Är variation i STFI-tjocklek ett bra mått på kartongs bulighet? : Are variation in STFI-thickness a good measure of uneven surface, bumpiness, on cardboard?

This degree project aim to evaluate if variations of the STFI thickness can be used to assess bumpiness on cardboard. During the project cardboard samples were measured using Bendtsen, PPS, a L&W formation tester, OptiTopo, Ambertec formation, the STFI thickness tester and a visual comparison. The different methods were then compared to see if there is any correlations between them. The results showed that the visual comparison and OptiTopo correlates. The STFI thickness tester shows however no correlation with the OptiTopo and visual comparison, thus aren't suitable measuring bumpiness..

Slamfärger och dess miljöpåverkan

The paint market of today is a jungle whit an enormous range of different paint types; there all has different properties and different compositions, some with big influence on the environment and some whit less influence on the environment. It could even be difficult for an expert to always know what should be used on which surface and what would be the best out of the environmental point of view.This work is not intended as a total review of all the manufactures range of colours; only as a deeper dissertation about distemper paint in general, in particular Falu Red Paint. Whit focuses on the environmental issues.The work is especially for those who are ready to paint but don?t know what paint they should chose and people that has a interest in paint and environment, perhaps it also could be of interest for professional painters even when there probably isn?t any big news for them. The information is compiled from the Internet and downloaded brochures from the Internet..

Säkert sittande - Ett produktutvecklingsprojekt mot Innovationsslussen i Västra Götaland

A thesis directed towards Innovationsslussen in Gothenburg about securing, improving and simplifying sitting on the toilet for patients with sitting difficulties. The primary target group for the project is patients who have had a stroke and as a consequence from that suffers from various kind of bodily paralysis.An overall goal was to design an aid that was comprehensive enough that the patient could manage sitting securely on the toilet without have a nurse giving physical support during defecation.Five conceptual proposals were developed and evaluated in consultation with Innovationsslussen and one was selected to be further developed.The result was an integrated support at the toilet that facilitates a good sitting posture which minimizes the risk of falling and provides comfortable support when leaning to the side. The product is divided in two with both a redesigned carryingsystem and a new type of support surface adapted for the purpose..

Några svenska virkesaktörers system för skoglig planering

The purpose of this degree project is to give an overview of the planning system of four Swedish forest companies. The involved companies are ATA TIMBER, SYDVED, BERGS SKOG and VIDA SKOG. The study is based on information from a literature study and by interviews with personals from the four companies. Each company is described to get a better insight of the companies work and what potential they have. The description of the planning process comes after that. The companies are described separate from each other and will be compared later in this essay.

Klinisk termografi som diagnostiskt hjälpmedel vid rörelsestörning hos häst :

Thermography is the assesment of the surface temperature of the horses body and it falls into the categori of physiological imaging. Thermography allows us to portray inflammation and changes in sympathetic tone in a graphical manner. The purpose of this study was to review thermography in equine medicine and to evaluate thermography as an aid in the diagnosis of lamness in horses. Thermography has been helpful to identyfy sprains, stress fractures, shin splints and soft tissue, tendon, ligamentous and nerv injuries and to monitor healing processes during rehabilitation. Routine thermography may reveal inflammatory responses prior to clinical signs. In present study thermograpy gave especially valuabel information in two cases. In one horse reduced blood flow in a. saphena due to a thrombosis were visualised and in the other horse bilateral thoracolumbal radiculopati was diagnosed.

Vilka blir effekterna vid införandet av BSC i en stor respektive en liten kommun?

How the running and controlling goes, vary on different municipalities, depending how the organization is constructed and what is being prioritised. There exist laws and directives which the businesses have to follow, but beyond this the organisations are quite free to prioritise and to decide what the best is for the community as a whole unit. The municipality has access to different tools which purpose is to help them running the organization as good as possible, so they can create a well-operated business. This is very important, regarding that the tax money should be spent in an effective way, and be able to do so it is required good and well-functioned system of control.A big change has happened when the instrument BSC (Balanced Scorecard) was introduced in certain municipality. In this essay the focus lies on two municipalities, Vellinge and Kristianstad.

Mekaniserad plantering med Eco-Planter i södra Sverige :

This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The work was an assignment from Södra Skogsägarna and the aim of the work was to investigate the economical and biological output after mechanical planting with Eco-Planter compared with traditional manual planting. Eco-Planter is a tool for mechanized planting, fixed at the end of the boom on a conventional harvester. The study confirms that manual planting is less expensive under normal conditions. However, the differences between mechanized and manual planting are not that big and with technical development and/or increased labor costs together with an improved work organization the system with Eco-Planter could be competitive. The biological output, e.g. planting result and survival rate, seems to be quite good.

Timmersorteringens inverkan på sågverksekonomin :

Modern sawmills are using the raw-material and the production-capacity more efficiently today, due to rising raw-material prices and higher production costs. Log sweepness has a negative effect on the sawn yield, for sawmills with straight-sawing. It is desirable that these logs could be sorted based on more criteria, if it increases value-yield and consequently the utilization of raw-material. Bow-heights over 1 cm have a negative effect on sawn yield, since the surface of the mantle cuts down in the sawn pattern. Some of these small bow-heights reduce the logs yield of value which affects the production planning negatively. Nearly half of all the Swedish logs have a bow-height over 1 cm.

Stjärnhusen i Gröndal : bevara och förnya stjärnhusens innergårdar

It is sixty years since Sweden's first star-shaped housing estate was built in Gröndal, a suburb of Stockholm. Olle Engkvist, the building contractor, was the driving force behind the residential area and it was designed by architects Sven Backström and Leif Reinius. The estate comprises detached star-shaped houses suited to a more hilly terrain and terraced star-shaped houses on the flat land. The eight gardens of the terraced houses form the shape of a hexagon. It is these gardens, designed by Sven Hermelin and Per Friberg, which are the main focus of this thesis. The buildings on the estate have recently been renovated and it is now time for the gardens to be restored.

Frigörelse av fosfor från färskt, fryst och torkat växtmaterial : ett laboratorieförsök för att öka förståelsen för fosfordynamiken inom växtodlingen

Phosphorus is the single most potent contributor to eutrophication of freshwater and has also been shown to contribute to the toxic algae blooms in the Baltic sea. The dynamics and paths of losses of phosphorus from arable lands are not fully understood. It is known that phosphorus can be lost directly from plant material to water. In studies where plant material has been subjected to several freeze-thaw cycles, large amounts of phosphorus have been lost. Most studies have been conducted under field conditions, with many factors effecting the measured losses of phosphorus, such as weather and type of soil. This study was performed in a controlled environment without the presence of soil. Instead of soil, small glass beads were mixed with the plant materials in vessels, to make possible homogeneous leaching with water through the mixture of glass beads and plant materials. In this study, clover, ryegrass and dry straw were cut to pieces, approximately 2 cm long.

Dragbrotschning av invändiga profiler

High-precision cutting in metal is very complicated, a lot of parameters affect the result: what geometries to be manufactured, surface roughness and tolerances to be achieved, batch size etcetera. When pull-broaching internal parts this might be even more important, than in any other cutting operation. Everything is machined in one single stroke and the general technology is built in to the tool, therefore big investments must be made to change the process. Milling for an example: one piece at a time is machined away, and a lot of parameters can be changed easily.It is very high pressure on the cutting-edge when the broach is cutting. To achieve the specified product and to avoid unnecessary toolwear it is essential to use the right cuttingfluid and the right cuttingspeed for an example.

Ytrengöring av alfa-diamond : En studie och urval av ytrengöringsmetoder för hårda beläggningar

Examensarbetets mål är att rengöra en diamantkomposit med en ytrengöringsmetod. Metoden skulle vara mera effektiv än den manuella sandblästring som används idag för att ytrengöra detaljen.Detaljen är liten och har ett vitalt spår som ska rengöras. Detta ställer höga krav på effektiva metoder. De metoder som tas upp teoretiskt i examensarbetet är bland annat blästring, trumling och laserrengöring. Ett urval av metoderna testades.

Forza TV? : debatten kring den medierade valkampanjen i det italienska parlamentsvalet 1994

During the 1994 Italian elections many things were new for the voters. A new election system, new parties emerging where old traditional ones were dying out because of long ongoing corruption scandals that were coming up to the surface. In all this one man, Silvio Berlusconi, a famous Italian businessman, stepped in and with his two allied parties Lega Nord and Alleanza Nazionale he swept away the nation in a never before seen election campaign. Many things have been said about the motifs and the way he prosecuted the election campaign for the Forza Italia. But what I try to see for this thesis is the awereness in the Italian print media from this particular period - how and if the debate about an in just electoral campaign existed in the country from the date Silvio Berlusconi entered ?the playing field? as he called it and up to the days of election..

Kunskapens rum - en studie av Orkanenbiblioteket

The aim of this master´s thesis is to explore how a library through it´s spatial distribution expresses, and is an expression for, a view of knowledge. This is done by an analysis of the Orkanen library at Malmö Högskola. Questions posed in this study are: What view of knowledge is mediated through the spatial system and in the shelving of books? What view of learning is expressed in the spatial distribution of functions and artefacts?The theoretical framework of this thesis has two fundamental features. One, which focuses on theories of social space, a part that is mainly influenced by the theories of space syntax.

En jämförelse av stickprovsmetoder vid mätning av radioaktivetet på en yta

This study compares the sample variance of the mean in a simple random sample (SRS) and a systematic sample from a surface. The study also compares the prediction error variance in a SRS and systematic sample from a random field. Recommendations are presented on which method to use in the clearance and exemption process in the nuclear industry. The results indicate that quadratic systematic sampling outperformed SRS in most instances and proved to be especially efficient in the presence of a long-ranged covariance function and high sampling intensity (i.e. short distances between observations).
