Inorganic binders and dry mortars were stored in room climate and in a freezer over a four-year period. The rate of reaction and flow properties (only dry mortar) were tested to study the influence of storage time and storage temperature on the materials. Material properties were found to change in time and material stored at room temperature showed significantly higher changes than material store

This thesis deals with Chiral Perturbation Theory (ChPT), an effective field theory for the strong force used to describe meson interactions. The work done can be split in two parts. The first one is on ChPT in its standard formulation. This theory has been very successful so far in describing low energetic processes. However, it is still not entirely clear how much it can be trusted for precision

The process of selecting the right set of requirements for a product release is highly dependent on how well we succeed in prioritising the requirements candidates. There are different techniques available for requirements prioritisation, some more elaborate than others. In order to compare different techniques, a controlled experiment was conducted with the objective of understanding differences

Eight patients meeting Leonhard's criteria for cycloid psychosis were investigated on repeated occasions during a psychotic episode, with regional cerebral blood flow measurements and clinical ratings. The results showed that, at admission to the hospital, when the patients were clinically exacerbated, the mean hemispheric blood flow was significantly elevated compared with values from a normal co

Ten experienced teachers at LTH were interviewed about their experiences of teaching in English, as an example of internationalisation. All ten had previously been rewarded with (ETP) for scholarly teaching and they were all self-selected. The interviews focused on personal experiences in the form of narratives, both made by the interviewee personally, but also as narratives originating from other

Based on material from previous classes, three features were examined 1) the respective roles of student-to-student, teacher-to-student and student-to-teacher feedback, 2) the ways in which students collaborated with each other in a peer-learning mode, and 3) the strategies used to enhance the students’ extrinsic and intrinsic motivation. The purpose was to study and describe how feedback, peer le

Sustainable development rests on, among other things, the ability of policy to stimulate corporate actors to improve their environmental performance. Yet policy design and implementation is a challenging task in this area. This paper investigates this issue by examining the ability of the UK Emissions Trading Scheme to foster corporate sustainability from two perspectives: (a) its institutional fr

Popular Abstract in Swedish Sedan årtionden tillbaks finns en stor mängd klorerade organiska miljögifter spridda i vår miljö (t ex DDT, PCBer och dioxiner). Djur får i sig miljögifterna främst med födan och eftersom dessa ämnen som regel är svårnedbrytbara och inte kan omsättas i kroppen i någon större omfattning leder detta till att de istället lagras upp i djuren, framför allt i fettvävnaden. EtChlorinated fatty acids (ClFAs) are the major contributors of extractable, organically bound chlorine in fish lipids. A known anthropogenic source of ClFAs is chlorine bleached pulp production. Additional anthropogenic sources may exist, e.g., chlorine-containing discharge from industrial and house-hold waste and they may also occur naturally. ClFAs have a wide geographic distribution. They have,
