Lyftanordning för kraftuttag

This thesis has been developed inassociation with Strängbetong AB, Sweden.A few years backCementa AB introduced a new type of cement on the Swedish market: Byggcement,which is a Portland Limestone Cement. This type of cement is better for theenvironment and cheaper than Rapid Hardening Cement which is used today at SträngbetongAB.Strängbetong AB isvery interested in a change of cement in the factory and wants to know what ittakes to make a transition from Rapid Hardening Cement to Byggcement.This final projectaims at investigating how the workability and strength development are affectedby a transition from the existing cement to Byggcement and how we can change theproperties of the concrete by adding different types of superplasticizers. Laboratory and factoryexperiments were made, to investigate the transition..

Samverkan mellan nya cementtyper och tillsatsmedel för betongtillverkning

Cement manufacture accounts for 3-5 percent of total global carbon emissions. There is a growing interest in reducing the environmental impact and conserve limited natural resources. In cement production, clinker productions consume 87.5 percent of the total energy consumed in the cement manufacture.Cementa has since many years, focused on reducing the environmental impact of cement production. The work has involved the entire production process from selection of alternative fuels to the development of cement with less clinker content. During 2013/2014, two new types of cement (Bascement and CEM II / B) will be introduced to the Swedish market.

Fanns det en elit på Gotland? : en studie om romersk järnålder på Gotland med fokus på romerska föremål

The purpose of this bachelor?s thesis is to examine whether there was an elite on Gotland during Roman Iron Age or not. To explain this focus has been put on the roman goods. The contexts in which the roman artifacts are found indicate that they can be tied to what might have been an elite on Gotland during Roman Iron Age. They might also have been used as means of expressing wealth and prestige.

Korrelation mellan hållfasthet i kalkcementpelare och oförstärkt lera : En studie av sonderingar utförda på projekt BanaVäg i Väst

A today common soil reinforcement method is the installation of lime-cement columns. Lime-cement columns have been used since the 1970?s and have been a useful method for stabilizing soil at great depths. It is mostly used for stabilizing road and railway embankments because the method is economically viable and the columns are easy to install. The total costs for the installation of the lime-cement columns is dependent on the numbers of installed columns, what percentage of lime and cement that has been used and the pattern in which the columns has been installed.

Lukas och Rom - En studie av evangelieförfattarens framställning av imperiet och dess folk

The purpose of this study was to see how Luke depicted the Roman Empire and in particularits people through his gospel. Around the time of the gospels? composition, 70-80 A.D., tensions were high between the Jewish people and their Roman occupants. However, it was during this period of high tension that a small group of Jews distinguished themselves not only by claiming that the promised savior, the Messiah, had arrived but also by including non-Jewish members into their ranks. The stated question is how this group of Christians reasoned both among themselves but also with their surroundings.

Integration, separation och allt där emellan - En studie om romska barns skolsituation

Our purpose was to investigate the schools and the social welfare´s experiences of Roman children´s school situation in a Scanian town. We have done a qualitative investigation, interviewing 14 persons from both school and social welfare. Through the interviews we wanted to find the factors which influences the Roman pupils schooling and which efforts the professionals has to their disposition to influence these children´s school situation in a positive direction.The main result of our study is that the majority of the Romans is an isolated group, both in the Swedish school system and in the society. The Romans got access to the Swedish comprehensive school first in 1965, which implies that the Romans have a young school tradition. Most of the Roman pupils have a high absent, which is grounded in a complex of problems.

Vattnets väg genom en romersk stad. -Från vattenkastellet till mottagaren.

The purpose of this paper is to make an analysis of the urban Roman water system. I have chosen to work with the system as a general field, not as a case study of a single town. In my opinion such a study would not give a proper and fair view of the subject. Therefore, this paper will discuss the different parts of the system, each one for itself and name examples wherever possible, to give a wide survey of the reality of the Roman water supply system. The aim is to give the reader a clear picture of different solutions used in the time of the early Roman Empire and a good understanding of the subject..

En Adaptationsanalys av Oscar Wildes roman 'The Picture of Dorian Gray' och David Rosenbaums film 'The Picture of Dorian Gray'

Romska barn och ungdomars syn på utbildning                                             : En intervjustudie

The purpose of this study is to understand how roman children and young people?s relations are to school and education from a family point of view.I have used a qualitative method and by means of that studied different information sources.  I have proceeded from two different theories: culture conception and categorizing. My first theory choice - Culture conception - represents a value of how we see the culture and the prospective of it.My second theory choice ? categorizing ? represents that we humans classify consciously or unconscious ourselves and others into categories, with the consequence that we understand the world by categorizing. Question I have proceeded from are: - Which roll does the family has for children and young persons from roman society? - Which expectations do children and young persons from roman society have from the family when it comes to education? Throughout my study I have come to the conclusion that roman culture looks differently upon boys and girls.

Marginal missfärgning hos ett adhesivt resincement jämfört med två självadhesiva resincement

Sammanfattning Inledning: Det finns olika helkeramiska material på marknaden idag. En av dessa materialgrupper är glaskeramer som framställs genom pressgjutningsteknik. För att öka frakturresistensen hos dessa keramer cementeras de med adhesiv cementeringsteknik. Genom etsning och silanisering av keramytan skapas mikromekanisk och kemisk bidning mellan keram och cement. Risken för missfärgning av cementskarven beror på ett flertal faktorer, däribland bindningsstyrka, cementskarvens tjocklek samt cementets abrasionsresistens och löslighet i munvätskor. De adhesiva cementen är mycket teknikkänsliga. År 2002 introducerades de självadhesiva cementen genom RelyX? Unicem.

Inverkan av delmaterialensvariationer på betongensegenskaper

Vid betongframställning förekommer det spridningar i delmaterialens egenskaper som påverkar den färskaoch hårdnande betongen. Spridningarna i betongens delmaterial har studerats hos tre av Skanskas betongfabriker(Göteborg, Luleå och Norrköping), genom provuttag som analyserats hos Cementa Research.Provuttag har gjorts en gång per månad under ett års tid från fabrikerna. Delmaterialen som har analyseratsär ballast, cement, flytmedel och kalkfiller (endast hos Göteborg och Norrköping). Siktning av ballast0-8 mm har utförts med den traditionella siktningen. För kornstorlekar mindre än 0,25 mm, cement samtkalkfiller har lasersiktning använts.För att få en överskådlig bild över spridningarna hos delmaterialen har en analys utförts som illusteraravvikelserna med exakta siffror.

Att skydda sig mot onda ögat -fallossymbolen och andra beskyddande symboler under antiken.

As long as envy and the will of harming others for what they possess have existed, the evileye has been a present belief system in many cultures around the world. This study, based onarchaeological evidence and texts by ancient writers that reflect this ancient superstition,explores how the evil eye was being averted and practiced by ancient cultures. What measureswere taken to ward off the evil eye? How have these measures been represented in thematerial culture? What can we learn from the context of the material culture involving the evileye? Discussions and theories of protective measures that have been depicted on the walls ofthe roman city of Pompeii will hopefully give a wider comprehension of the evil eye, and its influence on Roman society..
