Swedish design is known all over the world and is seen in national as well as in international arenas. There is only one design organization in Sweden that has the task to represent Swedish design in public. The organization is Swedish Form and it is the oldest design organization in the world. It has a huge influence in our society, within design and form. In the end of 1990 the association received its first government assignment, which still continues.

When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of the fact that technical progress in the form of optimized engines and shifts in the means of transport sometimes result in even greater emission levels, other solutions to this problem must be studied to decrease the emissions of carbondioxide from the diesel trucks. The purpose of the thesis is to show how a decrease of the carbondioxide emissions from diesel trucks in Sweden can be achieved in a costeffective way by the use of a carbondioxide tax and a differentiated vehicle tax. The method used in order to fullfill the purpose of the thesis is studies of literature, mainly of public government reports. Literature of enviromental economics will be used to show the need of a tax and how to determine the dynamic effective carbondioxide tax in steady-state.

The aim of this study was to provide SCA Forest Norrbotten District with material to assist in their work towards decreasing the frequency of bucking splits in their saw timber logs. SCA Forest supplies the Munksund sawmill with pine timber. Periodically the sawmill experiences problems related to bucking splits in their logs. The purpose of this study was to find an available method to measure the occurrence of splits directly on incoming timber. The ambition was also to gain some knowledge about possible variations between different logging crews in terms of split frequency. If possible, this information could be used to investigate if certain crews produced more splits than others, and thereby making it possible to provide feedback to the logging machine operators. The study consisted of two major parts, a literature review, and a practical sawmill study.

In the western world, strokes are the third most common cause of death, hitting mainly the elderly population. Smoking, high blood pressure, diabetes and overweight are known risk factors for causing strokes. Previous studies show that an increased level of particulate matter, PM, is also related to an increased number of strokes. The population in this study consists of patients over 65 years old who live in Malmö. Levels of particulate matter were measured from October 2004 to April 2005 at a central outdoor monitoring site in Malmö.

Near Field Communication (NFC) is a short range wireless communication technology that enables data exchange between devices. NFC is used in many different areas, from subway tickets to authentication systems. This paper presents possible security threats to Near Field Communication and documented attacks that have been used to target various NFC protocols. Weaknesses in different NFC protocols will be presented and suggestions on how to counter certain weaknesses will be discussed. This survey will be valuable for companies interested in protecting their data when using or planning to use NFC systems..

Med detta arbete har jag försökt besvara frågan om progressiv form har ökat eller minskat i engelska skönlitterära romaner sedan 1813 till 1913 och vidare till 2001. Arbetet omfattar litteraturstudier avseende progressiv form och olika tempus i engelska språket. Mitt syfte var förutom att studera texter för att besvara frågan om frekvensen av progressiv form att klargöra vad progressiv form är och vilka tempus som finns, samt att besvara frågan om när man som språkstuderande bör vara medveten om vilken betydelseskillnad som föreligger då man använder enkel respektive progressiv form. Den tendens jag har funnit är att progressiv form har ökat från år 1813 till år 1913 och ytterligare till år 2001..

Short bowel syndrome (SBS) är ett tillstånd som uppkommer hos personer som har förlorat stora segment av tarmen vilket resulterar i malnutrition och de som har mindre än 2 meter tarm är mycket utsatta. Forskningen visar att det är många aspekter av livet som berörs för de personer som drabbats av SBS och det medför en förändrad livssituation för den sjuke personen. Förändringarna påverkar inte bara den som är drabbad utan även familjen, så som en partner. För att öka vårdarens förståelse för dessa partners situation är det viktigt att uppmärksamma och belysa deras upplevelse. Syftet med studien är att belysa partners upplevelse av att leva med någon som har SBS.

Att mäta patienters HRQoL (Health Related Quality of Life) är en viktig utvecklingslinje inom vård och vårdforskning. Medicinsk resultatmätning bör kompletteras med nya dimensioner för att kunna utvärdera patientens samlade nytta av behandling och vårdåtgärder. Mätningar är särskilt viktiga när det gäller kroniska sjukdomstillstånd. Syftet med denna studie var att undersöka erfarenheterna av SF 36 (Short Form (36) Health Survey) på enheter som deltog i Skåneprojektet. Metoden var en enkätundersökning med kvalitativ ansats.

Syftet med föreliggande uppsats var att studera inkluderade skönlitterära författarskap i läromedel avsedda för gymnasieskolans kurser Engelska 5, 6 och 7 med fokus på spridningen över kön och nationalitet. Forskningsfrågorna som studien utgick ifrån var:I vilken utsträckning förekommer författande kvinnor respektive författande män?I vilken utsträckning representeras olika nationaliteter genom inkluderade författare?Om så, vilka särskiljande, värderande eller likställande praktiker går att utläsa i hanteringen av författarskapen utifrån könstillhörighet och nationalitet?De första två frågeställningarna besvarades genom en kvantitativ innehållsanalys, medan den tredje besvarades genom en kvalitativ innehållsanalys. Studerade läromedel var fördelade över fyra läromedelsserier och var enligt följande: Worldwide English 5 (2014a), Worldwide English 6 (2014b), Echo 5 ? Short Stories (2013a), Echo 6 ? Short Stories (2013b), Viewpoints 1 (2011a), Viewpoints 2 (2011b), Viewpoints 3 (2011c), Pioneer 1 (2012a) och Pioneer 2 (2012b).Den kvantitativa innehållsanalysen konkluderade tre statistiskt tydliga resultat.

Problem discussion: Long-term supplier relationships have become more common. Hence, supplier evaluation is a critical activity for many companies. However, making a relevant supplier evaluation is time consuming. Therefore, it is important to decide which of the suppliers to put an extra effort on. Should all suppliers be evaluated in the same way? Previous, focus has been on purchasing of direct material.

THE THIN RED LINE ? Identity in theory and method With this essay I want to explore some possibilities with the term identity within archaeology. Identity is a term best understood in the light of different scientific approaches. For instance the anthropological and historical angel combined with the quality of archaeology, as is the case in this essay. By combining these approaches, I create a (clarification) method of exploring traces of identity.By analysing two different graves from Scania, having a negligible number of artefacts from the Viking Age, and three graves from Bornholm, known for its large number of finds from this period, I test the ability of my method.

 Car seats for smaller children, offers very good protection incase of a collision. Unfortunately for the parents? sake , these car seats is heavy to handle outside the car. For example back and forth home and short errands around town. In other words, all those times when you decide to just take out the car seat and carry it instead of place the baby in a baby carrier.

This candidate report describes how a group of students can develop a smartphone applicationwithout any prior knowledge in the field. To make the project more realistic there is also a clientwho has requests and wishes regarding the finished product.The document describes the methods used to produce the application and also includesexperiences that the group gained. How the interaction with the client has been performed togain a good understanding of what they wished the product to become is also accounted for.The research questions focus on how the development has proceeded and how one can learnsomething new in a relatively short timespan as a group..

In line with Sloan (1996) but on European data (STOXX 600) we are investigating whether stock prices reflect information about future earnings contained in the accrual and cash flow components. The extent to which current earnings performance persists into the future earnings performance is shown to depend on the relative magnitudes of the cash and accrual components of current earnings. Moreover, we still find a significant positive excess return (Jensen?s alpha and size-adjusted return) by replicating Sloans (1996) hedge portfolio by taking a long position in the stock of firms reporting relatively low levels of accruals and a short position in the stock of firms reporting relatively high levels of accruals. However, we find no evidence of negative excess returns for companies with relatively high accruals, this somewhat lower the total excess returns for all the portfolios.
