Rostfria stålkonstruktioner och rostskyddsbehandling av stålkonstruktioner enligt Eurocode

Steel is an excellent material to build with, but consideration must be given to the fact that unprotected steel corrodes, rusts, therefore, as a rule, the steel must be protected in some way. This can be done by reducing the tendency of the steel to corrode by using stainless steel or by treating the steel with a protection method. The two most common methods of protection are corrosion protection paint and zinc coating. To determine the method, the corrosive category must first be evaluated and this is done in accordance to EN ISO 12944-2:1998.Stainless steel is available in many varieties but only some of them have properties that make them suitable for use as construction steels. There are many factors to be considered in the design of stainless steel to prevent corrosion from occurring.

Hur min dyslexi påverkar mitt författarskap

The aim of this essay is to examine three separate Swedish public libraries and their respective websites on the grounds of the usability sciences. I firstly had to summarize the main properties of the usability-field in order to gain an extended knowledge of its purposes and possible usage for today?s library systems. I was then able to apply the extended knowledge in the examination of the three library websites and the purpose of determining whether or not they were designed according to the standards set by the usability-sciences.Usability is a rather new science that deals with the dissection and examination of computer-based systems, in order to find the key components that make systems user-friendlier. With user needs being the main focus of its research, usability tries to meet all the different needs of the modern user and construct systems that are less system-centered and more user-centered.

Konstruktion och utprövning av datorbaserat test för intonation och rytm : Icke-språklig Testning Av Prosodi - ITAP

Generally prosody is described as the rhythmic, dynamic and melodic features of language. Prosody is further often described as suprasegmental, since its properties go beyond vowels and consonants, which are segmental characteristics of language. A relationship between prosody and music has been noticed and described for several decades. At present, there are several studies proving relationship between prosodic and musical abilities. The aim of the present study was to construct a test for prosodic non-linguistic perception and production regarding intonation and rhythm. The test was tried out on 16 children with typical language development aged 4;6-7;6 years. Before testing of ITAP each participant were asked about musical experience.

Privata skogsägares benägenhet till röjning i Gudrunområdet : En kvalitativ intervjustudie

The purpose of this study was to examine how small-scale private forest ownersmake decisions regarding pre-commercial thinning. In 2015 it is ten years agosince the storm Gudrun hit the southern parts of Sweden and now large areas arein need of pre-commercial thinning. This study is built upon qualitativeinterviews with seven small-scale private forest owners with forest properties inthe county Kronoberg. The respondents were chosen by the modelSKOGSÄGARPROFILENTM (forest owner profile).The results of the interviews showed that five categories: ownership, the stormGudrun´s impact, silviculture, forestry contacts and driving force was important.How will their purpose and aim affect the pre-commercial thinning? Personalinterests, and expectations of the next generation to take over, are purposes thisstudy has found.

Utvärdering av försvarsspecifika radiovågformer

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

Genetisk variation av betydelse för adenosinsignalering vid nydebuterad reumatoid artrit

Rheumatoid arthritis is an autoimmune disease, where joints are attacked by the own immune system, leading to chronic inflammation and destruction of bone and cartilage. Inflammation is a complex process, controlled by many different substances. One of them is adenosine, which has anti-inflammatory properties. In this project, three polymorphisms in different genes, involved in synthesis and signaling of adenosine, were genotyped for 188 patients with RA and 362 controls without RA. The results shows that for the polymorphism in A2a, a gene coding for an adenosine receptor, there was no significant difference in genotype distribution between the groups.

Utredning av fastighetsel i ett äldre och ett ombyggt flerbostadshus i Gävle

The residential and service sector in Sweden accounts for approximately 38% of the total energy usage and Sweden has an aim to reduce the total energy use by 20% by 2020 compared to 2008, which means residential sector will have to improve energy efficiency. As part of that a law was instituted by the Swedish parliament that all properties must have an Energy Performance Certificate (EPC) to thereby give the property owners a greater insight into energy use in their buildings and propose recommendations for energy-efficiency measures. On the EPC, a value on the building's energy performance in terms of energy use in kWh / m2 per year is declared, of which electricity is a share of it. Instructions on what to include in the amount facility electricity for running the facilities is regulated by the authority for building, Boverket while SVEBY has made an interpretation of the regulations in their report "Brukarindata bostäder" where they have a table on what should be included in the amount and what not to include.This report is a study of two similar apartment buildings, where one of the buildings recently underwent renovation, to see if the declared amount of energy for electricity, in the EPC, is consistent with the measured value, and whether there has been any reduction in facility electricity in the renovated building after the renovation.The result shows that the measured value of the building electricity was 2.6 kWh / m2 per year, 28,8 %, lower than the declared value in the building that have not undergone a renovation. Calculation of values from previous years (2011) by the same percentage of facility electricity as in the results of the measurements, 56.7%, it becomes clear that the declared value for facility electricity in the EPC of the renovated building do not correspond with reality and that there has been an increase in use of facility electricity after the renovation..

Förvärv och försäljning av fastighet med förorenad mark : Särskilt gällande ansvar och friskrivningsklausuler

Properties are bought and sold daily, which means that it is of great importance with rules that regulate the acquisition. The rules on who should be held liable for a property brought to a head when the acquisition relates to a property that is loaded with contaminated soil. The purpose with this thesis is to investigate who could be held liable for contaminated land and also whether an exclusion clause can affect the separation of responsibilities. Two different liabilities can occur depending on which law that should be applicable, MB or JB.MB's rules apply to anyone who may be subject to decontamination responsibilities, which is regulated in Chapter 10. MB.

Kvinnligt Ledarskap eller ledarskap på kvinnors villkor En fallstudie av föreställningar om ledarskap och genus i Womentor

The purpose of this study is to investigate the perceptions of leadership and gender issues circulat- ing in Womentor leadership development programme, and to have a discussion around what conse- quences they may have on participants' careers. To answer the question I have used a qualitative approach in the form of 10 interviews and non-participant observations. The theories in this study are based on gender and leadership issues.The problem which forms the basis of this study is the underrepresentation of women at senior posi- tions. A basic assumption in this study is that notions of gender and leadership affect the individual's ability to act. The circulating concepts identified in Womentor are: The leader who wants to be a manager, The leader who gets things done, The communicative leader, Change leader, The motiva- tional leader and The leader as a role model.

Energieffektivisering av ventilationssystemet i konsthallen Sandgrund Lars Lerin

Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.

The study discusses different factors that affect the private forest owners consideration of nature conservation and give an insight in different generations attitude to nature conservation. Other topics that are discussed is if future change of generation will change the consideration of nature conservation in Swedish forestry and what is needed to enhance the interest in nature conservation among forest owners.This study is the result of interviews with a number of forest owners in the county of Uppsala, Sweden.

Frekvensreglering i det nordiska kraftsystemet

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

Genernas påverkan på köttkvaliteten

Multiple factors are involved in control of beef sensory quality so great variation can be induced. The perception of meat quality can be affected anywhere in the product chain. Both the environment and the set of genes of the animals have an effect on the final output. A problem facing the beef industry today is the significant variations in meat quality between individual animals, which is reflected in the uneven quality of the meat that reaches the consumer. If the quality of meat in stores varies significantly over time, the consumers? trust may decrease.
