Popular Abstract in Swedish Joniserande strålning- en introduktion (Ionizing radiation- Introduction in Swedish) 13.1 Storheter och enheter Effekten av strålningen från ett radioaktivt ämne eller röntgenapparat kallas stråldosen, eller egentligen den effektiva dosen , och anges i enheten sievert (Sv). Aktiviteten av ett radioaktivt ämne anges i enheten becquerel (Bq) och anger antal sönderfallanIn this thesis quantitative analyses of radionuclide concentrations in bioenergy fuels such as peat, wood chips and straw are presented. For comparison a brief description is included of radionuclide concentrations and radiation doses from other sources of power and also from some industrial applications. Radiation is a natural phenomenon and radionuclides occur naturally. The first man-made spre

The paper gives an account of the concept of 'hapiness' and 'felicity' in the discourse of 18th century thought.

In Botswana accessing water resources and controlling the use of water sources is imperative for agricultural production. Development of water sources

Popular Abstract in Swedish Den här avhandlingen handlar om hur moln påverkas av luftburna partiklar, så kallade aerosolpartiklar. Moln bildas i atmosfären när vatten övergår från gasfas till vätskefas, det vill säga när vattenånga kondenserar. För att molndroppar ska kunna bildas krävs dock aerosolpartiklar, som vattenångan kan kondensera på. Antalet partiklar i luften kan därigenom påverka hur mCloud droplets never form in the atmosphere without a seed in the form of an aerosol particle. Changes in number concentrations of aerosol particles in the atmosphere can therefore affect the number of droplets in a cloud. Higher concentrations of aerosol particles in the atmosphere lead to clouds with more droplets and if the amount of liquid water in the clouds stay the same, the droplets become

This article focuses on sustainability and environmental challenges in spa industry and describes motivations and possible barriers spas can face while addressing them. Environmental issues are gaining on importance for spa industry, as visiting spa becomes a popular leisure activity, leading to steady growth of the industry and increased public visibility.
