Earlier investigations showed that damages on timber from feeding rolls could be within the lower classes of damage according to VMRs classes. Knowledge about differences in productivity between kind types and aggressive types of feeding rolls is necessary because it should influence the question about damages on timber caused by different feeding rolls. In this study the production and timber damage in a harvesting head were evaluated at three levels of pressure (8, 10 and 14 MPa) on the feeding rolls, and with three different types of rolls. One type, the rubber cushioned steel plate roller had 10 mm studs and rubber damping, one ?middle? type made of solid steel with 14 mm studs, and one aggressive type, also made of solid steel with 18 mm studs.

The study focuses on the use of poetry in language teaching in the lower grades in the Swedish school. Poetry has a reputation of being an art form with such specific rules and structures that children and teachers think that it is something that they do not have the ability to work with.  The purpose of this study is to get an understanding of how poetry is used in educating children. My research is based on the following questions. To which extent is poetry being used in schools and how is it being used?Can you as a teacher see any effects on childrens language development by using poetry?As a part of my study I have met with and interviewed four different people, who in one way or another is involved in teaching children. Two working teachers in the lower grades, one pedagogical resource and one artist that work with teachers in reaching different goals through the help of aesthetic processes.

The two swedish unions, Akademikerförbundet SSR and Kommunal, have a majority of female participations who mainly work in the public services. The difference between the unions is that one of them only represents members with academic educations and the other has members with lower educations. The aim of this study was to compare the two unions according to the terms exit, voice and loyalty, but also participation and influence. There were 142 participants in this study and 8 participants were interviewed in a pre-study. The result of the study shows that voice is a strong predictor to wellbeing in work life.

Fantomsmärta är ett komplext fenomen som drabbar många patienter efter amputation av extremitet. Syftet var att utforska hur fantomsmärtor efter amputation av extremitet kan upplevas och lindras. Litteraturstudiens resultat utgörs av 15 vetenskapliga artiklar som presenteras i tre huvudteman vilka är fantomsmärtans komplexitet, lindring genom transkutan elektrisk nervstimulering och lindring genom rörelseterapi. Det har visat sig att upplevelsen av fantomsmärta medför en negativ påverkan för patienter efter amputation av extremitet. Olika behandlingsmetoder till exempel transkutan elektrisk nervstimulering och rörelseterapi har beprövats med varierande resultat.

Det finns idag ingen konsensus om den optimala rehabiliteringen efter en främrekorsbandsrekonstruktion, vi vet heller inte idag huruvida rehabiliteringen skaspecificeras efter parametrar som kön och ålder. Studien var en korrelerandetvärsnittsstudie med syfte att ta reda på om det förelåg någon skillnad i postoperativlårmuskelstyrka 4-7 månader efter en korsbandsrekonstruktion med avseende på kön,ålder, skada och typ av operativt ingrepp. Av de 330 aktuella försökspersonerna var detendast 74 personer som godkänt deltagande och uppfyllde kraven förinklusionskriterierna. Försökspersonerna testades i en isokinetisk dynamometer(Biodex)för maximal styrka(60gr/s) och uthållig styrka(180gr/s). Resultaten presenteradesgenom ett Limb Symmetry Index.

Children with cleft lip and palate (CLP) and children with specific language impairment (SLI) may be affected emotionally and psychosocially by their disorders. Thus, it is important to investigate the psychosocial risk factors that these children are exposed to. The aim of this study was to examine how parents assess the emotional and psychosocial well-being of children with CLP and children with SLI, and if the two parental groups differ in their assessments using the standardized instrument Child Behaviour Checklist (CBCL). Participants in the study were the parents of ten children with unilateral and bilateral CLP between ages 6;7-9;0 (mean age 7;5) and the parents of 13 children between ages 6;4-8;8 (mean age 7;3) who are attending preschools and schools for children with SLI. These parents were asked to complete the questionnaires CBCL and Child Health Questionnaire (CHQ). The children with CLP had lower scores than the children with SLI in all domains of the CBCL, indicating that these children with CLP had better emotional and psychosocial well-being.

During the last decade a new technique in animal breeding has developed called genomic selection. It is based on estimations of the effect from genetic markers on traits that are calculated in a reference population. By genotyping individuals, genomic breeding values can then be estimated without phenotypic observations. The aim of this essay is to investigate the response of genomic selection on breeding schemes for dairy cattle. The accuracy of the genomic breeding values is affected by the proportion of observations included in the validation set and how often the equation for estimating breeding values is reevaluated.

This study centres on learning to read and methods for teaching reading skills. The aim is to provide a survey of the concept reading skills and the methods developed on the basis of different theories and the methods preferred when teaching children in primary school and why. The study is based on interviews with eight teachers who are working on a dailybasis teaching Swedish in preschool class or lower primary school. The result of my study is that the majority of teachers do not use a specific method, but rather combine several different methods, thus adapting instruction to each individual pupil. .

The purpose of this study is to find datable interstadial sediments in the core area of the LateWeicheslian ice sheet extent. Based on geomorphological evidence, three coring sites wereidentified close to the Ultevis plateau in Norrbotten, northern Sweden. Sediment coring wascarried out in two pre-Late Weichselian stream channels and in a sediment basin. Stratigraphyfrom one of the sites, a 100 meter wide meltwater channel, was chosen for further analysis. Thestudied core was 5,93 m long and ended in a lower till unit.

The goal of this thesis is to design an attachment between a duct and a pod. A pod is what could be compared to an outboard engine for larger vessels. The pod is placed on the outside of the ship?s hull and can rotate 360 ?. A duct is a large steel ring that can be placed around the propeller on the pod to increasethe propulsion force of the ship in lower velocities.

Forest as an investment alternative has become more and more popular over the last few years. Between the years 2004 and 2007 increased the price level on forest land with 70 percent in Jämtland. In this thesis a comparison has been conducted between forest in Jämtland and an investment in the stock market. The risk in the two investment alternatives has been included in the comparison. The thesis includes two different studies between the two alternatives.

The purpose of this study was to investigate the presence of arterial insufficiency in patients undergoing CABG surgery and whether arterial insufficiency is a risk factor for postoperative wound infections in the harvesting leg. Patients who had CABG surgery were enrolled consecutively. A total of 144 patients participated in the study. During their hospital stay demographic data was recorded, as well as pre-, intra-, and postoperative tests and risk factors. The patients answered a questionnaire regarding postoperative wound infections 30 days after surgery patients answered a questionnaire regarding infections.

A growing population together with a change in food habits to a more diverse diet containing more animal products such as meat and milk makes the possibility to produce and sell products of cattle a growing market. And at the same time there is an ongoing debate about global warming, where raising cattle is questioned due to their high production of enteric methane. To be able to raise animals in a more environmental friendly way and at the same time improve productivity in a developing country such as Vietnam would be favorable. The use of feed additives with high electron affinity could decrease the methane production and at the same time improve the gross energy digested. Nitrate and Sulfur are both good electron acceptors, but due to its toxic effects the use of nitrate in feed has been neglected.

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.
