Inverkan av utfodringsnivå och miljö på reproduktion och hållbarhet hos rekryteringskvigor :

This study is based on an earlier interdisciplinary study made by Redbo et al., (2000), Extensive cattle production systems ? out wintering, which lasted over two winters, 97/98 and 98/99, with two groups of heifers indoors and two groups of heifers outdoors raised in different environments, indoors or outdoors during their second winter. Both indoor and outdoor heifer groups were fed grass silage ad libitum throughout the experimental period that lasted from October until May. The objective of this study was to evaluate the long term effects of being raised in these two environments. This study includes data collected during the period lasting from the start of the experiment of Redbo et al., (2000) until the heifers had calved a second time and the results mainly deal with the performance of the animals after the experiment during their first two calvings and their first lactation.

Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Barn och sorg

The purpose of this study is to highlight some aspects of the increased usage of tablets in preschool environments by answering the questions: what does the tablet become in the preschool environment, how much freedom does the children have over its usage.To answer these questions a series of observations were made at two different preschools. The observations were then complemented by interviews with teachers at the same preschools.This qualitative study focuses on some of the didactic questions regarding the tablets, based on a theoretical framework that is within the design-oriented perspective; which addresses the children's? autonomy, the institutional framework and affordance.Our conclusion is that the tablet?s introduction in the preschool has helped the teachers in numerous parts of their documentation, but we can also see that the children's opportunities to make choices regarding the tablet are more limited than with any other resource on the preschool. In our results we also see that when the children get access to the tablet they receive a learning experience, which among other things, strengthens their language skills and their social interaction with each other..

Arbetsprestation, samarbete och sammanhållning i påfrestande arbetsmiljöer: en fallstudie inom beroendevård

Stress is commonly found in society today. This paper aims to examine how work performance, cooperation and team spirit are maintained in demanding work environments. By studying two departments in a public hospital that practises addiction care, our findings suggest the following: If the experienced stress is mainly connected to challenge stressors, it has a positive effect on work performance. By organising work through mechanistic and organic structure, the handling of qualitative and quantitative stress is facilitated. As a consequence, first and foremost cooperation can be maintained, but also work performance and team spirit.

Gestaltning av en takträdgård

Gastric ulcer is a common disease among pigs in the whole world where an intensiveproduction occurs. It is mainly the upper region, the nonglandular region of the stomach thatis affected. Gastric ulceration is a disease with several risk factors. The factor that seems tohave the largest impact on the development of gastric ulceration is a small particle size of thefeed. The reported prevalence of gastric ulceration differs from 5 to 100 % and it is a largeherd-to-herd variation.

Passive acoustic diver detection

This report discusses a method to detect divers in harbour environments usingpassive acoustic detection. The goal was to achieve as high detection as possiblewithout having too high false alarm rate. A short execution time was also desirable.By using the characteristic of an inhalation a band-pass filter was applied to the signalto improve the signal to noise ratio. After the filtering an energy estimation of thesignal was made. This energy estimation was later used in a frequency analysis, whichcould tell us if there were enough energy in the frequencies that correspond to adivers breathing frequency.

Miljöarbete inom transportsektorn En fallstudie av hur miljömål kommuniceras inom åkeriverksamheten i Green Cargo

Problembakgrund: Transportsektorn och framförallt vägtransporter är den enskilt störstaproblemområdet med avseende på kolidioxidutsläpp i världen. Förändringsåtgärderna somhittills har gjorts inom sektorn är otillräckliga, främst eftersom det totala antalet transporterfortfarande ökar. Företag, främst industriländerna, har under de senaste decennierna börjatintegrera miljömål i sina företagsstrategier. Det statliga transport- och logistikföretaget GreenCargo bildades år 2001 och samma år införde företaget ett balanserat styrkort med integrerademiljömål. Meningen var att arbetarna skulle känna sig mer delaktiga och se att det går attpåverka utfallen.

Stereotypa förklädnader? : En tematisk läsning av John Greens The Fault in Our Stars

Syftet med min kandidatuppsats är att undersöka hur föreställningar om kön kommer till uttryck i barnlitteratur och på vilka sätt barnböckerna förhåller sig till traditionella normer och värderingar gällande kön och könsroller.Med utgångspunkt i fem populära barnböcker undersöks följande frågeställningar:Vilka roller tar personerna i boken och hur förhåller sig dessa roller till traditionella föreställningar om vad som är kvinnligt respektive manligt?Vad gör personerna i boken som kan tolkas som stereotypt respektive normbrytande?Vilka identiteter har personerna i boken, hur ser de ut, vad har de för kläder, leksaker och färger runt sig?Avslutningsvis kommer jag också att jämföra barnböckerna och diskutera likheter, skillnader, övergripande mönster, samt diskutera möjliga förklaringar till varför det ser ut som det gör..

AUSTERS 1:61 - ett fritidshus på Gotland

A few hundred metres from the beach on Fårö, Gotland, is a small lot with pine trees, green moss and wild fl owers situated, owned by my brother and sister. Eventually they would like tobuild a summerhouse here, in close proximity to their relatives. My project is a proposal for the summerhouse at the site, within the restrictions of 61 m² building area, with focus on interior,exterior and the environment.My proposal is a house close to the surrounding nature, with reference to the the building tratition on the island and with local materials. Orientation to the sun, road and neighbours hasall infl uenced my ideas of this house and the relation between inside and outdoor living, were important in my creative work. The aim was to create a house made for the family and theirholiday lifestyle and allowed consideration for the possibility of a growing family with more children.

GRAFISK PROFIL TILL EN BLOMSTERHANDEL - corporate identity for a flower shop

This project aims to explore how to create a working concept-based flower shop visual identity, with focus on brandig, eco-branding and visual communication. My main question is: How do I create effective visual communication for an ecological flower shop? The results of this thesis are that there are things to consider when creating a visual identity with an ecological concept. The most important question is if there is any benefit for your company to go green, otherwise positioning of your company will be hard. What I realized during the design part of my project was that if I use the methods described in this thesis and consequently applying my choices after the flower shops identifying words, a working concept-based visual identity will be possible to create..

Det politiska i författningspolitiken - en idéanalys av riksdagsdebatten i anknytning till Grundlagsutredningen

This essay revolves around two questions: what is the nature of politics, and what kind of political order ensures a high rate of citizen participation? By using Cantal Mouffes theory on the political this essay shows how different understandings of the nature of politics can lead to diverging views on what forms democracy should take. Two such understandings are identified; one that sees the nature of politics as characterized by conflict and power, one that sees it as a space for cooperation in search for the common good. I trace these different ideas about the political in the parliamentary debate concerning Swedish constitutional reform. I conclude that the left-of-centre parties hold a view of the political closer to the conflict-perspective, while the green party together with the liberals/conservatives lean closer to the opposite view..

IKT som verktyg för lärande i historia : en studie av gymnasielärares syn på IKT i historieundervisningen

This essay examines the possibilities for the use of ICT for learning in the subject of history. By interviewing history teachers in upper secondary school about their experiences and thoughts regarding the subjects of learning, history and ICT, as well as the relations there between, based on Mishra and Koehlers TPACK model, I come to the conclusion that ICT may enhance learning in history. I also conclude that ICT may create new learning environments in history, where knowledge may or may not grow.The more unique ways of using ICT in history, compared to other school subjects, appears to be the possibility of using a variety of new sources, for example digitized primary sources from archives, that perhaps will motivate students, and make it possible to work from a con- structivistic point of view in history.Other unique possibilities are to satisfy the need of concretizing and visualizing the history being taught, by using a broad range of different media when presenting it. .

Utvecklingspotential till en mer attraktiv bostadsmarknad : En teoretisk värderingsanalys av stadskvaliteter och dess relevans för bostadsbyggandet

Stockholm has in recent years experienced a strong population increase but despite that fact, the demand for housing has not been followed by enough housing contracts. According to forecasts, growth in population will further be continued upward. With more condominiums than rental units on the market, new apartments are too expensive to live in. This creates unsustainable problems for those in lower classes of society. Creating a housing market in the periphery of Stockholm is not sustainable from a social perspective.

Moral över lag : beslutsfattande dilemman

The purpose of this paper has been to reach a greater understanding in how moral inflicts social workers way of handling everyday situations. In what way, if in any way, moral comes to play a part in the making of decisions. In order to reach this understanding we have interviewed two different groups of social workers which we also later on came to compare . One of the groups contained six interviewees and the other group contained five interviewees. Both of these groups were in the ages between 27 ? 52.To shed some light over this phenomenon did we use two theoretical perspectives, first Kant?s morale theory and second, consequentialistic utilitarism theory.As a result from the interviews we?ve made, we came to an understanding that the meaning of morale and in what way it can be applied in the everyday work differs between these two professional groups.

Kontinuerlig temperaturmätning i bädden på gratevagnar

Luossavaara-Kiirunavaara Aktiebolag (LKAB) är en gruvdriftskoncern med järnmalmsbrytning som huvudsaklig verksamhet. En av produkterna tas fram genom att raffinera järnmalm till pellets vilket är en efterfrågad produkt vid ståltillverkning. Vid sintring av råkulor till pellets är temperaturen väsentlig för att få så hög oxidation som möjligt av magnetit till hematit och för att få rätt fasthet. För att reglera värmen bör temperaturen mätas bland råkulorna eftersom det är kulornas temperatur som är det viktiga.                                 Projektet går ut på att undersöka möjligheterna att mäta temperatur bland råkulor på gratevagnar som åker genom en pelletsugn med ett permanent mätsystem. Här ställs höga krav på mätsystemet på grund av miljö, portabilitet och drifttid.Miljöanalyser gjordes för att ta reda på vilken påfrestning ett mätsystem bör klara av. Förslag om placering av mätutrustning framtogs genom kartläggning av miljön.
