The main goal of this project was to develop some sort of a diverter for pipestransporting waste in a vacuum system. This unit was supposed to be both cheap andeasy to serve/exchange worn out parts. With a limited space to install the pipeexchanger, the challenge was to keep it as compact as possible without constructingbends with to small radius or to sharp angles as this would wear out the system a lotfaster than planned. The system was also supposed to be able to handle clothes andscrubs from hospitals. Having too much sharp edges or angles would tear the clothesapart.

The purpose of this study was to examine the differences between non-audited and audited sustainability reports and in that way indicate the significance of auditing to the contents of a sustainability report. The study was delimited to include three companies that create sustainability reports according to GRI guidelines, and also have changed from non-audited to audited reports.The study is an exploratory study where we started from companies that follow GRI's standard and who have changed from being non-assured to assured and certified. In order to examine any differences we have started out from corporate sustainability reports and with the basis of these latter gather those changes which may have occurred during the changeover. We therefore chose to conduct a literature review on each company's non-audited sustainability reports and compare them with each company's audited and certified sustainability reports. Furthermore our study has been made on the basis of an assessment model based on the concepts of materiality, completeness and comparability.The study showed that the audited sustainability reports in all companies were more focused and more detailed about the aspects GRI established for the performance indicators.

Today many industrial companies invest a lot of resources on research and development to resist the tough competition on the global market. This leads to a high risk game when the companies start many development projects, with uncertain outcome where some of the projects have to be terminated prematurely. The main purpose with this study is to identify factors, both internal and external, that influence the decision to terminate projects prematurely in Swedish development projects. Factors mentioned in the literature will be compared with case studies on three Swedish industrial companies to demonstrate the most important ones when taking such decisions. First a literature study was made to identify basic terms, a general project model and factors affecting the decision.

AimThe purpose of this study is to investigate whether there is scientific evidence that exercise and/or manual therapy can improve function, in terms of increased mobility and strength on shoulder impingement-like symptoms among athletes. Another aim is to investigate whether these interventions can reduce shoulder pain.MethodA systematic review was conducted in the databases PubMed, CINAHL, PEDro and Amed. A total of thirteen articles were selected for further review and compilation. They were then graded for level of evidence according to the PEDro scale and the Swedish Council on Technology Assessment (SBU).ResultsThe systematic review shows that there is strong scientific evidence that acupuncture and heat can reduce pain in athletes diagnosed with supraspinatus-tendiopathy. There is limited scientific evidence that exercise increases strength, limited scientific evidence that stretching increases mobility and insufficient scientific evidence that a combination of treatments, with both exercise and stretching, reduces pain and increases function in overhead athletes.ConclusionsExercise and manual therapy can reduce pain and/or improve function in terms of increased mobility and strength in athletes with shoulder impingement-like symptoms.

Inom Radiostyrd Bilsport tävlas det med ett antal olika klasser som drivs av 2-taktsförbränningsmotorer. Dessa blir mycket varma och måste kylas av. Det sker med hjälp av enkylfläns som är monterad ovanpå förbränningsrummet, och som kyls av fartvinden.HP Hobbyprodukter har frågat oss om vi kan hjälpa dem att ta fram en egen kylfläns åt dem.Eftersom det ofta förekommer ovarsam behandling i tävlingssammanhang, är det ett krav attkylflänsens ska tåla detta. Den måste även avleda värme från förbränningsrummet, motorblocketoch övriga motorkomponenter effektivt. Ett önskemål är att kylflänsen ska ha ett unikt utseende,så att den är lätt att känna igen ute på banan.Arbetet har inriktat sig på prototypnivå.

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..

The contact company, LRF Konsult, is a consulting firm specialized in areas of law, real estate, finance and taxation. Discussions on the subject of agricultural improvement in the area of Lean, has primarily been driven by the Royal Swedish Academy of Agriculture and Forestry, where LRF Konsult also participated. This thesis can be seen as a preliminary study of how Lean can work within agricultural enterprises.The thesis primarily focuses on the possibilities dairy farms have to improve operations. What practical benefits they can obtain through the implementation of Lean. And how an implementation could take place.By visits to two dairy companies, and through interviewing their respective business leaders, an image of the companies activity for improvement, in connection to this thesis was established.

Med dagens växande besättningar är det svårare att upptäcka brunst hos mjölkkor genom visuell observation. Detta leder till ekonomiska förluster, minskat genetiskt framsteg, högre inkalvningsålder och längre kalvningsintervall. För att underlätta brunstregistrering i besättningarna finns olika automatiska registreringar som kan upptäcka fysiologiska eller beteendemässiga förändringar som framträder hos kon vid brunst. Denna litteraturstudie sammanställer tre olika principer för brunstdetektering; visuell brunstdetektering, stegräknare och bestigningsdetektor, som kan vara antingen elektronisk eller manuell. Resultatet visar att stegräknare är den metod som upptäcker flest brunstperioder medan visuell observation ger minst felaktigt detekterade brunstperioder.

The design of the building envelope affects the energy consumption of a building. As the energy requirements for new buildings are becoming more demanding, the performance of the building envelope must be improved. Energy efficiency and durability are important attributes to consider.This report includes investigations of the building envelope, moisture and passive solar energy. It is based on the analysis of two different buildings with different designs. These buildings stand as reference for two of the companies who are working on a new, climate smart, residential area in Uppsala, Sweden.Studies and analyses on energy consumption and moisture transportation were made.

Safe retrieval of nutrients from human excreta to fertilize crops in order to gain adequate yields will increase food security and sustainability in agriculture areas with nutrient-poor fields. Safe and nutritious food will meet the dietary needs of the individual which promotes public health and the ability of an active life. Human excreta should be considered as a resource instead of being assumed as waste. Human faeces and urine is excellent fertilizers which may close the nutrient loop if utilized properly. However, sanitation of the excreta is required to prevent disease transmission by reducing the content of gastrointestinal pathogens such as bacteria, viruses and parasites. The objective of this study was to in small scale evaluate the sanitation in a combined liquid compost and urea treatment by monitor the inactivation of bacteria and viruses at the combination three start temperatures, 45, 40 and 35 °C, and three additions of urea, 0.5, 0.75 and 1 % and reference, 0 % urea addition.

The probiotic bacteria Lactobacillus reuteri DSM17938 was evaluated as a starter culture in cheese production, with the intention to produce a new interesting product within the functional food market. Growth and acidification rate in milk subjected to different heat treatments, as well as supplementation with growth promoting factors or support cultures was measured during controlled fermentations. The results showed that the weak proteolytic activity of L. reuteri could be compensated for by supplementation with 1% casamino acids or 5% MRS broth. Furthermore, a decrease in growth and acidification rate could be seen when using yoghurt culture or Lactobacillus delbrueckii as adjunct cultures.

Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.

The Swedish government has introduced a goal to reduce the energy intensity by 20% to the year 2020. To reach this goal actions need to be taken throughout the energy sector which includes residential and commercial buildings. This thesis considers the possibility to reduce the energy usage in a building located close to Uppsala. The analyzed building is a combined office, cafeteria and entrance and was completed about half a year before this project started. Therefore the measures presented for a more energy efficient building are presented as measures for future constructions.Simulations have been made in VIP-Energy, a dynamic energy calculation program.

The latest thing in the area of environmental building today is energy-plus-house. The idea behind the energy-plus-house is to create a house that produces more energy than it consumes. To accomplish this, the house uses renewable energy, in this particular case solar energy. With the help from a proper construction and thoughtfully projected installations you can achieve a surplus of energy. The surplus energy can then be sold to the surrounding buildings and thereby conduce to a financial profit for the household.

Fjärrvärmen utgör idag ungefär 12 % (48 TWh) av Sveriges totala energianvändning. Starka argument att använda fjärrvärme för att tillgodose bostäders och lokalers värmebehov är möjligheten att använda olika bränslen av skiftande pris och kvalitet, den goda verkningsgraden en centraliserad värmeanläggning erhåller samt fördelen med att kombinera produktionen av el och värme.Halmstad energi och miljö (HEM), förser Halmstad och närområdet med fjärrvärme och total mängd producerad energi uppgick 2009 till 596 GWh. Avfall och biobränsle utgör den största produktionsandelen men även industriell spillvärme samt mindre mängder olja och naturgas används för att framställa värme.Konkurrenssituationen för fjärrvärme är på många orter i det närmsta monopolistisk där en stor aktör äger hela marknaden. Det är viktigt att förbättra fjärrvärmesystemet för att i framtiden behålla dess konkurrenskraft. Följande rapport utreder och beskriver åtgärder för att göra ett redan befintligt fjärrvärmesystem mer effektivt.Utifrån möten med personal på HEM har tio punkter presenterats, vilka utvärderar olika delmoment i Halmstads fjärrvärmesystem.
