This report is the result of a thesis work in Integrated Product Development, regarding hygienic features in dishwashers and especially disinfection by the use of steam.The thesis is performed at Electrolux Primary Development Dishcare in Stockholm and in collaboration with the Department of Machine Design at the Royal Institute of Technology.The targets of the thesis are to prove the advantages of a technology suitable to implement as a hygienic feature inside a dishwasher and to realize a functional prototype of a differentiated hygienic feature that does not exist on the market today.The process followed to perform the thesis is the process defined for Electrolux Primary Development.The technology chosen for development is disinfection by heating the water on the surface of the dishware, by the use of steam.A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in consideration when designing the prototype.The prototype consists of a pipe system provided with nozzles to eject the steam into the upper parts of the dishwasher. Tests of the final prototype show that thermal disinfection of water in a dedicated area of the tub can be reached within 9 minutes. The operation requires 0,17 liters of water and consumes 0.2kWh..

This report is a documentation of the workflow and the result of a project carried out by twostudents from the Royal Institute of Technology in collaboration with a company. The report isstructured in a chronological order and describes the methods and systems developed in theworkflow. The report shows how the project evolved from a study phase to the various proposals onthe concept solutions.The project aims to develop a systematic way of bonding two different kind of cardboard under fiveminutes. By conducting a general study about glue and its different forms it was possible to obtain abroad knowledge, which helped to choose the right substances to later use in testing on the differentcardboard materials in question. Glues's survey resulted in a list of different substances that wererelevant to the project.

Hemoglobin is an oxygen binding protein in erythrocytes. Hemoglobin is composed of four polypeptide chains. During the fetal stage the type of hemoglobin called fetal hemoglobin (HbF) dominates. After birth HbF is replaced by adult hemoglobin (HbA). HbF persists in concentrations less than 1%.

There are several ways to identify individuals with dry mouth, but there are few studies made in which the different methods have been compared with each other.The aim of this pilotstudy was to compare different methods for identifying individuals with dry mouth. Fifty individuals aged 50 to 75 years were included in this studie. These where randomly chosen among patients at the dental clinic at Kristianstad University College. Four different salivary measurements were conducted: 1) collection of unstimulated saliva, 2) collection of stimulated saliva, 3) the so called ?mirrortest?, and 4) analyse using cottonrolls.

The purpose of this study is to contribute to our knowledge about what methods? teachers say they use in the work with pupils? early reading acquisition, and how they evaluate the pupils´ reading development. I also like to find out what educational interventions teachers believe that pupils with reading difficulties need, and how they say they work to meet the needs of these pupils. The project is based on the following questions: What methods do teachers say they use in the work with pupils early reading acquisition? What extra resources do teachers consider that pupils with reading difficulties need? How do teachers evaluate children's reading development? In order to answer my questions, I've done qualitative interviews with three teachers, at two schools, in two medium-sized municipalities.

To succeed, and make money at your animal production you need to feed your animals with high quality fodder. Other condition to succeed is that you keep your production costs at a minimum. To be able to produce baled silage at a low cost it?s very important that the bales have a high density. Density is measured in kg dry matter (DM) per cubic meter. The purpose with this report was to learn more about making silage in round bales and to how much the bale density varies between different brands of round balers.

Företag som har ekonomiska problem går idag i konkurs. När man har inlett en konkurs uppstår ibland möjligheter för företagen. En av dessa möjligheter är att genomgå en företagsrekonstruktion. Detta är en möjlighet för företaget att under en begränsad tidsperiodsöka skydd mot sina borgenärer och få företaget lönsamt igen. En företagsrekonstruktion blir antingen lyckad, då lever företag vidare, eller misslyckad, då går företaget i konkurs.

Control and comparison of various cleaning methods on restaurants in Södra RoslagenThe purpose of this report is to find out and analyze the efficiency of cleaning methods in restaurant kitchens. The investigation was carried out through unannounced inspections at 89 restaurants in Södra Roslagen (municipality of Danderyd, Täby and Vaxholm). ATP-measuring was done on a plate, a knife, a bench surface and a cutting board. The ATP-method measured the amount of food residue on equipment and working surfaces after cleaning, with a luminometer and swabs. Restaurant staffs were asked to describe in detail how and when the last cleaning was carried out on the surface.

The background to the study is that within the next ten years about 50 new multi-purposeindoor arenas will be built. These are used for various events such as sports, concerts, etc. In order to achieve a high level of security in the case of danger alarm signals and alarmmessages must be heard well by the visitors. ÅF-Ingemansson wanted to show builders the importance of good speech perception and that it is not observed in arenas today. They conducted technical tests on two large multi purpose indoor arenas to develop parameters that affect speech perception in the arena.To get a subjective view of how these arenas are experienced a survey was created.

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

The purpose of this essay has been to investigate if the national test results, in the subject of Swedish B at upper secondary school, are affecting a student?s final grade in varied degree among different teachers. The purpose has also been to investigate if the assessment of these tests is equivalent among different teachers. This particular investigation showed that there are big differences between how teachers grade, in relation to achieved results on the national test. According to the Swedish National Agency for Education, the teacher should take all performance information available into consideration for each particular student.

Students at the School of Engineering at Jönköping University have on behalf of the swimming organization ?Nässjö Sim och Livräddningssällskap? conducted research on how to monitor and evaluate swimmers and swimming groups in a simple and efficient manner with a focus on usability and user friendliness. Since no system existed that could meet these requirements, the client had a desire to tailor and develop such a system. The purpose of this work was to develop a system that would work as a tool to be used by coaches and swimmers alike and allow them to eventually follow the development of swimmers and swimming groups. The organization also wanted to have the ability to create tests and exams, both for land and water training, register these in the system and in a structured way know which swimmers took and passed these.For this thesis, the following questions functioned as a framework for progress.UsabilityHow to design a usable system and what is required?SystemWhat type of system is best suited to meet the client's requirements and preferences?Competition resultsHow can one retrieve all the competition results for swimmers of Nässjö SLS?DatabaseWhat type of database is best suited to easily share data with an external existing database?Usability has been the main focus throughout the project.
