Estimation of heterosis and performance of crossbred Swedish dairy cows
The heterosis effect and breed group effect of crossbreds between Swedish Holstein (SH) and Swedish Red (SRB) was estimated in this study. Observations on cows born between 1990 and 2012 were used to estimate the heterosis effect and breed group effect for several traits included in the Nordic breeding goals: production, fertility, udder health, calving performance, survival and other diseases.
Breeding within the Holstein dairy breed has earlier been focused on increased milk production and conformation. This, combined with an intensive use of individual animals, has resulted in a radical increase of milk yield in the Holstein dairy cow population all over the world. However, this breeding strategy has resulted in increased inbreeding and several functional traits have impaired.
EN KONSTRUERAD SITUATION ? I EN FORTSATT TANKEPROCESS KRING KÖN OCH SEXUALITET
ABSTRACTThe purpose of this essay is to investigate possible questions generated by theperformance/installation Har hon inget vettigare att göra? Du då. Har du inget annat att hitta på än att ståoch glo på henne? by the artist Elin Wikström. The Constructed Situation invites the spectator to be apart of a continuing process of thought.The subjective feeling makes an important insight to the work through methods of the aestheticsand the performative., mainly from Margaretha Rossholm Lagerlöf.
Organisationsstrukturen & styrsystemets användbarhet - En fallstudie av Perstorp Performance Chemicals
Syfte:Syftet är att analysera och beskriva styrsystemets användbarhet utifrån vald organisationsstruktur i ett decentraliserat företag. Problem:Eftersom strategin utgör en grundtanke som ska förena och skapa en gemensam riktning för individer eller organisationer är det en central del av en chefs roll att sträva mot att skapa framgångsrika strategier och att implementera dessa. Enligt forskning kommer företagens diversifieringsstrategier leda till att de decentraliseras och organiserar sig efter divisioner. En decentraliserad, divisionaliserad organisationsstruktur har fördelar men också nackdelar. Eftersom organisationsstrukturen och styrsystemet ska samverka ställer strukturen krav på styrsystemet.
3D-skrivarens intåg i immaterialrätten : - Om 3D-bilder, 49 § URL och vikten av lämpliga avtalslicenser
The current study aimed to test the public self-consciousness impact on creative performance. An experimental design was used in which 40 participants were randomly assigned to two groups, one of which was the experimental group and the other was the control group. A mirror was used in the experimental group to induce public self-consciousness among the participants while they performed creativity tests. A consequence test was used where the participant had to give suggestions for the given scenario "What would happen if everyone became blind?" which was then measured in the number of proposals (fluency).
Tubular polyethylene biogas digesters : development and testing of a biogas technology in Malawi to reduce deforestation and support climate change mitigation and adaptation
The aim of the study was to install a biogas system consisting of three tubular polyethylene biogas
digesters at a rural household in Malawi and to evaluate the constructed biogas system with regards
to relevant system parameters. The purpose was to evaluate if the technology is a possible solution
to reduce deforestation and support Malawi in climate change mitigation and adaptation.
The study was carried out in the southern part of Malawi in cooperation with the University of Malawi. Locally available materials were used to construct and install the system. Three different feed materials, cow, goat and a mix of cow and goat manure, were used in order to determine
which one was best suited to utilise as a digester substrate. After the installation, measurements of
temperature, pH, biogas production, biogas composition and system functionality were made.
The results of the study show that a biogas system with tubular polyethylene biogas digesters can be successfully installed at a rural household and that the most suitable feed material is a mix of cow and goat manure.
Varför ska vi välja just dig? : En studie om trenden performance urval och dess inriktningar.
I dagens arbetsliv används olika urvalsprocesser för att finna lämpliga kandidater till lediga tjänster. Inom en traditionell urvalsprocess selekteras kandidater utifrån en skriftlig ansökningshandling där kandidatens formella kompetens i form av tidigare meriter och erfarenheter lyfts fram. Den traditionella urvalsprocessen har nu utvecklats och delvis ersatts av nya metoder för att finna lämpliga kandidater. Utvecklingen mot nya urvalsmetoder ser vi som en trend i arbetslivet. Trenden har uppstått då en rad inriktningar har uppkommit som ett komplement till den skriftliga ansökningshandlingen.

Utveckling av dynamiska farthinder
The aim of this Master of Science Thesis is to develop guidelines and improvementsuggestions of RiNOVA Traffic AB?s dynamic speed bump. The project started with athorough pre study of the design and its function to find out how passing vehiclesaffects the dynamic speed bump. The majority part of the pre study was to createnecessary mathematical models to explain the arisen forces and strains.The results of the mathematical models gave necessary information about the designregarding weaknesses and flaws. The most critical ones where those which interferedwith the design?s performance and reliability, and therefore needed to be corrected.These problems where more thorough analysed and discussed with experts before thefinal guidelines and improvement suggestions where developed.The parts of the design that had to be redesigned were the extension springs and thebearing that enables the dynamic properties.
Dragshow på de sju haven : ? en analys av Elizabeth Swanns karaktär i Pirates of the Caribbean
AbstractTitle: Dragshow on the seven seasNumber of pages: 51 (56 including enclosures)Author: Therése PlastrougiTutor: Ylva EkströmCourse: Media and Communication Studies CPeriod: Fall 2007University: Division of Media and Communication, Department of Information Science, Uppsala UniversityPurpose/Aim: My main purpose with this paper is 1) to study how film as a media can subvert traditional gender constructions and 2) study the character of Elizabeth Swann in the trilogy Pirates of the Caribbean through four dimensions; Gender performance, Class, Desire and Power.Material/Method: My main material is the trilogy Pirates of the Caribbean. I have studied Elizabeth?s character based on semiotic and narratological methods.Main results: Film as a media possesses the full potential to change traditional gender roles, but the full subversion is denied due to the heterosexual matrix. Elizabeth?s character almost completes her subversive journey throughout the trilogy, but since she too is a victim of the heterosexual matrix, a full subversion is not possible.Key words: gender performance, class, desire, power, sex/gender, subversion, narratologic, semiotic, queer, feminism, pirates of the caribbean, intersectionality, parody.
Framtagning av nyckeltal som indikerar kvalitetsbristkostnader : Development of key performance indicators revealing the cost of poor quality
Since the 1980s, companies have taken a larger interest in quality and it´s economic impact within the company. Having the knowledge that it´s not quality that costs money, but it´s rather the lack of quality. The work immerses itself in the field of cost of poor quality and the development of key performance indicators.The thesis is performed at Bufab Holding in Värnamo. Bufab Holding is a trading company which mainly buys and sells C-parts. C-parts include fasteners, other small metal-, rubber- or plastic parts such as wires, springs and electronic fasteners.The aim of this thesis was to make a survey of the cost of poor quality and to find key performance indicators (KPI) for cost of poor quality that can be continuously monitored.
Performance of laying hens in a cognitive bias task : effect of time since change of environment
In the debate on laying hen welfare, and specifically housing conditions, the main focushas been on physiological and behavioural measures. What is lacking is knowledge of howthe hen experiences the situation ? her state of mind.This study is an attempt to gain insight into the private mental states of former batteryhens. It uses a cognitive bias method based on spatial judgement, i.e. judgement of aambiguous stimulus placed spatially in between a reinforced and an unreinforced stimulus.This method has previously shown differences in judgement by animals in enriched versuspoor housing.

Several benefits areforeseen, reduced lead-time, less costs, shorter Time To Market and better quality.Development and verifying will be carried out on block level. Today the separators arebeing tested as a complete unit. A number of factors affect the test results and problemsthat are encountered can be hard to identify.
Development of Liquid Cooling for PCs
In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

Frånluftsvärmepumpens möjligheter i flerbostadshus
If a building is heated by a heat pump, it is of high importance that the heat pump has a high coefficient of performance. An exhaust air heat pump extracts heat from the building?s exhaust air. The air has a relatively high and constant temperature all year around, leading to a high seasonal coefficient of performance. This thesis examines whether it is profitable to complement an exhaust ventilation system with an exhaust air heat pump in an apartment block that already has geothermal heat pump, district heating, oil- or biofuel heated system.
