Popular Abstract in Swedish Undersökning av bihåleventilation med 133-xenon washout teknik och gammakamera med tomografi, gör det möjligt att mäta ventilationen även i de djupa bihålorna som bakre ethmoidalsinus och sphenoidalsinus. Mätningar visar reproducerbara resultat hos friska försökspersoner där normala variationer i näsandningsmotstånd och kroppsläge ej påverkar mätresultaten. BihåleventilA noninvasive 133-xenon washout technique was used to evaluate the ventilation of the paranasal sinuses in healthy subjects and in patients with sinus disease. A mixture of air and 133-xenon is insufflated into the nasal cavities and passage into the sinuses is facilitated by a pressure increase created by letting the subjects inflate a balloon. A scintillation camera allowing single photon emissi

Att skriva är en sammansatt förmåga. Det är svårt att i ord formulera vad en skicklig skribents kompetens består i, och därför också svårt att undervisa i skrivande. Ett problem vid bedömning av texter är ofta att både studenter och lärare har svårt att formulera vad som gör en bra text. Här kan metatexter vara ett stöd, för både studenter och lärare. Erfarna lärare har i regel inga problem att b

This paper presents a person-centred model and a tangible computing approach to better adapt television media to meet two important needs of older people: social inclusion in their immediate surroundings and better support for one’s own reflections. Method The research project was carried out as a part of the construction, planning and implementation of a new nursing home. The implemented infrastr

Popular Abstract in Swedish Östersjön är idag ett av världens största innanhav med endast marginellt utbyte av vatten med Kattegatt via Öresund samt Lilla och Stora Bält. Saltrika inflöden från Kattegatt orsakar två salthaltsgradienter, en horisontell med mer saltrikt vatten i sydväst och mer färskt i Bottenhavet, samt en vertikal saltgradient (haloklin) med mer saltrikt bottenvatten och mer färskThe Baltic Sea is one of the world’s largest brackish water environments and is today suffering from, for example, eutrophication, spreading hypoxia, accumulations of contaminants and invasive organisms. These problems exist due to a combination of natural features that makes the Baltic Sea a sensitive ecosystem (such as long water residence time, limited water exchange, large catchment area), and

Difficulties had been identified with regard to bachelor and master theses. The quality varied too much, as did supervision. The report discusses possible ways of improving the situations,looking at other departments at Lund University, as well as the Copenhagen Business School. The report suggests some measures for improving the process as well as for supporting supervisors.

The metal beaker that was found in the house is a unique object. The shape arouses associations with late antique glasses. The beaker is covered with embossed gold bands with figure representations carried out in early Style I. The bands were probably produced around 500 AD. The body of the beaker might be contemporaneous or possibly also older, with the bands as a later addition. The beaker is co

The study of residences at central places from the Late Iron Age in Scandinavia has mainly been aimed at identifying buildings of exceptional size or function. However, until recently the archaeological situation has not been detailed enough to study the sequence of a residence for several centuries and with internal changes related to internal or external factors. New excavation results from Uppå

Popular Abstract in Swedish Enzymet histidin dekarboxylas - en nyckelroll i bildningen av histamin Histamin är en välkänd substans som är en av orsakerna till bland annat allergiska symptom. Alla som har hösnuva känner väl till hur histamin verkar, svullnande ögon och rinnande näsa. Histamin är inblandad i en mängd olika funktioner i kroppen såsom allergiska reaktioner och inflammationer av alla Histamine is involved in a variety of physiological processes like gastric acid secretion, inflammation and neurotransmission. The production of histamine is catalysed by the enzyme histidine decarboxylase (HDC), which is a strongly regulated enzyme. Mammalian HDC mRNA encodes a protein with a molecular mass of 74 kDa, which is greater than that reported for the subunit of purified mammalian HDC,

Objective: To investigate if the improved glucose tolerance previously observed at breakfast following an evening meal with boiled barley kernels derives from colonic events related to the fermentation of the elevated amounts of indigestible carbohydrates present and/or from the low-GI features. Subjects/Methods: Twenty healthy volunteers aged 19–30 years. Design: High-GI white wheat bread (WWB)

Abstract in Norwegian Thailand har etterhvert utviklet seg til å bli mange skandinaveres turistparadis. Etter tsunamikatastrofen som rammet Sørøst-Asia andre juledag 2004 fikk vi høre at den beste måten å hjelpe den thailandske befolkningen på etter hendelsen var å vende tilbake dit som turister. Den voksende turismen i Thailand har ført med seg en økt økonomisk velstand på mange av øyene solhungr

Purpose: To investigate the relative importance of spatial resolution and noise on the image quality of clinical radiographs. Methods: The spatial resolution and noise of fifteen digitised lumbar spine radiographs were altered with image processing. Three different MTF curves and three different Wiener spectra were combined into seven different combinations of spatial resolution and noise. These s

Campylobacter jejuni is one of the most common causes to bacterial gastroenteritis in the industrialised world. Also other species of the Campylobacter genus give rise to human infections. C. jejuni occurs in many different animal hosts and can be isolated from water sources. This thesis deals with the occurrence and population structure of this bacterium and related organisms in wild birds. Using
