I vår samtida tv-kultur, med kommersiella kanaler, kabel- och satellit-tv och inom en inte alltför avlägsen framtid också en digitaliserad sändningsform, har olika programformers verksamhet diskuterats och ibland även ifrågasatts. En av dessa programformer är utbildningsprogrammen där man menat att UR:s utbud ofta skiljer sig marginellt från SVT:s folkbildande program. Diskussionen om folkbildande

Indium arsenide nanowires are grown directly on silicon substrates (see figure and cover) using a method employing self-assembled organic coatings to create oxide-based growth templates. High-performance materials, such as InAs, could have great impact on future nanoelectronics if integrated with Si, but integration has so far been hard to realize with other methods.

The production of methane via anaerobic digestion of agricultural residues and industrial wastewater would benefit society by providing a clean fuel from renewable feedstocks. This would reduce the use of fossil-fuel-derived energy and reduce environmental impact, including global warming and pollution. Limitation of carbon dioxide and other emissions through emission regulations, carbon taxes, an

Soda lakes represent the most stable naturally-occurring alkaline environments on Earth and harbour a diverse population of alkaliphiles. Alkaliphilic microorganisms have attracted a great interest due to their ability to produce extracellular enzymes that are active and stable at high pH values. Screening for alkaliphilic starch-hydrolyzing bacteria from samples of soda lakes at the Ethiopian Rif

Popular Abstract in Swedish Enzymer har använts av människan sedan urminnes tider. Mycket tidigt lärde man sig att jäst kunde användas för att jäsa bröd och för framställning av vin och öl. Det är då just enzymerna som finns i jästsvampar som utnyttjas. I lite mera modern tid så fick enzymer ett stort användningsområde i tvättmedel på grund av deras unika förmåga att bryta ner fett och smuts vid gThe use of enzymes for synthetic applications is an area of increasing interest. Enzymes have been pointed out to be an environmentally friendly alternative to existing chemical methods, as well as making completely new synthetic routes possible. Over the last decades, much focus has been put on the enzyme group oxidoreductases, which can selectively introduce oxygen and hydrogen into molecules. T

This chapter illustrates the intimate connection between creativity and learning in music making and it is suggested that agentive learning across the individual and collective may be studied as expansive learning. By drawing on empirical data from instrumental vocal tuition and professional organ improvisation, it is discussed how individual experiences of tensions and problems in artistic work m

Popular Abstract in French L'inquiétude grandit quant à la perte de la biodiversité liée aux changements d'utilisation des terres, l’effet de cette perte sur les services écosystémiques fournis par les communautés naturelles et semi-naturelles et, finalement, la menace que cela pourrait entraîner sur le bien-être de l’Homme. Ce travail de thèse examine l'impact de l'utilisation des terres présenteConcerns are increasing about the loss of biodiversity under land use change and how this will affect the ecosystem services provided by natural and semi-natural communities and consequently how this will threaten human well-being. The thesis examines the impact of present and past land use on different aspects of biodiversity; namely species diversity, traits and functional diversity and on ecos
