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

n this paper we introduce the Mean Effective Radiated Power (MERP) and the Mean Effective Radiated Sensitivity (MERS) as alternative figures of merit of the uplink and downlink communication performance of wireless handheld terminals. We show how they are related to the Mean Effective Gain (MEG), the total radiated power (TRP) and total receiver sensitivity (TRS).

Methods were developed for the synthesis of three different types of macrocyclic carbohydrate/amino acid hybrid molecules. In the synthesis of the first type of macrocycles, a glucosamine derivative was oxidized at C6 and the obtained sugar amino acid was coupled to tripeptides. The resulting hybrids were transformed into dimers and cyclized in a macrolactamization step to obtain C2-symmetric macr

Projektet Renässans 1.5 utgår ifrån det faktum att det i den traditionella produktutvecklingsprocessen normalt krävs flera iterationer i processens olika faser innan man kan nå en acceptabel kompromiss mellan estetiska krav och konstruktions- och tillverkningskrav. Den snabba utvecklingen inom optimeringsteknik och kunskapsbaserad konstruktion gör det möjligt att integrera ett datorbaserat formgivThe Renaissance 1.5 project was based on the observation that in traditional product development, several iterations are needed to obtain a compromise between engineering, manufacturing constraints and aesthetics. The rapid advances in optimisation methods and in knowledge-based engineering (KBE) make it possible to integrate engineering and manufacturing constraints in a computer-based industrial

Popular Abstract in Swedish Selen är ett essentiellt näringsämne som har många viktiga fysiologiska funktioner. Hos människor och djur utövar selen sin funktion bara om elementet är specifikt bundet i selenoproteiner som aminosyran selenocystein. Viktiga funktioner hos selenoproteiner är att verka som antioxidanter, upprätthålla redox-balansen i cellerna och reglera sköldkörtelhormonernas aktiviteSelenium is an essential nutrient and in animals and humans it can either be specifically incorporated into proteins as selenocysteine or randomly as selenomethionine. It can also occur as low-molecular-weight compounds and the form of selenium in foods may also influence food quality. The aims of the present studies were: to study selenium and other trace element compounds in milk and whey; to el

Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. The present thesis summarizes work based on four basic technologies: 1) use of Sulphate Reducing Bacteria (SRBs) for production of hydrogen sulphide which is used to
