Friendship is an undertheorized but increasingly important relationship in late modernity. In this article, the authors present findings from two ongoing research projects about friendship, gender and age in contemporary Sweden. They argue that discourses about gender and friendship are highly relevant for how friendship is conceptualized both among men and women, but that culturally ingrained con
Molecularly imprinted materials, prepared using self-assembly imprinting protocols using only non-covalent interactions, can be used as chromatography media in aqueous phase. The recognition properties are highly dependent on the interacting species used in the imprinting protocol. Ionic interactions, together with strong hydrogen bonding, represent useful means of obtaining recognition. With incr
Energy Performance Certificates are currently one of the most extensive data sources about the energy performance of the EUs building stock and consequently provide support for researchers and policy makers in energy regulation. As Energy Performance Certificates are being renewed, there are new possibilities to study energy performance development over time and to evaluate the building-specific e
An uncommon non-monotonic behavior of the temperature dependence of adiabatic laminar burning velocity has been found in over-rich methane+air flames at equivalence ratio, ϕ = 1.4. To find out the universality and reasons of this turning point, methane, ethane and propane + air flames are studied both experimentally by the heat flux method and numerically using GRI-mech, USC-mech, UCSD-mech, FFCM
In this study, the influence of various air inlet angles on the heat transfer and flow friction characteristics of a 2-row plain finned oval tube heat exchanger is analyzed by experimental and numerical methods. The experimental results show that an air inlet angle 45° provides the best heat transfer performance, and an air inlet angle 90° provides the smallest pressure drop, while an air inlet an
The ALICE collaboration performed the first rapidity-differential measurement of coherent J/ψ photoproduction in ultra-peripheral Pb–Pb collisions at a center-of-mass energy sNN=5.02 TeV. The J/ψ is detected via its dimuon decay in the forward rapidity region (−4.0
During nine months, nineteen hairdressers every second/third month switched the use between a blow dryer with traditional design and one with a new design. The new blow dryer had the possibility to change between two opposite directed air flows. Every second/third month arm inclination angle and upper trapezius muscle activity were measured a whole workday, and during blow-drying in the laboratory
Sewers that constitute the main part of wastewater systems can be used as pretreatment units of wastewater treatment plants. The authors aim to increase the treatment efficiency of sewers by optimization. A hydraulic model is written and validated. A quality calculation section is added to the model according to the Wastewater Aerobic/Anaerobic Transformations in Sewers (WATS) method, and it is ca
