We use one-loop Heavy Meson Chiral Perturbation Theory (HMChPT) as well as a relativistic formulation to calculate the chiral logarithms m(pi)(2) log (m(pi)(2)/mu(2)) contributing to the formfactors of the semileptonic B -> pi decays at momentum transfer q(2) away from q(max)(2) = (m(B) - m(pi))(2). We give arguments why this chiral behaviour is reliable even in the energy regime with hard or fast
Through the integrated framework of participation theory and political economy, this article analyzes participatory opportunities in the virtual world Habbo Hotel, and how participation is constrained and framed by the producer’s commercial strategies, which are based on advertising and sales of virtual goods. The study also looks into the ways in which the producer Sulake Corporation discursively
The interactions of the ECM (extracellular matrix) protein asporin with ECM components have previously not been investigated. Here, we show that asporin binds collagen type I. This binding is inhibited by recombinant asporin fragment LRR (leucine-rich repeat) 10-12 and by full-length decorin, but not by biglycan. We demonstrate that the polyaspartate domain binds calcium and regulates hydroxyapati
In order to understand ritual in the past, archaeology has long relied on theories developed in other disciplines. While these theories, which often rely on written or oral information, have added many important dimensions to our interpretation of the archaeological record, they have often proven difficult to successfully articulate with the archaeological sources. Moreover, archaeology has tended
We present a framework based on object orientation with novel principles for how to store, analyze and integrate electrophysiological data. These principles are: (I) Using a Decorator pattern for storing analysis data in an object model, (II) using a Core Classes data structure for integration through mediation in a service bus architecture, and (III) choosing the single unit as the finest structu
The world continues to be shaped by crises in both new and familiar forms. International and non-international armed conflicts and disasters are barriers to individual wellbeing, development, stability, and in the case of the former, represent a basic challenge to peace. The aftermath of such crises, in which communities can be rebuilt and the fabric of society can be mended, can be a time for rec
Poly-3-D-hydroxybutyrate (PHB) is a biopolymer naturally produced by a range of bacterial species. PHB production both from glucose and xylose has also been enabled by engineering the robust baker’s yeast Saccharomyces cerevisiae, however yields remain low. In the present study, additional modifications were carried out in S. cerevisiae strains already expressing functional enzymatic pathways for
G protein-coupled receptor 30 (GPR30) is a ubiquitously expressed receptor reported to bind and become activated by estrogen (17β-estradiol). However, the role of GPR30 as an estrogen receptor for rapid estrogenic signaling is not completely accepted, and controversies exist regarding the identity of the cognate ligand, signaling, and subcellular localization of the receptor. Expression of GPR30 i
In this thesis the heating area of a belt furnace for annealing metal powder has been modeled. The model was extended with PI-controllers for controlling the energy added to the model. It was simulated with differently tuned controllers to test tuning principles for finding suitable control parameters for the process. The most promising tuning principles was then written as a manual with the aim f
Since the introduction of Edison’s lightbulb over one-hundred years ago, humanity has struggled to keep up with electrification for all. With global attention now aimed at sustainable energy production, the struggle becomes more complex by not only obliging energy access, but access to clean energy. The concept of microgrids has been promising for filling in the demand, but not quickly enough to m
Neonicotinoid insecticides are agonists to nicotinic acetylcholine receptors (nAChRs) in the brains of insects. At sub-lethal doses these chemicals cause behavioral abnormalities in several bee species, reducing overall fitness. nAChRs expressed in the optic lobes of insects bind neonicotinoids, thus may be involved in these behavioral changes. Here we attempted without success to visualize the pr
Tolkning och kvantifiering av strålningseffekter pga. atmosfäriska partiklar är en signifikant del av IPCC’s modellering av hur tidigare klimat förändrats och hur förändringar i framtiden kommer se ut. I den här studien vill vi strukturera och analysera observationer av huvudsakligen svavelpartiklar positionerade i stratosfären från naturliga och möjligtvis mänskliga källor, med hänvisning till va
Ethiopia is the second most populated country on the continent of Africa, with a high density of young people. Its economy remains largely based on agriculture, however, in recent years, slow structural change can be seen. Concurrently, youth education has been on the rise. Due to this phenomenon, the educated youth are now trying to match their skills with current employment opportunities. As a c
For efficient treatment of many diseases of the lung, it is beneficial to deliver the medicine to the respiratory tract directly. This ensures a rapid response since it can enter the bloodstream directly through the alveolar epithelium. Consequently, also decreases systemic effects due to the local treatment. Dry powder inhaler (DPI) is today one of the most used inhalers for pulmonary delivery.
In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a

The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. The PSTs have historically been designed based on hydraulic
