Dragbrotschning av invändiga profiler
High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.
Skogen i barnlitteraturen : Kan den fungera som en källa till naturvetenskaplig kunskap?
The amount of various phosphorus (P) fractions in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated. Sediment samples were collected along three transects from the inlet to the outlet, with six samples in each transect. In order to measure the soluble P, an NH4Cl extraction was done. This was also analysed for total soluble P after oxidation with peroxodisulphate.
Accelererat åldrande av produkter Apelsinjuice och hallondryck
Brämhults Juice AB is one of Sweden?s leading producers of fresh fruit juices and drinks. The fruit drinks last 3 days once opened and when stored in a refrigerator kept at 7°C. Since factors that shorten the drinks? best before date are usually not noticed until the entire batch has expired, it would be advantageous to find a way to accelerate the drinks? natural deterioration, so that an unusal short best before date is noticed before more products are shipped off to the stores.
Event Marketing : En alternativ väg till kund lojalitet
Marks do not only work as an acknowledge of the effort that has been made under a long period of time, but also as a receipt for eligibility to further studies. Within the political debate, marks have often caused a big discussion among the political parties. That is due to the obvious difference between the political parties on the left, and their counterparts on the right. However, there is one thing that they all have in common. Everyone of them have plans of measure within their political agenda, regarding the use of marks.The aim of this study has been to try to understand the way pupils think about marks.

En avpolitiserad politik? : en studie av hur jämställdhet konstrueras i SKL:s Program för hållbar jämställdhet
Gender equality is a political issue that has gained a lot of support in the last decades. Researchers have however pointed out that gender equality has a wide variety of understandings.SKL (Sveriges kommuner och landsting) is an organization that looks after the interests of local authorities and county councils in Sweden. SKL has by the government been granted 145 million Swedish crowns to support gender mainstreaming at a local level. During a period of three years, 2008-2010, funding has been given to 89 projects for this purpose.The aim of this study is to examine what meanings are given to the term ?gender equality? in these projects.

Man behöver inte vara officiellt deprimerad Om biblioterapi som biblioteksverksamhet, med Kirklees i England som exempel
The purpose of this thesis is to examine if and how bibliotherapy can be part of ordinary work in Swedish libraries. Questions: what is bibliotherapy and who can work with it? What are the conditions required? What does it mean to people taking part and to libraries? In this study bibliotherapy is delimited to fiction and activities including discussions, excluded are self-help books and the individuals private reading. The study is based on four qualitative interviews with librarian and bibliotherapists in Kirklees, England, partaking in nine bibliotherapeutic sessions and a literary survey, together forming a case-study. Conclusions: There is not a single answer to the question what bibliotherapy is, but if one puts stress on the biblio- part of the word, seeing reading as a normal activity it can be part of library work, whereas the therapy- part should be dealt with by professionals outside libraries.
Den offentliga upphandlingen implementeringsproblem.
This thesis is a cultural theoretical case study of the art project (O)önskad samhällsförbättring.Via an analysis of the project, that is based on theories of power, resistance and contemporaryurban development, it examines the construction of urban space, its impact on public art including the ability of art to initiate evolvement of the urban public space.The last decades art has plaid an important role in what is called the creative city; to become attractive nodal points of the global economy, larger cities increasingly invest in art,culture and creative industry. Simultaneously the urban public space is limited to activitiesand expressions of art that are presumed to create economic growth. This introduces animpression of what is allowed and what is not allowed, possible and not possible, wished andnot wished which, as a consequence, evolves the public space. The events during the artproject and the reactions that followed enlightened these limitations. This tells a story, not only about the structuring process of the local urban space, but also important changes that are created as a simultaneous effect at different levels in society, as well locally as globally.
Strömningen i och över en skog : utvärdering av en 'mixing-layer' hypotes
A new theory for predicting the windprofile over a canopy has been evaluated. The theory was first presented by Harman and Finnigan (2007). The theory relies on the forming of a mixing-layer above the canopy, due to different mean wind in and above the canopy. Characteristics from both mixing-layer and Monin Obukhov similarity theory have been used to develop the governingequations that give the wind profile. The theory has been used to calculate wind profiles for sixdifferent atmospheric stabilities.

Bilden av Östasien : Hur östasien framställs i gymnasiets läroböcker i historia
Textbooks are a very influential medium considering the fact that they often introduce students to information they have never read or heard about before, and as such they become very important in forming students? opinions on different matters. In this study I have taken a closer look at five textbooks in history that are currently being used in the Swedish upper secondary school. My aim has been to find out how East Asia is pictured and also how much space East Asian history is given in these textbooks with the postcolonial theory as theoretical basis. My study shows that East Asia is given very little space compared to Europe in these books, with an average of less than a twentieth of the number of pages that deal with European history.
Distriktssköterskans tillvägagångssätt vid blodtrycksmätning på vårdcentral
Inledning: Distriktssköterskor har ett stort ansvar gällande blodtrycksmätning samt uppföljning av patienter med risk för hypertoni eller som behandlas för hypertoni inom primärvården. Blodtrycksmätning är en undersökningsmetod som förutsätter att den utförs korrekt med hänsyn till felkällor och rätt förfarande för att mätvärdet ska kunna tolkas rätt. Det finns ett flertal olika riktlinjer för hur standardiserad blodtrycksmätning bör utföras. Att arbeta hälsofrämjande är grundläggande i distriktssköterskors förhållningssätt och samtal kring livsstilsåtgärder är en viktig del i samband med behandling och förbyggande av förhöjt blodtryck. Syfte: Syftet med studien är att kartlägga hur blodtrycksmätning går till vid besöket hos distriktssköterskan samt vilka aspekter som tas upp i samtalet i samband med besöket.
(O)sociala medier? : En jämförande kvalitativ attitydundersökning om människors användning av sociala medier och dess inverkan på deras liv och umgänge
This essay aims to find out what impact social media have on the daily lives of Swedish people in regard to their usage and sociability. In order to find that out we have performed four group interviews with a total of 16 people from two different age categories that were later compared. To analyze the empirical data we?ve used the theories on the Network Societies by Jan Van Dijk as a help of understanding. The results show that social media have become an integrated part in the lives of our informants and that a consdierable amount of time is spent on them everyday. In the younger group Facebook was considered the most useful medium as it makes the planning of events easier and can be used as a way of keeping oneself updated on news as well as on the lives of others.
Effekter av tidiga reflektioner vid musikreproduktion
In this project the focus has been on the system for recombination at Oskarshamn 2. The recombining systems have on several occasions switched paths due to low pressure before the last ejector that?s feeding the recombiner. Of the mentioned reason, events and several measuring points have been analyzed in this report since the installation of the recombining systems.In order to prove theories and demonstrate what may be the cause of this problem, we used heat balance calculations by the program Probera. Using the program, we can demonstrate that the catalytic process does not reach the desired temperature with the amount of combustible substance.
