In this work, arrays of predominantly relaxed InGaN platelets with indium contents of up to 18%, free from dislocations and offering a smooth top c-plane, are presented. The InGaN platelets are grown by metal-organic vapor phase epitaxy on a dome-like InGaN surface formed by chemical mechanical polishing of InGaN pyramids defined by 6 equivalent {101¯ 1} planes. The dome-like surface is f
This paper concerns the role of teachers as street level buerarucrats in Swedish vocational healthcare education for adult students. At the center of the analysis are the challenges related to policy implementation when many of the students are second language speakers and language and communication play a role. Policy documents provide the analysis with a normative framework. Interviews with teac
Simulating evacuation behaviour in fire emergencies is an increasingly important method for assessing design to mitigate the likelihood of life losses. To date, several approaches have been used to predict the pre-evacuation time (i.e. time between the first alarm or other initial cue until the moment an evacuee starts moving toward a safe place) using distribution functions or evacuation decision
Impaired lexical retrieval is common in persons with low-grade glioma (LGG). Several studies have reported a discrepancy between subjective word-finding difficulties and results on formal tests. Analysis of spontaneous speech might be more sensitive to signs of word-finding difficulties, hence we aimed to explore disfluencies in a spontaneous-speech task performed by participants with presumed LGG
Wireless local area networks (WLAN) are rapidly becoming a core part of network access. Supporting user mobility, more specifically session continuation in changing network access points, is becoming an integral part of wireless network services. This is because of the popularity of emerging real-time streaming applications that can be commonly used when the user is mobile, such as voice-over-IP a
Popular Abstract in Swedish Dagens samhälle är mycket beroende av fordonsbränslen och kemikalier som producerats av råolja. Framtidens tillgång på råolja är oviss, det enda som är säkert är att det är en ändlig resurs. Användningen av olja bidrar dessutom till koldioxidutsläpp till atmosfären. För att säkra framtida tillförsel av energi och kemikalier till samhället och för att uppnå ett mer klimaMany scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. This interest has been enhanced by concerns about energy security and about the climate change caused by emissions of carbon dioxide. The result has been incre
Betrayal has a deep fascination. It captures our imagination in part because we have all betrayed or been betrayed, in small or large ways. Despite this there has been very little serious work on the subject. Betrayal is a breach of trust, when informants share beyond an agreed upon boundary of relations, whether that boundary is a pair of friends or a nation. Taking as a point of departure Simme
The influential scholar Ulrich Luz rejects the view of the Gospel of Matthew as an ancient biography, since he does not find any information about the education or the development of Jesus in the narrative from chapter 3. This conclusion does not give a fair description of neither ancient biographies in general nor the Gospel of Matthew in particular. Matthew actually picks up important themes in
The Constructal Theory is applied to obtain better thermal performance from a type of microchannel heat sink. Based on a smooth, straight, rectangular microchannel heat sink (Case 1), three different configurations of constructal multiple bifurcation are designed for the entrance region of each microchannel. These types are one bifurcation (Case 2), two bifurcations with the second placed in the f
Background: The thorough assessment of familial prostate cancer (PCa) risk is as important as ever to provide a basis for clinical counselling and screening recommendations. Objective: Our aim was to determine the age-specific risks of PCa and the risk of death from PCa according to the number and the age of affected first-degree relatives. Design, setting, and participants: The nationwide Swedish
The ultrafast photophysics of [Ru(bpy)(2)dppz](2+) (dppz = dipyrido[3,2-a:2',3'-c]-phenazine) embedded into the walls of phospholipid vesicles has been studied by femtosecond time-resolved pump-probe spectroscopy. While [Ru(bpy)(2)dppz](2+) has been studied intensively with respect to its intramolecular charge transfer processes, which are associated with the well known light-switch effect, this s
The photoinduced electron-transfer reactions in a Mn-2(II.II)-R-II-NDI triad (1) ([Mn-2(bpmp)(OAc)(2)](+), bpmp = 2,6-bis[bis(2-pyridylmethyl)aminomethyl]-4-methyiphenolate and OAc = acetate, R-II = trisbipyridine ruthenium(II), and NDI = naphthalenediimide) have been studied by time-resolved optical and EPR spectroscopy. Complex 1 is the first synthetically linked electron donor-sensitizer-accept
Abstract Title: Social services department’s modern centaurs – about social worker's dual role in cases of suspected crimes contribution Authors: Branislav Ros; Carl-Johan Martinsson Tutor: Lena Palvén Examiner: Elizabeth Martinell Barfoed The purpose of this study was to examine how social workers, in the social services department of economical aid, experience their dual role as helper
The purpose of this essay is to show that an individual or a group fleeing environmental change can count as what will be called core refugees. This is done by comparing the main criteria for a refugee in the refugee convention of 1951 and the African union’s refugee convention of 1969. These two conventions are used since they represent different views of who’s a refugee, even though they are rel
The role of the city is undergoing changes, and a new discourse is emerging, where growth-oriented projects plays an important role on the local political agenda, and brings increased competition between cities. There are clear indications on a shift from the local government to interactive processes with private-public partnerships that operates in a project-oriented development of the society. T
Barn har ett grundläggande behov av en förälder, en anknytningsperson, som är tillgänglig för barnet och ser till barnets behov (Bowlby, 1994). När föräldern placeras i anstalt kommer relationen mellan barn och föräldrar att ta plats inom en ram av regelverk och lagar utformade av samhället. Syftet med den här studien var att undersöka hur barns relation/anknytning till sin förälder påverkas av at
In the United States of America media and the press have the important role of being ”the fourth estate of government” which means that American media has the task to examine the political processes taking place within the country, as well as the USA's actions abroad. The importance of media not being biased or not framing certain kind of information cannot be overemphasized, but despite this,
I denna rapport har balkonginfästningar för en fastighet på Bo01-området i Malmö studerats. Fastigheten som heter Vitruvius innehåller fyra byggnader där två av dem har utkragande balkonger med intermittent infästning. Intermittent infästning innebär att den 50 mm köldbryggebrytande isoleringen som balkongerna är utrustade med, bryts regelbundet av en 300 mm betongklack. Armeringsjärnet som spänneIn this report the balconies’ abutments for a property in Bo01-area in Malmö has been studied. The property which is called Vitruvius contains four build-ings where two of them have corbelling balconies with intermittent abutments. With intermittent abutment means that the 50 mm thermal bridge insulation that the balconies is equipped with, is broken regularly by a 300 mm concrete heel. The reinfo
The study aims at exploring the links between peacekeeping operations and economic growth. The paper examines the countries in which past United Nations Peacekeeping Operations have been present and calculates the growth rates before, after and during each operation. Comparisons of the growth rates are made to show how the operation has affected the economic growth in the country. It is also discu
