Trademarks are distinguishing marks that are used by companies to highlight their goods or services to separate them from other companies. In Sweden, trademarks are protected by a certain Trademark Law called Varumärkeslagen. The law is a result of many years of improvements from earlier trademark laws. Since Sweden is member of the European Union, its laws are affected and in many cases inferior to laws of the Union. A new Trademark Law is about to be implemented in Sweden, thanks to a directive from the European Union.When a trademark is registered it is possible to use the symbol ® along with the trademark.

The aim of this bachelor thesis has been to investigate some of the materials present in and onprinted papers which might be suitable for analysis. A brief history of paper making and somepigments were studied after which the theory of some of the available methods for technicalanalysis were summarized. Two works of art on paper were chosen for a closer examination,both are woodblock prints but of different composition and origin. The investigation wasmade to exemplify some of the common techniques applied on works of art. There were twoaims in these examinations.

The purpose of this study has been to compare teachers' differing methods of teaching mathematics and their perspectives on the learning process in a municipal school to a Waldorf school. The study has examined which approach best promotes student engagement and learning in mathematics in the first three years of schooling. The study is based on four interviews. The informants? accounts are interpreted using theories from previous research.

It is important that the language in textbooks for foreign language learners reflects the language that the learners would encounter in real life. For this reason, the presence of the thousand most common nouns in two Swedish textbooks in Spanish for upper secondary school is observed in this study. Furthermore, this study aims to examine how these nouns occur in order to determine if their pattern of occurence favours the learning and consolidation of words. The main materials that have been used are A Frequency Dictionary of Spanish by Davies (2006) and the word search program available in the digital versions of the textbooks. The results show that the presence of the thousand most common Spanish nouns does reflect the frequency information presented in the frequency dictionary but not all thousand nouns are included.

En av Parocs produkter är sandwichpanel som är ett byggmaterial som kan variera i storlek och tjocklek och är funktionellt och smidigt. Uppdraget var att designa ett beslag för panelsystem som minst 50% av Paroc Panel Systems kunder skulle föredra framför de gamla, främst med avseende på estetiken, men även baserat på lätthet att montera och kostnad av beslaget. Projektet skedde i samverkan med företaget Paroc Panel System AB och ur förundersökningen framkom att utseende, monteringsmöjligheter, egenskaper såsom materials livslängd och hållfasthet och totalkostnad var viktiga krav som ställdes på produkten. Lösningsförslag med fokus på flera viktiga aspekter togs fram och kombinerades till olika koncept med hjälp av en så kallad morfologisk tabell. En konceptutvecklingsfas ingick där hållfasthetsberäkningar och materialval var avgörande.

Efforts to achieve a moisture proof construction process have proved to be considerably complicated, despite the knowledge and awareness that now exists within the moisture field. Materials, documents, templates and checklists are designed to be accessed but are not used anyway. This may be because such effort has not been prioritized and properly requirements have not existed from the commissioner of a building.This report illustrates how the commissioner of a building project can achieve a moisture proof building process by increasing knowledge, moisture proof planning, and implementation of security moisture routines. Proposals are given on how the commissioner of a building project can work to consistently bring a moisture proof building process in all stages. The difficulty with regular moisture proof efforts, the authors believe is mainly due to the following points:      Many different design solutions.      Lack of experience feedback.      Lack of communication.      Financial incentives.      Attitudes.The interviews in the report have conducted with the help of a qualitative analysis, while the survey has been done using a quantitative analytical method.

To save energy it?s popular to build houses with low energy loss. In these houses the walls are keeping a lower temperature in the external side which leads to a higher relative humidity. In addition more material, such as wood studs, are used which means that there is more moisture to dry. More moisture in combination with higher relative humidity may pose a higher risk of microbial growth.

Violence against teachers in Swedish schools, according to recent reports has increased and there have been many studies to investigate the situation for teachers. The surveys show that teachers are especially vulnerable to students. This study aims to examine the relationship between a number of teachers and their students to study the power relations that exist in the classroom. This is to see what violence is an expression of and also how violence is perceived by the teachers. The issues that are central in this study are:What is the importance of dialogue in the relationship between these teachers and their students?Is there power relations between teachers and their students?What is the violence against teachers and expression of?Is there any connection between dialogue, power relations and violence?The theories of the materials in this study was analyzed using power relations theories of the historian of ideas Michel Foucault and Philosophy Doctor Anders Persson, who to some extent has his theoretical basis in Foucault?s power relations.

The purpose of this thesis is to examine how teachers work and reflects on gender education in preschools. We also want to take part of how teacher?s thoughts are reflected in the physical indoor environment and how the environment is designed by reviewing the rooms furnishing and the selected materials. We will do this by visiting a number of preschools located in Stockholm and New York. We have chosen three questions to get the answers on our purpose.How teachers reflect around gender pedagogy are, and how the thoughts are expressed in the practical work.How the teachers communicate with their co-workers about gender pedagogy.How the teachers own thoughts and reflections on gender pedagogy have been expressed in the physical indoor environment where the children stay during the day. We have used interviews and observations as a method to gather the information that we needed to answer our questions of the thesis.

A lot of houses built during the Million Homes Programme are in need of major renovation. Today?s technology and materials are better than in the 60?s and 70?s. Both Swedish government and the European Union have set climate goals regarding energy consumption by 2020 and 2050. Achieving these goals would require better standards in buildings than the Building regulations demands, such as Umeå municipality?s construction requirements for new buildings.The report aims to investigate if a renovation of apartment buildings from the Million Homes Programme can reach Umeå municipality?s construction requirements.

The purpose of this research is to study the new curriculum in the topic of modern languages in the upper secondary school, and compare the curriculum from year 2011 with the one from year 2000 and thus try to find differences in the content and wordng. The research also aims to investigate teachers' interpretations and understanding of the new curriculum. The study is divided into two sub?studies and those are based on the two methods of text analysis and interview. Text analysis of policy documents is made parallell with some aspects found in the background materials of the upper secondaryschool reform, which can be summarized as precision and globalization.

The construction industry is always looking for ways to make the work more efficient aswell as minimize the waste of money in general. At the same time the industry is showing alow awareness of logistics which has to increase in order to improve the industry in thesekind of questions. Projects located in the inner city have high demands on the logistic andthe handling of material due to the so often limited space for storages of the material. Dueto this the purpose of this report is true a case, study and analyze what kind of factors thereis to take into consideration during the materials way from the supplier to the workstationin a project located in the inner city. The data for the report was collected with the help of acase study, and in three different ways.
