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%.

Elektronisk referenstjänst vid några svenska universitets- och högskolebibliotek

This is a study on the electronic reference work of some Swedish university and university college libraries. The purpose of the study has been to find out how the service works at the different libraries, to study the electronic reference interview and to find what is important when you start a new electronic reference service in the light of Brenda Dervin's sense-making theory study. Furthermore, we examine the aims of the electronic services offered and the differences between electronic and traditional reference interviews. In the background to the study we place electronic reference services in a context by describing the role of information technology and electronic mail in the libraries. The electronic reference interview is studied with the help of literature on the traditional reference interview.

Varför ryska? ? En fråga om genus? : En fallstudie om motivation till att läsa ryska

The teaching of modern foreign languages within Swedish educational system has been a subject of a number of alarming reports in recent years. Several studies have shown that students lack motivation to learn any language but English. Of particular concern is the young males? underachieving and disinterest in foreign languages. In the meantime, a number of international studies and the statistical data from Swedish national agencies of secondary and higher education (Skolverket and Högskoleverket) have indicated that Russian is one of the languages that are favoured by males. The primary goal of my case study was, therefore, to examine students? motivation to learn Russian and their attitudes towards language, community and Russian-speaking people.

Bräkanden från förr : att skilja får från getter utifrån kv. Apoteket 4-5 i Visby

To differentiate between bones from sheep (Ovis aries) and bones from of goats (Capra hircus) is a long lasting challenge for zoologists, archaeozoologists and osteologists. Especially considering archaeological remains which are often found fractured and poorly preserved due to taphonomic processes. Zeder & Pilaar?s (2010) and Zeder & Lapham?s (2010) methods of species differentiation has shown promising results when used on bones from modern sheeps and goats. This paper aims to evaluate these methods by exerting them on excavated bones from kv.

Vem har makten att besluta om jämställda läromedel?

Mixed Martial Arts (MMA) är en kampsportsgren som blandar tekniker från diverse andrakampsporter och där utövaren växlar mellan brottning, så kallad grappling (brottning medlås), samt stående kamp. Sporten har tidigare mött på hårt motstånd och diskuterats en hel delbland annat i media, men dess popularitet har växt mycket det senaste decenniet. Många somidag väljer att börja träna kampsport väljer just MMA.Syftet med uppsatsen är att undersöka vad MMA fyller för funktion för dess utövare. Fokusligger i att undersöka hur stor påverkan MMA har i utövarens liv och hur man kopplar ihopMMA med sin egen identitet. Detta gör vi genom att med MMA-utövares egna berättelserexemplifiera hur detta kan ta sig till uttryck.Studien genomfördes med en kvalitativ undersökningsmetod och det empiriska materialet harsamlats in genom totalt fyra individuella intervjuer.

Trovärdighetsbedömningen av muntliga utsagor i brottmålsprocessen

In some criminal cases, the only existing evidence is the verbal statement of a witness or the plaintiff. The typical example is an alleged rape where victim and perpetrator have had some kind of relation, and their records of the incident differ. In these cases, the assessment of the value of the evidence drawn from the plaintiff's story is of crucial importance. On the one hand, a false positive judgment means that a person is wrongly convicted, on the other hand, a failure to correctly identify a truthful claim of rape means that a victim of a severe crime is left without judicial remedy. That the prosecutor must prove that the crime is committed by the defendant without reasonable doubt, means that there is much more chance of a failure to convict guilty felons, than of the opposite.In the essay, the rules of criminal procedure directed at the evaluation of the verbal statement are identified and critically evaluated from the perspective of how they may or may not facilitate the judgment of a verbal statement presented before the court, either in person, or through other media such as video.

?Ge mig ett tält med bubbelpool och jacuzzi, då säger jag ja till friluftsliv? : en komparativ studie om friluftsundervisning

Samband på individnivå mellan akuta klövskador och cellhalten i mjölk hos mjölkkor :

The purpose of the present study was to investigate the cow-level association between acute hoof lesions and the somatic milk cell count in dairy cattle. Cows from three loose-housed Swedish dairy herds were enrolled in the study if they had an acute hoof lesion treated by a veterinarian or professional hoof trimmer during the preceding year, according to farmer records. Studied lesions were sole ulcer, dermatitis, interdigital necrobacillosis and hoof abscess, in each case causing lameness. For each hoof-diseased cow, 0 to 3 healthy cows were included, matched with respect to herd, breed, parity and lactation stage. Cell counts were obtained from monthly test recordings from one month before to three months after the hoof-lesion diagnosis, and log-transformed.

Söka eller browsa? : En undersökning om personliga mönster i sökbeteendet vid informationssökning på nätet

This Master's thesis in Library and Information Science aims to explore if personal patterns can be detected in web-searching. It is based on a study where the search sessions of nine test persons were video-recorded, transcribed into logs and analysed.A major objective was to find out whether there is a correlation between individual searchers' personal attributes and their web search behaviour. The logs were therefore compared with the test persons' results in a learning style test (Kolb's Learning Style Inventory) and with interview answers about information behaviour and personal background.While several patterns were indeed discovered, none of them turned out to be strictly personal. The nine test persons could be divided into five types of searchers: the purely analytic searcher; the generally analytic searcher; the balanced searcher; the mixed searcher and the browser. All types of searchers were found to have the attribute learning style in common.

Cancersjuka patienters upplevelse av livskvalitet och välbefinnande i samband med yogautövning. : En deskriptiv kvalitativ studie med semistrukturerade intervjuer.

AbstractAim: The aim of this study was to describe cancer patients? experiences of quality of life and wellbeing in relation to yoga practice.Method: A descriptive qualitative study with semi structured interviews was carried out during the fall of 2009 at the University of Uppsala. Informants in the study were cancer patients who were participating in the yoga/psychotherapy group at the clinic of oncology at the Akademiska hospital in Uppsala.Result: Five out of six informants experienced that their quality of life and their wellbeing improved by practicing yoga. One informant had mixed feelings which were not due to the yoga practicing, but to the place where it was practiced. For her this place was associated with illness.

Den förvrängda invandraren : En kvalitativ studie om hur publiken tolkar och genomskådar invandrarrepresentationer i svenska medier

The aim of this study was to seek knowledge about how the media audience interprets media representations of immigrants as well as the construction of ?us? and ?them? that is created from the media report.We implemented two focus group interviews, one containing only ethnical Swedes and one holding a variety of people with different ethnical backgrounds. The focus groups got to read nine news articles from different Swedish news papers selected by us, based upon previous research. These articles got to serve as the basis of the discussion.To supplement the focus groups, which got to represent the media audience, we also interviewed two different persons we choose to call informants, whom are both immigrants and are or have been politically active and often appear in local media.The interviews were our empirical material which was used for analysis. The method we used was qualitative analysis of meaning and was based upon a hermeneutic starting point, meaning that all humans are interpreting beings.

Äldres personers upplevelser av ensamhet : En litteraturstudie

Bakgrund: Åldrandet innebär naturliga biologiska, sociala och psykologiska förändringar, andelen äldre i samhället beräknas öka och äldre upplever ett lägre socialt deltagande kontra resten av befolkningen. Ensamhet beskrivs som en obehaglig eller oacceptabel avsaknad av relationer och involverar hur en person uppfattar, upplever och utvärderar den avsaknaden. Hälsoproblem och upplevelsen av livskvalitet är knutet till ensamhet. Ingen konsensus om fenomenet ensamhet finns inom vårdvetenskapen. Sjuksköterskan har viktig roll att upptäcka, motverka och förebygga ensamheten, därför behövs mer kunskap om fenomenet.

Vallfoder till slaktgrisar : effekter på tillväxt och social beteende vid utfodring

The aims with the project were to investigate how forage consumption affect production and pigs behaviour around the feeding. This degree project was designed to follow 48 growing/finishing Hampshire*Yorkshire pigs, from 30-110 kg live weight, fed diets with or without 20 % forage inclusion. The pigs were divided in three groups due to dietary treatment. In the first group the pigs were fed 20 % of the energy in the feed ration by long grass/clover silage (LE) and the remaining 80 % by a cereal concentrate. Group two was fed chopped grass/clover silage mixed with cereal concentrate (HE) in the same amounts as LE.
