The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

The purpose of this study was to examine the relation between the Big Five personality traits Extraversion, Agreeableness and Neuroticism and the five conflict styles developed by Thomas-Kilmann: Accommodating, Avoiding, Compromising, Collaborating and Competing. The participants consisted of 128 students of the Linnaeus University in Växjö. A questionnaire consisting of two parts were used for this study: Part one consist of a personality-test developed from Lewis R. Goldberg?s Big-five scale, and part two where the participant is asked to fill out Thomas-Kilmanns conflict style test.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.

AimThe aim with this study was to acquire knowledge of mental training and if you can use it in the elementary school to increase in a short period of time the performance in a coordination test. Furthermore we wanted to investigate teachers understanding of the possibilities to perform this kind of training in the elementary school, and if there is support for this in the school regulation.MethodAs method we have used a combination of a literature pre-study, interview and at the end an experiment. Before the experiment and interviews could take place we studied literature about mental training to get a basic knowledge of the subject. The facts we learned from our pre-study and interviews gave us the base for our experiment. The experiment group included 23 pupils in a third class at school situated in Stockholm.

Syftet med vår uppsats var att undersöka spridningen av COSO-modellen i de svenska kommunerna, och vilka som är idébärarna av modellen. Även korrelationen mellan implementering av modellen och kommuners politiska, geografiska och storleksmässiga placering belyses.Då undersökningen bedrivs inom kommunal kontext har studien en institutionell ansats, och teorierna som används för att kartlägga spridningen av modellen i kommunerna är NPM, Institutionell teori och Spridningsteori. Undersökningen genomfördes med en webbaserad enkätundersökning, och vår målpopulation var Sveriges kommuner. Svarsfrekvensen på undersökningen blev 68%.Empirin analyserades med hjälp av Mann- Whitney test och Chi- Square test, med en signifikansnivå på 5%. Vårt resultat visar att det finns ett samband mellan spridningen av COSO och kommuners invånarantal.

This thesis has been performed for the company System Andersson as a part of the bachelors degree in information technology at the School of Engineering in Jönköping. The thesis is based on the development of an iPhone application.System Andersson has an application for Android that is being used for their MPS system (material and production control system). Their customers, however, have also showed interest in being able to use this application for iPhone.The students handle the subject of iOS developing, including the design of the application, the use of the development language Objective-C, the use of the scripting language of Json used for server connections and SQL.The primary goal with this thesis has been to improve the students knowledge in such subjects as application development for mobile platforms, in such areas as Xcode, which is the development platform that Apple uses and Objective-C, which is the development language being used. The result of this thesis is an almost fully functional iOS application, similar to the Android application with some functionality missing..

In this Master we have studied classification system and alternative arrangements of books in a public library. The public libraries in Sweden use the SAB classification system. This system was created nearly a hundred years ago in order to suit the librarians and the Swedish society at the time. Today many library users find the system difficult to understand. This and other factors have inspired a number of libraries to arrange books in an alternative and more user-friendly way.

PurposeThe purpose of this paper is to assess whether the overreaction found in ?Does the Stock Market Overreact?? by DeBondt and Thaler still persists today, and by equivalence test if a trading strategy based upon these assumptions would generate abnormal returns. MethodThe research has been carried out by studies of the stocks that for a prior period of one year has over or underperformed their benchmark. The stocks used in my study are all part of S&P500 index, and the period of study runs from three to five overlapping years over the last twenty years. ResultsMy tests indicate that the type of overreaction proposed by DeBondt & Thaler still is present, at least considering the stocks that during the formation period were winners..

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

Stroke är en av våra stora folksjukdomar. Cirka 30 000 personer insjuknar årligen i Sverige. Många av dessa personer får även droppfot. Peroneusstimulering började användas för första gången 1961. Tekniken är nu generellt känd som Funktionell Elektrisk Stimulering (FES).

Följande rapport behandlar konstruktionen av ett system som kontinuerligt ska analysera kvaliteten på vatten. Systemet är uppdelat i mätenheter som utför själva mätningen och en centraliserad server som man kan koppla upp sig mot för att övervaka/justera sina mätenheter.Uppdragsgivaren till projektet var forskare från IFM på Linköpings universitet. De hade sedan tidigare ett fungerande system för att analysera vatten kontinuerligt. Vår uppgift var att ersätta deras system med ett nytt, som var baserat på mindre och billigare hårdvara. Vi har visat att systemet går att implementera på den önskade hårdvaran.Rapporten skildrar även hur projektgruppen tog designbeslut under utvecklingsfasen.

Since 2005 all companies listed on a regulated stock exchange within the European Union are required to present their financial reports in accordance with International Financial Reporting Standards (IFRS) and International Accounting Standards (IAS). The purposes of these standards are to accomplish international harmonization of accounting rules to make financial reports more comparable. However, recent research has shown that some firms tend to use goodwill strategically in a business combination by manipulating the acquired assets and consciously allocate the intangible assets to goodwill to reduce the depreciation in the income and decrease costs. This phenomenon may reduce the comparability between financial reports and thus has an opposite effect on the purpose of IFRS and IAS.The aim of this study is to show how the companies involved in this study allocate goodwill strategically. Furthermore, the introduction of the new standards has contributed to that goodwill now is a subject for impairment test, therefore we want to show whether this affected the comparability of the companies in this study.An empirical study was conducted, based on interviews with four Swedish managers.

BackgroundDiathermy is the most commonly used surgical instrument in the surgical area today. Diathermy is used in surgery to cut and coagulate tissue. The use of diathermy releases chemical substances in to the environment in the form of diathermy smoke. Research shows that these chemical substances pose health risks to both staff and patient exposed to the smoke. To protect the interdisciplinary, perioperative team from the smoke, smoke evacuation systems can be used.ObjectiveThe purpose of the study is to highlight the work environment of the perioperative team when working with diathermy smoke.MethodThe study is meant to be implemented as an empirical descriptive sample survey.

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.
