The optical response of isolated holes in 20 nm thin gold is probed as a function of alkanethiol CH3(CH2)(x)SH (x is an element of 1-15) and protein adsorption using dark-field spectroscopy. We establish that the plasmon excitations of single and short-range ordered 60 nm holes exhibit similar E-field decay lengths delta approximate to 10-20 nm and that a single hole can be used to resolve the suc

Thirteen piston and gravity cores from the Faroe-Shetland area were investigated for their planktic and benthic foraminiferal and oxygen isotopic distributions. Eight time-slices between 18 ka BP and the present were reconstructed to study variations in surface and deep water exchange between the SE Norwegian Sea and the northeast Atlantic Ocean. Today, a relatively strong northward flow of warm N

Dermatan sulfate (DS) chains are variants of chondroitin sulfate (CS) that are expressed in mammalian extracellular matrices and are particularly prevalent in skin. DS has been implicated in varied biological processes including wound repair, infection, cardiovascular disease, tumorigenesis, and fibrosis. The biological activities of DS have been attributed to its high content of IdoA(alpha 1-3)Ga

Saccharomyces cerevisiae mutants, in which open reading frames (ORFs) displaying similarity to the aldo-keto reductase GRE3 gene have been deleted, were investigated regarding their ability to utilize xylose and arabinose. Reduced xylitol formation from D-xylose in gre3 mutants of S. cerevisiae suggests that Gre3p is the major D-xylose-reducing enzyme in S. cerevisiae. Cell extracts from the gre3

Abstract in Undetermined NMR line shape analysis and relaxation dispersion measurements for N,N-dimethyltrichloroacetamide (DMTCA) weakly aligned using poly-γ-benzyl-l-glutamate, which forms a lyotropic nematic phase when dissolved in chloroform, were used to characterize chemical exchange kinetics for the rotation around the C−N amide bond. At low temperatures (312 K), a single population-average

We examine the near-field optical properties of multilayered metal core-shell sphere nanostructures by extending the Mie theory, and demonstrate that the local-field enhancement can be increased by adding new metal shells. A local intensity enhancement of more than 10(5) times can be obtained in the cavity between the Ag core and the innermost Ag shell for proper configurations of multilayered Ag

I dagens samhälle krävs i många fall genomförande av risk- och/eller konsekvensanalyser. Krav ställs dels från myndigheter och dels inom enskilda företag och organisationer. Här kommer endast konsekvensanalyser att behandlas. Anledningen till att genomföra en konsekvensanalys kan skifta. Som nämnts kan krav på en konsekvensalanys komma utifrån från myndigheter och dels kan en analys utföras för at

Ischemia is accompanied by mitochondrial dysfunction, as assessed by measurements of mitochondrial respiratory activities in vitro. Following brief periods of ischemia, mitochondrial function is usually normalized during reperfusion. However, particularly after ischemia of longer duration, reperfusion may be accompanied by secondary mitochondrial failure. After short periods of ischemia this is ob

Uppsatsen behandlar Friedrich Nietzsches ställning i Sverige under och efter andra världskriget.

Glycine receptors (GlyRs) and specific subtypes of GABA(A) receptors are clustered at synapses by the multidomain protein gephyrin, which in turn is translocated to the cell membrane by the GDP-GTP exchange factor collybistin. We report the characterization of several new variants of collybistin, which are created by alternative splicing of exons encoding an N-terminal src homology 3 (SH3) domain

BACKGROUND AND OBJECTIVES: The published sequence of the weak. A subgroup Ael gene from Swedish individuals showed a G insertion in exon VII, causing a frameshift at codon 268 (the A1 gene has 353 codons). We wished to sequence exons VI and VII of two Norwegian Ael individuals and compare the expression of A substance on RBC from different Ael individuals. MATERIALS AND METHODS: Exon VI and VII we

Personers reaktioner har studerats genom experimentella studier samt i genomgång av litteraturen. I denna undersökning har valet av utrymningsväg vid en simulerad brand studerats utifrån olika förutsättningar vad avser avstånd till utrymningsvägen och om dörren var öppen eller stängd. En andra del i försöket studerade hur personer reagerade och uppfattade situationen om en liten brand befann sig mHow people react on fire alarm have been studied in retrospect as well as in experiments. In the present study, the choice of exit was examined with respect to the distance to exits and open or closed emergency exit. The second part covers the question on how the subjects think and react in a situation having a small fire in the escape route. The third part deals with some communication aspects re
