Brunstvisningsförmåga hos mjölkkor- en beteendenstudie
Oestrus in dairy cattle has changed over the last decades; the intensity of oestrus has declined and the duration decreased. Several studies have shown that not all dairy cows stand to be mounted, and that oestrus expression in many cases may be characterized by other behaviours. The aim of this study was to investigate oestrus behaviour in a herd of todays? high producing dairy cattle. The study was carried out at Jälla naturbruksgymnasium in Uppsala during one week in January 2011.
Metodik för utmattningsberäkning av svets i vibrationsmiljö
In this work, a method was developed and evaluated for calculating the life of welds under the influence of fatigue loads from a vibration environment. Typically, a shaker table is used for testing a component against vibration loads. The shaker table creates a vibration environment that is defined in the frequency domain by a power spectrum.Similarly, a virtual vibration table can be used to calculate the same type of load environment, which can then be used to calculate the expected lifetime. The benefit of this method is that it can be used in design, as well as in simulation of tests before physical verification tests are carried out.Today there are methods for calculating fatigue life of non-welded base material, but since many components contain welded joints, there is a need to apply this method to those types as well. To achieve this, the thesis combines two different areas, which together provide a method for fatigue assessment of welds using a virtual shaker table.The methodology is carried out by modeling the component, and its welded joints, in a finite element program.
Parkplan för Kungälv med förutsättningar för sociala värden :
To work with environments outdoors for people, animals and plants is the main topic for the landscapearchitect.
On several occasions the work is about public places that is to be in relation with other parts of the town. It is about the activities and the life that take place.
The physical environment and the interpretation of it gives possibilities or obstructions
for people who moves around or spend time in it.Since public places, parks and places for movement are used in daily life they strongly effect the people who use the places. The concequences of this effect can be positive or negative experiences.A positive example is a passage over a brook on the way to school while a negative one is to be afraid while passing a tunnel when it is dark outside. Other examples of concequences are stress effect from traffic noice or calming environments with twitter of birds.

Att leva sitt liv: Tonårsflickor om livsangelägenheter, informationsbehov och informationsanskaffning.
Adolescence is a turbulent time in life and gives rise to new information needs for young people. Information needs related to school subjects have been relatively well researched but few studies have focused on information needs and use related to life concerns. The purpose of this Master's thesis is to examine the information needs of a number of teenage girls in relation to their life concerns and how they meet these needs. The sample consists of twenty-one girls aged thirteen and fourteen. The research is based on literature studies and qualitative interviews combined with a questionnaire.
Arkeologisk landskapsanalys och prospektering av bebyggelselämningar och gravfält vid Alsike hage
This paper deals with archaeological prospecting for the purpose of finding a prehistoric settlement in Alsike hage, Alsike parish, Uppland. The methods being used are soil phosphate analysis, electromagnetic survey and settlement analysis. Two 20x20 meters areas have been prospected. As Alsike hage contains several late Iron Age burial fields, large splendid zones for settlement location, closeness to water as well as farmland there was a hope of locating remains of prehistoric settlement in the area. None of the prospected areas showed any distinct evidence of settlement remains.
Konsekvensanalys av dammbrott vid Tjärnviksdalen
This report consists of an anlysis of the imapct of a dam failure at Tjärnviksdalen in Ragunda, Sweden. The analysis is conducted using the EU model for environmental impact assessments, as well as a group interview. The presentation of the results in the form of a map where the water level has been raised to the level that the County Board of Jämtland considers to be possible in case of a dam failure.The result of this work is a detailed analysis of the consequenses that a dam failure would cause, the result consider everything from the direct consequences of the water column to an analysis of the chemical changes that the water would undergo.Parts of the analysis have shown that the purification centre and the old deposits will have the biggest impact on Hammarstrand. Both the purification centre and the deposits will realise chemicals to its nearest environment and because of the flooded purification centre the city will not have the ability to clean the water. .
"om du vill ha en riktig vän - köp en hund" : en granskning av Aftonbladets framställning av Jan Stenbeck före och efter hans död
In this essay I have studied Aftonbladets portrayal of the Swedish businessman Jan Stenbeck and if the reporting changes before and after his death, and if so, in which ways. With help from a qualitative syntax analysis and a content analysis I studied my material about Stenbeck during the time period 2000-09-19 to 2004-09-19. In my quantitative analysis I studied 140 articles and in my syntax analysis I studied ten articles, five before and five after Stenbecks death. The theoretical perspectives that I applied in my study is Sigurd Allerns theory about tabloid papers novelty criteria and Adam Shehatas theory about Framing. Allerns theory describes what criteria the tabloid papers have on news and Shehatas theory about framing describes the political forces behind the news who wants to set their own agenda.

Föräldraledighet som en kompetensutvecklande period i livet
The aim of the study was to examine whether parental leave can serve as capacitating period in life. More specifically our aim was to get a deeper comprehension of the abilities and competencies developed through parental leave and how these can be of use to the individual when at work. 12 semistructured interviews were conducted with employees from a large organization in the south of Sweden. The results were analyzed using a hermeneutic approach. The results of the study show that competencies and abilities such as effectiveness, organizing, multitasking, leader abilities, communication, sensitivity, limiting skills, mindfulness, acceptance, self-confidence and life balance were enhanced during parental leave.
Betydelse av laborativ matematik i dagens skola
The goal of this study is to gain knowledge and understanding of how a teacher can apply mathematics with assistance from practical mathematics. Students? point of view on mathematics within practical mathematic lessons will also be examined.
Four teachers from preschool to third grade in primary school were interviewed. 30 students from grades one to three were also surveyed. The study shows that teachers see a major benefit when practical mathematics is used in the theoretical teachings of mathematics.
Ylva Oglands socialrealism : Att göra det osynliga synligt
The purpose of this paper is to analyse how work by Swedish artist Ylva Ogland (born in 1974) function as an eye-opener for the social marginalisation of people identified with homosexuality, prostitution and drug addiction. Although highly present in reality, these phenomena were historically, and are still today, hidden from view in public discourse. I have focused on the installations Rapture and Silence and Things Seen, and the still-life painting called Xenia. I argue that these artworks carefully represent the above-mentioned marginalised groups, by way of references to comparable motives in the history of art, from neoclassicism in France, to realism and romanticism..
Illustrerade världar : -filmers bilder av ungdomars liv, i möte med ett illustrerat vuxensamhälle.
AbstractThis essay consists of an analytical study of three present-day Swedish films depiction of teenage life. From these films we like to see how youths are described, what attributes they are given, in shape of attire and different symbolic items, such as language and body expressions. The essay emphasizes which values that dominates among the illustrated teenage groups and compares it to the values and expectations that we can derive from an adult society. Here we let the school?s main determining base documents, Lpo 94 and Lpf 94, represent the dominating values of the society.Our hypothesis is that media, and also these films, creates images that affects the societies comprehension of teenagers and also how teens see themselves.
Managing Positions in a Dynamic Environment - New Technology Impact on Tactel and the Telecom Industry
The Telecom industry is facing a paradigm shift, where the industry is converging with Internet technologies and the market is becoming more sophisticated. This results in more demanding customers, and the need for offering more content and services with a focus on usability for the end-users. The operators are starting to loose both their strong position and revenue in the Telecom industry, due to new technology and the fact that other actors are starting to enter the market, offering new content and services. In the end, the operators have two choices, to become bit-pipe providers, and only focusing on network management, or keeping the control over their networks. The latter would mean that they block other actors who are taking parts of their revenue, e.g.
