Popular Abstract in English Extraction of valuable substances from plants using a solvent has been practised in many fields. One of the examples is making coffee or tea using hot water. In agricultural and food industry, there are tons of wastes containing valuable compounds that can be extracted before they go to incineration. Extractions are usually performed in organic solvents such as methanolPressurised hot water is an environmentally friendly alternative to hazardous organic solvents such as methanol and heptane. One of the many applications of using pressurised hot water extraction (PHWE) is to extract polyphenols from plants. The challenges in PHWE lies with the optimisation of extraction yield. One factor that is often overlooked is the risk of degradation of thermally labile comp

Popular Abstract in Swedish Under 1900-talet har jordbruket förändrats drastiskt. Från ett småskaliga lantbruk där åkrar, ängar och betesmarker avlöste varandra, och varje gård var beroende av att både odla mat och hålla djuren med foder, till ett allt mer specialiserat jordbruk där både de enskilda gårdarna och hela regioner specialiserat sig mot antingen spannmålsproduktion eller djurhållning. OAs a consequence of agricultural intensification, large areas of non-crop habitat have been lost and farmland biodiversity has declined. Previous studies have shown that the extent of non-crop habitat influences farmland biodiversity, but the relative importance of different habitat types is less well known and the contribution of small incidental habitats to landscape-scale species richness is no

Abstract in UndeterminedAssessments of students’ knowledge and skills are sometimes habitually performed, but the design of proper assessment concepts – beneficial to both teaching and learning – ought to be a central issue for all course planners in higher education. The main purpose of this paper is to discuss a variety of assessment elements, as well as ways in which to combine them. It uses ex

Popular Abstract in Swedish Denna avhandling belyser reformer och åtgärder inom högskolesektorn (policies of higher education) som genomfördes av socialdemokratiska regeringar i Sverige och Tyskland, här speciellt i Nordrhein-Westfalen, från mitten av 1960-talet till och med år 2000. Utgångspunkten för avhandlingen var den omfattande litteraturen om förändringar inom europeiska högskolesystem. DetHigher education has become a mega-topic in both political and scientific debate. Developments in systems of higher education and changes in the governance of such systems have been discussed in the literature. Such changes are brought about by collective actors within institutional settings. The present volume considers the policies of higher education supported by Social Democratic governments i

This paper provides three short and very simple proofs of the classical Gibbard-Satterthwaite theorem. The theorem is first proved in the case with only two individuals in the economy. The many individual case follows then from an induction argument (over the number of individuals). The proof of the theorem is further simplified when the voting rule is assumed to be neutral

Vi har studerat hur omfattningen av den kursansvariga lärarens behörighetsgivande pedagogikutbildning (BHU) samvarierar med studenternas bedömningar av den pedagogiska kvalitén på kurser uttryckt genom kursutvärderingarnas data från Course Experience Questionnaire (CEQ). Vi har även studerat hur CEQ-resultaten ser ut beroende på ifall den kursansvariga läraren har graden Excellent Teaching Practit
