Val av komplementmaterial för våtkompostering av klosettvatten
Emissions of insufficiently treated wastewater, mainly blackwater (i.e. wastewater from toilets), contributes to the eutrophication of lakes and seas. At the same time, blackwater is a fraction with a low content of heavy metals and, after sanitization, it can recirculate plant nutrients to arable land using the liquid composting treatment method. Liquid composting means that organic material is degraded under aerobic conditions. For sanitization, the blackwater needs to be treated together with energy-rich complementary material.
Svensk tjänstehundsavel : en återblick och nutidsbeskrivning samt förslag inför framtiden
In 1936 a governmental breeding project was started with aim on military use. The police later came to use dogs from this project as well. In order to utilize dogs that could fit for other purposes training and education of dogs for search of different substances and of guide dogs for blind persons was performed. A political decision to privatize the whole dog programme was taken in 1992.
During most part of the time one had serious economical issues since too few of the dogs that were bred could be considered to fulfil the basic demands for service. To satisfy the need of service dogs private bred dogs were bought as well.
Barns rätt och äktenskapsåldern : En kritisk studie av svensk rätt i samband med de grundläggande principerna i barnkonventionen
The Swedish rules for marrying in Sweden are different for swedish citizens and foreigners. A swedish citizen has to have permission from"Länsstyrelsen"to marry before the age of 18 but a foreigner may marry without permission at an age of 15, unless a higher age is required by the foreign law. The main question in this essay is if the swedish international law concerning the age of marriage is compatible with the Convention on the Rights of the Child and/or the Swedish Constitution. The comparison is based on mainly two questions: Primarily the Swedish international law is discussed concerning which marrying age is good for the child. Thereafter it is discussed whether it is discriminating to have different marrying ages for swedish and foreign citizens.
Han är som han är - En kvalitativ studie om upplevelsen av att växa upp med ett syskon som har autism
The aim of this study is to examine the experienced life situations of siblings growing up with a brother or a sister diagnosed with autism. The study is qualitative and therefore suitable to the purpose of studying the informants´ own experiences. Three women and one man, aged between 18-24 years, were interviewed through chatt programs on the Internet. The constituted perspective is phenomenological and the analysis were made by identifying meaning units in the text from the interviews. The theory used to interpret the result is systems theory and more specifically the structual family therapy by Salvador Minuchin.
Fältstudier och laborationer inom geografiundervisningen
The purpose of this study is to explore how teachers in Sweden and Croatia work with children that have problems like ADHD and dyslexia in school. I have chosen to compare pedagogical methods between Swedish and Croatian teachers which are used in work with children with difficulties when it comes to the education and teachers approach to these children. I have done a qualified study and have interviewed teachers in both Sweden and Croatia and one specialist in pedagogy in Croatia. I compared with these interviews information from earlier studies and literature. Results show that teachers in Sweden are of the opinion that every student who has these difficulties is different and therefore the use a variation of pedagogical strategies is crucial.
Environment simulation of track-based systems
Simulation means running a model of a system with suitable input and observing the corresponding output. Real-time environment simulation is a special kind of simulation used to simulate a control system's environment in real-time. This is done to test the control system before it is used in its real environment. In this project, computer simulation of a certain kind of environments, called track-based systems, is studied and a general model for track-based systems is developed. In this model, track layouts are represented by graphs, which is a flexible and extensible representation and a method for visualizing these layouts is presented.
"Hälsa skall vara kravlöst" : En webbenkät om studenters önskemål, intressen och behov gällande en hälsowebbsajt.
??The aim of this study was to define students? needs and wishes about the content of a health website. A questionnaire was distributed to 531 students at three different Universities studying two different education programs, of which 98 participated. The research was based on relevant articles, studies and literature. The study shows that students are interested in a health website and there seems to be a demand, among students, to improve their health.
INDUSTRIELLT EKOLOGISK STADSODLING : EN KVALITATIV STUDIE SOM UNDERLAG FÖR EN STADSODLINGSREVOLUTION I STOCKHOLM
Rooted in Industrial Ecology (IE) theory, this report evaluates how urban agricultural concepts and techniques, can contribute to improved ecological sustainability within the inner city boundaries of Stockholm. An overarching literary study as well as an interview was carried out, resulting in a qualitative analysis followed by suggestions for practical implementations. A substantial convergence was found between the eco-restructuring objectives of IE and the principal motives for urban agriculture. Consequently, eco-restructuring objectives are found in varying degrees in the presented urban agricultural techniques. Industrial symbioses, permaculture and combinations of urban agricultural techniques are tools which are capable of corresponding adequately to the diversity of urban settings.
Fukthaltsförändringar för skogsbränsle : En jämförelse av torkförloppet i grönrisskotade och brunrisskotade vältor
In 1994 a new Forestry Act was accepted in Sweden. One of the aims of the law is to raise consideration forpreservation of biodiversity. Since the new law got accepted and some time has passed, there now lie someinterest in examining whether the law has been effective towards its purpose. Methods suitable for analysishave been examined during this study. The content of this pilot study is based around five parameters whichcan be used to validate the effects of the new law.
Kontrollbox för häftare A6102
This report describes the construction and development of a control box, which is a tool for testing and verifying a certain model of Rapid?s built in staplers (model A6102). Basically the function of the control box is to interpret any errors that may occur in the stapler and to make it possible to test fire the stapler.The control box should be able to communicate with the stapler using a specialized communication protocol. The different data such as errors, firmware etc. from the stapler is presented in plain language on a display.
En jämförelse mellan amplifierad singelmolekylanalys och selektiv agar vid kontroll av hygienisering av avloppsslam
Bringing back the nutrients from the city to the country is becoming increasingly important, as the world?s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden
today. Sewage sludge may contain large amounts of pathogens, such as Campylobacter and Salmonella, why use can cause severe spreading of infections, both to animals and humans. These pathogens have the ability to survive for a long time in soil and water and therefore
some sort of treatment of the sludge is recommended before use.
Registrering av konstbilder: En översikt av forskning och praktik i en domänspecifik form av kunskapsorganisation
The purpose of this thesis is to present a review of research themes and practice in the field of art image registration. The objectives of the review are twofold. The primary task is to distinguish which problems, in regard to theory and practice, that have been dealt with in the field of art image registration and the secondary task is to investigate which discursive, institutional and tool-related factors have had an impact on theoretical discussions and practice in the art image domain. The empirical content in the review is structured according to four epistemological viewpoints and is analyzed with a domain analytical approach. The result of the study is that two major problems are frequently discussed in the art image domain, namely lack of standardization and which discourse is the best suited for registration of art images.
Utveckling av förpackningssystem för torra insatsvaror i livsmedel
This project includes development of new packaging for dry spices and an investigation of how to automate the production line. The preliminary investigations show needs of an environmental friendly packaging possible to re-close. After screening for suitable materials three concepts were developed, a stand-up pouch, a plastic jar and a metal can. The pouch was excluded in a concept choosing process. In this process it was also decided to further develop the metal can concept.
Utveckling av modellbaserad reglering i kommersiella styrsystem
In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.
Energieffektiva värmesystem : Lösningen till att nå energimålen i byggbranschen?
Sweden has an environmental goal to achieve until the year 2020. To achieve this goal the construction business has to take an initiative to use the modern techniques that are available to lower the energy consumption I buildings. There?s also a debate going on today regarding the energy demands set by the Swedish government through Boverket, some communities throughout Sweden thinks that the demands are to low and have therefore set up own demands regarding energy in buildings.The possibility to construct energy-saving buildings is today very great, with energy-efficient heating-systems and dense climate envelope. The interest to raise energy-efficient buildings have also increased as a consequence that the population have become more aware about their impact on the environment.
