Demand and economic potential for working horses in Swedish municipalities
The aim of my study is to answer the question whether there is a potential for services by working horses in the Swedish municipalities. The Swedish University for Agricultural Sciences (SLU) and Swedish Farmers Union (LRF) has started a cooperation called Climate School (Klimatskolan), with the purpose to increase knowledge in environmental and climate related issues in context of agriculture. This Master thesis is in the framework of the Climate School.Global warming is a problem that gets much attention today. Global warming and climate change are two subjects that are very much in focus on the political agenda. The municipalities of Sweden have a big responsibility concerning environmental work and to develop their own environmental thinking.
Kroppsuppfattningen hos kvinnliga och manliga högskolestudenter. -En kvantitativ undersökning.
Introduction:A good work environment and good resources among district nurses? and general nurses? are important in the provision of good nursing care. For patient security it is also very important that resources and time are used in an appropriate way. A lot of time is spent on non-core activity, for example administration takes more and more time, which can result in feelings of stress.Aim:The aim was to describe how district nurses? and nurses? in primary care perceived their work environment, how their worktime content was distributed and if there was some connection between perceived work environment and the distribution of work time.Methods:A mapping of the content of the work was made in two parts.
Genomisk selektion inom köttraser
Genomic selection (GS) is used for selection of breeding animals of dairy cattle. GS is though not as extensively used within the beef industry. One reason for that is the low accuracy (rTI) of the breeding value that is of great importance for the final genetic gain. Causes to the low accuracy are high effective population size, a small reference population and a genetically differentiated population. There is however a market for genomic selection with High Density (HD) tests for beef cattle.
Hjärtfrekvens och kortisolkoncentration hos valpar under olika typer av valptest :
The aim of this study was to find possible relations between behaviour and physiology for puppies during different parts of a puppy test. This work deals mainly with the physiological part of the study. Thirtysix puppies, från five litters, were tested in a behaviour test where heart rate was measured and saliva samples were collected before and after each part in the test. Saliva and urine samples were analyzed for corisol concentration as an indicatior of stress. The tests were performed during two consecutive days in the breeders' home when the puppies were seven weeks old.
In addition, heart rate and cortisol levels were also measured in the bitch since we were interested in finding out if there were any relations between physiological levels in bitches and puppies.
Inträdes- och utträdesbarriärer : småföretagens rörlighet på den gotländska bankmarknaden
The main purpose of this study was to investigate which enter- and exit barriers that exist on the banking market for small enterprises located within the region of Gotland. The reason was to examine and identify which barriers that could affect the mobility among small enterprise bank customers on the bank market. To identify the barriers, the study was carried out partly by a quantitative survey with 33 small business owners respondents located at three different concentrated small enterprise areas within the region of Gotland. And partly by qualitative interviews that were conducted with two employees at Länsförsäkringar Gotland Bank.The result indicated that the enter barrier mostly depended on the aspect that business owners of small enterprises believed that bank switching were complicated. The business owners did also consider bank switching as time demanding.
När en patient flyttar : Patientens upplevelser inför förflyttning från högsäkerhetsenhet till annan vårdenhet
The aim of this essay is to create an understanding, of how teachers comprehend knowledge, grades and tests in a school context. It is important to get a grip of the different parts of the teacher?s reality. The test, the grades and knowledge are deeply connected as a part of a whole. The teachers view on knowledge can not be understood without asking about the practical parts of their work and understand how the different parts are dependent on each other.The main material consists of interviews with four teachers that work in a public mandatory school in the south suburbs of Stockholm.
Verbbenämning hos svenska barn i åldern 3;6 till 5;5 år : En studie av prestation på Action Naming Test
Verbbenämning innebär förmågan att benämna en bild utifrån den aktivitet som bilden illustrerar. I tidigare studier har det visat sig att barn tidigt i språkutvecklingen har svårare för verbbenämning än substantivbenämning (Gentner, 1982; Kauschke, Lee & Pae, 2007). Detta förklaras delvis av att verb är mer lingvistiskt komplexa än vad som är fallet för substantiv (Gentner & Boroditsky, 2001), samt att de är svårare att illustrera (Masterson, Druks & Gallienne, 2008). För att undersöka benämningsförmåga används oftast bildbenämningstest och för verb saknas ett svenskt test för barn. Föreliggande studie syftade till att undersöka verbbenämningsförmågan hos svenska barn samt att utröna om den svenska översättningen av Action Naming Test (ANT) är tillämplig på svenska barn.
Kvalitetssäkring av stordimensionella gjutgods : Produktion och kontroll av formgjutna komponenter
AbstractA continuous improvement of products and production is an important goal for a modern industrial company. A small engineering group located in Sweden came in touch with the authors of this report during the spring semester of 2014. The aim of this report is, as part of the group´s ambition of improvement, to analyse ways in which the quality of component casted parts can be verified. Non-destructive testing (NDT), and methods to use it for quality control, is the main focus of this report. However, fields such as material standards, component casting and quality engineering are analysed as well.
Mäns våld mot kvinnor i nära relationer : Straffrätt och jämställdhetspolitik
Syftet med studien var att ta reda på om det går att predicera medarbetares livstillfredsställelse, psykosociala välmående och upplevd relation till närmaste chef utifrån chefers emotionsperception och emotionsreglering. Detta gjordes genom att 38 chefer utförde ett datorbaserat emotionsperceptionstest samt besvarade Emotional Regulation Questionaire. Deras närmaste medarbetare bestående av totalt 213 stycken fick sedan besvara en enkät bestående av delar från Satisfaction With Life Scale, SF-1 och QPS Nordic. Studiens huvudresultat visade att generaliserat kan resultatet från emotionsperceptionstestet och det självrapporterade användandet av omvärdering av känslor hos chefer förklarar 28 % av skattningarna på Satisfaction With Life Scale hos medarbetarna. Resultaten diskuteras i termer av att chefer skapar en positiv atmosfär på arbetsplatsen, identifierar sociala problem och löser konflikter effektivare när de är skickliga på emotionsperception och omvärderar sina känslor..
Däck-mark Interaktion hos skogsmaskiner
The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

Furthermore, these forests exhibit very high environmental values, and they are an element in the traditional cultural landscape.
Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring
The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.
