Stages of change in audiology : comparison of three self-assessment measures

Objective: In a clinical setting, theories of health behaviour change could help audiologists and other hearing health care professionals understand the barriers that prevent people with hearing problems to seek audiological help. The transtheoretical (stages of change) model of health behaviour change is one of these theories. It describes a person’s journey towards health behaviour change (e.g.

An estimated 400-800 million tons of prey are annually killed by the global spider community

Spiders have been suspected to be one of the most important groups of natural enemies of insects worldwide. To document the impact of the global spider community as insect predators, we present estimates of the biomass of annually killed insect prey. Our estimates assessed with two different methods suggest that the annual prey kill of the global spider community is in the range of 400-800 million

Is genetic diversity more important for terpene emissions than latitudinal adaptation? : Using genetically identical trees to better understand emission fluctuations across a European gradient

Biologiskt flyktiga organiska ämnen (BVOCs) är spårämnen förutom CO2 och CH4 som produceras och släpps ut av växter. Termen innehåller tusentals olika ämnen i varierande former och storlekar och där ämnena har korta atmosfäriska livstider. Några av de vanligaste BVOC grupperna kallas isopren, monoterpener och sesquiterpener. Växterna använder sig av BVOCs för att kommunicera med varandra, attraherBiogenic volatile organic compounds (BVOCs) are trace gases other than CO2 and CH4 produced and emitted by the vegetation. The group consists of thousands of compounds in various shapes and sizes and with short atmospheric lifetimes. Some of the most common BVOC groups are called isoprene, monoterpenes and sesquiterpenes. For the plant, the emission of BVOCs is used for plant communication, attrac

Hydrodynamics and mass transfer in liquid-liquid non-circular microchannels : Comparison of two aspect ratios and three junction structures

Hydrodynamics and mass transfer in liquid-liquid slug flow inside a square microchannel (MC-1, aspect ratio 1) and a rectangular microchannel (MC-2, aspect ratio 2) with identical hydraulic diameter (400 µm) were investigated experimentally. The results showed that the overall volumetric mass transfer coefficient (KLa) in MC-2 was 16.2% lower than that in MC-1 due to enlargement of the dispersed p

The transcription factor MYB29 is a regulator of alternative oxidase1a

Plants sense and integrate a variety of signals from the environment through different interacting signal transduction pathways that involve hormones and signaling molecules. Using ALTERNATIVE OXIDASE1a (AOX1a) gene expression as a model system of retrograde or stress signaling between mitochondria and the nucleus, MYB DOMAIN PROTEIN29 (MYB29) was identified as a negative regulator (regulator of a

Recent applications of synchrotron radiation and neutrons in the study of soft matter

The broad range of applications of synchrotron and neutron scattering in the investigation of soft condensed matter is reviewed. Appropriate combinations of these techniques allow probing the structure and dynamics of these complex systems from sub-nm to micron size scales and picoseconds to seconds and longer time ranges. Applications include a myriad of systems such as polymers, colloids, surfac

Inactivation of Mitochondrial Complex I Induces the Expression of a Twin Cysteine Protein that Targets and Affects Cytosolic, Chloroplastidic and Mitochondrial Function

At12Cys-1 (At5g64400) and At12Cys-2 (At5g09570) are two closely related isogenes that encode small, twin cysteine proteins, typically located in mitochondria. At12Cys-2 transcript is induced in a variety of mutants with disrupted mitochondrial proteins, but an increase in At12Cys protein is only detected in mutants with reduced mitochondrial complex I abundance. Induction of At12Cys protein in mut

Stimuli-controlled self-assembly of diverse tubular aggregates from one single small monomer

The design and synthesis of new stimuli-responsive hydrogen-bonding monomers that display a diversity of self-assembly pathways is of central importance in supramolecular chemistry. Here we describe the aggregation properties of a simple, intrinsically C2-symmetric enantiopure bicyclic cavity compound bearing a terminally unsubstituted ureidopyrimidinone fragment fused with a pyrrole moiety in dif

Looking is buying. How visual attention and choice are affected by consumer preferences and properties of the supermarket shelf

There is a battle in the supermarket isle, a battle between what the consumer wants and what the retailer and others want her to see, and subsequently to buy. Product packages and displays contain a number of features and attributes tailored to catch consumers' attention. These are what we call external factors comprising the visual saliency, the number of facings, and the placement of each produc

Tensile behavior of single-crystal nano-sized Cu beams – Geometric scaling effects

In this paper the mechanical response of single-crystal nano-sized Cu beams of different sizes, loaded in displacement controlled tension under constant strain rate is investigated through 3D molecular dynamic simulations using the free-ware LAMMPS. The effects from pure geometric scaling are determined for two different crystallographic orientations of the lattice. Stress–strain curves were recor

Primärvårdens funktion, organisation och ekonomi - en litteraturöversikt : Rapport till utredningen En nationell samordnare för effektivare resursutnyttjande inom hälso- och sjukvården (S 2013:4)

Svensk hälso- och sjukvård har i ett historiskt perspektiv dominerats av investeringar i specialistvård och sjukhus. Även om intresset för primärvården har ökat kvarstår många frågor om hur man bäst organiserar verksamheten och vilken betydelse primärvården har för hälso- och sjukvårdens samlade kvalitet och effektivitet.

Plasma metabolite profiles, cellular cholesterol efflux, and non-traditional cardiovascular risk in patients with CKD

BACKGROUND: Patients with chronic kidney disease (CKD) experience high rates of atherosclerotic cardiovascular disease and death that are not fully explained by traditional risk factors. In animal studies, defective cellular cholesterol efflux pathways which are mediated by the ATP binding cassette transporters ABCA1 and ABCG1 are associated with accelerated atherosclerosis. We hypothesized that c

The need for robust, consistent methods in societal exergy accounting

Studies of societal exergy use have the common aim of tracing the flow of exergy along society, and are used to gain insights into the efficiency of energy use and linkages to economic growth. However, their methodological approaches vary greatly, with significant impacts on results. Therefore, we make a review of past studies to identify, synthesize and discuss methodological differences, to cont

Personuppgifter som betalningsmedel

Personuppgifter som betalningsmedelDen här rapporten visar hur konsumenternas data kommit att få ett centralt värde i den digitala ekonomin. Förändringen väcker frågor om hur väl konsumentskyddet därmed står sig i förhållande till detta. Studien beskriver och analyserar de konsumentrelaterade utmaningar som den växande användningen av personuppgifter som en form av betalningsmedel medför. I studie

Exposure to inorganic arsenic and gene expression in peripheral blood

Arsenic is an established carcinogen and a risk factor for several non-malignant diseases. Mechanisms of arsenic toxicity may include interference with gene expression. The impact of arsenic exposure on gene expression was evaluated in women (n = 80) living in the Puna of the northern Argentinian Andes with varying concentrations (10–1251 μg/L) of arsenic in drinking water.

Planting to feed the city? : Agricultural production, food security and multi-spatial livelihoods among urban households in Ghana

The 2010 population and housing census in Ghana revealed that more than half of the Ghanaian population lived in urban centers. Critical to the phenomenon of urbanization is the question of how to sustainably feed the urban population especially the urban poor as rapid urbanization has the tendency to urbanize poverty. This has led to renewed policy debate about the implications of farming in citi
