So-called isothermal calorimeters are often built on the heat conduction principle. This may sound as a contradiction, as heat conduction is a result of non-isothermal conditions, but most measurements with microcalorimeters and other such instruments are essentially isothermal as the temperature differences within the instruments are in the order of 10 mK. This paper presents simple methods to es
BACKGROUND: The clinically significant antigens of the Duffy (Fy [FY]) blood group system are expressed on the red cell form of the FY glycoprotein, a promiscuous chemokine receptor and also a receptor for malarial parasites. After the cloning of cDNA coding for FY glycoprotein, the molecular basis of the three major alleles (Fya/Fyb/Fy) has been established. Because of the mistyping of the silent
The aim of this study was to estimate an influence of alpha-ketoglutarate (AKG) on volumetric bone density and geometrical and mechanical properties of the humerus in farm turkeys. All birds were kept under standard rearing conditions with constant access to water and appropriate feed, supplied in accordance with the stage of production cycle. Bone samples were collected 14 weeks after beginning o
A compact fiber-optic point-measuring fluorosensor fully adapted to clinical studies is described. The system can use two excitation wavelengths, 337 and 405 nm, obtained from a nitrogen laser directly, or after dye laser conversion, respectively. The image intensifier used in the spectrometer can be gated with a variable time delay, allowing also time-resolved spectra to be extracted, with a time
Background: Non-linearities in observed log-ratios of gene expressions, also known as intensity dependent log-ratios, can often be accounted for by global biases in the two channels being compared. Any step in a microarray process may introduce such offsets and in this article we study the biases introduced by the microarray scanner and the image analysis software. Results: By scanning the same sp

Hydrogen has been shown to occur as a trace element in many nominally anhydrous minerals. The presence of hydrogen in several of the major minerals in the Earth's mantle has received attention, due to the possibility that these phases provide a significant hydrogen reservoir. Recently an experimental and analytical procedure for hydrogen measurements in thin mineral samples by proton-proton scatte
R. M. Hare skriver första gången om superveniens i boken Language of Morals (LM). Han är inte den förste som understrukit att värdeomdömen handlar om så kallade supervenienta egenskaper – dvs. egenskaper som tillfaller bäraren av värdet i kraft av alla eller några av dess övriga egenskaper. Han ståtar dock i många arbeten med att ha varit den första som gav denna speciella relation ett namn. Det s
Strain stability of plasmid-containing recombinant organisms is clearly important for industrial applications. Stability is normally assessed by methods such as selective colony forming units or by simply measuring the recombinant product. These methods are typically performed off-line, are time-consuming, and do not give detailed information on the changes in the metabolism. In the current work,
Objectives. To assess waiting times for three groups of orthopaedic patients in Sweden and to identify factors explaining variations in waiting time. Also examined were factors associated with patients' perceptions that waiting times were too long. Design. Retrospective study. Setting and study participants. Patients from orthopaedic units at 10 Swedish hospitals participated in the study. A quest
The "White and Green'' project completed under the EU SAVE Programme reviewed policies and measures to promote energy efficiency, which involved analysing the experience with instruments that are already implemented, and assessing innovative instruments that are proposed. In particular, the practicability of using ''White Certificates" energy efficiency) along the same lines as "Green Certificates
Popular Abstract in Swedish Under vilka villkor kan etnicitet relaterad till en invandrargrupp igenkännas och erkännas mottagarlandet? Hur omformas och förändras transnationella konstruktioner av etnicitet när de sätts in och används i lokala praktiker? Uppstår nya etniska och kulturella former när en kapitalstark transnationell grupp konfronteras med en migrationssituation? I en empirisk studie The main ambition in this study is to explore new perspectives on the relationship between ethnicity and symbolic capital, that is how different forms of ethnicity around a migrant group can be recognised and valued in the host society. At the same time, it is a case study that offers an opportunity to verify theories on local translations of transnational cultural forms by an empirical and histor
Activation of the contact system has two classical consequences: initiation of the intrinsic pathway of coagulation, and cleavage of high molecular weight kininogen (HK) leading to the release of bradykinin, a potent proinflammatory peptide. In human plasma, activation of the contact system at the surface of significant bacterial pathogens was found to result in further HK processing and bacterial
At MAX-LAB the next synchrotron light source MAX-IV is currently studied (Proceedings of the seventh European Particle Accelerator Conference, EPAC 02, Paris, France, 2002). In this paper, we present a possible lattice with horizontal emittance of 1.2 nm rad at an energy of 3 GeV. The possibilities to realise the main magnetic system with high gradient integrated magnets are studied with 2D and 3D
