 En jämförelsestudie av koldioxidsläpp för en byggnad med trä- respektive betongstomme ur ett livscykelperspektiv

The goal with this examination thesis is to investigate the difference in carbon dioxide emissions between a building with a wooden versus concrete carcassing from a life cycle perspective. The huge amounts of carbon dioxide released into air from human activities must be reduced to prevent serious consequences. A way to limit this issue is through performing a comparative study where the result shows which of two products with the same function has the lowest emission of carbon dioxide, whereof the product with the lowest carbon dioxide pollution can be chosen.To be able to perform a study like this an object has been chosen and studies about life cycle analyses have been done. The rental square meter, the thermal conductivity value, the energy requirements and the placement of the building has been set equal in both framework types. There were solely dissimilarities of the two buildings taken into account when this comparison study was performed.The result of the study is that a building constructed with a wooden carcassing has the lowest amount of carbon dioxide emissions.

Solenergi i Norrra Djurgårdsstaden

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system.

Muslimska kvinnans slöja : Undersökning av hur muslimska kvinnans slöja gestaltas i läromedel

The aim of this thesis was to study how social workers in social services in several municipalities perceive that they interpret the concept of domestic violence and how they believe they would act when it comes to different types of domestic violence. The thesis has focused on three types of violence; physical, psychological and economical. Seven social workers were interviewed with a thematised interview guide and six vignettes. The theoretical perspectives applied in the analysis were the process of normalization and the continuum of violence. The results showed that the social workers did not interpret domestic violence unanimous, and they had different ideas of how they would act in the vignettes.

På drift med Spinoza och Freud

This essay attempts to examine whether it is possible to find a mutual understanding of the concept of drive between Spinoza?s philosophy and Freud?s psychoanalytical theory. Former texts on this subject have given a variety of conclusions: from a radical separation between the two authors to a complete identification between the two. The drive, or the desire which is the term Spinoza uses, has in Spinoza?s philosophy its foundation in the concept of conatus.

På vilka sätt kan ledarskapet påverka - utvecklingsfasen mot ett innovativt småföretag :  

This is a study of innovative technologies that are primarily based on collaboration with a client who in this study is called FTG, because they chose to be anonymous. A problem set has been presented, analyzed and worked with. The result of this is that we found some weaknesses in the leadership that have influenced the motivation in the workgroup negatively. The study has focus on changing leadership in order to increase motivation and openness to innovation within the company. With this focus on change in leadership, we have done a basic search for relevant theories related to the topic and found interesting data to work with.

Att klassificera arkeologi: En komparativ studie av tre klassifikationssystem

The purpose of this Masters thesis is to compare classification codes and feature headings of three different universal classification schemes SAB, UDC and DDC, when classifying archaeological literature. The aim is to determine whether a subject analysis of a title generates similar feature headings in the three systems, and to find positive and negative things about each system from an archaeological point of view. The comparison and the analysis of the 22 chosen archaeological monographs showed that the subject analysis of the titles didnt always generate similar feature headings. This could depend on several things, for example different interpretations of the subject analysis of a document, less knowledge about the system and/or the subject, or the fact that its not the same classifier that creates the codes. The study also showed that the different classification systems did treat the subject archaeology a bit differently, and that its difficult to say that one of them is better for classifying archaeological literature.

Göta älvbron, övervakning med optisk fiber : Ekonomisk analys

The Göta älv-bridge is a welded steelbridge which is located in Gothenburg,it connects the inner city of Gothenburgwith the island Hisingen. Cracks wasdiscovered in the steel in 1999-2000which started an investigation of thebridge to clearify the condition of thebridge. The conclusion was a monitoringsystem based on laser light sent throughan optical fiber.This report describes the bridge, thedamages, the monitoring system and thetraffic on the bridge.Stefan Pup, at Vectura Borlänge was mysupervisor during this work. In myinvestigation the costs of themonitoring system and the costs ofclosing the bridge is compared andevaluated. The biggest investigatingpart is the costs of closing the bridge.The results of my investigations is thatclosing the Göta älv-bridge would cost 1107 300 SEK / day.

The project has been provided by Zenit design group and the goal for this project was tomanufacture and perform tests of a prototype that supersaturates water in a continuous flow ofwater. The project has involved finding and sorting out relevant data in scientific papers, books,communication with foreign manufactures and other platforms for information.The project has resulted in manufacturing of a test rig and an oxygen infuser based onmembrane technology. The test rigs purpose was to perform tests on oxygen infusers fordifferent comparison test and performance benchmarks in a in a laboratory provided by Zenit.The project led to satisfying results using the oxygen infuser manufactured by the authors withcomparable levels of saturation to the reference infuser.The theory behind this project is based on medical research, belonging terms will be explainedbut the authors have chosen to delimit the project from the medical area. The reason for this islack of knowledge in this area and its irrelevance to the mechanical engineering education insuch..

Spelar politiken någon roll? : En jämförelse mellan Kalmar kommun och Karlskrona kommun

Currently, the whole globe is faced with serious problems which negatively affect people around the world: increased pollution, excessive waste, and weather pattern changes. ?Left? and ?right? wing political parties alike have embraced ?green? politics and for many of these parties, environmental issues have become a top priority that is very much reflected in their manifestos. This study examines the environmental goals of two of Sweden?s largest political parties and how these ambitions are reflected at a local level.

Rökning på skolgården En jämförelse mellan två olika skolors skillnader i förhållning till rökning - Smoking in the schoolyard A comparison between two different schools attitudes to smoking

Med min bakgrund som blivande geografi och idrottslärare har jag valt att undersöka rökning på två olika skolor med skilda socioekonomiska och geografiska förhållanden. Syftet med detta examensarbete var att undersöka vad det fanns för lagar, regler och direktiv för skolan gällande ungdomsrökning. Syftet var också att belysa skolornas förhållning till rökning skiljer sig åt och om det har någon koppling till vilket område de befinner sig i. Detta har undersökts dels genom den svenska skolans olika styrdokument, dels genom en enkätundersökning till rektorerna på två olika skolor. Undersökningen visade att det fanns tydliga skillnader i vilken vilket förhållningssätt dessa skolor hade till ungdomsrökning.

ACTa våra stressade lärare: en randomiserad studie om Acceptance & Commitment Therapy (ACT) för stressade lärare

The present study examines the effect of a nine-hour Acceptance and Commitment Training (ACT) intervention for teachers who experience stress. Twenty-two teachers from four different counties in southern Sweden were randomly allocated to an ACT intervention (n=15) and a control group (n=7). The ACT condition received three three-hour sessions of ACT over a six-week period, and the control group received a three-hour stress lecture at one occasion. At a follow-up four-weeks after completed intervention, ACT participants showed significant in-group differences on stress, psychological flexibility, general health, and burnout. At a between group comparison, only psychological flexibility was significantly enhanced at the follow-up.

Jämförelse mellan våtkompostering och andra VA-system i omvandlingsområden : en fallstudie i Norrtälje kommun.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

GPU accelerated SPH simulation of fluids for VFX

Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.

Ökad kollagring i boreal skog : Kan blädningsbrukad skog lagra mer kol än trakthyggesbrukad skog?

This study was conducted to test the hypotheses that a forest managed by selective cutting can store more carbon than a forest managed by clearcutting. The study was carried out as a meta-analysis. The data that was found was analyzed by performing t-tests on the proportional effect that the two silvicultural methods had on the driving factors of CO2-efflux and carbon stores in coniferous boreal forest. In all areas tested, an effect in favor of selective cutting was found, but not all of them significant however. The soil respiration following selective cutting was significantly lower than that of clearcutting, and the primary production of a clearcut area cannot according to reason exceed that of an area post-selective cutting.

Älgens barkgnag på granstammar : omfattning med avseende på geografisk utbredning, skadad volym och ekonomiska konsekvenser

In three areas in the province of Småland studies has been done to investigate how big damage the moose may do to P. abies. An inquiry examination and two different types of surveys were done to find out how big area, which volume and which financial consequences the moose debarking has had on the forest. When the volume was calculated the rot spreading was included. The area that was damaged was stipulated with the answers from the inquiry examination. 59 % of the asked forest owners answered the inquiry.
