Membranbioreaktorteknik- en framtida lösning på Lundåkraverket? : Membrane bioreactors- A future solution at Lundåkra wastewater treatment plant?

Membrane bioreactors (MBR) combined with biological phosphorous treatment (Bio-P) has been investigated if that could be an alternative to the future expansion with conventional active sludge treatment at Lundåkra wastewater treatment plant (WWTP) in the proximity of Landskrona, Sweden.The results showed that the surface demand in the biological treatment will be reduced with 67% with the MBR-alternative compared to a conventional activated sludge process. The nutrient removal in the MBR-solution was decreased or unchanged for nitrogen-, phosphorous- and organic parameters. However, the energy demand will increase with an estimated cost of approximately 1 million SEK annually. Moreover, the extra chemical consumption is estimated to cost 370 000 SEK annually.The disturbances caused by filamentous bacteria such as sludge dispersal could be resolved with MBR-technology because the membranes are not affected by these organisms. The Bio-P process combined with MBR-technology works if the wastewater recirculates from the membranes to an aerobic zone.In the proposal, there will be a new pre-treatment step, for instance hole screens.

Lärare om bedömning och betygssättning : Hur ser bedömningen och betygssättningen ut på olika skolor och hur likvärdig är den?

This essay examines how high school teachers in physical education and health thinks about assessment and grading. The essay show how teachers assess pupils during lessons and how teachers grade their students. The survey was based on interviews, in which six different teachers answered questions on the topic of assessment and grading. The issues surrounding assessment was linked to the theoretical concepts of formative and summative assessment, to see if the assessment methods teachers use. The issues surrounding grading was related to the theoretical concepts of validity and reliability in order to see how similar the grading is.The essay provides a picture of how the assessment and rate again looks different teachers.

Småbarnsavdelningar - bara barnpassning eller? : En kvalitativ studie om verksamheten på småbarnsavdelningar

In the curriculum for Swedish pre-school the focus is mainly on five concepts. These are care of the children, learning, influence, rearing and security. These concepts are to characterize the activities of the pre-school in Sweden.Back in time the focal point of pre-school activities for young children was mainly on security. The learning part became more prominent as the children grew older. When speaking to teachers and parents I do sense that some believe this is the case even nowadays.

Att rädda det förgångna : Om Walter Benjamins historiska materialism

The present essay concerns Walter Benjamin?s thought regarding history and temporality as he articulated it in his last work that was only published posthumously: ?U?ber den Begriff der Geschichte?. The purpose is to analyze Benjamin?s construction of historical materialism and to suggest a reading of it as directed towards an opening of history. For Walter Benjamin, every moment presents itself as a possibility of radical otherness: a possibility for things to be different.

detection and quantification of almond (Prunus dulcis) in food with ELISA

Reliable methods to analyze food for the presence of almond are important ? not only for those allergic to almond, but also for monitoring the compliance with labelling regulations (EG directive 2003/89). Until now the Swedish National Food Administration has used methods like rocket immunoelectrophoresis and real-time PCR to detect almond in food. These methods are, however, not sensitive enough for protecting the most sensitive individuals. Therefore, the performance of a commercial ELISA kit was tested with regard to specificity/cross reactivity and limit of detection for almond both in solution and in different matrixes.The limit of quantitation was at least 3,1 ppm (mg/kg) in solution and similar concentrations were measured in bisquits and chocolate.

Lågenergihus : Att bygga energisnålt

A large proportion of the energy consumption is in the building industry and a large part goes to heating our homes and premises. In the developing countries' development now threatens the large consumption of energy in our earth's climate. It is in the West world that we must be good role models in terms of energy efficiency. One solution to reduce energy consumption for heating of buildings may be to continue to build low energy houses and passive houses, but it is also about rebuilding the buildings that currently have high energy consumption such as the old Million program Houses. These buildings will be standing many years and their energy consumption will not diminish over time by itself and energy prices will certainly not diminish in the future.

Exil hederskultur-ett narrativ

Drawing on a broad theoretical framework that includes theories about globalisation and honourculture, this thesis aim is to demonstrate that globalisation and honourculture, constitute a conceptual network, i.e a structural relational matrix in which concepts are embedded. Being part of conceptual network, these concepts are related to each other ontologically. The idea of conceptual network, and the thesis as a whole, draw upon what has been called ?relational perspective?This study aims to show the impact of globalisation on honourculture. The study shows the importance of narrative in the construction of discursive boundaries.

Samhällets syn på fattigdom : En jämförelse av begreppen "nödtorftig vård" och "skälig levnadsnivå"

The purpose of this bachelor's thesis in social work has been to examine whether society's perception of poverty and poor people has changed over the more than 160 years have passed since the first national Poor regulation was enacted in Sweden. With a social constructionist approach and inspired by the critical discourse analysis we have conducted two studies to find answers to what differences and similarities between the concepts of scanty care (1847) and standards of living (2002). A study based on previous research was conducted to examine how society's perception of poverty has changed and designed in a historical perspective. We also conducted a textual analysis of relevant legal texts and legislative history to show how these texts reflect the society's official view of poverty based interventions targeted to poor people.The two sub-studies show that the concepts at different times in history has been crucial for the community support poor people were entitled to. Our overall conclusion is that despite today's advanced social policy there are many obvious similarities between the concepts of scanty care and standards of living.

Motivation ur ett elevperspektiv : En studie om vilka faktorer som har betydelse för elevers motivation

AbstractThis study deals with motivation as an overall concept, from a student perspective. It encompasses factors that could directly affect students and their positive or negative motivation, concepts such as relationships, communication, expectations and interactions and their importance to my informants.The study also discusses certain theories to show the different ways of defining motivation, specifically in relation to my informants and their and my conclusions. My ambition is to establish the importance of the concepts mentioned above, as well as perspective changes to the enhancement of the performance standards of a good teacher.The purpose of this work is to describe, understand and clarify the external and internal factors that affect motivation. In order to achieve this purpose, I chose to use a method of qualitative interviews with three students, with different backgrounds, schools and conditions but with a lack of motivation as a unifying characteristic. The research questions were as follows:What factors influence students' motivation?   What impact do achievement targets have in relation to the pupils? own motivation to learn?How important are teachers' expectations for the individual student's motivation?Within this study sub-concepts such as importance of expectations, relationships, and significant others are, according to my analysis, of great importance.

?Det är ju en naturlig del? : De anställdas känslor inför och arbete med uttryck för onani på gruppboenden för personer med utvecklingsstörning

The aim of this study was to investigate the emotions among the staff at the group housings when they observe the caretakers expressions of masturbation and how the staff handles these expressions in their daily and long-term work. The theoretical concepts that were used in this study are group housing as a public and private arena, occupational role, relation, humanistic effort, pedagogical effort, empowerment, care ethic and emotions. The concepts are related to each other and constitutes the foundation for the analysis of the empirical data used in this study. A qualitative study was carried out, in forms of half structured interviews with six informants, of which the majority was women. It came to light that the interviewees only had positive feelings for the caretaker?s expressions of masturbation.

Flavour improvement of water solutions comprising bitter amino acids

The aim of this project was to improve taste of a liquid food product, comprising extremelybitter and unpalatable amino acids and one unrevealed ingredient. The amino acids were Lleucine,L-isoleucine, L-valine, L-threonine and L-lysine monohydrochloride. Experimentaldesign was set up as a screening of water solutions comprising these ingredients (called BCAAsolutions) and added ingredients with potential to improve flavour. BCAA solution withingredients that were potential bitterness suppressors were evaluated in flavour, bitternessand/or palatability. Solutions of separate amino acids were also studied.
