Phytase is an important enzyme in the food/feed industry. It catalyzes the hydrolysis of phytate, an anti-nutrient compound present in cereals and grains, to release orthophosphate and myo-inositol-6-phosphate with lower degrees of phosphorylation. Phytic acid is a strong chelator capable of complexing with a variety of metal ions under neutral and alkaline conditions, as well as with proteins and

A mathematical model is developed with the purpose of estimating the scale of permanent magnet materials consumption in hybrid and electric automotive traction systems. These estimations are compared to consumption figures from industries such as wind power, HVAC, consumer electronics and industrial machinery. The estimations generated are useful in strategic decision-making for production planning

The implementation of a physics-based model for non-linear least-squares analysis of proton-induced X-ray emission spectra via a Fortran programme REX is discussed. The modelling of distinct spectral components and of the physical effects involved is briefly discussed. Results are presented in graphical and tabular form. The limitations of the present model are discussed and future refinements ind

I tre fallrapporter från forskningsprojektet Framgångsrikt skolledarskap i olika skolkulturer presenteras resultat från omfattande empiriska undersökningar vid tre skolor. I rapporterna beskrivs och problematiseras skolornas respektive kultur: den aktuella gymnasieskolans kunskapskultur, där bildning kommit att bli ett kännetecken; den utvalda f-9-skolans karriärkultur, utsatt för ett kraftfullt f

A non-Gaussian time series with a generalized Laplace marginal distribution is used to model road topography. The model encompasses variability exhibited by a Gaussian AR(1) processwith randomly varying variance that follows a particular autoregressive model that features the gamma distribution as its marginal. A simple estimation method to fit the correlation coefficient of each of two autoregres

Innovation and industrial dynamics have grown in importance over the last 40-50 years as we have moved towards a more knowledge intensive society. In an effort to understand these developments in society new research fields have emerged such as innovation and entrepreneurship studies. In general, these two research fields are regarded as rather closely interlinked. In this study we elaborate on th
