Tidiga membranförändringar i hingstsperma som används för artificiell insemination :
The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.
Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala
GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.
Packning av lastbilsbyggsatser på Scania
Government regulations and customs duties restrict the import of trucks to some of the markets to which Scania tries to sell their trucks. The distribution problem due to these regulations is solved by the foreign assembly department, KD, at Scania. This means that competence is needed and costs are added not related to Scania's core operations.The aim of this master thesis has been to analyse and to evaluate alternative ways of managing the packing operations considering cost, quality and work organisation. To study and examine the work methods and operations of today and also to present methods measuring the operations effectiveness and productivity.We have used the system approach to maintain totality and to understand the component's relation to this totality. Field studies combined with studies of relevant literature and studies of other companies operations have given us the knowledge and the understanding of the packing operations needed.
Effekten av mjölkkors rang på ?antistresshormonet? oxytocin, mjölkavkastning, mjölkflöden och besökstider i mjölkningsenheten i ett automatiskt mjölkningssystem :
The study was carried out at the Kungsängen Research Centre, Department of Animal Nutrition and Management, Swedish University of Agriculture Sciences, Uppsala.
The technical development in dairy production has resulted in a housing system where feeding and milking is done automatically without human contact, a so called automatic milking system. The motives for utilising an automatic milking system, is to increase the animal welfare and to decrease the need for manual labour. However, the system does involve a change for the animals, among the effects is the deprival or the diminishment of a chance for synchronous behaviour and the animals have to agree among themselves in which order they use the feeding stations and the milking unit itself. How and if this affects the animals well-being and production is yet to be solved. A possible way to form an opinion on this, is to study the animals ranking order along with hormone profiles and production.
The purpose of this work was to study the effect of low- vs.
Dynamisk massbalansmodellering av fosfor i Östersjön
During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.
Vad påverkar en aktieanalystillförlitlighet? : En kvantitativ studie om relationen mellan tillförlitligheteni en aktieanalys och dess innehåll.
A debate in finance is whether a random investment gives the same return as carefully choose and valuing an amount of shares to invest in. Stock valuating Stock valuation is often done by fundamental valuation models, based on the company's underlying character, which tries to put a correct price on the stock. Today there are several different valuation models that can be used for this purpose. Since valuation models are only mathematical, equity research is underpinned by more subjective assessments about the company and its future.The purpose with this thesis is to describe which valuation models that are used by professional stock analysts, but also to see if the reliability on the equity research is affected by the used model to valuing the company. Furthermore, we want to see if the job that?s been done to understand the company, measured by the equity research quality, impact the reliability on the equity research.In this thesis, we have, to achieve our purpose, conducted a quantitative content analysis of 164 equity research done by professional analysts at firms listed on the Stockholm Stock Exchange. With basis in previous research, we have developed a method for determining the valuation model that is used in the equity research, the reliability on the equity research and a framework for assessing the quality of the equity research.In the theoretical framework the valuation models involved in our study are described, previous research on the reliability on the equity research and their practical use.

Aktivering av trafiksäkerhetskameror : En studie av kameraaktiveringens effekter på fordonshastigheter i Sverige
During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.
Gränsöverskridande föreställningar : En analys av dansperformance utifrån tre exempel
The essay is an effort to examine and define three examples of liminal dance performances through an aesthetic, hermeneutic and semiotic analysis. The examples are three dance or liminal performances, made by three different choreographers and performed at ?Moderna Dansteatern? and ?Dansens Hus? in Stockholm during September and October 2005. In the effort to determine the liminal and cross-over in the performances, the analysis focus on aspects such as: the character of the work, choreography, the use of scenery, stage light, requisites, conception of place and interior room, the use of costume and mask, the use of different media as text, pictures, film, and music or not using any these, and the interaction with the audience. The analysis depends on a historical background and the use of literature in the subject.
Diagnosis of Leber?s hereditary optic neuropathy (LHON) : analysis of MT-ND1, MT-ND4 and MT-ND6 in patients with LHON
Leber´s hereditary optic neuropathy (LHON), a disease affecting vision, is caused by several point mutations in mitochondrial DNA. Mutations leading to a defect NADH ubiquinone oxidoreductase protein will affect the respiratory chain and cause a disturbed ATP production. It is still unknown why this defect leads to the degeneration of retinal ganglion cells and cells in the opticus nerve as well as demyelination of axons in these areas. Analysis of mitochondrial DNA is an important tool in the diagnosis of the disease. At the present time analysis is based on cleavage by restriction enzymes, which only detects two of the most frequent mutations: m.3460G>A and m.11778G>A.
Kvinnligt och manligt i Veckorevyn : - En kritisk diskursanalys
The purpose of this paper is to explore how masculinity and femininity are constructed in the magazine Veckorevyn, through a critical discourse analysis of 18 articles from six issues in 2011. This is done by using a variety of theories and previous research results, which is gender theory, the theory of late-modern society and media theory. The analysis shows that Veckorevyn depicts virility and feminine differently. Furthermore, pointing the results from the analysis that a change of manhood and womanhood takes place in the social practice. The selection of articles from the magazine also shows that Veckorevyn seems to promote gender equality. .
Självförvållad sinnesförvirring : Konsekvenser av att fingera tillräknelighet istället för uppsåt vid gärningar som begåtts under självförvållad sinnesförvirring
This thesis, in the field of healthcare logistics, has been carried out at Hjärt- och Medicincentrum (HMC) at the University Hospital in Linköping during the fall and spring of 2012/2013. The thesis is done by two students at Linköping University at master?s level within the framework of Industrial Engineering and Management.As Sweden's county councils should not make a profit or loss, it is important that the councils are aware of how much care processes cost. Kardiologiska kliniken at HMC in Östergötland?s county council is one of the clinics that are profitable.
Bibliotek - ett ställe där man lånar böcker : En undersökning av 12-åringars syn på vad ett bibliotek är, studerat utifrån deras teckningar, uppsatser, enkätsvar och intervjusvar
This master's thesis deals with how a school class of 19 students that are 12 years old,perceive the conception of the library and its activities, and how this can be studied by usingfour different approaches: analysis of the children's drawings, analysis of the children'sessays and analysis of their answers to questions in an inquiry and in interviews. Theories ofhow children learn, develop and perceive the world are briefly presented, as we11 as theorynecessary for the analysis.The four different techniques produced in general the same result; the children displayed thesame thoughts, knowledge and values in the drawings, in the essays, in the inquiry andduring the interviews. The children participating look upon a library as mainly a building,though sometimes also a room, where there are books..
En Djupdykning i Kommunikationsstrategi : om konsten att locka folk till svenska dykvatten
Purpose/Aim: To create a communication strategy for PADI Nordic with the intention of getting Swedish divers, who have been certified abroad, to Swedish dive centers.Material/Method: The study is based on a number of personal interviews conducted with a) divers who are active in Sweden, b) divers who are not active in Sweden and c) representatives from PADI and PADI affiliated dive centers.Main results: The main reason that people who have been certified abroad do not dive in Sweden is that they regard it as being too complicated, too cold, too expensive and with nothing interesting to see. These might partly be misconceptions that can be corrected through a communication strategic effort. The best way to change this perception is by two different forms of communication. One will go from PADI Nordic straight to the divers through an email. This will have the purpose of getting their attention, making diving sound interesting and raise their awareness in preparation for the other part of the process.
Miljöcertifierade byggnader Värde för investeraren
This bachelor thesis describes why investors should invest in environmentally certified buildings instead of non certified buildings. The report provides an overview of possible factors influencing an investor in the investment process of an environmentally certified building. The report explains why building companies find incentive to build green buildings and how a cash flow method can be adapted so it can be used in the valuation process of an environmentally certified building. Environmentally certified buildings are used as a strategy to reduce emissions that threaten the environment as well as a strategy to obtain market shares for the building companies. This report focuses on the economic advantages of an environmentally certified building.The construction- and real estate industry stands for approximately 40 percent of the energy consumption in the world.
