Samband mellan tjockleken hos PVD-skikt och förslitningsbeteendet vid svarvning
This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).

Har energidryck någon kognitiv effekt i kombination med alkohol? : Med fokus på komponeneten koffein
Background: Energy drinks have been found in everyday-stores since 1997 and their popularity have increased over time. Consumtion of energy drinks takes place because of their ability to increase concentration and to decrease fatigue but also because of the popularity the drinks have got. Target groups for these stimulating beverages are adolescents and young adults. Energy drinks contain caffeine, taurine, glucuronolacton, carbohydrates and B-vitamins and voices have been raised about the eligibility for young people to ingest large quantities of these kinds of substances. Because of the properties of these substances it has become popular to mix energy drinks and alcoholic beverages to make up for the negative effects of alcohol and to be able to drink larger quantaties.Aim: The aim of this literature work was to investigate cognitive effects of the combination of caffeine in terms of energy drinks and alcohol and to determine if these effects could be harmful.Method: This literature work is based on five scientific articles retrieved from PubMed.
Porcine viruses in Uganda : a study of TTSuV and PPV4 in wild and domestic pigs
Uganda has the largest pig population in east Africa, and most of the animals are owned by smallholders. Infectious diseases among pigs have a devastating impact on the livelihood of these farmers, which are dependent on the proceeds from pig rearing. In a metagenomics study of the wild pig species bushpig (Potamochoerus larvatus), the porcine viruses Torque teno sus virus (TTSuV) 1and 2 and Porcine parvovirus 4 (PPV4) were detected. TTSuV1 and 2 are ubiquitous in the world?s swine population, and PPV4 has been found in USA and China, but neither of them has been studied in Africa previously.

Val av energisystem för en hållbar stadsdel : En fallstudie av Östra Sala backe
Uppsala County has ambitious environmental aims for the planned residential area inÖstra Sala backe. In this thesis different energy sources have been evaluated todetermine which system that would be most favorable given currently availableinformation about the project. Planned energy usage has been divided into tap waterheating, space heating and power. Three base case scenarios were made with districtheating, small scale bio fuel and heat pump. Solar power and solar heating were thensimulated and the production from the two could individually be deducted from theenergy need in the base cases, constituting 9 different scenarios.

The Critical-Care Pain Observation Tool (CPOT) på NIVA : En enkätstudie om användbarhet
Bakgrund: Smärta är för intensivvårdspatienten en unik, subjektiv, obehaglig och flerdimensionell upplevelse. Intensivvårdssjuksköterskan har ett moraliskt ansvar att lindra patienternas smärta. Verbalt icke-kommunicerandepatienter kan inte skatta sin smärta med hjälp av Numeric Rating Scale (NRS). På en neurointensivvårdsavdelning (NIVA) i Stockholm har det beteendebaserade smärtskattningsverktyget- the Critical-Care Pain Observation Tool (CPOT), implementerats. Intensivvårdssjuksköterskorna på NIVA använder CPOT dagligen i sitt arbete.
Effektiva återkopplingsverktyg för elanvändning : En studie som syftar till att identifiera utvecklingsmöjligheter för att uppnå ett mer hållbart energisystem år 2030
Feedback tools support electricity users within the Swedish residential sector to increase their knowledge of electricity and the electricity market as well as to become more aware of their electricity consumption, which in turn encourages a reduction and an increased flexibility of electricity use. The primary aim of this study is to identify and analyse how existing feedback tools can be improved, to ensure that they contribute efficiently to the achievement of the EU objectives congruent with a more sustainable energy system in 2030, emphasizing: greenhouse gas reduction, increased energy efficiency and an increased share of renewable energy. In order to reach the primary aim of this study, existing feedback tools have been identified and mapped and interviews with feedback tools providers have been conducted. The study is limited to three research areas: the practical functions of feedback tools, available technology and the use of feedback tools.The use of more efficient feedback tools will provide an increased success rate for energy management, which includes both behavioural changes and energy efficiency. According to the results from the interviews conducted for this study, an increased use and user frequency is important to utilise the energy management potential.
?Ökad mobilitet, delaktighet och frihet ? IKT-stöd som fyller verkliga behov inom äldreomsorg : Behovskartläggning för kommunikation och information mellan omsorgstagare, närstående och utförare som grund till en gemensam kontaktyta
Allt fler blir allt äldre i Sverige och äldreomsorgen står inför en stor utmaning när resurser i form av ekonomiska medel och rätt personal blir allt svårare att konkurrera om. I eHälsans tidsålder utvecklas det på många håll smarta tekniska lösningar för att effektivisera och kvalitetshöja omsorgsinsatser, något som allt fler aktörer får upp ögonen för. Denna uppsats utreder behovsbilden för att kunna skapa en ny kontaktyta mellan omsorgstagare, närstående och utförare inom äldreomsorg. Uppsatsens resultat är en del av det Vinnova-finansierade projektet BoNUS VO som undersöker förutsättningarna för en sådan kontaktyta. IKT-stödet ska underlätta delaktighet i den egna omsorgen såväl som stödja yrkesutövare i arbetsuppgifter.
Problematiken med värdering och redovisning till verkligt värde : Kreditinstitutens användande av verkligt värde vid värdering och redovisning av förvaltningsfastigheter
Värdering till verkligt värde infördes i regelverket 1 januari 2005 i och med införandet av IAS 40. IAS är en förkortning av International Accounting Standards och IAS 40 ger börsnoterade bolag med förvaltningsfastigheter möjlighet att värdera och redovisa dessa fastigheter till historiskt anskaffningsvärde eller verkligt värde. Efter införandet har de flesta börsnoterade bolag valt att redovisa till verkligt värde.För att belysa problematiken med värdering och redovisning till verkligt värde används förvaltningsfastigheter som ett illustrationsexempel. Detta för att se hur kreditinstituten genomför värderingar och hur de påverkas när börsnoterade bolag redovisar till verkligt värde. Syftet med uppsatsen är att utröna om det föreligger några risker när verkligt värde appliceras på förvaltningsfastigheter.Djupintervjuer med tjänstemän på kreditinstitut har genomförts för att bringa klarhet i hur kreditinstituten ser på och hanterar värdering och redovisning till verkligt värde.Kreditinstituten använder sig av värderingsmodeller för att värdera enligt verkligt värde vilket inte är i enlighet med värderingstrappan.
Ämnestransport med grundvatten i hydrogeologiska typmiljöer
Certain types of waste, e.g. bottom ash originating from municipal solid waste incineration (MSWI bottom ash) can be used as road construction materials. A potential problem is the possibility of substances leaching out of the road and spreading in the surrounding groundwater.The aim of this master?s thesis is to conclude whether hydrogeological type settings can be employed to, based on local conditions, provide an estimate of the probable spreading of these substances in the surrounding groundwater, and whether certain types of soils can be identified as being less suitable for the localization of a MSWI bottom ash road. A hydrogeological type setting is defined as a mappable unit with similar hydrogeological properties.
