Effektivisering vid produktion av järnvägsbro
Järnvägsbron vid Årstaberg kommer när den är klar att mäta 1,4 km, här passerar över 550 tåg per dygn. Bron är en del av projektet Citybanan och kommer att fungera som en spårväxel som styr fjärr-, regional- och godståg till den gamla östra Årstabron. Pendeltågen kommer då färdas på bron över Årstaviken och in i den nya järnvägstunneln vid Södra station.Entreprenaden gick från början till danska företaget Pihl och Son som efter en del problem gick i konkurs, underentreprenören Züblin fick då ta över projektet. Med en ny platsledning gjordes en hel del förändringar på arbetsgången och arbetsmomenten. Från 4 veckor per sektion, där en sektion mäter ca 30 meter lyckades Züblin tillslut effektivisera till 2 veckor.
Prosodisk förmåga hos svenska grundskolebarn med cochleaimplantat
Prosody can be characterized as the rhythm and the melody of speech. Prosodic features convey emotions, thoughts and geographic origins of each individual. Spoken language without prosody would be monotonous, without variations in loudness and rate. Children with cochlear implants perceive speech in a different way than children with normal hearing. Consequently the speech produced by a child with cochlear implants may sound different.The purpose of this study was to examine prosodic skills in Swedish children with cochlear implants and to compare them with the prosodic skills in Swedish children with normal hearing.
?Ett fantastiskt redskap!? En studie om hur personer i åldern 65 ? 75 år använder och upplever Internet i sin vardag
The main purpose of this master thesis is to investigate how six elderly individuals, 65-75 years old, use and perceive Internet in their everyday life. The focus in this study is to enlighten elderly people as Internet-users.In 2010 many elderly people are still digital excluded. In Europe and in Sweden efforts are made to educate citizens to use the Internet, and that benefits of the digital society should be available to all.This study is based on the following questions: what made the informants take an interest in the Internet in the first place? How and for what purpose do they use it? And how do the informants regard to their own Internet usage and its importance in society?We interviewed six people aged 65-75 years old, using semi-structured questions. The data was analyzed by using the theory developed by Hektor concerning Internet and information behaviour in everyday life.
Vilka förutsättningar finns för dyslektiker att arbeta integrerat med övriga elever? Which prerequisites exists for students with dyslexia for working integrated together with other students?
I detta examensarbete har vi undersökt vilka förutsättningar det finns för elever med dyslexi att arbeta integrerat i klassrummet tillsammans med övriga klasskamrater och hur pedagoger arbetar ute på skolorna med elever som har diagnosen dyslexi. För att få en djupare förståelse har vi tittat närmare på diagnosens betydelse, vilka hjälpmedel som finns att tillgå för att underlätta arbetet i klassrummet för dyslektiker samt om det finns någon förebyggande pedagogik mot specifika läs- och skrivsvårigheter.
Vi har genom kvalitativa intervjuer med pedagoger och specialpedagoger fått fram hur detta arbete kan se ut i dagens skola. Undersökningen genomfördes i två olika F-6 verksamheter belägna i Svedala kommun.
Slutsatsen vi har dragit efter vår undersökning är att det idag finns stora möjligheter för elever att arbeta integrerat i klassrummet under alla av arbetsdagens timmar. Men vi ställer oss ändå något tveksamma inför detta.
Hur tiggeri konstrueras som ett socialt problem i den massmediala debatten
The Swedish stock-market gives investors an opportunity to benefit from the global growth while financing companies invests and contributes to a socio-economic development. Parallel to the ownership of the funds also follows a responsibility as companies in the funds affect society and the environment. The growth of savings in funds, combined with an increased focus on sustainability has developed SRI (socially responsible investment). Therefore it is interesting to examine whether responsibility is an exception, which only concerns SRI-funds or a general principle, which includes the whole Swedish stock-market.The results of the survey makes it clear that all the Swedish major banks actively works to integrate sustainability within the respective bank's business to achieve a more sustainable financial system. Thus concludes the investigation that responsible investments are a general principle on the Swedish mutual stock-market.How responsibility is integrated in fund management differ between the banks.
På väg. En undersökning av en svensk stadsmotorväg

Olskroksmotetin the west and Jonsered junction in the east, a distance of about 11 km. The mainquestion was, can maintenance of areas and objects related to the motorway give greatermeaning to a system that currently lacks historical connection?The survey was partly an archival study and partly a physical examination of themotorway and its appearance today.The road through Säveedalen from Gothenburg has a long history that begins with theriver and its valley as transport routes.
E-handel och tillit : En kvalitativ studie om fo?retags och kunders perspektiv pa? tillit
Statistics indicate an increase in online shopping. This indication could result in the loss of safety factors for the customer, for example the possibility to physically examine the product, interact with professional store personnel and try the product before purchase ? factors which all could support the customer in her choice of company and product. The purpose of this study is to increase the theoretical knowledge regarding strategies in the area of trust-development between customers and companies. We have chosen to investigate what strategies web based companies apply and how they are perceived by their customers.
Förvärv och Företagskultur
Background: Acquisitions are a well-known method for increasing company size and strength on the market. But to reach the targets set, more than just a positive economic calculation is required. An atmosphere that supports the company's integration is needed, for which it is of great importance for management to understand the underlying sets of values that exist in the organisation, and to take into consideration the way they might become an obstacle or a tool for a successful integration. Purpose: The purpose of this thesis is to explain and understand how cultural change occurs and how it affects the employee, as a smaller company is bought and integrated into a larger organisation. Procedure: The analysis is based on theories on organisational culture and organisational change.
Prevalence of selected infectious diseases in Samoan dogs
SCA is the largest private owned forest owner in Sweden, with an ownership of 2 million hectares of productive forestland. To manage the planning of such large areas and to fit the traditional organization structure of a Swedish forest company, the planning approach is subdivided into three stages; strategic, tactical and operational.
The strategic part, based on a statistic sample of stands, returns a harvest level estimate which should then be implemented at actual sites in the tactical part. This procedure can lead to incompatible solutions as the strategic solution is not necessarily possible to translate into actual sites in the tactical plan. The geographic aspect is important in tactical planning due to the large costs for moving equipment and maintenance of a large number of forest roads.
Kraven på ägare till minireningsverk skiljer sig åt mellan olika kommuner
Discharge of inadequately treated waste water containing nutrients such as phosphorus and nitrogen as well as organic matter and bacteria is associated with a risk of eutrophication and contamination. The Swedish government has decided upon several Environmental Quality Objectives aiming to reduce the emissions of nutrients to water bodies.In Sweden, there are between 675 000 to 1 000 000 on-site sewage systems. Recent studies have shown that the function of small sewage treatment plants is in many cases insufficient. To prevent this regular service and supervision by a professional is needed. The focus of this study are small sewage treatment plants which use a technique where mechanical, chemical and/or biological reduction of pollutants is being used in the same facility to reduce nutrients in household wastewater.The aim of the study is to investigate how different municipalities ensure that small sewage treatment plants fulfill the requirements and reduce pollutants as efficient as the manufacturers claim.
Jämförelse mellan bullerreducerande beläggning och bullerskärm. : Ur ett kostnads- och tekniskt perspektiv.
Den bullerreducerande beläggnigen har en porös struktur som förbättrar dräneringen och reducerar buller vid källan men egenskaperna orsakar ett snabbt slitage och portäppning. Detta medför att beläggningen måste omläggas och rengöras oftare än en konventionell beläggning som t.ex. ABS 16. Kritiken mot den bullerreducerande beläggningen riktar sig på de höga drift- och underhållskostnaderna, detta gör att många väghållaren satsar på bullerskärm som bulleråtgärd. Syftet med arbetet är att jämföra bullerreducerande beläggning med bullerskärm, för att reda på vilken bulleråtgärd är mer kostnadseffektivt under 20 år. Ett teoriavsnitt kommer att förklara och beskriva på ett tekniskt sätt: väg, ljud och buller, bullerskärm och bullerreducerande beläggningar.Kostnadsjämförelsen mellan bulleråtgärderna omfattar investering, drift och underhåll.
Termoelektrisk lagring i system med fjärrvärmeproduktion
With increased deployment ofintermittent renewable energy, such aswind and solar power, energy storagebecomes necessary to help reduceproduction peaks. Thermoelectric EnergyStorage is a method still in researchphase, which stores electricity in hotwater at a temperature of 120 ° C. Thisthesis aims to examine whether theThermoelectric Energy Storage would bepossible to integrate into existingpower generation such as a combined heatand power plant, and how the technologypotentially could function in theelectricity market. ThermoelectricEnergy Storage consists of a chargingprocess and a discharging process, bothoperating by the working fluid CO2. Toincrease the efficiency of theThermoelectric Energy Storage, wasteheat from the district heating networkis integrated.A model of the Thermoelectric EnergyStorage has been developed and it wascalculated by thermodynamic propertiesof the working fluid, CO2, in thevarious process steps.
Framställningar av svenskhet i media : - En diskursanalys av tidningsartiklar om invandring och integration
The media plays a key role in constructing identities and categories, as its messages influence the way we understand the world. In the debate on integration issues, categories such as ?Swede? and ?immigrant? are often treated as obvious and unproblematic. ?Swedish?, being the norm, is seldom defined and frequently appears with subtlety. This paper set out to study what characterizes Swedishness in newspaper articles on integration issues, and how it is represented in relations to immigrants.
Uppvärmning med spannmål och trädbränslen :
This examination work brings up opportunities to invest in a construction for heating with grain
or pellets on farm level.
As example we have chosen Fröberga Gård which is a farm located in Östergötland outside of
Söderköping.
The farm`s residential buildings is to day heated with oil and electricity.
The result of our investigation shows that heating with grain is the best alternative, partly because
of economical issues but also because you can grow the grain on your own farm and by that you
can get better economy in your seed cultivation.
To grow 16 tonne of grain as is needed demand gives a insignificant increase of work.
Further an advantage is that no investment in machines is needed because all the machines witch
is needed already is in use on the farm.
In a situation where a new investment is needed as in the case we studied, is it often profitable to
invest in a integrated furnace. Because all the components are well adapted to each other, and
because that gives a high efficiency.
If you already own a well working furnace is it often most profitable to connect a burner to it.
It is important to know that heating with grain need more work than heating with pellets, because
the high contents of ash in grain.
Even if you choose pellets instead of grain the calculation shows good results.
Because peat is an excellent but fairly untested raw material for pelletsproduction we have
chosen to watch little more on its quality and conductions.
We discovered that peat has a high heating value which makes it possible to raise the heat value
in pellets through mix up peat and wood. Or you can make pellets with only peat and get a pellet
with high heating value. Even the calculation with peatheating shows good results..
Ett på allvar integrerat svenskämne? : En studie av uppgiftskulturen i läromedlet Känslan för ord.
The aim of this paper is to analyze and problematize the content in the teaching media Känslan för ord through an integrative perspective. This is done by using two sets of questions based on two of the didactic questions what and how. How is the content of the Swedish subject constructed in Känslan för ord? and How is this content integrated in Känslan för ord? The used material consists of a fairly large amount of literature which provides different approaches, priorities, and methods about the Swedish subject. This literature forms the base for the model used to analyze the course books.The results are based on an analysis of the exercise culture (uppgiftskultur) in the two books and are extensive.
