The project has been performed in a close collaboration with Hörsam who works in the field of hearing technology. In a first meeting with the company, the Project group was showed a few existing storage boxes for hearing aids. The company thought they were unnecessarily large with plenty of unused space and wanted a new, smarter solution to be developed.The project began with user studies in which audiologists, maintenance technicians, future users and others were interviewed. The purpose was to obtain their views on today's storage boxes and to find out how well the users maintained their hearing aids. It proved to be a large lack of knowledge regarding the management of hearing aids within the users.

This thesis is performed in cooperation with Prodelox AB and JTI (Swedish Institute of Agricultural and Environmental Engineering). The purpose of the project is to generate and develop a WC-technique with a closet sewer that keeps a higher TS-substance than 1.5 %. The WC-technique is mainly directed towards permanent households in sparsely-populated areas and cabins. The goal is to generate concepts of toilets with an extremely low use of water in terms of flushing. The design should be appealing and touch more senses than only the visual.

Cultural objects may become wet by deliberate water Cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet Cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.

During the 20th century a significant proportion (about 15 %) of the peat-covered wetlands in Sweden were drained to improve forest productivity. Area wise, most of the forest drainage was done in northern Sweden, but relatively speaking a larger part of the wetlands have been drained in the southern parts of the country. Most often, the forest drainage resulted in increased forest growth, but failures were not unusual, and harmful effects, e.g. on species richness, have been a common cause for draining. Ditch Cleaning is necessary for maintaining the ditches in good condition.

Biogas is increasingly used for fuel in for example vehicles and it´s produced in a biogas processconsisting of the steps of pretreatment, digestion and gas Cleaning. The pretreatment is a method usedto increase the gas production and / or destroy pathogens. The digestion is the stage when anaerobicmicroorganisms convert bio-mass of a substrate to a raw gas containing about 65% of methane. Thegas Cleaning is used to increase the methane content to about 97% so the gas can be used for motors invehicles. The biogas part of the Ekeby sewage plant in Eskilstuna is using multiple substrates.

Mechanization of Swedish agriculture started in the beginning of the twentieth century, to be able to have more animals without raising the number of employers. The horse business has not by far kept up with these cost savings solutions. Cleaning out stables and feeding horses are the most time-consuming tasks in horse stables today. The most common way to clean out the stable is still by shovel and wheelbarrow. The clean out process can easily be mechanized through semi- permanently beds with movable walls between the boxes so that the litter can be removed by a tractor or a loader.

With an increased demand for biomass based energy and with development of better technique harvest biomass, new possibilities open up. With the possibility to combine traditional Cleaning of road?s right of way with biomass harvesting, the work of suppressing tree vegetation could become profitable or at least decrease the road maintenance cost. However, knowledge about productivity and profitability in mechanical biomass harvesting in roads? right of ways are still limited.

This study shows how to plan a pond with an ecosystem which although it will have turtles living in it will not need to be cared. I will also demonstrate how this pond would be designed to work in the natural landscape on Mallorca. The background to the study is that I am interested to investigate how plants that we in Sweden are using as indoor plants are growing in their natural landscape and how to build a land-scape with them. The study highlights different Cleaning-systems that can be used to clean a pond in a natural way. A comparison will be made between the conditions of an exterminated turtle-species which will live in this environment and a species that is easier to care for.

This thesis describes the work process and the results for the development of a newkind of ergonomic Cleaning mop, ranging from basic concept to a virtually productionready digital prototype. The project was made in cooperation with, Ömer Altun, whowas also the project supervisor, and whose plan it is to launch this new product onthe market in a foreseeable future. The mop is meant to be used by both professionalCleaning staff and ordinary home users. What makes this product unique is that it hasa movable center piece that simplifies the Cleaning under low furniture.The work began with the establishment of a product requirements specification andlater a study of similar products and existing functional models was conducted. Afterthese surveys the work began with refining the existing concepts in order to makethem more complete.

This report summarize a simple and efficient way to convert 2D into 3D designs. It explains the benefits of a 3D design compared with 2D, and how those benefits may be used.It will also give the reader a presentation of the company Clean Air Technologies, which for the most part constructs Cleaning facilities for power plants. How to create 3D-libraries for some of those facilities will be introduced in this composition.The collaboration with Clean Air Technologies has resulted in several 3D animated movies and rendered images. This has increased the quality of the companies offer presentations, which has made it easier for the prospective customer to get an improved overall image of the power plant design..

Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as Cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.

Root rot causes large economical losses for Swedish forestry. The spread of root rot can partly be prevented by treating the spruce stumps in thinnings. Late pre-commercial thinning (PCT) is one of the forestry measures where stump treatment is not used. Late PCT can be defined as: The act of Cleaning the stand with the aim of improving accessibility and sight within the stand, and so to increase the mean stem´s volume during the first conventional thinning. The aim of this study was to examine how late PCT is performed, its spatial extent and if it aids the spreading of root rot. The study was limited to encompass late PCT before first conventional thinnings in spruce stands in southern Sweden. Samples of spruce stumps were taken from four stands where late PTC had been carried out.

Chlorinated aliphatic hydrocarbons (CAH´s) were used widely within dry Cleaning facilities and for metal degreasing until their toxicity was discovered. PCE is still used as dry Cleaning liquid. Today CAH´s are found in soil environment at places where they have been used in the past. The CAH-concentration in trees growing on contaminated land has quite recently received attention as a cheap and effective way of assessing the extent of a CAH-contamination. The method has however, not been put into use in Sweden.The aim of the study has been to investigate whether the CAH-concentration in tree cores could be used to delineate the spread of CAH in a soil environment under Swedish conditions in different seasons.

This dissertation is performed at the request of Lagafors AB who develops and manufactures stationery and mobile hygiene solutions for companies in the food- processing industry. The objective of this dissertation is to develop and construct a new, cost efficient Cleaning station based on an innovative technology.The technique is based on serially connected dosing pumps which allow the customer to work with concentrated detergents. This leads to serious reduction in the clients use expenses. Two units have been developed with this technique, one that is stationary and one that is mobile.The dissertation has led to good results which resulted in the sale of the first stationary unit of the Lagafors CPU before the end of this dissertation. .

This thesis is about catastrophe tourism and the sustainability of the tourism in an environmental perspective. The purpose is to see if there is any interest for that kind of tourism and to see if the people who have an interest or curiosity of it thinks about the environment when they are traveling. A quantitative survey was made on the internet and people on Facebook, Resedagboken.se and Reseforum.se had the chance to answer it. There is an interest of catastrophe tourism and a few have been to catastrophe sites or would like to visit. The conclusion of the thesis is that there is a possibility of a sustainable catastrophe tourism because most of those who answered that they had or wanted to visit a catastrophe site also thought about the environment and Cleaning up after themselves..
