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%.

Today multi-touch technology is the basis for many new techniques designed to improve interactions with computers and mobile devices. It seems that multi-touch screen interface makes the user handling very natural in the sense that there is no need for a manual in how to interact with the object on the screen. The aim with this paper is to establish a fundamental set of design principles intended specifically for large multi-touch interfaces. To reach this goal we have implemented a couple of sub-goals beforehand: It was essential that we acquired a good understanding of the current state of the multi-touch interface and the different implementations that exist today. To make this possible we constructed a multi-touch display, "Rosie". Knowing how the hardware is produced today will help us understand the limitations and also the possibilities of the design implementations today and in the future. We also needed to devise a sound interaction design process that conveys the modern designers work.

The project's aim has been to develop this system and to implement a server, a database, a website and a client application that simulates sensor signals.

Today many buildings and it´s nearby surroundings are designed to achieve some kind of environmental goal.The issue concerning energy consumption is currently at focus and it is relevant that we start increase the share of renewable energy. Solar energy is an infinite resource and should therefore be considered when selecting an energy supplier. Uppsala University hospital is facing major restructuring when parts of the existing buildings will be refurbished and a large new building will be constructed. White Architects have developed a study concerning the new building and for some of the existing buildings on the hospital campus. Uppsala County requires tough energy measures and wants the new building to be classified as an eco-building in Whites following work. The classifications will involve high energy source requirements. This work has been conducted to see if solar power can be envisaged as a supplementary energy source for the University hospital and also to investigate the aesthetic impact of solar cells on the new building.

The present thesis closer examines what has come to be known as al-Qaida, partly from what al-Qaida is considered to be, partly from the consequences a certain picture of al-Qaida might give rise to. Between 1988-2001 most of this thesis sources refers to al-Qaida as a small, organized core group with some degree of cell structure. From 1991 to present days, many of the sources enlarge the picture of al-Qaida. From now on they start to view al-Qaida as either a network in itself or al-Qaida as a part of a larger islamistic network, not only as an organized core group with presumptive bases in Afghanistan. The most recent of theories regarding al-Qaida looks at al-Qaida as an ideology in itself (al-Qaedaism) or al-Qaida as a part of previously existing ideologies (Islamism, Neofundamentalism and Jihadism-Salafism).Al-Qaida is being seen - by scholars, journalists and terrorism experts - as an organization with a core group, a network in itself, part of a larger islamistic network and an ideology of its own or as a part of already existing ideologies.

I denna uppsats undersöks ungdomars användning av gratis mobilapplikationer.

Under de senaste åren har användningen av mobilapplikationer i smartphones ökat och kommer förmodligen fortsätta att göra det. Smartphoneanvändare ställer ofta höga krav och vill nästan alltid ha bättre prestanda i smartphones vilket driver utvecklingen framåt. Dock har många smartphoneanvändare klagat på att batteriet inte räcker till för deras användning. Enligt olika forskare är inte batteriet dåligt utan det är mobilapplikationer som förbrukar för mycket energi. De flesta studier som handlar om energiförbrukningen i mobilapplikationer fokuserar mycket på de tekniska aspekterna och det finns relativt lite kunskap om vad användare tycker om energiförbrukningen.

It is important to know what is normal in the wound healing process in order to determine what happens when a wound does not heal as expected. If the amount of bacteria in the wound gets too large the body will not be able to defend itself and it becomes an infection. Colonization and infection are common elements in wound management and it is often the veterinary nurse role to deal with wounds in a proper manner. Antibiotics are drugs that either kill or inhibit the multiplication of bacteria or fungi, and have been in veterinary medicine for approximately 60 years. Very few new antibiotics are introduced and increased resistance is a major problem that requires everyone to take responsibility to reduce the use of it.

If customers respond differently to a campaign, it is worthwhile to find those customers who respond most positively and direct the campaign towards them. This can be done by using so called incremental response analysis where respondents from a campaign are compared with respondents from a control group. Customers with the highest increased response from the campaign will be selected and thus may increase the company?s return. Incremental response analysis is applied to the mobile operator Tres historical data.

Vid TCF-blekning av pappersmassa är väteperoxid en av huvudkemikalierna. I dagsläget är det svårt att styra blekstegen. Operatörerna måste ta hänsyn till produktionstakt, blekbarheten på massan varierar och fördröjning i trender. PO-bleksteget på Södra Cell Värö har en ungefärlig uppehållstid på 4 timmar och det är först efter så lång tid som man kan se hur en förändring verkligen slår igenom. Överblekning kostar väldigt mycket i kemikalieåtgång och det är därför efterfrågat ett sätt att kunna styra och optimera peroxidblekningssteget.

En sammanfattning av uppsatsen på maximalt 8000 tecken.This thesis is mainly dealing with the mobility of the employees within the borders of the European Union. Legislative framework from the EU is favourable and the Commission has set as one of it goals to promote the migration. Globalisation trends and contemporary business concepts need people who are mobile on the other hand. But migration numbers are still low within Europe. The purpose of this thesis is to find out how much the legal uncertainties, and the different culture mentality in the workplace of another country act as barriers in the minds of the people who wish to work abroad.

Investment costs for eight different type housing systems for dairy cows has been calculated in order to compare the building costs as a function of herd size, shelter type and automatization. A commercial calculation programme for building was used and complemented with prices of equipments specific for dairy cow building. Herd sizes were 120, 250 and 400 cows. The milking equipments were automatic milking system (AMS), parallel parlour with 32 stalls (2x16) and rotary parlour with 24 stalls. Shelter was either insulated equipped with automatic cable driven scrapers on solid alleys, automatic feed wagon on rails, or uninsulated with manual manure handling and a tractor driven mobile mixer wagon on a drive-through feeding table. Building cost per cow or per kg milk was calculated using an average life time and 6 % interest rate and annual milk yield is 9 500 kg/cow and year. Structure effect 3-4 % higher for an insulated structure than in an uninsulated for 400 and 120 herd respectively. This is much lower compared to what is normally argued.
