2. 1. Streptococcal M protein and human C4BP

   Author : Jenny J Persson; Avdelningen för medicinsk mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infektioner; Infections; Medicin människa och djur ; Medicine human and vertebrates ; human C4BP; M protein; antigenic variation; sequence variability; Streptococcus pyogenes; innate immunity;

   Abstract : Antigenic variation of surface proteins allows microorganisms to evade the immune system of the infected host. This phenomenon represents an apparent paradox, because the variable protein must retain an important function, while its antigenic properties vary extensively. READ MORE

4. 2. Workplace Ethics : Some practical and foundational problems

   Author : Anders J Persson; Sven Ove Hansson; Matti Häyry; KTH; []
   Keywords : HUMANIORA; HUMANITIES; Philosophy; Ethics; contract of employment; ethics; ethical criteria; health and safety standards; Philosophy subjects; Filosofiämnen; Philosophy;

   Abstract : The aim of the present thesis is twofold: first, to analyse some practical ethical problems that stem from the workplace and the working environment and to offer guidelines concerning how such problems can be solved; second, to illuminate how the specific nature of work and the working environment is intimately connected to the relation between the employee and the employing entity, as set forth in an employment contract, and how the form and content of such contracts are, among other things, determined by culturally and socially established ideas. The normative question to be addressed is thus: which of these ideas should be maintained? This can be seen as a second-order, or more fundamental, ethical question whose answer depends on determining which normative principles are right. READ MORE

5. 3. Does education cause participation in politics?

   Author : Mikael J Persson; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Political science; Political participation;

   Abstract : In most studies of political behavior in Western countries, it is found that individuals with higher education participate to a greater extent in political activities than individuals with lower levels of education. According to the conventional view, education increases skills and knowledge but also affects political interest and political efficacy; factors that all in turn trigger political participation.

7. 5. District heating in future Europe : Modelling expansion potentials and mapping heat synergy regions

   Author : Urban Persson; Sven Werner; Lars J. Nilsson; Sweden Gothenburg Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; district heating; energy efficiency; distribution capital cost; heat demand density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation rate; effective width;

   Abstract : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.
