This report is written on the assignment by Nexans IKO Sweden AB in Grimsås which is a cable manufacturing company. Nexans IKO Sweden AB was in need of help to examine possibilities for saving energy by saving compressed air, in first place by using the compressed air more efficient. The task was to determine the present situation, making the airwipe stations more efficient by reducing the consumption of the compressed air and in turn save money. Even the aspects of the working environment were discussed as the noise levels from the pneumatic systems and engines are usually high. A schedule over the airflow in the factory and the inventory over current airwipessituation was made.

Gastric and intestinal disorders are common and costly human health problems worldwide. Helicobacter pylori are a gram-negative, pathogen bacteria and the most common cause of duodenal and gastric ulcer in the stomach the intestinal mucosa. Prolonged infection and colonization can lead to chronic gastritis and stomach cancer. H. pylori are present in the gastric and intestinal mucosa of half of the world population and a relation between infection and low socioeconomic status has been shown.

Burnt Spine-cap Sárcodon fuligíneovioláceus are one the most endangered mycorrhizal fungal species in Europe. They have their main distribution in Sweden. It form mycorrhiza with pine and dependent on limestone, which makes it connected to a rare environment. It has therefore been important to study the ecology of it further and to recognise the requirement it has on the environment more accurate and what it need to establish in a new area. In this study, 31 of 34 known sites in Sweden was visited and studied in field and their history analysed through aerial photographs.

The dry period is usually 6-8 weeks and in this period the basis of the performance in the following lactation is settled. In an average herd about 15% of the cows are dry (Marcussen & Krog Laursen, 2008). In many herd the dry cows are set aside, that means setting aside 15% of your herd, at the time when they are preparing for their next lactation. The recommendation for number of groups differs depending on country traditions or reasons for grouping. If you look at recommendation for feeding, some companies selling feeding equipment advocates one group throughout the dry period, but the number differs from one to three.

The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.

Valmet tillverkar och levererar kompletta system för energi, massa och pappersproduktion till kunder globalt. En enhet inom Valmet, Flash Drying & Baling Technology, levererar bland annat manuella avtrådningslinjer för avtrådning av massabalar som de distribuerar globalt.Examensarbetet har gått ut på att analysera arbetsmiljön för operatörerna vid Valmets avtrådningstransportörer och ta fram en produkt eller koncept som förbättrar säkerheten och ergonomin, samt framhäver Valmets varumärke.Med hjälp av fältstudier, intervjuer, marknadsundersökning, problemidentifiering samt funktionsanalyser och andra designmetodiska tekniker har projektet lett fram till ett koncept för säker hantering av massabalar mellan lager och avtrådningstransportör.Arbetet har lett fram till att denna transport/hanteringssäkring bäst sker vid avtrådningstransportörens kringutrustning, mer specifikt hos truckens klämaggregat. Projektet har lett till att ett klämaggregat har utformats för att förhindra ras av massabalar, på väg till och vid avlastning på avtrådningstransportören, men även för att framhäva Valmets varumärke. Konceptet har också visat sig ha potential kring hur själv trådklippningen kan gå till, vilket diskuteras i rapportens slut..

The purpose with our thesis is to understand and explain the advantages and disadvantages there is with the self scanning system. The advantages and disadvantages we will highlight from three different angels; the store management perspective, the staff perspective and the customer perspective. These three perspectives will together form an overall perspective over the advantages and disadvantages as the self scanning system has contributed with. Finally we will highlight the differences and resemblances we have found between the perspectives.Through a qualitative approach we have gathered data to our thesis. Furthermore we have based our theory chapter and our empirical chapter on the base of Grounded Theory.

Steam was used as a site preparation method to eliminate unwanted bilberry (Vaccinium myrtillus L.) in the boreal forest. The efficiency of steam to suppress bilberry was compared with prescribed burning and cutting the bilberry. Different combinations of steaming and/or cutting the bilberry were set up to investigate in which way steaming and cutting influenced the sprouting and regrowth of bilberry. The regrowth of the bilberry vegetation was monitored for 40 month. Steam was most efficient in suppressing bilberry.

Soapnuts have been used as a cleaning detergent and medicine since ancient times in different parts of Asia. Today soapnuts are sold as an environmentally friendly alternative to common washing detergents. The aim of this literary study is to give an answer to what it is in the soapnuts that makes them work as a washing detergent. The active component belongs to a group of components called saponins which are secondary metabolites with the purpose to protect the tree from pathogen attacks. Saponins are widely spread in the vegetable kingdom and some of the families and species are so rich in saponins that their names are influenced by this, for example Sapnindaceae and Sapindus which are mentioned in the beginning of this literary study.

In January 2007 the Öresund committy changed its statutes to become a more politically oriented lobby organization. This change can be interpreted as one part of a continuously evolving process where the Öresund region is emancipating itself from the national states in a multi-level European environment. By focusing on this latest development the thesis puts forward the importance of political institutions, as well as politicians and civil servants as actors in them, as crucial factors in the process where the region is gaining political power. The thesis shows how the political cross-border cooperation in the Öresund region is being institutionalized which affects its power relations to other levels in the multi-level system, predominantly the national states. In other words, there is a connection between power and institutionalization.The Öresund committee has by gaining better access to policymaking agendas on the national levels proven that the organizational change has already started to bear fruit.

Detta examensarbete har gjorts på uppdrag av Skanska Teknik med handledning av Johan Sjödin. Arbetets syfte var att jämföra olika limträförband, utförda av antingen spikningsplåtar eller WT-T skruvar, och komma fram till den bästa lösningen med hänsyn till bärförmåga, kostnad och utförandetid. I ett projekt har de spikningsplåtar, som används vid limträförband, börjat rosta under extremt fuktiga förhållanden fastän spikningsplåtarna är rostfria enligt tillverkaren. En fördel med WT-T skruvar är att de är gömda inne i träet och på så sätt inte i direkt kontakt med den aggressiva miljön, men även skyddad mot brand. Andra fördelar med WT-T är att utförandetiden är kort och kostnaden är lägre än spikningsplåtsalternativet.

Bacteria are a problem that occurs naturally in dishwashers when the dish stands there dirty for an extended period of time. To get rid of the unpleasant smell that the bacteria is causing, the most common solution is to run a regular washingcycle which can cause problems for the environmentally-conscious consumers since this causes unnecessary energy waste and emissions of chemicals in the washwater. To solve the problem in a more environmentally-friendly way by directly attacking the bacteria with an appropriate bacterialreductionmethod can therefore be an attractive feature in a dishwasher. There are many different ways to treat surfaces that have been exposed to the bacteria. Some high-profile methods are UV-radiation, microwaves and oxidant (ozone) that all three have had success in reducing bacteria in different contexts.

The development of defoaming additives is steadily progressing and there are therefore always new and improved additives on the market. Some modern additives provide the desired defoaming effects by themselves, in contrasts to previous additives that needed to be used in combination with other additives. The task of this bachelors thesis was to evaluate the possibility of using these improved defoaming additives, with the aim to find alternatives that give the system better defoaming attributes while, at the same time, using less of the primary products. The tests were carried out in the coating type Teknocryl Aqua Combi 2780. The coating is a waterborne air drying acrylat-latex/alkyd based coating that can be used for both single coat painting and primer.

The main project Dry preservation of source-separated organic household wastes involves a new technique for treatment of biowaste through drying. Investigations are going on to determine how the dried biowaste best can be used to close the natural circular flow of nutrients. The objective of this degree project is to determine if the dried biowaste can be used as a soil conditioner. By restoring the nutrients in the material to the ground, the natural circular flow is closed. A declaration of contents, including the nutrient levels, C/N ratio, pH and the electrical conductivity of the dried biowaste, was constructed and a germination test was done to make sure that the material did not inhibit sprouting.
