Turbiditet i dricksvatten: mätningar i Luleå kommuns
distributionssystem
Turbiditet är ett mått på partikelinnehåll i dricksvatten samt ett sätt att beskriva vattenkvaliteten. Vattentäkten i Gäddvik, Luleå kommun, har periodvis hög turbiditet. Syftet med examensarbetet är att utreda orsaker till turbiditet i dricksvatten, från Gäddviks vattentäkt till konsumenter i Luleå kommun. Målet är att ge svar på vilken typ av partiklar som orsakar turbiditen. Analyser utfördes före och efter filtrering av dricksvatten.
Positiv särbehandling - diskriminering eller ett nödvändigt led i jämställdhetsarbetet?
To achieve the goals that the government has put in place for equal opportunities in the labour market, the Swedish law is divided into two separate regulatory frameworks. One is positive action to promote equal opportunities and the other is the prohibition of sexual discrimination. Since males, despite the measures taken so far, still have a great advantage on the labour market, the law concerning equal opportunities has an exception from the prohibition of sexual discrimination, whose purpose is to promote the progress of equal opportunities, also known as preferential treatment. The regulations concerning preferential treatment allow the employer to hire a less qualified person from an underrepresented gender in spite of the presence of higher qualified applicants of the overrepresented gender. The purpose of this paper is to investigate the meaning and the application of preferential treatment as well as to give an insight to the argumentation around its application.
Simulering av översvämningar i Nedre Dalälven
Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.
Skulden och skammen. : Närvaron av skuld och skam i missbruksbehandling av kvinnor.
The purpose of this study is to examine the personnel?s perspective on how the emotions shame and guilt are present in the treatment of female addicts on an LVM institution. Three questions have been designed to meet the objective: How do they work in the treatment with guilt and shame, how important is it to work with these feelings and what significance does genders have in relation to shame, guilt and treatment? A qualitative approach and techniques have been used to obtain the result. The study's theoretical starting point consists of three themes: gender theory, labeling theory and a theoretical approach to the concepts of guilt and shame.
Hellre sjuk och mager än frisk och fet : En litteraturbaserad studie av kvinnors upplevelser under behandlingen för anorexia nervosa
BackgroundAnorexia nervosa is a growing problem in society and it is most common among women. It is a complex disease that affects both the mental and the physical health. The disease expresses itself differently from person to person, therefore, treatment should be individualized. Nurses need to gain insight into how patients feel about the treatment in order to understand their experience. Previous studies use statistical research to evaluate treatment.
Simulering av COD-fraktioner i en aktivslamanläggning vid en sulfatmassafabrik
This thesis work was made for Södra Cell Mörrums bruk in Blekinge. The purpose of the work was to develop a computer model in the simulation program Extend for the removal and balance of organic oxygen consuming substances, measured as COD (Chemical Oxygen Demand), in the new biological treatment plant in the mill. The plant produces two different pulp products, TCF- (Totally Chlorine Free) pulp and ECF- (Elementary Chlorine Free) pulp, for sale. The different bleaching procedures affect the characteristic of the wastewater and thus the effectiveness of the biological treatment plant.In the model that was developed the COD in the wastewater was divided into five different COD-fractions: soluble easily degradable (SS), soluble hardly degradable (SR), soluble inert (SI), particulate inert (XI) and particulate biomass (XB). To create the model FlowMac? was used as a base.

Två frivårdskontors syn på den procentuella skillnaden, vad gäller kontraktvårdsdomar
The aim of this paper is to spread some light over contract treatment from the perspective of the District Courts, Social Services and Probation Services, and understand the reason for local variation of the number of people sentenced to contractual treatment.Essential questions asked in this paper are; What advantages and disadvantages are known by the cooperating parties regarding contract treatment in comparison to prison? What parameters are considered when the cooperating parties decide upon contract treatment? What impact does the shared responsibility of cost have? What do the respondents think is the reason for the local variation?In order to answer the essential questions a qualitative and descriptive method has been used to highlight the main question of our study; What is the reason for the local variation in number of contract treatment sentences in Halmstad and Ystads district courts?The paper shows that the local variation between the Probation Services districts is dependent on the conditions to propose a contract treatment. In Halmstad it is not conditioned for the Probation Services to have a responsibility agreement with the Social Services to the same extent as for the Probation Services in Ystad..
Finngruvan - Uppföljning av vattenkvalitet, analys avavrinning och recipienter i området efter gruvdrift
This thesis raises the problem with acid mine drainage around the closed mine Finngruvan.The purpose of the investigation was to compare metal content in surface water in the areaand its catchments between year 2010 and 2003, also to make calculation of specific runoffand metal load, furthermore determine the recipients in the area. Surface water samplingwhere preformed at the same place as 2003 and also at a few other places of interest. Adigital elevation file were used in GIS to calculate the area of the watersheds in the region,observations in the field where also made. The collected data were used to make comparisons,calculations and conclusions. The result showed that the surface water 2010 had somewhatlower metal concentrations.
Som att ha ett osynligt koppel på sig : Intervjustudie med tre patienter med erfarenhet av utskrivning från substitutionsbehandling mot opiatmissbruk
Aims: To examine how patients with experience of being involuntarily discharged from medication-assisted treatment with methadone or buprenorphine have coped with the consequences following the discharge. The study also aim to examine how the patients cope with the stigma related to their abuse of heroin and how they manage to cope with the rules regarding themedication-assisted treatment. Method: Three patients with experience of involuntary discharge from medication-assisted treatment have been interviewed. All were heroin abusing men living in Stockholm. The interviewees were recruited through the Swedish Drug Users Union and through a shelter for homeless people with drug problems.
Development of Liquid Cooling for PCs
In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.
Utvärdering av akupunktur som behandling vid ryggömhet hos häst : en pilotstudie
Acupuncture has been used for thousands of years in China. Written documents concerning veterinary acupuncture has been found dated around 650 B.C. Acupuncture has gained greater acceptance in the western world the last decades and many countries have established their own veterinary acupuncture organizations.
Many studies report good results after acupuncture treatment and back pain in horses is considered a good indication for acupuncture treatment. In studies published, the results are subjectively evaluated. To get a qualitative, scientific evaluation of acupuncture treatment, objective measurements, control groups and statistical analysis are needed.
This pilot study presents a case where acupuncture has been used for treatment in a horse that was diagnosed with back pain.
Det kan vara farligt att ligga lågt - om stadsplanering inför stigande vattennivåer : Exempel från Göteborg, Kristianstad och Arvika
In this study is being examined how cities can be planned in the face of rising water levels and extreme weather, due to the changing climate. The starting point has been to investigate how the problems can be tackled and how the positive sides of water in the city can be strengthened, and synergy effects and greater sustainability be achieved thereby. The method has been literature studies and case studies containing interviews and visits. Göteborg, Kristianstad and Arvika have been studied for discussions and ideas about adaptation. Today, building near water is very popular which brings both advantages and disadvantages.
En korrelationell studie om beröringsundvikande, hierarkier och kränkning bland intagna vid en sluten kriminalvårdsanstalt
The aim of this investigation was to assess if there was a correlation between touch avoidance and hierarchical position, perceived degradation, number of years spent in jail and age amongst men at a correctional institution. In addition, a possible correlation between hierarchical position and the amount of perceived degrading treatment was also explored. In the collection of the data a questionnaire containing 27 open and closed answer alternatives was utilized. A multiple regressional analysis was conducted to find possible correlations between touch avoidance and the other underlying variables. Also an independent t-test explored the possible effects of the control variables: place of birth and girlfriend.
De sökte substitutionsbehandling-vad skiljde dem åt? : Jämförelse i bakgrundsfaktorer mellan opiat- och opioidberoende utifrån ASI-intervjuer
Through changes in the code of statutes, SOSFS 2009:27 (M), opioid addicts are excluded since March 1 2010 from possibilities to be accepted for substitution treatment. Opiate addicts are solitary admitted for substitution treatment from that date. Opioid addicts are excluded admission for treatment regardless of the fact that they fulfil the ICD-10 diagnosis F.11.2, i.e. opioid/opiate addictive criteria. The alteration in the statutes was carried out in reference to the fact that evidence for this kind of treatment intended for opioid addicts was missing.Both groups i.e.
