Popular Abstract in Swedish Människan har under mycket lång tid använt enzymer vid tillverkning av livsmedel, bland annat vid syrning av mjölk, jäsning av bröd och bryggning av öl och vin. Man använde sig då av hela levande organismer och först på slutet av 1800-talet kunde den aktiva substansen isoleras. Dessa aktiva substanser fick samlingsnamnet enzym, vilket kommer från grekiska och betyder "iThe influence of different reaction parameters on enzyme selectivity was investigated. The reaction conditions studied were solvent dependence, water activity and reaction temperature. The improved selectivity was observed as higher synthetic yields in a-chymotrypsin and subtilisin catalyzed peptide synthesis respectively, and as higher enantioselectivity in the asymmetric reduction of ketones cat

Innovative value creation models (IVMs) that take into consideration environmental costs and social goals in addition to financial profit in which new modes of production, consumption and value creation are devised by new set of act

Popular Abstract in Swedish Vitamin A är nödvändigt för kroppen. Det behövs för synen och för normal utveckling av foster och celler. Vitamin A krävs t. ex. också för optimalt immunförsvar och för fortplantningen. Ett stort globalt problem är vitamin A-brist i tredje världen, framför allt hos barn och gravida. Vitamin A-brist hos dessa grupper ger upphov till bl. a. blindhet och ökad dödlighet i The aims of these studies were to evaluate retinoid measurements, more specifically the performance of all-trans and 13-cis retinoic acids methods in clinical experimental settings and to evaluate the informational value of these measurements in relation to S-Retinol. Biological and analytical variations for retinoids were evaluated for healthy subjects. The performance of the retinoic acid measur

Incineration of municipal solid waste (MSW) has resulted in large quantities of residues which can be recycled in roads and landfill covers provided the environmental concerns related to leaching of salts and metals can be mitigated. The pollutant transport from these residues depends on quantity and variability of moisture at re-use sites. For realistic assessment of leaching rates and pollutant

Many popular direction-of-arrival (DOA) estimators rely on the fact that the array response vector of the array is Vandermonde, for example, that of a uniform linear array (ULA). Array interpolation is a preprocessing technique to transform the array response vector of a planar array of arbitrary geometry to that of a ULA over an angular sector. While good approximation within the target sector is
