Produktutveckling av flytbarhetsutrustning

Detta examensarbete omfattar produktutvecklingen av en komponent till en mätutrustning som ska mäta flytbarheten hos smält metall. Arbetet har utförts hos Bryne AB och har lett fram till koncept-, material- och tillverkningsförslag för komponenten. Arbetet har även utvärderat ett för gjuteribranschen nytt formmaterial som alternativ till dagens gjutsand. Tester har gjorts för att se om återvunnet (material x) går att använda som formmaterial till högtemperaturapplikationer..

Att gå från det konkreta till det abstrakta, att det blir konkret för barnen. : En undersökning om hur lärare använder och värderar laborativa material i matematikundervisningen i skolår 1-3

Syftet med detta examensarbete var att undersöka hur lärare använder olika laborativa material i sin matematikundervisning i år 1-3 och hur detta överensstämmer med det sätt som upphovsmännen till materialen avser. Mina frågeställningar har bland annat varit: Vad är laborativa material?, Hur använder lärare laborativa material i matematikundervisningen i år 1-3?. För att söka svar på dessa frågor har jag genomfört en litteraturstudie, och en kvalitativ intervjustudie med åtta lärare som använder laborativa material i sin matematikundervisning. Resultatet visar att det finns skillnader mellan hur lärare använder vissa laborativa material och hur materialens upphovsmän beskriver att materialen ska användas.

Konstruktionsleken ur pedagogers perspektiv. : En studie om hur pedagoger tänker och arbetar när det gäller konstruktionsleken i verksamheten.

The purpose of this study was to examine how teachers act when it comes to play with constructions in preschool. The purpose was also to find out what kind of material the children have to work with and what they do with the things that the children made. The study was based on qualitative semi-structured interviews. Semi-structured interviews was choosen  to get out as much information as possible, with open questions in a semi-structured interview you can get the information that is relevant for the study. The results show that there are different kind of material available in preschool, but knowledge of the subject is missing and demanded by teachers. The material are pretty similar, some of the teachers use material from the forest while others don?t.

Jämförelse av stenull- och polyuretanisolering : Brand- och fuktegenskaper i passivhuskonstruktion

This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results.

Laborativ matematikundervisning i årskurs 5 : En jämförelse mellan lärare och elevers uppfattning angående användningen av laborativt material

Under de senaste åren har intresset för användningen av laborativt material ökat markant. Syftet med denna studie är att ta fram och göra en jämförelse mellan lärare och elevers uppfattningar och åsikter angående användningen av laborativt material i matematikundervisningen. Studien har genomförts på fyra lärare i Örebro samt deras klasser i årskurs 5. Resultatet visar att laborativt material underlättar lärandet, gör matematiken roligare och mer intressant, för många enligt både lärare och elever. Lärarnas och elevernas uppfattning om hur ofta laborativt material plockas fram och då finns tillgängligt skiljer sig åt.

Jehovas vittnen i Sverige i ljuset av sekularisering : Deras metoder för att motverka sekulariseringens effekter

The reason behind this essay has been to study if previous research is relevant for Jehovah?s Witnesses in Sweden and see if secularization has affected the organization or not. The empirical material is made from two qualitative group- interviews and open observations during two meetings in the Kingdom Hall. These studies were performed in Oskarshamn and Mönsterås during the month of February. The reason that these studies have been limited to Oskarshamn and Mönsterås is mainly because they were the only ones willing to do an interview.  According to previous research by James A.

Resurssnåla materialflöden - En fallstudie på Volvo Powertrain

From the customer?s perspective the only reason for a firm to exist is the value it creates. However, a problem within manufacturing companies is that of the total lead time, only a small part can be considered as value adding. It has further been discovered that when working with improvements businesses often sub-optimizes single processes instead of considering what benefits the entire company. Thus, when improving processes and activities it is important to have knowledge about and understand which factors that affect how the flow can be designed.Several studies have been performed with a wide perspective on process flows in order to obtain a more resource-efficient and value added flow.

?En ja?vla freakshow? : Representationer av maskulinitet i svensk wrestling

The aim of this thesis is to examine representations of masculinity in the activities of a local professional wrestling promotion. After briefly outlining what professional wrestling is, the study draws on a body on feminist and intersectional theory which critiques the notion of gender as a binary and essential category. The material comprises 10 recorded shows and oth- er material published on Sthlm Wrestling?s website between 2010 and 2013, and is analyzed using a qualitative methodology derived from cultural studies. The thesis argues that there are many different types of masculinities in the narrative, which are constructed in relation to different power hierarchies such as ethnicity, class, sex and sexuality.

Fadern, Sonen och Partnern: representationer av ett faderskap eller en helt vanlig treenighet

The thesis explores representations of fatherhood in the Swedish blog 'Hemliga pappan' ('Secret/Anonymous Daddy'). The purpose is to identify three themes in the blog material; The Father, The Son and The Partner. I have performed this study using discourse analysis as methodological tool and Critical Studies on Masculinities and Fatherhood as theoretic approach. The theories are Social Constructionist and consist of sociologists and socio-psychologists as Connell, Hearn and Johansson. Important theoretic concepts are the presence and absence of the father as well as hegemonic masculinity.

The properties of this material has been studied and it was found that there is very little difference in what affect students in there choice of school, studies and career. Boys who choose hairdressing and styling differ more than girls who choose a career in technics. This is a surprising result which we didn´t expect. In researching background material we learned that it should differ more in perspective of gender. We have compiled the material around young people's choices to high school.

Kulturers påverkan på förhandlingar

In this thesis, I discuss the impact Swedish national culture may have on Swedish diplomats. This is a qualitative study and I have used theories from studies of international negotiations to compare the oppositional results of those scientists with my interview material. With the help of my interview material from seven Swedish diplomats and five foreign diplomats I have compared their perceptions of Swedish culture, Swedish diplomats and their thoughts about the existence of an international diplomatic culture with well known sceientists of international negotiations. My main question is whether there is an international diplomatic subculture, without any national impact, or not. The mission is to base the thesis with earlier science and then compare and contrast with my interview material.
