Turbines operating in wind farms are coupled by the wind flow. This coupling results in limited power production and increased fatigue loads on turbines operating in the wake of other turbines. To operate wind farms cost effectively, it is important to understand and address these effects. In this paper, we derive a stationary model for turbine interaction. The model has a simple intuitive structu
Objective: To describe the prevalence, baseline characteristics and factors associated with survival in out-of-hospital cardiac arrest (OHCA) with initial non-shockable rhythm sub-grouped into pulseless electrical activity (PEA) and asystole as presenting rhythm. Methods: The Swedish Registry of Cardiopulmonary Resuscitation is a prospectively recorded nationwide registry of modified Utstein param
The development of a plasmid-based genetic transformation protocol for Chlamydia trachomatis provides the basis for the detailed investigation of the function of the chlamydial plasmid and its individual genes or coding sequences (CDS). In this study we constructed a plasmid vector with CDS6 deleted (pCDS6KO) from the original Escherichia coli/C. trachomatis shuttle vector pGFP::SW2. pCDS6KO was t
Evaluated cross-section data files were prepared for stable tungsten isotopes with the objective to provide reliable and sound nuclear data for activation and inventory calculations of the European Spallation Source, which utilizes a tungsten target. The data files contain yields of radionuclides produced by proton induced reactions with incident energies up to 3 GeV. The calculations of cross-sec
A wealth of biospecimen samples are stored in modern globally distributed biobanks. Biomedical researchers worldwide need to be able to combine the available resources to improve the power of large-scale studies. A prerequisite for this effort is to be able to search and access phenotypic, clinical and other information about samples that are currently stored at biobanks in an integrated manner. H
The average consensus algorithm is a distributed procedure which allows a network of agents to agree on the average of a set of initial values. The computation occurs through local exchange of information only, namely the information exchange takes place only between agents which are neighbors with respect to a graph representing the system communication architecture. Several performance metrics h
The effect of water availability on stand-level productivity, transpiration, water use efficiency (WUE) and radiation use efficiency (RUE) is evaluated for different willow clones at stand level. The measurements were made during the growing season 2000 in a 3-year-old plantation in Scania, southernmost Sweden. Six willow clones were included in the study: L78183, SW Rapp, SW Jorunn, SW Jorr, SW T
In this paper we provide necessary and sufficient conditions for strongly group graded rings to be simple. For a strongly group graded ring R = circle plus(g is an element of G)R(g) the grading group G acts, in a natural way, as automorphisms of the comrnutant of the neutral component subring R(e) in R and of the center of R(e). We show that if R. is a strongly G-graded ring where R(e), is maximal
Immunomodulatory effects of various factor VIII and factor IX clotting factor concentrates (CFCs) and of albumin were evaluated by a sensitive assay measuring the incorporation of 3H-thymidine in phytohaemagglutinin-stimulated lymphocytes in the presence of monodansylthiacadaverine. In contrast to previous findings by others, we found lymphocyte transformation to be inhibited by all plasma-derived
It is proposed to capture localized plastic deformation via the inclusion of regularized displacement discontinuities at element boundaries (interfaces) of the finite element subdivision. The regularization is based on a kinematic assumption for an interface that resembles that which is pertinent to the classical shear band concept. As a by-product of the regularization, an intrinsic band width is
This is a Bachelor thesis on the subject of the food industry’s influence over the EU institutions. The purpose of the thesis is to find out how the great food companies affect the EU legislation on sugar regulation through lobbying. The thesis describes how the EU food- and health policies are shaped and how the lobbying works. The methodology used for the thesis is a qualitative content analysis
Despite the growing popularity of ginger beer, its production has been very little researched and poorly documented, the literature available regarding this topic being very limited. This thesis aims to fill this gap by exploring the final stages of development of a new alcoholic ginger beer, identify the difficulties encountered during production and evaluate various solutions to overcome them. I
There is an idea that nations form the basis of identity. Through history the rulers have tried to connect the cultural identity of the population with the identity the state is supporting, in order to further legitimize their ruling. This has constructed a conception of cultural homogeneity within a country, which in these modern years becomes more and more problematic with flows of migration. We
The purpose of this thesis is to examine the document “Hur kan det vara så här?” made by Swedish minority journalists on Sveriges television. The document was composed to shed light on how the journalists perceive the newsroom culture on the Swedish public service television company from their minority point of view. The question that the journalists raise is interesting, as SVT as the public serv

Popular Abstract in Swedish I detta doktorandprojekt har ett antal nya syntesmetoder utvecklats och studerats. En stor del av avhandlingen fokuserar kring införandet av en allylisk grupp i aromatiska föreningar. Allylaromatiska substanser är utmärkta startmaterial i syntesen av föreningar avsedda att användas som kontrastmedel för röntgen. Ett stort antal allylaromatiska substanser med varierande A new method for allylation of aromatic systems has been developed. A number of arylamines were converted via diazotization to the corresponding allylaromatic compounds using tert-butyl nitrite and an excess of allylic bromides with complete regioselectivity. Electron-withdrawing groups, in the aromatic moiety, were necessary to obtain good yields. The convenient experimental procedure allowed the
From all the wild berries that grow in Sweden only 2-5% is utilized (RISE, 2022). The United Nation has 17 goals for sustainable development, and many of those goals are related to sustainable food production (United Nations, 2022). A sustainable food product should have low environmental impact, social equity, and economic viability, while still containing essential nutrients (Woodhouse et al, 20
The aim of this study was to develop simple cellulose nanocomposites that can interfere with the quorum-sensing (QS)-regulated physiological process of bacteria, which will provide a sustainable and inexpensive solution to the serious challenges caused by bacterial infections in various products like food packaging or biomedical materials. Three cellulose nanocomposites with 1-5 w% octadecylamine-
The structural study of glycans and glycoconjugates is essential to assign their roles in homeostasis, health, and disease. Once dominated by nuclear magnetic resonance spectroscopy, mass spectrometric methods have become the preferred toolbox for the determination of glycan structures at high sensitivity. The patterns of such structures in different cellular states now allow us to interpret the s
Large-scale science research facilities, such as those for investigation into the smallest components of physical matter, often consist of buildings with quite extraordinary features as regards shape and scale. These architectures are semiotically interesting in several ways: they have extraordinary outer forms that reflect the their inner activities; they require forms of mediation and planning t
