Sweden's drinking water quality is considered to be high partly due to a high quality of the raw water and a well developed sewage infrastructure. Despite this, there is water contamination that could be prevented by installation of a sophisticated early warning system. Some of the major players in the production of drinking water have already invested in different types of early warning systems to ensure drinking water of high quality. There are various forms of early warning systems where automatic monitoring of E. Coli is an interesting alternative.

Laser for material processing possesses a number of advantages which mean that it has been and will be an important component for a wide range of industries' future development. Cutting materials processing is the dominant use of laser technology and has revolutionized the manufacturing industry. The aim of this thesis is to describe the principles of metal cutting by laser, how laser cutting is applied in practice and to identify how Swedish companies are using laser cutting. For the theoretical and technical description of laser cutting literature studies are the primary source of information. The empirical basis for the mapping of the Swedish industry for laser cutting is grounded on a survey; this includes Swedish companies that use laser cutting in their production.

Honey is a product that may contain pesticide residues due to contamination from bees pollinating various plants as well as elimination of vermin inside the hive. Different methods are needed for analysis of pesticides, since the term includes a wide range of different substances. National Food Administration lacks a validated method for determination and quantification of pesticides in honey using liquid chromatography tandem mass spectrometry, LC-MS/MS. The technique is especially important in analysis of polar and non-volatile pesticides, where gas chromatography is not functioning optimally. After investigating what pesticides could be found in honey produced in Sweden, a number of four pesticides suitable for analysis with LC-MS/MS was compiled; boscalid, impidacloprid, tau-fluvalinate and thiacloprid.

Today there are many students with behavioral and developmental disorders in schools. One of these disorders is ADHD. The medical designation ADHD stands for Attention Deficit Hyperactivity Disorder. I have chosen to research how two students with ADHD can be included in a fifth grade classroom.This research paper addresses the issues surrounding the student?s day-to-day life with a focus on the classroom.

Syftet med studien är att undersöka på vilket sätt sångpedagoger i kommunala kultur- och musikskolor upplever att de arbetar med folklig sång, samt hur de ser på ämnet vad gäller sångsätt och material. Till studien har data samlats in genom telefonintervjuer med tretton sångpedagoger, verksamma vid åtta kultur- och musikskolor i geografiskt spridda kommuner i Sverige. Intervjuformen var strukturerad kvalitativ intervju med öppna följdfrågor. Materialet har sedan analyserats utifrån ett sociokulturellt perspektiv. Resultatet visar att endast ett fåtal av informanterna anser att folklig sång förekommer i deras undervisning. De som inte undervisar i folklig sång anger svagt elevintresse och brist på egna kunskaper i folklig sång som skäl.

Stretching används dagligen efter fysisk aktivitet av allt från motionärer till elitidrottare i syfte att öka muskellängden eller minska träningsvärk. Stretching kan utföras med flera olika tekniker, en avslappnad muskel kan genom stretching förlängas upp till 130 % av sin ?normala? längd i viloläge. Det finns ett flertal olika teorier kring vad som händer med muskeln vid stretching, både sensoriska och mekaniska teorier där man tror att det sker en förändring av perceptionen, toleransen eller i muskelns komponenter. Mycket forskning är gjord inom området, men huruvida muskeln förlängs eller ej framgår inte i litteraturen, samt vilka stretchingen faktiska effekter är.

The daily newspaper market in Sweden has been a mighty strong media market, except for major market crisis which occurred in the 1990s in Sweden, that led to several newspapers came into an economic crisis. One of the actions that many Swedish newspapers did was to reduce the physical size of the newspaper from broadsheet to tabloid. After studying several academical studies from scientists and students who claim and show in their results that the tabloid tendencies has spread out in the editorial content I discovered that the common thing for these studies where firstly, that there were not many studies that showed the tabloid tendencies of the editorial content in a longer historical perspective, secondly that the studies jointly studied tabloidization tendencies (how the editorial content changed from writing about hard news to write about soft news) in the editorial content of newspapers that have changed the physical format size. The material that was analysed was tabloid tendencies in news articles in two daily Swedish newspapers, Jönköping-Posten (broadsheet) and Aftonbladet (tabloid) in the years 50s, 60s, 70s, 80s and 90s. The goal was to see if or how much of the editorial content of news articles that changed over time by tabloid tendencies in individual daily newspaper as well as a comparison of the various newspaper formats.This lead to the purpose of this master study:To investigate if it exists tabloid tendencies in the editorial content of news articles in the Swedish newspapers Aftonbladet and Jönköping-Posten between the 1950s to 1990s.In addition this purpose was operationalized from theories of tabloidization, the main theories that are used in this master study is developed by the researchers Shelly McLachlan and Peter Golding and their definition for tabloidization range, form and style.The best tool to analyse the material that have been gathered was to use of quantitative content analysis.

Elever i musikklasser med ko?rinriktning i grundskolan inga?r i en lokalt situerad musikkultur som a?r formad av traditioner med ro?tter i fo?rra seklets fo?rsta ha?lft. I denna tradition har konventioner om sa?ng med barn utvecklats. Undervisning i musikklasser sker i stora grupper men den enskilda eleven internaliserar kunskapen om att sjunga individuellt.

As companies worldwide are in search of competitiveness and larger shares of the market, organizational change has become a key-factor to sustain a competitive edge. But as organizations consist of people, the human aspect of change is not to be disregarded. When change occurs, humans need time to find their new role in the organization, a process that takes time. In this thesis the authors ask themselves what an implementation process of a new managerial role looks like. To answer this question they?ve studied LRF Konsult.

This paper intends to examine how parents think and reflect on gender issues when they borrow books for their children at the library. The theory applied is Yvonne Hirdman?s theory of a gender system. A questionnaire was made available at the Children's department of Uppsala City Library in February, 2010. The material was compiled and analyzed with the intention to try to detect trends, patterns and themes, rather than statistics and hard data.Parents in the study perceive themselves as gender-conscious.

Are agency and responsibility solely ascribable to humans? The advent of artificial intelligence (AI), including the development of so-called ?affective computing,? appears to be chipping away at the traditional building blocks of moral agency and responsibility. Spurred by the realization that fully autonomous, self-aware, even rational and emotionally-intelligent computer systems may emerge in the future, professionals in engineering and computer science have historically been the most vocal to warn of the ways in which such systems may alter our understanding of computer ethics. Despite the increasing attention of many philosophers and ethicists to the development of AI, there continues to exist a fair amount of conceptual muddiness on the conditions for assigning agency and responsibility to such systems, from both an ethical and a legal perspective. Moral and legal philosophies may overlap to a high degree, but are neither interchangeable nor identical.

Detta examensarbete har utförts på uppdrag av Vidsel Test Range (VTR) som är en del av Försvarets Materielverk.På Vidsel Test Range testas och verifieras bl.a. jakt-, attack- och luftvärnsrobotar.Ett sätt som används för att simulera ett verkligt mål är att flyga ett obemannat fjärrstyrt flygplan, kallat målrobot. Från målroboten vinschas ett mål ut, kallat släpmål. Skott sker sedan mot släpmålet. Största anledningen till att använda sig av ett släpmål istället för att skjuta på målroboten är att kostnaden blir mindre.Projektets syfte var att återuppta utvecklingsarbetet av ett nytt släpmål baserat på en tidigare tillverkad del av höljet på släpmålet.

When visiting Scaniaparken in Malmö you have the possibility of listening to music streaming out of grass-covered hills. In Helsingborg children can compose their own music and play for their friends on the playground. On a square in Nacka Strand you can hear birds singing in the quiet intervals of traf?c. What the places have in common are that they all contain sound installations.

The purpose of this study is to determine whether or not there has been a change in the use of democratic values in textbooks in social science for classes 4-6. The focus lies on democratic values from two different theoretical perspectives, Dahl?s theory of democracy and Habermas deliberative democracy. The method used is a text analysis based on a model made by Lennart Hellspong. The material we?ve analysed consists of four textbooks in social science from different decades, with a range from 1981 until today.

The City Library has a problem getting children interested in reading. Futhermore, there are no clear signs to aid children to navigate themselves to books targeted to their age group. To solve this problem, this thesis aims to design signs that is both illustrative and informative.Of the images that were tested during the research, I would assume that children in such a wide age range requires the simplest level of abstraction from testing the three testing icons, since the second level of abstraction was not interesting enough for the kids. The third, nearphotorealistic level was most liked by the children who were in the city library more often and looked for books themselves..
