Human skeletal muscles are composed of two distinguishable types of fibres, which in healthy muscles appear to be randomly arranged. Large groups of one fibre type are commonly regarded as evidence of a neuropathological process affecting the peripheral nerves or the nerve cells in the spinal cord. An objective method that detects non-random arrangements as a sign of a neurogenic disorder, particu

Cytokines play a major role in lymphoid development. Defects of the common gamma chain (gamma (c)) or of the JAK3 protein in humans have been shown to result in a severe combined immune deficiency (SCID), with a profound defect in T and natural killer (NK)-cell development, whereas B-cell generation is apparently unaffected (T-B+NK- SCID). While extensive molecular and biochemical analysis of thes

Objective: The hemodynamic effects of vacuum-assisted closure therapy in cardiac surgery are debated. The aim of the present study was to quantify cardiac output and left ventricular chamber volumes after vacuum-assisted closure using magnetic resonance imaging, which is known to be the most accurate method for quantifying these measures. Methods: Six pigs had median sternotomy followed by vacuum-

The first experimental study of focusing synchrotron radiation by a parabolic planar glassy-carbon lens is presented. The lens consists of four biconcave single lenses with a curvature radius of 0.2 mm and a relief height comparable with the lens aperture (similar to1 mm). One lens gives rise to the formation of a linear focus with a length comparable with the height of a parabolic profile. The us

New software technologies are important for the future of control (and vice versa) in an age of increasing complexity. This paper discusses what are the trends.

A series of intramolecular condensation products were obtained by base-catalyzed treatment of the natural bioactive dimeric phthalide diligustilide (1) using different reaction conditions and the yields remarkably depend on these. The reaction conditions to obtain selectively the intramolecular condensation derivatives or the hydrolysis products of diligustilide (1) are described.

Heat conduction calorimetry is a convenient method to detect cement-admixture incompatibility. However, such instruments tend to be used mainly in chemical laboratories. This paper presents the design of a simple unthermostated heat conduction calorimeter that can simultaneously monitor the heat production rate in 14 samples of cement paste or mortar. As it is not thermostated, its performance is

Biomolecular recognition is often characterised by low affinity where many weak interactions work either alone or in concert, resulting in an inherent dynamic situation. For example the well-studied weak binding of cell-cell interactions is predominantly based on a range of carbohydrates that interact with numerous (protein) ligands. Finding appropriate binders to these carbohydrate structures may

The helicity structure of the diffractive electroproduction of rho mesons, e + p --> e + rho + Y, is studied in a previously unexplored region of large four-momentum transfer squared at the proton vertex, t: 0 < t' < 3 GeV2, where t' = - min. The data used are collected with the HI detector at HERA in the kinematic domain 2.5 < Q(2) < 60 GeV2, 40 < W < 120 GeV No t dependence of the r(00)(04) spin

Sweden does not have a legal definition of small and medium-sized enterprises (SMEs). There are, however, special tax rules which apply to unquoted companies and close companies. A "close company" is defined in the statutes as a company or an economic association in which a small number of people, directly or indirectly, own shares representing more than 50% of the voting rights. Close companies a

We propose a new third-order multidimensional upwind algorithm for the solution of the flow equations on tetrahedral cells unstructured grids. This algorithm has a compact stencil (cell-based computations) and uses a finite element idea when computing the residual over the cell to achieve its third-order (spatial) accuracy. The construction of the new scheme is presented. The asymptotic accuracy f

Denna rapport presenterar två nya metoder att beräkna fukttransportkoefficienten och Kirchhoffs flödespotential vid höga fuktnivåer.

Popular Abstract in Swedish Tre-dimensionell ultraljudsundersökning av livmodertappen (cervix) Syftet med avhandlingen var att utvärdera förändringar i livmodertappen (cervix) med tre-dimensionellt ultraljud och utreda om tre-dimensionellt power Doppler ultraljud kan förutsäga tiden till spontan eller inducerad förlossning hos överburna, gravida kvinnor. Avhandlingen baseras på fem studier: reprThe aim of this thesis was to evaluate cervical physiological changes by three-dimensional (3D) ultrasound during pregnancy and to investigate the ability of 3D power Doppler to predict time to spontaneous and induced delivery in prolonged pregnancy. The thesis is based on five studies: reproducibility of cervical measurements by 3D power Doppler ultrasound (study I), reference data representativ

Andrena humilis is an endangered oligolectic solitary bee and has declined in recent decades throughout western Europe. The aim of this study was to explore the pollen harvesting pattern and to determine the reproductive rate in specialized andrenid bees. We measured the amount of pollen required to produce one brood-cell, the pollen harvesting rate and compared our results with data for other spe
