Flygplansavisningens miljöpåverkan vid svenska flygplatser

The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.

Den nya Arenan : Dansband eller Rock 'n Roll för Kalmar som destination?

Syftet med den här uppsatsen är att studera om den nya Arenan kan komma att vara en bidragande faktor till säsongsförlängning i Kalmar. Eftersom den nya Arenan inte ännu är färdigbyggd, vill vi undersöka beslutsfattares syn på projektet samt hur ett sådant projekt kan komma att påverka Kalmar som destination.För att kunna studera verkligheten, utan att styras av redan befintliga teorier, valde vi i vår studie att använda oss av en induktiv ansats. Den större delen av vår datainsamling grundas på kvalitativa intervjuer, vilka vi kompletterade med diverse rapporter och skrivelser på hemsidor.Vår slutsats i den här uppsatsen är att den nya Arenan kan bidra till säsongsförlängning om verksamheten maxas. För att detta ska vara möjligt bör samtliga beslutsfattare börja spela i samma lag, klara och tydliga mål med projektet måste sättas upp och fokus bör läggas på hur ett projekt av den här storleken kan gynna hela Kalmar som destination, inte enbart en av de inblandade aktörerna..

Beroende- och missbruksmönster gällander alkohol och droger hos män och kvinnor : En litteraturstudie

Bakgrund: En ökad medveten närvaro kring måltiden och ätandet genom mindful eating har i ny forskning visat sig vara en effektiv metod för att minska en rad olika sjukdomar och hälsorelaterade problem samt bidra till gynnsamma hälsoeffekter. Trots detta finns få studier genomförda i en svensk kontext.Syfte: Undersöka och beskriva graden av mindful eating hos en grupp individer på sociala medier i förhållande till Body Mass Index och demografiska variabler.Metod: Deskriptiv tvärsnittsstudie med en kvantitativ ansats. Ett tidigare utvecklat instrument, Mindful Eating Questionnaire (MEQ), översattes och distribuerades som en webbaserad enkätundersökning. Respondenterna rekryterades under en veckas tid genom ett snöbollsurval på det sociala nätverket Facebook. Inklusionskriterierna var att deltagarna skulle behärska det svenska språket, vara mellan 20-65 år och användare av Facebook.

Motviktsslungans dynamik : En analys av medeltida konstruktionsråd för mekaniskt artilleri

 AbstractThis Master?s thesis analyses the dynamics of the medieval counterweight lever engine, ortrebuchet, a type of mechanical artillery. The purpose is to study the differences between different types of these machines, and see if computer simulations can be used to validate preserved advice on construction. Simulations include machines with a fixed counterweight, a hinged counterweight and a combination of both counterweights.Due to the almost complete lack of archaeological finds and insufficient historical source material there are still, after more than a century of research, many unanswered questions concerning the design and performance of these machines.The present study is based on an analysis by Jahsman (2004). A more detailed mathematical model employing Coulomb-friction is used.

Gravitationslinser

Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..

Turbiditet som ersättningsmått för totalfosforhalt i kustmynnande vattendrag i Östergötland

Eutrophication is a major problem in the Baltic Sea, as a result of increased loading of nitrogen and phosphorus. In the coastal parts of Östergötland the soil largely consists of clay and contains high levels of phosphorus bound to clay particles. Erosion of the soil in agricultural areas makes the water turbid and transports phosphorus to the Baltic Sea. The aim of this project was to examine the relationship between phosphorus and turbidity in the coastal streams of Östergötland. The aim was also to evaluate the possibility to use turbidity as a surrogate measure for phosphorus.

Sociala medier i Kina : En studie om användningen av sociala medier i en diktatur

The current research examined whether motives, traditional mass media consumption and individual differences (social activity and political interest) predicted the use of social media among a group of university students in China. In coherence with Uses and Gratifications assumptions the study found that the factors differentially predicted the extent of media use. Information seeking, social interaction and affinity were the main reasons for using social media. There was a negative correlation between television viewing and use of social media, in addition to a negative correlation between information seeking and use of the media. Results further suggest that social media are used to enhance social capital, since student?s being socially active offline, tend to use the media to a greater extent than those less active..

Bland kockrockar och rock-kockar  - En retorisk analys av svenska matlagningsprogram

Aim: The purpose of this paper is to see if there has been a change over time in the performance and in the spoken word of the Swedish cooking programs. By testing the theory of intimization on the cooking programs I get the opportunity to see if the border between the private and the public have become clearer or more difficult to notice, and if the new language, the informal language as intimization entails, has been used in Swedish cooking programs since the 70s until today, or if there´s ever been a formal language in Swedish programs? Method/Material: I'm using a rhetorical approach that includes a three-step analysis. Analysing the context, means to persuade and performance. The empirical material I intend to analyze is Swedish cooking programs from the 70s until today, 2010.

Dagdrömmar

Dagdrömmar är en tapetkollektion bestående av tre fondtapeter som kombinerar det moderna, massproducerade digitaltrycket med traditionell, unik broderiteknik. Genom att tillföra handbroderi och dess struktur och textila känsla till ett digitaltryckt tapetmaterial skapas en kollektion som befinner sig i gränslandet mellan design och konst, lyx och budget samt dröm och verklighet.Daydreams is a wallpaper collection consisting of three images that combines the modern, mass-produced digital printing techniques with traditional, unique needlework. By applying embroidery ? with its structure and fabric texture ? to a digitally printed wallpaper material, a collection is created that lingers on the borders between art and design, luxury and modesty as well as dream and reality..

Kommunal avfallsplanering i storstaden San Salvador, El Salvador

This paper deals with the use of Internet at Swedish public libraries. The author asks whether public libraries should or should not limit access to information available on the Internet. Starting from the American discussion, concerning Internet at public libraries, the author shows the Swedish attitudes. The paper demonstrates that many Swedish public libraries have adopted rules forbidding retrieval of certain kinds of information, such as hard-core pornography and racist propaganda. The persons in charge of such actions claim that public libraries should provide high-quality educational literature and should not spread mass-produced, provocative information.

Fosforläckage från växtodling - orsaker och ågärder :

Phosphorus is essential to all plants and is taken up from the soil as the ion H2PO4 - (and to some extent HPO42-). Plant availability depends on, among other factors, the soil pH. In order to provide for plant available phosphorus, it is applied as mineral fertilizers and farmyard manure. However, that causes phosphorus leaching from arable land to surrounding surface waters and lakes and contributes to the eutrofication. There are three types of soils in Sweden that are at higher risk of contributing to phosphorus leakage.
