Förutsättningar för småskalig solelproduktion i Australien

The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.

Informationsarkitektur ur ett användbarhetsperspektiv : En fallstudie hos Länstrafiken

Förmedling av information inom en organisation är en viktig del för att det dagliga arbetet ska fungera. Rätt person ska få rätt information på rätt sätt. Vår undersökning syftar till att visa hur en informationsarkitektur som utformas utifrån användarnas behov kan förbättra en verksamhets informationsförmedling. Genom en fallstudie på Länstrafiken i Örebro undersöktes vad för information dess användare vill ha och hur de vill ha den. Frågorna som undersökningen ämnar besvara är: -          På vilket sätt kan ett användbarhetsperspektiv leda till en förbättrad informationsarkitektur?-          Hur optimeras informationsförmedlingen med en användarcentrerad informationsarkitektur? En användarcentrerad informationsarkitektur utformas utifrån användarnas behov.

Hur ska elförsörningen tryggas vid tredimensionell fastighetsbildning? : Hur behandlar Lantmäteriet och elnätsföretagen frågan?

SammanfattningTredimensionella fastigheter är, i större utsträckning än traditionella fastigheter, beroende av att samverka med omkringliggande fastigheter för att bli lämpliga för sitt ändamål. Av den anledningen finns särskilda villkor för att sådan fastighetsbildning ska få ske. Bland annat måste fastigheten tillförsäkras vissa nödvändiga rättigheter redan vid bildandet. Det här arbetet fokuserar på en specifik typ av nödvändig rättighet som de allra flesta tredimensionella fastigheter har behov av, nämligen elektriska starkströmsledningar. Hur rätten till dem ska tryggas preciseras inte i lagtext, utan är upp till Lantmäteriet att besluta om i de enskilda fallen.

Tvärfunktionell produktutveckling : - En utredning på Scania om samverkan mellan konstruktörer och produktsamordnare

The role distribution between designers and product coordinators and the system support between these roles are adapted according to the method of working that product models primarily are created for production and after sales market. At the same time models are also created to support a cross-functional way of working. This means that product structures exists on paper and as CAD-models before they are created in Scanias PDM-system environment which leads to unnecessary work and to information not being shared as early as it should be possible.A theoretical study has been performed with the purpose of understanding the problems and to create a foundation for improvement suggestions. Representatives from both roles have been interviewed together with other individuals with insight in the collaboration. A minor study concerning the roles of interests? collaboration at Volvo CC was also performed to be able to relate the study to another company.

Stora Enso : Vägen till ett lyckat hållbarhetsarbete

 There is an ongoing reorganization within media industries today as they adapt to new and changing demands - the environment is changing fast and the organizations with it. The development of new technology is contributing to new forms of media distribution in the present media industry. The structure of media organizations is getting flatter and the co-workers are getting a new and bigger role. All this is bringing new challenges for the leaders of the organization. Caught in the middle of these new structures is the middle manager who now is facing different demands from all sides.

Unga musikkonsumenter : En studie av vad som påverkar unga konsumenters val av populärmusik

Den uppsats som i följande beskrivs har syftat till att ur ett konsumentperspektiv undersöka och förstå vad som gör att unga konsumenter väljer att lyssna på den populärmusik de lyssnar på. Detta för att förstå hur marknadsförare ska marknadsföra artister i den förändrade musikindustrin. För att uppnå detta syfte har tre stycken fokusgrupper genomförts med ungdomar i åldrarna 16-18 år från Stockholm. De frågor vi formulerat till fokusgrupperna baserades på hur unga konsumerar musik, hur de skaffar information om musik, vilken roll spelar andra ungdomars musikval, vad som skulle få dem att betala för musik, hur de definierar sin personlighet, samt hur de visar grupptillhörighet. Svaren tolkades utifrån teorier inom konsumentbeteende och marknadskommunikation.

Prevalence of toxin-producing strains and antimicrobial resistance in isolates of Staphylococcus hyicus from pigs with exudative epidermitis and from healthy pigs

Virulent strains of Staphylococcus hyicus produce exfoliative toxins and cause a potentially fatal skin disease in piglets known as exudative epidermitis. Vaccines and antimicrobials are used to control the disease. Antimicrobial resistance and the prevalence of several different toxin genes and toxigenic strains make it problematic. The aim of this literature study was to identify potential differences between countries and between healthy and diseased pigs regarding antimicrobial resistance and toxin-producing strains. Great differences could influence vaccine production, treatment strategies and surveillance programs.

Impact by bomas on the distribution of spotted hyena (Crocuta crocuta) in the Mara Region, Kenya

The aim of this study is to find out if, and in what way the Maasai pastoralists affect the spotted hyena (Crocuta crocuta) through Bomas (Maasai settlement) and keeping of livestock. The study was carried out in the Maasai Mara National Reserve and the adjoining group ranch, Koyake GR, in South-western Kenya.Data was assembled through transect driving, with instantaneous scan sample during two seasons, December 2003 and May-June 2004. Study area contained 12 bomas with three different type of transects each: T1 (0.5 km from boma), T2 (3 km from boma) and T3 (5.5 km from boma), to create a gradual decline in human and livestock impact. Results show that there are differences in the hyena's utilisation of transect type during the day and during the night. The spotted hyena tend to avoid transects close to the boma during the day time, but go there during the night time.

Human attitudes toward large carnivores bear, wolf, lynx and wolverine : a case study of Västerbotten County

Management of large carnivores involves more than just the management of animals, people also have a large influence. The Swedish parliament decided in 2009 that the county boards should use co-management to a greater extent in management. This shows how important human dimensions are.We know from previous research that the majority of people in Västerbotten are positive toward large carnivores and the management done by the state, however there is a negative minority which should not be neglected. This paper contributes with an examination of attitudes toward large carnivores, wolf, bear, lynx and wolverine, in Västerbotten County. The data for this study were derived from a survey that was sent out to 150 randomly selected persons in every commune in following counties: Norrbotten, Västerbotten, Jämtland, Västernorrland, Dalarna, Gävleborg and Stockholm.

Hur påverkas insatser för elever i behov av särskilt stöd av beslut på olika nivåer? : En studie av insatser på tre skolor i samma kommun

The intention with this study is to investigate how schools are affected by state and municipal documents when they organize the education for children with special needs. The study is based on following questions.How do decisions on state and municipal level of politics affect the decisions that the principals make concerning organization, and do the school leaders think that the decisions are made on the right level of liability?What is the relationship between economic decisions and pedagogical decisions?What decides whether the schools have children with special needs integrated in their ordinary classes, or if they receive segregated remedial courses, and what are the views on an equivalent education?The study is conducted through interviews with principals of three schools, one politician on municipal level and one special education teacher. The interviews are linked to an historic background as well as current studies and discourses. The study shows that there are contradictions between state, municipality and school goals.

Varför betala?: En uppsats om varför vissa betalar för musik och andra inte

The end of the 20th century brought a dramatic change to the music industry. The then predominant models for music consumption and sales were forever altered when the possibility to distribute music over the internet emerged. It has now become evident that it is virtually impossible to stop the distribution of digital music files. Music has turned into a non-excludable and non-rival product, which in economic terms is described as a public good. Public goods theory serves as a starting point for this study, which explores some of the factors that might explain why some consumers pay for music, while others choose to download music illegally.

Clear-cut and substrate characteristics important for the occurrence of the beetle Upis ceramboides

Disturbances, such as fire and wind, are important for saproxylic beetles (= beetles depending on decaying wood) to gain substrate in boreal forests. Clear-cutting is an example of a man-made disturbance. Measures such as prescribed burning have been made to resemble natural disturbances. The aim of this study was to see which clear-cut characteristics are important for the occurrence of the saproxylic beetle Upis ceramboides. This is a species favored by open habitats and is said to respond positively to forest fires. The distribution area in Sweden for this species has decreased during the last two centuries and I wanted to see if there were differences between clear-cuts in Hälsingland, where it is very rare and decreasing, and Norrbotten where this study was conducted.

Identifiering av konfliktbestånd med hjälp av laserskanning

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.
