Solenergi på Kvarnholmen
In recent years it has become more and more evident that man has contributed to much of the climate changes that have taken place during the last century. A major challenge today is to reduce emissions and energy usage at the same time as the global population is growing. To contribute to a better environment, Stockholms Stad has set at target of becoming fossil fuel free by the year of 2050. The construction of new districts is done with this goal in mind; energy efficiency and renewable energy sources are examples of methods to achieve this.Solar energy is considered to be a sustainable energy source and the most common techniques to harvest solar energy in Sweden are solar cells and solar collectors which produce electricity and heat respectively. This report aims to investigate whether an investment in any of these systems would prove to be economically beneficial at Kvarnholmen, a district under construction in eastern Nacka, Stockholm.Since the finished blueprints only cover a small portion of Kvarnholmen, the report examines the possibilities for a house where construction has already begun, Nya Kvarnen.
Måltidsmönster, kost - och - medievanor bland överviktiga 15-åriga flickor och pojkar
Objective: The aim of this study was to compare equations used to calculate BMR to values of BMR obtained from measurements in order to determine the most suitable equation to be used on children and adolescents with CF.Design: The participants where children and adolescents with CF. Data was collected from the division of Clinical Nutrition at Uppsala Akademiska Sjukhus. Age, weight, height, BMI, BMR, FFM and FM was recorded from 27 measurements. BMR from the participants collected from the indirect respiratory calorimetry was compared to the results obtained from five equations used to obtain a calculated value of BMR.Results: Tverskayas equation was best correlated with the measured BMR for the whole group. The equation underestimated BMR for the participants with a measured BMR over 1400 kcal/24h and overestimated BMR for participants with a measured BMR under 1400 kcal/24h.
"Det finns möjligheter med allt och i klassrummet finner man svaren." : En studie av lärares arbete i ett mångkulturellt klassrum
Our intention with this study is to investigate teachers work in a multicultural classroom. For the purpose of this study, a web survey was constructed. The investigation was carried out among teachers on three different multicultural secondary schools in Sweden. 53 teachers informed us about their own experiences and thoughts concerning their work in a multicultural classroom. Conceptions as multiculturalism, methods in teaching, the climate in classrooms, teacher cultures and interculturalism has been used in the study.
En undersökning av Libra IIIs OPAC utifrån två perspektiv
This master thesis is an attempt to study the interface in itself, where the human meets the machine and the problems that can arise. I study a particular interface, namely the OPAC of Libra III. In 1999 IFLA presented recommendations for what an OPAC shall contain, and in one part of my master thesis I compare Libra III with these recommendations from my opinion. In another part of my master thesis I make an investigation where I let five by me chosen persons answer some questions from me, both by doing and verbally. I draw the conclusion that Libra III follows most of the recommendations of IFLA in a sufficient way.
Total organic carbon (TOC) and chemical oxygen demand (COD) - Monitoring of organic pollutants in wastewater
Total organic carbon (TOC) and chemical oxygen demand (COD) are two methods used for measuring organic pollutants in wastewater. Both methods are widely used but the COD method results in production of hazardous wastes, including mercury.The purpose of this study was to validate the method TOC that will replace COD and find a factor to convert TOC to COD. In this study 26 samples were analyzed from four sewage treatment plant in the municipality of Enköping.The results show that the COD method could be replaced by the TOC method.The factor for COD/TOC was between 3.1 - 3.3. Both methods will be used in parallel until 2013 when it will be forbidden to use the COD analysis..
Hur kommer barn till tals i domen?
The purpose of this essay was to see how the child's voice was being heard in the verdicts in trials. I looked into court cases where parents wanted custody of their child/children. The focus of my analysis was on how the verdicts were presented and if the child/children were described in the court cases. The method that I used was qualitative documentanalysis. I chose seven court cases to investigate and analyse.I described theories of Foucault's power to get a different perspective on courtroom cases and the children's voice.
Dialogicitet inom sfi : Hur upplevs talövningar av vuxenstuderande inom sfi?
Our governing documents give teachers guidelines as to how to carry out their task in the classroom. To guide a learner requires knowledge, not only about the policy of our governing documents but also skills to see the connection between the teacher's task and its practical implementation. By studying learners' experiences of teaching contexts, I have been able to evaluate how the teaching methods live up to the intentions of the national governing documents in Sweden.My study is based partly on a survey that I completed and partly on the theory of Dialogicity. Here I saw clear connections between my informants' experiences of verbal exercises in the teaching and the theoretical background I have chosen for my study, Dialogicity. I have presented and analyzed the verbal exercises in four differentiated contexts.
Små skogliga vattendrag i Värmland - Generell beskrivning, förekomst av traktorspår samt spårens inverkan på bottenfaunan :
Modern forestry requires a high degree of machine traffic for clear felling and scarification operations. The machines most frequently used are big and the traffic often results in tracks on the forest ground. There are many small streams running through a forest, in connection to logging operations, machines might cross these frequently. These crossings could result in the erosion of fine particulate inorganic matter, which ends up in the stream. The aim of this thesis was to give a general description of small forest streams of order-one in the county of Värmland and to determine the frequency of machine tracks in small streams.
Lärares syn på arbetet med partikelbegrepp i no-undervisningen
In this study we have interviewed eight teachers about when and how particle concepts should be taught. All of the surveyed teachers argue for an early introduction. This view is also consistent with the scientists on when the particle concepts should be introduced. By an early introduction teachers and scientists consider the age between 6-12 years old. A majority of the scientists and the surveyed teachers use concept of change as a entery point to talk about particle ideas.
?Film ?r ju ett s?tt att kommunicera med m?nniskor.? En studie av Naomi Kawases portr?ttering av att vara kvinna i relation till en gemenskap.
By analysing Still the water (2014), Radiance (2017) and True Mothers (2020) by Naomi Kawase this essay will look at her work to see how she portrays the experience of being a woman in relation to her community. Looking into her way of using the camera by applying the theory of haptic visuality allows the spectator to identify themselves in a bodily relationship with the image. By using the camera to closely frame objects of importance for the characters, Kawase leads the spectator to understand the world of the film and enables a more profound understanding of their experience. For the community to be of importance for the women it must be founded in the feeling of security and a confirmation of their feelings. Once secure, the women can express themselves and by that, feminist politics..
Utvärdering av öppna dikens status och funktion : en förstudie i Västmanlands län
Evaluations of open Ditch status and function, with an assessment of suitability of a conversion to a two stage ditch as a low maintenance alternative.
To illustrate Swedish drainage problems this work focused on two agricultural drainage associations assessed in detail with a new method called MADRAS (Minnesota Agricultural Ditch Reach Assessment for Stability). With the assessment of the MADRAS method estimates were made to conclude the ditches operating
problems.
This was made through measurements of sediment depths, mass bank failures etc. in order to quantify ditch problems and propose practical actions for improved ditch stability and water quality.
The MADRAS surveys were conducted in two main ditches that drains 2900 hectares of land on the northern shores of Mälaren. In the study measurements of the ditch cross-sections were also conducted to compare actual profiles with the original map profiles.
The evaluation showed that parts of the studied ditch sections were operatively poor; main reason was mass bank failure, undercut channel banks, sediment aggregations
and narrowed ditches. The profile survey shows that a majority of the profiles 80 % has sediment accumulations there remains only 64 % of the original profile from the map.
Personlig integritet och kreditupplysning
Most people would agree that privacy is a civil right, and that we should not be deprived of this civil right for other than legitimate reasons. The difficulty lies instead in how to decide where the legislative boundary should be drawn for the right to privacy, in order to protect the individual from an undue intrusion of his privacy. There are a number of areas where the right to privacy comes in conflict with opposite interests. One of these areas is credit report. In this master thesis the author discusses questions as, what is the meaning of the word privacy, and whether the protection of privacy is sufficient in the legislation concerning credit report? Also a comparative study of the Swedish and the English regulation is performed.
Förskolebarns motoriska utveckling : -Hur en förskolegård bör utformas för bästa tänkbara utveckling av barns motorik
The purpose of this study was to interview different groups of people (preschool teatcher, parents and theire childen) involved in preschool about their view on outdoor activity and children´s motoric development, and how a preschool yard should be designed to promote childrens development.All parties regard outdoor activity as very important for the development of children. They also think that the outdoor environment today is good but that it could be improved by including some trees and hills. The yard should also contain soil, sand, clay and water. The children prefer grass on the ground over other substrates. This study also gives good indications to decision makers how to build new or to reconstruct pre-school yards in the future..
Att vara i kroppen och befinna sig i nuet : en studie om mindfulnessbaserad stresshantering på vårdcentral
This is an examinaton of welfare officers and patients experiences of a course in mindfulnessbased stressreduction in primary care. The authors used a qualitative method and a phenomenological hermeneutics scientific philosophical position. The analys of the data appeared by using three theoretical perspectives; cognitive, coping and Antonovskys Sence of Coherence. The purpose was to get a deeper understanding of what mindfulness is, how a course in mindfulnessbased stressreduction can be arranged and how it is comprehended by the welfare officers and previous participators of the course. To get an opinion of the issue the authors wanted to know the welfare officers intention of the course, to which patients they provide the course, what the participators thought about their situation before and after the attendence and if they had assimilated the knowledge and if so how it was applicable.
