Fuktproblematik i platta på mark : En analys av uppkomsten till fuktproblem
When constructing a building, a number of aspects must be harmonized in order for it to fulfill requirements ? a building must fulfill requirements such a load-bearing, conservation of energy and a good indoor environment by means of, among other things, moisture proofing .Moisture problems in buildings can affect health negatively. As we are increasingly staying in indoors, demands on a good indoor environment are higher.This work starts with examining moisture problems in slab-on-ground solutions, and then links the various scenarios to moisture problems in a concrete slab of a real building. The building with moisture problems is located in Årby by in Borlänge and moisture damage was found in the slab at an apartment adjoining wall.By reviewing literature written within the field of moisture problem, making hand calculations and modeling in the program Comsol Multiphysics, judgments are made to find explanations as to why the rise of moisture occurred in the building in Årby by.Generally, the following guidelines may be used to reduce the risk of moisture problems in slab-on-ground constructions:Drying of construction moisture before laying the floor material.Using draining layer beneath the slab, to prevent capillary suction.Using insulation under the slab, partly for comfort and to establish the temperature difference between the ground and the concrete slab.Avoid direct contact between the wood and concrete, due to degradation and fouling smells that normally occurs.If necessary, use additional vapor barrier.In addition to the above, there are various methods for moisture-proof and moisture-monitoring by design or by the method ByggaF suited for the entire construction process various events..
Immunokastrering av hangrisar :
Active immunization against gonadotropin-releasing hormone (GnRH) is an alternative to surgical castration of male pigs to avoid boar taint. The aim of this study, including 128 pigs, was to evaluate the effect of a GnRH-vaccine Improvac® on performance and on social and sexual behaviour. Male pigs were assigned to three treatments; surgical castration at four days of age, immunization against GnRH and no castration. Vaccination was performed eight and four weeks before slaughter. Surgically castrated male pigs had significantly lower daily weight gain during the suckling period than entire male pigs (235 vs.
När visionen mötte verkligheten : en undersökning om hur arkitektur kan styra människors rörelser på studentbostadsområdet Vildanden
The essay treats how an architect can direct motions of humans with architecture. This is made through an investigation of how the architect Bengt Edman has treated accessibility and motions when creating the student housing complex Vildanden and how it has affected the motions of humans within the area. To visualize how Vildanden relates to the rest of Lund I have made a comparative study with the city planning ideals that prevailed in the period when the area was built.The essay is based on the author's own observations through a phenomenological perspective and a field study including observations and a literature study..
Youngbloods
The goal of this project was to create the music video for swedish pop/rockband Antennas? single Youngbloods, from their album Feeling Feline Tonight(2009).

The main focus for the video was to create an independent visualstory and to implement an investigation of how different technics for creatingand documenting images and motion result in different interpretations of thecontent. The work was characterized by an active search for contrasts andcontradictions.My approach to the project was to work with a child?s curiosity, but withthe discipline of an adult.
Att uppleva historia : eller publik arkeologi i Sydafrika
My thesis is based on a qualitative study in which I have selected six professional teachers in a school in Greater Stockholm, and their views on the phenomenon of conflict management. My questions were the following.How teachers perceive the phenomenon of conflict in the world of school?What strategies do teachers use to resolve conflicts with students?In order to analyze my informants, I have chosen different books that deal with conflict man-agement, policy documents and books on the teaching profession meaning. Through my investigation I found that some teachers used tools and strategies through expe-rience and reflections, and resolve conflicts together or individually. My informants described that there are some teachers how choose to hide and pretend not to see the problem.
Från ett nödvändigt ont, till en naturtyp värd att bevara - en studie av ljungheden i Sandsjöbacka och Grönabur/From a necessary evil to a nature type worth protect - a studie of the Calluna heath of Sandsjöbacka & Grönabur
In the middle of the 19th century was Calluna heath the major nature type in Halland, but the remaining parts today is only 1 500 hectares which is a 99 % decrease of the Calluna heath mainly due to an increase in forest plantations and arable fields. I have made a quantitative study how the Calluna heath of Grönabur & Sandsjöbacka has changed between 1841 and 2005 and why it didn?t disappear in the same manner, as it did in other parts of Halland. The studying of original sources as historical maps, literature and by doing field visits has been significant for the final result. The main reason for the different development of the Calluna heath in the investigation area (69 % decrease), compare to elsewhere in Halland, is the establishment and management of a nature reserve..
Annonsmediers miljöpåverkan : när ska miljön få en reklampaus?
The aim of the thesis was to investigate energy consumption and carbon dioxide emissions from an advertisement broadcasted on the radio or the television or
distributed through press. The object was to calculate the amount of carbon dioxide emissions per individual receiver of an advertisement in Sweden. There was no room
for a deeper investigation into editorial work within the framework of the thesis.
Consequently, main focus of the radio and television study was on broadcasting itself and the components involved. Focus for the press study was on paper production,
printing and distribution. Production and discarding of media equipment was not taken into account.
Lärobokens roll för undervisningen i engelska
The purpose of this study is to investigate and describe the role of course books for teaching English to children at intermediate level of primary school in Sweden. The essay is based on a descriptive, qualitative method and interviews have been conducted with seven teachers in different schools, teaching English in year 4, 5 and 6.The result of the study shows that course books have considerably influence on the teaching of English in the schools who took part in this investigation. The participating teachers use a course book as main teaching material and almost everybody follows the traditional routine working with Textbook and complementary tasks in Workbook every week. They base their lessons on course books and use alternative teaching material mainly for fun activities, speaking practice and individualization. Even though all teachers rank speaking and listening as most important for new learners, it is reading which has the largest impact on their teaching.
Pedagogens inverkan på elevgruppens beteende i klassrummet
My goal with this essay was to find out what makes certain teachers more successful than others to hold good and well functioning classes. This is important because this in turn affects the learning of the students. I wanted to find out what factors people within the world of research have pointed out as important aspects when creating a good teaching situation, with focus laying on the teacher?s behaviour in the classroom. In my investigation I have used qualitative research, observing two upper secondary school classes, for a total of nine lessons during a two-week period. In my observations I wanted to see if the class as a whole was behaving differently when interacting with different teachers.
Emballage för väggelement i trä : Paketering, hantering, lager och transport
As a company it is required to work with strategies to minimize costs such as packaging and logistic costs. The increased market of industrial produced wooden buildings results that the time and the cost which the packaging of prefabricated building elements consume, is experienced to be in greater need of development than before and demands a better solution. The aim with this dissertation was to discover how the development of the handling of the packaging can improve the packaging process. The goal was to present improvement proposals for a simplified and thereby a more efficient production in time and cost perspective.The packaging process which includes packaging, handling, storage and transport were studied. Interviews were made with participants from the market for manufacturers of wooden houses and a case study was made at the company A-hus.

Having said this, the demands on the organisation and the individuals within it will constantly increase.
HAVS ombord - en studie av hand- och armvibrationssyndrom och dess förebyggande åtgärder
On board ships different type of maintenance activities take place. Some of those require working with vibrating handheld tools. Traditionally there is a high awareness of the risks with different type of duties such as protecting the skin from oil or other chemicals, the eyes from splashes and hearing from high noise levels. The experience we have from our time as on-board cadets are that there is less information about vibration hazards available compared to the information concerning other hazards on board.There are threshold values that workers, by law, are not allowed to exceed when working with handheld vibrating tools. The purpose of this study is to investigate how common the use of this type of equipment that can cause damage by vibrations, to the hands and arm amongst the deck crew, and if the crew informed about the risks involved.

Lost World : Home of the seven and a half legged tree
The main focus for this essay is to describe the relationship between human and nature through a material investigation that takes its shape through sculpture. With the help of a fairytale-like story the reader can share the creation of the sculpture and how my thoughts flow through the process that will result in an exam project. Rooted in earlier projects I discuss the crash between civilization and the wilderness as well as talking about the likeness of the creative process and child play. I also discuss the body's place in the forest and the loneliness that we humans created that has cut us off from the rest of the creatures and plants in the forest. My aim is that in the final piece I will create a fiction place where these can be joined together again.
Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs
Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation.
Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.
