Premixed ethyl formate + air flames have been investigated at atmospheric pressure and initial temperatures from 298 to 348 K. The burning velocities were determined using the heat flux method for equivalence ratios from 0.6 to 1.5 and were compared with limited data available in the literature and with measurements for the C3H6O2 isomer, methyl acetate, obtained under the same conditions. In ethy
Fluctuations of thermodynamic observables, such as heat and work, contain relevant information on the underlying physical process. These fluctuations are however not taken into account in the traditional laws of thermodynamics. While the second law is extended to fluctuating systems by the celebrated fluctuation theorems, the first law is generally believed to hold even in the presence of fluctuat
Opsins allow us to see. They are G-protein-coupled receptors and bind as ligand retinal, which is bound covalently to a lysine in the seventh transmembrane domain. This makes opsins light-sensitive. The lysine is so conserved that it is used to define a sequence as an opsin and thus phylogenetic opsin reconstructions discard any sequence without it. However, recently, opsins were found that functi
This paper considers the concept and practice of entrepreneurial leadership in the academe. After a small introduction to the research in the emerging field of entrepreneurial leadership, we note many substantial differences between academic entrepreneurs and the general class of entrepreneurs so as to motivate our focus on the academic community. We then provide a brief narrative on some strands
Blended and online learning environments continue to grow, transforming higher education. The motivation behind this study is to explore blended and online learning environments, from the perspective of students, through the lens of Activity Theory (AT). Based on 12 virtual semi-structured interviews with Master's (MSc) students at one University in England, the paper sheds light onto some of the
Vi lever i en på många sätt global värld. Då behöver också vår historieskrivning frigöra sig från sitt gamla beroende av nationen och Europa. På senare tid har därför ämnet globalhistoria blivit allt viktigare, men medan somligt har skrivits om det på svenska har betydligt mindre skrivits i det.Natur & Kulturs globalhistoria i två band är därför något av en pionjärsatsning, ett experiment.Ett

Periprostheteic joint infection (PJI) is a rare complication of arthroplasty with severe consequences for the affected patients. PJI most often necessitates additional surgery and prolonged courses of antibiotic treatment, leading to worse functional results and increased societal costs. Evaluating treatment of PJI as well as preventive efforts are essential to increase our understanding of PJI an
