Analys av Nedbrytningsprodukter av Polymerer för Bitumenändamål

This project was aimed to study the degradation of polystyrene-butadiene-styrene block copolymer (SBS). SBS is used to modify bitumen, the binder in asphalt. From earlier studies it is known that SBS degrades in bitumen, but the degradation products have not been identified. To be able to determine the long term effects of SBS in the environment, degradation products need to be identified. Polystyrene forms rigid blocks with polybutadiene as a rubbery matrix between the ridgid blocks.

När backa inte längre var ett alternativ : Genomförandet av Arenastaden i Växjö

This thesis suggest an explanation for is how it is possible to understand that the large arena project in Växjö grew to cost sums of money that initially in the project not would have been an alternative to discuss, how goals changed and how the institutional environment changed the prerequisites of the project. As empirical part of the research, to describe and analyze the project, the municipality?s documentation of the project have been analyzed and semi-structured interviews have been made. Theoretical perspective is taken from the neo-institutionalism in sociology of organizations and change, and theories of the complexity of large projects with major symbolic value and importance. The project starts with the municipality?s investment and cost to be hold back, defined as a necessary condition in order to fulfil an ambitious drive towards new sport arenas.  Eventually the necessary condition was abandoned and the arenas were built with the municipality responsible for the investment, cost and risk in the project.

Läraren - från ensamvarg till lagarbetare? : En studie av hur lärarrollen har definierats och förändrats i grundskolans läroplaner från 1962 till 2011.

Forming teacher teams is currently the standard way of organizing teachers in Swedish Compulsory Schools. This is the result of a process that started in the 1970s.Traditionally the culture of teaching has been one of isolation. Once the door to the classroom is shut, what happens behind the door is up to the teacher to decide. Over the past thirty years a lot of time has been dedicated to making fundamental changes in the way teachers interact with their colleagues. Today the idea of teachers forming teams is generally accepted but still the core of a Swedish teacher?s job is that of a lone worker.

Sametinget: en institutionell analys

The Saami, a Nordic indigenous people scattered over four countries, has for centuries been regarded as parts of the national populations of the countries in which they live. During the 19th century saami demands for greater influence resulted en several changes, among them the founding of a Swedish Saami Council in 1993. The council became a popularly elected, representative institution with an agenda of its own, but also a public authority answerable to the government. The decision to attribute the council this twofold role was unusual and, from a certain point of view, even controversial: it makes it difficult to determine the location of the power to act in saami-related issues and the legitimacy to do so.This essay is about how the twofold role came into existence, what it leads to and how the seemingly contradictive duality is managed. It has an institutional approach with theories concerning institutions and etnicity as well as institutional change and handling of complicated and ambiguous demands.

Tidssynkroniserade mätningar i vattenkraftstationer

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

Kunskapshus eller offentligt vardagsrum? En undersökning av Lunds stadsbiblioteks ombyggnad

In this study my aim has been to discover what connections can be made between the way of creating a library building and the general values concerning the library activities and the library users. What kind of ideology could possibly be reflected in a library room? My study includes two different parts. First of all there is a theoretical section based upon literature relevant for the subject. Here I try to focus on the libraryÕs role in society as a public room.

Utanförskapandet - en diskursanalys av begreppet utanförskap

In this essay my aim is to examine how the term utanförskap is constructed and defined as a social problem in the public arena of the Swedish Parliament. The term utanförskap was widely used in the election-campaign prior to the Swedish Parliament election in the year 2006. The term, mainly articulated by the Right-wing Alliance, was used to describe indi-viduals and groups that were depicted as being outside the Swedish society. In the political debate, work and benefit dependency were constructed as binary opposites, with the latter describing the individuals in utanförskap. Translated to English the term utanförskap would be something like ?the state of being outside? or ?outsidership?.

Utveckling av takra?cken fo?r sla?pvagnar

This report is a bachelor thesis work in the field of product development and design. The assignment has been to develop a solution for roof racks, normally used for cars, to fit on the open trailer models FS1425 and Alugance. The project was implemented by Johan Andersson and Victor Karlsson, students at the Mechanical Engineering program with a focus on product development and design at Jo?nko?ping?s school of Engineering, in spring 2012.The client wants to use transport solutions in the same way as roof racks on cars. The user of such a product is assumed to desire simplicity, safety and an attractive design with an appealing price, which has been a challenge during the thesis work.Pre-studies have been conducted to examine the potential competitors and gain knowledge in the research area.

Skolbiblioteket på friskolorna : en studie av friskolorna i Lunds kommun med fokus på de verksamhetsansvarigas inställning

The purpose of this master thesis is to examine the opinion about school libraries among principals at the independent schools in the municipality of Lund. In order to fulfil my purpose I used a qualitative method with an introductory questionnaire, which gave background material to the interviews. All seven principals answered the questionnaire and five of them agreed to participate in an interview. Another two interviews were made with two informants, this material was included in the background material. As theoretical framework I have used literature about the school library development, the role of the principal for development and David V.

Optimerad lagerhantering

Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.

Beredskapsvattenförsörjningen på Sjukhuset i Varberg -En källa till problem?

The hospital in Varberg has a somewhat outmoded solution regarding the state of preparedness in its water sustentation. Today?s solution is both cause to a number of mishaps and high energy consumption.The report is initiated by looking into the present situation to get an insight to the problem.Today?s media depletion is measured and analyzed.Furthermore, it also looks into some earlier performed studies. These studies are followed up in order to see if measures have been taken.The report presents a number of arrangements which should be taken, amongst those a minor re-build of the current solution and a number of arrangements which leads to decreased water consumption..

Humanioran och Open Access ? en kvalitativ studie i drivkrafter och strategier hos litteraturvetare inför publicering

The natural sciences and the humanities are associated with differentpublishing patterns. Open Access publishing are mainly associated withthe publishing patterns of the natural sciences. Many Swedishuniversities and research funders are proponents of Open Accesspublishing, what will that trend mean to the scholars with a publishingpattern not corresponding to Open Access? In this paper literary scholarsare interviewed for the purpose of learning the motives and strategieswhich form their publishing pattern, and how they relate to Open Accesspublishing. The results show that literary scholars are less competitiveand hold a more gentle knowledge-sharing ideal, than natural scientists.The drive to gain acknowledgment and the recognition of colleagues inorder to collect academic capital as Bourdieu describes the academicfield is still present though.

Är plöjningsfri jordbearbetning bättre än konventionell plöjning? :

The background of this study is the fact that it nowadays is more common to grow wheat after wheat. Usually we plow every autumn to remove the straw, and we wanted to study the effect of alternative methods to do it. We have done this experiment to answer the question if no tillage is better than conventional plowing. The results of the field experiment indicate that there is a link between plant establishment and the choice of equipment, but also a higher weed pressure in experimental plots with only ground tillage. The equipments which left much straw on the top of the ground the problems with fungi were more severe.
