Vattenkvalitet och risker vid ändrat intag för vattenförsörjning i Västerås

Water is the most essential resource for life. In cases where drinking water is processed from surface water it is important to ensure the raw water is of good quality, and is suitable for processing through the water treatment plant.The drinking water for Västerås is sourced from Västeråsfjärden, in the western side of Lake Mälaren. The city itself is home to marinas, ports, a Wastewater treatment plant, the Svartån outlet, sewage pumping stations and stormwater outlets. Because of the negative effects these activities have on surface water quality, Mälarenergi AB is interested in relocating the raw water intake point to Granfjärden, 10 km east of Västeråsfjärden. At Granfjärden the intake point would be less exposed to the activities in Västerås, and could be placed at a greater depth, resulting in better water quality.In this Master?s thesis the water quality and the pollution risks at Västeråsfjärden and Granfjärden sites are compared.

Miljöeffekter vid ändrad ytbehandling på ITT Water & Wastewater

ITT Water & Wastewater (före detta ITT Flygt) tittar på att eventuellt genomföra en förbättring av ytbehandlingen av deras pumpar för att eliminera de rostangrepp pumparna utsätts för idag. Examensarbetets uppgift är här att analysera och beskriva miljöeffekterna av de nya ytbehandlingsmetoderna som företaget undersöker.Målet med studien är att få fram ett underlag och en rekommendation om vilken ytbehandlingsmetod företaget bör välja ur miljösynpunkt.De olika metoder som studerats är:? Järnfosfatering + ED-lackering? Zinkmanganfosfatering + ED-lackering? Oxsilan + ED-lackeringDessa metoder har jämförts med nollalternativet, vilket innebär att samma metod som tillämpas idag fortsätter att användas.Miljöeffekterna som studerats för de olika metoderna är:? utsläpp till luft och vatten? avfall? energiAv de tre nya metoderna samt nollalternativet är Oxsilan följt av ED-lackering det alternativ som ger minst påverkan på miljön. Metoden har inga utsläpp av flyktiga organiska ämnen till luft, inget farligt avfall bildas och det avfall som ändå bildas är litet. Metoden har även lägre energiåtgång än de andra studerade metoderna.2008:Nr 2 Teknik.

Fibromyalgi: sjukgymnastiska och närliggande behandlingsmetoder - en litteraturstudie

The cause of fibromyalgia has long been unknown but recent studies has shown that disturbance in the central pain modulation may be the cause. The aim of the study was to examine what kind of physiotherapy and close related treatment methods in the treatment of fibromyalgia there are and to determine their evidence. Articles were obtained by searching through the databases PubMed, Academic Search, AMED/Webspirs, CINAHL/webspirs and PEDro for articles published from 1994 and ten years forward. The study was based on thirty articles that met the criteria for inclusion. To assess the quality of the clinical studies the SBU?s evaluation model was used.

Rening av lakvatten vid deponin Degermyran i Skellefteå kommun : Utvärdering av nuvarande reningseffekt och simulering av mängden bildat lakvatten under 2000-talets klimatförändringar

At Degermyran landfill, situated in the municipal Skellefteå, a leachate treatment system was installed in 2005. One of the aims of this study was to investigate how well the treatment system works by using data from chemical measurements made on the leachate before and after treatment. Further this study had the purpose of investigating how the predicted climate changes of the 21st century will affect the amount of leachate generated at Degermyran by using a modified version of Thornthwaites water balance model. The treatment system has the ability of reducing manganese by 90 %, nitrogen by 73 % och TOC by 79 %. By the turn of this century the amount of precipitation that percolates the waste at Degermyran will be between 254 and 298 mm, depending on the amount of greenhouse gases that will be released in the future to come.

Lakvattenrening och kontroll vid deponier : granskning och sammanställning

If not purified leachate from landfills would cause damages on the environment. At most landfills in Sweden local treatment of leachate is achieved, at the rest the leachate is transported to sewertreatment. While no comprehensive legal provisions for discharge exist in Sweden there is a difference in discharges between the installations for landfill. If no comprehensive legal provisions is produced guidance must improve.Treatment of leachate and self monitoring system at fifteen installations in Sweden has been studied and compared. A study of literature about different treatment solutions has also been performed.

Programverksamhet i Kriminalvården : ur ett klientperspektiv

The purpose of this study was to look at how clients, in the Swedish criminal justice, experience their involvement in treatment programs. The spotlight in the study was to examine which helpful and unhelpful factors are involved in a treatment process, in the view of individual experiences. The study is based on a qualitative method, with interviews as an instrument for collection of data.The result is summarized in three fields; is it possible to show vulnerable, the therapist and the meaning of the program. The result is based on interviews with six informants; five of them have been partaking in treatment programs in prison and one in the probation office. The study shows that partaking in treatment programs in prison is combined with problems in aspect of the different roles criminals play in prison.

Skillnader i vatten- och avloppshantering inom EU : En jämförelse mellan Slovakien och Sverige

The management of water resources and waste water varies between the countries of the EU. For many years, a large part of the water in Europe has been contaminated by, among other things, insufficiently treated waste water and emissions from agriculture. The EU Water Framework Directive 2000/60/EC and the Urban Waste Water Directive 91/271/EEC are intended to harmonize fresh-water management and waste water management within the whole EU, aiming at safeguarding drinking water of good quality and a high quality of all water within the EU today and in the future. There are however some problems concerning the waste-water directive. One problem is the huge investment needed in Slovakia to fulfil the demands of the waste-water directive for waste-water management in larger communities (with more than 2000 inhabitants).

Kartläggning av källor till organiska föroreningar i avloppsvatten från svenska hushåll

At this point seamen have a lot of tasks of administrative character, beyond the traditional tasks aboard a ship. Due to the new conventions that are formed by IMO, more requirements are added which often lead to time consuming administrative tasks and documentation that should be spent on activities which are contributing to the ships safety. The issue has been observed by IMO that has through BIMCO done a study with the aim to identify and reduce administrative burdens at sea.The primary aim of this study is to find out if safety officers aboard Swedish ferries consider that SOLAS Chapter III, 8.3 och 19.5 regulations are administrative burdens, restricted to muster lists and documentation of training aboard the ship.The secondary questions to the study are if it is possible to remove, combine or change the documents and how much time can be saved by doing this. The question about timesaving could not be answered, because the values were scattered and could not be used for further investigation. The observed values were accumulated by a survey and the result indicated that safety officers did not experience the two regulations as administrative burdens.

Terapival vid behandling av lunginflammation hos kalv : en enkätundersökning

The purpose of this study was to investigate the kind of treatment strategies used by Swedish Veterinarians with cattle practice when treating calves with symptoms of pneumonia. A questionnaire, consisting of seven questions, was sent to one hundred veterinarians who have had practice with cattle and are employed by the Swedish Board of Agriculture. The survey was answered by a total of 73% of the Veterinarians. Of the respondents, 73 % use Penicillins as their first choice of drug for treating calves with symptoms of pneumonia, and as their second choice 64 % use Tetracycline. Supplementary treatment such as NSAID (non-steroidal anti-inflammatory drugs) and/or SAID (steroid anti-inflammatory drugs) are used by 97.5 % of the respondents.

Sjuksköterskors kunskap om smärta och smärtbehandling : En enkätstudie

Knowledge regarding pain and pain treatment is an essential part within nursing that a nurse is responsible for. Earlier studies have shown that lack of that kind of knowledge often results in inadequate treatment for pain. The purpose with the study was to describe nurses? knowledge regarding pain and pain treatment at a medical unit in a hospital in central Sweden, and to see if there was a distinction in knowledge related to professional experience. Data was collected through a questionnaire with questions referring to pain (6 questions) and pain treatment (6 questions).

Skolprestationer räknas! : Studie om hur ungdomars skolsituation verkar ha påverkats av multisystemisk terapi

The purpose of this study was to describe the school situation of adolescents who were subject to multisystemic therapy in Sweden, and also if a change could be measured after treatment. Factors that preceded the need for treament were also investigated. The sample consisted of 83 adolescents, boys (65 %) and girls (35 %), with an average age of 14 years. The method used was a secondary data analysis using pre-treatment- and post-treatment data collected from a 7-month follow-up conducted by Lunds Universitet. Results showed that the adolescents were low in school performance and high in truancy at pre-treatment.

Samtalsterapi på vårdcentral ? varför, hur och för vem?

Approximately one third of all patients in primary care have a psychosocial component to their illness that requires adequate professional treatment. However, primary care is insufficiently prepared for these patients. The aim of this case-study was to evaluate a pilot project in primary care offering psychotherapy as a treatment alternative. The data collected includes 1) data from 352 referred patients regarding demographics, diagnosis, treatment duration and pre- and post health status, 2) a patient-satisfaction questionnaire and 3) interviews with six therapists and five medical doctors. The treated patients improved significantly and showed a high degree of satisfaction.

Interdependence between seed age and aerated steam treatment intensities

Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.
