Vidareutveckling av beräkningsmodell för reduktionsgrader och avkylningseffekter i luftade dammar

Rapporten behandlar arbetet med att förfina, utveckla och dokumentera en beräkningsmodell för simulering av biologisk nedbrytning och temperaturförhållanden i luftade dammar. En luftad damm är en enkel typ av biologisk rening där mikroorganismernas biologiska nedbrytningen av oganiskt material påskyndas genom att syre tillförs ? vanligen med hjälp av ytluftare.  Arbetet är ett examensarbete inom ramen för högskoleingenjörsutbildning i kemiteknik vid KTH och har utförts på uppdrag av ÅF Industry AB som har använt beräkningsmodellen sedan 1970-talet. Modellen togs fram med hjälp av tidigare forskning, data från befintliga anläggningar och nedbrytningsförsök utförda i laboratorieskala.I arbetet har ingått att sammanställa och dokumentera erfarenheter och bakgrund till de beräkningsformler och konstanter som används i modellen. Vissa förenklingar har gjorts genom att lösa ut parametrar ur ingående beräkningssamband och genom att avläsningar ur diagram och successiv anpassning har ersatts med beräkning från en kurvekvation.

Akustiskt åtgärdsprojekt av en rockmusikklubb där live-musik spelas. Vad kan en audionom bidra med?

Introduction: The number of hearing impairments in Sweden is increasing. The largest increase is seen in ages 25-44. There are reasons to believe that these impairments are noise induced. Leisure time noise is not controlled in the same manner that industrial noise is. An ongoing conflict between city council officials and rock club owners, musicians and music event organizers about sound levels at smaller live music clubs exceeding the national sound level restrictions created the need for an acoustic intervention project.

Lågstadiet och skolbiblioteket : En undersökning bland skolledare och lärare på lågstadieskolor i Malmö.

The current curriculum requires a well functioning school library and an active use of it. In junior school grades 1-3 the children primarily learn basic skills. Knowledge about libraries and how to use them and different media is part of these skills. Therefore my intention was to investigate how school libraries in junior schools look, how they are used in the training and how they could be used in junior school education. I focus on the pedagogic role of the school library and the library as information center.I begin by going through what the school law and the curriculum say - or do not say - about the use of the school library.

Metodfokus på Affekt; Hur känns det?

Evidence-based psychotherapeutic methods compete with each other, while meta-analysis have shown that variability due to different methods related to outcome is remarkably low. In this qualitative study six former patients were interviewed about experiences of method and technique in Affect-focused therapy, with a slight overweight towards unsatisfactory experiences. Responses were analysed and categorised in emergent themes. Methodological focus on affect showed to be a much appreciated, as well as insufficient, element. Alongside positive experiences or summaries of therapy, methodological frames were felt to be at times restrictive, even invalidating, as far as not allowing focus on what was felt to be the more predominant need.

Central Peripheries: speculation and strategy for a land less mentioned

As the contemporary discourse surrounding urbanism is almost exclusively focusing on aspects of density and traditional urban qualities, it entrenches notions of what constitutes a proper city and countryside. But beyond this urban-rural dichotomy is another highly contemporary landscape. A territory usually mentioned as sprawl, peri-urban, wasteland, edge city, etc. Although its existence is due to mobilization, telecommunications, globalization and other phenomena of modern life, it is a landscape without an own name or place in public awareness.This thesis provides a case study of how to map and intervene in such a landscape, specifically along the border between Malmö and Burlöv municipalities in southern Sweden. Its structure is composed of a sequence of three parts:1 Spatial Conditions:Divided up in the sections Network, Fringe and Void.

?Dubbelt uppdrag blev trippelt?: måluppfyllelse, värdegrund och? marknadsföring! : - En kvalitativ studie av musiklärarens utåtriktade verksamhet

My research interest in the upcoming paper is the increased need for promotion of schools. I. e. the individual school´s needs to be able to show its existence, in the huge flow and availability of information; schools and universities, study circles, streamed lectures on the Internet, public schools and private schools, different educational directions, et cetera. The schools? needs to market itself, make good PR and sell their pedagogical idea, and that has become increasingly important. My purpose is to clarify how music teachers, in the Swedish primary and secondary school, skills and competences are used in outreach activities within but also outside, the school premises.

Syns du inte så finns du inte. - En studie om irreguljära immigranter och socialtjänsten

Different studies have shown that somewhere between 10 000 and 75 000 persons live in Sweden as undocumented migrants. They are not entitled to basic human and social rights such as access to health care on the same basis as persons holding a residence permit in Sweden. Undocumented migrants are often exploited as workers in the informal economy and they are not allowed to organize in unions. The Swedish Social Services is by law bound to care for all people living in Sweden, though in reality undocumented migrants are excluded from benefits and efforts granted by the Social Services. Our aim with the study has been to investigate the situation of undocumented migrants in Sweden and in relation to Social Services.

Analys och förbättring av en mätenhet för laddning av elfordon

Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.

Hur ser behörighetskraven till yrkesutbildning ut i de olika läroplanerna?? Vad är tankarna bakom läroplanerna?? Hur kan kraven i utredningarna till läroplanerna ses i ljuset av perspektiv på kunskap?Metoden jag har använt mig av är en dokumentstudie och kunskapsbegreppet används somteoretiskt perspektiv.Studien börjar med en historisk utblick på yrkesutbildningar.

Förhållningssätt till elever i svårigheter i en skola för alla : En studie om hur några pedagoger och specialpedagoger talar om och tänker om elever i svårigheter

This study aims to increase the understanding of how some teachers and special education teachers work and relate to pupils with difficulties, and in which way they use guiding documents in their daily work. Over the last four decades the curricula in Sweden have aimed at creating a school for everybody though, without any significant success. Today, many students leave the comprehensive school without grades in the subjects Swedish, Maths, and English. Since the obligatory school was introduced, pupils that have been considered un-normal have been sorted out to other groups and classes, where teachers with special competence have been working.The designation ?a school for everybody? is described in perspective from four different definitions.

Dalsland som turistisk produkt : Föreställningar om turistifierade rum

Market capitalism sets the conditions for how the world is conceived, experienced and organized at various spatial scales (global to local). Currently, competitiveness, entrepreneurship and economic growth are key values that shape how the world is conceived, experienced and organized. Discourses of place marketing, place branding, and the construction of places as (economic) products, are part and parcel of the heightened commodification of space. Tourism has been a major factor in the commodification of place and space. More often than not, tourism has been seen as a possibility for peripheral places, in their struggle finding new ways towards development.
