Recent developments in the ABINIT software package

ABINIT is a package whose main program allows one to find the total energy, charge density, electronic structure and many other properties of systems made of electrons and nuclei, (molecules and periodic solids) within Density Functional Theory (DFT), Many-Body Perturbation Theory (GW approximation and Bethe-Salpeter equation) and Dynamical Mean Field Theory (DMFT). ABINIT also allows to optimize

Mariyamma and the logic of realist explanation in sociology

Realism as a theory of science, in the view of the author of this paper, provides elegant solutions to several puzzles and dilemmas, not only in philosophy, but also to some of the most fundamental theorerical and methodological problems in social science. This paper introduces scien­tific realism, and presents one way of applying it to social science.

Housing in an enriched environment : A tool to study functional recovery after experimental stroke

Physical therapy and social interactions between the stroke patient and health-care professionals or relatives facilitate the process of recovery and promote improvement of lost neurological function after stroke. These observations can be mimicked in an experimental setting by multimodal stimulation provided in the concept of enriched environment. The enriched environment is a housing condition f

Gephyrin Cleavage in In Vitro Brain Ischemia Decreases GABAA Receptor Clustering and Contributes to Neuronal Death

GABA (γ-aminobutyric acid) is the major inhibitory neurotransmitter in the central nervous system, and changes in GABAergic neurotransmission modulate the activity of neuronal networks. Gephyrin is a scaffold protein responsible for the traffic and synaptic anchoring of GABAA receptors (GABAAR); therefore, changes in gephyrin expression and oligomerization may affect the activity of GABAergic syna

Bäckaskog - a Norbertine Abbey in the Circary of Denmark and Norway

In the twelfth century the Norbertine order was introduced in parts of Scandinavia. One initiator in the north was Eskil, the powerful archbishop of Lund. However, in the beginning of the thirteenth century the mendicant orders were introduced by successors to the archbishopric. This led to a general decline of other orders. In spite of that the Norbertines managed to prosper in Bäckaskog, an abbeIn the twelfth century the Norbertine order was introduced in parts of Scandinavia.

Sn-seeded GaAs nanowires grown by MOVPE

It has previously been reported that in situ formed Sn nanoparticles can successfully initiate GaAs nanowire growth with a self-assembled radial p–n junction composed of a Sn-doped n-type core and a C-doped p-type shell. In this paper, we investigate the effect of fundamental growth parameters on the morphology and crystal structure of Sn-seeded GaAs nanowires. We show that growth can be achieved

Lika ideal, skilda uttryck : cistercienserna och premonstratenserna i östra Danmark

Under 1100-talet kom cistercienserna och premonstratenserna att utgöra bland de mest spridda och inflytelserika religiösa ordnarna . Även om cistercienserna var en monastisk orden och premonstratenserna en klerikal orden var båda ett resultat av reformrörelser som strävade efter striktare ideal enligt deras respektive regler. För att möjliggöra detta hade de förlagt sina moderkloster i isolerade o

Residual stress analysis of machined lead-free and lead-containing brasses

Legislations demand low lead content in drinking water and low lead leaching from the water supply facilities. Lead-free brass (LFB) can fit in. The benefits of such alloy are acknowledged in both functional and environmental points of view. The relatively high strength of LFB means that the process condition and residual stress generation can be different as compared to the conventional brass. In

Corrosion of bed joint reinforcement in faced single-leaf brick facades - field survey

Bed joint reinforcement consisting of unprotected carbon steel was widely used to bridge windows and other openings in post-war brick buildings in the Scandinavian countries. Today, cracking caused by reinforcement corrosion constitute an increasing technical and economic problem, since removal of the corroding reinforcement can be both labour intensive and costly. Retrofitting measures are usuall
