Within all industries, there is a change in working time required; this also includes the construction sector. However, the way construction sectors are differentiated is by not having been given the opportunity to be practiced or tested.  The aim of this thesis that we have done in collaboration with the Concrete Industry was to investigate the possibility of developing an automated method for quality assurance of SKB at the site. The idea is to make the O-funnel to be more utilized and therefore ensuring that the appropriate concrete quality is provided which eventually would lead to a better development in the production process.The project has involved theoretical work and laboratory experiments. The theoretical work gave us a good foundation at the beginning of the project. After gathering the information and material, the laboratory experiments began by SCC in their laboratory in Hammarby. The collected data from the various laboratory tests formed the foundation for trying to relate measurements for consistency of SCC with each other and therefore find out how measurements from O-funnel varies with different concrete mixtures.

Bakgrund Forskning har visat att hur länge barn ammats, har betydelse för deras hälsa senare i livet. Även barnens sociala miljö har visat sig ha effekt på hälsan och barnens matvanor. Salut är en satsning av Västerbottens läns landsting med målet att förbättra länsbornas hälsa fram till 2030.Syfte Syftet med studien var att undersöka treåringars matvanor, Body Mass Index (BMI) och fysiska aktivitet i relation till amningsduration och familjekonstellation.Metod Studien genomfördes genom ett samarbete med Salut som utformade och delade ut en enkät via barnavårdscentraler till samtliga föräldrar vid treårskontrollen. Enkäten innehöll frågor om barnens fysiska och psykiska hälsa, samt livsstil och levnadsvanor och totalt beabetades 210 av enkäterna i denna studie, där 16 frågor valdes ut. Dessa analyserades sedan statistiskt i IBM SPSS 21.0 Statistics.

The river Göta Älv reaches between Vänern and Gothenburg and is the main raw water source for Gothenburg that supplies about 700 000 people with water. To protect and maintain a high water quality, continuously samples and water analyses are made throughout the river. In 1998 a protection area was founded between surte and Lärjeholm where the raw water intake is. This was made to increase the awareness of the importance to protect the water. However, there is a lot of contribution of untreated stormwater to Göta Älv within the protection area.Göteborg Water and Sewage Works commissioned this thesis where two areas, Tagene industrial area and Kärra residential area, with untreated stormwater outlets within the protection area are studied.

SyfteSyftet med denna studie var att undersöka sensitiviteten och specificiteten hos BMI vid klassificering av övervikt, samt att jämföra gränsvärdena för övervikt mätt med BMI med gränsvärdena för övervikt mätt i fettprocent med BodPod.MetodUrvalet i studien bestod av 359 deltagare mellan 30-50 år (medelvärde ? 39,7 år). Av dessa 359 var 192 kvinnor och 167 män. Deltagarna var indelade i fyra aktivitetsnivåer ? stillasittande, lågaktiva, aktiva och mycket aktiva.

Vetenskapen har på senare år försökt fastställa de olika orsaker som leder till fetma. Det är känt att högt energiintag och för lite motion för eller senare hos de flesta individer resulterar i fetma. Det som kan konstateras är att ärftlighet i samspel med miljön vi lever i och påverkas av kan vara den huvudsakliga orsaken till en rad sjukdomar inklusive fetma. På senare år har forskare upptäckt olika gener som på ett eller annan sett är involverade i ämnesomsättningen. En sådan gen är ?fat mass and obesity associated gene?, FTO.

A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.

The purpose of this investigation was to find out more about students? spontaneous ideas about properties and transformations of matter. Examples of matter chosen are such which students know about from everyday life and focus is mainly on the questions if students know that all matter has weight and that matter is preserved in transformations.The method used is semi structured qualitative interviews with individual students. Different experiments were carried out together with the students who afterwards were interviewed. However, the students show varying answers and no generalizations can be done.

WPF is a newly introduced graphical system that is a part of Microsoft?s .NET Framework. This report will evaluate WPF and its features. A comparison is made mainly towards the previous version of .NET which is .NET 2.0. The work is partly theoretical and partly implementational.

It is estimated that 22 000 contaminated areas exist in Sweden today. In order to classify the risk of contaminant migration from these areas and to prioritize which of these contaminated areas should first be treated, the Swedish Environmental Protection Agency (EPA) has designed a method, for the investigation of contaminated areas (MIFO). One of these contaminated areas is the landfill Gräsötippen outside Köping. The landfill has been used by both Yara AB and the Köping municipality between the years 1945 and 1975, and both industrial and household waste have been deposited there. The aim of this report is to survey which contaminants that can be found in the soil and water in the landfill Gräsötippen and to evaluate the migration of these contaminants.

Political scandals are constantly abound in the media, rulers face the global tribunal of the mass media and are forced to defend their actions and above all, their position in society. This essay concerns itself with that defence ? more specifi- cally with the defence of four Swedish politicians in high office during four different scandals. Gudrun Schymans? eva- sion, Laila Freivalds? dealing with the tsunami disaster in Thailand, Annie Lo?o?fs? tangle concerning representation notes and public documents and Tobias Billstro?ms? statements concerning undocumented immigrants and asylum seekers.

Chemical substances are spread diffusely and uncontrollably as a result of the increased consumption of goods. REVAQ is a certification system that works to reduce the flow of hazardous substances to Swedish treatment plants and to create a sustainable nutrient recycling. According to REVAQ, the yearly accumulating rate of metals should not exceed 0.2% in soil per year. Silver and bismuth are two metals that do not fulfill this requirement. The silver concentration in sludge decreased during the last decade, however the last few years, it has leveled off.

The technological legacy from the early electrification of the Swedish railroads has resulted in a power grid with a lower grid frequency than the national power grid from which it is fed. Energy transfer between these power grids with different frequencies requires substations, adapting the grid frequency for the rail road power grid. For this purpose, a feeding power grid has been built, stretching across the country from Boden in the north to Tälle/Häggvik in the south.Power transfer in the Swedish power grid results in voltage angle differences which increase with increasing loads and transfer distance. These voltage angle differences are transferred from the power feeding substations to the rail road power grid, will in some extent cause loss of energy due to unwanted power flows from north to south.To minimize the losses due to this phenomenon, a power management system called EFS 132 kV has been developed and implemented. The system minimizes the unwanted power flows and controls the desired power flow for a good distribution of loads between the power feeding substations.This thesis investigates the extent of the transmission losses avoided due to the EFS 132 kV that coordinates the idling angles to a common reference point.The results indicate that EFS 132 kV affects the power flow, especially between the northern substations through an improved load distribution.

This report is the result of a master thesis at Linköping University - Institute of Technology and Uppsala University at the request of the chassi workshop at Scania CV AB in Södertälje. Since the beginning of the 90's, Scania CV AB has had a close cooperation with Toyota from which, among other things, the Scania Production System (SPS) has evolved. SPS explains Scanias' values, principles and priorities. The Technician department (MST) at Scania Chassi in Södertälje believes that SPS can streamline the technicians work and help them become a more homogeneous group. The purpose of this master thesis is to initiate an implementation of SPS within MST through two pilot projects involving both the product and process technicians. The SPS principle Normal Situation - Standardised working method was required to be implemented within one work task each for the two groups of technicians with special attention on the three subprinciples Standardisation, Takt and Balanced flow. The master thesis fulfilled its purpose as the two pilot projects initiated the implementation of SPS within MST and the three sub-principles Standardisation, Takt and Balanced flow were implemented within the two chosen work tasks.

Milk allergens were digested by allowing them to flow through a chromatography column, where pepsin was conjugated to the stationary phase of the column. The allergen fragments were then characterized both biochemically, by using SDS-PAGE and gel permeation chromatography, and immunologically, by examining their reactivity to IgE and monoclonal antibodies..

The purpose of the study is to investigate the possible effects of an unstable ventilation system and its influence on energy use and thermal comfort. The report also explores how qualified personal working with HVAC view and handles system control.In order to meet the requirements in energy efficiency and a comfortable indoor climate control regulation is a prerequisite. With optimized increased complexity of the climate systems, it becomes more challenging to control the system and the risk of unstable control increases. No previous studies about what affect an unstable system can have on energy use and thermal comfort have been found.The report is based on several tests were the controlling variable has been increased until the system becomes unstable. Two different types of unstable systems have been investigated.
