Avelsarbete med mjölkproducerande getter ? fokus på Norge och Frankrike
The main part of the goats in the world is located in developing countries, whereas active breeding programs are mainly restricted to Northern America and Europe. Goat milk can be processed to several products and goat cheese is the main product. An organized breeding program is carried out in France and Norway but is not present in Sweden. Important selection traits for milk producing goats include milk, protein and fat yield along with protein and fat content. Functional traits have been more important the past years and they have large economic importance for the farmers.
Vad påverkar folkbibliotekens inköp av skönlitteratur för vuxna ? en jämförande studie av ett svenskt folkbibliotek och dess engelska motsvarighet
The purpose of this bachelor thesis is to do a comparativecase study between a public library in Sweden and one in England. Our aim is to examine what factors affect alibrarian in charge of purchasing fiction for adults and to what degree. We have used two methods of study, specifically semi-constructed interviews with two librarians and text analysis of policies in place at each library respectively. Our research questions share the above mentioned context and should therefore be read with that backdrop:-How is selection and purchase covered in the policies?-What selection criteria are used by the respondents?-What differences are there regarding the decision making? -How can the viewpoints be explained?Our analytical framework was based on three arguments namely market demand, quality and social inclusion when examining our material.
Spawning site selection of brown trout in habitat restored streams
During the timber floating era, most of Sweden?s watercourses were altered. This decreased the amount of available spawning habitats for salmonids, and hence had a negative effect on the riverine brown trout (Salmo trutta) populations. Reconstruction of spawning grounds is today a common measure in restoration of altered streams in Sweden. However, very little evaluation of the effectiveness of these reconstructed spawning grounds exists.
Omvandling av granskog till ädellöv i södra Sverige ? fallstudier från Söderåsens nationalpark och Raslångens ekopark
I Sverige och stora delar av Europa har det planterats gran, Picea abies, på marker som tidigare varit lövdominerade. Idag restaureras ädellövskog på dessa marker i ökad omfattning, bland annat för att gynna skogens biologiska mångfald och rekreationsvärden. Syftet med detta arbete var att undersöka överlevnad och tillväxt av ek, Quercus robur, och bok, Fagus sylvatica, som planterats efter gran i Söderåsens nationalpark och i Raslångens ekopark i södra Sverige. I Söderåsens nationalpark undersöktes plantutvecklingen tio år efter plantering på öppna hyggen (ek och bok) eller under björkskärm (bok). För Raslångens ekopark var syftet att undersöka om inversmarkberedning och hägn påverkar initial etablering och överlevnad hos bokplantor på öppna hyggen.
Resultaten från Söderåsen visar att ek och bok tio år efter plantering kan nå en hög överlevnad och god tillväxt med hjälp av fungerande hägn och regelbundna röjningar.
Development of a real-time RT-PCR for quantification of bovine TLR4 mRNA and evaluation of its use during a BRSV vaccine challenge
The Bovine respiratory syncytial virus (BRSV) causes bronchiolitis and interstitial pneumonia, predominantly in calves, and is a major cause of bovine respiratory disease worldwide. In humans, BRSV is paralleled by the closely related Human respiratory syncytial virus (HRSV), an important cause of respiratory disease, most severe in infants.The clinical signs and pathology during RSV infection is caused, not only by the direct effects of viral replication, but also by the response of the host immune system. The immunopathology of RSV has long obfuscated our understanding of the disease, and development of effective treatment and vaccines will be very difficult until greater knowledge is gained.One of the components of the immune system that has come into focus in RSV research the last few years, is the Toll-like receptor 4 (TLR4). The TLR4 receptor is well known as the receptor that binds lipopolysaccaride (LPS), and initiates the host response to bacterial infection. Recently, it has been shown that the fusion protein of RSV also interacts with, and up-regulates the expression of, the TLR4 receptor.
Val av källor : En studie av de anställdas informationssökning inom företaget Viking Line
Nine out of ten larger companies have an intranet today which is supposed to improve the communication withinthe company and save money. A great part of these intranets were established in the beginning of the 1990?swithout giving any thought to the users and their needs. How does the communication inside the corporationslook like when the intranets that are supposed to be the source for every information request, aren?t usable? Whatother sources do the users use and how much?The aim of this master thesis is to examine information source selection at a specific company.
Lärares uppfattning omutomhuspedagogikens påverkan på barn med koncentrationssvårigheter : ? i den traditionella undervisningen
The objective for this study was to acquire a greater insight if children with concentration difficulties are assisted by outdoor education in the traditional teaching. With the use of a qualitative methodology four teachers were interviewed. The outcome gave evidence for that the teachers thought that outdoor education has a positive outcome for children with concentrations difficulties. The findings were divided into three key categories: the teacher?s reflections about outdoor education, outdoor education for children with difficulties in concentration and if there was any difference in how the children behaved indoors after having educations outdoors..
Stopover duration and field site selection by whooper swan (Cygnus cygnus) at Lake Tysslingen, Sweden
The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.
Evaluation of preanalytic methods in order to shorten the processing time before identification of fungal microorganisms by the MALDI-TOF MS
Identification of fungi is based on macroscopic observations of morphology and microscopic characteristics. These conventional methods are time-consuming and requires expert knowledge. For the past years Matrix-assisted laser desorption ionization-time of flight mass spectrometry has been used for routine bacterial identification in clinical laboratories but not yet in the same extension for fungi. In this study three preanalytic preparation methods for fungi were evaluated in order to shorten the processing time in routine laboratory performance.Clinically relevant strains (n=18) of molds and dermatophytes were cultivated on agar plates and prepared according to the different preparation methods for protein extraction. Each strain was analyzed in quadruplicate by the MALDI Biotyper and the database Filamentous Fungi Library 1.0.The results showed that the genus and species identification rates of the least time-consuming direct extraction method were 33% and 11% respectively.
KYRKLIGT KULTURARV I BEREDSKAPSPLANERING Logistik, roller och urval
With the political situation that prevails in the world, the need for contingency planning for the ecclesiastical heritage has become actualized with the aim of protecting the churches and their assets in war and armed conflicts. In accordance with Kulturmilj?lagen (SFS 1988:950) chapter 4 ? 15a, the Church of Sweden and its organizational parts are responsible for ensuring that contingency plans for the ecclesiastical heritage are established. In the legal statutes, it is not clear how this is to be carried out, who is responsible for all practical aspects or what is to be protected, something that creates gaps of knowledge regarding logistics, roles and selection. This means that there is currently a lack of principles and practice around the protection of the ecclesiastical cultural heritage, as contingency planning for cultural heritage is a fairly new phenomenon that has not been practiced in times of peace.
Use of feline TK1 as a biomarker in disease monitoring
Serum thymidine kinase 1 (TK1) activity is used as a tumor marker in disease monitoring in veterinary and human medicine. TK1, an intracellular enzyme, is involved in a salvage pathway of DNA precursor synthesis.
TK1 is used in DNA precursor production by catalyzing the transfer of the gamma-phosphate-group from a phosphate-donor to the 5?- hydroxyl-group of thymidine forming thymidine-monophosphate. Nucleoside monophosphosphates are finally converted into thymidine-triphosphates. TK1 activity significantly rises in the G1 and the S phase of the cell cycle.
Evidensbaserad praktik och underhållsbehandling - begränsningar och möjligheter
It appears from today's debate about the quality of social work and addiction treatment that largely focuses on the impact of recent various interventions in the hope of being able to alter social work's role in society and also the organizational structure. The debate points to a part of the 1970s social welfare debate. Today's aspirations to establish an evidence-based practice can hardly be expected to solve the social services basic dilemmas is that it always have to do something, despite the many times you cannot get clear instructions on which funds should be used by law or science. Even if you follow the rules and practices based on scientific studies should the importance of various key initiatives to remedy deficiencies in social service work with addicts in large part depend on how, in these initiatives define the term "evidence-based practice" and what steps will be indicated for to develop practice.
My starting point was to explore how evidence-based social work in connection with medication-assisted treatment for opiate addiction look, which evidence-based interventions Social Services currently uses in connection with medication-assisted treatment for opiate addiction, as well as how to work with it in the ordinary course of business. The study showed that social services have become better at using these methods in recent years and that today there are more tools available than before.
Effekten av neutrala påståenden på social önskvärdhet i självskattningsformulär
This study investigated the effect different contexts have on personality items when they are framed more neutrally. The study was based on a five-factor personality inventory originating from International Personality Item Pool. The inventory consisted of 50 original and 50 neutral personality items and in addition 28 items measuring social desirability. The sample consisted of 150 students from the Department of Psychology, Lund. The students were divided into three instruction groups differing in context.
Val av område och områdesskydd för Natura 2000 med skogshabitat : En jämförande studie av fyra län i Sverige
The Natura 2000 Network is one of the European Unions many tools concerning nature conservation, and is without comparison the premier contribution when it comes to halting the loss of biodiversity. This essay is a case study on how the regional work with the Natura 2000-network has been carried out in four different counties. These counties are Södermanland, Västernorrland, Jämtland and Örebro. They have been compared based on the theoretical concept of sustainable development. This essay describes how the officials in the County Administrations view the regional implementation of Natura 2000 when it comes to the selection of Natura 2000-sites with forest habitats and the creation of an additional protective measure.
