The use of artificial insemination in dairy farms in urban/peri-urban Kampala, Uganda : a study of knowledge, attitude and practices
Uganda is one country with fastest growing Populations in the world and with more than 25% of the population living in poverty. There is a rapid rural urban migration with increasing demands for food for low income earners especially in these areas. One way to mitigate food insecurity is to increase milk and meat production efficiency, and thus reproductive performance of cows is crucial for good production. A well-documented strategy for improving dairy cow productivity through faster genetic improvement is to breed dairy cows using proven semen via artificial insemination (AI). AI has been used in Uganda for over 60 years but only less than 10 %, a small population of the country?s herd has been bred that way.
The aims were to study knowledge, attitude and practices factors influencing cow fertility results on dairy farms around Kampala using AI and to propose ways of promoting increased use of AI in Uganda.
Hur hanteras vildsvinets (Sus scrofa) populationstillväxt i Sverige idag?
The wild boar was reintroduced to Sweden in the 1970´s from enclosures that they had escaped from and by a government decision in 1988 they were considered a part of the natural fauna again. The purpose with this report is to examine the effects of the wild boars? reintroduction both on their welfare and on other aspects, such as how their population growth affects Sweden. This was done by gathering information from scientific literature and by performing three interviews. Another purpose is to briefly overlook live trapping and other common regulation methods.
Minskad utbredning av apollofjäril, Parnassius apollo, i södra Stockholms län : En studie av möjliga faktorer utifrån artens habitatkrav
The Apollo butterfly, Parnassius apollo, is categorized as Near Threatened (NT) in IUCN Red List. Today in Sweden it is found only in strongly fragmentized Populations. In the county of Stockholm, P. apollo exists exclusively in some islands of the archipelago and with one mainland population in Stora Vika. This study has the purpose of expanding the knowledge of the local conditions for the butterfly in the south parts of the county of Stockholm and thereby contributes to a sustainable land management that can preserve the Apollo butterfly.A comparative study was done between areas where the butterfly today have: a stable population (Stora Vika, Utö and Ålö), has disappeared (Muskö and Yxlö) or is strongly declining (north part of Ornö).
Kulturskolan i integrationens kraftfält
Title: Access to cultural education in a multi-ethnical context.The right to dance and play an instrument, to paint and work with film is taken for granted by many children in Malmoe today. The agenda explicitely phrases the intent of the publicly financed schools of art for children to reflect the multi-ethnic demographics of the city. Public community music schools of today, incorporate classes in all forms of art and are called "Culture schools". There is a long tradition of teaching and making music to lean on as a music teacher in Sweden. This paper tries to explore how these rights are expressed in the governing documents of the Culture school of Malmoe.
Potentiella virala zoonoser hos apor på svenska djurparker år 2008
This paper is a compilation of some of the important viral zoonosis that can be passed from apes and simians (simian and prosimian) to man. Viral zoonoses are viral diseases that can be passed from animals to humans. The paper will also provide a better insight of the risks workers and visitors to the zoo can be exposed to. The viruses that this paper is focused on is herpes Bvirus, simian T-lymphotropic virus type 1 (STLV), simian immunodeficiency virus (SIV), Ebola virus, Marburg virus, yellowfever virus, monkeypoxvirus and hepatitis B virus. The choice of viruses is based on how infectious they are and how pathogenic they are.
Nedskärningar eller anpassningar? Nyanlända elevers
The purpose of this study was to illustrate how cuts as a result of the economic crisis in 2008-2013 affected the newcomers' situation and the possibilities to reach the requirements for knowledge, based on the area manager, principals' and teachers' perspectives.The material we used for the study was made up of semi-structured interviews. We interviewed a psychologist, an area manager, principals and teachers. Most of the interviews were face to face and were recorded on a Dictaphone which we later transcribed and analyzed. During the process, we focused on the following aspects: acceptance and introduction support for new pupils, local opportunities and work material opportunities, school organization and employment structure, and reaction in the form of protests and demonstrations on restructuring the affected schools as a result of the cuts.The result that has emerged is that the teachers' main problem was the large increase in workload. The supervisors took no account whatsoever of protests and demonstrations organized in the affected area.
Större svartbagge Upis ceramboides i norra Hälsingland : förekomst, substratkrav och effekter av skogsbrukets naturvårdsåtgärder
Many wood living insects are considered threatened by modern forestry due to the reduction in amount of dead wood. During the last decade various methods have been used to enhance the quantity of dead wood in managed forests. However little is known how and if these methods are aiding saproxylic insects. The threatened tenebrionid beetle, Upis ceramboides, is already extinct in southern Sweden. It develops in white rotted dead birch (Betula spp) and requires sun-exposed sites.
Populationsstruktur och genetisk analys av exteriöra egenskaper hos svensk ardenner :
The purposes of this study were to estimate genetic and phenotypic parameters for conformation traits in Swedish Ardenner, a heavy draught horse, and to investigate the inbreeding status of the population. Additionally, a breeding scheme proposal was created, based on the results achieved in the study.
The data studied were obtained from the Swedish Horse Board and from the Swedish Ardenner Association. The data included 1632 three-year-old horses, mainly mares, and 356 stallions, judged between 1986 and 2005 at conformation shows. The traits studied were type, head-neck-body, legs, walk and trot at hand, total score and height at withers.
Mångkulturell bibliotekariekompetens - En litteraturstudie och intervjuer med bibliotekarier och chefer vid Malmö stadsbibliotek.
The title of this Master´s thesis is Multicultural librarian competence - a literature study and interwievs with librarians and managers in Malmö Public Library.Every fifth Swede is born abroad or has at least one parent who are. The migration flows of today reach out longer, there are more efficent ways of communication and travel. This has made previously ethnic homogeneous Populations as the swedish more and more hetergeneous. Library services to inmigrant users started out as a specially directed activities. The political view of migration has changed over the years and the current perspective is the one of mutual integration and cultural diversity.
Oralt intag av grönt te och dess effekt på uppkomsten av UV-inducerad hudrodnad, erythema solare ? En systematisk litteraturöversikt
Sahlgrenska Academyat University of GothenburgDepartment of Internal Medicine and Clinical NutritionAbstractTitle: Oral intake of green tea and its effect on the appearance of UV-induced erythema, erythema solare ? A systematic literature reviewAuthors: Ernita Antoni Mulliqi and Pernilla GustafssonSupervisor: Sofia KlingbergExaminer: Ingrid LarssonProgramme: Dietetics programme, 180/240 ECTSType of paper: Examination paper, 15 hpDate: April 10, 2013Background: UV irradiation of the skin can cause erythema, clinically called erythema solare. The condition can exert pain as well as discomfort and may in the long term lead to negative effects including skin cancer. Green tea contains catechins which are substances with anti-inflammatory effect that may have positive effects on the skin. The intake of green tea is believed to have a protective effect against UV irradiation, since green tea extracts in lotions in previous studies have shown to increase the skin tolerance level against UV irradiation.Objective: To examine the scientific basis and determine whether an oral intake of green tea has a protective effect against UV-induced erythema.Search strategy: Searches in the scientific databases PubMed and Scopus were made to find suitable articles.
Monitoring and pest control of Fruit flies in Thailand : new knowledge for integrated pest management
Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy Populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.
Predicting spawning bed erosion and longevity : a case study in tributaries to river Vindelälven, northern Sweden
Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish Populations, few studies have been conducted to evaluate the persistence of these constructions over time.
I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.
Om behovet av ett avrinningsområdesanpassat skogsbruk
The Swedish forest have about 100 000 km of watercourses and it?s an important structure in Swedish landscapes and catchments. In some of the watercourses lives spieces like the freshwater pearl mussel (Margaritifera margaritifera) and brown trout (Salmo trutta) which both are sensitive for inteference from the forestry. The new EU water framework directive has a goal that all surface water will have high or good ecological- and good chemical status at latest by the 22nd December of 2015.
The study has been made in the catchment of Håltjärnsbäcken and it is from a national perspective one of the most valuable streams in Sweden and which also have been included in a LIFE-project. The catchment is situated within the Eco-park of Malingsbo-Kloten and managed by Sveaskog AB.
Sametinget: en institutionell analys
The Saami, a Nordic indigenous people scattered over four countries, has for centuries been regarded as parts of the national Populations of the countries in which they live. During the 19th century saami demands for greater influence resulted en several changes, among them the founding of a Swedish Saami Council in 1993. The council became a popularly elected, representative institution with an agenda of its own, but also a public authority answerable to the government. The decision to attribute the council this twofold role was unusual and, from a certain point of view, even controversial: it makes it difficult to determine the location of the power to act in saami-related issues and the legitimacy to do so.This essay is about how the twofold role came into existence, what it leads to and how the seemingly contradictive duality is managed. It has an institutional approach with theories concerning institutions and etnicity as well as institutional change and handling of complicated and ambiguous demands.
Gremmeniella abietina-epidemin 2001 : har skogen återhämtat sig?
The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.
