Effects of Past and Current Land Use on Biodiversity: from a semi-natural grassland on Öland (Sweden) to a European perspective

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

Aromatic Allylation via Diazotization; Application in synthesis of heterocyclic compounds

A new method for allylation of aromatic systems has been developed. A number of arylamines were converted via diazotization to the corresponding allylaromatic compounds using tert-butyl nitrite and an excess of allylic bromides with complete regioselectivity. Electron-withdrawing groups, in the aromatic moiety, were necessary to obtain good yields. The convenient experimental procedure allowed the

The Rhythm of the Unit Is the Pace of Life: A Study of Everyday Activities and Sleep in Swedish Residential Care

Social and physical activities can improve sleep in older people. However, living in a residential care facility has been associated with a limited potential for activities and increased inactivity, reflected in poor sleep among residents. In turn, poor sleep can impair physical and mental functions. This paper explores sleep habits and everyday activities at three residential care facilities and

Transportation fuels from Swedish biomass - environmental and cost aspects

In this paper, technical and economic prerequisites to attain reduced carbon dioxide (CO2) emissions through the use of biomass-based energy carriers in the transportation sector are studied. CO2 emission reduction per unit of land used for biomass production as well as costs for CO2 emission reduction are estimated when substituting rape methyl ester, biogas from lucerne, ethanol from wheat and e
