Complexes of oppositely charged polymers and surfactants (OCPS) in water come in many varieties, including liquid-crystalline materials, soluble complexes, structured nanoparticles, and water-insoluble surface layers. The range of available structures and properties increases even further with the addition of other amphiphilic substances that may enter, or even dissolve, the complexes, depending o
During the Younger Dryas cold event, the Scandinavian ice sheet readvanced in southwest Sweden and formed the Middle Swedish end-moraine zone (MSEMZ). Recent highway construction near Skara has created an exposure through the prominent ridge at Ledsjo. Through sketching and measurement of structural information, we have documented the internal character of the Ledsjo moraine. The moraine consists
A model for the adsorption of colloidal particles on a planar surface is analyzed by using a thermodynamic chemical equilibrium model and Monte Carlo simulations. Central to this investigation are that (i) particles and surface are considered to be of the same material and (ii) the particle-surface and particle-particle interactions are related using the Derjaguin approximation using a surface-sur
The rapid development of handheld technologies such as smartphones and personal digital assistants in recent years has created opportunities for the mobile workforce to take advantage of computerised information systems. To apprehend and harness the opportunities of computerised information systems implemented on handheld devices it is crucial to fully understand the user group and the handheld te
The Baltic Sea Region is rapidly becoming one of the world’s more competitive regions. The region is capitalising on its strengths and making the most of its diversity to stimulate innovation, build a strong pool of skilled labour and foster entrepreneurship. A deep spirit of co-operation and integration has led the Baltic Sea countries to set up ambitious governance frameworks to pursue economic
The purpose is to present a theoretical model of the concept employeeship. Employeeship concerns all employees and covers the vertical perspective of work behaviors and relationships between formal leaders and followers, and the horizontal perspective between co-workers on all organizational levels. This enables the study of both formal and informal leadership, authentically recognizing that all e
The main purpose of this dissertation is to describe how terminally ill patients experienced their situation, and what their views about the future were. Further, the experiences and attitudes of relatives of such patients, and of health care professionals, were also central. Focus was on existential issues, such as autonomy, meaning, guilt, relations, dignity, and communication. In the first pape
Popular Abstract in Swedish Många av alla kemiska processer som pågår i våra kroppar utförs av proteiner. När de inte fungerar blir vi sjuka. I vissa fall, till exempel vid Alzheimers sjukdom eller Creutzfeld Jacobs sjukdom, beror det på att ett visst protein har fel form. Att förstå hur proteiner antar sin slutliga form och vad det har för inverkan på proteinets funktion är således viktigt. ÅVery little is known about a considerable part of all proteins and it is time consuming and expensive to study each individual protein to determine its function, structure and cellular role. Proteins retain structural, functional and sequential characteristics from ancestral proteins and hence two proteins that share a common ancestor, i.e. are homologs, will to some extent have similar sequen
Replacing fossil fuels by bio-fuels has many advantages, such as the reduction of CO2-emission to the atmosphere, the possibility for non-oil-producing countries to be self-sufficient in fuel, and increased local job opportunities. Bio-ethanol is such a promising renewable fuel. However, today it is produced from sugar or starch-raw materials that are relatively expensive. To lower the production
Severe combined immunodeficiency (SCID) comprises a heterogeneous group of primary immunodeficiencies, a proportion of which are due to mutations in either of the 2 recombination activating genes (RAG)-1 and -2, which mediate the process of V(D)J recombination leading to the assembly of antigen receptor genes. It is reported here that the clinical and immunologic phenotypes of patients bearing mut
Purpose: To study the feasibility of using transscleral visible/near-infrared spectroscopy (Vis/NIRS) to estimate the content of haemoglobin in choroidal tumour phantoms of ex vivo porcine eyes. Methods: Thirty enucleated porcine eyes were prepared with a tumour phantom made by injecting a suspension of gelatine, titanium dioxide and human blood into the suprachoroidal space. The blood concentrati
Recent studies have demonstrated that the combination of x-ray tomography during triaxial tests (”in-situ” tests) and 3D- volumetric Digital Image Correlation (3D-DIC) can provide important insight into the mechanical behaviour and deformation processes of granular materials such as sand. The application of these tools to investigate the mechanisms of failure in rocks is also of obvious interest.
REDD is one of the latest additions to a series of incentive-based mechanisms for reducing carbon emissions. Although international negotiations have not eliminated uncertainties regarding its social, economic and political implications, many developing and emerging countries have begun to engage in REDD. Peru, the country with the world’s fourth largest tropical forest area has good reason to par
In recent years, we have witnessed an intensive scholarly discussion about the limitations of traditional inward looking regional innovation strategies. New policy approaches put more emphasis on promoting the external connectedness of regions. However, the institutional preconditions for collaboration across borders have received little attention so far. The aim of this paper is to investigate bo

BACKGROUND AND PURPOSE: MR imaging has made it easier to distinguish among the different types of intracranial mass lesions. Nevertheless, it is sometimes impossible to base a diagnosis solely on clinical and neuroradiologic findings, and, in these cases, biopsy must be performed. The purpose of this study was to evaluate the hypothesis that proton MR spectroscopy is able to improve preoperative d
