Kvinnors preventivmedelsanvändning under olika faser av det reproduktiva livet
Introduction: Studies have shown that women are not always satisfied with the effects of contraception and that contraceptive advice is perceived as non-specific. Aim: The purpose of this study was to investigate what contraceptive women have chosen to use in the different phases of their reproductive lives, and what they felt had influenced their choice. Method: A retrospective cross-sectional comparative study with a quantitative approach. A survey with fixed and multiple-choice options was sent to five hundred 45-year old women. Result: The study shows that various birth controls are different in the normal reproductive life.
Känslan av att aldrig passa in : En kvalitativ studie om unga finska romers erfarenheter av att tillhöra en minoritetsgrupp
Romanies have long lived outside the fabric of society and have long been exposed to discrimination in Sweden as well as the rest of Europe. The purpose of this study is to elucidate the experiences of young Finnish romanies in their everyday lives as well as their perceptions of living as a minority group in Stockholm today. Previous scientific researchers have often concentrated their studies on the romanies as a group, so we, the authors have chosen to concentrate our research on the individual?s own experiences. We, the authors have chosen to use a qualitative approach, to give us the opportunity through using open ended interview techniques to comprehend and interpret the individuals own accounts.
Igloo
This degree project has been performed along with Classic Garden in Gothenburg andBallongfirman Far & Flyg in Stockholm. Together we have developed a sun- wind- andrain protection. The protection is permanently assembled and mainly intended for publicenvironments as restaurants and outdoor cafés.The design on the sun protection was already done so our task has been to develop theconstruction and to build a prototype in scale 1:4 and one in scale 1:1. The look of thesun protection is approximately as the name implies, equal an igloo. The lamellae aregoing to fold out in different steps all the way down to the ground and the both sides willbe independently of each other.The first stage in the project was to develop differently principle proposal on how thefunction will work when folding in and out the protection.
ENERGI- OCH KOSTNADSEFFEKTIVAMATERIALVAL I VÄRMESYSTEM : En jämförelse av rörmaterial i vattenburna värmesystem
The thesis aims to compare differentpiping materials in heating systems interms of cost as well as to illustratethe impact of energy characteristics ofdifferent materials over its servicelife.

Vibrationsdämpning av värmepump
Thermia Värme AB is one of the market leading manufactures of heat pumps. In order tomaintain this position, the company wants to improve the vibration characteristics of theirproducts. The aim of this thesis is to develop product design changes that lead to a reductionof vibrations in the heat pump Thermia Diplomat 8.The main cause for vibrations in the system is flow pulsation and mechanical forces inducedby the scroll compressor. Vibration is transmitted through the compressor piping and receivedby the heat exchangers, from where it is further transmitted to the connection points for theradiator and heat source circuits.A number of design changes in order to improve the vibration characteristics have beenevaluated through calculations and practical experiments. The changes have included thecompressor and heat exchanger mountings, the compressor suction and discharge line pipingand also pulsation dampening.The results of the experiments show that the vibration levels in the connections for the heatingand brine circuits can be decreased strikingly through changes in suction and discharge linepiping.

Putnam first wrote about the causes behind the regional differences in economic and political development in Italy, the theory of social capital has truly flourished in the fields of social science. This days you constantly hear politicians and scholars stressing the important role of the quality of the social fabric to a society?s wellbeing. There all looking at ways to construct policies and institutions that help the spread of social capital.
Gestaltning med vinterfägring : tre förslag på prydnadsplanteringar för Storgatan i Lomma
Detta är ett kandidatarbete i trädgårdsdesign som behandlar gestaltning med vinterfägring. Genom ett mentorsprojekt mellan Lomma kommun och SLU fick jag en förfrågan av parkchef Lennart Persson om att utforma gestaltningsförslag med vacker vinterfägring. Syftet med arbetet har således varit att utforma tre intressanta och inspirerande förslag med praktfulla prydnadsplanteringar för området intill Storgatan och Karstorpsvägen i Lomma. I arbetet finns också en platsanalys som bygger på Catherine Dee?s teori The seven-part morphology.
Studie av en medeltida husgrund : en analys av bronsfynd från husgrund 6, Västergarn, Gotland
This essay is an analysis of the objects made of bronze found in an excavation Västergarn parish, Gotland, in 2010, conducted by the University of Gotland. The studied material presented in this essay comes from contexts inside, as well as nearby the foundation of a medieval building which purpose is still not certain. The first purpose of this study is to present the bronze-objects found inside and nearby the foundation of house 6, and to see if there are any datable objects. There is also a discussion whether there has been any bronze-crafting in the area. The second purpose is to make a contextual analysis to see if there are any differences between the material found outside and inside of the building, and what conclusions can be made regarding the function and use of the building.

Barnoveraller är ett specifikt område inom klädesbranschen. Det ligger lång produktutveckling bakom, som har pågår under ett flertal år, vilket har förbättrat slutprodukten vad det gäller material, beläggningar och sömnadstyper.I B-uppsatsen finner du lättare materialinformation, konstruktionsinformation, nationella samt internationella standarder, krav ställda ifrån tre olika företag och utav ?barnoverallskunden?. Det här samarbetet blir vårt försök att bidra till barnoverallsmarknaden.Vi har utgått ifrån vår referens, ett privatägt barnklädesföretag från Bollebygd, Sverige.1 De har gett oss möjlighet att få vara med i produktutvecklingsprocessen och leta förbättringar som kan gynna slutprodukten och 2bseen som företag. Det har också gett oss möjlighet att skänka något litet (en sammanställning) som kan användas av fler företag i liknande bransch och situation.2bseen önskade sig ett samarbete där vår roll skulle innebära en fortsatt produktutveckling på befintliga produkter som i produktion fått ett och annat fel.Childrens clothing is a particular area of clothing business.
Rening av metallhaltigt avloppsvatten : En teknisk/ekonomisk utvärdering av reningsmetoder för metallhaltigt avloppsvatten
This Master?s Thesis aims to investigate and assess the methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna.Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste water.Assa has four plating lines: the Trumline, the big Zinkline, the new Zinkline and the Decorativeline. The new Zinkline is the most modern of the four lines and purification is done byrecirculation over an ion exchange unit. The demand for fresh water is thereby heavily reduced.The Trumline, the big Zinkline and the Decorative line all use older techniques.

Kalciums och magnesiums inverkan på arsenikavdrivningen i virvelbäddsugnen : The influence of calcium and magnesium on the expellation of arsenic in the fluidized bed furnace
In the fluidized bed furnace at Rönnskärsverken, Skelleftehamn, sulphur-containing ore concentrates are roasted in order to remove about 50% of the sulphur in the incoming ore concentrate. This occurs in order to reach the goal of a matte containing 55% of copper in the following smelting process. At the same time as the ore concentrate is partially roasted pollutions as arsenic, antimony and bismuth are expelled. Earlier made thermodynamic calculations of equilibrium suggested that calcium and magnesium form stable compounds with arsenic and thereby inhibit expellation of arsenic in the fluidized bed furnace, an element that is undesired. The purpose of this thesis work was to gain knowledge of the mechanisms behind the formation of these stable arsenic compounds.
Klädesfabriken : Textilförläggaren Anders Hansson på Mölneby i Östra Frölunda en protoindustrialist i 1800-talets Sjuhäradsbygden?
The purpose of this paper is to survey the textile based proto-industrialism in Sweden in the middle of the 19th century. This case study is founded upon Anders Hansson?s pre-industrial textile production at the estate of Mölneby, Östra Frölunda in the rural district of Kind in the province of Västra Götaland.Account books from the year 1853 related to Anders Hansson?s wool fabric manufacturing have been looked into and categorized using a quantitative research method. The research has also been supplemented with a number of interviews.The result of the survey shows that Anders Hansson?s business activities fit into Mendel?s theory of proto-industrialists at a practice level.By collaborating with a merchant in Gothenburg the fabrics were traded in unknown markets, as well as in more familiar neighbouring districts.
Förekomst av tenn och koppar på bottenmålade fritidsbåtar 2011
Det har uppmärksammat att det fortfarande förekommer tenn och koppar från båtbottenfärg på fritidsbåtars skrov trots förbud av båtbottenfärger med tennföreningen TBT sedan 1989 och reglering av kopparbaserade färger sedan 1999.Syftet med denna kandidatuppsats är att ge en dagslägesrapport vad gäller förekomst av tenn och koppar på fritidsbåtars skrov.Under våren 2011 har tester på 336 fritidsbåtar i tre vattenområden gjorts med hjälp av en handhållen XRF (X-Ray Fluorescence, röntgenfluorescens) som genom avläsning av en yta visar halter av olika grundämnen. Testerna utfördes på vinterförvarade fritidsbåtar <12 m hos båtklubbar vid Mälaren, Storsjön och Härnösandskusten. Undersökningen visar att 73 % av båtarna i denna undersökning har halter av tenn och/eller koppar överstigande >2500 ppm, vilket är det för rapporten satta riktvärdet. Det innebär att de skulle kunna tas vidare till kemisk testning med till exempel gaskromatografi kopplad till masspektrometri (GC-MS) för att avgöra exakt vilken substans färgen innehåller. Resultatet visar också att användningen av tennfärger antingen fortfarande förekommer i liten skala eller att gamla tennfärger är så pass starka att de ger utslag genom övermålade färglager.
Tillgänglighet och varsamhet i vardagens stadsmiljöer
This graduate thesis deals with the challenges facing us as we gradually make our urban environments withtheir many public buildings, such as shops, cafés and cinemas, more accessible for disabled people. Theperspective taken is that of the conservationist, who in her or his profession looks to the cultural andhistorical characteristics in buildings and building environments. In order to gain better accessibility, changesin the physical fabric need to be made, with consideration for the cultural and historical characteristics.The introduction presents the subject of considarate accessibility. The second chapter deals with the legalaspects concerning the protection of buildings as well as the accessibility for disabled people. Severalinterviews with different participants are presented here, aiming to tie the legislation to the reality of theconservationist, the disabled, the civil servant working with accessibility issues and the property owner,whose responsibility it is to make the adjustments necessary to improve accessibility.
