Collagen induced arthritis (CIA) is the most studied animal model for rheumatoid arthritis and is associated with the MHC class II molecule A(q). T-cell recognition of a peptide from type II collagen, C11256-270, bound to A(q) is a requirement for development of CIA. Lysine 264 is the major T-cell recognition site of C11256-270 and CIA is in particular associated with recognition of lysine 264 aft

This study suggests a predominantly socially-strategic function of the silver found in Viking Age hoards, more specifically, connected to the realm of customary law and the blood feud as a social institution. This suggestion is based on a quantitative and contextual analysis of the Íslendingasögur, and a comparison between the function of silver in the sagas and the composition and context of the

Wave cycles, i.e. pairs of local maxima and minima, play an important role in many engineering fields. Many cycle definitions are used for specific purposes, such as crest-trough cycles in wave studies in ocean engineering and rainflow cycles for fatigue life prediction in mechanical engineering. The simplest cycle, that of a pair of local maximum and the following local minimum is also of interes

UV-B treatment of thylakoid membranes or fractions derived from them accelerates the first rise (Fo---Fi phase) of variable fluorescence and slows down the second (Fi---Fm) rise. This can be observed for all membrane fractions but to different extents. The grana fraction is affected more by the UV-B treatment than are the intact thylakoids and the stroma lamella fraction. An exogenous electron acc

To get a proper perspective on the current status of atmospheric ozone, which protects the biosphere from ultraviolet-B (UV-B; 280-315 nm) radiation, it would be of value to know how ozone and UV-13 radiation have varied in the past. The record of worldwide ozone monitoring goes back only a few decades, and the record of reliable UV-13 measurements is even shorter. Here we review indirect methods

A control system for pneumatic variable valve actuation has been designed, implemented and tested in a single cylinder test engine with valve actuators provided by Cargine Engineering AB. The design goal for the valve control system was to achieve valve lifts between 2 and 12 mm over an engine speed interval of 300 to 2500 rpm. The control system was developed using LabView and implemented on the

The determination of accurate and precise ages for the timing of collision between oceanic plateaus and continental crust requires an understanding of how the indenting and buttressing plates respond to the collision. We present geochronological, thermochronological, geochemical and isotopic analyses of magmatic rocks from the Ecuadorian Andes, which relate to the collision of the Late Cretaceous

A technology was developed to embed nm-sized metallic features in close vicinity to semiconductor heterostructures, which allows a direct integration of resonant tunneling diodes (RTD) inside the channel of permeable base transistor. A AlGaAs/InGaAs based RTD was grown by molecular beam epitaxy (MBE), with peak current density either 70 or 120 kA/cm². A fundamental oscillation frequency

The index of an invariant subspace M of a Banach space of analytic functions in the open unit disc is defined by ind M = dim M/zM. In this paper, we provide a strong link between high index and nontangential boundary behaviour of the functions in an invariant subspace.

The Soviet era had come to an end and by 2002 a new idea of Europe was emerging which would see the enlargement of the European Union. The period called ‘transition’ was relegated to history. It denoted the transition of the Baltic and Central European states from the Warsaw Pact and the Soviet bloc to NATO and the European Union. Originally, transition was a concept used only to denote that the f

A search for events containing an isolated electron or muon and missing trans verse momentum produced in e(+/-)p collisions is performed with the H1 and ZEUS detectors at HERA. The data were taken in the period 1994-2007 and correspond to an integrated luminosity of 0.98 fb(-1). The observed event yields are in good overall agreement with the Standard Model prediction, which is dominated by single
