When rubber equipment in a milking system ages, physical and chemical deterioration occurs and cracks, crevices, as well as deposits of organic and inorganic material is formed on the surface. Bacterial colonization can accumulate, especially on ageing rubber equipment and if the cleaning procedure is not functioning properly. Formation of biofilm in milking equipment could in turn cause bacterial contamination of bulk tank milk. ATP bioluminescence is a fast and easy way to determine the hygienic status of a surface based on its ATP content, and results are given in relative light units (RLU). The method measures both bacterial contamination as well as residues from other organic material.

Man vill förkorta betongs bindetid dvs. den tid då betongytan kan behandlas så att betongytan blir slät efter gjutning. Det är en stor utmaning för företag som tillverkar fabriksbetong vintertid, eftersom bindetiden förlängs ju kallare klimatet är.Syftet med denna labboration var att visa hur Kalciumnitrart fungerar som bindetidsaccelerator i betong, och om Kalciumnitrart påverkar betongens fysikaliska egenskaper.  Följande faktorer har studerats för att se hur dessa faktorer påverkar betongens bindetid i kombination med användning av Kalciumnitrat.Betongens utgångstemperarturTyp av flyttillsatsmedel i betongenBetongens utgångskonsistensBetongens lagringsklimatÄven hitta rätt dosering för att denna produkt ska vara lönsamt att användas i praktiken.Alla underökningar har utförts hos Sika AB laboratorium. All data har noggrant undersökts och använts i Excel program för framtagning av tabeller och diagram.Resultaten/slutsats i underökningarna visade följande.Bindetiden kan förkortas med Kalciumnitrat utan att behöva riskera betongens fysikaliska egenskaper.

In industries today the demand for reading the state of industrial equipment and thus prevent machine breakdown, is increasing. The company HMS Industrial Networks AB has a product on the market, Netbiter EC350 that is used to read sensors and thus find out the condition of industrial equipment. By reporting scanned data to users through a cloud service, users can keep track of their equipment. When developing Netbiter EC350 a slot was made for a Bluetooth module to offer clients a wireless reading in future developments. In this project a prototype was made to show how this Bluetooth communication can be implemented. The goal of the project was to create a Bluetooth communication between a Bluetooth sensor and Netbiter EC350. A user interface was made to allow the user to read sensor values. The result of the project shows how a Bluetooth communication can be implemented to read sensors wireless and therefore it fulfills its purpose and goal.

Extensive cattle management was reintroduced in Sweden during the 1950´s and 60´s. Usually this term refers to suckler cows for meat production that is kept outdoors all year around. Suckler cow farms tend to become fewer but bigger over time. Still however most of the farms with beef cows are small. Extensive animal husbandry can lead to animals becoming shy which leads to difficulties when they are handled due to veterinary treatments, marking, transport etc.

Traditionally, mining has been performed mechanically with implementation ofyesterdays (and older) data. Several mining companies have started to useautonomous technology and robotics in the production areas although the harshmining environments make it unsuitable for today's electronic equipment. Despite allthe obstacles along the way of digitization, there seems to be no end in sight as thisdevelopment continues. This thesis focuses on what the mining industry is aiming forand why the mining companies are interested in these technologies. The actors of themining industry can be found to have a vision for the future mine, a production with ahigher degree of digitization and resemblances to a factory.

This thesis work has been carried out at the consultant company Pöyry Sweden AB in Norrköping, whom performs the task for E.ON heating Sweden AB, Händelöverket in Norrköping. The report shows methods to manufacture slurry consisting of fly ash and water. The slurry shall be pumped into several former oil storage rock shelters that E.ON has put into operation for the specific purpose. The ash mixture also develops hydrogen gas in contact with water.The work has aimed to produce different suggestions of methods and equipment that can be used for the objective. Mixing method and security issues were in centre while working with the suggestions.

This Thesis in Military Technology deals with experiences drawn from the forced introduction of Weapons Station 01, 2009. The work aims to identify the experiences regarding the forced procurement of military equipment to see how they can develop normal and fast procurement of equipment. The main conclusions of  this work, is to achieve greater capability and increase the military utility, are: -          Common objectives and priorities of stakeholders-          Response and joint types shall determine requirements for system-          Ensure an integrated project team also at lower levels-          Engage the integrated logistic support early in the materiel process-          Include Armed Forces staff as early as possible in the testing and validation-          Prioritize work to facilitate the rapid development of decision on use (BOA)-          Provide back up for increased redundancy in the mission area .

For an outdoor environment to function optimally as a playarea requires that it is flexible, that is, contains places and elements that give room for the imagination and for own interpetretations, and also that the children in some way can influence and change their surroundings. It is also important to have variety, both in the sense that the playground has a unique character that distinguishes it from other places, and that it allows many different games and activities. There should for example be room for both wild games of running and moving around where many children can participate, and calm corners to withdraw to for rest or quiet play. A good playground should surprise, challenge and encourage children to discover their surroundings. One way to achive this is to use plants and materials from nature, whose irregular forms and structures can become interesting elements to explore. Vegetation also gives sence-experiences of various kinds, materials like twigs and leafs to play with and a place to play house.

Rapporten beskriver arbetet med att ta fram en regulator för dosering av närsalter i en biologisk reningsanläggning. Anläggningen som renar vatten med mikroorganismer behöver extra tillsatser av kväve och fosfor för att effektiviteten ska vara så hög som möjligt. Det har visats att variationer av föroreningar i avloppsvattnet kräver olika mängder tillsatser av kväve och fosfor. En simuleringsmodell för anläggningen tas fram för att användas till en jämförelse mellan olika regulatorer. Simuleringar visar att man kan förbättra regleringen genom att använda sig av framkoppling av mängden föroreningar i inloppsvattnet..

To be a part of the future we have to make a profit, one way to improve the profit margin is by reducing the fixed costs. This paper discusses the financial results of equipment cooperatives in crop production. Through a case study of three farms in Södermanland, we have an example of how it can look today and how it could look tomorrow. The three farms are crop-producing farms with slightly different orientation. Jursta Gård, 155 hectares, and Djursnäs Säteri, 215 hectares, have grains crop and oilseed crops as the main crops, and Nibble Gård, 340 hectares, mostly have pasturelands and some grain crops.
