A novel polymeric material, off-stoichiometry thiol-ene-epoxy (OSTE+), has been evaluated for the fabrication of neural implants. OSTE+ is easily photo-structurable and exhibits mechanical properties suitable for stable implantation of the probe into brain tissue, while being sufficiently soft at physiological temperatures to reduce living tissue damage. The facile processing of OSTE+ allows use i

The interest in the evaluation of health effects due to EMF has accelerated in the last decades, mostly motivated by the occupational and environmental exposures to humans by such non-ionizing fields. The increasing exposure to electromagnetic fields has been suspected to contribute to the rising incidence of cancer in industrialized countries Despite detailed analysis which provide a wealth of ac

I alla tider och på alla platser har människan försökt förstå hur världen hänger ihop. Sökandet efter den substans som bygger världen har lett oss till upptäckterna av molekylerna, atomerna och atomernas byggstenar. Och när man tränger längre och längre in i materiens märkligheter finner man att svaren inte bara ligger i vad byggstenarna är, utan också hur de trivs med varandra. Växelverkan – hur

This essay is about drinking cups in the symposion setting on painted ceramic. The goal of this essay is to study different kinds of cups and how they were used. I found two main kinds of cups kylix and skyphoi. The kylix was more represented then the skyphoi. I also found that kottabos was one of the most represented motive. And I also focus on difference of black and red figure vases. The method

The development of a forest stand in south-eastern Norway during the last 9000 years is investigated by pollen and charcoal analyses. The aims are to identify factors that have influenced current biodiversity, which includes the lichen Usnea longissima, and examine the immigration and establishment of the current dominant tree Picea abies. Fire has been a variable but major disturbance factor at t

Using a crystalline embedding scheme it has recently become possible to study free-standing III - V nanowires with cross-sectional scanning tunnelling microscopy (XSTM). In the present paper we discuss how this novel method can be used for direct atomically resolved imaging of the interior of nanowires. We will focus in particular on two areas where this method provides unique possibilities. First

Hydrophobic interactions are highly selective, and differences in surface hydrophobicities between proteins can be used as an efficient handle to facilitate protein isolation. Aromatic amino acid residues are of particular importance for molecular recognition because they have a key role in several biological functions. The hydrophobicity of a protein can easily be altered with minor genetic modif

A detailed analysis of the mobilizable, ColE1-like resistance plasmid, pUB2380, is reported. The 8.5-kb genome encodes six (possibly seven) major functions: (1) a ColD-like origin of replication, oriV, with associated replication functions, RNAI and RNAII; (2) a set of active mobilization functions highly homologous to that of ColE1, including the origin of transfer, oriT; (3) a ColE1-like multime

Biomass gasification for energy or hydrogen production is a field in continuous evolution, due to the fact that biomass is a renewable and CO2 neutral source. The ability to produce biomass-derived vehicle fuel on a large scale will help to reduce greenhouse gas and pollution, increase the security of European energy supplies, and enhance the use of renewable energy. The Varnamo, Biomass Gassifica

von Willebrand disease (VWD) is the most common inherited bleeding disorder characterized by spontaneous or tissue injury related, mostly mucocutaneous, bleeding events. VWD affects both males and females and is caused by quantitative or qualitative deficiency of von Willebrand factor. The diagnostic procedure is complicated because VWD is highly heterogeneous, and differential diagnosis from plat

Several studies have proposed aerobic methane (CH4) emissions by plants. If confirmed, these findings would further increase the imbalance in the global CH4 budget which today underestimates CH4 sinks. Oxidation by OH-radicals in the troposphere is the major identified sink followed by smaller contribution from stratospheric loss and oxidation by methano- and methylotrophic bacteria in soils. This
