A novel tool-use mode in animals : New Caledonian crows insert tools to transport objects

New Caledonian crows (Corvus moneduloides) rely heavily on a range of tools to extract prey. They manufacture novel tools, save tools for later use, and have morphological features that facilitate tool use. We report six observations, in two individuals, of a novel tool-use mode not previously reported in non-human animals. Insert-and-transport tool use involves inserting a stick into an object an

Migraine co-existing tension-type headache and neck pain : Validation of questionnaires

Background and aim: Migraine often includes co-existing tension-type headache (TTH) and neck pain (NP). Multiple headache questionnaires assessing headache impact have been described previously; however, none of the existing questionnaires have been designed to cover migraine with co-existing TTH and NP. Therefore a new questionnaire was developed to measure these co-morbidities. The aim was to de

Group concept mapping for evaluation and development in nursing education

The value of course evaluations has been debated since they frequently fail to capture the complexity of education and learning. Group Concept Mapping (GCM), a participant-centred mixed-method was explored as a tool for evaluation and development in nursing education and to better understand students' learning experiences, using data from a GCM-based evaluation of a research training assignment in

Fall Risk and Its Associated Factors among Older Adults without Home-Help Services in a Swedish Municipality

During preventive home visits, the purpose of this study was to identify the prevalence of fall risk and any associated factors. Participants (n = 1471) were cognitively sound community-dwelling older adults (≥ 70 years) without home-help service, living in a Swedish municipality. The Downton Fall Risk Index and nine single items were used. Tiredness/fatigue, age ≥ 80, inability to walk 1 hr, inab

Count rate characteristics and image distortion in preclinical PET systems during intratherapeutic radiopharmaceutical therapy imaging

Positron emission tomography (PET) may provide important information on the therapeutic response of radiopharmaceutical therapy (RPT) during therapy. The radiation emission from the RPT radionuclide may disturb the coincidence detection and impair the image resolution. In this study we tested the feasibility to perform intratherapeutic PET on three preclinical PET systems.METHODS: Using (22)Na poi

The Sports-Related Injuries and Illnesses in Paralympic Sport Study (SRIIPSS) : a study protocol for a prospective longitudinal study

BACKGROUND: Paralympic sport provides sporting opportunities for athletes with a disability, with the Paralympic Games as the main event. Participation in sport is, however, associated with a significant risk for sustaining injuries and illnesses. Our knowledge of sports-related injuries and illnesses in Paralympic sport is very limited and there are no large-scale epidemiological cohort studies.

Environmental and climate reconstruction of the late-glacial-Holocene transition from a lake sediment sequence in Aubrac, French Massif Central : Chironomid and diatom evidence

The analysis of fossil chironomid and diatom assemblages from a sedimentary record from Les Roustières peat bog (Massif Central, France, 1196 m asl) allows the reconstruction of past environmental and climate changes during the late-glacial and early Holocene. Chironomid assemblages showed that the infilling of the palaeolake had commenced during the Oldest Dryas (GS-2b) as suggested by the rapid

Zeolite Beta Formation from Clear Sols : Silicate Speciation, Particle Formation and Crystallization Monitored by Complementary Analysis Methods

The formation of silicate nanoaggregates (NAs) at the very early stages of precursor sols and zeolite beta crystallization from silicate nanoparticles (NPs) are investigated in detail using a combination of different analysis methods, including liquid-state 29Si, 27Al, 14N, and 1H NMR spectroscopy, mass spectrometry (MS), small-angle X-ray scattering (SAXS), X-ray diffraction (XRD), and transmissi
