The primary focus of this Master thesis is to study how industrial house building can be implemented during production of rental flats under the terms of public procurement. In order to determine a suitable working process as well as presenting a possible architectonic result of the process, a case study is carried through.A housing projekt is designed on a site i Malmö, where the commisioner is MKB Fastighets AB and the contractor is NCC Komponent with the industrial building system NCC Komplett. The focus of the design is to accomplish high quality apartments to a resonable price, as well as solving the overall scheme for the site.The housing projekt, Kv. Flaggskepparen, built on the consept of a single house model, used to handle the entire site, shows that the building system is well suited to accomodate the commisioners demands.In order to reach the best possible architectonic result with the building system, cooperation initiatded in an early stage of the process is neccesary.A model is proposed to handle the situation under the terms of public procurement. The model suggest that the geometrical design is mainly carried out after inquiry and that architectonic qualities should mainly be defined in a non geometrial way for inquiry..

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

Construction production always contains different disciplines whose priorities andinterests can be very diverse. Good communication and coordination are essential tominimize misunderstandings and achieve good quality in the end result. This makesplanning a central part of the production management. In a world where conditionscan change as often as daily, being well prepared increases the opportunities to stayflexible and decrease negative effects of the changes.This study has been done in association with Skanska Foundations district North inStockholm in order to investigate how visual planning can be used in the productionmanagement to optimize the coordination and the quality.The history of Lean started at Toyota, but the concept are now spread over theworld and are used wide outside of the car industry nowadays. What?s challengingabout Lean in foundation projects is to embrace a long-term perspective and invest insolutions that are profitable in the longer term, instead of solve problems by onlytreating the symptoms.A holistic perspective is crucial in order to truly understand Lean.

The Annexin-V/propidium iodide (AV/PI) assay detects early membrane changes in spermatozoa and viability using flow cytometry. It is an objective method that evaluates a much larger number of single spermatozoa compared with the usual estimation of motility, the most commonly used method for routine sperm evaluation. In the present study four ejaculates from four stallions were used in a split-sample design to investigate whether and how the number of intact spermatozoa is affected over time and after incubation at different temperatures, either those recorded during shipment of stallion semen for AI (9 or 5°C) or room temperature (20°C). The Annexin-V results did not reflect the motility results that were monitored in parallel. While motility decreased over time, the number of spermatozoa with intact membranes (viable) remained unchanged for at least 21 hours following a short period of initial instability.

With examples from a single classroom situation, several educational moments show what goes on between the teacher and the student. The teacher?s responsibility in the learning process is, with a gesture frozen in the air of the moment, to lead and follow the student in her tentative efforts at seeking knowledge. Initially, it is an attempt to shed light upon the "not yet seen" with a certainty that the student herself possesses the capacity and the aptitude to reach greater insight and clarity in her understanding. The Validation/Feil Method presented in this instructional situation illustrates how best to communicate with elderly people suffering from Alzheimer?s dementia.

The present project was initiated with the aim to create pattern modules for use in public environments. My intention was to let the properties, of the specific materials used, have a marked influence on the realisation of the final form. I also wanted to find a material, which is suitable from the perspective of sustainabilityand possibilities to create modules from it. The work was initiated with a study of some candidate materials and many sketches before I finally made my choice. My decision was clear after a visit to the company Glasfabriken inKalmar.

Companies must constantly adapt to new concepts emerging in society. Socialresponsibility and sustainable development are modern concepts of today and offer avariety of activities to choose from. Therefore companies ask themselves: what areour goals and how do we reach them?The purpose of this study is to examine the possibility of creating a simplifiedmodel,targeted towards management for prioritization and decisions on variousinvestmentspromoting the environment. The research focuses on companies from themanufacturing industries.

Yesterdays common fertilizing strategy was to apply phosphor (P) and potassium (K) in thefall a few times in the crop rotation. In the spring only nitrogen (N) was applied. Recent trialsand studies has shown that this strategy, N+P/PK, is ineffective compared with the systemwhere NPK is spread every year in the spring. The strategy with annual NPK-fertilizer in thespring has proven to be better for the crop, the environment and the farmers economy.In the NPK-system the crop responds with higher yields and better quality, especially in thespring cereals. This is mainly because of an interaction between the different nutrients in thefertilizer.

The first part of this essay is about a single-family house that we have planned and projected. Thesecond part is a deeper study in ways to further insulate windows when they are not in use.In the first part the building?s design and its most important construction elements are described.The planning of all major installations (heating, domestic water, ventilation, sanitation, electricity)are reported so that one can in principle start construction of the house. In addition there arecalculations done on the building?s energy management.The result is a two stored house angled toward the south.

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

 The Swedish school of today reflect the society we live in. We live in a multi cultural society and in our schools there are pupils with different backgrounds, cultures and mother tongue, which make it necessary for every teacher to treat every single pupil?s need and condition. The education in Sweden must be equivalent, according to Skollagen, 1 kap. 2§.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

In today?s school in Sweden the assignment of community encompasses mediated values and education of democracy as well of single subject matters. What does it mean then, that teachers have a certain kind of idea of democracy, and what implications may biology have for the assignment of community? In upper secondary school there are quite many courses in biology with a national curriculum, and findings show that students of teaching perceive or think of biology as helping to promote the dual-purpose of teaching. In this study, the author of the paper has interviewed four future teachers of upper secondary school with biology as one of their main subjects.

This Master?s thesis is a comparative study of information retrieval results between three distinct search strategies in simulated automatic query expansion in a bibliographic database. Our purpose is to investigate which of the search strategies score the most effective precision and to what extent the same relevant documents are retrieved (overlapped). A thesaurus attached to the database is used to select appropriate descriptors for the baseline query formulations which subsequently are expanded with hierarchical relations. The search strategies are s1: A baseline query with two or three descriptors, s2: The baseline descriptors combined with at least one Narrower Term, s3: The baseline descriptors combined with Narrower Term and at least one Broader Term.

Cross-suckling, i.e. when an offspring nurses a female other than their own mother, occurs in pig production systems where sows are group housed during lactation. As production systems where several sows and their litters are housed together during lactation are getting more common, the need of knowledge regarding cross-suckling increases. The overall aims with this thesis was to investigate how sow behaviour and productivity are associated with the occurrence of cross-suckling, and to investigate consistency in sow nursing behaviour related to cross-suckling. The study included information about the first 4 parities of 40 LxY sows kept in outdoor and indoor production environments. Sows were single housed the first 2 weeks after farrowing and group housed (4 or 5 sows per group) from 2 weeks after farrowing until weaning, 7 weeks after farrowing.
