Fortplantning och fortplantningsproblem hos tikar av svensk och finsk lapphund : en jämförande studie

The Swedish Lapphund is one of our eleven Swedish domestic breeds of dogs and one of Sweden?s oldest dogbreeds. The Finnish Lapphund?s origin and physical conformation is similar to that of the Swedish Lapphund. One aim of this study was to examine whether the average litter size differs between these two closely related breeds, and if so, try to find causes for this.

Metoder för prediktion av kardiovaskulär sjukdom med njurfunktionen

This study examines if the prediction of cardiovascular disease in hypertensive patients can be improved upon when renal function and microalbuminuria are added to the classical risk factors The predictive capability of a model is measured by discrimination, calibration, reclassification and Harrell's C.The results are ambigious. In most cases, microalbuminuria should be included in the model, but the results regarding the other measures of renal function are varied. Therefore, the selection of risk factors to include in the model depends on which measure of prediction one prioritizes..

Light or Voice ? make your choice! : Plocktekniker för tillverkningsföretag

Companies constantly strive for the perfect order which enables them to satisfy and retain their customers. This is a difficult process that can be facilitated by using different picking technologies. In this study, a research of the picking technologies Pick-to-Light and Pick-to-Voice have been made to investigate when each technology is suited.In order to collect relevant information and data to be able to answer the question formulation, a qualitative study with interviews have been made. The purpose of this essay was to investigate Pick-to-Light and Pick-to-Voice to see when each technology is best suited and to see what the differences between the technologies are. With our essay we wanted to help manufacturing companies to make the right decisions when implementing a picking technology.The results showed that those picking technologies give companies a higher picking quality and an increased work efficiency since the order picking is faster to perform, and that picking errors are reduced.

Validering av ELISA för analys av equint IL-1 RA i plasma

Detta arbete syftade till att validera en metod för analys av interleukin-1 receptor antagonist (IL-1 RA) i plasma från häst. Med en fungerande analysmetod finns möjligheten att använda IL-1 RA som biomarkör för antiinflammatoriska effekter av läkemedel exempelvis dexametason. En kommersiell ELISA framtagen för analys av IL-1 RA hos häst användes vid valideringen. Analysmetoden var tidigare endast validerad för analys av IL-1 RA i spädningsmedium från tillverkaren. Vid validering av metoden framställdes standardkurvor i spädningsmedium från tillverkaren (reagent diluent=RD) samt i olika biologiska medier från häst. Beräkning av standardkurvorna utfördes med hjälp av linjär regression och innefattade intervallet 0,313 ? 20 ng/mL.

Gallringsprioritering av contortabestånd :

Extensive planting of the tree species lodgepole pine (Pinus contorta var. latifolia) during the 1970s and 80s has resulted in large areas now being available for commercial thinning. However, the varying quality of the stands creates a problem. The purpose of this study was to investigate, at the Torsby district of the Stora Enso forest company, how well the present computer records of the stands correspond to reality and determine which stands are, from a qualitative perspective, suited for timber production. Finding variables that indicate better stands would give Stora Enso the possibility of selecting qualitative stands which are more profitable to thin. The study included 32 stands containing at least 70 % Pinus contorta.

BAJT : Digital teknik i hemmiljö

The northern province of Sweden has in both literature and film been depictured as something foreign and mythical, unlike the rest of the country. It has been my purpose to show in this essay that the systematic categorization of Norrland and its literature reveals multiple criteria known to define the colonial era. By reading the novel Stallo by author Stefan Spjut with postcolonial structures in mind I aim to show how the author uses Swedish mythology and through the presence of The Other criticizes colonial structures in place to this day. By examining the gothic atmosphere I intend to indicate how the trolls in the novel figures as both a horror element as well as a representation of nature itself. It is my belief that the author by further reinforcing the mythological in relation to Norrland addresses the problem at hand.

Soliditetens betydelse för goodwillnedskrivning under ekonomiskt ansträngda perioder : En studie av den svenska finans- och industrisektorn 2008

Background: The international accounting standard regarding goodwill gives opportunities to several accounting procedure choices, as goodwill is a complex, intangible asset. The valuation of goodwill affects equity/asset ratio and income statement, which gives that the stakeholders? impression of the group?s financial statement is affected by the valuation of this asset. It has been pointed out that difficult economic times bring impairment loss to the fore. During financial crisis, equity/asset ratio may be significant as the economy of the groups is expected to be strained.Purpose: The purpose of this essay is to explain the appearance of the possible relationship between a group?s impairment loss for goodwill and their equity/asset ratio, during financial straits.

Konstruktion och design av hjul

The task given to us was to develop an industrial wheel with new thinking in terms of fresh design and construction, with the ability to brake. While the produced wheels of today only own the property of total braking, a wish was made to integrate the ability of directional locking.The time spent working with the project has been filled with multiple sketches of ideas and function analysis.Choices of material and ways of construction have been verified by calculations, tests and prototype building. The goal of this thesis has been to develop a unique caster with well thought-out design that would be adaptable to different areas of applications.The result was a hubless wheel with the ability of directional locking before total braking.A prototype of the wheel has been made to show the design and functions..

Integrerade ledningssystem : Drivkrafter, möjligheter och hinder

The world is changing and the business context is no exception. One of the clearest tendencies is a tougher business climate with harder competition due to increased international trade and the expansion of the e-business. At the same time the customers are becoming more sophisticated and demanding. The last decades have also meant that tougher and more frequent demands are being aimed at the businesses from a wider variety of stakeholders; demands regarding how environmental issues, social responsibilities and business ethics should be dealt with. All of the above have driven companies towards implementation of different management systems to be able to cope with the demands as well as to ensure that these issues are being dealt with in an efficient and effective manner.

Kan risken för finansiell kris förutsäga första dagens avkastning vid börsintroduktioner?

This thesis studies the relationship between risk and the first day returns of Initial Public Offerings (IPO) by assessing the risk of each issuing company with a risk model that combine financial key ratios of importance. The study is based on 92 IPO?s that were made on the Stockholm OMX stock exchange during the period of 1997-2009. The point of departure was to investigate if the uncertainty created by the asymmetric information between investors and the issuing firm could be captured by predicting the possibility of failure in the future. This has been studied by applying Skogsvik?s probability of failure model on the 92 issuing firms.

Är det utsidan som räknas

In this essay we have approached the problem with retailer brands that copy marketing leaders to get consumers attention in the storeshelf. We have sought to explore how much a designed package would change the consumers opinion of a brand and if this effect is different depending on if the brand is a retailer brand or a market leader. Also we sought to find if this effect would be greater with a salient color on the package. We made a quantitative study and with regression analysis we found that a designed package did have effect on the consumers opinion of the brand, and that the design with the salient color made the biggest effect..

Gravitationslinser

Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..

För ändring. En undersökning av tidningen i iPadformat

My work has been to create a magazine for iPad to explore this format, whichthere are mixed feelings about. Instead of seeing the digital format as an enemy ofthe printed magazine, I have chosen to see it as an opportunity.I have given myself the task of designing a magazine that can justify the useof the digital magazine. I have looked at the identity of the magazine, but mainlyexplored the format and its prerequisites.I was triggered to do the project when I saw people who are just making a pdfof the printed magazine and publish it digitally. I have during my work discoveredhow near or far away you can be from the printed magazine.The format of the iPad has multiple aspects to look upon; one that turned outto be clear in my project was navigation. Working with a spread has its problemsand opportunities; the same applies to an article that is larger than a screen.

Utbildningskvalitet : En undersökning av synen på utbildningskvalitet hos säljare och kunder av företagsutbildning

The Sub-Saharan countries have for a long time struggled with poverty and conflicts which might have proven hostile for investors. The analysis aims to see if there is a significant correlation between foreign direct investments (FDI) and economic growth and which cultural and institutional factors seem to be significant in this correlation. Considered are also other variables and their influence that might explain what motivates and gives incentives for foreign direct investments (FDI) and are used in the construction of a regression analysis. This to see whether there is an effect on the economic growth in relations to FDI. The results show that FDI is of significance to the economic growth in the region and the study shows that corruption seems to be the most significant institutional factor in the correlation with effect on economic growth and the ability to attract FDI..

Visar feta kiselalger på näringsrika vatten? : en undersökning om hur fosforhalt påverkar kroppsstorleken hos artkomplexet Fragilaria capucina

Syftet med denna uppsats är att undersöka om det finns någon mätbar korrelation mellan kiselalgskomplexet Fragilaria capucinas storlek och halten av fosfor i det vattendrag där de lever. Om ett samband finns kan detta efter ytterligare studier komma att bli användbart inom miljöövervakningen då bland annat vattendragens eutrofieringsgrad ska undersökas. Studien baseras på arkiverade kiselalgspreparat som finns på Institutionen för vatten och miljö (IVM). Arton prover med varierande fosforhalter valdes ut, och tjugo F. capucina räknades i varje prov.
