The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

Saab Bofors Dynamics har som huvudsaklig verksamhet att utveckla missiler. Ofta krävs det att någon form av navigationsfunktion byggs in, och eftersom det inte är lätt att testa nya lösningar och algoritmer direkt på missilerna har man tagit fram två autonoma testplattformar, Freke och Gorm, i form av självgående bilar som kan ta sig fram inomhus i t.ex. en korridor.För navigation utomhus lämpar sig GPS väl i många situationer, men i autonoma sammanhang är det inte tillräckligt. GPS är inte alltid tillgänglig på grund av att man inte alltid har fri sikt till minst fyra satelliter och i militära sammanhang är den också lätt att störa ut. Därför förlitar man sig hellre på noggranna tröghetsnavigeringssystem (TNS) som kan ge data i 100-tals Hz, och kompletterar med GPS för att korrigera för avvikelser.

Today we have more game species than ever before in our landscape, both regarding number of species and number of individuals. The increasing number of wild species is an increase in game recourse for the countryside. The increase of game species, however, has negative effects on forests and agriculture land. The negative effects for forestry are damages on economic important trees, due to losses in production and quality. However there are ways to decrease the damage on valuable and important trees.

Unhealthiness is not just a damaged back or asbestos. The fact that mental ill-health seems to increase in our society is well known. Statistics from Arbetsmiljöverket proves a fourfold increase of work-related disorders since 1997. These are primarily caused by organizational and social factors, 60% are considered caused by stress and a heavy workload. Sick leave due work related fatigue and depressions are scarily common today.

SummaryHerbal remedies have been used for many years to alleviate various symptoms. They were used in ritual acts to reassure the Gods and as medication. Plants as rhubarb and ginseng were used in China long time ago. The Egyptians had knowledge of herbal medicine such as aloe, myrrh and henbane, 1550 BC. The father of medicine Hippocrates used a large number of herbal medicines, and had many theories on the subject.Different parts of the plant can be used to extract the active ingredients.

Problem Faith in the power of advertising has varied largely through the ages, and since we know that advertising is paid for, it therefore has less weight than the usual news. Publicity through promotional activities is in turn difficult to control. The question which of these two ways to communicate with the market that is the most effective, is equally entitled to ask, as difficult to answer. Purpose/Aim This paper is designed as a pilot study with two different objectives that go hand in hand. The first overall aim is to investigate how advertising and PR / publicity can be measured with the same tools while designing this metric.

The purpose of this study was to look for tendencies that social media can contribute to exposing users to a stronger perception of opinion polarization, and further to see if the daily presence of social networking sites can put normative pressure on the users. The study was made using a survey with participants from Umea? University during the time frame of november-december 2014. The theoretical framework behind the study was mainly drawn from The Spiral Of Silence by Elisabeth Noelle-Neumann and was further supplemented with more current research, studying the effects from The Spiral Of Silence in the modern and more fragmented media landscape that exists now then when her theory was written. Further theoretical tools for analysis of the results came from Michel Foucault and his discussions in Discipline and punish, specifically his views on how surveillance can be discontinous in practice, but still permanent in it?s effects.The results of this study indicates that social media users tend to isolate themselves from uncomfortable opinions, and do not follow or read opinions they do not already agree with.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

ABSTRACTBackground Calprotectin is a protein found in the cytoplasm of neutrophile granulocytes. In the course of inflammatory bowel disease (IBD), calprotectin is released during chronic inflammation in the gut. Activation of neutrophils during the inflammation is followed by activation and secretion of pro-inflammatory molecules such as calprotectin. Calprotectin is stable in stool up to 7 days and can therefore be used as a non-invasive marker for diagnosis, treatment and measurement of the disease activity in patients with IBD. The most common method for analysis of calprotectin concentration is ELISA.

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

I Sverige drabbas varje år ungefär 12 000 personer av afasi och av dessa är cirka 35 % i yrkesverksam ålder. Afasi är en samlingsbeteckning för skador som drabbar språkförmågan. Dessa skador kan medföra olika konsekvenser för individen och de kan påverka kommunikationen i livet och vardagens aktiviteter. I arbetsterapeutens roll, ingår det att hjälpa den som har drabbats av afasi att hitta strategier och möjligheter för att klara sig i vardagen, därför behövs kunskap om behandlingsmetoder för personer med afasi. Generellt syftar behandling vid afasi till att förbättra språkförmågan.

Trycksår är en vårdrelaterad skada vars prevalens är utbredd på sjukhus i Sverige. Denna hudskada uppkommer när ett ihållande tryck orsakar att underliggande vävnad skadas. Riktlinjer finns utformade för hur preventionsarbetet med trycksår ska utföras, och syftar till att minska prevalensen av trycksår. Syftet med studien var att undersöka sjuksköterskors syn på trycksårsprevention relaterat till patienter som ligger inlagda på somatisk vårdavdelning. De undersökningsmetoder som användes var av både kvalitativ och kvantitativ ansats. Materialet samlades in via enkäter och det slutliga informantantalet uppgick till 29 informanter.

The focus of the paper is to study how a store manager can influence their employees to perform better on the job, in terms of service to customers and increased sales. The aim is to analyze the different tools store managers use to motivate their employees with the goal of improving service to the customer and to increase sales.

Många byggnader är idag fuktskadade. Fuktskador uppstår på så väl nya som gamla byggnader. Idag provtrycker man hus för att få ett värde på dess täthet, men många hus som klarar täthetskraven drabbas ändå av fuktskador. Detta beror på att otätheterna är lokala på en eller flera delar av klimatskalet bortsett från otätheter vid anslutningar.  En studie har gjorts på två väggtyper; en standardvägg och en passivhusvägg.
