SUMMARYInventory of raw materials holds an important role in companies within the manufacturingsector. The inventory works as a buffer that secure the supply of materials to the productionunit. The aim of the inventory is to ensure that the company is able to meet the customers?demands despite fluctuations and variations in the material flow. The size of the warehouseand the layout are physical limitations for the quantity of articles that can be stored.

This essay investigates how teacher sees and uses mainstream movies as a teaching method. The main question approached is: How does teachers use feature films as a teaching method? Which movies are used and how does their working methods surrounding the movies look like? The purpose of the essay is to make the reader reflect over what influence mainstream media has over the historic knowledge of the students and how teachers use that for educational purposes. The business around historical film has grown over the years and is now a million dollar industry. The conclusion is that teachers mostly use feature films to provoke emotional reactions from the students.

The aim of my study is to investigate how last year students in upper secondary schoolunderstand certain mathematical concepts, in particular the unit circle and its trigonometry.I have used intentional analysis to interpret student?s actions when they solve certain tasks onthe basis of a cognitive, situated and cultural context.Interviews with four university teachers in mathematics about the unit circle, trigonometry,and mathematical understanding, serve both as background for the study and as basis for adiscussion, where I relate students understanding to what the teachers want new students toknow about these concepts when they begin university studies in mathematics.The students were arranged in three groups with three students in each group. Each group waspresented with two tasks, one in which they were asked to calculate the cosine values for onepointed, one blunt and one straight angle, each located in a separate triangle. They were alsoasked to decide whether the points (0,71; 0,71) and d (1 2 , 3 2 ) are located on the unit circleor not.My conclusion is that students mainly have an operational conception of the unit circle andtrigonometry. The lack of structural conceptions result in difficulties in seeing connectionsbetween the concepts in unfamiliar situations.

It is important that children develop their communicating skills to be able to interact withother persons in different social contexts. Without the necessary skills, the child will struggleto understand others, as well as to be understood. My qualitative research takes place in a preschoolclass at a primary school in Stockholm, where I from a sociocultural perspective onteaching and learning aim to clarify how the students? ability to develop their linguisticperformance and their communicative competence is stimulated within this primary preschool?seducational framework. Empirical data was collected both through observations ofthe daily activities in the pre-school class as well as through interviews of three employedteachers.My research indicates that the educational framework in this pre-school class is structured tocomply with the official Swedish Curriculum, Lpo.

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.

The purpose of our research is to study how guidance counseling initiated by the students themselves differs between girls and boys in high school. We want to study if there are any differences between girls and boys regarding guidance initiated by the students themselves. We conducted a quantitative survey consisting of a questionnaire survey with 125 respondents. The respondents are second year students at the Science program. The result of the survey shows that there are hardly any differences between girls and boys regarding guidance initiated by the students themselves.

This thesis concerns waste management on construction sites and was conducted on behalf of ICA Fastigheter.Areas of concern:How can an environmentally-efficient waste management system on construction sites be defined? What potential exists for exploiting the waste resources that are generated?How can the waste management be optimised by reducing the quantity of waste and by optimal sorting?How can the client of a project influence the waste management?The purpose of the work was to investigate sustainable waste management in the building and construction sector and to highlight waste as a resource from an environmental and economic perspective.The aim of the work was to define an environmentally-efficient waste management system, to analyse the potential that exists in waste management and to draw up guidelines for optimal waste management.The method consisted of a literature study, two visits to construction sites and four interviews.An environmentally-efficient waste management system means that the waste is managed in the following order of priority:Prevention     Reuse  Recycling     Energy recoveryLandfill     The prevention of waste is an important area that has not been adequately explored by the building and construction industry. The quantities of waste could decrease with the implementation of measures such as ordering materials in the dimensions required, prefabricated components, logistics centres with Just-In-Time deliveries, less and improved packaging and less wrapping. The reuse of waste materials and temporary apparatus as well as the use of a return pallet system are examples of reuse that reduces the quantities of waste.In most cases the source sorting work is a matter of course and the proportion going to landfill is down at a low level. The source sorting can be optimised by sorting all materials that can be reused and recycled to use them as a resource.

In a multicultural society such as Sweden opposition between different ethnical groups can be hard to avoid. In the educational arena there is legislation and there are guidelines that aim to avert any kind of xenophobia directed at individuals or groups. As teachers occupy the end point of the educational chain the execution of these guidelines is for the most part left up to them.This paper aims to study how teachers handle situations where xenophobia is present and if so how they work preemptively against it. It also takes a closer look into the notion of professionalism within the teacher force with the aim of trying to answer whether teachers reach the requirements of professionalism. To do so we apply Gunnar Berg?s definition of the term 'professionalism' together with other scholars' thoughts on the subject.

The purpose of this essay is to closely study different studies and texts within the subjects ofanimals and nature in order to, from different themes, analyze and determine whether or not animalsis a useful tool to apply in school as well as preschool. Above all else, this study serves to answerwhat animals and nature can bring children, and when you as an educationalist can benefit from it inyour classes within school and preschool. This study also serves to point out what you should keepin mind when using animals as a tool in your classes, since there are a few obstacles to consider.The method used to analyze the different themes is discourse analysis, which is a sort of textanalysis.About one hundred years ago when our society was industrialized, different theories and theimportance of preserving and to sojourn into nature began to grow among some theorists, biologistsand educators. The value of spending time outdoors was realized, which we today have a greatunderstanding of. Our interest for the impact of animals on us is also starting to grow, and there is alot of research that is of the opinion that animals are good for children in many different ways, andfor many different reasons.

In this essay, I examine teachers' different approaches, responsibilities and child perspective on preschool. I discuss how important it is that we educators in preschool work together as a team about childcare and learning. Our attitudes affect the children.In the essay, I show examples of different attitude and approach to learning and the significance of the educational awareness that characterize the work of the nursery. We have different approaches and standards that are influenced by our cultural, social and ethnic backgrounds. It plays a major role in how we interpret and understand various situations in preschool.I also discuss preschool teacher's responsibility and teamwork, and how it affects children.

This study focuses on the Nordic model of Extended Collective Licenses (ECL) and how this model can be used in the process of digitalising and publishing archival material such as photos, letters, maps or films. The question that this study aims to deal with is what advantages, and disadvantages, there are for archives and copyright holders when an ECL is being used. To help answering this question the ?theory of the knowledge commons? has been applied. The research question has been answered through a text analysis based on legal texts including Swedish law.
