Rening av avloppsvatten efter skärprocess

ABB I-R Waterjet Systems combines the robotics and motion expertise of ABB Flexible Automation with high-pressure intensifier/pumping technology from Ingersoll-Rand to provide and continue to develop innovative waterjet cutting systems for global markets. The purpose of this assignment is to develop a process water purifier. The purifier should be applicable as an option to ABB I-R?s production cell Cutting-Box. At first hand the process water should be purified well enough to let out in the municipal sewage system, but the ultimate solution is purifying the process water to the range that recycling is possible. When investigating the different principle of purifying water, a research of different products and their manufactories was done. These different products were compared and the principle of filtration was the most applicable, as most of the products were designed for far larger applications. As the process water contains quite large amount of particles, it is necessary to perform the filtration in different steps. The process water purifier is therefore composed of a module of coarse filtration and one of micro filtration. In the module of coarse filtration the mainly amount of fibres and particles are eliminated. They are kept back in the container unit with the larger fragments and dumped with these when the container is emptied. In the module of micro filtration the filtration is performed in two steps. In the first step particles larger than 50?m are eliminated, in the second step the micro filter is setting the range of purifying, in this case 10?m.

Undersökning av deponerat ferrokromstoft : Utvärdering av ny behandlingsmetod

The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.

Pellets - en framtidsmarknad?

With higher prices for oil and increased focus on fossil fuels impact on the environment the heating sector are searching for alternative fuels. Pellets are a quite new product whose production has risen exponential in recent years. Today there are small-, medium-and large-scale users, where the large-scale consumers are the heating sector. The heating sector is mainly using oil to cover the increased demand during cold periods. The purpose of this study is to analyze the potential of pellets if it would replace thermal power plants oil and coal. The study will also analyze the economic impact a conversion would mean for a heating plant and if the pellet is a reasonable substitute. 2008 statistics from the Swedish district heating association were analyzed and a calculation was performed to determine how many tons of pellets is needed to replace coal and oil.

Marte meo - "Show me" sade Maria: En kvalitativ studie av Marte meo terapeutens upplevelser och yrkeserfarenheter av metoden inom socialt behandlingsarbete

This thesis puts focus on Maria Aarts method "Marte meo" (on one's own strength). With the video camera as a principal tool, the purpose of the method is to be a practical working tool to support developmental processes on specific target groups, for example parents and their children. The aim of the thesis was to describe Swedish Marte meo Therapists and Marte meo Supervisors personal- and working experiences of the method, which was introduced in Sweden year 1991. Central questions were: How does Marte meo Therapists describe the essence of the method, it's establishment, development, and future in Swedish social services and psychotherapeutic treatment work? Which are Marte meo Therapists opinions of the methods relation to general problems and issues within social services and psychotherapeutic treatment work, such as the anchorage of theory and practice and the general claim for more research in social services interventions? In order to achieve the aim of the thesis a qualitative study was performed containing semi structured interviews with three Marte meo Therapists (two of them also titled Marte meo Supervisors).

Steroid-responsiv meningit-arterit hos hund :

Steroid-responsive meningitis-arteritis (SRMA) is a common form of meningitis in dogs. The condition is immunopathological, but the etiology is not yet fully understood. The aim of this study was to compile facts about the disease from records of Swedish dogs. The owners were interviewed by telephone for follow up where it was possible. 15 dogs were included in the study. All of them were neurologically examined in the Small Animal Clinic at the Swedish University of Agricultural Sciences.

Vilka faktorer har betydelse för ett företags beslut att underkasta sig revision?

Since 1983 all Swedish companies are legally obliged to allow themselves to be audited. Recently the question of whether small companies should be subject to this or not has frequently been discussed. Many find it superfluous and think it ought to be abolished. In England small companies no longer have to be audited. However, in a study by Jill Collis it has been shown that a large number of companies choose to be audited although there is no obligation for them to do so.

Nervmobilisering som sjukgymnastisk behandlingsmetod

Background: Nerve mobilisation is a controversial subject which has undergone great development in recent decades. Nerve mobilisation is based on a concept of both examination and treatment of the nervous system. Purpose: To study nerve mobilisation as a treatment in physical therapy with emphasis on evidence regarding the method. Method: A literature review. The search was made through the databases: PubMed/Medline, Academic search, PEDro and CINAHL/webspirs.

Örter - en nisch? :

A tight economy and a keen competition force the Swedish agricultur to do a structural rationalization. The quantity of farmers is less but the units are growing. How to make money I think some kind of niche is necessary. In my examwork I have locked how to farm herbaceous plant and the marking of herb to feedstuff for horses. Today health food and alternative medicine are accepted to use and there is an increase in demand. The Swedish market for herbaceous plants to horses is small and the products are mostly imported. But there is a group of consumers who is willing to pay a higer price for Swedish cultivated herbs. The only way to find out which herbaceous plants I could cultivate is to make a test cultivate. I think that the market for herbaceous plants is growing.

Mötesplatser i små tätorter : funktion och gestaltning

This bachelor thesis in Landscape Architecture is about the planning and design of public spaces in small towns in Sweden. My opinion is that the small towns often are overlooked and my determination is to see if that is right. The purpose with this thesis in Landscape Architecture, with focus on a durable society is to find the central public places in small towns and evaluate their function. This thesis has a focus on good design of central public spaces, designed for the inhabitants of the small towns. A small town, which is the focus of this thesis, is defined to have 200-2000 inhabitants. The small towns, which often are built around industries or the railway, have since the nineteen seventies a problem with people leaving them for the cities in the urbanization. Currently there is also the opposite trend with people moving out from the cities, but to live on the country side, not in the small towns.

Behandling av hanhundar med deslorelin :

This article presents a survey of male dogs treated with the gonadotropin releasing hormone (GnRH) agonist deslorelin (Suprelorin®, Virbac) at three animal clinics in central Sweden. Filled-in questionnaires from 110 dogs were received. The paper also includes a review of existing litterature concerning reproduction in male dogs, focusing on endocrinology, the effects of gonadectomy and the GnRH agonist deslorelin. Continuous treatment with deslorelin produces infertility in male dogs. The pituitary is initially stimulated by deslorelin leading to a rise in luteinizing hormone (LH) and follicle stimulating hormone (FSH) secretion. As a consequence the testosterone levels also increase temporarily.
