This report presents a bachelor thesis by Erika Gustrén aimed to increase people?s interest for recycling and reusing by create new products of things that already exist in most people?s homes in the materials textile, plastic and paper. That would be a modern and innovative way to contribute to a better environment.The goal with this project was to create three cocktail dresses made of the same pattern and design and with the three chosen materials. The project did not have its base at a company, therefore an external mentor was chosen to help and support during the development of the project. My mentor was Kerstin Boulogner who is a fashion designer and one of the members of GKF (Gotländska Konsthantverkare och Formgivare) in Visby.The project began with an analysis of the chosen materials; textile, plastic and paper.

The resting area is the most important place in the barn for the dairy cow, sometimes called the heart of the free stall system. Inadequate design of the lying area, and lack of or poor quality of bedding materials may reduce the hygiene of the stall. Poor management regarding the cleanliness of the resting area may lead to poor animal hygiene and increased bacterial growth. This in turn will lead to increased risk for environmental mastitis as well as impairing milk quality through contamination with spores. In this literature study the most commonly used bedding materials; straw, sawdust, wood shavings, clean sand, recycled sand, peat and recycled manure solids, are compared to one another with regards to their ability to resist bacterial growth. Effects of adding hydrated lime to bedding materials have also been studied. Most bacteria need humidity and prefer a quite high water activity to be able to grow.

This is a study about how different digital instruments can be used in education for pupils with autism and intellectual disability. The questions formulated to research this chosen area was: ?What does teachers think about digital instruments and interactive teaching materials when it comes to benefits and disadvantages in the classroom?, ?In what ways is digital instruments used as teaching materials in the specific school context? and ?From a perspective of teaching and learning, what kind of problems and opportunities can be gained from using digital instruments and teaching materials?. To gather this information interviews was done with three specialist pedagogues working with the chosen group of pupils at three different schools. The material shows that the specialist pedagogues have positive attitudes towards working with digital instruments in this specific group of students..

The survey aims to shed light on traditional and contemporary bottom floor frames, their construction and different insulating materials; mineral wool, wood shavings and charcoal. The purpose is to analyze and discuss the similarities and differences as well as the pros and cons with a focus on the construction and the different insulating materials. The work has been limited to comparing two different wooden floor frames. The first one is based on a real floor frame from an older building, this example is presented as the traditional floor frame in this study and are from around 1940. The other floor frame is presented as a contemporary floor frame and is based on wood building type descriptions and literature.

When constructing an industrial- or hall building, the most common framework materials thatis used are wood, steel or concrete. Due to an assignment from Byggnadstekniska Byrån ABhas a document been created that makes it possible to investigate how the final costs is af-fected by gapes in between elements and which used foundation. And this with steel as thematerial. The purpose with this essay is to investigate which is the most well fitted materialwhen constructing an industrial- or hall building wood, steel or concrete. Information aboutthe different materials has been collected by litterateurs and by different internet pages.

When constructing a road the risk of emission of substances from the used materials to the surrounding environment has to be evaluated. The aim of this study is to present a proposal for how to evaluate the risk of contamination as a result of emission from the materials in a road construction. The study is based on literature studies, an inventory and a questionnaire that examines how experts in governmental agencies, industries and universities evaluate the risk of contamination. The inventory indicates that guidelines for evaluating the risk of emission from secondary materials in a road construction do not exist. The conclusions from the questionnaire are: that there is no common way to evaluate the risk of contamination as a result of emission from materials in the road construction, there is no uniform interpretation of the terms "minor" and "significant" risk of contamination and that the evaluation is subjective.

The thesis aims to compare differentpiping materials in heating systems interms of cost as well as to illustratethe impact of energy characteristics ofdifferent materials over its servicelife. The methods used for costcalculations regarding piping are alsoto be examined to highlight thedifferences between template basedcalculations and more carefully executedones. The work is delimited to discusspipes of steel, copper, plastics andcomposites. The aim is that the resultcan be compiled to illustrate the prosand cons of various materials whenevaluating investments.The main object of the survey is part ofa heating system in the office-block KVSommaren located in southern Stockholm.The configured piping system is designedwith the mentioned piping materials andis used to make up the data for flow andcost calculations. The differentmaterials are calculated in both aconventional manner with a supplementarycost for additional fittings and with amore accurate quantification of thecomponents.

The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.

This is a paper about the effects from smoldering fire on lithic objects from an archaeological view. The introduction gives the background to this paper, a short orientation to forest wildfires and why the work is limited to: flint, quartz, quartzite and slate. Material and methods describes the stone materials and the setup that was used in the temperature logged tests with three replications for each type of material. The fuel in the burnings was peat on a bottom of sand. Flint showed a more drastic effect from heat compared with the other materials. Slate seems to have greater tendencies to change to darker colour and luster at lower temperatures than the other materials.

This thesis is based on an investigation to find out in what way 40 Swedish public librarieskeep and preserve their library materials. The investigation is based on inquiries sent outto the libraries. It deals with the keeping of books with regard to external factors which havedestructive effects on library materials as well as the safety at the library buildings. It is, aswell, about the preserving work being done at the libraries.Comparisons are made with literature and accounts about preserving measures and recommendationsregarding appropriate environment in premises and depositories. The resultsshow great differences between the libraries as to the library environment, i.e.

The main purpose of this thesis has been to identify and discuss problems connected with the preservation of newspapers in Sweden. Another purpose was to see if the preservation of newspapers has been influenced by the fact that preservation studies in general concerns printed monographs and digital materials. This qualitative study is partly based upon interviews with four librarians experienced in working with newspapers and preservation. The thesis deals with cultural heritage in general and on a more specific level with newspapers where the following questions are dealt with: Why preserve? Who preserves? How to preserve? and What is preserved? Strategies used for preserving newspapers such as paper, microfilming and digitization are described as well as legal deposit, the Swedish microfilming programme and TIDEN, a digitization project of newspapers.

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

The aim of this study is to find information about what to do when riding arena footings are worn-out. Especially, the surface layer of riding arena footings is very interesting because of its importance of giving grip in every step for the horse, as well as shock ab-sorption. Generally, surface layers are containing several different parts in order to achieve desirable properties. These different parts can consist of organic material or in-organic material (mostly gravel). Gravel and many other materials in the top-layer are environmental friendly, and therefore, easy to get rid of.

Edsbyverken Office Furniture has over the past 100 years been producing delicate carpentry products, chairs and skiis, but more recently the focus has shifted to furniture for the modern office environment. With a wide selection of products and its characteristic neutral design, Edsbyverken has an extensive group of clients both in Sweden and internationally. The aim of my C level thesis project was to examine the materials Edsbyverken is currently using in order to develop new designs or product functions. Simultanesously, I also wanted to verify whether the method I developed for this project - to initially undertake a comprehensive study of the chosen materials and thereafter specialise on a certain product and target audience ? was effective and successful.
