Införande av mjuka golv för mjölkkor : en fallstudie

Soft rubber flooring have gained in popularity over the last years. Rubber flooring al-lows cow to move more freely without slipping and improves claw and leg health. The purpose of this study was to investigate the influence of a stepwise introduktion of soft flooring on cow`s placement in cow houses with robotic milking. A case study was carried out in a herd in northern Sweden with 41 cows. Observations were made every 15 minutes between 09.00 and 16.00 concering cow placement in cu-bicles, in cubicle alley, in feeding alley and in feeding alley with the head through feed-ing gate. One observation period was carried out per flooring alternativ: 1) all concrete slatted floor, 2) rubber slatted floor in feeding alley and concrete slatted floor in cubicle alley and 3) rubber slatted floors in feeding alley and solid rubber floors in cubicle alley. The study showed that 6 %-units fewer cows lay in the cubicles when the feeding alley surface was slatted rubber.

Risk Management for commodity consumers -A study of the Airline industry-

The aim of this study is two folded. We wish to investigate if there is a value premium from hedging jet fuel exposure for American and European airlines. We also seek to answer if airlines can affect their probability to default by using Risk Management. During the period 2003 ? 2006 there existed a value premium for airlines that hedged their expected future consumption of jet fuel.

Från misstanke till dom : En analys av Aftonbladets och Expressens skildringar av Anna Lindhs mördare

The Swedish foreign minister Anna Lindh was murdered on September 10 2003. The police pursuit for the man that murdered her was initiated immediately. Two weeks later, the police arrested the 24-year-old man that six month later would be sentenced to imprisonment for life for the murder of Anna Lindh. The main purpose of this essay is to examine how the man that murdered Anna Lindh was described in Aftonbladet and Expressen from the time of his arrest to the sentence of guilty. One part of the purpose of this essay is also to inquire how the Swedish evening press paid regard to the ethical publicity rules in their descriptions.

Hjärtfrekvensens förändring vid sinläggning av undervisningskor vid institutionen för kliniska vetenskaper :

It?s been noted that cows held at the section of ruminant medicine and epidemiology, Swedish University of Agricultural Sciences (IME), used for the education of veterinary students, have a lower heart rate than what is considered normal for ruminants. In this investigation the heart rates of seven lactating cows were recorded continuously during the period around drying off. The first recording took place at the farm from where the cows were bought, and then their heart rate was monitored after their arrival at IME and further on until they were completely dried off. The results were then compared to the heart rate of seven already dried off cows from the same farm.

Försvinn. Påminn. Eller återvinn? : om det industriella kulturarvets framtid genom Norra Sorgenfri

This essay deals with the industrial past, present and future and begins with the impact and importance the industrial revolution has had on us humans, socially, economically and structurally. Today's society has developed from industrial production of goods to the production of services but the industrial sites remains. The essay examines issues concerning the protection of the industrial environment, their status as a cultural heritage, what is done with our industrial heritage and the opportunities it has for the future. Malmö has a great industrial history and now one of the cities oldest industrial sites, the north of Sorgenfri, will be transformed. The essay compares the plan with guidelines for future development from the Town Building Office with an antiquarian investigation for the same area.

Inomhusklimat och energianvändning med avseende på fönsterkonstruktion. Konsekvensstudie för glas- och solavskärmningsalternativ

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

En legitimering av läraryrket : Kan det höja statusen?

In May 2008, the Swedish Government proclaimed several proposals in order to increase the status of the teaching profession. One of the proposals was that each teacher should be obligated to obtain a "teaching license" to be allowed to teach. The license/certification will guarantee that the teacher has the sufficient knowledge of pedagogy and subject obtained from University. The existing teachers who do not hold a proper certification today will be given a certain Time period to attain one. The teachers that are certificated teachers but that are giving lessons in subjects not certificated in will be given a chance to obtain the proper knowledge of the subject.

En jämförande studie av några fritidslärares och klasslärares syn på formellt och informellt lärande

The aim of this thesis was to investigate how teachers in school and in leisure time center look at informal and formal learning. Informal learning is often associated with leisure-time while formal learning is generally linked to school. My questions also deal with the teachers? view of each other?s activities from a learning perspective and visibility of informal learning. I have made an empirical study with qualitative, semi-structured interviews with three class teachers and three leisure teachers.

Informatörer och professionalisering

The foundation for this thesis lies in whether or not, and how, the body representation in printed commercials, specific products directed to the body (shampoo, body lotion etc.), has changed during the last fifty years. Four years have been chosen because of the changes in society that we believe might have had an impact. The commercials that have been picked out are the ones that best represent the general view of the body. We have found that the changes when it comes to body presentation has followed the social development to a certain degree, but it is difficult to say how much the society has had an affect on the body ideal in advertising. Representations of the male body is something that has escalated since the early 70?s, fifteen years earlier few commercials was made with male models, and the few there were, never showed more than the face.

Effekter av urbanisering på grönalgen trädgröna i Linköpings stad med omnejd. : Biologiundervisning i närmiljön

Urbanization has for a long time been a threat to our biodiversity. Epiphytic organisms such as lichens have been negative affected by traffic pollution and the new urban environment surrounding their old habitat (van Her 2001). Another epiphytic organism is the green algae Desmococcus olivaceus. Unlike lichens the green algae is favoured by polluted areas. The aim of this study was to investigate if time in urban environments affected the cover of the green algae on old oaks.

Användande av avskjutningsstatistik i förvaltning : påverkar tidigare jakt CPUE?

In fisheries, there is a long tradition to use catch data when evaluating changes in the stock and effects from harvesting. It is a common practice to use Catch Per Unit Effort (CPUE) as an index of population size, and several studies have investigated the properties of CPUE in relation to population abundance, spatial distribution and efficiency of gear. In research, catch rate on trap-transects is used as an index of abundance for wildlife species but CPUE is rarely applied as a tool in harvest management.In 1993, more than 60 000 km2 of the state managed mountain range in Sweden was opened to the public for small game hunting, under the responsibility of the county administrative boards in Jämtland, Västerbotten and Norrbotten. The total area is now divided into 332 hunting units (median=73 km2) and an internet based system is used to administer licences and reporting bag statistic. Each hunter has to register the results within two weeks after the hunt.

Vad kostar deltid? Kvinnors deltidsarbete ur ett pensionsperspektiv

Mothers of small children often work part-time in Sweden. Since old age pensions are based on lifetime income, part-time work leads to lower pensions, as long as there is no compensation from non-actuarial benefits such as minimum pensions. In this paper, I investigate whether different components of the Swedish pension system provide incentives for part-time work among women. The analysis is performed through a simulation of future pensions for 9 typical women in a certain cohort. For three levels of education, I compare pensions of women with different labor market participation rates in different growth scenarios.
