In this report we explore the structural and optical properties of GaAs/AlGaAs heterostructure nanowires grown by metalorganic vapour phase epitaxy using gold seed-particles. The optical studies were done by low-temperature cathodoluminescence (CL) in a scanning electron microscope (SEM). We perform a systematic investigation of how the nanowire growth-temperature affects the total photon emission

In the circuits of culture there are a multitude of representations in circulation. These representations are derived from a range of media products such as guidebooks and tourist brochures. Furthermore, these media products and representations continuously converge with each other. The question, then, is what representations are contained within these converged media products. This article theref

Background: The International Psychogeriatric Association Task Force on Mental Health Services in Long-Term Care Facilities aims to support and strengthen mental health services in the long-term care sector. The purpose of this paper is to identify broad principles that may underpin the drive towards meeting the mental health needs of residents of long-term care facilities and their families, as w

Multiple visual pigments, prerequisites for color vision, are found in arthropods, but the evolutionary origin of their diversity remains obscure. In this study, we explore the opsin genes in five distantly related species of Onychophora, using deep transcriptome sequencing and screening approaches. Surprisingly, our data reveal the presence of only one opsin gene (onychopsin) in each onychophoran

The source contributions to carbonaceous PM2.5 aerosol were investigated at a European background site at the edge of the Po Valley, in Northern Italy, during the period January-December 2007. Carbonaceous aerosol was described as the sum of 8 source components: primary (1) and secondary (2) biomass burning organic carbon, biomass burning elemental carbon (3), primary (4) and secondary (5) fossil

In the mid-nineteenth century, Karl Marx issued several critiques of political economy writings stressing the exclusive duality of states and the national economies. He argued that capitalism had characteristic features quite apart from those shaped by the idiosyncrasies of national economies. In the first part of this article, we critique the contemporary state-centered explanations for the indus

Research related to oral health in people with mental health problems may deepen our understanding of the quality of life of such individuals. This study aimed to investigate the relationship between oral status, health perceptions and life satisfaction, and their impacts on oral health-related quality of life (OHQoL). Data were collected from 113 patients in outpatient psychiatric care using a st

A diode-laser-based setup was used for extinction measurements at various heights in two flat premixed sooting ethylene/air flames in order to investigate the wavelength dependence of the extinction. Twelve laser wavelengths were used in the interval 405-1064 nm, and with this setup, a sensitivity of similar to 10(-4) was achieved for the extinction. Soot volume fractions inferred from the extinct

A search for a Higgs boson has been performed in the H -> WW -> l nu jj channel in 1.04 fb(-1) of pp collision data at root s = 7 TeV recorded with the ATLAS detector at the Large Hadron Collider. No significant excess of events is observed over the expected background and limits on the Higgs boson production cross section are derived for a Higgs boson mass in the range 240 GeV < m(H) < 600 GeV. T

This paper deals with the role of a journal's publisher country in determining the expected citation rates of the articles published in it. We analyze whether a paper has a higher citation rate when it is published in one of the large publisher nations, the U.S., U.K., or the Netherlands, compared to a hypothetical situation when the same paper is published in journals of different origin. This wo

Thermal adaptation of gross primary production and ecosystem respiration has been well documented over broad thermal gradients. However, no study has examined their interaction as a function of temperature, i.e. the thermal responses of net ecosystem exchange of carbon (NEE). In this study, we constructed temperature response curves of NEE against temperature using 380 site-years of eddy covarianc

Pharmaceutical residues are increasingly detected in environmental and biological samples, some at levels known to adversely affect non-target organisms; however, less is known of how these organism-level effects relate to the ecology of aquatic systems. Foraging processes may be used as behavioral endpoints that link effects on individuals to the population and community levels, enabling risk ass

Background Both patient survival and the proportion of patients diagnosed with thin cutaneous malignant melanoma (CMM) have been steadily rising in Sweden as in most Western countries, although the rate of improvement in survival appears to have declined in Sweden at the end of the last millennium. Objectives To analyse the most recent trends in the distribution of tumour thickness (T category) as

Epigenetic information includes heritable signals that modulate gene expression but are not encoded in the primary nucleotide sequence. We have studied natural epigenetic variation in three allotetraploid sibling orchid species (Dactylorhiza majalis s.str, D. traunsteineri s.l., and D. ebudensis) that differ radically in geography/ecology. The epigenetic variation released by genome doubling has b

Inconspicuous consumption, the habitual use of resources in daily routines, poses a challenge to sustainable consumption. For example, laundry is often the most environmentally demanding stage of clothing’s life cycle, consuming significant quantities of water, energy and chemicals. Laundry thus provides a prime example of inconspicuous consumption, from which to consider sustainability transition

Helianthemum nummularium (L.) Mill. has two subspecies in southern Scandinavia, which differ in an indumentum character that is inherited as a Mendelian gene with two alleles. The dominant allele is the genetic basis for the key character of subsp. obscurum (absence of a dense felt of stellate hairs on the abaxial surface of the leaf), whereas the recessive allele is the genetic basis for the key

OBJECTIVES: Rheumatoid arthritis (RA) is less common among men than women, and sex hormones have been suggested to play a part in the pathogenesis. Lower levels of testosterone have been demonstrated in men with RA, but it is not known if these changes precede the disease. METHODS: In a nested case-control study, using information and blood samples from a population-based health survey, we identif

Objective: To investigate the hypothesis that cardiovascular risk factors increase the likelihood of future osteoarthritis (OA)-related arthroplasty in adult men and women. Methods: Baseline cohort data on cardiovascular risk factors [age, socio-economic class, family history, obesity, smoking, glucose, cholesterol, blood pressure, and early cardiovascular disease (CVD) history] were linked to cli

Type 2 diabetes mellitus (T2DM) and HER2 are associated with cancer although the role of HER2 in T2DM is not well defined. Our aim was to investigate the association between HER2 levels and T2DM and whether that association was different in Swedish people born in Iraq or Sweden.

This paper explores the attitude-behaviour gap from an identity perspective in order to better understand why tourists act sustainably at "home" but not when "away". The majority of tourism-related CO2 emissions stems from transport. Behavioural change is a possible way to reduce those emissions. However, research indicates that instigating behavioural change within tourism is problematic, because
