In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. Nevertheless, high production costs associated with traditional PHA production based on fermentation by pure microbial cultures have so f

Det här föredraget rapporterar resultat från ett postdoc-projekt som undersökte värdet av översättning från modersmålet (L1: svenska) till målspråket (L2: engelska) för utvecklingen av språkfärdigheten hos studenter som läste engelska på universitetets A-nivå. Med språkfärdighet menas här studenters förmåga att på ett korrekt sätt använda vissa grammatiska strukturer i L2 som visat sig särskilt pr

Popular Abstract in English Alcohols and aldehydes are used in the chemical industry largely as a starting material for the manufacture of a wide range of products. They are also used as such in various industrial applications. The flexibility is due mainly to the functionalities of the alcohols and aldehydes being hydroxylic and carbonylic, respectively. Much interest is directed nowadays at convNowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. Two different processes have been studied in the present work: the selective oxidation of methan

Jag får ofta frågan om den här övervakningshysterin som diskuterats högt och ljudligt senaste tiden faktiskt berör gemene man. Det är en bra fråga. Svaret är att det är oklart. Hela övervakningsfrågan är en balansgång mellan sådant som effektivitet i brottsbekämpning och allas vår personliga integritet.

This paper stems from an inductive research problem: the support given to the military-deep state by the youth revolutionary movement in Egypt’s political upheavals of summer 2013. Why would the youth revolutionary movement choose to support the military-deep state’s political maneuverings, and what is the precise nature of this support? To answer these questions, this paper chooses to explore two

The working life of today is characterized by a changing environment with heavier workload, lack of control, temporary work contracts and decreased workplace support. In recent years there has been a growing interest in studying the impact of insecure employment and several studies show that organizational changes and downsizing have negative consequences for the employees. Some authors argue that
