The concept of function represents a major part of mathematics and becomes more significant in school during high school. Throughout history, it has been a difficult concept to define and may create challenges for contemporary students. This literature study aims to identify students' difficulties with the concept of function, as well as to account for how the definition of a function has evolved historically. The literature study has been conducted through database searches in ERIC, Education Research Complete and MathSciNet via EBSCOhost, as well as through chain searching. The study results in identifying that students' difficulties with the concept of function primarily include the graphical and algebraic forms of representation.

There are numerous questions to be asked when your task is to plan a small community?s future development. Is it possible to suggest something new and modern? What considerations should be taken concerning the existing situation? What is an appropriate size for the new development? Where is it possible to build and what is the most appropriate method to use?In this master´s thesis I have tried to develop and describe a working-process where I execute a complete landscape character analysis for the whole community in question to get the answers to where and how it would be most appropriate to develop a village like Flädie without destroying its current character.Flädie is a typical small village in the countryside of Skåne, Sweden. It is strongly effected by the expansive and urban region it?s located in but is still rural in character.

This final year project is made for Peab Jönköping and its target group is the construction industry. The main focus is the use of unutilized building material in the most economical and environmental-friendly way. Unutilized building material is here defined as material purchased for a construction project that for different reasons not has been used. The most important thing to find out was how much building material considered as being waste is actually useable material, and how much less it costs to use that building material instead of throwing it away.When this information was gathered a proposal on how to efficiently use the unutilized building material instead of wasting it was designed. Costs and incomes were investigated and the proposal suggested a storage area where Peab can store their unused building material.

In preparation for the autumn term in 2011, the Swedish elementary school adopted new syllabuses regarding, inter alia, the civic education (Sw. Samhällskunskap). The civic education has traditionally been a disciplinary subject with a main purpose of mediating democratic values as well as providing generalorientation in the society. Generally, the civic education intends to reflect the world in which people live in, being a complex society which to a large extent is regularly affected by global aspects and developments.      The purpose of this study is to review all the elementary school?s syllabuses relating to the civic education with specific focus on the globalisation perspective.

The jetengines of today are growing in complexity. Reliability for aircraft engines are of extreme importance, mainly due to safety reasons but also economical ones. This master thesis deals with faultdiagnosis in the turbine section of RM12, the engine used in Saab/BAe's Gripen. Three different faults which can occur in the turbine section was studied. These faults are: clogged fuel nozzle, hole in outlet guide vane and sensor fault.

Uppsatsen syfte är att undersöka vilka faktorer som haft betydelse för kvinnor som befinner sig på höga ledarpositioner inom omsorgen. Uppsatsen har genomförts med hjälp av kvalitati-va intervjuer av fyra kvinnliga stadsdelsdirektörer, varigenom bidragande och motverkande faktorer kartlagts för vägen till positionen. Även resurser och strategier de kvinnliga ledarna använder sig av för att klara av påfrestande situationer i arbets- och privatlivet och hur de kombinerat sitt privatliv med sitt arbetsliv kartlades. Uppsatsen genomfördes utifrån Kanters organisationsperspektiv och Antonovskys känsla av sammanhang. Resultaten visar att inter-vjupersonerna troligen har en hög känsla av sammanhang, genom att ha resurser och ett spekt-rum av strategier för en livssituation med låg stressnivå och positiv stresshantering.

The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.

Using leaching test is a way to get a picture of pollutants retention and leaching in a risk assessment on contaminated land. There are several different types of standardised leaching tests today, where the natural leaching processes are speeded up to make it possible to predict the leaching of pollutants. These leaching tests have been developed for waste and there are no specific guidelines on how to judge the results from the tests, when making a risk assessment on contaminated land. This work is an investigation on how to use leaching test in this type of risk assessments. The strengths and weaknesses of the different types of tests are discussed. Depending on what type of information you want from your leaching test, different types of tests are suitable.

Det är ett övervägande antal flerspråkiga elever av den grupp elever som inte uppnår godkända betyg i skolan, vilket bland annat beror på att undervisningen inte tar hänsyn till deras språkutveckling. Det medför att många flerspråkiga elever inte förstår undervisningen de deltar i. Genom förståelse inhämtar eleverna kunskap och utvecklar sitt språk, vilket ger goda möjligheter att nå skol- framgång. I denna uppsats belyser jag problematiken runt undervisningen i vår mång­kulturella skola där syftet är att söka svar på vad en god undervisning innehåller. En ledstjärna har varit vad Hajer & Meestringa (2010) talar om som ?språkinriktad undervisning?.

The aim of this master?s thesis is to investigate a information center called ?Infoteket om funktionshinder?. The purpose of Infoteket is to collect information about disabilities and make it accessible to people with disabilities, their relatives and public. In this survey I will analyze how Infoteket can help people with disabilities to achieve empowerment. I use empowerment as a theoretical framework as Jay A.

Syftet med studien var att beskriva hur distriktssköterskan upplever införandet av valfrihets­system i primärvården. Vidare var syftet att beskriva varför distriktssköterskan stannar kvar inom den landstingsdrivna primärvården då nya privata aktörer finns tillgängliga. Studien hade en beskrivande design där tio distriktssköterskor från en stad i Mellansverige blev inter­vjuade. Det insamlade materialet blev transkriberat och analyserat med hjälp av kvalitativ innehållsanalys. Resultatet strukturerades i två innehållsområden.

It is a common-held belief that the social worker for the most part uses oneself as a ?tool? in working with clients. This study seeks to examine that ?tool? in the context of treatment of teenage boys with psychosocial problems such as criminal behavior, drug-abuse and/or abusive home environment. The main purpose is to identify the conceptions of masculinity, and more specific hegemonic and subordinated masculinity, of the professionals working with the boys.

Energy efficiency has become a very topical issue that has been discussed throughout the European Union for preventing negative environmental impacts that have been associated with the consumption of energy. In the residential sector have mainly municipalities set strict requirements for the reduction of energy consumption while the renewable energy has been asked. Different concepts of low-energy buildings have been developed to reduce the cost of operation and maintenance in existing buildings such as in new ones.This thesis has aimed to minimize the energy cost of a large building which has had low energy consumption features originally. Energy reviews has been initiated in order to be able for showing how the house electricity could be carried out even more efficiently.The work was initiated through a literature study to clearly increase the reliability on the energy subject. Different concepts of low-energy buildings have been treated in connection with its specifications, afterward those have been compared with the obtained results.

High demands are set on all equipment used in emergency service work, where small margins can be the distinguishing factor between life and death during a rescue operation. It is important that tools such as ladders quickly and easily can be dismounted from a vehicle and still satisfy the regulatory requirements for securing loads during transport. The existing solution for getting ladders down from the roof of a fire engine requires a large manual effort from the user in an ergonomically unsound posture.In this degree project a new ladder holder is developed with focus on the user to solve the ergonomic problems and at the same time create a more compact design that can be adapted to several different types of ladders. After an initial pre-study with user-interviews and measurement of forces and distances a set of requirements was formulated that came to govern the project's direction. Creative methods were used to generate concepts that improved the function and through design solutions, calculations and testing in CAD a base for manufacturing of a new product was created.The result is a completely new type of ladder holder that minimizes the user's manual effort and simplifies the securing of ladders in the holder.
