The protein folding problem is addressed focussing on the hydro- phobicity patterns in the amino acid sequences and structures. Both real and model proteins are investigated. The hydrophobicity pattern of real proteins is probed in two ways. First, it is asked which binary pattern is most conserved within groups of related proteins. Not unexpectedly, the most conserved patterns are strongly corre
By tradition, comparisons between first and second language acquisition involve data from child or adult L2 learners and data from young L1 children. However, there is a subgroup of L1 children, namely children with Specific Language Impairment (SLI), which is rarely accounted for in these comparisons. These are children with significant problems in acquiring their mother tongue despite growing up
Popular Abstract in Swedish Sammanfattning Nukleotider påverkar kärltensionen och hjärtats slagkraft. Då ett blodkärl skadas, då blod koagulerar eller vid minskad syretillförsel till hjärtat frisätts en mängd ämnen från kärlväggar och blodceller. Bland annat frisätts så kallade nukleotider (ATP, ADP, UTP och UDP). Nukleotider har tidigare visats ha viktiga funktioner inuti cellen vid energiomsättnThe aim of the thesis was to examine the expression and function of the extracellular nucleotide P2 receptors in the cardiovascular system. In the cardiovascular system nucleotides are released during shear stress, hypoxia, ischemia, from endothelial cells, smooth muscle cells, aggregating platelets, inflammatory cells and erythrocytes. We demonstrate that ATP, ADP, UTP and UDP induce vascular rel
The use of systems analysis involving tools like Causal loop diagrams and stock and flow diagrams can be shown in practical tests to greatly enhance systems insight and understanding of the dynamic behaviour of complex systems. Whereas many students may have difficulty understanding what a coupled system of differential equations really do, systems analysis creates such insights even to those with
Many modern office buildings have highly glazed facades. Their energy efficiency and indoor climate is, however, being questioned. Therefore more and more of these buildings are being built with double skin facades, which can provide: a thermal buffer zone, energy savings, wind protection with open windows, fire protection, aesthetics, solar preheating of ventilation air, sound protection, polluta

This thesis comprises ecological, morphological and physiological studies of the carrot psyllid Trioza apicalis (Homoptera: Psylloidea) with particular focus on olfaction. Data from inventories of winter habitats suggest that T. apicalis prefer Picea abies over Pinus sylvestris and Juniperus communis as winter hosts. Their migration range is at least I km, and we found no clear wind-borne pattern
The focal company in this study is establishing a partnership style of’ relationships with a few selected suppliers. The article focuses on the driving forces behind such an initiative. It attempts to answer the questions why this company is trying to develop a closer working relationship with one of the selected suppliers, the supplier of corrugated board. The purpose of the article is thus to an
A series of previous papers develops a dipole model in initial state impact parameter space that includes subleading effects such as running alpha strong, unitarity, confinement and saturation. Here some recent work is presented, where the model is applied to a new set of data: vector meson production in photon-proton, DVCS and t-dependence in elastic proton-proton collisions. This allows us to tu
