Inom ett par år kommer det nya materialforskningscentret ESS, The European Spallation Source, att stå färdigbyggt. Det kommer då vara det mest avancerade forskningsinstitutet i sitt slag och leverera upp till 30 gånger fler neutroner än någon annan neutronkälla i världen. En av de viktigaste komponenterna på ESS är det s.k. strålmålet som består av nästan 7000 bitar av det metalliska grundämnet voThe European Spallation Source (ESS), which is currently under construction in Lund, will use pure tungsten as the spallation neutron target. The tungsten will be irradiated by a 2 GeV proton beam, pulsed at a repetition rate of 14 Hz. Each pulse will deposit 357 kJ in the tungsten causing an instantaneous temperature rise of approximately 100 °C, during the 2.86 ms pulse duration. The target is w

Little is know about whether the conditions experienced during ontogeny affect resistance to parasites later in life in wild animals. Here, we used a population of blue tits (Cyanistes caeruleus (L., 1758)) to investigate to what extent conditions experienced during the nestling stage could explain the ability to control blood parasite (Haemoproteus majoris (Laveran, 1902)) infections 1 year later

There still is a need for devices that allow reproducible stimulation of skin areas of the human body. We constructed a stimulation system and tested it by using brief pneumatic stimulation to the right thumb of nine healthy volunteers. BOLD-signals in response to tactile stimulation with frequencies of 1, 3 and 5 Hz were measured using a 3T MRI scanner. The stimulation device consists of syntheti

STUDY DESIGN: Retrospective study. OBJECTIVES: To optimize the radiation doses and image quality for the cone-beam O-arm surgical imaging system in spinal surgery. SUMMARY OF BACKGROUND: Neurovascular compromise has been reported after screw misplacement during thoracic pedicle screw insertion. The use of O-arm with or without navigation system during spinal surgery has been shown to lower the rat

Abstract Objective. The aim of this study was to validate externally the Swedish Lund-Malmö revised creatinine-based glomerular filtration rate (GFR) equations (LM Revised) in a Swedish cohort in comparison with the North American Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology (CKD-EPI) equations. Material and methods. The study included 1397 examinations [med

Research study was conducted from January to May, 2002 in residential areas along the Palosi Drain, Peshawar. Main objective of the study was to evaluate water quality of shallow and deep wells in the vicinity of Palosi Drain. For this purpose, 20 water samples were taken 13 from shallow wells, 3 from deep wells and 4 from wastewater in the Palosi Drain. Water samples were analyzed for heavy metal

Elasticity is the ability of a cloud infrastructure to dynamically change the amount of resources allocated to a running service as load changes. We build an autonomous elasticity controller that changes the number of virtual machines allocated to a service based on both monitored load changes and predictions of future load. The cloud infrastructure is modeled as a G=G=N queue. This model is used

Institutions for prevention and resolution of labor market conflicts were introduced all over the world in the early twentieth century. In this paper we analyze the impact of mediation on compromise outcomes in Swedish labor market conflicts, using a dataset of geo-coded strikes and lockouts from 1907 to 1927. Causality is identified by using the distance from the mediator's residence to the confl

AIM: The aim of this study was to evaluate wound healing, major amputation and mortality in patients with diabetic foot ulcer and peripheral arterial disease (PAD), and to compare the group decided to have an endovascular intervention with groups referred to conservative treatment or to those judged as unreconstructable. METHODS: A retrospective two-year review of all patients with diabetic foot

In efforts to find synergies or trade-offs between the environmental and social pillars of policies aimed at sustainable development, a key set of issues are often discussed in terms of geographical scale. The aim of this paper is to critically examine the framings of social and environmental sustainability challenges as scale-related (such as local - global or North-South) involved in processes i

Clay boards are emerging as a sustainable alternative to gypsum boards for fire protective linings in timber structures. However, their fire behaviour is still not well understood. Most existing studies focus on full scale systems, which show when a board fails but not why it fails. This thesis addresses this gap by investigating two commercial clay board variants with different compositions, dens

Aim: Allometric relationships, which describe plant growth patterns shaped by environmental conditions, reflect functional trade-offs and represent key functional traits that optimise adaptation, resource acquisition, stress tolerance and competition. Here, we assess how these allometric relationships and associated functional trade-offs drive ecosystem structure, functioning and competitive inter

This thesis follows the short path drawn by scholars in the empirical study of CE value propositions, aiming to provide answers to how firms attempt to shape urban mobility consumption in practice. For doing so, this paper takes over the empirical study of the value propositions of ten innovative shared mobility business models which constitute on its own some practical examples of circular busine

This paper presents an exploration framework which performs data assignment and access scheduling exploration for applications given a multilayer memory architecture. Our framework uses multiobjective criteria during exploration, such as application execution time, energy, bandwidth, and data size. In order to tackle the complexity of the exploration, it is divided into three phases; Pareto diagra

Popular Abstract in Swedish Det övergripande syftet för denna avhandling är att bidra till utvecklingen av en teori om förändringsarbete och lärande i arbetslivet. De specifika förändringsprocesser som studerades skedde inom ramen för en interaktiv förändringsansats som syftade till en emancipatorisk utveckling: att de anställda skulle få ökat inflytande över sin arbetssituation, vilket i sin tur

Genotyping of hepatitis C virus (HCV) is important because of its clinical and epidemiological implications. We report here the distribution of HCV genotypes in various patient groups in Finland using a rapid and reliable HCV typing method based on restriction fragment length polymorphism (RFLP) of the amplified DNA from the 5' non-coding region of the genome. The reaction product from the primary

In Sierra Leone, West Africa, there are many people with disabilities in need of rehabilitation services after a long civil war. Purpose: The aim of this qualitative study was to explore the experiences of prosthetic and orthotic service delivery in Sierra Leone from the local staff's perspective. Method: Fifteen prosthetic and orthotic technicians working at all the rehabilitation centres providi

Popular Abstract in English This thesis presents data from rainforests of southeastern Nigeria. Pairs of protected and hunted of study sites were established in three different but adjacent protected areas: 1. Mbe Mountain Community Forest (MMCF, total area 80 km2); 2. Afi Mountain Wildlife Sanctuary (AMWS, total area 100 km2); and 3. Okwangwo division of the Cross River National Park (CRNP), totaThis thesis evaluates the effect of bushmeat hunting in southeastern Nigerian rainforests on: 1) adult tree, seedling, and animal community compositions 2) germination and survival among seedlings in association with competition 3) changes in community composition at multiple trophic levels 4) leaf nitrogen concentration (LNC), leaf mass per area (LMA) and stem specific density (SSD) 5) on human r

Abstract in UndeterminedWithin cognitive linguistics, there is an increasing awareness that the study of linguistic phenomena needs to be grounded in usage. Ideally, research in cognitive linguistics should be based on authentic language use, its results should be replicable, and its claims falsifiable. Consequently, more and more studies now turn to corpora as a source of data. While corpus-based
