?Killar skriver inte puttinuttigt? : En experimentell studie av genusföreställningar i textbedömningar

This thesis examines conceptions of gender revealed by people when assessing texts. The research questions are: What associations can be discerned between gender conceptions and ideas about the quality of texts? What features of content and style are perceived as female or male? The study seeks to develop a method for comparing different people?s assessments of the same text. The material was collected by means of questionnaires in which 114 informants were asked to assess three anonymous student texts and then guess the sex of the writer. The material has been analysed quantitatively by correlating the assessments of the texts with the guesses about the sex of the author, and qualitatively, as the informants? freely worded assessments of the texts were analysed for content and form with the support of assumptions about how assessments are expressed in text.

Kvalitetsförbättringar och Emballageinstruktioner

This report is the result of a thesis carried out at the Department of Innovation, Design and Technology (IDT), at Mälardalen University on behalf of ABB AB Machines.The year was 1988 when ASEA and Brown Boveri formed a joint venture under the name ABB (Asea Brown Boveri).We perform our thesis at the division Discrete Automation and Motion where they primarily develops, manufactures and sells synchronous and asynchronous AC motors and generators.The main purpose of this thesis was initially to write a general packaging instruction, but the priority changed to develop more specific packaging instructions for Rotors, Stator gables, Bearing support and Outer Cover (plates) instead.The work started off to deal with a problem about that the staff had to start its work to grind away rust on the stator gables due to those stored outdoors. The result was mainly an investment in a new gable rack so that the material can be stored inside, as well as a packing instruction as it was originally intended.The problem on the bearing supports were that the staff thought it was demanding and difficult to clean them from the rustproofing they were greased in. If it is not possible to remove all rust protection it can cause the paint to not attach properly. After having compared with similar articles a test were done to order a pair of bearing supports without corrosion inhibitor, which gave good results. This initiative also set in motion a process to do the same for more different items.For special pallet, a survey were made of the process with two different VSM and a calculation of how much ABB would earn at ordering more special pallets than getting the material delivered on the A-pallets.

Observiaire och film som analysmetod för cykeltrafik : En fallstudie på Götgatan i Stockholm där omställningen till supercykelbana utreds

The goal of this thesis is to analyse whether the method ?Observiaire? is of any use for traffic analysis. The method consists of analysing film material, preferably before and after changes are made to an area, by answering a survey for the users that are observed within the population. The method also opens up for deeper qualitative analyses which are rooted in the quantitative data collected from the survey-study. In this study we analyse the method by applying it to the case study of the changes made at Götgatan in Stockholm, where a green wave was implemented and the bicycle road widened.

Förbättrad styrning av ingående material

Detta arbete har syftat till att undersöka möjligheterna till förbättring av material- och produktionsstyrning vid Sandvik Mining and Construction i Sandviken. Målet har varit att skapa ett underlag för förbättrad styrning av ingående material. Nulägesanalysen visade att förbättringspotential fanns inom klassificeringen av hårdmetallämnen och komponenter. Dessutom var det önskvärt att ett kanbansystem uppfördes på de förslipade hårdmetallstiften som går till den helautomatiska STAMA-cellen. Examensarbetet har gett underlag för en omstrukturering av denna klassificering men även för en framtida uppdatering av den.

Uppbygnad av ett logiskt flöde vid produktionsövertag

The situation at Plastal AB is following; the plant in Simrishamn has not capacity enough but the plant in Kristinehamn has unused capacity. My task with this master thesis is to build a logistic flow between this two plants, optimize purchase quantities and ensure delivery safety.The production of the Intermediate Section (LS) will be divided between the plants. The LS will be produced in the following way; the injection moulding process will be done in Simrishamn and the assembling and lacquering processes in Kristinehamn, The reason to divide the production is to ensure delivery safety. Plastal AB can not move the whole production of the l.S because the two plants have different processes (moulding res. injection moulding).When the 1.5 has been transported to Kristinehamn following moments are included in this order; lacquering, welding and assembling.

Strö- och vattentilldelning hos ett urval av Halmstad kommuns svinbesättningar

This thesis is conducted together with the environmental- and health department in Halmstadcommunity. The thesis is about allowance of bedding and water supply for pig farms inHalmstad community. These farms are chosen randomly from all of the pig farms inHalmstad community. It includes inspection of 27 pig farms and writing of a report. Duringthe inspections I study the amount of bedding, what kind of bedding, water supply andinjuries like lameness, shoulder-bone sore, ear-, flank- and pig tail biting.

?Konsten är att sovra i allt material? ? om val av material och aktiviteter i ämnet svenska som andraspråk

BAKGRUND: I vår bakgrund redogör vi för den tidigare forskning som bedrivits kring fysiskt undervisningsmaterial i ämnet. Vår teoretiska ram utgörs av Cummins modell för andraspråksinlärning samt Vygotskijs sociokulturella förhållningssätt vilka båda ligger till grund för vår resultatdiskussion.SYFTE: Syftet med vår undersökning är att med utgångspunkt i klassrummets konkreta material studera undervisningssituationer i ämnet svenska som andraspråk, samt undersöka vilka motiv lärare anger för sina val av material och val av aktiviteter.METOD: För att nå studiens syfte använde vi oss utav observationer och kvalitativa intervjuer. I vår undersökning ingår tre lärare på olika skolor som undervisar i ämnet svenska som andraspråk.RESULTAT: I vår undersökning fann vi att lärarna arbetade med ett varierat material och olika aktiviteter i sin undervisning utan att vara styrda av läroboken. Gemensamt för de tre lärarna var att de arbetade med skönlitteratur, läsförståelse och ordkunskap. Resultatet visade också att lärarnas motiv till det material de använde ofta grundade sig på en ambition av anpassning till elevernas tidigare kunskaper och vardagliga liv..

Nya renings- och uppgraderingstekniker för biogas

Biogas is a renewable energy source that is produced by anaerobic digestion of organic mate-rial. In Sweden, biogas predominately comes from sewage water sludge and landfills or from organic waste of households and industries. Small scale digestion plants at farms are espe-cially expected to contribute to increased biogas production in the future. Biogas can be ob-tained directly in it?s raw form and used as fuel in a combustion chamber.

Teknik för egen foderberedning :

There is an uncertainty in the market for grain forcing the meat/milk producers to review alternative feeds to a larger extent, in order to get control over the feed costs. This has led to that the meat/milk producers need to have a good knowledge regarding how the different feeds influences the animals and which technical equipment to use for handling. For those that produce their own feedmix, there is a need to put interest in new crops and their characteristics to be able to get the knowledge of what is required for their own production. It is beneficial to keep an open dialogue with advisors to be updated in new crops and new technology for feeding. When mixing feed at farm level, the legislation is not very clear since it the target group is large scale mixing plants. We have brought up the most important rules and regulations from the EU parliament Council as well as the ones from the Swedish Board of Agriculture (SJV), regarding feed mixing on farm and factory level. We have studied beans and pea at two different moisture levels, in order to evaluate how the moisture level affects the distribution of particles when milling with a plaitmill and a hammermill.

GNSS-Styrning : Information för platschefer

An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.
