Genetiska defekter hos nötkreatur :
Genetic defects are caused by mutations in major genes where the gene?s protein product has a large impact on the physiology of the animal. The synthesis of the protein can be altered by a change in the nucleotide sequence, which can lead to malformation and in many cases death.One of the main reasons of increase in many genetic defects is the use of few bulls in breeding programmes, causing a reduction of the genetic variation. Genetic defects cause suffering for the animal and influences the production by, for example, increased costs due to misscarriages, lost milk production and expenditure for medical treatment. Bovine Leukocyte Adhesion Deficiency (BLAD) and Complex Vertebral Malformation (CVM) are two genetic defects that were widespread before the causative mutation was discovered.

Population genetic analysis and breed assignment of three Swedish horse breeds
The genetic relationship between three Swedish horse breeds was investigated using microsatellite data from 144 loci in 30 horses. The North Swedish Trotter is believed to have been crossed with the Standardbred in the 1950?s to produce a faster trotter. If true, the North Swedish Trotter should be more alike the Standardbred than what the North Swedish Draught Horse is, from which they originate. This was investigated using F-statistics and Nei?s distance in GENEPOP and GENETIX and cluster assignment in STRUCTURE.
Genetic diversity of Roseroot (Rhodiola rosea L.) from Sweden, Greenland and Faroe Islands
Roseroot (R. rosea L.) has gained more attention the last years, mainly because of its phy-topharmacologic properties. Even though many reports in roseroot have been published, only a few articles are dealt with the genetic diversity. The Nordic Genetic Resource Center has collected Roseroot material from Sweden, Greenland and Faroe Islands under different expeditions. The samples were analysed to study the genetic diversity study.
Genetiska ultraljudsmarkörer : Hur bör information till blivande föräldrar i samband med rutinultraljudet hanteras?
Objective: The purpose of the study is to explore and illustrate how ultrasound midwives and medical specialist in obstetrics and gynecology believe the information given to parents about the genetic soft markers should be handled.Design: A quantitative questionnaire study with cross-sectional design. Participants: 44 ultrasound midwives and 37 medical specialists in obstetrics and gynecology.Findings: Most of the participants would like to inform before the ultrasound starts that they will be looking for genetic softmarkers during the ultrasound. Likewise the majority wanted to inform the parents about possible increases in the risk for chromosomal abnormalities based on findings on the routine ultrasound. There was a difference in frequency between those who responded that they would like to inform before the ultrasound that they will be looking for genetic softmarkers and those who responded that they believe the future parents wants information before the examination.Key conclusions: It could help health care professionals in their role as information providers if there were common recommendations for the information to be given to future parents about genetic softmarkers in connection with the routine ultrasound.
Förvildade husdjur : möjligheter och hot
Feral animal populations are distributed over many parts of the world and are often seen as a problem. Since they are a threat against other species, destroy farmlands and can spread dis-eases, they are often referred to as pests. Artificial selection has contributed to loss of genetic diversity in our domesticated animals. Feral animal populations are affected by natural selec-tion, which allows them to adapt to the environment. Their ability to adapt is a reason to see them as pests but can also be seen as an asset.
International and national genetic evaluation of beef cattle : validation of national genetic evaluation models
After a workshop in Kuopio held in June 2006, Interbull decided to go forward with the development of a system for beef international genetic evaluation and a three year project called Interbeef was launched in June 2007. The participating countries are so far limited to Europe and the only trait evaluated at present is adjusted weaning weight (weight at 200 days). The results from a first international genetic evaluation have been shared with the countries but are not yet official. The evaluation is based on data from purebred Charolais and Limousin. To achieve good estimates of proofs in an international context it is important that methods for data validation and model selection are implemented.
Läs- och skrivsvårigheter och alternativa verktyg i skolvardagen
The purpose of this study was to investigate how two students at intermediate level in reading and writing disabilities and two special education teachers perceive the use of assistive tools in school. The questions used to answer the purpose was how assistive tools are used based on students´ perceptions, the purposes for which assistive tools are used based on special education teachers´ perceptions, what opportunities and/or barriers pupils and special education teachers experiences with assistive tools and how it works when assistive tools are implemented based on students´ and special education teachers´ perceptions. Data were collected by interviews. The results show that the assistive tools are mainly used for writing assignments and to ?read-with-ears?, primarily to facilitate the learning process in the classroom.
Genetic variation in local Swedish sheep breeds
Sheep have played a very important part in rural history. In Sweden there were many kinds of
small native breeds, kept for their meat and fleece. Women cared for the flock that often had
very little to feed on during the cold and sometimes harsh winter months. This meant that
these sheep over time acquired special phenotypic properties depending on the environment
they lived in, and easily fed compared to modern breeds kept for meat. Most of these sheep
have since become extinct.
This is IT! : Lärares pedagogiska synsätt på användandet av IT-verktyg som medierande redskap i ett en-till-en klassrum
The use of laptops, interactive whiteboards and the Internet is step-by-step working it?s way into Swedish schools. The aim of this study is to investigate the attitudes of teachers towards using IT-related tools in their teaching. How are the tools given used as mediating tools, what new methods do the teachers find themselves discovering while using these, how do the teachers feel about digital teaching platforms and how do the IT-related tools affect students language progression? These are all questions that this study is meant to answer.
Förekomsten av den genetiska varianten laktapersistens hos neolitiska grupper från Öland : The contribution of the genetic variant Lactase persistence among Neolithic people from the Baltic island Öland in Sweden
This study deals with the contribution of the genetic variant lactase persistence among Neolithic people from the Baltic Island Öland. Skeletal remains from twelve individuals went through DNA sequencing in order to find the mutation that allows adult individuals to digest milk sugar. The twelve individuals were chosen from two different Neolithic sites, where the archaeological and isotopic data suggest that the individuals from Köpingsvik were hunters and gatherers and the individuals from Resmo were early farmers. The individuals with the genetic variant lactase persistence can be described with selection and genetic flow. Only five individuals produced results and the mutation was found in two of the subjects. All the individuals who were successfully sequenced came from Resmo, whereasno individuals from Köpingsvik yielded any results.
Att digitalisera skolan : Fördelar respektive nackdelar utifrån ett lärar- och skolpolitiskt perspektiv
The aim of this studie is to describe, analyse and understand the benefits and disadvantages with using digital tools in education. In my qualitative method three primary school teachers were interviewed about how digital tools should be used in educational purposes, also what benefits/disadvantages they could see with the investment of digital tools in their school. I also did observations in two classrooms and interviewed a school politican to get a wider perspective. The collected information identifies that some benefits of using digital tools is the contribution to a more equivalent education, more opportunites for cooperations and that fewer pupils have to struggle with their fine motor skills when producing a text. Some of the disadvantages with using the tools is that they breaks sometimes, it´s easy to get dependent and if something happens (like power outage) it´s unusual that schools have a good an action plan.
Arvets betydelse för mjölkkors beteende :
It becomes more important to consider different behaviour traits in the selection for dairy cows to be suitable in the production systems of today. The purpose of this investigation was to study the genetic background to behavioural traits and the heritabilities for temperament, rank order, aggressiveness, feeding behaviour and for learning behaviour. Moreover, the genetic correlations to other traits were studied. To be included in a breeding programme a trait needs to have enough genetic variation, a moderate to high heritability or to be correlated to another measurable trait. Behaviour is a quantitative trait affected by many genes and the environment.
Din sökning gav inga träffar : En undersökning om folkbibliotekspersonal och deras upplevelser vid sökning i bibliotekskatalogen
Today, one of the foremost tools used by the library staff is the library catalogue search tools. It has come to our understanding that some library staff are dissatisfied with how the search tools works. The aim of this study is to illuminate the library staff's negative experiences of the search tools, and to present a basis for future discussion and development. To our help we have used a quantitative survey which were sent to library staff that used one of the two largest integrated library systems in Sweden, BOOK-IT and Mikromarc. The questions regarded the library staff's perception of a number of features in the search tools.
Privatiseringen av de växtgenetiska allmänningarna : Konsekvenserna av regimkomplexet kring växtgenetiska resurser för bönders rättigheter och matsäkerhet
This thesis discusses the global regime complex concerning the management of plant genetic resources for food and agriculture, and how different regimes concerning these resources cooperate or stand in opposition to each other. Because of changes in US patent law and the establishment of TRIPS, patent claims over plant genetic resources has increased dramatically globally. This, amongst other things, in turn has lead to the development of CBD which in turn lead to the creation of access and benefit laws in many countries. To create a free flow of genetic resources for food and agriculture the ITPGRFA, with its multilateral system, were negotiated. The aim of this thesis is to investigate which consequences the regime complex concerning plant genetic resources for food and agriculture can have on the rights of small farmers, agricultural research and food security in the global South.
