Experimentellt vidareutvecklad modell för dimensionering av skadebegränsandeåtgärder mot RSV-penetration vid ammunitionsröjning

Vid röjning av RSV-ammunition saknas idag adekvat beslutstöd för att dimensionera skadebegränsande åtgärder mot jetstrålens verkan. I uppsatsen vidareutvecklas en beräkningsmodell som författaren tidigare föreslagit. Syftet är att skapa ett verktyg som kan införas i ammunitionsröjningsverksamheten.Fullskaliga skjutförsök har genomförts för att klarlägga inverkan av förhållanden som är typiska vid ammunitionsröjning; en skyddskonstruktion byggd av sandsäckar och med ett långt detonationsavstånd till röjningsobjektet. Försöksresultatet visar att den grundläggande hydrodynamiska penetrationsteorin inte är användbar för dessa förhållanden. Vidare ger sandsäckskonstruktionen signifikant bättre skydd mot jetstrålen än en homogen grusbädd.Genom störningsanalys har känsligheten hos de enskilda parametrarna i beräkningsmodellen för verksamhetstypiska fel utretts.

Från föhn till feu! : Esrange och den norrländska rymdverksamhetens tillkomsthistoria från sekelskiftet 1900 till 1966

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Extra känslig? : En kvantitativ studie om studenter och vaccination mot svininfluensan

Syftet med den här studien är att undersöka vad som skiljer i personlighet mellan studenter som vaccinerade sig mot svininfluensan och studenter som inte vaccinerade sig. Studien genomfördes genom en kvantitativ enkätundersökning på 194 studenter från ett universitet i Svealand. Deltagarna fick besvara psykometriska personlighetstester som mätte känslighet, ångest, depression, sympati och pålitlighet. Därefter utfördes statistiska test i SPSS för att i huvudsak beräkna medelvärdesskillnader.Resultaten visar att vaccinerade studenter är signifikant känsligare än ovaccinerade studenter. Vaccinerade studenter är också mer ångestfyllda men skillnaderna är inte signifikanta.

Utvärdering av radiologiska kriterier för att bedöma tillståndet ileus på hund :

Dogs presenting with vomiting and abdominal pain, are common patients at the small animal clinic, and the reason for these symptoms can have various aetiologies. One common reason for these symptoms is obstruction of the small intestine caused by a foreign body. Obstruction of the small intestine is best diagnosed by using radiography, contrast-study if needed, and ultrasound. To avoid further examinations, diagnosis from plain radiographs is preferable. One of the signs of illness one can detect from these examinations is a dilation of the small intestine proximal of the obstruction, caused by gas or fluid; ileus.

Solidaritet möter säkerhet - Vad 'immigranterna' får representera i immigrationspolitisk diskurs

This essay concerns the notion of how immigration politics, defined as a political discursive structure that explains and justifies how and why the movement of people into a state's territory is restricted and controlled, has come to present its purpose not as solidarity with the 'immigrants' wanting to enter the state but as a protective measure for the state's citizens. By using discourse theory combined with theories from the International Relations field I attempt to explain why and how such a discourse positions 'immigrants' as a threat to the state.First, I concentrate on why an immigration politics discourse would position 'immigrants' as a threat. I argue that in order for people to construct their identity, the 'outside' what they "are not" has to be repressed. In the same way, the state has to dislocate the "outside" and create threats to uphold its supremacy. These boundaries are set to create a feeling of predictability and security, and ultimately they are a way of making peoples' "world" coherent.

Arbetsmiljöansvar vid uthyrning av personal

As the staffing agency business is rapidly growing and suffering from accidents resulting in higher sick leave than in other businesses, it is of great interest to analyze which responsibilities prevail between the customer companies and the staffing agencies, when it comes to working environment for hired staff.The purpose of this essay is to clarify the distribution of responsibilities between customer companies and staffing agencies, regarding working environment. I would also like to analyze which consequences this distribution of responsibilities may lead to.To be able to answer these questions, I have chosen to use the legal dogmatic method together with the sociology of law method. I have studied legal sources, literature and also interviewed three persons who are active within the staffing agency business; one person from the Swedish Work Environment Authority, one person from the employers? side and one person from the employees? side.The conclusion of my survey is that the SAM-responsibility is divided equally between staffing agencies and customer companies, since the customer company who hires staff is equated with an employer. The employer must also ensure that there is an organized work adaptation and rehabilitation function within the company.

Externa aktörer och transitionsstater En studie om EU som en inflytelserik aktör och transitionsstater på Västra Balkan

In this thesis I discuss about economical and political transition in countries that is consecutively being induced by influential external actors. Looking closer on the role of the EU as a dynamic transitional force, with the intention of examining to what extent the EU can pursuit its interest and modify the economical as well as the political structures of transition countries. With relations to four transition states on the Western Balkans, more precise Bosnia-Herzegovina, Croatia, Serbia-Montenegro and Macedonia (FYROM), I have examined the influential position of the EU. Another feature that is discussed is the approach of the EU and the cause of it in respect to the Western Balkans. Since the end of the crises in Kosovo the EU was given the leading roll in stabilizing and reconstructing the Western Balkans.

Hur kan ungdomar tycka att cannabis är farligt? : En studie om vad som påverkar ungdomars riskperception avseende cannabisbruk

Andelen ungdomar som inte uppfattar några större risker med cannabisbruk har ökat de senaste åren. Ungdomarnas uppfattning av riskerna med cannabisbruk påverkar huruvida de kommer att välja att avstå från eller bruka drogen. Syftet med denna uppsats har varit att se vilka risk- och skyddsfaktorer som påverkar ungdomars riskperception avseende cannabisbruk. Frågeställningarna har varit hur föräldrarna, skolan och vännerna påverkar riskperceptionen. Uppsatsen utgår från en subjektiv syn på riskperception som innebär att inte en faktor ensamt kan förklara om ungdomarna har en låg eller hög riskperception.

Får högpresterande elever den utmaning de har rätt till i skolan? : En empirisk studie baserat på lärares åsikter om arbetet med individualisering med fokus på högpresterande elever

The purpose of this study is to investigate five teachers? opinions on the work with individualization with focus on above-average pupils. I have issued four questions based on the purpose of this study: - How do these teachers define the theoretical concepts of individualization and above-average pupils? - How do the teachers reason about the concept of individualization with focus on the above-average pupils? - How do the teachers reason regarding the work with individualization in the Swedish language? - Do these teachers consider that there are difficulties to individualize the work so that it will challenge above-average pupils?The method used to conduct this study was a semi-structured qualitative interview with five teachers in primary school. The theory and the theoretical concepts this study is based on is: what defines the above- average pupils, the zone of proximal development, the concept of individualization and motivation and the importance of cognitive and non-cognitive abilities.The study shows that the theoretical concept of above-average pupils is hard to define and it shows a difference between how the teachers choose to define it.

Faktorer som påverkar sjuksköterskans användande av omvårdnadsplaner : en litteraturstudie

The purpose is to illustrate the phenomenon of self-harm from a social psychological and sociological perspective. The purpose is furthermore to examine the role social relationships play in the individuals´ self- imagine and what role does identification play for anyone who harm themselves?

Perifer trombolysbehandling på vårdavdelning ur ett sjuksköterskeperspektiv

Children and youth inactivity and sedentary at school is increasing. This means that some of the students have a significant unhealthy lifestyle with physical inactivity, which in turn implies risks of suffering from various diseases, including obesity, type 2 diabetes and cardiovascular disease, all related to a sedentary lifestyle. To prevent illness, it is important that children and young people early get a positive attitude towards physical activity.The purpose of this study was to study the causes of child and adolescent physical inactivity in school, based on teachers 'and parents' perspectives.A qualitative research has been selected. To achieve the study objectives, the author has conducted seven semi-structured interviews, with an appropriate choice of five teachers and two parents with children in school. Data was analyzed with a manifest content analysis.The results show that teachers and parents felt that physical activity is a protective factor for children's health.
