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..

Vad är en framgångsrik kampanj? : En studie av branschens syn på PR- och reklamkampanjers effekter

The study also includes if there is any difference between the framing due to the location of the newspaper. The study is based on qualitative text analysis. The theoretical basis is representation, framing theory, media image, media logic and a few conceptions from crisis communication theory.

Service-Dominant logic i B2B kontext : Hur skapa mervärde på en eftermarknad

För att på ett effektivt sätt uppnå konkurrensfördelar på dagens marknad krävs det att företag finner nya strategier för att bli konkurrenskraftiga, en strategi är att verka på en eftermarknad. Företagskunder utgör en mindre marknad och beroendet mellan parterna är större (jämfört med privatkunder) påvisar detta att relationen är en viktig del i en B2B-miljö. Service-Dominant logic (S-D logic) beskriver hur ett paradigmskifte sker där kunden betraktas som värdefullt humankapital och företag vinner konkurrensfördelar genom långsiktiga relationer, värdeskapande tillsammans med kund och utbyte av kunskap genom interaktivt processarbete. Syftet med denna studie är att undersöka på vilka sätt företaget Komatsu Forest kan vinna konkurrensfördelar genom att implementera S-D logic. De strategier vi testar är front-line employee (FLE) ? personal med kundkontakt, butikslandskapet, varumärket och den interna kommunikationen.Studien baseras på kvantitativa studier med en kompletterande kvalitativ studie.

Tjäderns (Tetrao urogallus L.) vinterdiet i norra Sverige : är gran (Picea abies) viktig i vissa habitat?

In Scandinavia, capercaillie are often associated with pine trees (Pinus sylvestris) in winter, with pine needles as the main diet. Few dietary studies have been conducted in Sweden and winter diet is subject to little debate. The interesting thing is that this "pine specialist? is also found in spruce (Picea abies) forest habitats where pine is scarce or unavailable. In many studies outside Sweden (primarily Central Europe) spruce is regularly observed in the winter diet, but I have found no reports on the selection of the diet in spruce forest areas in Sweden.

Clover (Trifolium spp) gamefields : forage production, utilization by ungulates and browsing on adjacent forest

Wildlife is a valuable and renewable resource that promotes economical, ecological and social values. These values are important for developing and maintaining many rural societies. However, growing ungulate populations have led to increased browsing pressure on valuable forest trees and crops. Previous studies have proposed supplementary feeding and gamefields as potential methods for controlling the ungulate foraging and reducing browsing damage by providing other attractive food resources. However, quantitative estimates of potential biomass production of various gamefield crops and browsing pressure on the surrounding forest have been lacking.

Chachaklum, a viable initiative? : a stakeholder management approach towards a community enterprise

Due to poorly functioning local and regional markets, the smallholders in San Francisco, Petén, were dependent on intermediaries that took advantage of the smallholder?s distance to markets. In an attempt to secure income and strengthen their bargaining position, 189 smallholders joined forces through the creation of a social smallholder network, held together by a community based enterprise. This enterprise was initiated in 2011 with the help of government incentive programmes and NGOs that within a few years will leave the enterprise to auto regime. This study treats the sustainability of a community forest based enterprise, Chachaklum, in northern Guatemala. The study identifies factors that enable smallholders to organize themselves in order to obtain business practices that support an improved standard of living.

Skiktning och strukturell utveckling i unga naturlika skogsplanteringar: :

Multilayered woodland types are an important part of the urban forest. The knowledge how to establish and maintain such plantations are not as deep as other knowledge fields concerning forestry. Therefore this study has looked upon how to achieve multilayered structures in young nature-like woodland plantations. As a theoretical base for the study three different major knowledge culture have been studied that concerns the subject, ecology, forestry and landscape management/design. This three theoretical framework concludes that many natural processes strive in the opposite direction of multilayered structures in their youth.

Skogsvårdsentreprenörers uppfattning om SÖDRA som uppdragsgivare

Södra in Oskarström has the ambition to become the best client for silviculture contractors and another aim is that the contractors should feel a strong sense of community with Södra. Several factors play an important role in order for these ambitions to be realized. The purpose of this study was to investigate how the contractors feel about their business relationship with Södra. The study was conducted during the spring of 2015 through a questionnaire which was sent to all ten silviculture contractors working with Södra in Oskarström. Overall, it seemed like the contractors were satisfied with the collaboration.

Operation Moked : Sexdagarskriget ? Överraskning inom de israeliska luftoperationerna

The research regarding the six day war and the aerial operations named Operation Moked is extensive but there are certain shortcomings in the research that examines both the operation and the principle of surprise.The aim of this paper is to contribute to this research by utilising existing military theories on the principle of surprise in order to identify indicators that are representative of surprise.  These indicators are thereafter used in a study of Operation Moked in order to examine the extent of in which the principle was utilised.The result of this research goes to show that the principle of surprise was utilised in great extent by Israel during Operation Moked..

Jordlöparfaunan i bestånd av contortatall (Pinus contorta) och svensk tall (P. sylvestris) 1987 och 2010

In the 1970´s the North American lodgepole pine (Pinus contorta) was introduced to Sweden in large scale. The lodgepole pine affects its new environment different from Scots pine (P. sylvestris), leading to a change in biological diversity. Forestry today affects the ground beetle fauna (Carabidae). Habitat specialists associated with older forests are first affected. When the canopy closes again after a clear-cutting species that prefer open habitats reduces and those who prefer mature/closed forests increase. In this study we compare differences in diversity and community structure of ground beetles in stands of lodgepole pine and Scots pine.

Stopover duration and field site selection by whooper swan (Cygnus cygnus) at Lake Tysslingen, Sweden

The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.

The legacy of the mill : a metal polluted forest soil in Gusum

Soils in a metal contaminated site on Stångberget in Gusum in southeastSweden were investigated and compared to relatively unaffected soils a fewkilometres away. Pollution came from historical release of untreated flue gasesfrom a brass mill. The objective was to find information on how high the metalconcentrations are, if metals from the polluted soil affect the surroundings andif the metal contamination affects the microbial community. The soil wasinvestigated using several different methods, such as field XRF measurements,chemical analysis of metal, carbon and nitrogen content, pH, acid neutralizingcapacity, texture, soil depth, field leach tests, sequential extraction and microbialfunctional profiles. The study showed that copper and zinc concentrationswere above Swedish Environmental Protection Agency guidelines for lesssensitive land use on the entire investigated area.

Verifieringsplattform i SystemVerilog

Our task was to create a virtual test bench for verifying memory addresses in our commissioning body?s models. The purpose with the testbench was that it should be created in such a way that it would be easy to change the device under test without any major changes in the testbench.To solve the problem that the testbench had to be able to verify different devices we had to create a general enviroment for how the testbench had to be composed. By doing an analysis of which com-ponents that are usually included in a testbench and which components that were necessary in our project we came up with a generall enviroment for the testbench. Our result was a testbench with the follwing basic functions:* Read from a file that contains read and write operations to the Device Under Test (DUT).* Apply the stimulus to the device* Read the results from the device* Compare the results with wanted values* Generate a log file which contains information about the simulation result..
