Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

IT-kompetens - utveckling av ett mätinstrument

Problem: In society of today corporate competence is an important factor for survivor and development. IT is developing rapidly and can not be ignored by companies.

To determine the IT competence within an organisation, this competence has to be measurable.

Levande Skogsbruk : om problem i ett naturvårdsärende

In this study, some aspects of communication that are creating problems in a chosen forest conservation case are explored. Focus is on how the manager of a forest experience how he is treated during a formal decision of conservation. The paper also gives introduction to communication theory as well as to present forest policies in Sweden. Explanations of the most common concepts and terms in forest conservation is presented and such a understanding is necessary if the reader is to acquire enlightment from the material and the following discussion. This paper focus on a conflict between the county administrative board, a Swedish regional authority, and a private forest-manager. This is a case where the manager feels that the authority is forcing a sale of land, because the forest is being turned into a conservation area. The problems are not just economical, the manager feels mistreated and left out of the discussion, and the negotiation is long and problematic as shown in the interview and the case study. In the study, an in-depth interview is made with the manager of the forest, and a case study has been made based on the documents in the case attained from the county administrative board.

Liv i d?d ved: En unders?kning av f?rh?llningss?tt till d?d ved p? ?ppeltr?d i tr?dg?rdshandb?cker och bland yrkesverksamma tr?dbesk?rare

In this essay, several factors in apple tree care (specifically in relation to whether dead wood should be kept or removed) are highlighted for example, aesthetics and biodiversity. To present some background, the essay begins by introducing some previous literature on dead wood. This leads into how dead wood is treated within forestry. Next, previous research on dead wood in fruit trees is mentioned. Cultural and historical management methods are also highlighted.

Den ensamma flatan och glitterbögen : En kvalitativ studie av hbtq-personers porträttering i tre olika kvinnomagasin

The aim of this studie centers on how lgbt (lesbian, gay, bisexual, transgender) are portrayed in women?s magazines. The magazines we have chosen to analyze are FRIDA, VeckoRevyn and amelia, which all three have different target groups. We have, with the assistance of the rhetorical and semiotic analysis methods, assessed 18 articles with their associated photographs. These methods are part of the qualitative analysis model and are used in order to study less empirical data with more depth.

Välfärd - ett begrepp i förändring : En diskursanalys av LSS

In this thesis, the results of a survey regarding grade progression between secondary and upper secondary school in a municipality in the north of Sweden serve as the starting point for a study of the experiences and expectations of a number of 16 year old girls who are in the first year of upper secondary school. The study is performed by means of focus group interviews with female pupils from the three largest upper secondary schools in said municipality in an attempt to gauge their experiences of grades, grade assessment, teacher practices and perceived differences in how boys and girls are treated. The results show that most of the girls are disappointed with upper secondary school so far. Many of them feel that secondary school was both more fun and more rewarding in a sense of learning. Their appreciation of how this more rewarding atmosphere affected their grades differed between the various groups.

Vad innebär EU-Battle Groups insatstid för dess transporter?

Sverige har med sina åtaganden inom EU Battle Groups tagit ansvar för en militär verksamhet som kräver storamått av rörlighet med snabb insatstid. Troliga konflikthärdar kommer inom en överskådlig tid att uppstå långtifrån Skandinaven vilket kräver planering och snabba transporter med stor kapacitet samt lång räckvidd. Enallvarlig kapacitetsbrist i en svensk Battle Group utgörs av bristen på nationella resurser för strategiskatransporter. Avsaknaden av egna militära strategiska transportresurser gör att behovet av civila aktörer och nyagemensamma samverkansformer inom kommunikationstjänsten aktualiseras.Uppsatsens syfte är att analysera hur EU Battle Groups insatstid påverkar transporterna och desstransportförberedelser.Metodmässigt bygger uppsatsen på ett antal frågeställningar vars svar söks genom litteraturstudier ochkvalitativa intervjuer. Den teoriansats som ligger till grund för denna uppsats är systemteorin vilken i sin turhar kompletterats med System Dynamics och dess systemformalisering av materielflöden.Resultat visar på att EU BG med nuvarande resurser inte kan hålla uppsatta tidskrav men med bättreförberedelser kan transporterna påskyndas.

"You call this archaeology" - om uppfattning och fördomar av det arkeologiska yrket med film som ingångspunkt

In my essay I will study the injustice within science in movies, in this particular case: Archaeology. This essay will also examine whether there is reason to believe that there is aconnection between this unfairness and what's being displayed of the archaeologist in popular culture. In my case I have decided to focus on the movie industry because it's a dominant part of our daily life. I have chosen to explore two different groups of students studying an occupation. One is, of course, the archaeological institution at Lund University, and the other is a high school (upper secondary school) program called ?Omvårdnadsprogrammet? at Rönnens in Malmö.

Mångkulturbegreppet i svensk politisk diskurs

This study examines the connection between social capital and urban and rural areas. The study divides the environments into two categories; metropolises and rural areas. Metropolises are defined as any of Swedens largest cities Stockholm, Gothenburg or Malmö. The study also examines if there is a difference between these groups in how high social trust they have to people living in the same areas as themselves versus people who live in other areas. The studie also focuses on the urbanization that the world is going through, where people move from rural areas into the cities for work and education.

Sverigedemokraternasanvändning av begreppet?svenskfientlighet? : en diskursanalys

The Sweden Democrats uses a term to describe a situation where ?swedes? are being discriminated against by other ethnic groups and where the elite is promoting this. The term ?svenskfientlighet? can be translated as ?swedofobia? and in this thesis a speech by the party leader Jimmie Åkesson held during the election campaign that solely was dedicated to this term is being analyzed with the help of tools developed by the scholar Ruth Wodak. Ruth Wodak has previously analyzed the rhetoric by other European right-wing-populist parties like FPÖ in Austria and has asked for other researchers to analyze the speech used by right-wing-populist and extremist parties to get a better understanding for just how these parties construct their different enemies.

Brunbjörnens (Ursus arctos) inverkan på den nya svenska älgförvaltningen

The European Brown bear (Ursus arctos) has gone from basically being extinct in Sweden to, 2008 being estimated to a total of 3298 individuals. When looking at the new Swedish moose management system it is important to have an ecosystem-based approach and therefore include all the parts that moose impacts on and from in the management, especially the brown bear. Primarily in the spring and early summer the brown bear is a significant predator on moose calfs which must be taken into account in moose management. When the bear recolonize areas that it has previously been eradicated from, it will once again come in contact with people who are not accustomed to the bear's role in the ecosystem. We studied three groups of moose management areas with different predation by bears.

Tillämpningar i kemiundervisningen : en studie av strategier för att presentera och synliggöra tillämpningar

The aim of this study is to investigate how and in which form students come in contact with practical applications in the upper secondary school course Chemistry B. The study is based upon the assumption that all learning is situated in a social environment. The theoretical framework is the design theory perspective, which entails an assumption that the pedagogical tools affect the knowledge content.The empiric materials in the study are collected through three methods: textbook analysis, classroom observations and questionnaires. Two groups of students and their teachers were observed during a section of the relevant course. The textbook analysis focuses upon the same course section in the textbooks of the two groups and compares these books with the relevant section in a third textbook.
