Importance of epigenetics in animal breeding : genomic imprinting

ABSTRACTThe aim of this study was to give an overview of the evidence for genomic imprinting in livestock and other mammals as well as outline the potential use of gene imprinting in livestock breeding. Epigenetics is the mitotical and meiotical partial hereditary variation in genomic activity without any alterations of the DNA sequence. An example of epigenetic regulation is genomic imprinting where one allele?s expression differs depending on which parent it was inherited from. These parent-of-origin effects are currently overlooked in livestock production.

Att göra nya val - om nätverkets delaktighet i ungdomars väg ut ur ett missbruk

 The aim of this study was to examine how young people, who have been treated for their misuse and/or to learn to handle a parent's misuse, portrayed the network's implication in their wishes about improving their lives, to make new choices. The network included members of nuclear family, relatives, important persons at school/work and friends. The ?professional network? (therapists and social workers) also became a part in the young people's life during a period. The main issues of this study concerned differences in their experiences of the young persons´ network relationships in before, during and after completed treatment.

Bärförmågetillväxt i pålad friktionsjord

Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.

Skiktning och strukturell utveckling i unga naturlika skogsplanteringar: :

Multilayered woodland types are an important part of the urban forest. The knowledge how to establish and maintain such plantations are not as deep as other knowledge fields concerning forestry. Therefore this study has looked upon how to achieve multilayered structures in young nature-like woodland plantations. As a theoretical base for the study three different major knowledge culture have been studied that concerns the subject, ecology, forestry and landscape management/design. This three theoretical framework concludes that many natural processes strive in the opposite direction of multilayered structures in their youth.

Från gles skog och brokiga ungskogar till homogen produktionsskog : en skogshistorisk studie av Hällforsmarken under 1900-talet

The forest in the northern part of Sweden has changed dramatically during the last centuries. The forest has gone through a large-scale transformation, from it being only used locally for domestic purposes to becoming very important raw material for Sweden in the industrial age. The strategy by foresters during the second half of the 20th century has been to create pure production forests for commercial forestry. This has mainly succeeded and we have today homogenous production forests that give a high profit to the owners. The aim of the study is to compare the state of the forest in the former state forest Hällforsmarken in the years 1925 and 2000 and to interpret the changes which has taken place.

Whole grain wheat : effects of peeling and pearling on chemical composition, taste and colour

The EU-project HEALTHGRAIN has suggested a new definition for whole grain which allows a small part of the grain to be removed during processing. By removing the outer part or the grain the hygienic quality will increase but it is not clear how the taste and colour is affected. So therefore in this study three different debranning methods, peeling, pearling and polishing, which remove the outer parts of the grains have been used on common and durum wheat. The dietary fibre and ash content, as well as germination was analysed in untreated, peeled, pearled and polished grains. The decrease in dietary fibre and ash was higher in grains that had been pearled compared to those that had been peeled or polished.

Menstruationscykelns och p-pillers påverkan på den fysiska prestationsförmågan

Effects of Menstrual Cycle and Oral Contraceptives on Sport Performance During the menstrual cycle, there is a variation of the female steriod hormones estrogen and progestogen. These hormones has mainly reproduktive functions, but do also affect other physiological systems, which may have an influence on athletic performance. The use of oral contraceptives among female athletes matches the use among the general population. There is a concern among female athletes and there coaches weather oral contraceptives can affect the performance. The purpose of this litterature review is to determine the effect of the menstrual cycle and the use of oral contraceptives on athletic performance.

Foderbetor och kogödsel som substrat för biogasproduktion; anaerob mesofil samrötning i labbskala

One of Sweden?s sixteen national environmental objectives strives to decrease the impact on the climate. By 2020, green house gas emissions should be 40 % less compared to the levels of 1990 and a minimum of 50 % of the energy consumption should come from renewable energy sources. Because of this there is a great need of increasing the production of renewable energy. This is where biogas comes in as a competitive alternative.

Utveckling av en HBV/PULS-model med sammanfogade markfuktighets- och responsrutiner

Soil properties affect the chemical composition of soil water. When studying transport of chemical substances through a basin, it is therefore important to know from which soil layer the main part of the runoff is generated. The aim of this study is to develop an HBV/PULSE model with merged soil moisture and response routines, which generates good approximations of groundwater levels. It should be possible to extend the model to simulate transport of substances and take into account which soil layer the groundwater level is currently in. The hydrological version of HBV/PULSE is used since there is no need to account for pH or alcalinity at this stage.

Biodiversitet av evertebrater på vegetativa tak

In a city sometimes conflicts arise between either to save the species-rich vacant lots where many species thrive, or to build new buildings. Green roofs can then serve as a refuge for plants and animals that have had their natural habitat destroyed or diminished. Today we know too little about green roofs contribution to the biodiversity in the cities. We also know very little about how various types of vegetation on roof can increase biodiversity and its ability to attract different species.The aim with this study was to examine how different types of vegetation on the roofs affect the biodiversity of the invertebrate and how species-composition and number of individuals differ between the roof- and groundlevel.This study has been carried out on Augustenborg Botanical Roof Gardens in Malmo, and in an area about 1.5 kilometers away from Augustenborg. Three different types of vegetation on the roof and ground floor were selected: sedum- ruderal and grass.

En validitetsstudie på beeptestet : avseende maximal aerob kapacitet för elitishockeyspelare

Introduction: This study aimed to investigate the validity and reliability of the 20m multistage shuttle run test (MST) for elite ice hockey players as a predictor of the maximal aerobic capacity and the how the result is affected by the players age, aerobic and anaerobic capacity, body composition and test surface. The purpose of this was to find out the potential of the 20-m shuttle run test as a measuringtool for the maximal aerobic capacity in frequent testing periods during the season. It is very interesting to be able to administer this easily because the competative phase of the season is very long compared to the pre-seasonal phase and earlier studies have shown that the aerobic capacity is being lowered during this competative phase of the season for elite icehockey players.Methods: 34 elite ice hockey players participated in this study (20.0±3.6 yrs, BMI 24.2±1.6 and VO2-max 58.0±4.8 ml O2?kg-1?min-1). During 3-5 days they underwent 2 MST tests (wood and rubber surface), treadmill running with VO2-max assessed with open-circuit technique, Wingate10% and FFM-assessment with underwater-technique.

Småskalig livsmedelsförsörjning av mjölk :

During the last year?s Swedish agriculture have had difficult times, with decreasing prices and at the same time increasing production costs, which has led to bad profitability and faith in the future. The dairies in Sweden have also had a rough time and there have been large rationalizations during the years. In the beginning of the 20th century there were almost 1700 diaries in the Swedish countryside. There has been a large technical development during the 20th century resulting in a decrease in diaries to only 46 in the whole country today. They are owned by 15 diary companies, of which 7 large and dominate on the market and the rest are small-scale companies. With this development the confidence and feeling for the diary companies also has decreased.

"Malmös nya miljardkomplex" : Om strategisk kommunikation och förankringsmetodik i ett mångkulturellt samhälle

In May 2010 the plans for Malmö?s new Concert Hall, Conference Centre and Hotel were announced publically. The purpose of this thesis was to present strategy for communication in order to gain approval for the new concert and conference center from the inhabitants inMalmö and to incorporate the use of it in their everyday life.Material from the receiver?s as well as the sender?s perspective has been collected from qualitative interviews. Through group interviews we have investigated the general consensus of the inhabitants of Malmö regarding the investment, placing, offered events, expectations as well as how they collected information.

Tillsyn av djur på bete : betydelsen av lockgiva och regelbundna tider

During natural conditions cattle live in large herds, which are divided into subgroups of 10-15 animals. Humans have held cattle for over 9000 years. Today we mostly have cows for milk and meat production during more or less intensive forms. Most of the Swedish cattle have the opportunity to graze during the summer time. This partly arises from the Swedish Animal Protection law which stipulates that cattle must have the option to be outside and graze, also partly because it makes it easier for the farmer.

Vildsvinsskador inom jordbruket : hur stora är förlusterna?

Problems with wild boars are increasing in Sweden and some people argue that the wild boar population must decrease. This is mostly the opinion by farmers, while the hunters want more wild boars in Sweden. Today the population is the strongest in the south of Sweden and in the eastern parts of the country. However the population is growing stronger in other parts of Sweden as well. The population origins from these areas where they escaped from pens around 1970.
