En kvalitativ utvärdering av det accelerometerbaserade hältdetektionssystemet ?Lameness Locator? :
Background: Evaluation of lameness in horses is traditionally performed by a veterinarian who subjectively evaluates the movements of the horse. Accordingly, lameness diagnosis varies with the veterinarian and circumstances for which the horse is examined. Research within the area has long tried to establish an objective and standardized method for lamenessevaluation in horses. Several methods have been shown to be reliable and are used regularly within research, for example measurement of forces between the hoof and ground, and measurement of movements with high speed cameras or accelerometers. However these methods require considerable preparation, standardization, and expensive equipment as well as produce large amounts of data that are incomprehensible for the clinician.
Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos
Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.
Fysikdiskursen på Komvux : Betydelsen av student-lärarinteraktioner
This study draws upon the framework for analyzing the discourse of a science classroom introduced by Mortimer and Scott (2003). It has been used for many studies before on high school youths, but never on adults. Therefore, this study focuses on the interaction between teacher and students in an adult education on high school level in physics, and how students can change the classroom discourse. Observations took place in two different schools for adults, in four different teaching groups. The result was analyzed by pattern of interactions, communicative approach, teaching purpose, type of student questions and their effect on the classroom discourse.
Är fytoremediering en realistisk metod för att rena marken runt Glasriket på arsenik, kadmium och bly?
Phytoremediation is a technique using the ability of plants to absorb pollutants in their biomass from contaminated soils and remediate it. The plants are then harvested and the soil gets purified. This method is more environmental-friendly than the normally used methods for soil remediation. Glasriket in Småland is an area with large amount of pollutants including arsenic, cadmium and lead. This area must be cleaned from these metals because of the high threat to the environment ant the health of people who live here.
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.

Det allmännas skadeståndsansvar : Skadeståndsansvar för ideell skada enligt frihetsberövandelagen
BACKGROUND: Today?s societal changes, including high rate of change and increasing information flows, are increasing the demand on the individual mental capacity. It becomes increasingly difficult to analytically process all the different dilemmas and everyday decisions as individuals have a limited mental capacity available to make these decisions. Thus, it has been suggested that ego-depleted relies more heavily on intuition, which is less burdensome, when making decision. However little is known about to what extent intuitive decisions differ from analytic.

Nutritions betydelse för förbyggande av trycksår hos patienter över 65 år med genomgången höftfraktur
Trycksår är en komplikation hos patienter med höftfraktur som ofta tillskrivs sängläge men som kan uppstå vid olika långvariga inaktivitet och belastningstillstånd. Syftet med denna litteraturstudie var att undersöka eventuellt sambandet mellan nutrition och förebyggandet av trycksår hos patienter över 65 år med genomgången höftfraktur. En systematisk databassökning har skett i Pubmed och Cinahl. Denna studie genomfördes för att söka relevanta vetenskapliga artiklar och sju artiklar selekterades. Författarna fann att olika näringsämnen framförallt serumalbumin, arginin, zink, vitamin C kan påverka sårläkningsprocessen.
Kartläggning av skidinstruktörers hälsostatus : Generellt förekommande skador inom detta yrke
Good physical, psychological and social health is pursued both at work and at home. There is no current research into the health of ski instructors despite the physically demanding nature of skiing and high injury rate. The purpose of this study is to map out ski instructors physical and psychological health and see if there are common injuries amongst them. This study is a descriptive and correlating study including a survey of ten questions with self reported data from the instructors. Five ski schools from Sweden participated in the study and 86 surveys got sent out to the ski school directors.The result from this study shows that ski instructor´s physical, physiological, well being at work, stress level and self efficacy is good.
Men när sitter ni och läser alla böckerna? En intervjuundersökning av bibliotekariers syn på skönlitterära kunskaper
The aim of this thesis is to study librarians attitudes towards fiction and reading. I have examined librarians fiction reading habits and how they handle the expectations that users may have regarding their knowledge in fiction literature. There have been many studies concerning the librarians information literacy. This work explores librarians competence in fiction literature. The primary question posted in this thesis is: What kind of fiction are librarians reading and how do they feel that they can correspond to the users expectations? The data collection is based on literature on the subject and qualitative interviews with eight librarians from different kinds of libraries.
Förluster i olika ensileringssystem
In Sweden the climate makes it impossible to feed fresh herbage to cattle during many months of the year. During periods when preserved forage must be supplied it is important that this forage is stored in such a way that high quality is retained, both nutritionally and hygienically.
Furthermore, it is essential that losses occurring when handling and storing the forage are kept as low as possible. This study compares storage in tower silos, bunker silos, big bags and bales,estimating dry matter losses as well as losses in metabolizable energy and crude protein that occur during storage. The results show that tower silos, bunker silos and big bags, the systems with the
largest amount of forage and a long feed out period involve larger losses than bales, which are fed out immediately after being opened. As the feed out rate influences the losses, tower silos and bunker silos should be used during the period of the year when the feed out rate is as high as
possible, i.e.
??Finns det ett samband mellan graden av periodiseringar och inflationsjusterade skattade framtida rörelseresultat? : - Empirisk studie av den europeiska aktiemarknaden.
In line with Sloan (1996) but on European data (STOXX 600) we are investigating whether stock prices reflect information about future earnings contained in the accrual and cash flow components. The extent to which current earnings performance persists into the future earnings performance is shown to depend on the relative magnitudes of the cash and accrual components of current earnings. Moreover, we still find a significant positive excess return (Jensen?s alpha and size-adjusted return) by replicating Sloans (1996) hedge portfolio by taking a long position in the stock of firms reporting relatively low levels of accruals and a short position in the stock of firms reporting relatively high levels of accruals. However, we find no evidence of negative excess returns for companies with relatively high accruals, this somewhat lower the total excess returns for all the portfolios.
Biblioteket är till för användarna. En studie av folkbibliotekariers syn på bibliotekarieetik
The main purpose of this master thesis is to explore a selection of Swedish librarians view of professional ethics. The latest master thesis written on the subject was published in 1997, which concluded that the Swedish public librarians had a poor awareness concerning professional ethics. We wanted to investigate if something had changed. We interviewed six librarians from five public libraries, asking them questions concerning ethical guidelines, responsibility, censorship and selection, pressure from lobbyists, and ethical problems relating to Internet. The answers we got gave the impression of a divided profession, and the librarian?s awareness of professional ethics can hardly be said to have been improved since 1997.
