Abundances of vanadium and bromine in 3 Centauri A - Additional odd-Z anomalies

We report abundance excesses of 1.2 and 2.6 dex, respectively, for vanadium and bromine in the hot, peculiar star 3 Cen A. Abundances for these two odd-Z elements have not been previously reported for this star. Taken with previous work, they strengthen the case of the origin of the abundance peculiarities by diffusion.

Food and secretagogue stimulation decrease the digestive enzyme content remaining in the rat pancreas

The aim of the study reported here was to investigate changes in the digestive enzyme content in the pancreas after food and secretagogue stimulation. Rats from which food had been withheld overnight were either fed (between 6 and 8 a.m.) or not before euthanasia and pancreatic excision (at 8 a.m.: 21 not fed and 21 fed) and at 4 (12 p.m.: six not fed and six fed) and 8 h later (4 p.m.: six not fe

The genus Pilosella in the Nordic countries

An unprejudiced revision of the genus Pilosella (Asteraceae) in the Nordic countries has been attempted. A completely new system for the taxonomy of these mostly facultative apomicts is presented. It is argued that all existing systems are inappropriate in the light of the complicated, and largely unknown, reproductive biology of these taxa. Previous systems have either treated these taxa as oblig

Macrophages in inflammatory bowel disease

Blood monocytes which differentiate into tissue macrophages, are unique in that they can not only initiate immune responses but can also be effector cells which contribute to the resolution of these responses. There is no single activation phenotype, and macrophages can be induced to differentiate into cells that either exacerbate or inhibit acute inflammation. Similarly, these cells can promote,

Immunochemical characterization of a monoclonal anti-Leb blood grouping reagent

A haemagglutinating monoclonal anti-LebL antibody has been obtained from a mouse-mouse hybridoma after immunization with the Leb-active oligosaccharide lacto-N-difucohexaose I, coupled to edestin. Of 13 other antibodies obtained, one was able to agglutinate enzyme-treated erythrocytes of all ABO groups and three more were considered to be anti-LebH haemagglutinins. The remaining nine antibodies di

Interactions between SH2 and SH3 domains

Src homology 2 (SH2) and SH3 domains are abundant protein and peptide binding modules in signalling molecules. Certain SH2 and SH3 domains have been shown to form functional and physical interactions. The structural basis of dimer formation was studied by docking three dimensional structures of the domains and by analysing structural and functional properties of the dimers. The experimentally veri

En studie av prisförhandlingar vid företagsförvärv

Popular Abstract in Swedish Inledningen till avhandlingens första kapitel tar avstamp i en diskussion om normativa (hur man bör göra) och deskriptiva (hur man faktiskt går tillväga) förhandlingsteorier. Normativa teorier bygger på antaganden om att människor kan och vet i stort sett allting och de ger råd om hur man bör göra. De deskriptiva förhandlingsteorierna försöker förklara hur människor fakScholars within the Process school assume that cognitive and motivational aspects within the decision and integration processes may systematically effect the outcome of mergers and acquisitions. More specifically, it has been suggested that decision makers use heuristics for simplifying information processing which may introduce bias. The main aim of the present thesis is to add to the understandi

The relationship between annual varve thickness and maximum annual discharge (1909-1971)

Annually laminated (varved) sediments from the River Angermanalven, mid-central Sweden, have been used to construct an annual 2000-year long record of varve thickness. Maximum daily annual discharge and mean varve thickness for the years 1909-1971 are significantly correlated (r = 0.87). A relationship between maximum daily annual discharge for the observed period (1909-1971) and varve thickness w

Virtual Pedagogical Agents - Beyond the Constraints of the Computational Approach

Virtual pedagogical agents (VPAs), i.e. computer generated characters in pedagogical roles, populate the digital society in increasing numbers. They are found in educational programs from preschool to university. In a broader educational context, they function as virtual medical counsellors, physical exercise coaches and guides on city web pages – and they also appear in edutainment and infotainme

Island magic and the making of a transnational region

How can an artificial island and a bridge-building project shape the dreams and plans for a transnational region? In this article I examine the making of the Oresund region of Denmark and Sweden by analyzing the intertwining of bridge construction and region building, from the early dreams and plans, to the actual construction phase, to the ceremonial opening in 2000, and to the difficult transiti

Middle Eastern mothers in Sweden, their experiences of the maternal health service and their partners involvement

ABSTRACT: BACKGROUND: Traditional patterns relating to how to handle pregnancy and birth are often challenged due to migration. The purpose of this study was to describe Middle Eastern mothers' experiences of the maternal health care services in Sweden and the involvement of their male partner. METHODS: Thirteen immigrant mothers from the Middle East who had used the maternal health services in Sw

Highly integrated direct conversion receiver for GSM/GPRS/EDGE with on-chip 84-dB dynamic range continuous-time ΣΔ ADC

This paper describes a highly digitized direct conversion receiver of a single-chip quadruple-band RF transceiver that meets GSM/GPRS and EDGE requirements. The chip uses an advanced 0.25-mum BiCMOS technology. The I and Q on-chip fifth-order single-bit continuous-time sigma-delta (SigmaDelta) ADC has 84-dB dynamic range over a total bandwidth of +/-135 kHz for an active area of 0.4 mm(2). Hence,

Inter-population variations in concentrations, determinants of and correlations between 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153) and 1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene (p,p'-DDE): a cross-sectional study of 3161 men and women from Inuit and European populations

BACKGROUND: The study is part of a collaborative project (Inuendo), aiming to assess the impact of dietary persistent organochlorine pollutants (POPs) on human fertility. The aims with the present study are to analyze inter-population variations in serum concentrations of 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153) and 1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene (p,p'-DDE), to assess inter-popul

The protease inhibitor cystatin C is differentially expressed among dendritic cell populations, but does not control antigen presentation

Dendritic cells (DC) undergo complex developmental changes during maturation. The MHC class H (MHC H) molecules of immature DC accumulate in intracellular compartments, but are expressed at high levels on the plasma membrane upon DC maturation. It has been proposed that the cysteine protease inhibitor cystatin C (CyC) plays a pivotal role in the control of this process by regulating the activity o
