicated w

The Autism Diagnostic Observation Schedule (ADOS) is a first-choice diagnostic tool in autism spectrum disorder (ASD). Excellent interpersonal objectivity (interrater reliability) has been demonstrated for the ADOS under optimal conditions, i.e., within groups of highly trained "research reliable" examiners in research setting. We investigated the spontaneous interrater reliability among clinicall

The diagnostic validity of the new research algorithms of the Autism Diagnostic Interview-Revised and the revised algorithms of the Autism Diagnostic Observation Schedule was examined in a clinical sample of children aged 18-47 months. Validity was determined for each instrument separately and their combination against a clinical consensus diagnosis. A total of N = 268 children (n = 171 with autis

I språkutbildning vid svenska lärosäten finns det vanligtvis ett antal studenter i varje grupp som har det studerade språket som modersmål (L1), även om majoriteten utgörs av studerande som läser språket som främmande språk (L2). I vår studie undersöker vi erfarenheter av att undervisa denna typ av grupp genom semistrukturerade intervjuer med sex universitetslärare i franska, spanska och tyska. Un

Intravesical inoculation of gram negative bacteria or isolated bacterial products into mice induces an IL-6 response which can be measured within miutes of the infection.1,2 In such infections, IL-6 is initially detected in the urine and subsequently in the serum. Similar IL-6 responses were found in human patients deliberately colonized in the urinary tract with E. coli Hu7343. IL-6 was secreted

Neutrophil influx to mucosal surfaces represents one of the earliest inflammatory responses to mucosal infection. We have been studying external interactions with urinary tract epithelial cells in an attempt to understand the molecular mechanisms behind this process. Uropathogenic Escherichia coli induced urinary tract epithelial cells to secrete the neutrophil chemoattractant interleukin-8 (IL-8)
