Popular Abstract in English Oil resources are finite; and political and economic factors affecting oil production,together with the environmental damage associated with the increased use of oil by a rapidly growing population, have underscored the need for developing cleaner technologies based on sustainable resources. In this context, any lignocellulosic biomass that is not used in the food chainThe present work was aimed at developing industrial S. cerevisiae strains with improved tolerance to two types of stressors encountered during the fermentation of lignocellulosic biomass that affect ethanol yield and productivity, namely hydrolysate-derived inhibitors and high temperature, and at understanding the response of yeast and mechanisms of adaptation to such stressors. In one part of the

Yrkesutbildningen i gymnasieskolan debatteras ständigt och det riktas ofta kritik mot den. Det är egentligen inte så konstigt, eftersom den ska uppfylla flera olika krav som inte alltid är så lätta att förena. Alla elever på ett yrkesprogram har möjlighet att uppnå grundläggande högskolebehörighet under gymnasieutbildningen, samtidigt som de ska vara väl förberedda för yrkeslivet. Utbildningen ska

The aim of this study, ”Botanical pictures for the public: On the publication of Carl Lindman’s Bilder ur Nordens flora”, is to investigate the process of how botanical illustrations are designed and produced and how they reach their readers. The perspective is that of book history. The study is based on a large body of previously unresearched empirical material consisting of originals, printed pi

Popular Abstract in Icelandic Landnám á jökulskerjum Plöntur hafa lengi verið taldar nauðsynlegar til að dýr geti numið land en þessi sýn er að breytast því rannsóknir hafa sýnt að smádýr nema oft land á undan plöntum. Landnám bæði plantna og dýra getur hafist um leið og nýtt land myndast en til að landnám takist þurfa nokkrir þættir að fara saman. Þau verða að komast á staðinn og þegar þangað erThe classical view of primary community assembly is that colonisation by plants is essential before invertebrates can establish. It has been recognised, however, that invertebrates can establish before plants, and that they may be important in the first steps of community assembly. Plant succession is well studied but assembly of invertebrates and how their dispersal abilities affect the community

Popular Abstract in Swedish Antikroppar är viktiga beståndsdelar av det naturliga immunförsvaret som skyddar oss mot smittämnen, såsom bakterier och virus. Utvecklingen av olika genetiska och biokemiska teknologier har dessutom möjliggjort användningen av antikroppar för en mängd ändmål, bl a för diagnostik och behandling av infektionssjukdomar och cancer. I denna avhandling, som bygger på fem vetAntibodies are key players of the immune system in higher vertebrates, which provide a defense against potentially lethal threats from the environment. Besides their importance in the immune defense, antibodies have a great potential as reagents in biological chemistry and diagnostics, and as therapeutic agents against both infectious diseases and cancer. Despite tremendous advances in all fields

Some European species of the genera Parmelia and Punctelia are analysed using molecular, morphological and chemical characters and notes on their distribution are presented. ITS sequences were compared from a total of 31 representative specimens. Parmelia ernstiae and P. serrana form a sister group to P. pinnatifida and P. saxatilis, whereas P. discordans and P. omphalodes are closely related and

The struggle for equality is fundamental to the reduction of poverty in Central America. Besides, one of the foremost goals of urban spatial planning, when implementing social policies, is to contribute to the reduction of poverty. This is done by producing a list of territorially-based actions and selecting those suitable for the implementation of social policies developed at national level. Howe
