Skapa ett framgångsrikt förbättringsarbete på AKzo Nobel Surface Chemistry i Stenungsund
Dagens omgivning är full av osäkerhet, marknadssvängningar, geografiska förändringar i arbetskraft och den högteknologiska utvecklingen vilket utsätter nutidens organisationer för ständiga förändringar (Savery och Luks 2000). Detta innebär att företag på 2000-talet, genom att systematiskt förbättra verksamheten, oavbrutet måste hålla ner kvalitetsbristkostnader, minimera förluster och öka produktiviteten för att kunna bevara sin position på marknaden (Baghel, Bhuiyan och Wilson, 2005).I denna studie var syftet att skapa ett nytt arbetssätt och struktur för ett framgångsrikt förbättringsarbete på Akzo Nobel Surface Chemistry Stenungsund. Studien bestod dels av ett teoriavsnitt med en litteraturstudie utifrån nutida forskning och även en kvalitativ undersökning genom djupgående intervjuer med 19 medarbetare från olika ansvarsnivåer och via en enkätundersökning som gick ut till resterande medarbetare.Akzo Nobel Surface Chemistry är en del av Akzo Nobel koncernen som är en av världens ledande färgtillverkare. Koncernen har över 55 000 anställda i över 80 länder där ungefär 3600 anställda arbetar på ett 20-tal platser runt om i Sverige. Företaget bedriver förbättringsarbete genom daglig uppföljning ute i fabrikerna och på respektive avdelning.
Hållbar utveckling i svensk planeringspraktik : en diskussion kring förtätning och andra ambitioner
If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.
Översvämningsmodellering av ett dagvattensystem
Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.
Fruktosamin som markör för diabetes mellitus hos katt :
Diabetes mellitus is characterised by persistent hyperglycemia in all species. Fructosamine is a glycated protein reflecting blood glucose concentration during the preceding weeks. It has become a valuable analysis to differentiate persistent hyperglycemia from transient stress induced hyperglycemia in cats. It is also used to evaluate current therapy in diabetic patients. Although fructosamine is a well accepted analysis, it is sometimes regarded with scepticism.
Nursing technique and growth environment of Rabbit fish (Siganus guttatus) in the area of Tam Giang lagoon, Thua Thien Hue
SummaryIn the area to the east of Hue city, in Vietnam, lays Tam Giang lagoon, one of Asia's largest lagoons, with an area of 22,000 hectares. This lagoon is suitable for aquaculture. One reason for this is because the salinity differs from sweet to salty in different parts of the lagoon. The Vietnamese Government advocates an increase in environmentally-friendly aquaculture and the fish Siganus guttatus (Rabbit fish) is a candidate for this. This fish eats mainly algae and can be cultivated in a polyculture.
NEDKYLNING HOS VANLIG B?NA, PHASEOLUS VULGARIS
Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.

Thecompany was contacted by the Swedish Defense Materiel Administration (FMV) in order todevelop a new system that would conform to their specific requirements. Two students at theRoyal Institute of Technology (KTH) were consulted in conjunction of this project in order to aidthe development and conceptual design of the system.The primary users of the system are the divers of the Explosive Ordnance Disposal division (EOD)- a branch of the Swedish Armed Forces. The purpose of the product was to incorporate allnecessary functions required by the EOD divers into one single system. The main functions arecommunication between the surface operator and diver, video recording, still imaging, positioning,navigation and ocean floor mapping with sonar.
Konstruktion av värmespridare med grafit för flygelektronik
This master thesis was carried out for Saab Avitronics, a business unit of Saab ABactive in electronic systems for military aircrafts. Reliability and weight are of crucialimportance in this environment. To improve reliability and lower the weight graphitemay be used for electronics cooling. Graphite is an anisotropic material and hasthereof high thermal conductivity in two directions (in-plane) and a relatively lowconductivity in the third direction (through thickness).The purpose of this thesis was to investigate if graphite is an adequate thermalconductor to use in PCB carriers. The carriers support and cool the PCB by divertingthe heat dissipation from the PCB components to the edge.
Kontinuerlig temperaturmätning i bädden på gratevagnar
Luossavaara-Kiirunavaara Aktiebolag (LKAB) är en gruvdriftskoncern med järnmalmsbrytning som huvudsaklig verksamhet. En av produkterna tas fram genom att raffinera järnmalm till pellets vilket är en efterfrågad produkt vid ståltillverkning. Vid sintring av råkulor till pellets är temperaturen väsentlig för att få så hög oxidation som möjligt av magnetit till hematit och för att få rätt fasthet. För att reglera värmen bör temperaturen mätas bland råkulorna eftersom det är kulornas temperatur som är det viktiga. Projektet går ut på att undersöka möjligheterna att mäta temperatur bland råkulor på gratevagnar som åker genom en pelletsugn med ett permanent mätsystem. Här ställs höga krav på mätsystemet på grund av miljö, portabilitet och drifttid.Miljöanalyser gjordes för att ta reda på vilken påfrestning ett mätsystem bör klara av. Förslag om placering av mätutrustning framtogs genom kartläggning av miljön.
Försämrad korrelation mellan storleken av Kebnekaises sydtoppsglaciär och andra klimatindikatorer
Intergovernmental Panel on Climate Change (IPCC) recognizes glaciers as the best land-indicator of climate change. A variety of studies have concluded, using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the summit-glacier constituting Kebnekaise's south summit (called the Southern-summit henceforth), Sweden's highest point, is studied to see how it is affected by winter precipitation and summer temperature during the period 1968?2013.
Skillnader i kungsörnens (Aquila chrysaetos) flyttningsmönster beroende på ålder och klimatfaktorer : En studie för skyddet av kungsörn
This study examines the factors that influence the seasonal movements of Golden Eagles (Aquila chrysaetos), and can thus provide important information that helps to improve the protection of the species. There were two main purposes of this study. First, I wanted to analyze the difference between preferences of juvenile and adult Golden Eagles in their choice of southern or northern hibernation areas. Do younger eagles prefer moving longer distance to southern areas of Sweden? Second, I wanted to investigate how the climate influenced the choice of date of migration in the fall.
Fuktkvotens inverkan på oljeupptag och pigmentinträngning i tall (Pinus sylvestris L.) och gran (Picea abies L. Karst) vid impregnering med Linotechmetoden :
Wood has always been an important material for people, and it is used for many applications. As for example, fuel for cooking and heating houses, construction materials and for constructing means of transport. Since wood also is a material that with time biologically degrades due to activity by micro organisms and wood fungi it is important to find ways to protect and further lengthen the life span of the material when in service. One method is to decrease the amount of water in the material by impregnation with an hydrophobic oil. The Linotech method which uses only pure linseed oil is one such possible method.
The aim of this study was to investigate the possibility to at the same time impregnate and stain/colour wood samples of pine and spruce by using the Linotech method.
Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Fallstudie av produktionschefers ledarskap
The thesis presented in this report has been made on behalf of Scania and their basic frame design department with the subject to solve an implementation of a weight sensing system in the chassis. The system is supposed to be implemented in the seat springs, and the reason for this is that all the force will have to go through the weight sensing transducers. With all the force going through the transducers the weight sensing system will not be sensitive for the differences in tolerances from manufacturing. The transducers could be pre-calibrated to avoid a calibration of the whole vehicle after it?s completed from the manufacturing line.Weight sensing systems is today a reality in trucks with air springs.
Metanpotential för alger och bioslam blandat med pappersfiber
In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas.Biogas production is a complex anaerobic digestion process in which various microorganisms decompose the substrate in steps and at the end produce biogas and a residue. Many factors affect the production of gas, for example the substrate content, temperature and pH in the digester.The analysis of methane potential were divided into two experiments. In experiment 1 substrates were digested along with inoculum from Växjö waste water treatment plant in a temperature of about 37 ?C.
