The Svecofennian orogen in the Fennosandian Shield consists of several Palaeoproterozoic meta-igneous provinces that generally young progressively southwards and westwards. The understanding of the tectonic evolution of these different provinces is linked to the ability to constrain the timing of ductile deformation and metamorphism within them. In the western part of the orogen, in central Sweden

The article reports on a longitudinal study of children placed in a children's home during the first two years of the 1980s. The 26 children placed when younger than 4 years of age and staying more than 4 weeks were followed up 3 and 9 months after leaving the children's home and 5, 10, 15 and 20 years later. The children's family relations, including early attachments and later parental relations

Let A be the realification of the matrix algebra determined by Jordan algebra of hermitian matrices of order three over a complex composition algebra. We define an involutive automorphism on A with a certain action on the triple system obtained from A which give models of simple compact Kantor triple systems. In addition, we give an explicit formula for the canonical trace form and the classificat

Age-associated and degenerative loss of functional integrity in soft tissues develops from effects of cumulative and subtle changes in their extracellular matrix (ECM). The highly ordered tendon ECM provides the tissue with its tensile strength during loading. As age and exercise collude in the high incidence of tendinopathies, we hypothesized that aged tendons fail due to cumulative damage result

Postnatal constriction of the full-term ductus arteriosus produces cell death and remodeling of the ductus wall. Using a bioluminescence imaging technique, we found that after birth, the lamb ductus develops ATP, glucose, and glycogen depletion in addition to hypoxia. In vitro studies showed that cell death correlates best with ATP depletion and is most marked when both glucose and oxygen are seve

The present work demonstrates the possibilities of using macroporous silicon as a substrate for highly sensitive protein chip applications. The formation of 3D porous silicon structures was performed by electrochemical dissolution of monocrystalline silicon. The fabricated macroporous silicon network has a rigid spongelike structure showing high uniformity and mechanical stability. The microfluidi

This longitudinal paper draws on data from a larger ongoing project and examines how students conceive of their opportunities to influence their study environment and how this may be related to their self-efficacy beliefs and their study motivation. Interpretative Phenomenological Analysis (IPA) was used to analyze semi-structured in-depth interviews of 10 students of a Masters Program in Engineer

Prophylaxis is defined as the regular administration of clotting factor concentrates to prevent bleeding. Extensive data from observational studies and a recent randomized controlled trial (have established that early prophylactic treatment prevents bleeds and arthropathy in boys with severe haemophilia. The initiation of prophylaxis in young children remains challenging. To prevent arthropathy, p

Regioselectivity control was studied in palladium catalysed hydroxycarbonylation of styrene in neat water with water-soluble phosphines, mostly trisulfonated triphenylphosphine, TPPTS, but also N-bis(N', N'-diethyl-2-aminoethyl)-4-aminomethylphenyl-diphenylphosphine, N3P. The factor giving the highest changes in regioselectivity in the TPPTS system, under similar reaction conditions, is the temper

Eleven human primary rhabdomyosarcomas (RMSs), including all histological variants, were analyzed morphologically, immunohistochemically for intermediate filament proteins and actin isoforms, and by means of Northern blots with probes specific for total actin, alpha-skeletal (SK), alpha-cardiac (CARD), and alpha-smooth muscle actin messenger (m)RNAs. All tumors disclosed ultrastructural evidence o

We have undertaken the study of the Li-like spectrum of doubly ionized boron, B III. The spectroscopic data have been obtained with beam-foil spectroscopy and high-resolution spark spectroscopy. The experimental work was combined with theoretical calculations using ab initio and semi-empirical techniques. About 50 new transitions have been observed, and most of the previously known lines have been

Proteinlike copolymers were first predicted by the computer-aided biomimetic design (Physica A 1998, 249, 253-261). These copolymers consist of comonomer units of differing hydrophilicity/hydrophobicity. Heterogeneous blockiness, characteristic for such copolymers, facilitates chain folding with the formation of specific spatial packing: a dense core consisting of hydrophobic units and a polar she

How the variability of the atmospheric circulation affects precipitation in Iceland is not completely understood. Also, the sea surface temperature (SST) has a strong influence on the temperature over the country, and thereby, snow and glacial melt. This study, therefore, aims at explaining how atmospheric circulation and sea surface temperature influence seasonal and annual precipitation, and, co

Objective: to describe first-time-expectants fathers’ experiences of pregnancy. Design: an inductive method using narrative interview form and qualitative content text analysis. The text of the transcripts was coded and categorised. Settings and participants: seven first-time-expectant fathers living in a multicultural industrial town in southern Sweden were interviewed individually when their p

Contact dermatitis to rubber products are often caused by additives used during manufacture, and diagnosed from patch test with established rubber allergen series. In these series the compounds are divided into separate groups such as thiurams, dithiocarbamates and mercaptobenzothiazoles. The objectives were to investigate the substances with allergenic structures present in a diving mask giving r

The connection between the tolerances possible to obtain in a machining process and the machining forces and clamping forces in turning of ring-shaped work pieces clamped in conventional chucks with varying jaw numbers has been investigated. The results can be used for adaptive control of the clamping forces in an optimal way so that the work piece does not come loose in the course of machining an

Retrograde and transganglionic labeling techniques are commonly used to visualize subsets of neurons and sensory afferent projections in the nervous system. These methods commonly require anesthesia and surgical methods. However, some tracers can also be administered systemically in awake animals, thus reducing risks associated with anesthesia and surgery and allowing for labeling of neuronal popu
