Fåglar i urbana miljöer : kvaliteten på urbana habitat och om beståndstäthet är ett bra mått på habitatkvalitet
The urbanization of the world is increasing. How it affects bird populations have been well studied during the last decade, and comparisons between urban and non-urban habitats have been carried out. A common method for measuring habitat quality is to calculate the population density. This method is easy to use, but have been criticized during the last couple of years. In this study, data of population densities was compared with data on reproduction success.
Faktorer som påverkade valet : En studie i blivande sjöingenjörers utbildningsval
Den svenska handelsflottan har de senaste åren varit utsatt för massiva utflaggningar vilket har lett till att många sjömän har fått gå i land eller sökt arbete under annan flagg. Trots problemen med utflaggning och en potentiell minskad arbetsmarknad har sjöingenjörsprogrammet de senaste åren inte haft några större problem att fylla sina utbildningsplatser. Framtiden är fortsatt oviss och konkurrensen från andra sjöfartsnationer ökar. Syftet med denna undersökning var att undersöka vilka bakomliggande attityder och förväntningar som gjorde att studenter år 2013 valde att börja studera på det fyra åriga sjöingenjörsprogrammet i Kalmar, samt att mäta inställningen till den allt mer krympande svenska handelsflottan. För att genomföra detta arbete användes en enkätundersökning där förstaårsstudenterna på det fyraåriga sjöingenjörsprogrammet utgjorde populationen.
Utveckling av HPLC-metoder för kvantifiering av nyckelkomponenter i en villkorad emulsion
Traditionally, rolling mills use emulsions based on a mixture of oil and water for lubrication. Since two years ago SAPA has been using (instead of oil) a synthetic lubricant so called conditional emulsion for hot-rolling of aluminum. This lubricant is water based and homogenous at ambient temperature, but switches to a two-phase system at heating above the cloud point.This project aims to validate and if necessary modify an existing HPLC method for quantifying two out of three key components (A, B and C) in the conditional emulsion. Attempts to develop a method to quantify the pH adjusting components, X and Y were also made. These two methods are required to optimize the lubricant.Due to the complexity of the components, it has been difficult to present a method for quantification, and HPLC with ELS detection was chosen after a long series of trials.

R?TTVIS OCH GENOMF?RBAR KOMPENSATION: En normativ studie om kompensatorisk r?ttvisa vid klimatinducerad territoriell f?rlust
Inom det normativa forskningsf?ltet har en debatt r?rande kompensatorisk r?ttvisa uppst?tt i ljuset av att vissa suver?na territorium riskerar att g? f?rlorade till f?ljd av klimatf?r?ndringarnas effekter. Vilken sorts kompensation en s?dan moraliskt distinkt f?rlust rimligtvis b?r f?ranleda relateras i h?g grad till huruvida k?randeparten i dilemmat uppfattas vara territoriets befolkning som kollektiv grupp (ett s.k. kollektivistiskt f?rh?llningss?tt) eller som enskilda individer (ett s.k.
Kundlönsamhetsanalys som avbildande kalkyl och medskapande praktik: En fallstudie av Billerud
In recent years, customer profitability has become a focal point of academic discussions on business performance. However, researchers remain divided as to how evaluation of customers ought to be conducted, resulting in uncertainty of how accounting systems should be adapted to prevailing conditions. This paper aims to investigate the application of customer accounting techniques and the role they play in the organisational and commercial context in which they take place. In a case study of Billerud, a Swedish company providing materials and services for packaging solutions, the interplay between customer accounting techniques and customer relationship characteristics has been examined through the application of a theoretical framework developed by Lind and Strömsten. Particular emphasis has been put on deviations from the prescribed pattern of the framework.
Parameterstudie av inneslutningsbildning och utvärdering av processföring för tillverkning av plastformsstål
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.

Holodomor i Sverige. Hur Sovjetunionen och h?ndelserna kring Holodomor fram- st?llts i svenska l?rob?cker f?r gymnasiet fr?n 1950-talet och fram?t
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.
Karaktärisering av hårdmetallpulvrets råvaror och dess påverkan på pulvrets flödesegenskaper
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.
KONTROLLBERÄKNING AV ETT TAKRAS PÅ EN TENNISHALL I NYKÖPING : En jämförelse mellan Eurokod och BKR
?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.
Utvärdering av försvarsspecifika radiovågformer
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.
Framtagning av normalt referensintervall för RDW och retikulocyter på hematologiinstrumentet ADVIA 2120
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. .
