Carbon deposition has a serious effect on the performance of solid oxide fuel cells (SOFCs). An unsteady-state 2D model based on COMSOL software is used to study the carbon deposition process in a planar SOFC. The carbon deposition, catalyst activity, reaction rate and temperature fields are obtained to analyse the mechanism of carbon deposition in the SOFC at different operating time. The effects
It is suggested that cultivars of wheat (Triticum aestivum L.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. Water use efficiency (WUE) is worthy of exploration in this regard. In this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg Nha(-1)) and a plant growth retardant (Chl
Metal nanostructures can transfer electromagnetic energy from femtosecond laser pulses to the near-field down to spatial scales well below the optical diffraction limit. By combining few-femtosecond laser pulses with photoemission electron microscopy, we study the dynamics of the induced few-cycle near-field in individual bowtie nanoantennas. We investigate how the dynamics depend on antenna size
A biologically active protein fraction was isolated from rabbit intestine, purified by one-dimensional SDS-PAGE and stained with Coomassie Brilliant Blue. A predominant band of approximately 110-130 kDa was excised and digested in-gel with trypsin. The resulting peptides were extracted then separated by microbore reversed-phase high-performance liquid chromatography (HPLC). Mass spectrometric data
Based upon earlier experimental work by our group, we have started a human immuno-gene therapy study. The goal is to study the effects of immunisation with autologous tumour cells expressing gene sequences for human interferon-gamma For more than two decades we have sought for efficient treatment against malignant gliomas. Our most successful treatment in the animal models is immuno-gene therapy w
The equilibrium self-diffusion of water contained within the porous structure of three different types of starch, viz. corn, wheat and potato starch was investigated. The samples were exposed to humid air until they reached a certain water content, the value of which was determined from the 1H NMR free induction decays. The water self-diffusion coefficient was determined by means of a p
Exposure to methylene chloride produced a time and concentration related increase in liver weight. The effect was more prominent in female mice than in male. The activity of plasma butyrylcholinesterase (BuChE) increased even more than the liver weight at corresponding exposures, but only in the males. Fatty infiltration was noticeable after exposure to 75 p.p.m. and was more prominent in the fema
This essay contains an analysis of the motives behind the French no to Turkish membership in the EU. By examining different analytical approaches to European integration and by establishing motives, the study seeks to explain why France is against the membership. Two categories of motives are explored, the first relating to domestic constraints, and the second dealing with structural ideational co
Urgent structural change is required in higher education to allow collaboration both within and acrossuniversities so that achieving a rapid sustainability transition can become the overarching and mainpurpose of education, research and work in society. A review of the literature reveals that fragmentation,caused by traditional hierarchical faculty and disciplinary organisation, is a major obstacl
The system of welcoming newly arrived students in Sweden has experienced numerous modifications since its inception. Additionally, because the interpretation of education laws us left to the municipalities and head teachers, the various policies have resulted in a multitude of local practices. Over the years, a very wide range of models for organising newcomer reception have therefore been tried o
Farmers as volunteers in research could potentially provide a rich resource for exploring sustainable agricultural research questions. To discern emerging patterns in citizen science-based studies on topics with relevance for sustainable agriculture, and reveal salient challenges and opportunities for conducting such studies, we conducted a systematic literature review of 27 peer-reviewed articles
Despite continued efforts by educators, UN declarations and numerous international agreements, progress is still limited in handling major global challenges such as ecosystem collapse, accelerating climate change, poverty, and inequity. The capacity to collaborate globally on addressing these issues remains weak. This historical review of research on global learning for sustainable development (GL
I dagsläget äger nästan alla vuxna svenskar finansiella instrument. Det är vidare allmänt känt att sparande i finansiella instrument inte är helt riskfritt. För många individer är besparingarna väldigt viktiga, samtidigt som många saknar den kunskap som krävs för att investera i finansiella instrument. Behovet av finansiell rådgivning har därför ökat kraftigt, varför det får anses oroväckande att Almost all Swedish adults own financial instruments. It is well known however that investing in financial instruments is not risk free. Furthermore, these investments are often very important for many individuals, but most people lack the necessary knowledge required to invest in financial instruments. There has therefore been a strong increase in the need for financial advisers. With regard to th
Despite much research and applications, glass material and its use in buildings is still challenging for engineers due to its inherent brittleness and characteristic features such as sensitivity to stress concentrations, reduction in strength over time and from temperature, and breakage due to the stresses that may build up because of thermal gradients. This paper presents the results of an origin
Generally, droplet velocity in liquid-liquid two-phase flow in microchannel is obtained via droplet displacement and time interval precise determination in sequential photos/videos. The precision is tightly related to shutter speed of the camera. In this paper, a novel method called direct image method is proposed to predict the droplet velocity. The droplet velocity can be easily obtained in one
Spatiotemporal analysis of long-term changes in air temperature is of prime importance for climate change research and the development of effective mitigation and adaptation strategies. Although there is considerable research on air temperature change across the globe, most of it has been on linear trends and time series analysis of nonlinear trends has not received enough attention. Here, we anal
This article discusses theoretical and practical aspects of real-time brain computer interface control methods based on Bayesian statistics. The theoretical aspects include how the data from the brain computer interface can be translated into a Gaussian mixture model that is used in the Bayesian statistics-based control methods. The practical aspects include how the control methods improve the per
The Accord on Fire and Building Safety in Bangladesh (the Accord) is generally seen as a positive development in ensuring that Bangladeshi garment industry workers have access to safe working conditions. A central structural difference between the Accord and earlier corporate social responsibility (CSR) initiatives is that the Accord takes the form of an enforceable contract that directly connects
