Description of the paper – e.g. topic, research question, objective, purpose, value, conceptual or theoretical framework, state of the art: Adult learning is a subject of ever growing interest, as the population of persons 65 and older grows in industrialised countries. By 2010 the number of retired persons in the European Union will be almost twice as large as in 1995 (Ilmarinen & Costa, 2000

Au nanoparticles are commonly used as seeds for epitaxial growth of III-V semiconductor nanowires. However, the interaction between Au and In-containing III-V materials makes it difficult to control the growth of more complex nanowire structures in materials such as InAs. Here we report the growth of InAs nanowires and branched nanotrees using Au and Au-In nanoparticles. We show that the initial c

The purpose of this study was to evaluate the effects of hepatic vein occlusion by stent-graft used in transjugular intrahepatic portosystemic shunt (TIPS). The experiments were performed in six healthy pigs under general anesthesia. Following percutaneous transhepatic implantation of a port-a-cath in the right hepatic vein, TIPS was created with a stent-graft (Viatorr; W L Gore, Flagstaff, AZ, US

More than 235 million patients undergo surgery every year worldwide, but less than 1% are enrolled in surgical clinical trials-few of which are international collaborations. Several levels of action are needed to improve this situation. International research collaborations in surgery between developed and developing countries could encourage capacity building and quality improvement, and mutually

We performed high-resolution simulations of two stellar collisions relevant for stars in globular clusters. We considered one head-on collision and one off-axis collision between two 0.6-Msolar main-sequence stars. We show that a resolution of about 100000 particles is sufficient for most studies of the structure and evolution of blue stragglers. We demonstrate conclusively that collision products

Pre-treatment of sludge before anaerobic digestion can increase methane production and degradation of organic matter. There are various pre-treatment methods for this purpose. Anaerobic digestion tests were performed for comparison of three pre-treatment methods (hygienisation, ultrasonic treatment and enzyme dosing) used separately or in combination on biosludge and mixed sludge. COD solubilisati

Popular Abstract in Swedish Avhandlingen är baserad på forskning rörande sambandet mellan omvändelsemotiv och Kristusbild bland unga konvertiter i Brazzaville, Republiken Kongo. Förf. visar att samband föreligger och att de vanligaste Kristusföreställningarna kan relateras till två arketyper i kongolesiska traditionella trosföreställningar: nämligen broder-anfadern (Yaya) och häxdoktorn (nganga).

Cellular neural networks are widely used with real-time image processing's applications. Such systems can be efficiently realized using macro enriched field-programmable gate-arrays. This paper explores the benefits of packet switching and discusses its advantages over a current design based on circuit switching. The implementation is performed using Xilinx Virtex-II Pro P30 and handles around 500

Individualists hold that moral responsibility can be ascribed to single human beings only. An important collectivist objection is that individualism is morally deficient because it leaves a normative residue. Without attributing responsibility to collectives there remains a “deficit in the accounting books” (Pettit). This collectivist strategy often uses judgment aggregation paradoxes to show that

This paper asks whether persistence can be a matter of convention. It argues that in a rather unexciting de dicto sense persistence is indeed a matter of convention, but it rejects the notion that persistence can be a matter of convention in a more substantial de re sense. However, scenarios can be imagined that appear to involve conventional persistence of the latter kind. Since there are strong

Based on Brandtler (2012), this paper argues that polarity items are sensitive to evaluability, a concept that refers to the possibility of accepting or rejecting an utterance as true in a communicative exchange. The main distinction is made between evaluable and non-evaluable utterances. The evaluable category comprises any clause that asserts, presupposes or entails the truth of an affirmative o

We consider the COST259 directional channel model (DCM) in relation to other existing channel models. The COST259 DCM is a general model for the mobile radio channel that includes narrowband power (field strength), power delay profiles, and directions of arrival. For comparison purposes, it is desirable that the channel models forming the basis of earlier simulations are contained as special cases

Early and accurate diagnosis of intestinal ischemia is important in order to provide rapid and correct treatment and reduce morbidity and mortality rates. Clinical signs and symptoms are often unspecific. This systemic review sums up literature regarding human plasma biomarkers for acute mesenteric ischemia reported during the last ten years. Classic, general markers, including lactate, white cell

The aim of this thesis has been to analyze the case of Google Spain v. AEDP, and the legal impacts of that particular case. One of the most important outcomes of the case was the establishment of the principle of the right to be forgotten. The definition of the principle of the right to be forgotten is to grant a data subject the right to have his or her personal information deleted and thus, maki
