Background: Health care providers in many countries have delivered interventions to improve physical activity levels among their patients. Thus far, less is known about the population's interest to increase their physical activity levels and their opinion about the health care provider's role in physical activity promotion. The aims of this paper were to investigate the self-reported physical acti
Elastic simulations of single-crystal copper nanobeams, of different cross section sizes and with crystallographic orientations [100] and [110] along their length directions, have been performed applying tensile mechanical loading. The molecular dynamics code LAMMPS was employed for the simulations. The Poisson's ratio, which is one of the fundamental measures of the elastic deformation behaviour
This paper explores the effects of communication in market entry games experimentally. It is shown that communication increases coordination success substantially and generate inferior outcomes for consumers when market entry costs are symmetric. Such effects are not observed when costs are asymmetric, since asymmetries provide a tacit coordination cue used by experienced players (as a substitute
Background. Most survival studies of the elderly population have set their baselines for first examinations between 60 and 80 years. The rapidly increasing numbers of exceptionally old persons call for knowledge about determinants of exceptional survival. Methods. The Swedish Centenarian Study followed 100 centenarians from the age of 100 to death of the entire cohort, by age I I I years. A biomed
Background: There is a need for a rapid and cost-effective evaluation of the effects of different human papillomavirus (HPV) vaccination strategies. Sexually active adolescents are a preferred target group for monitoring, as effects on HPV prevalence would be measurable shortly after implementation of vaccination programs. Methods: The Swedish Chlamydia trachomatis testing program offers free Chla

The project is an initiative by the Stockholm Police. Collaborating partners in the project are the Swedish Coast Guard, Region Northeast; the Helsinki Police; the Gulf of Finland Coast Guard District; the Police and Border Guard Board in Estonia; the State Border Guard of the Republic of Latvia; and the State
P>The structure of GaMnAs nanowires (NW) with nominal Mn concentration of up to 7 at% was investigated by transmission electron microscopy. The (Ga,Mn)As NW were grown on epiready GaAs(001) n-type wafers by molecular beam epitaxy. The crystal structure of the NW was determined to be zinc-blende. NW with Mn concentrations lower than 5 at% grow along the << 111 >> direction. NW with higher Mn concen
The idea of a usable methodology, one which will both retain the idea of 'a subject' at the heart of research and also recognize that in historical research the researcher necessarily has to work with textual remains, is discussed. Piecing this together is explored in relation to researching correspondences and other archival materials relating to two women who were fin de siecle prostitutes and a
Nowadays, soil diversity is accessed at molecular level by the total DNA extraction of a given habitat. However, high DNA yields and purity are difficult to achieve due to the co-extraction of enzyme-inhibitory substances that inhibit downstream applications, such as PCR, restriction enzyme digestion, and DNA ligation. Therefore, there is a need for further development of sample preparation method
Pulsed electric fields in combination with vacuum infusion have been utilized to impregnate cells with trehalose, aiming at substantially improving the freezing tolerance of spinach leaves. Spinach samples were first treated with ten trains of bi-polar, rectangular electric field pulses with a nominal electric field strength of 580 V/cm and immediately immersed in a 40% (w/w) solution of trehalose
Background: The relationship between Helicobacter pylori infection and pancreatic cancer has been investigated in three previous studies with contradictory results. The aim of the present study was to investigate the association between H. pylori seropositivity and the risk for pancreatic cancer in a nested case-control study within a population based cohort. Methods: Selected birth- year cohorts
The effects induced by the deposition of Li on 1 and 0 ML graphene grown on SiC(0001) and after subsequent heating were investigated using low-energy electron microscopy (LEEM) and x-ray photo-emission electron microscopy (XPEEM). For 1 ML samples, the collected photoelectron angular distribution patterns showed the presence of single pi-cones at the six equivalent K-points in the Brillouin zone b
Recent developments in the field of genetic divergence and speciation focus more on diversifying processes than on geographic mode of speciation (i.e. allopatric versus sympatric). Some of these new theories concern speciation driven by conflicts between the sexes. Even though it is well known that the two reproductive functions in plants can have different selective optima, sexual selection in pl
Background: Rheumatic diseases commonly affect joints and other structures in the hand. Surgery is a traditional way to treat hand problems in inflammatory rheumatic diseases with the purposes of pain relief, restore function and prevent progression. There are numerous measures to choose from, and a combination of outcome measures is recommended. This study evaluated if instruments commonly used i
This paper provides an ex-post assessment of the climate and energy policy developments in Chile emerging from a neoliberal economic model, during the period 1971-2007. First, correlation and regression analyses were performed to analyse historical CO2 emissions as a product of demographic, economic and energy-wide drivers. Then I estimate indicators related to CO2 emissions, energy use and econom
Analyses assessed the degrees to which personality accounts for associations between marital quality and parenting and mediates genetic contributions to these relationships. Participants included 318 male and 544 female same-sex twin pairs from the Twin and Offspring Study in Sweden. All twins completed self-report measures of marital quality and personality (anxiousness, aggression, sociability).
Gene expression profiling studies initially enabled diffuse large B-cell lymphoma to be divided into germinal center and activated B-cell-like subtypes, which define high-and low-risk patient groups when treated with chemotherapy. Attempts to reproduce the prognostic classification immunohistochemically have, however, provided inconsistent results. The aim of this study was to determine whether mo
Photoluminescence (PL) of organo-metal halide perovskite semiconductors can be enhanced by several orders of magnitude by exposure to visible light. We applied PL microscopy and super-resolution optical imaging to investigate this phenomenon with spatial resolution better than 10 nm using films of CH3NH3PbI3 prepared by the equimolar solution-deposition method, resulting in crystals of different s
