The application of one-dimensional nanofibers in the fabrication of an electrode greatly improves the performance of solid oxide fuel cells (SOFCs) due to its advantages on electron transfer and mass transport. Various mixed ionic-electronic conducting materials with perovskites and Ruddlesden-Popper-type metal oxide structures are successfully electrospun into nanofibers in recent years mostly in

Energy security, climate change and air pollution are all motivations for further development of fuel cells. Still, technical problems relating to water management, continue to hinder the marketability of polymer electrolyte fuel cells (PEFCs). The impact of dynamic contact angle (CA) boundary conditions, according to the Kistler model, is evaluated in this paper with the VOF approach, focusing on

This study aims to better understand entrepreneurial learning in the context of venture acceleration programs.A qualitative research strategy was used based on multiple in-depth interviews with 21 lead entrepreneurs complemented with participatory observations and secondary sources. The data were inductively analysed following the Gioia methodology (Gioia et al., 2012).The authors build on experie

HYPOTHESIS: The clinical and physiological features of patients with short segments of columnar-lined esophagus (CLE) with and without intestinal metaplasia (IM) are distinct.DESIGN: Retrospective case series.SETTING: University tertiary referral center.PATIENTS: Sixty-five consecutive patients with a 2-cm or shorter length of endoscopically visible CLE.INTERVENTIONS: The type of CLE and the prese

BACKGROUND: This study evaluates the efficiency and safety of two methods of chest drainage after uncomplicated oesophagectomy.METHODS: A prospective randomized study between active suction drainage and passive chest drainage was carried out in 101 patients who underwent gastric pull-up oesophagectomy.RESULTS: No difference in the prevalence of pneumothorax during treatment was noted between the a

Drop breakup in high-energy emulsification is often modelled using a population balance equation (PBE) framework. For cases with high emulsifier to disperse phase concentration, the PBE is dominated by the fragmentation term. Since there are no analytical solutions to the continuous PBE for physically reasonable fragmentation rate expressions, a discretization is often needed to evaluate the PBE,

Misstänksamheten mot det nyuppfunna margarinet var nära att leda till ett totalförbud i Sverige kring sekelskiftet 1900. Ännu idag florerar fördomar mot ”konstsmöret”, som måste betraktas som ett av våra mest politiskt kontroversiella livsmedel.

Understanding ethical buying behaviour is an important component in the study of sustainability. Multiple studies on fair trade have been conducted in established markets in Europe, with limited but increasing research in emerging markets. This study used a questionnaire survey to investigate South African consumers’ ethical buying behaviour, using conjoint analysis to imitate the multi-attribute

Radar technology has developed rapidly during the last century. Besides its initial use for military, it is nowadays also applied for many civil applications. Improvements in circuit technology make integrated radar sensors possible, allowing a significant reduction of the production cost. Integrated radio circuits in the low gigahertz range are widely available, not least driven by wireless commu

Public transport is an important part of the transition to a more sustainable future. The increasingly market-oriented public transport companies today market themselves with a wealth of messages in multiple channels such as direct mail, websites and apps. This communication is part of the influence that the (potential) traveler is exposed to, yet little research and testing is carried out in orde
