The forest industry is one of Sweden’s most important business areas. As the use of paper is declining the need for this sector to find other alternatives is increasing. An attractive option to meet this demand is the establishment of forest biorefineries. However, economically suitable pretreatment methods for woody biomass, which minimize degradation of the structural carbohydrates and allow the
Hydrogels are a hydrophilic network of polymers (usually cross-linked polysaccharides) that are natural or synthetic. Applications of hydrogels are many in the biomedical field. Because of the high water absorption (10 to 200 grams of water per gram of hydrogel), hydrogels have a high degree of flexibility similar to natural human tissue. Human cells can be incorporated into the hydrogel, which in
Galactoglucomannans (GGM) can be used as a precursor for the production of surfactants, plastics, hydrogels etc. However, separation of galactoglucomannan (GGM) from lignin and lignin-carbohydrate-complexes using membrane filtration is difficult. Precipitation of GGM with anti-solvents is an approach that has been previously studied. A membrane filtration step prior to precipitation is economicall
We present a method to rapidly fabricate a large number of thermoplastic microfluidic systems where horizontal microchannels are separated by a porous membrane for modelling biological barriers. We optimize and combine solvent bonding, milling and laser cutting to fabricate in excess of 100 devices in two days. The optimized protocol relies on a commercial solvent blend, retention grooves for solv
We show that recent robust adaptive beamformers, based on reconstructing either the noise-plus-interference or the data covariance matrices, are sensitive to the noise-plus- interference structure and degrade in the typical case when interferer steering vector mismatch exists, often performing much worse than common diagonally loaded sample covariance matrix based approaches, even when signal-of-i
Humidified gas turbines (HGT) offer the attractive possibility of increasing plant efficiency without the cost of an additional steam turbine as is the case for a combined gas-steam cycle. In addition to efficiency gains, adding steam into the combustion process reduces NOx emissions. It increases the specific heat capacity (hence, lowering possible temperature peaks) and reduces the oxygen concen
This article examines the selection, marketing and reception of African fiction on the Swedish book market of the 1960s and 70s, through the series Afrika berättar, launched by Bo Cavefors Publishing, Ltd. Bo Cavefors was a Swedish publisher of writers such as Wole Soyinka, Ngũgĩ wa Thiong’o and José Luandino Vieira. The article discusses the way in which these literary works were received taking
The Swedish consumer magazine Råd & Rön (”Advice and Results”) has been available to Swedish consumers since 1958. For a major part of this time the Swedish state, represented by Konsumentverket (the Swedish Consumer Agency) and its predecessor, Konsumentinstitutet (the National Institute for Consumer Information), was the owner of the magazine. In 2006 Råd & Rön was sold to the independen
Undersökningens uppläggning Enkäter skickades i maj 2005 till dem som tagit läkarexamen i Lund 2001 och 2002. Frågorna berör både medicinsk och allmän akademisk kompetens. En uppföljningsenkät gick samtidigt till dem som tagit examen 1997 och 1998 och ingått i en tidigare alumnundersökning. Avsikten med uppföljningen är att ge en bild av hur arbetsuppgifterna förändras i den tidiga delen av läkark
The notion of animal welfare and of how to define it has been widely discussed within the literature. However, an integrative model, regarded to mirror the scope of animal welfare science and the ethical aspects of human treatment of animals directly related to the animals, has won some popularity the last 10-15 years. Thus the subjective experience of the animal, the health or fitness of the anim
