Hunner eller heruler? : Skånes kontinentala kontakter under folkvandringstid
The intention of this paper is to explore the contacts between the Swedish province of Scania and Southeastern Europe in the Migration Period. This has been done through comparative studies of four object categories. Parallels to glass, horse trappings, jewellery with inlays and sword decorations found in Scania have been studied in southeastern and centralEurope, as well as the cultures of peoples involved in the Migration processes. The conclusion is that contacts were upheld in several ways: through trade, exchange, alliances and gifts. Old trade routes along the Vistula were used in the south-easterly direction to the Pontic area but were changed to the Moravian Gatein the latter half of the period, while westerly routes probably worked most of the time.
Kontrollerad gjutprocess för renare stål
In a multi-year project at Swerea Swecast AB studies on influence of dissolved gas on inclusions have been made. The knowledge about these parameters could be used to increase the quality of the final steel casting. The purpose of this thesis was to closer examine the impact of the oxygen level on inclusions.The questions asked were:? What was the amount of inclusions at different levels of oxygen?? What was the size of these inclusions at different levels of oxygen?? What does the inclusions consist of at different levels of oxygen?This was studied by measuring and sampling, sample preparation and microscopic analysis using an optical microscope and a scanning electron microscope (SEM). Measurements and sampling was performed at Smålands Stålgjuteri AB in Eksjö and at Swerea Swecast AB in Jönköping.
Framtagning av ny lagerlayout för Emhart Glass
Emhart Glass tillverkar den utrustning som behövs vid tillverkning av glasemballage såsom glasburkar och glasflaskor. Förutom att sälja hela lösningar säljer de även reservdelar. I och med reservdelsförsäljningen har Emhart Glass stora lager och ett stort flöde av inkommande samt utgående gods. Utspridda lagerplatser i företagets byggnad samt flytande lagerplatser gör att företagets önskan om att plocka motorer utifrån FIFO- principen inte kan ske. Syftet med detta examensarbete är att genom kartläggning och analys av det fysiska och administrativa flödet av motorer ta fram en layout som förenklar och förbättrar plockning och spårning.
Historiska emissioner av bly och arsenik till luft från Åfors Glasbruk och deras konsekvenser för miljön.
Åfors glasswork was a company which started in 1876 and closed in 2012 due to the bad economical situation in the company. After its closure, the glasswork left behind contaminated soil with different concentrations of heavy metals such as, arsenic from arsenic trioxide, a chemical used to remove bubbles during the melting of glass, and lead oxide, a chemical used in the production of crystal glass. Crystal glass?s production occurred under 1921-1971, but emissions of lead into the air from Åfors glasswork continued until 2011, because of the artist Bertil Valliens? artglas was made in Åfors glasswork from 1970?s and onwards.The aim of this study was to estimate how much lead (Pb) and arsenic (As) that were released by Åfors Glasswork into the atmosphere during the operational period of the glasswork in comparison with how much of lead and arsenic were purchased for the company. Added to the assistance of the data from National Archives the variations in the activities of Åfors glasswork could be shown.

Rullarmering - Ett rationellt sätt att armera
This is a degree project performed at Halmstad University in Sweden on the subject carpet ofreinforcement. This project is developed in association with Celsa Steel Service in Halmstad.The purpose of this report is to investigate how much time that can be saved if carpet ofreinforcement is used instead of the traditional way to work with reinforcement and seewhat kind of parameters that is important between the choices. We are also going to seehow this product affects the situation for reinforcement workers from an ergonomic point ofview.Carpet of reinforcement is made by straight reinforcement?s bars that are welded togetherwith steel bands. These rolls are made at a factory with a machine that welds together thebars in determined centre distance, with desired dimensions after the constructionengineers? blueprints.
Möjligheterna för Casabona-systemet
Abstract New methods, techniques and tools for the building industry are constantly being developed and improved and launched on the market. The problem in the building industry development is not that the products are not good enough. The problem is instead that the existing construction companies do not choose to use these innovations, instead they continue to employ the technologies they already possess and master. This leads to the fact that the construction industry is, in the public eye, beeing seen as a conservative industry. AquaVilla is a company that basically produces houseboats.
Snedrekrytering och mansdominans som organisationskulturellt fenomen
The purpose of this paper is to present a possible understanding of why the company Tekola is segregated according to sex. In accordance to this purpose, an understanding of how the segregation affects the employees in relation to power, values and possibilities is discussed. The theoretical understanding is that the organization of men and women within Tekola is done in close connection to creation of the meaning of gender in Tekola. This, in turn, affects and is affected by the recruitment to and within the company. Through the study of statistics from a survey, five interviews with employees and former employees and Tekolas? equality plan, we are able to see the possible existence of a glass ceiling, and a culture of homosociality, which affects the possibilities of women to enter the company and also to gain full entrance to power-positions in a negative way.
Rätt fönster i olika väderstreck : En undersökning av energieffektiva fönsters påverkan på byggnaders energiprestanda
The Swedish building stock accounts for nearly 40 percent of the total energyconsumption in the country. Properties built today are likely to last for 100 years orlonger. This places high demands on long-term and smart energy solutions that willkeep the future Swedish building stock energy consumption at low levels. This thesishas focused on examining how the energy performance of buildings is affected bydifferent choices of window types in different cardinal directions. The objective wasto obtain a basis for recommendations on how window properties can be optimizedfor different types of buildings and orientations.
Utveckling av Pusher Finger
Emhart Glass är ett världsledande företag som tillverkar och utvecklar utrustning för hela processkedjan inom glasförpackningsindustrin, från smältugnen till efterbehandling och kontroll av de färdiga produkterna. Glasförpackningarna är mycket heta när de är klara och hålls därför ovanför en perforerad platta, Dead Plate, för kylning innan de transporteras i en båge ut på transportbandet som skickar vidare förpackningarna mot efterbehandling, kontroll och paketering. Den mekanism som utför transporteringen av glasprodukterna är uppbyggd av en elmotor och en luftcylinder. Mekanismen kallas Pusher 860 och kan tyvärr inte garantera en tillfredställande förflyttning. Glasprodukterna påverkas av centrifugalkraften vid den bågformade förflyttningen ut på transportbandet och hamnar sällan allihopa på en rät linje.
Handel med utsläppsrätter - hur företagsstrategier påverkas :
Climate change is one of the most difficult problems that humans have to deal with. Today, the evidence of human effects on the climate change and the rise of temperature on earth are strong. It is extremely important that all countries get together and cooperate in order to be able to solve the problem with climate change. One step in the work on climate changes is the Convention on Climate Change, which was agreed on in 1992. The Convention on Climate Change resulted in the Kyoto Protocol in 1997.
The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions.

GNSS-Styrning : Information för platschefer
An investigation of the heat impact of laser cutting on the material properties when producing tensile and impact test specimens of different steel types of varying thickness has been performed. The purpose of the thesis project was to provide recommendations regarding how much material that needs to be milled from the laser cut edge before tensile and impact tests. The study has been performed partly by investigating the test specimens by heat camera when the specimens were cut in the laser cutting line and partly by performing hardness tests, investigation by microscopy, and tolerance and roughness measurements and tensile tests of the laser cut material and material produced in the traditional multi operation machine. The results show that the heat affected zone in the thicker materials is greater than previously thought of, and that the currently used recommendation has to be adjusted. The study clearly shows that the thicker the material, the greater the heat affected zone, independently of the steel type, since the thicker material takes longer time to cut.
