An issue in sports contexts as well as other educational contexts has been whether feedback on the personal level, often in the shape of praise, contributes to the progression of the practitioners’ skills. This article examines whether PEH teachers’ feedback on the personal level, using the word good, in specific contexts actually can contribute to crucial progress and empowerment of the pupils/pr
Recently, to reach zero emission levels, some new energy systems based on fuel cells have been developed. This paper presents a review of investigations of these systems by thermodynamics performance, mainly, energy and exergy analysis. With energy analysis, the performance of an energy conversion system cannot be effectively and accurately evaluated. But exergy analysis complements and reinforces
Background: Musculoskeletal pain and its risk factors are rarely assessed in studies on adolescent athletes. The aim was to identify risk factors at baseline that were associated with the persistence or development of musculoskeletal pain at a two-year follow-up in adolescent sport school students, and to study cross-sectional associations at follow-up between musculoskeletal pain and sports perfo
Accurate extrinsic calibration of wide baseline multi-camera systems enables better understanding of 3D scenes for many applications and is of great practical importance. Classical Structure-from-Motion calibration methods require special calibration equipment so that accurate point correspondences can be detected between different views. In addition, an operator with some training is usually need
Industrial processes currently account for a signifcant share (25–35 %) of the world’s total energy demand and related emissions. During recent years, the amount of low-carbon electricity from renewable energy sources (such as wind and solar) has increased continuously. Tere is therefore an increasing interestin electrifcation of industrial processes in order to achieve long-term decarbonisation g
The electrochemical communication between microorganisms and electrodes has substantial implications both for basic understanding of biological electron transfer as well as in diverse applications, such as, microbial electrochemical system (MES), microbial biosensors and in production of valuable chemicals. In these systems the extracellular electron transfer (EET) from microbial metabolism to ele
Moraxella catarrhalis is a Gram-negative human mucosal commensal and pathogen. It is a common cause of exacerbation in chronic obstructive pulmonary disease (COPD). During the process of infection, host colonization correlates with recognition of host molecular patterns. Importantly, in COPD patients with compromised epithelial integrity the underlying extracellular matrix is exposed and provides

It has repeatedly been shown that consumers consider the higher price of organic produce to be a barrier to buying organic food products. The present paper therefore asks whether organic consumption affects consumers’ actual total food expenditures. Food purchase data for a panel of Danish households during 2006–2014 were used to compare the total food expenditures of different organic household s
