Genus på menyn : Analyser av stabila kol- och kväveisotoper på skelettmaterial från Bjärbygravfältet från äldre romersk järnålder i Kastlösa på Öland
This paper deals with diet and gender in the early roman iron age in Sweden. Human bone and tooth material from the Iron Age cemetery at Bjärby in Kastlösa parish on the island of Öland have been analysed for stable carbon and nitrogen isotopes. 21 individuals were sampled. Where possible 4 samples were taken from each individual, from the first, second and third molar respectively and from one compact bone. By doing so it is possible, at least in theory, to trace intra-individual diets throughout life.
På väg mot ett mer hälsosamt samhälle? : En kvalitativ studie över hur kvinnor mellan 17-65 år blir påverkade av massmedias hälsorapportering
Bakgrund: Vi lever idag i ett informationssamhälle där vi ständigt matas med ny kunskap och olika valmöjligheter. Ett område som har fått ökad plats på massmedias agenda på senare tid är hälsa och livsstil och dagligen exponeras vi människor av budskap över hur vi kan förbättra vår hälsa och ändra våra levnadsvanor.Syfte: Syftet med vår studie var att undersöka om en utvald grupp kvinnor mellan 17-65 år blir påverkade av massmedias hälsorapportering och de hälsobudskap de möter. Vi syftade även till att undersöka hur denna eventuella påverkan yttrar sig samt klargöra vilka eventuella skillnader det finns i påverkan mellan olika åldrar.Metod: För att få svar på våra frågor genomförde vi en kvalitativ studie med samtalsintervjuer som datainsamlingsmetod. Vi intervjuade 6 kvinnor i åldern 17-65 för att ta reda på deras upplevelser och tankar kring problemområdet.Slutsats: Resultatet av undersökningen visade att vår utvalda grupp kvinnor blir påverkade av massmedias hälsorapportering. Resultatet visade även att åldern har betydelse när det gäller hur och i vilken grad respondenterna blir påverkade av hälsobudskapen.
Etnocid i Kosovo ? språk och kultur som vapen i en etno-politisk konflikt
The aim of this master's thesis is to describe the role of language and culture as ethnical identification factors and illustrate how these have been used as political weapons by the Serb regime in Kosovo during the last decade. The thesis discusses the concept of ethnicity, the relations between the politics of identity, nationalism, ethnic mobilization and the importance of language and culture. Kosovo has historically been characterized by severe ethnic antagonism between Serbs and Albanians. Different languages, cultures and religions beside political processes led to ethnic cleavages that paved the way for ethnocentrism, ethnonationalism, chauvinism, ethnic cleansing and civil war. Since 1989, the Serbian authorities have intervened in all important spheres of life, in an attempt to Serbianize Kosovo.
Slaget om Breitenfeld : En analys med hjälp av de grundläggande förmågorna, marktaktiska grundprinciperna och ledningsfilosofin uppdragstaktik
The Battle of Breitenfeld took place in 1631, during the 30-year war. It was the biggest battle the Swedish army has participated in. The essay analyses the battle from a Swedish-Saxon perspective, using the basic skills, ground tactical principles and management philosophy of decentralized command.The essay is based on a case study stemming from a qualitative text analysis, and is as such divided into three parts. The first part of the essay describes my theory, and explains what the different terms stand for. The second part narrates the battle and the participating armies.
Oxygen Health : Inlösning av syre i vatten
The project has been provided by Zenit design group and the goal for this project was tomanufacture and perform tests of a prototype that supersaturates water in a continuous flow ofwater. The project has involved finding and sorting out relevant data in scientific papers, books,communication with foreign manufactures and other platforms for information.The project has resulted in manufacturing of a test rig and an oxygen infuser based onmembrane technology. The test rigs purpose was to perform tests on oxygen infusers fordifferent comparison test and performance benchmarks in a in a laboratory provided by Zenit.The project led to satisfying results using the oxygen infuser manufactured by the authors withcomparable levels of saturation to the reference infuser.The theory behind this project is based on medical research, belonging terms will be explainedbut the authors have chosen to delimit the project from the medical area. The reason for this islack of knowledge in this area and its irrelevance to the mechanical engineering education insuch..
Förekomsten av den genetiska varianten laktapersistens hos neolitiska grupper från Öland : The contribution of the genetic variant Lactase persistence among Neolithic people from the Baltic island Öland in Sweden
This study deals with the contribution of the genetic variant lactase persistence among Neolithic people from the Baltic Island Öland. Skeletal remains from twelve individuals went through DNA sequencing in order to find the mutation that allows adult individuals to digest milk sugar. The twelve individuals were chosen from two different Neolithic sites, where the archaeological and isotopic data suggest that the individuals from Köpingsvik were hunters and gatherers and the individuals from Resmo were early farmers. The individuals with the genetic variant lactase persistence can be described with selection and genetic flow. Only five individuals produced results and the mutation was found in two of the subjects. All the individuals who were successfully sequenced came from Resmo, whereasno individuals from Köpingsvik yielded any results.
Påverkansfaktorer i relation till viktminskning bland gymnasieungdomar
Syftet med studien var att undersöka om de gymnasieelever i årskurs 3 som uppgav att de försökte minska sin vikt hade ett högre Body Mass Index (BMI) än de som inte försökte minska sin vikt, samt undersöka vilka faktorer som påverkade gymnasieelevernas vilja att gå ned i vikt? Författarna använde en survey-metod i form av en enkätundersökning för att kunna jämföra variabler samt se orsakssamband och påverkansfaktorer. Enkäterna besvarades på den aktuella gymnasieskolan med respektive klassföreståndare närvarande. Studiens resultat baseras på tre gymnasieklasser i årskurs 3 och omfattar 52 elever, varav 35 flickor och 17 pojkar. Resultatet visade att den största andelen deltagare som ville minska sin vikt var de normalviktiga och anledningen var för att de ansåg sig själva som för tjocka.
Att stödja elevens övning : om tajmad minnestränings påverkan på inlärning och motivation i distansundervisning med yngre instrumentalister
En hel del av forskning inom kognitiv neurovetenskap tyder pa? att effektivare uppla?gg av repetitionstillfa?llen fo?rba?ttrar inla?rningsprocessen hos eleverna, eller ra?ttare sagt hos ma?nniskor i alla a?ldrar.Uppsatsen handlar om yngre instrumentalelevers inla?rningsprocess i relation till hja?rnans minnesfunktioner och underso?kningen fokuserar fiolundervisning pa? nybo?rjarniva?. Jag har utfo?rt ett empiriskt experiment av tajmade repetitionstillfa?llen via interaktiva onlinebaserade samtal med tre yngre elever.Alla de tre eleverna har under projektens ga?ng a?stadkommit fo?rba?ttringar av de fa?rdigheter som stod i fokus vid de tajmade repetitionerna. Experimentperioden har haft positiv inverkan pa? elevernas motivation, men deras uppna?dda fo?rba?ttringar bedo?mer jag vara av icke besta?ende karakta?r.
Magnetiska egenskaper hos Öje-Diabasen, Dalecarlia
A study of paleomagnetic remanence and anisotropy of magnetic
susceptibility (AMS) has been performed on the Öje-Diabase
in Dalarna, Sweden, and on basic dikes associated with the
alkaliquartzsyenite/granite Noran-pluton in central Sweden.
Based on isolation of directions of characteristic magnetization
in the basic rocks, a division into three different groups (A,B,C)
has been made. Group Aconsists of dolerites of Jotnian origin,
both dolerites from the Öje-Diabase and dikes associated with
the Noran-pluton are included in this group, making them coeval.
Group B is suspected to show a re-magnetization from the later part
of the Svekonorwegian orogeny. Group C belongs to the
Blekinge-Dalarna-Dolerites (BDD). Thermal demagnetization of
dolerites revealed two different types of demagnetization behaviours,
one where magnetite clearly was the source of the remanence, and an
other with a linear decrease in magnetization intensity. The measurements
of magnetic anisotropy reveals a magnetic fabric with an almost
horizontal foliation and a lineation that indicates a fairly uniform NNW/
S-SE flow direction of the magma..
När en roman blir teveserie: Om Jane Austens aktualisering i och med 1995 års teveinspelning av Pride and Prejudice
The aim of this Masters thesis is to examine how Jane Austens Pride and Prejudice, first published in 1813, was established in different literary orbits after the transformation to the television medium in 1995. I also want to find out what this adaptation meant for the popularity of Jane Austen, the circulation of her works and the rebirth of her authorship. It has furthermore been of interest to discuss the reasons why Jane Austen and her works became so popular. Questions posed in the study are: What has the 1995 production of Pride and Prejudice meant for the spreading of Jane Austens literary work and for the rebirth of her authorship? How has Pride and Prejudice moved between the literary orbits after it became a television-serial in 1995? Why did the circulation get the character it got in the 1990s? In order to find feasible answers to these questions I have used Hans Hertels model of the five literary orbits as theoretical starting point.
Läcksökning med penetrant ? kvalitetssäkring av
Vacuum box leak testing is, because of geometrical problems, not always possible andtherefore an alternate test method with dye penetrant is used. DEKRA Industrial has identifieda need for quality assurance of the method and development of a written procedure withguidelines that lead to more uniform ways of testing.A literature study was done to get a general overview of nondestructive testing (NDT) and tosee how the method is used in different applications. European and American standards werestudied. Analytical and numerical solutions, involving flow simulation, were deemed to berather difficult and beyond the scoop of this project. Thus the problems had to be solved byusing experimental methods.
Energieffektivisering av maskinsalsventilation : Utredning av nuläget och utvärdering av åtgärdsförslag
Stora Enso, Skoghalls bruk är en av världens största producenter av livsmedelskartong och tillverkar ca 700 000 ton per år. Pappers- och massatillverkning är en energikrävande industri och det finns stort intresse att sänka energianvändningen i olika processer. Maskinsalsventilationen på kartongmaskinen KM8 är utrustad med ett värmeåtervinningssystem som tar tillvara på överskottsenergi från pappersmaskinens torkparti. Denna energi används sedan för att förvärma tilluften till maskinalen. På grund av att styrningen och driften inte fungerar optimalt idag måste energi tillsättas från ett ångbatteri.Målet med denna studie var att utreda systemet i dagsläget i form av mass- och energibalanser för sommaren och vintern.
Överavkastande Aktierekommendationer : En utopi eller en hållbar investeringsstrategi?
Background: The value of stock recommendations have been debated for a century andthe debate has escalated since Alfred Cowles (1933) published his research in ?Can StockMarket Forecasters Forecast?? As of late, savings in stocks has increased and the householdsare managing their savings more actively. The consequence of the increased interestin stocks has resulted in a growing market for stock recommendations. Not just financialmedia but daily newspapers have embraced this new found interest, hence stock recom-mendations can be found in almost all large newspapers in Sweden. Furthermore, this phe-nomenon has also lead to intensified research within stock recommendations.
En dekonstruktion i ljud : J.O. Mallanders Extended Play
J.O. Mallander?s Extended Play (1968) is a sound recording, a readymade, of the counting of votes in two presidential elections in Finland, during 1962 and 1968. A voice repeats monotonously: ?Kekkonen, Kekkonen, Kekkonen, Kekkonen, Kekkonen?? Although the Finnish president Urho Kekkonen represents, almost personifies, the politics of the post World War II period in Finland, Extended Play does not explicitly address the political. Rather, as this essay argues, it engages in the discourses of power and politics by providing a temporalization of its fixedness, or what Jacques Derrida terms the proper.Extended Play is, in parallel with Derrida?s critique of western metaphysics, a deconstruction in sound that challenges the state ideologies conveyed in the process of the counting of votes, where the presuppositions of the presence of the voice characterizes the ambiguities of power that Kekkonen?s politics of neutrality represent.Mallander?s readymade emerges as a double of the game theory strategies of the Cold War, a mimetic surplus of the administrative control mechanisms of sound recording.
Orsaker till kolik hos häst
The aim of this work was to investigate possible risk factors for colic in horses, and to describe what horse owners can do to prevent this condition.
The gastrointestinal system of the horse is constructed for continuous high fibre consumption for a period up to eighteen hours a day. Under those conditions, the continuous flow of digesta stimulates gut motility so that the intestines move constantly. When the diet is changed rapidly and the horse is being fed high rations of concentrates each day, the risk of getting colic is higher compared to when consuming less concentrates and giving the horse a stable diet.
Lack or absence of access to water and restricted allowance to move freely every day increases the risk of colic. Changed management practices and decreased activity contributes to increased risks, as well as other critical risk factors such as breed, season and age combined with rapidly changed management.
More knowledge and education is required of the horse owners about feed requirements in the horse, management routines and rapidly changed activity..
