Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

The piglet mortality rates have become a major issue in today?s pig production. While other production traits such as number of born piglets or produced piglets per sow have been improved, the mortality rate has escalated. High mortality rates before weaning does not only affect the economy but must also be looked at as both an animal welfare problem and an ethical issue. The background to this problem has been addressed many times, and its salvation has also been addressed by breeding.

Syfte och frågeställningarSyftet med denna studie var att undersöka vilka fysiologiska effekter sex veckors högintensiv intervallträning (HIIT) på löpband med hyperoxi (>20,94  % syre) samt med normoxi (normal rumsluft) hade under kontrollerade former. De frågeställningar som hjälpte att besvara syftet var: (1) Hur förändras VO2max efter sex veckors högintensiv träning? (2) Hur förändras prestationen efter sex veckors högintensiv träning? (3) Hur påverkas löpekonomin av sex veckors HIIT? (4) Vilka fysiologiska effekter gav hyperoxiträning? MetodI studien deltog initialt åtta manliga vältränade löpare varav fem stycken fullföljde studien.

FP delades in i test- och kontrollgrupp och studien var utformat som en single-blind.

Background: Folate is a water - soluble vitamin necessary for normal DNA synthesis among  other mechanisms. Folate deficiency can cause megaloblastic anemia resulting from abnormal erythrocyte d evelopment. At the Department of Clinical Chemistry, Linköping, analysis of folate is performed with Siemens ADVIA Centaur® XP which uses an immunochemical method with chemiluminimetric detection. Currently, the assay is conducted on serum, is poured off and frozen after 48 h and treated with light protection because folate is considered to be light sensitive.Methods: This study tested lithium heparin plasma for analysis of folate with Siemens ADVIA Centaur® XP with the aim to be able to perform a package of analyzes in anemia investigation from the same collection tube. Furthermore, the stability of folate was studied for up to 168 h and examined regarding light sensitivity.Results: Statistically significant higher values were obtained in the analysis of folate in lithium heparin plasma than folate in serum (p < 0,001).

When the local authorities establish a plan for land use planning, they have to judge if the influence on the environment could be of such a grade that they have to make a special Environmental Impact Assessment (EIA), following national laws and EU-directives. The laws for the process in Sweden is set by the Swedish Parliament, with advisory given by the central government authority, the National Board of Housing, Building and Planning, Boverket. For EU, the laws is set by the European Parliament and the Council. The laws and directions for this process have been changed for Sweden in recent years, and the aim of this study was to compare the contents of three different Environmental Impact Assess¬ments to see if there has been any change in appearances and content in later years, as well as to see if different municipalities and authors have effect on the EIAs. According to different studies some of the EIA done are without insufficient focus on main environmental issues in the EIA, or even that some information is missing.

During 2008 we experienced an expansion of large scale investments in foreign farmland. This increasing trend has become a political hot-spot, but there is not much research available within the field. Due to a lack of research it remains a vital task to outline the potential effects of this trend. Drawing on existing ideas from some of the main actors within the field, The Food and Agriculture Organization of the United Nations (FAO), The World Bank, International Food Policy Research Institute (IFPRI) and the latest G8 summit on agriculture, four main purposes are set out for this paper. First, to outline some of the underlying mechanisms behind the trend is considered crucial for the understanding of the nature of these investments.

Road design with focus to safety has been extensively developed in last decades in Nordic and some other EU countries with the main aim to achieve a decrease in a number of accidents and fatalities on the roads. These countries gained many valuable experiences, but they had to sacrifice great effort, expenses, and time to reach the present art-of-state. The purpose of the Master?s Thesis is to review some design approaches with focus to safety and discuss the general way that they may be applied. The Master?s Thesis studies safety in three levels: (i) general - design standards, national safety policies and road hierarchy; (ii) local authority and road administrator; and (iii) three specific safety countermeasures - junctions, pedestrian crossings and traffic calming.

ABSTRACT: Commercial swab transport systems are used for collection and transporting of fecal and other microbiological samples. This system must maintain viability and contribute to survival of microorganisms during transport to the laboratory. Four swab transport systems have been compared, eSwab, ?- Transwab and fecalSwab, all three with flocked swabs, and Copan Venturi Transystem with rayon swabs. The study followed the recommendations from the Clinical Laboratory Standard Institute; document M40-A for recovery of Samonella, Shigella, Yersinia and Neisseria gonorrhoeae after storage for 0, 6, 24, 48 and 72 h at room- (22-25°C) and refrigerated (2-8ºC) temperature.

This case study examined what impact the neurological disorder Asperger?s syndrome has on the line of reasoning about religion and spirituality. Also, the question of whether the four informants showed any tendency to use the cognitive tools calledtheory of mind (ToM), existential theory of mind (EToM) and hypersensitive agency detection device (HADD) or not was put forth. From the interviews five themes were extracted: a stereoscopical view upon the world, thoughts on physical causality, prayer used as one-way communication, spiritual agency and intentionality, as well as existential and social questions. These themes were subsequently matched with theories on ToM, EToM and HADD.

Under de senaste åren har en ny trend inom spelindustrin uppstått då en stor del av spelen har gåtttillbaka till de tvådimensionella miljöerna som var vanligare i tv-spelens barndom, detta tack vareatt mobiltelefoner och deras spel har tagit allt större plats på marknaden och de är oftatvådimensionella på grund av sin begränsade hårdvara. De tvådimensionella spelen har enligttradition inte haft någon dynamisk ljussättning, utan de har bestått utav färdig grafik medförutbestämda intensiteter vilket gör att spelen kan se platta ut.Men inom andra områden av spelindustrin, framförallt tredimensionella spel, har utvecklingen avdynamiska ljussättningsmetoder kommit långt. Problemet med dessa metoder är att de kräverobjektens normaler, vilka normalt inte finns tillgängligt i tvådimensionella bilder.Idag är mobiltelefonerna kraftfulla och klarar av mycket tyngre beräkningar än vad de gjorde förbara några år sedan. Därför undersökte vi möjligheten att implementera dynamisk ljussättning i etttvådimensionellt spel på androidbaserade mobiltelefoner. För att genomföra detta krävdes också attvi undersökte metoder för att generera normaler för tvådimensionell grafik.För att ett fullständigt spel skulle kunna skapas så implementerades också saker somkollisionshantering, artificiell intelligens och procedurell generering av banor..

The objective of the essay was to identify the nursing care required by a dog suffering from heat stroke and how to educate and advice the owners how to start treating their dog and prevent the condition from occurring in the first place. The essay is based on a literature study. Several databases were searched for scientific research to try find answers to the issues. Keywords concerning the subject were used and mixed in different combinations to sort out the suitable studies. The results of the study indicate that the dog should be cooled by the owner directly after detection. The most crucial issue is to reduce the body temperature as quickly as possible or the morbidity will worsen.

This master of science thesis is focusing on how the fault handling on hardware connected toa control unit on a Scania vehicle is working. To the hardware counts buttons levers, sensorsand CAN. The work has been concentrated upon how the fault handling is working and if it ispossible to find any new fault modes.The control unit that has been studied is called the Coordinator and is the core in Scanias threenetworks of control units. The Coordinators work is to transmit messages between the threenetworks and to process signals from buttons, levers and sensors. The values is then usedinternally or is sent to other control units on the CAN networks.

The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.

This thesis has focused on the possibility to use a satellite image method developed by Metria Mijöanalys to identify stands that are wrongly registered in Holmen Skogs database. The method is only intended for identifying stand with poor descriptions in Holmen?s database that needs to be updated and not for updating the stand information. The study area is located several km west of Hudiksvall on the borderline between Gävleborgs- och Västernorrlands län. The area is covered by a SPOT image from 2005. By which Metria Miljöanalys has made estimates of forest parameters for all stands in the area, and compared them with corresponding estimates according to the stand database.

A carnival can not be stopped! A design pedagogical study of children and norms In Basel, the only Protestant carnival in Europe takes place. The carnival is called Fasnacht. For three days, there is a wild and uninhibited play with tradition, crossing borders and social criticism.The aim of this thesis is to expand the understanding of the concept of the carnival, and how to use it for an educational purpose. Three children from Basel have been involved in an workshop where they designed and talked about norms and power structures through the carnivalesque principle. The study is based on the questions: How can you use the carnival as a starting point for designing and talking about norms and power structures together with children? And; How can the design process support such a project? To spot this, I made arrangements for a design educational project.
