Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell Phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

Mindre åkeriföretags konkurrensstrategier

The amount of cargo has since the 1970s increased in Sweden and the road traffic accounts for a large part of the transported volume. In Stockholm County the amount of cargo is calculated to be doubled in size from year 2001 to 2020 which means a greater need for transport is required. Much of these transports are being carried out by haulage companies of varying sizes which acts externally as carriers for their customers. All of this despite a greater awareness, laws and demands regarding environmental performance.The trend shows that the haulage industry in Sweden are moving towards fewer but larger haulage companies, which means that the competition is getting tougher for the smaller haulage companies. Smaller haulage companies and research about their competitive strategies is a neglected part of this industry.

Har det skett en kvalitetsförändring i och med avskaffandet av revisionsplikten för småföretag? : Kvalitativ studie med utgångspunkt från tre intressentgrupper

Title:Cash is King ? or is it?Level:Final assignment for Bachelor Degree in Business AdministrationAuthor:Caroline Eng and Jessica HillbergSupervisor:Jonas KågströmDate:2011- 06Aim:There is a long tradition of trading the currency and the first coins can be traced back to Persia already 500 BC. With the modernization of society and the technological advances we have made in recent years, we are now using electronic payments more and more. We pay by card, Internet banking and mobile Phone in addition to cash. The purpose of this paper is to follow Swedbank project "cash smart" and have it as a basis when we examine if we are heading for a cash-free society and what obstacles and opportunities there is for a cash-free society.Method:We have used a qualitative method to conduct interviews with two individuals involved in the project "cash smart" at Swedbank in Gävle.

Militära ?mobil-appar? : Den militära nyttan med kommersiell teknik för militära ändamål

The transformation of the Swedish Armed Forces is bringing about major changes in many areas. Indirect fire is one capability affected by these changes. Financial savings, a shrinking organization and higher eligibility requirements mean that fewer soldiers will gain access to exclusive high-tech support resources such as the JAS 39 Gripen aircraft and the ARCHER artillery system. This thesis aims to examine whether access to indirect fire capability can be increased through the use of civilian products and communication networks. Technology development in the civilian mobile communications area is exponential and nations such as the USA, facing challenges similar to those of the Swedish Armed Forces, devote substantial resources to research and development.

Från profit till ansvar, ett företags anpassning till verkligheten : en studie av användandet av ekologisk bomull inom H&M

In the last years people has become more aware of issues regarding corporate social responsibility. This has led to a more thorough control of big multinational companies, which are often held account of violating social, ethical and environmental values. The term most often used for this is corporate social responsibility (CSR). H&M is a Swedish multinational company and the concept of H&M is fashion to a low price. The material most often used in producing clothes is cotton.

Teknisk undersökning : Rötgaskammare för småskalig biogasproduktion

Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.

Användandet av smartphones bland studenter: en av 2000-talets källor till upplevd stress? : En jämförande studie bland män och kvinnor

Prokrastinering innebär att individen trots medvetenhet om negativa konsekvenser skjuter upp en handling. Den bidrar till stress, färre hälsofrämjade beteenden och sämre prestation. Demografiska faktorer och pågående utbildning påverkar sannolikheten för prokrastinering. Relationen mellan stress och prokrastinering behöver utforskas, speciellt hur interventioner riktade mot stress påverkar fenomenet. En longitudinell interventionsstudie med upprepad mätning undersökte effekten av ett KBT-baserat stresshanteringsprogram (KBSP) på prokrastinering och interaktionseffekter med stress.

Eftermarknadens möjligheter : En studie av Swecon AB:s tjänsteutbud

ProblemThe manufacturing industry is a mature industry where the profit margins are small and the competition is hard. This makes it hard for both manufacturers and resellers to gain market shares and reach reasonable profit margins only by selling products. Therefore Swecon who is reseller for Volvo Construction Equipment tries to find alternative methods and ways to increase their profit. An alternative source of income could be to develop the range of services that are connected to the ground products.PurposeThe purpose of the thesis is to examine how Swecon in southern Sweden can improve their offers of existing services connected to the ground product and investigate the demand of new such services.MethodThis study is based on a qualitative study of five of Swecons local offices and five of Swecons customers. The empirical framework is mostly based on personal interviews but in some cases information was retrieved by using Phone interviews.

Lärarens upplevelse av elevernas mobiltelefonanvändning i klassrummet : en fallstudie

Något händer när ny teknik gör intåg i klassrummet där undervisning, studier och lärande i olika ämnen står på schemat. I nästan varje elevs ficka finns idag en populär artefakt, mobiltelefonen.

Men hur anser lärarna att elevernas användning, kommunikationsrutiner och strategier för studier och lärande påverkar undervisningen och attityderna till skolarbetet? I skolan har man traditionellt alltid använt artefakter som myndigheterna har tillhandahållit, exempelvis böcker, penna och papper.
