Full-scale ethanol production from spruce has been evaluated, mainly from an energy perspective, using an Aspen Plus-model including all major process steps. The model input was based on data recently obtained on lab scale or in a process development unit. A number of different process configurations are presented in order to demonstrate how heat integration within the ethanol process significantl

Although Moral Foundations Theory claims that the foundations of morality are universal, there are still few studies addressing it through non-English measures. In the current research, 540 persons filled out a Swedish translation of the Moral Foundations Questionnaire, and 332 of them filled out political attitude measures. Confirmatory factor analyses suggested that the fit of the five-factor mo

Popular Abstract in Swedish Populärvetenskaplig sammanfattning: Det genomgående temat i avhandlingen är hur handeln mellan den Europeiska Unionen (EU) och utvecklingsländer kan öka. Två olika policyalternativ utvärderas: så kallade handelspreferenser samt förenklingar av handelsprocedurer. Handelspreferenser innebär i sin enklaste form att höginkomstländer kräver lägre tullar på importvaror somThe main theme of the thesis is how to increase trade between the European Union (EU) and developing countries. Two available policy options are assessed: trade preferences and trade facilitation. Chapter 1 offers a broad discussion of these policies, and concludes that while trade preferences, which once dominated North-South trade relations, are at a risk of becoming obsolete, trade facilitation

During recent decades we have witnessed growing scientific concern, public debate and media attention concerning the possible adverse effects on humans and wildlife that may result from exposure to a wide range of environmental contaminants. These contaminants are called endocrine disrupters, or endocrine-disrupting compounds (EDCs) and are defined as chemicals that interfere with the function of

Abstract in UndeterminedThe use of a polar diagram method for describing and evaluating the machinability ofInconel 718 was explored. Five key parameters of the work material, representing themechanical and physical properties, which have the strongest influence on its machinability,were employed in the diagrams. These five parameters were integrated into asingle polar diagram, used to describe th

A pilot-plant study, made to clarify whether biological denitrification is a possible and suitable method for nitrate reduction of drinking water in Sweden is presented. The concentration of nitrate-nitrogen in un-treated water was 10–15 mg/l. The reactor was a 1.2 m aluminium tube with a inner diameter of 0.19 m. 0.75 m was filled with Filtralite®, expanded clay, through which the nitrate-contami

Purpose: To describe the clinical phenotype of the complete type of X-linked congenital stationary night blindness (CSNB1) with different types of mutations in the NYX gene. Methods: The clinical and genetic data from 18 male patients with eight different mutations from two ophthalmological institutes were reviewed. The variability in refractive error, reduced visual acuity and full-field electror

In this article the authors reflect upon and critically examine signs of a contradiction in higher education which they discuss in terms of the tension between 'use value' and 'exchange value'. Use value here represents learning as something valuable ‘in itself’ whereas exchange value represents learning as an achievement of grades and credits to be ‘traded’ on a market. Their aim in this article

The self-diffusion coefficients of water in casein solutions and gels were measured using a pulsed-gradient spin-echo nuclear magnetic resonance technique (PGSE NMR). The dependence of the self-diffusion coefficient of water on the concentration and structure-of casein is reported. The results were analyzed using a cell model. It was found that the water self-diffusion coefficient is insensitive t
