Optical properties of rotationally twinned InP nanowire heterostructures
We have developed a technique so that both transmission electron microscopy and microphotoluminescence can be performed on the same semiconductor nanowire over a large range of optical power, thus allowing us to directly correlate structural and optical properties of rotationally twinned zinc blende InP nanowires. We have constructed the energy band diagram of the resulting multiquantum well heter
Attitudes among hospital physicians to the reporting of adverse drug reactions in Sweden
This study was designed to investigate attitudes to and incentive for reporting adverse drug reactions (ADRs) in general and towards nurses as reporters of ADRs in particular in a sample of hospital physicians. A questionnaire was sent to 1,201 randomly selected hospital physicians. The main factors for the decision to report an ADR were the severity of the reaction, a reaction to a new drug, and
Mental Workload in Aircraft and Simulator During Basic Civil Aviation Training
This study investigated mental workload in basic civil aviation training. Heart rate, eye movement, and subjective ratings from 11 students were collected during simulator and aircraft sessions. Results show high correspondence in psychophysiological reactions between the sessions. For some flight segments, heart rate was consistently lower in the simulator, suggesting higher mental workload in th

Abstract in Polish W artykule przedstawiam ogólne ujęcie relacji wartości. Jako punkt wyjścia przyjmuję szczególny typ relacji wartości, równorzędność, stanowiąca zdaniem Ruth Chang pewną postać porównywalności wartości, która różni się od trzech standardowych postaci porównywalności: lepszości, gorszości i równowartości. Joshua Gert zasugerował niedawno, iż pojęcie równorzędności można wyjaśnić, The paper provides a general account of value relations. It takes its departure in a special type of value relation, parity, which, according to Ruth Chang, is a form of evaluative comparability that differs from the three standard forms of comparability: betterness, worseness and equal goodness. Recently, Joshua Gert has suggested that the notion of parity can be accounted for, if value compariso
Can Mobility Management Campaigning Contribute to Pro-Environmental Behaviour in General? Development of an Analytical Tool
This paper brings to the fore the importance of a holistic approach to attaining a general pro-environmental behavioural change in order to reduce carbon emissions and the need to strive for a spillover of pro-environmental behaviour from one area to another. An adjusted version of the MaxSEM model is developed to capture differences in stages of behavioural change regarding environmental load on
SU-8 Cantilever for Bio/chemical Sensing; Fabrication, Characterisation and Development of Novel Read-out Methods
Here, we present the activities within our research group over the last five yearswith cantilevers fabricated in the polymer SU-8. We believe that SU-8 is an interestingpolymer for fabrication of cantilevers for bio/chemical sensing due to its simple processingand low Young’s modulus. We show examples of different integrated read-out methodsand their characterisation. We also show that SU-8 cantil
Nutrient concentrations in stumps and coarse roots of Norway spruce, Scots pine and silver birch in Sweden, Finland and Denmark
The objective of this study was to evaluate the concentrations of nutrients in stumps and coarse roots in Norway spruce, Scots pine and silver birch in Sweden, Finland and Denmark, and to assess how nutrient concentrations vary with site characteristics, stand age and root size. Concentrations of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sodium (Na) in spruce, p
Polymeric IgA1 controls erythroblast proliferation and accelerates erythropoiesis recovery in anemia
Anemia because of insufficient production of and/or response to erythropoietin (Epo) is a major complication of chronic kidney disease and cancer. The mechanisms modulating the sensitivity of erythroblasts to Epo remain poorly understood. We show that, when cultured with Epo at suboptimal concentrations, the growth and clonogenic potential of erythroblasts was rescued by transferrin receptor 1 (Tf
Progress and stagnation of gender equity: contradictory trends within mathematics research and education in Sweden
During the last decade women in Sweden have reduced men’s lead in participation in mathematics education and in professional careers as mathematicians. However, the development is uneven and slow overall. In some areas and at the highest levels women have increased their participation only marginally. Why, one may ask, is progress so slow after almost twenty years of active work from the Women and
Galectin-3 functions as an opsonin and enhances the macrophage clearance of apoptotic neutrophils
Galectin-3, a beta-galactoside binding, endogenous lectin, takes part in various inflammatory events and is produced in substantial amounts at inflammatory foci. We investigated whether extracellular galectin-3 could participate in the phagocytic clearance of apoptotic neutrophils by macrophages, a process of crucial importance for termination of acute inflammation. Using human leukocytes, we show
A toxicological and dermatological assessment of macrocyclic ketones when used as fragrance ingredients* The RIFM Expert Panel
The macrocyclic ketone (MK) group of fragrance ingredients was evaluated for safety following a complete literature search. For high end users, calculated maximum dermal exposures vary from 0.13% to 1.10%; systemic exposures vary from 0.0005 to 0.0441 mg/kg/day. The MKs had low acute toxicity and no significant repeat dose toxicity. Liver weight and blood biochemistry effects were reversible after
A novel programme to evaluate and communicate 10-year risk of CHD reduces predicted risk and improves patients' modifiable risk factor profile
Aims: We assessed whether a novel programme to evaluate/communicate predicted coronary heart disease (CHD) risk could lower patients' predicted Framingham CHD risk vs. usual care. Methods: The Risk Evaluation and Communication Health Outcomes and Utilization Trial was a prospective, controlled, cluster-randomised trial in nine European countries, among patients at moderate cardiovascular risk. Fol
Proteomic analysis of the LPS-induced stress response in rat chondrocytes reveals induction of innate immune response components in articular cartilage
Activation of toll-like receptors (TLR) in articular chondrocytes has been reported to increase the catabolic compartment, leading to matrix degradation, while the main consequence of TLR activation in monocytic cells is the expression and secretion of components of the innate immune response, particularly that of inflammatory cytokines. The objective of the work reported here was to obtain a more
Measurement of the azimuthal anisotropy for charged particle production in root s(NN)=2.76 TeV lead-lead collisions with the ATLAS detector
Differential measurements of charged particle azimuthal anisotropy are presented for lead-lead collisions at root sNN = 2.76 TeV with the ATLAS detector at the LHC, based on an integrated luminosity of approximately 8 mu b(-1). This anisotropy is characterized via a Fourier expansion of the distribution of charged particles in azimuthal angle relative to the reaction plane, with the coefficients v
Specific ion binding to nonpolar surface patches of proteins
Employing detailed atomistic modeling we study the mechanisms behind ion binding to proteins and other biomolecules and conclude that (1) small, hard ions bind via direct ion pairing to charged surface groups and (2) large, soft ions bind to nonpolar groups via a solvent assisted attraction. Our predictions are in qualitative agreement with bulk solution data and may provide an important clue for
Young employees – securities, risk distribution, and fundamental social rights
Introducing a basis for further development of a risk-security model, this article discusses how such a model could be applied in an analysis of the area of youth employment. The article explores certain aspects of recent youth employment policies as expressed in union policies and in the national labour law of a number of EU Member States. Special attention is paid to national labour law reforms
Brain Routes for Reading in Adults with and without Autism: EMEG Evidence
Reading utilises at least two neural pathways. The temporal lexical route visually maps whole words to their lexical entries, whilst the nonlexical route decodes words phonologically via parietal cortex. Readers typically employ the lexical route for familiar words, but poor comprehension plus precocity at mechanically 'sounding out' words suggests that differences might exist in autism. Combined
