En smak av svensk manlighet : Ideal och värden i sportdrycksreklam
The society of consumption exposes us to a lot of information, where advertisement constitutes an extensive part. Due to its expanding, advertisement receives a natural and obvious space in our everyday life. This study aims to investigate how social and cultural values can be mediated in advertisement. The focus has been put to ideas related to health and fitness in the advertisement of power drinks. The thesis takes social constructionism as a starting point, and combines image- and critical discourse analysis in purpose to analyze the pictures.Sociology of consumption, construction of identity, lifestyle and everyday life all constitute an essential part of my analysis.
Den osynliggjorda kvinnan : En analys av läromedel i religionskunskap för gymnasiet
This thesis has the purpose that through a text analysis examine how four schoolbooks for high school treats the religions Judaism and Hinduism. The schoolbooks are from the years 2000, 2001, 2003 and 2009. The perspectives are from a religious viewing point, that means that the women are religious, Jewish feminists and Hindu feminists. The theories used are written by these women and are academic litterature. The questions are how are women represented in the schoolbooks, is the feminist critique present or are the two religions represented and described in an invariable way, and is the description of Judaism and Hinduism consistent with the curriculum?The text analysis used in this examination means that reality is organized through and by the language used by the actors in that reality.
Rening av avloppsvatten med anaerob membranbioreaktor och omvänd osmos
This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.
Famas och Frenchs två faktorer: proxyvariabler för konkursrisk?
The aim of this study is to examine whether the two factors SMB and HML in the Fama-French Three Factor Model proxy for default risk. The study is based on companies noted on the Stockholm Stock Exchange between 2003 and 2008. These companies are used to create the factors SMB and HML, as well as a default risk factor we call RMS. In a first set of regressions, we examine the explanatory power of the original Fama-French model on a set of portfolios consisting of Swedish companies of different size and book-to-market ratio. The default risk factor RMS is then added to the original Fama-French model.
Kryptosporidieinfektion hos nötkreatur : utvärdering av en ny metod för påvisande av subklinisk infektion
Cryptosporidium parvum is a protozoan parasite causing diarrhoea in many different animal species including cattle and man. It is an important enteric pathogen in neonatal calves and it is the second most common pathogen found in diarrhoeic calves in Sweden. Subclinically infected adult cattle have, in international studies, been shown to shed a low number of oocysts in faeces and this has been recognised as a potential source of infection for new-born calves. The detection methods used for diagnostic purposes are based on microscopic investigation of faecal smears. These methods have a fairly low sensitivity and samples from subclinically infected cattle have to be concentrated before analysis.
Konstruktion av patientsimulator för anestesimaskiner
A patient simulator for testing anaesthesia machines has been developed at Maquet Critical Care AB, to reduce costly and time-consuming experiments on animals. The device simulates human lungs regarding lung dynamics and volume, uptake of anaesthetic agents and the production of carbon dioxide, heat and moisture. Further demands on the simulator are durability and size; the device shall be compact enough to be moveable.The resulting simulator fulfils the requirements and enables better repeatability and ability to test extreme cases than experiments on animals do.Uptake of the anaesthetic agent is achieved in a active carbon filter and controlled by regulating the flow. The flow is created by a regenerative blower and controlled using a proportional valve. The uptake can be set by the user or by a simple uptake model modified to recursively handle changes in the concentration of anaesthetic agent.Carbon dioxide is fed into the system from a tank by a mass flow regulator.
Rötning av matavfall ? en studie av metanutbytet hos matavfall förbehandlat med skruvkrossteknik samt vid samrötning med bioslam från pappersbruk
Today's society is facing major challenges. In order to reduce the climate impact fossil fuels should be replaced with fuels that do not contribute to the greenhouse effect. The growing population generates organic waste originating from industry and households so called organic fraction of municipal solid waste (OFMSW). Through anaerobic digestion, waste can be utilized to produce energy-rich methane gas. In this way, waste can be a resource instead of a burden on society.
?Att d? som en tjej? - Genusperspektiv p? p?visandet av makt och maktrelationer utifr?n begravningspraxis inom j?rn?ldersarkeologi
This thesis explores the role of gender perspectives in understanding power and power relations in Iron Age burial practices, focusing on two high-status female graves: Grave X from Tuna in Badelunda (Sweden) and the Vix burial (France). Through a comparative analysis of burial contexts, artefacts, and interpretations, the study examines how androcentric frameworks and contemporary gender norms have influenced archaeological discourse. Employing theories of gender, queer studies, and standpoint feminism, the research highlights the limitations of binary gender categorization and advocates for intersectional approaches. The findings challenge traditional stereotypes of passive female roles, emphasizing instead the active agency and complexity of women?s social identities in prehistoric societies..
Aspirantutbildningsprogram
Because of the currently large recruitment needs within the Swedish nuclear powerindustry, it is necessary to recruit trainers from other recruitment groups than that ofexperienced operators at nuclear power plants. The foundation for a trainingprogram regarding these recruitment groups, here called ?aspirants?, has in this thesisbeen prepared. It contains a suggestion for main topics in the program. It also includesdiscussion on the balance between forms of education and a concrete example ofhow a lesson could be performed.These suggestions has been developed through analysis of interviews and surveyresponses from student groups most suited for the propositioned trainee program,and individuals with service as a trainer or closely linked to training activities withinthe industry.The analysis suggests that the candidates gets, besides the opportunity to practice asoperating staff before the theoretical training begins, a training program, tightly boundto the power plant with multiple instances of practice and the chance of going intothe power plant and see how things that are being raised in theory, look in real life.The practice, in addition to helping to create an understanding of the plant, it will facilitate networking with the operations staff to build a relationship and trust.Candidates should have plenty of opportunity to educate and see both other aspirantsand experienced trainers train.
Avskiljning av ammoniumkväve och fosfatfosfor i reaktiva filtermaterial : skak- och kolonnförsök
In Sweden more than 400 000 private households have not yet sufficient wastewater purification. These effluent is considered as an increasing problem and many onsite purification methods have been studied. In this investigation, the method of reactive bed filters have been tested by column and batch experiments. Five different kinds of filter materials with reactive surfaces have been studied concerning their capacity to absorb ammonium and phosphorus from wastewater. The materials that were examined are Filtra N, wollastonite Filtra P, blast furnace slag and Polonite®.
Styrketillväxt med hjälp av vibrationsplatta
Abstract 1.The purpose of this study was to investigate the effects whole body vibrations on maximal strength, power output and neuromuscular activity in m. pectoralis major during bench press.Participants consisted of 35 male and 9 female military high school students (m=23, 1 years). On the basis of initial maximal performances in bench press the participants was divided into two experiments groups and one control group. Intervention groups performed a specifically designed push up program on a vibrating plate respectively a step board during 12 weeks Initial load at 60 % of 1 RM showed an average of 46, 5 kg. All groups showed an average increase of 13 kg for each person after 12 weeks.
Diskursen kring misshandel : En studie av Aftonbladets framställning av förövare och offer i misshandelsfall.
The aim of this study was to examine the existing discourse of assault in Aftonbladet from the years 2012 and 2013. We have studied news articles and analysed them by using discourse analysis as theory and method.The study shows that the portrayal of perpetrators and victims in assault cases tend to differ depending on gender. The women is portrayed as weak and part of a homogeneous group while the man is portrayed as dominant and offered a more individual role. The study also shows that the normative group is separated from the deviate groups in society. The analyze show that media, through this representation, maintains the normative power in society.
"Så att få ungarna att förstå att dom är guld, det tycker jag är, det är våran uppgift" : En kvalitativ studie av relationerna mellan ungdomar och behandlare på behandlingskollektivet Hassela i Klintehamn, Gotland.
The purpose of my study was to see what kind of relationships there were between the youth and the social workers in the treatment home Hassela in Klintehamn, Gotland. The social workers work for six weeks day and night by living together with the youth. I also wanted to examine what happens when there were conflicts between them as signs of tensions in the relationships. In addition to this I wanted to study the relations between power and influence in their relationships where Hassela strives for democracy. My questions were the following; How do the youth and the staff describe the relationships between them? How do conflicts work between them at Hassela? What does the relationship between power and influence look like?The study is based on qualitative interviews with four clients and four social workers.
Utvärdering av ett Bränslecellsdrivet Flygplan.
With the increases in fuel costs due to the depletion of the world oil reserves and the increase of greenhouse gasses as a consequence to using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as well as trace amounts of other emissions. Both Boeing (1) and Politecnico di Torino (2) have shown that it is possible to build an all-electric aircraft powered by fuel cells. Both flights used small, two-seater aircraft and a constant between them was the loss of the co-pilot seat due to weight and lack of space. As this paper will deal with a commercial aircraft a primary concern is the cargo and passenger capacity and whatever impact switching propulsion system has on these.
Historiska berättelser ? en användbar undervisningsmetod?
Undersökningen gick ut på att undersöka om historiska berättelser är en relevant undervisningsmetod för att öka elevers historiemedvetande och fördjupa deras kunskaper. Kunskaper ansågs i detta fall vara fördjupad förståelse och empati samt faktakunskaper. Även elevers och lärares syn på undervisningsmetoden undersöktes. Undersökning skedde på en mindre skola i nordvästra Skåne i två niondeklasser. En berättelse och en Power Point konstruerades och den ena klassen fick lyssna till berättelsen och den andra till Power Point undervisning.
