Practice theory roughly argues that the material world and the cultural world continuously interact and co-constitute one another. However, existing research methods on consumer behaviors tend to separatethese two dimensions and show a preference toward concentrating on only one of them. Video ethnography as a medium has the potential to capture these two worlds—to combine the symbolic and materia
This research examines the practices of consumers that are made possible by a 'low-end' street, and how these shopping practices in turn shape and maintain a high street at the urban margins. It locates itself within the academic inquiries of cultural geographies of retail.Södergatan is the field of the study, the main shopping street in the stigmatized southern part of city of Helsingborg in Swed
We are seeing today an increased interest in ethics, the environment, and social responsibility at the same time as the individual is expected, in different ways, to realize him-/herself through consumption. These interests coincide with the establishment of ethical markets for re-use and second-hand. In this paper we investigate and map out the ethical shopping spaces in Helsingborg, and how thes
Hydrodynamic cavitation that occurs inside valves not only increases the energy consumption burden of the whole piping system but also leads to severe damages to the valve body and the piping system with a large economic loss. In this paper, in order to reduce the hydrodynamic cavitation inside globe valves, effects of valve body geometrical parameters including bending radius, deviation distance,
The epidermis of aerial plant organs is thought to be limiting for growth, because it acts as a continuous load-bearing layer, resisting tension. Leaf epidermis contains jigsaw puzzle piece-shaped pavement cells whose shape has been proposed to be a result of subcellular variations in expansion rate that induce local buckling events. Paradoxically, such local compressive buckling should not occur
We ask what caused poverty to decline in Brazil over the last decade. Our contribution lies in the introduction of a structural change perspective to assess the evolution of poverty by considering the sectoral impact of growth and the social policies at the federal, state and municipal level. We confirm previous findings in the literature that the service sector rather than agriculture contributes
Apicobasal polarity is known to affect epithelial morphogenesis and cell differentiation, but it remains unknown how these processes are mechanistically orchestrated. We find that ligand-specific EGFR signalling via PI(3)K and Rac1 autonomously modulates apicobasal polarity to enforce the sequential control of morphogenesis and cell differentiation. Initially, EGF controls pancreatic tubulogenesis
The oomycete Phytophthora infestans is the most harmful pathogen of potato. It causes the disease late blight, which generates increased yearly costs of up to one billion euro in the EU alone and is difficult to control. We have performed a large-scale quantitative proteomics study of six P. infestans life stages with the aim to identify proteins that change in abundance during development, with a
A direct correlation between the reaction activity and the surface structure of a catalyst is generally needed to better understand the mechanisms behind the heterogeneous catalysis process. In this work, we employed planar laser-induced fluorescence (PLIF) to spatially resolve the CO2 distribution just above a Pd(100) surface, and simultaneously monitored the optical reflectance of the surface, d
The interaction of water vapor and sulfur dioxide (SO2) with single crystal cuprous oxide (Cu2O) surfaces of (100) and (111) termination was studied by photoelectron spectroscopy (PES) and density functional theory (DFT). Exposure to near-ambient pressures of water vapor, at 5 × 10-3 %RH and 293 K, hydroxylates both Cu2O surfaces with OH coverage up to 0.38 copper monolayers (ML) for (100) and 0.2
Hallmarks of type 2 diabetes (T2D) include elevated blood glucose and free fatty acids (FFAs) as a result of impaired β cell insulin secretion and decreased β cell mass. The glucose-stimulated insulin secretion (GSIS) in β cells is triggered by depolarization-evoked Ca2+ entry through voltage-gated Ca2+ (CaV) channels. The majority of CaV channels are believed to reside in cholesterol-rich membran
