Background: The commercialization of second-generation bioethanol has not been realized due to several factors, including poor biomass utilization and high production cost. It is generally accepted that the most important parameters in reducing the production cost are the ethanol yield and the ethanol concentration in the fermentation broth. Agricultural residues contain large amounts of hemicellu

Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases that have a remitting, relapsing nature. During relapse, they are treated with drugs and surgery. The present study was based on individual data from patients diagnosed with CD or UC at Herlev University Hospital, Copenhagen, Denmark, during 1991 to 1993. The data were aggregated over calendar years; for each

Spectroscopic Photoemission and Low Energy Electron Microscopy (SPELEEM) is a very powerful and diverse microscopy technique for the investigation of surfaces, interfaces, buried layers and nanoscale objects like nanoparticles and nanowires. The many significant results from photoemission Electron microscopy (PEEM) in recent years are linked with the exploitation of advanced light sources such as

The conflict between the right to data protection and the right of access to documents is mirrored in the Regulations embodying these rights, as they appear to have conflicting end-goals. The two main conflicts are, first, between the Article 8 of Regulation 45/2001 and the Article 6(1) of Regulation 1049/2001, and second, between the Article 4(1)(b) of Regulation 45/2001 or the principle of purpo

Research question: What conditions promote or hinder business model innovation for sustainability in the field of upcycling and how do these conditions interact? Methodology: This single-case study is characterized by applying a qualitative research approach and an inductive reasoning with a systematic and transparent approach. The research conducted semi-structured interviews as the main source

There has long been a crisis of housing affordability in London, which the government and private sector are failing to address. On top of the socio-economic challenges brought about by this, London’s current and new stock of housing are not built to the necessary environmental standards to achieve legally binding environmental targets. However, the contentious Brexit vote and the continued uncert

In the near future, our species, and many others, face an upcoming shock in the global climate; one that could result in the potential extinction of more than just the human race. In order to combat this issue, the field of sustainability emerged throughout different sectors of society. One of the places that this topic has blossomed is within academia, and there are few things more important than

In this article I call for an awareness of the mobile commons– the informal support that exists among migrating people, NGOs, and activists – in relation to the realization of family reunification. Taking its point of departure in a concrete case of family reunification for young unaccompanied children, the article seeks to expose how the traditional legal notion of the liberal subject fails to pr

Research on the impacts of COVID-19 on mobility has focused primarily on the increased health vulnerabilities of involuntary migrant and displaced populations. But virtually all migration flows have been truncated and altered because of reduced economic and mobility opportunities of migrants. Here we use a well-established framework of migration decision-making, whereby individual decisions combin

In both the US and EU, policymakers and government agencies are acknowledging theimportance of having access to repair options, particularly for vulnerable product users who depend on their products. As such, repair can play an important role as a resource for resilience, but research is missing. We propose that repair can act as a resource for resilience. A comprehensive, structured way to unders

Although temporal conceptualizations of motivational processes have not held center stage in motivation science, the situation is currently changing. Drawing on work in the subfield of language learning motivation, where the motivational endurance needed to master a second language has been a major concern, the aim of this article is to contribute to the body of work currently exploring motivation

Longitudinal motion of the carotid arterial wall, as measured with ultrasound, has shown promise as an indicator of vascular health. The underlying mechanisms are however not fully understood. We have found, in in vivo studies, that blood pressure has a strong relation to the antegrade longitudinal displacement in early systole. Further, we have identified that a tapered geometry and the intramura

Recycling polymers by site-specific scission into short-chain oligomers/polymers, followed by recoupling these to form the original polymer presents an energetically more favorable shorter-loop chemical recycling in comparison to recycling into monomers. Here, we present the synthesis and polymerization of triaromatic diesters to prepare polyesters with acylhydrazone units as weak structural links

Older individuals with chronic atrial fibrillation (AF) often experience physical symptoms and feel psychologically unwell. In addition, these persons are prescribed lifelong medical treatment that requires regular monitoring. Through 11 individual interviews, this interpretive description study aimed to explore and describe lifelong medical treatment and the need for medical controls as experienc
