A patient positioning system for Boron Neutron Capture Therapy (BNCT) for treatment of brain tumours was designed, and its accuracy was evaluated. The system will be used at the BNCT facility under construction at Studsvik, Sweden. Recent studies have shown that the accuracy in the patient positioning procedure in BNCT is of more significance than generally perceived in the past. Therefore one obj

Denna kandidatuppsats är en litteraturstudie som behandlar jökulhlaups och deras tillhörande landformer samt deras inverkan på landskapet. Jökulhlaup är den isländska termen för störtfloder från glaciärer och används internationellt för att beskriva detta fenomen. Vattnet som skapar dessa störtfloder kan ha många olika ursprung, såsom kraftig nederbörd, snabb avsmältning av glaciäris, tömning av eGlacial outburst floods also known as jökulhlaups are important features connected with glaciers globally. They may induce catastrophic floods as well as new landforms. This review describes and synthesizes jökulhlaup trigger mechanisms as well as associated landforms and landscape impacts of jökulhlaups with a special focus on Skeiðarársandur, south Iceland, and the 1996 jökulhlaup. Important sou

När rovfåglar flyttar använder de antingen glid- och kretsflykt eller en kombination av glid och aktiv flykt. Energikonsumtionen vid aktiv flykt ökar snabbt med ökad kroppsvikt och används därför oftast av mindre rovfågelarter så som falkar, sparvhökar och kärrhökar. Glid- och kretsflykt används till mycket stor utsträckning av de större och tyngre arterna som vråkar, glador och örnar, som då är bRaptors migrate by using either soaring and gliding flight or a combination of gliding and powered flight. The energy consumption when using powered flight increases rapidly with body mass and is therefore mainly used by the smaller raptors, such as Falcons, Sparrowhawks and Harriers. Soaring and gliding flight are mainly used by the larger raptors such as Buzzards, Kites and Eagles. When using so

Den boreala skogen, mer känd som taigan, breder ut sig på de nordliga delarna av norra halvklotet innan den trädlösa tundran tar över. I detta enorma skogsområde som sträcker sig genom Skandinavien, Ryssland och Nordamerika är störningar i form av bränder, insektsangrepp och stormar vanliga och en naturlig del av ekosystemet. Dessa störningar påverkar skogens kolbalans genom deras inverkan på bådeNatural disturbances such as fires, insect outbreaks and windthrows are able to influence the balance between the ecosystem gain and loss of carbon in the boreal forest. This effect of natural disturbances on the ecosystem carbon balance has been proposed as one of the reasons why the CO2 concentration in the atmosphere varies between years. At present the boreal forest as a whole act to mitigate

Abstract The aim of this study was to make a survey of different perspectives on “voluntary” prostitution in Thailand, which we tried to accomplish by semi structured interviews with people who, in some way, were connected with the field. Their occupations stretch from a student writing his thesis to a human rights lawyer. This study has centered around four areas concerning prostitution in Thaila

Sedan 1975 har det funnits en utökad möjlighet för patienter att få ersättning vid felbehandling inom vården genom den frivilliga patientförsäkringen, utöver de möjligheter som skadeståndsrätten erbjuder. År 1997 var patient-försäkringen inte frivillig längre, då det lagstadgades att varje vårdgivare är skyldig att ha en patientförsäkring och förutsättningarna för ersättning fastställdes. FörutsätSince 1975, the possibility for remedy when Swedish healthcare is performed incorrectly and causes personal injury is extended by the voluntary patient injury insurance. Since 1997, the patient injury insurance is statutory in the Patient Injury Act and thereby mandatory for all health care institutions. The conditions for compensation through the patient injury insurance are the same regardless o

In this thesis the background characteristics as well as the mobility and productivity of Swedish inventors is investigated. Swedish inventors tend to be highly educated, with an education in engineering or natural sciences. They are to a large extent male and in their mid-forties. Since there is possible an endogenous relationship between mobility and productivity, instrumental variables applied

Remittances are getting wider attention in recent years because of the enormous increase in amounts. Remittances have already outshined the inflow of FDI, official development assistance, and portfolio flows for many developing countries. However there is no clear-cut understanding of its macro level importance to economic growth which arises because of shortage of study in the area. This study tr

Poverty has previously been viewed as one of the most important drivers of the HIV epidemic. However, recent studies have found that poor individuals are not more likely than wealthy to be HIV positive. Therefore, economic inequality together with gender inequality has instead been suggested as the main socioeconomic drivers of the spread of HIV. The studies analyzing the relationship between econ

Export promotion policies are widely used in most countries. The aim is to increase exports to foreign markets and in this, Sweden is no exception. In this study, my objective is to investigate whether Swedish export-promoting activities abroad, realized through the Swedish Trade Council (STC) and the Foreign Service (i.e. embassies and consulates), are associated with higher aggregate Swedish mer

Development is often looked upon in economical terms and often research tries to investigate how one country can produce or sell more in order to increase its GDP. This thesis does not exclude these considerations but focuses on health as an important aspect of development. I investigate why South Africans (SA) would place their lives at risk with full knowledge of AIDS by not using freely availab

The G20 leaders forum was created as a response to the economic and financial crisis of 2008-2009. However, well before the crisis, calls for a new order in global economic governance had mounted as the credibility and importance of existing patterns of global governance had waned. Accordingly, the G20 replaced the G7 for dealing with international economic matters and designated itself as the pre

Behovet av information på värdepappersmarknaden ökar i och med att det blir allt vanligare att investera i aktier. Aktiebolag vänder sig till värdepappersmarknaden för att skaffa nytt kapital till bolaget. De främsta anledningarna till detta är att bolagen vill finansiera sin verksamhet, ofta i form av nyinvesteringar, samt att ägarna vill kompenseras för de investeringar, både i form av nedlagt aThe increased importance of information on the securities market correlates to it having become more common to invest in shares. Business corporations turn to the securities market in order to raise money. The main reasons being the will to finance their operations, often in the form of new investments, and the owners wanting to be compensated for their investments, both financially and in terms o

Individuals do not only make decisions to maximize their own utility, but are also concerned with how their decisions affect others. Theories of inequality aversion, taking fairness considera¬tions into account, suggest that many people dislike inequalities between themselves and others. Testing for inequality aversion is easiest done by using experimental economics, in this paper in the form of a

The main objective of this paper is to empirically assess debt-relief as a mechanism of aggregate poverty reduction in severely indebted and middle-income countries. The empirical analysis focuses on the channels connecting growth to investment and social spending that are believed to fuel the resource development gap of the heavily indebted countries that have suffered from the debt crisis. In or

Abstract The research sought to present a deep analysis on the formation of identities in Jamaican children living in garrison community in the context of community violence. A phenomenological scientific and theoretical approach was applied, focusing on lived and imagined experiences formations. Data was collected using open interviews from six children, age nine to eleven. The obtained text was

Since the financial crisis of 2008 many European countries have been plagued by growing fiscal deficits and public debts. The country found by many to be the worst off is Greece and in this study we use the Solow model of economic growth to attempt to find a savings level for Greece which provides enough capital for both investment and debt service. We use two different scenarios where one is base

Fair Trade has noticed a new form of involvement for the public and the private sphere in relation to consumption. The aim of this study is to explore ethical consumption in relation to Fair Trade as well as the political aspect of it which has been relevant for supporting global causes and a form of citizen participation. The data collected for the study are an in-depth semi-structured interviews

Palmolja finns numer i en rad olika produkter, från margarin till biobränsle, och den globala efterfrågan på palmolja ökar år för år. I Malaysia har produktionen av palmolja ökat mer än 185 gånger sedan år 1961 och idag producerar landet omkring 40 % av världens palmolja. Den enorma tillväxten drivs av bland annat populationsökning, förändrade konsumtionsvanor samt policys som syftar till att öka There is a growing global demand for palm oil – a vegetable oil used in various products such as margarine and biofuel. Since 1961 the Malaysian palm oil production has experienced a 185-fold increase and currently Malaysia produces about 40 % of the world’s palm oil. Malaysia also has one of the world’s richest flora and fauna. The palm oil industry has gained much negative attention in recent ye
