Långsiktigt spårväxelunderhåll - Förutsättningar och möjligheter

Due to their complexity and heavy wear from rail traffic, switches are a sensitive part of the railway infrastructure and moreover expensive to maintain. Furthermore, increasing railway traffic not only accelerates the wear rate but also obstructs the necessary maintenance measures. This paper examines the opportunities for a transition to a long-term maintenance strategy in the Swedish railway network. It contains a study of the maintenance strategy of Banverket, and also analyses statistics of errors in the railway infrastructure. The survey was completed utilising interviews with infrastructure managers, maintenance contractors, planners of railway operations and the Banverket material service department.

Beteendepåverkande designaspekter inom social media

This paper has it?s starting point in the midst of the debate concerning behaviour in socialmedia. Prior research has primarily been concerned with the role and responsibility of theuser while technology has been viewed as morally neutral. The base of the study isdiscourse analysis and a discursive psychology perspective is used to compare texts onTwitter and Facebook that were published during the events of the Boston bombings.The aim is to examine how platform users construct reality, groups and identities andwhat consequences those constructions bring. An interpretation of why the discourse ofTwitter and Facebook differ is grounded in aspects of design, which have been identifiedas having an influence on behaviour.

Konstruktion av efterbehandlare

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

UTANFÖRSKAP I ETT MAJORITETSSAMHÄLLE : En diskursanalytisk studie med fokus på romerna i svenska tidningar

In this paper I study how the minority group Roma appears in the Swedish media. I also look at possible similarities and differences in appearance before and after the disclosure of the Roma registration by the Swedish police in September 2013. To answer my purpose with the paper I treat the following questions:How is the minority group Roma constructed in the media before and after the disclosure?In which ways are the minority group Roma expressed in the media before and after the disclosure?I am using a discourse analytic method based on theories of construction between ?them? and ?we? and the media?s impact on social constructions and identities. By analysing twenty-eight articles from a period of one month before and one month after the disclosure the result shows that there are more similarities than differences between how the Roma are described in the Swedish media.

Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam : Chemical stabilization of mine waste with sewage sludge and calcium carbonate residues

Chemical stabilization of mine waste from Ljusnarsbergsfältet with sewage sludge and calcium carbonate residuesMine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide minerals. When sulphide minerals come into contact with dissolvedoxygen and precipitation, oxidation may occur resulting in acid mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as complexing agents for heavy metals and in this way increase their mobility.

Rättsenlighet och ansvarstagande i de ensamkommande flyktingbarnens asylprocess

Earlier this year the Swedish migration board gave a part of their responsibility for the separated children to those municipalities that have signed an agreement with them, so that the children can get the best handling of their matters and also to lift the heavy pressure of the Swedish migration board. Our aim in this paper is to see how this division is made and which areas of responsibility they have. We want to see how this process is being handled in relation to these children?s rights, the Convention on the Rights of the Child and the Swedish law. To get the best information possible we used a qualitative method.

Kappor inom damkonfektion - från grund till modell

Bakgrunden till rapporten var att det företag som medverkat i studien ville utveckla ett grundmönster för damkappor. Syftet med arbetet blev därför att utarbeta ett grundmönster med två ärmtyper som graderas mellan storlek 32-50, samt konstruera en kappmodell från samma grund. Utöver detta skulle även detaljkonstruktioner och specifikationer utformas. Frågeställningarna som styrde arbetet kretsade därför kring hur man på bästa sätt tar fram detta.All konstruktion utfördes i Lectra´s Modaris. För att ta fram grundmönstret jämfördes två arbetssätt för att sedan välja en av de grunder som konstruerats.

BUCO - avlastning och förvaring av småprylar i hallen

The goal has been to design a product for unloading and storing small gadgetsin the hallway. The aim has been to facilitate the search for importantsmall objects that people never seem to find when they need them the most.The aim has also been to provide a sense of relief when people enter theirhome, and they can empty their pockets on one spot in a very simple yet orderlymanner. The product would be able to sort out, and make the gadgetsaccessible, take as little space as possible, be easy to use and not be perceivedas heavy and clumsy. The work has been done with close involvement of afocus group consisting of 20 people of different ages and with different occupations.The behavior of the focus group has been observed and test modelshave played a crucial role in advancing the work troughout the project. Theresult is a series of storage products for the wall, of simple shapes which canbe combined together in different ways depending on hallway and the user?sindividual taste or preference..

Grundvattnets geokemi vid Gladhammars gruvfält, Västervik. Effekter av äldre tiders kobolt- och kopparbrytning

The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.

Barn som utsätts för våld i nära relationer : Vilken hjälp bistår socialtjänsten med?

The main purpose of this study is to find out what kind of help social service in one selected municipality in Sweden can provide for children who have witnessed or been victims of domestic violence. Using focus group interview this study investigate how the social workers meet the needs of these children. The bases for our analysis are the Organization Theory and the Attachment Theory, as well as previous research. Important results are that the social services are dependent on notifications in order to do their work and that the most common interventions are foster care, emergency foster care and/or family therapy. The difficulties that social workers perceive their work are unjustified families and heavy workloads.

Det medeltida Fårö - en studie av en ödegård utifrån ett genusperspektiv

The aim of this study was through applying a new perspective reach the people who during medieval time lived and worked on the farm. On the basis of my previously study and a gender perspective this study have compared general literature with local and then interpreted the farm from a local context. The questions raised here concerns division of work and spatial distribution on the farm as well as local impact on gender constructions.This study resulted in interesting problems within the archaeology itself but also in significant details about the farm. No gender restrictions could be seen in the houses except in Hus 1 were a smaller space, which probably used as storage or a workshop had been restricted tomales. Instead the buildings social space mainly consisted of a mixed gender environment.

EN MILJ?STUDIE OM DE GEOKEMISKA F?RH?LLANDENA I SK?RHAMN, SVENSKA V?STKUSTEN

The following study aims to investigate the environmental conditions of the harbor of Sk?rhamn, a small fishing community on the west coast of Sweden. The interest to do so rose as a newly built apartment residence failed to connect the sewage pipes of 18 apartments, causing the untreated sewage running into the sea. The parameters accounted for are the C/N ratio, total organic carbon (TOC) as well as total nitrogen present (TN) and ?13C in the top ten centimeters of a sediment core retrieved in the Sk?rhamn harbour.

Slam ? en outnyttjad resurs i skogsbruket

Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.
