This thesis has been performed at Uddeholms AB with the purpose to investigate theparameters affecting the formation of inclusions during the manufacturing of a low carbonmanganese-steel.A follow-up, steel and slag sampling and evaluations in microscope have been done for a totalof five heats.The results for each heat have been evaluated in relation to the theory from the literaturesurvey and suggestions for changes in the process to reduce the amount of inclusions whichhave a negative effect on the steel quality have been given.The project extends over a large process where many parameters affect the formation ofinclusions. However, a tendency that a higher addition of alloys seems to increase the totalamount of inclusions before and after the vacuum degassing is seen.The majority of the studied inclusions seem to approach the composition of the top slag aftervacuum degassing. Ladle glaze may cause the inclusions which had a different compositioncompared to that of the slag.A high or low ladleage together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted material.In machined material so called stringers were found. The main composition of those stringerswas pure alumina. Inclusions with a composition of pure alumina were not found in the liquidsteel, thus the pure alumina inclusions must be formed during the casting.

Metoden som under- so?kningen anva?nde sig av a?r en learning study, ett kollektivt samarbete mellan historiela?rare som riktar fokus pa? elevers la?rande. Genom utva?rderingen av det samlade datamaterialet besvarades underso?kningens fra?gesta?llningar Vilka a?r de kritiska aspekterna fo?r att elever i a?rskurs 8 ska kunna utveckla en ho?gre grad av historiemedvetande, och Vilka centrala punkter i undervisningens uppla?gg go?r positiv skillnad fo?r elevers la?rande? Resultatet visar att de deltagande pedagogerna identifierade tre kritiska aspekter som anses vara avgo?rande fo?r en undervisning med ma?let att utveckla elevers historiemedvetande: 1.

This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.

?Boverket? the Design Regulations in Sweden, also called BKR has for a long timebeen the mandatory standard that has guided and regulated construction design. Butat the end of 2010 BKR was replaced with Eurocode. This report deals with thecomparison of these two standards when it comes to wood construction. Duringwinter 2009/2010 there were many roof collapses due to excessive loads on theroofs across Sweden.

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.

Erythropoiesis is a complex and carefully controlled process which is mainly regulated by erythropoietin. Using flow cytometry cells in a blood sample can be analyzed one by one. ADVIA 2120 using flow cytometry for analysis of red blood cells (RBC) and reticulocytes. Red blood cell distribution width (RDW) is a component of the RBC method. RDW indicates size variation on erythrocytes and is measured as a percentage of the mean cell volume (MCV). By measuring the RDW anemia can be divided into makrocytic, microcytic or normocytic. Reticulocytes refract light more strongly than red blood cells because they contain some cellular debris. The number of reticulocytes in the peripheral blood reflects erythropoiesis in the bone marrow. The purpose of this project was that by approved methods to establish reference ranges for the parameters, RDW and reticulocyte counts.The individuals who participated in the study, n=124, were considered healthy and had varying ethnicity. Reference subjects had not donated blood the last six months and participation in the study was voluntary.The statistic evaluation includes examination of distribution, and reference ranges for both men and women were established using the 2.5:t and 97.5:t percentiles. The calculated reference interval for RDW was between 12.0 ? 14.3% and the calculated reference interval for reticulocytes was between 38.0 ? 112.8 x109 cells/L. The results showed a significant difference between males and females for the parameter reticulocytes was seen. The difference indicates that different reference ranges should be established for men and women (p<0,0001). No significant difference between males and females were seen for RDW (p=0,74) indicating that the same reference ranges can be used for both men and women. .

Denna kvalitativa studie unders?ker vilka motiv som ligger bakom gymnasieelevers val att l?sa ?mnet svenska som andraspr?k, sva, och vilka erfarenheter de har med flerspr?kighet i klassrummet. Studien har en fenomenologisk ansats d?r elevernas livsv?rldar och dess spr?kliga repertoarer anses p?verka elevernas beslut och f?rh?llnings?tt (Busch 2017). Detta inneb?r att elevernas uppfattning om ?mnet sva och deras inst?llning till flerspr?kighet p?verkas av deras tidigare erfarenheter.

Fastighetsregistret (The Cadastre) is a large and important information sourcesupplied by Lantmäteriet (the Swedish mapping, cadastral and land registrationauthority). Fastighetsregistret provides geographical information about the 3.2 millionestates in use in Sweden. Fastighetsregistret has a large number of users who trustthat the provided data is reliable, but experience shows that the data can have varyingquality. As a user it is not always possible to access more detailed information inorder to assess to what extent the data in Fastighetsregistret is reliable.The purpose of this master's thesis is to investigate the possibilities of a system with agraphical user interface that present, classify and visualize the quality of the data inFastighetsregistret. The defined user group for this suggestion is internal users atLantmäteriet who have a good understanding of Fastighetsregistret.

It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.

PDF-files are to become a native file format in all prepress supplier workflows during 2006. This will give an opportunity to automate and develop a more stream lined prepress workflow. It is desirable to secure digital files by preflight the files early in the process. The objective with this project is therefore to find software that can automate parts of the preflight process and also to build up a well-functioning preflight workflow for preflighting both PDF-files and native files.Meetings have been held with preflight suppliers to find a solution for how to automate parts of the preflight in the prepress workflow. Seven preflight software companies demonstrated the possibilities with their products and four of these were chosen for continuing working with.
