Experimentell undersökning av provkroppar för trälimfogar
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.
Musikers karriärvägar : Flöjtisters karriärvägar och utbildningars påverkan
If guidance counselors are to do as good a job as possible, they need to have as much comprehensive information as possible when it comes to possible career paths for their clients. To get on the way to get this information I, in this study, examined how musicians - specifically flute players career paths could seem. I examen this by doing five interviewees. This study is for guidance counselors, so they hade a more solid foundation to stand on, but also for aspiring musicians to get new perspectives to consider when faced with career choices.The study is conducted through five interviews with professionals flutists; Agneta, Harry, Jenny, Eva and Pepita who all work or have recently worked as professional musicians or teachers. With professional musician, I mean the ones in one way or another is or has been employed musicians and also is in the same or higher level in terms of their music ability than those who are employed.
Effektivisering av produkionsflödet för stora cylinderrör på Företaget AB
This study was conducted in autumn 2008 on the Company AB, which is currently in a growth phase. The company manufactures hydraulic systems for the heavy vehicle industry and has annual sales of approximately 250 MSEK with 165 employees.The rapid growth and unchanged planning is the starting point for this report. It all began in 2005 when the company received an unusually large order. During this period, the first priority was to satisfy customers and all other focus was disregarded. This has primarily resulted in a messy production and long throughput times.
Förstärkning av betongkonstruktioner med kolfiber med avseende på olika brottstyper
The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe..

The report aim to increase awareness of factors that have a major role whenremodelling an apartment building from the 1950s to offices.The thesis can be used for future projects when remodelling apartments to offices.The report can provide ideas and inspirations on how this can be done in aneffective way, ie . A way that does not require rebuilding the supporting structure,but only non bearing walls. The thesis also gives insight on the parts that will needto be supplemented from Boverket?s requirements in terms of accessibility,acoustic and fire requirements.The methods used in this thesis are literature studies, case study and sketch work.In the literature studies, the primary sources were Boverkets byggregler BBR, andArbetsmiljöverkets föreskrift AFS 2009:2 but other literature were also used. Theprimary items were chosen from the literature studies and they were furtheranalysed in the sketch work.
Tidsmål inom akutsjukvården: En studie av Södersjukhusets akutmottagning
The 1st of January 2009 a new goal was set for the emergency care in Stockholms läns landsting. This new goal stated that 70 per cent of the patients shall not spend more than four hours in the hospital when requesting emergency care. The processes in the emergency room at Södersjukhuset do not cope with this new goal. The authors studied the reasons for this and made suggestions based on the findings. The conclusions were that the emergency room should place doctors much earlier in the emergency care process or implement a system where specialists act as tutors to non-specialized doctors.
Ambulanspersonals uppfattning om fysiska tester och fysisk träning inom ambulanssjukvården
There is no standardized test to control the appropriate physical ability in the Swedish ambulance service. The county in question does not perform annual physical tests. A project has been going to develop science-based physical tests, designed for the ambulance service. The research has resulted in the Aasa-test.Objective: The aims of this study were to examine the ambulance staff perception of the Aasa-test relevance, introduction of annual tests and the importance of their own physical training in relation to ambulance work.Method: A quasi-experimental study with a comparative design has been conducted. Aasa-tests were conducted in 41 randomly selected staff at an ambulance station in central Sweden.
Delaktighet hos barn i behov av särskilt stöd : En studie om hur möjligheten ser ut för barn i behov av särskilt stöd att få vara med och påverka vardagen i förskolans verksamhet
Earlier studies shows that democracy within the preschool is an important and on-going work, but could implicate certain consequences. For example that goals regarding democracy and influence in the preschool, rarely is done in practice but instead remains just words on a paper. It could also mean that the pedagogues lack education and knowledge within the area, but also how they react to the influence of children. Preschool is expected to be a place for all children, no matter what luggage the child is carrying. The luggage is filled with the life experience, the personality and in this case the needs that the child has. The needs could be anything from nearness to physical and psychological disorders that requires more pedagogical attention.
"Det är konstigt att det är svenskar som är minoritet i den här skolan i Sverige" : En undersökning av elevers identitetsskapande i relation till den mångkulturella skolan
It is in a time of changes when the human being mainly seeks for its identity. In today?s globalized and internationalized society where people meet whom belongs to various religions, talks different languages and are carrying on different values and previous experiences. This has resulted in a multiculturalism and diversity in the "Swedish school". As a teacher and pupil in this school of multiculturalism you are daily faced by individuals that either you define yourself as or in relation to.The purpose of my study is for me to show how pupils with foreign background look on the multicultural school, and also how they create their identity in relation to the diversity offered by the school.
Offentlig upphandling av ekologiskt producerade livsmedel : Ludvika kommuns, Borlänge kommuns respektive Smedjebacken kommuns erfarenheter av gruppcertifiering enligt KRAV
The Swedish public procurement correspond to approximately 400 milliard Swedish crowns every year which corresponds to about a fourth of the Swedish Gross National Product. Setting proper demands in the procurement is a useful tool to drive the development towards more environmentally adapted products and provisions. The Act on Public Procurement (Lagen om offentlig upphandling, 1992:1528) gives the municipalities opportunities to consider environmental properties during the procurement. This combined literature and empirical study investigates the experiences made by the three municipalities Ludvika, Borlänge and Smedjebacken during the process of certifying their school kitchens as organic in cooperation with KRAV. The main conclusion is that without compassion and curiosity for developing a green public procurement changes can be hard to implement.
Teknik för vårskörd av hampa till stråbränsle :
Hemp is an annual energy crop that fits very well in Swedish crop rotations. It is an interesting crop with many benefits, for example its ability to establish a large quantity of biomass in one year. Hemp is easy to grow and out-competes unwanted weeds through its aggressive growth pattern without the need for pesticides. Interest in growing hemp and other energy crops is currently decreasing, apparently because of high grain prices. These high prices give a higher net profit that we believe could partly cover the cost of hemp cultivation, while the hemp in turn would improve the crop rotation and thus repay its debts in the form of increased yields of other crops.
The great disadvantage of hemp is the lack of knowledge about spring harvest of the crop.
Att bygga i trä eller lättbetong : en jämförelse mellan väggkonstruktioner
Hudiksvall Municipality will build a new preschool. The goal is that the pre-school should reflect the municipality's environmental goals and meet building regulations. The wall structures that are compared in the report is an insulated wooden frame and a frame of lightweight concrete blocks from H + HWall structures are compared within the areas of U-values, air tightness, thermal storage capacity, fire ratings, moisture, durability, emissions and environment. In these categories the two wall structures will be rated in a scale from 1 to 5 and then the categories are weighted against each other. The weighting is based on Hudiksvall Municipality's assessment of the categories importanse for their final selection.The results of the comparison show that the concrete structure is recommended for the construction of pre-school with 27.55 points against the wooden structures 23.70 points.
Energioptimering av Hemsö fästning med förslag på energieffektivare systemlösningar
The report is a master thesis about energy efficient measures for an underground facility Hemsö fortress.Several proposals are evaluated economically.Statistics of the electricity used and measurements of several heat pumps are analyzed to find energysavings potentials.The results indicate that several units of a dehumidification system are responsible for over 70 % of theyearly electricity cost. The air that is being dehumidified by these units can otherwise cause damage ofculturally important interior designs.The proposal with highest profit suggests an alternative method for dehumidification. The cooler in theair handling units in Hemsö fortress have capacity to dehumidify the air. However complementary fansneed to be installed to circulate humid air towards the air handling units. The solution can be implementedin three different locations within the facility.
Födoval hos juvenil piggvar (Psetta Maxima) : effekter av bytesstorlek
The effects of prey size on prey choice in different cohorts of juvenile turbot (Psetta maxima)were studied in three nursery areas at Gotland. Prey length measurements showed that gobies(Gobiidae) increased in average length during the season, while mysids (Mysidae) did not.Experiments on predation capacity of different size classes of turbot on different size classesof prey showed that juvenile turbot easily can eat gobies that are up to two thirds of their ownbody length, while the body size of turbot does not have any effect on the predation capacityon mysids. Stomach content of 217 turbots, less or equal 35 mm, was analysed to see if therewas any change in diet during the season, but there was no significant change in diet. Theoverall conclusion was that early settlers most likely have an advantage due to greater accessof alternative prey..
