Abstract. Intended as food for thought this revue offers a general orientation on Alzheimer’s disease (AD) with comments on the brain changes and clinical features. But more importantly, it points out recent research findings which may offer new alleys for AD research pertinent to the etiology and pathogenesis of AD and alternatives to the so far rather unfruitful and costly amyloid research trail

The problem of integrating the Camassa-Holm equation leads to the scattering and inverse scattering problem for the Sturm-Liouville equation -u '' + 1/4 u = lambda wu, where w is a weight function which may change sign but where the left-hand side gives rise to a positive quadratic form so that one is led to a left-definite spectral problem. In this paper the spectral theory and a generalized Four

Anti-idiotypic antibodies (anti-Id) to autoantibodies are present in several autoimmune diseases and are hypothesized to have regulatory function. Recently we reported the presence of anti-Id to a major type 1 diabetes-associated autoantibody (CAD65Ab) in sera of healthy individuals. Our current assay for the detection of GAD65Ab-specific anti-Id requires the initial removal of anti-Id from the se

A novel technique to identify and split clusters created by multiple charged particles in the ATLAS pixel detector using a set of artificial neural networks is presented. Such merged clusters are a common feature of tracks originating from highly energetic objects, such as jets. Neural networks are trained using Monte Carlo samples produced with a detailed detector simulation. This technique repla

Highly skilled workers are increasingly recognised as a key competitive asset for regional development, and claims have been made that emphasise the importance of certain amenities for the prospects of attracting this particular group of workers. We use a recent large-scale survey to investigate the relative importance of jobs versus amenities for the decision to migrate, as perceived by the migra

Popular Abstract in Swedish Teamarbete är en populär arbetsform inom hälso- och sjukvården och teamarbete anses kunna göra sjukvården både effektivare och säkrare. Detta gäller inte minst för arbete med kirurgi på operationssal. På operationssalen möts narkosläkare, narkossjuksköterskor, kirurger, operationssjuksköterskor och undersköterskor i olika konstellationer för att tillsammans behandla patThe topic of this thesis is teamwork in healthcare. Healthcare is often described as complex. This description is more appropriate now than ever with the extensive specialization that has taken place in recent decades resulting in increasingly specialized physicians and nurses. While this specialization has made it possible to cure even sicker patients, it has also resulted in less overlapping kno

Asteroseismology has the capability of precisely determining stellar properties that would otherwise be inaccessible, such as radii, masses, and thus ages of stars. When coupling this information with classical determinations of stellar parameters, such as metallicities, effective temperatures, and angular diameters, powerful new diagnostics for Galactic studies can be obtained. The ongoing Stromg

Oil/water emulsions can be produced through phase inversion, by adding water to a reverse water/oil microemulsion. According to small angle neutron scattering experiments and visual observations performed during phase inversion, the stages of this process are as follows: (i) upon water addition, the microemulsion gives way to a highly swollen lamellar phase; (ii) the transient lamellar phase break

This paper examines the increasing use of bilateral investment treaties as instruments of foreign investment protection. The outcomes of treaty arbitrations are analysed to assess the extent to which treaties limit the economic policy choices available to host states. The disputes are also analysed to determine how such treaties may affect the development of legal institutions and the general appl

The aim of this study is two folded. We wish to investigate if there is a value premium from hedging jet fuel exposure for American and European airlines. We also seek to answer if airlines can affect their probability to default by using Risk Management. During the period 2003 – 2006 there existed a value premium for airlines that hedged their expected future consumption of jet fuel. This premium

Whether executed as full-scale war or acts short of war, acts of aggression have consistently shaped the history of humankind. Acts of aggression would not occur if it were not for the involvement of individuals. The historical development of aggression in international law has seen a shift from a regime solely focusing on the unlawfulness of the action by States, to include the unlawfulness of th

Public participation in environmental decision-making has been increasingly recognised in national, regional and international law in the last decades. In parallel, the World Bank - an inter-state development bank and international organisation - has developed a set of safeguard policies including provisions on public participation in environmental decision-making. Public participation is about re

This paper develops a theoretical approach towards understanding treaty opt-outs from EU common policies by drawing on Putnam’s Two-Level Games theory. In doing so, the paper first presents treaty opt-outs as defections from negotiations by looking at previous research regarding opt-outs. Then, the paper goes on to concentrate on different European integration theories in order to explain their sh

Thesis Purpose: This thesis investigates users of crowdfunding platforms in order to further the insight into understanding what affects their motives and behaviour. The relationship between intrinsic and extrinsic motivation as well as peer influence is investigated. Theoretical Perspective: This study is grounded on the limited theories surrounding crowdfunding and crowdsourcing, as well as rele

This thesis is about the licensing system of the Creative Commons discussed from the perspective of the theory of the commons mostly as formulated by Elinor Ostrom. The work is started by describing the concepts and theory of common pool resources and regime of the commons for production and distribution of these resources. The main characteristics for successful traditional commons – efficiency,

Living with dementia means struggling to preserve a sense of self, to retain (and reevaluate) one's values in a new situation, and to search for a new way of life. This study explored the meaning of everyday life as expressed by 11 people suffering from dementia. Data were collected through interviews with people in the early stage of a diagnosed dementia disease. The findings indicate that many p

Two different self-adjoint Pauli extensions describing a spin-1/2 two-dimensional quantum system with singular magnetic field are studied. An Aharonov-Casher type formula is proved for the maximal Pauli extension and the possibility of approximation of the two different self-adjoint extensions by operators with regular magnetic fields is investigated.
