Thin metallic nanowires are highly promising candidates for plasmonic waveguides in photonic and electronic devices. We have observed that light from the end of a silver nanowire, following excitation of plasmons at the other end of the wire, is emitted in a cone of angles peaking at nominally 45-60 degrees from the nanowire axis, with virtually no light emitted along the direction of the nanowire
Statistical analysis of long-term morphological data on coastal sedimentary features provides important information on the processes governing these features and their evolution in space and time. In this paper, seasonal, yearly and decadal (i.e. long-term) behavior of coastal morphological features is derived from field data by using both simple and advanced statistical techniques. The sedimentar
In the last two decades, the Swedish welfare state has been radically transformed in a neo-liberal direction, including extensive decentralisation and marketisation of the education sector with significant consequences for the work and professional identities of its teachers. Teacher education has also been directly included in this transformation. The present article addresses the changes that ha
A landscape genetics approach was applied to common goby (Pomatoschistus microps) sampled from three estuaries (six sites) of the Portuguese coast. Individuals of each site were genotyped for eight microsatellite loci and levels of genetic diversity and differentiation were correlated to present-day estuarine characteristics and historical events. A general ecological state for each sampling site
Background: Ensiling is a common method of preserving energy crops for anaerobic digestion, and many scientific studies report that ensiling increases the methane yield. In this study, the ensiling process and the methane yields before and after ensiling were studied for four crop materials. Results: The changes in wet weight and total solids (TS) during ensiling were small and the loss of energy
By means of electronic transport, we study the transverse magnetic anisotropy of an individual Fe-4 single-molecule magnet (SMM) embedded in a three-terminal junction. In particular, we determine in situ the transverse anisotropy of the molecule from the pronounced intensity modulations of the linear conductance, which are observed as a function of applied magnetic field. The proposed technique wo
Protein kinase C (PKC) δ is a regulator of apoptosis with both pro- and anti-apoptotic effects. The mechanistic basis for the discrepant effects is not completely understood. Here we show that Smac interacts with PKCδ. The interaction depends on the N-terminus of Smac and is disrupted upon treatment with paclitaxel. This is associated with release of Smac into the cytosol. Activation of PKCδ rescu
Combined data from four fusion-evaporation reaction experiments were utilized to investigate deformed and superdeformed structures in Zn-62(30)32. Combination of the Gammasphere gamma-ray spectrometer and ancillary particle detection systems allowed for the connection of rotational bands to well-known, low-lying excited states in Zn-62, as well as spectroscopy of discrete high-spin states reaching
Structural glass-timber composite beams and shear wall elements were investigated in terms of their mechanical behaviour, energy performance and their LCA performance. The load bearing components were manufactured using annealed float glass which was adhesively bonded to the timber with different adhesives. The results show, among other things, that is is possible to join the two materials glass a
BackgroundDimethyl sulfoxide (DMSO) is essential for the preservation of liquid nitrogen-frozen stem cells, but is associated with toxicity in the transplant recipient. Study Design and MethodsIn this prospective noninterventional study, we describe the use of DMSO in 64 European Blood and Marrow Transplant Group centers undertaking autologous transplantation on patients with myeloma and lymphoma
Popular Abstract in English Parkinson’s disease (PD) is the second most common, after Alzheimer’s disease, neurodegenerative disease in man. Stiffness in joints, shaky hands, and slowness of movements make it difficult for people with PD to complete normal daily tasks like buttoning up a shirt. Additionally, PD affects memory, mood, sleep and the function of the gastro-intestinal tract. Over time,Parkinson’s disease (PD) is currently the second most common neurodegenerative disorder (after Alzheimer’s disease). PD is diagnosed on its motor symptoms, which include akinesia, bradykinesia, rigidity, postural imbalance and resting tremor. It is well established that the motor symptoms develop due to lack of dopamine in the striatum. This is caused by progressive degeneration of dopaminergic ne
We synthesized twisted bilayer graphene on single crystalline Ni(111) thin films to analyze the statistical twist angle distribution on a large scale. The twisted bilayer graphene was formed by combining two growth methods, namely the catalytic surface reaction of hydrocarbons and carbon segregation from Ni. Low energy electron diffraction (LEED) investigations directly revealed dominant twist ang
The major histcompatibility complex (MHC) is a vital component of the adaptive immune system in all vertebrates. This study is the first to characterize MHC class I (MHC-I) in blue tits (Cyanistes caeruleus), and we use MHC-I exon 3 sequence data from individuals originating from three locations across Europe: Spain, the Netherlands to Sweden. Our phylogeny of the 17 blue tit MHC-I alleles contain
ESI-LC-MS/MS method with isotope dilution and SPE based on cation-exchange was developed for determination of free and total Nε-(1-Carboxymethyl)-l-Lysine (CML) and free Nε-(1-Carboxyethyl)-l-Lysine (CEL). The use of nonafluoropentanoic acid in mobile phase was omitted, SPE recoveries of 82±3% and 91±10% (n=6) for CML and CEL respectively and, calibration curves (R(2)>0.9985) were attained. The me
A paired cranked Nilsson-Strutinsky-Bogoliubov (CNSB) model is presented, which employs the same method to calculate the liquid-drop energy and moment of inertia as the unpaired cranked Nilsson-Strutinsky (CNS) model. In the CNSB model, the energy minimization is carried out in the mesh of pairing gaps Delta and Fermi levels lambda as well as deformation parameters. The high spin states in Lu-161
The Cerro de Pasco epithermal Cordilleran base metal deposit in central Peru consists of two mineralization stages which are spatially and genetically related to a mid-Miocene diatreme-dome complex. In order to constrain the duration of the magmatic-hydrothermal system at Cerro de Pasco, U-Ph age determinations and Hf isotope determinations have been conducted on single zircon grains. Biotite from
In this paper three unit root tests that allow for a break in both the seasonal mean and linear trend of the data are proposed. The tests, which can be seen as smallsample corrected versions of already known asymptotic tests, are shown to perform very well in simulations, and much better than their asymptotic counterparts.
