Vem är ett barn? En kritisk idéanalys av Barnkonventionen
Nearly half of the worlds population is individuals under the age of eighteen. The UN Convention on the Rights of the Child state in its first article that a child is ?every human being below the age of 18 years?. Our aim and purpose with this essay is to problemize this broad definition. Our hypothesis is that the definition brought by the UN Convention on the Rights of the Child is too wide and therefore brings difficulties when children of different ages beneath eighteen should and shall be treated the same.
Vilka åtgärder kan röntgensjuksköterska tillämpa för att reducera stråldosen vid skoliosundersökning av barn och ungdomar?: En litteraturstudie
Introduktion: Skolios som drabbar barn och ungdomar ger en krökning av ryggraden i sidled. Upprepade undersökningar med joniserad strålning av främst flickor i puberteten innebär risk för bröstcancer. Genom att på olika sätt optimera undersöknings metoderna och använda skydd till patienter kan biverkningarna minskas. Syfte: Syftet med studien var att genom en systematisk litteraturöversikt sammanställa vilka metoder och röntgenparametrar som kan användas för dosreducering i samband med radiologisk skoliosundersökning av barn och ungdomar. Metod: Studien utfördes som en allmän litteraturöversikt.
Att ta vara på solens fulla uppvärmningskapacitet
The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.
Osäkerheter vid brandteknisk dimensionering av ventilationssystem
This masters thesis deals with smoke spread via ventilation systems. One aim of the thesis is to investigate and explain the differences in efforts to prevent smoke spread via ventilation systems in different countries. A second aim of this thesis is to investigate how frequently occurring smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how uncertainties in input variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed.

NATO:s misslyckande att undvika civila dödsfall i Libyen 2011
This study revolves around the NATO-led Operation Unified Protector in Libya 2011. The military campaign was executed under a UN mandate to protect the Libyan civilian population. Despite the mandate civilians died because of NATO bombings. The purpose of this study is to identify inadequate measures in avoiding civilian casualties during the operation and to continue to work towards minimizing civilian casualties caused by military organizations in international interventions.Early in the operation, NATO?s objective altered from protecting the civilians to overthrowing the Libyan regime. At the same time NATO changed its military targeting.
Vem bär ansvar för Somalias internflyktingar?
The aim of this thesis is to examine the rights of internally displaced persons as well as finding out whose responsibility it is to maintain these rights. The questions being answered are: what policies, laws and conventions are addressing internally displaced persons in Somalia (mainly from within Somalia, UN and AU)? And; which principal similarities and differences in these documents are to find regarding what type of protection internally displaced persons can get? Whose responsibility is it to intervene if these rights and rules are not maintained? To answer these questions I have used a liberal-universal theoretical framework. The analysis is a describing case study of comparative nature between the Provisional Somalia Constitution, UN Guiding Principles on Internal Displacement and the Kampala Convention. The result shows that there are many different rights of internally displaced persons in Somalia.
Kombinerat system för ventilation och rumsuppvärmning : Parameterundersökning i simuleringsmodell för takvärmesystem
A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.
Vad motiverar till ideellt arbete i ungdomsorganisationer?
Early studies of what motivates volunteering often have had an older sample and youth organizations have not been studied.

In the analysis 102 persons in age between 17 and 59 years participated. The participants ranked the motives as followed: knowledge, development, values, social, career and protection.
Klimatanpassning med grönstrukturplanering : Med exempel från Malmö stad
Climate change is expected to lead to increased rainfall and higher temperatures, among other things. This will have a major impact on our cities. Floods can lead to property damage as well as damages to human and animal health. Higher temperatures will increase the frequency of heat-related health risks and premature deaths. The consequences of climate change will be particularly large in our cities because of the city's morphology with a high amount of paved surfaces and buildings that affect the natural processes in areas such as drainage and absorption of solar radiation.

Utveckling av styrning till solföljande MaReCo-hybrid i Hammarby Sjöstad
Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.
