Bedömning av spermiemotilitet i färsk, kyld samt selekterad hingstsperma med Qualisperm :
This EEF-project is a part of a larger project at SLU, Division of Reproduction,
Dept of Clinical Science, with the intention of developing and evaluating new
methods for the assessment of stallion semen quality. Over the last 10 years there
has been an increase in the use of artificial insemination with cooled semen in
Swedish horse breeding. At the same time, foaling rates have decreased. This has
lead to a need for new and better methods of assessing the quality of stallion
semen. This EEF-project was based on an objective method to calculate motility,
with QualispermTM, in fresh and cooled stallion semen, and after selection.
Today sperm motility evaluation is mainly done subjectively by visual assessment
with a light microscope, and the correlation between these motility results and
fertility have varied.
Trädens betydelse för gatan :
?The trees importance to the street? discusses just that, the trees importance to the street. The purpose of this paper has been to examine what influence the trees have on streets. By writing about good examples of how trees can add good qualities to a street I wish to inspire to more use of trees in future city-planning.
I have examined three streets in Malmö and three streets in Berlin and analyzed the trees influences there through the help of literature by three authors: Great Streets (1993) and The Boulevard Book (2002) by Allan B. Jacobs, Trees in Urban Design (1993) by Henry F.
Förluster av nedströmsvandrande fisk vid turbinpassage : En fallstudie för att främja den småskaliga, såsom storskaliga vattenkraften
The expansion of the Swedish hydro power has contributed positively to the reduction of the environmental impacts from the fossil fueled power production. In the same time the extensive expansion has been proved to cause negative ecological and local environment impacts of a stream. This, in turn, has been affecting the biodiversity and fish stock negatively, which has been reduced. One of the underlying problems is the lack of possibility for the fish to pass the plants, but it is also directly correlated to the mortality rate of the fish passing through the turbine, which this study is investigating.The mortality rate has been computed for three different locations in Sweden, Untra, Tännfallet and a third one whose location is confidential, and is denoted as Case 1, 2 and 3. The model used to calculate the mortality rate in this investigation is based by existing blade strike models and knowledge and are investigating the death due to mechanical injuries from collision with a runner blade in the turbine.
Nyckelbiotoper - urskogsrester eller kulturprodukter? : beståndshistorik i tolv nyckelbiotoper i Lycksele kommun
Since 1993 the Swedish Forestry Administration conducts a nation-wide inventory of wood-land key habitats covering all forest land in Sweden. The inventory aims at mapping and describing habitats where redlisted species occur or can be expected to occur. According to the inventory stand history is crucial to the presence of red-listed species. However, the current knowledge of stand history in woodland key habitats is very limited.
The purpose of this work is to describe stand history in woodland key habitats, i.e. fire history, human activities - mainly cuttings - and structural changes.
Hur kan eleverna nå målen i svenska för skolår 5? : en studie utifrån ett lärarperspektiv
Statistik från Skolverket (2006) visar att ungefär var femte elev i Upplands-Bro Kommun inte klarar det nationella ämnesprovet i svenska för skolår 5. Då vi har vår verksamhetsförlagda utbildning i denna kommun blev vi nyfikna på att undersöka detta närmare. Vi valde att utgå från ett lärarperspektiv och en lokal bild av lärarnas uppfattningar av det nationella ämnesprovet i svenska och hur de arbetar för att komma åt problemet. För att ta reda på det använde vi oss av intervjuer med åtta behöriga lärare. Vår studie utgår från två frågeställningar: Vilka faktorer kan enligt lärarna i Upplands-Bro Kommun påverka att en elev inte når de nationella målen i svenska? Vilka målstrategier har lärarna i Upplands-Bro Kommun för att eleverna ska uppnå de nationella målen? Med hjälp av teoretisk litteratur formas vår bakgrundsdel, med utgångspunkt från Skolverkets rapport (2001), ?Utan fullständiga betyg?, Bronfenbrenners utvecklingsekologiska teori, målen i svenska, det nationella ämnesprovens bakgrund och syfte, skolans ansvar och styrdokument och delar ur dagens skoldebatt.
Integration mellan informationssystemen & mobila tjänster - Design, utveckling & utvärdering av en prototyp
The company Pilotfish has developed the system MIVEO which is used by car-sharing to wirelessly monitor, book or otherwise manage a fleet of cars. In a car pool the system has three different types of users with varying degrees of eligibility. These are end users, administrative and service personnel. We have chosen to focus on opportunities to streamline the administrator and service personnel work with a mobile service, as these users of MIVEO often are movable and mobile. From this position we have in the study attempted to answer the following question: How can mobile services used to streamline administrative tasks? This study is about developing a mobile application that will contain the same features as the existing system, but must be mobile suit.
Samverkansplanering : en jämförande studie mellan praktik och teori
Collaborative planning
? a comparative study of theory and practice
Why
There is today, according to my experience, a growing interest and
demand for a more inclusive and transparent planning process. Also,
if we are going to be able to reach a truly sustainable society it is my
belief that there is a need for a more integrated collaboration between
different actors. Where the social, economic and ecological values can
influence and benefit from each other. The question then is, how can
the planning system accommodate that kind of collaboration?
Purpose
My aim for this thesis has been to study a selection of the theoretical
work that exist about collaborative planning.
Kommission och andra uppdragsformer - en obligationsrättslig analys och jämförelse av gällande rätt
Den 1 oktober 2009 trädde en ny kommissionslag (KommL) i kraft. Syftet vara att skapa tidsenliga regler och ett mer jämbördigt avtalsförhållande. För att uppnå detta syfte fick lag om handelsagentur (HagL) stå modell vid utformningen av KommL:s nya bestämmelser och lagarna är nu därför i stort överensstämmande. Det finns dock fortfarande skillnader mellan lagarna som är viktiga att uppmärksamma då det på flertalet områden är oklart vad som gäller vid tillämpningen och olikheterna i vissa fall kan medföra stora konsekvenser för parterna. I denna uppsats behandlas regleringen i den nya kommissionslagen och vilka skillnader som finns i förhållande till HagL samt effekterna av dessa skillnader.
Going concern utlåtande i revisionsberättelsen : En studie om svenska konkursdrabbade aktiebolag
In the beginning of the 21th century several successful companies filed for bankruptcy. These bankruptcies have been known as large accounting scandals and the largest scandals did Enron and Worldcom stand for. These bankruptcies arose without any warning signal from the auditors about the companies? financial problems and their inability to continue as a going concern. The bankruptcies damaged the reputation of auditors and broad criticism has developed at the auditors? inability to discover companies? financial problems and their unwillingness to reveal a going concern opinion in the audit report.
Zoonotic Pathogens at the Interface between Humans and Animals in Cambodia, a Rural Approach
A zoonosis is a disease or infection that is naturally transmitted between vertebrate animals and humans. The majority of infectious diseases that affect humans are zoonoses. Environments where wild animals, domestic animals and humans live in close proximity with no or small boundaries in the ecological system favor the transmission of diseases between animals and humans. The above described situation is more common in low income countries, where humans and animals live in high density and zoonoses are generally more common. The study was conducted in Cambodia.
GMO Food Products - The issue of marketing and selling them in Europe.
Title: GMO Food ProductsThe issue of marketing and selling them in Europe - A Business and Legal Perspective.Author: Shane KingSupervisors: Anneli Carlsson and Ewa RabinowiczProblemThe European Unions regulations in regard to GMO?s and the approval process for both release into the environment, and onto the market, has been under fire by the USA along with Canada and Argentina. The WTO has ruled on this issue in favour of USA et al.The problem that was identified was in regard to consumer opinion in the EU. How could the EU meet its numerous international trade obligations while at the same time meetingthe needs of the citizens of the Union? Added to that was the issue of whether or not the?EU? perspective was indeed an EU perspective or rather the perspective of a fewMember States.
Effekt av ras och säsong på nötkreaturs avbetningsgrad av konkurrenskraftiga betesmarksväxter :
Grasslands which have been actively managed for a long time and which in modern times have not been subject to cultivation such as fertilization are called semi-natural grasslands. These rare and species-rich areas hold an ecological, biological and historical value and if the management stops these areas will likely diminish. More effective agricultural systems and a declining number of grazing animals have in Sweden, among other countries, made semi-natural grasslands less valuable as foraging areas. Shrubs and fast growing plants rapidly colonize abandoned semi-natural grasslands, threatening biodiversity.
The objective of this experiment was to determine the effects of breed and season on diet composition, with special reference to four competitive species found in wet areas ? in cattle grazing heterogeneous semi-natural grasslands ? and thereby contribute to improved management of these areas.
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.
The physical environment is also a part of the total interpretation of a town.
Vad styr kunden till köp inom elektronikbranschen? : En studie av tre ONOFF-butiker
En färsk undersökning visar att en av tre köper ny mobil vartannat år, var femte har tre tv-apparater och fler än var fjärde svensk äger en spelkonsol. Konkurrensen i hemelektronikbranschen hårdnar med den tyska kedjan Media Markts intåg i Sverige. De etablerade kedjorna får det allt tuffare och risken för utslagning ökar. Konsumenterna blir vinnarna som gagnas av lägre priser och ett större utbud. Många företag går i den fälla som innebär att de konkurrerar med låga priser, vilket ibland kan vara effektivt, men som många gånger bara betyder att man ger bort de vinster som krävs för att skapa och upprätthålla bestående fördelar gentemot konkurrenterna.
Konsten att lyckas med förankring
The purpose of this thesis work is to formulate a model with methods that describe key success factors to get understanding and awareness in organizational change projects. We have used a project within the township of Gothenburg as a case and connected to this single project the purpose is to identify key success factors to get understanding and awareness among employees within the township of Gothenburg. We hope that our result will be useful in other large organizational change projects. Theoretic basis for our study have been models and methods, while our purpose have been to construct a model with suitable methods for anchoring. Theories about coaching and process management are examples of methods to get understanding and awareness among employees in change projects.
