A Monte Carlo simulation of the ELECTRA reactor using (U,Zr)N fuel and a liquid lithium coolant is performed using the Serpent simulation code. The results show a reactor with a total reactivity coefficient of the coolant, fuel and material expansion that is strongly negative. These properties make the ELECTRA reactor a good candidate for a safe space reactor that could be used for propulsion of manned and unmanned space vehicles to Mars and other parts of our solar system..

Trough a literature study based on both philosophic and objective fact this essay is taking off in the meaning of public space. It investigates how the information society and its virtual world are affecting the idea and use of public space in the city. The city and the actual world have developed from the traditional meeting between people while the virtual world is based on flows of information. The information flow has expanded through the Information and Communication Technique (ICT). ICT covers among others Internet, mobile phones and computers.

Piglet survival is a problem of great significance in pig production, affecting both animal welfare and economic aspects negatively. In Sweden it is illegal to use farrowing crates for sows on regular basis. To encounter this problem there is a proposal of an animal welfare program to allow the use of crates for sows during, and a number of days after, farrowing. The proposal aims to reduce piglet mortality and improve pig welfare. This present review aims to analyse how crating affects the welfare of sows, gilts and piglets as well as piglet mortality.

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

The main focal point of this study is about public libraries and its possible roles in today's society. Going from having had a clear educational orientation, public libraries has with time amassed several other roles, which all need to relate to the swedish law regarding libraries and other governing documents, as well as business plans. This thesis focus on a qualitative investigation, which was conducted through in-depth interviews with librarians and other staff at a public library in Stockholm, named bibliotek Plattan, to ascertain the prevailing opinions within this facility about the role of libraries and librarians. The choice of examine this particular library was based on the fact that bibliotek Plattan differs from the public library in general and only offers material for adults. Their collection of litterature is primarily based on fiction novels.

I examine how relationships between people and objects are created and continues through contiguity every time one use or touch an object and through participation through use and memories. The aim is to continue a relationship and to keep a communication alive with people beyond time and space, then, now and henceforth. I take advantage of and transform the traces in an object that belonged to someone. Parallel I create new space for bodies to put their mark for the first time. I compare my work with the Nordic Museum's task to preserve the present for the future.

The purpose of this study is to examine whether the high school textbook on religious studies differences in how Christian ethics and in what way it is presented in comparison with the presentation of Buddhism, Hinduism and Judaism and it´s ethics. The analyzed material is textbooks from the late 1960s to the 2010s. Due to the survey´s nature the focus is first and foremost the chapters dealing with religious ethical issues and what amount of pages or space the different religions are given in the books. The results from the textbooks are compared with the curriculum that is or was effective during the time the books were published. This is done to determine whether there is a clear link between the books and the guidelines of the curriculum.

The study sheds light on pupils individual plans of development and portfolios from the perspective of children. It has an ethnographic standpoint. It was carried out on children and pupils in pre-school, pre-school class and third grade. By further investigating how children and pupils use their individual development plans and portfolios, in which settings and to whom they communicate them, this study is able to grasp the discourse that is created around the instrument itself. This study is also interested in and aims to find the theoretical frame, in essence, which envelops both the construction of childhood and children?s own activities within the limitations and opportunities that this structure offers.

The present work is a continuation of the ideas developed in previous projects during my Masters studies that explored the relation between pattern, form and space. Starting from the pattern multiplication for space construction the present project proposes textiles as an assortment of flexible expressions. The purpose of the project is to explore aesthetic and functional potential of textiles for out door temporary structures. This is to create a pattern interface which filters sunlight through a textile surface to offer instant sheltering solutions for out door activities. The project combines research and analyses of outdoor temporary structures and scope of textile in the area.

Finally the aim was to investigate if the staff encouraged the clients to break loose from the traditional gender roles. A qualitative approach using face to face interviews was used.

The aim of this master´s thesis is to explore how a library through it´s spatial distribution expresses, and is an expression for, a view of knowledge. This is done by an analysis of the Orkanen library at Malmö Högskola. Questions posed in this study are: What view of knowledge is mediated through the spatial system and in the shelving of books? What view of learning is expressed in the spatial distribution of functions and artefacts?The theoretical framework of this thesis has two fundamental features. One, which focuses on theories of social space, a part that is mainly influenced by the theories of space syntax.
