Ekot från djupaste Afrika : En kritisk diskursanalys av nyhetsprogrammet Ekots gestaltning av konflikten i Goma, Demokratiska Republiken Kongo.
This is a critical discourse analysis of the conformation of the conflict in Goma, Democratic Republic of the Congo, as constructed by Ekot, a news-show on Radio Sweden. The ambition of this bachelor thesis is to examine the production of a Congolese conflict for a Swedish audience and to find out how the construction differences with and without a reporter in the field. To obtain this purpose the narrative is studied as well as the use of voices that define the conflict. The construction of proximity between Swedish audience and the Congolese event and the meaning of sound to stabilize the formation of discourse within foreign news is examined as well. To conform and explain foreign news it must be put in relation to a starting point.
Spelutveckling och lansering av applikation till Android
For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.
Optimering av sotningsfrekvens i biobränsleeldad CFB-panna : panna 5, Mälarenergi AB, Västerås
During the past 30 years the fuels for energy production in heating and power plants
have changed. Fossil fuels have decreased in usage whereas bio fuels in Sweden
have increased with 60% since the 1970's. Different fuels affects combustion and the
release of various substances and particles into the flue gas. This is caused by the
diverse components and chemical structures of fossil fuels and bio fuels. When the
flue gas leave the combustion chamber and enters the path to the chimney particles
in the gas are being transported out of the combustion chamber.
Elanslutning av fartyg i hamn : en studie om förutsättningar och konsekvenser för Köpings och Västerås hamn
The purpose of this thesis is to investigate the possibilities for shore side electricity in the ports of Västerås and Köping. A technical solution to connect the vessels to the local grid is suggested and the investigation is also aiming at an understanding of how the environment is affected by the use of shore side electricity. Furthermore, the costs of shore side electricity are considered.The maximum power demand of a vessel visiting the ports today is relatively small, but the ships visiting the ports in the future might have a larger power demand. The suggested dimension for the system is 5 MW and the result shows that the shore side electricity requires the power distribution to the ports to be expanded. The most useful solution in the ports is to connect the ships with 12 kV from a connection box in a pit at the quay.The investigation of the costs shows that it is cheaper for the ships to use electricity compared to the marine fuel.
Pianisten Hans Roland Orgenius: Först uppåtgående jazzstjärna sedan utkastad från jazzens finrum
Den unge blinde Hans Roland Orgenius hade fått en gedigen musikutbildning på Blindinstitutet Tomteboda när han vid 15 års ålder beslöt att prova på en karriär som jazzpianist. Efter skolan sökte han arbete på Sveriges Radio, där han fick anställning som pianist för att spela i flera radioprogram, ofta tillsammans med sin något äldre kamrat från Tomteboda, Reinhold Svensson. Han började också få spelningar i Stockholmstrakten och blev mycket populär framför allt för sitt sätt att spela boogie-woogie. På somrarna gjorde han turnéer på landsbygden bl a med sångaren Chris Dane. Hans framgångar gav honom skivkontrakt, först med Sonora och sedan Columbia, och han spelade in flera 78-varvsskivor under åren 1952-54.
Havsöringens (Salmo trutta) och laxens (Salmo salar) lekområden och lekvandring i Vindelälven och Piteälven :
The population of seatrout and salmon are threatened by over-fishing in the sea
and loss of spawning and growing habitats caused by logging activities in many swedish
rivers. The knowledge of the spawning migration and the habitat use of the seatrouts
and salmon are limited. This study analyse the upstream spawning migration of Atlantic
salmon and sea-running brown trouts from the lower part of the rivers to their spawning
sites in the rivers Vindelälven and Piteälven. A knowledge about the distribution of
spawning sites in the rivers will help these fish population in future restoration programs.
In the fishladder at Norrfors in the river Umeälven were 29 sea trout and 20
salmon radio tagged and subsequently released and followed during their spawning
migration upstream Vindelälven. They were tracked on their position in the river once a
week.
Nyttan med RFID i IKEAs försörjningskedja - Ett sätt för IKEA att uppnå spårbarhet
Titel - Nyttan med RFID i IKEAs försörjningskedja - Ett sätt för IKEA att uppnå spårbarhet.Författare - Sven MorénJesper SamuelssonHandledare - Mats Johnsson, Universitetslektor vid institutionen för förpackningslogistik, Lunds Tekniska Högskola.Daniel Hellström, Doktorand vid institutionen för förpackningslogistik, Lunds Tekniska Högskola.Allan Dickner, Förpackningschef inom IKEA-koncernen.Nyckelord - Spårbarhet, Märkningssystem, RadioFrekvent IDentifikation, Information.Problembakgrund - Informationsteknologin har medfört stora förändringar för dagens företag. Några av utvecklingarna inom IT är Automatic Identification and Data Collection, vilket har inneburit en avsevärd förbättring med avseende på mängden korrektöverförd data. Radio frequency IDentification (RFID) är en teknologi inom AIDC-området som har börjat användas allt mer, vilket också IKEA uppmärksammat. IKEA är ett multinationellt företag som expanderar kraftigt samtidigt som distributionen blir allt mer komplex, vilket ställer höga krav på ett effektivt och lättöverskådligt flöde. Det förekommer idag många och tidsödande mänskliga fel vid hanteringen av gods vid distributionscentralerna, vilket till stor del beror på olika standards och rutiner för de olika sändningarna.

Neonate mortality in fallow deer (Dama dama) in relation to bed-site selection and habitat use
The level of neonate mortality in a free ranging fallow deer (Dama dama) population at the Koberg estate in south western Sweden was investigated using radio-tracking techniques. During this study a total of 36 fawns (17 ?, 19 ?) were captured and marked with vhf or gps radio collars; 12 fawns in 2008 and 24 fawns in 2009. The neonate mortality calculated by the Kaplan-Meier method was 23.6 % and the mortality caused by predation was low, since only 1 of 8 non-surviving fawns died from predation by red fox (Vulpes vulpes). The spatial behavior of the fallow deer neonates were examined at two different levels i.e.
Kartläggning av kapacitetsutnyttjandet och ställtider på Stålöv AB : Survey of the use of capacity and set up times at Stålöv AB
The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.

Clinical and subclinical mastitis in dairy cattle in Kampala, Uganda
Dairy farming in Uganda provides a source of food, employment and income. Previous studies have revealed high frequencies of bovine mastitis, a costly disease for the dairy farmer. The aims of this study were to investigate the bacteriological panorama in milk from udder quarters with clinical (CM) and subclinical mastitis (SCM) and to determine the antimicrobial susceptibility in staphylococcal isolates. Further, we intended to establish the prevalence of subclinical mastitis and to investigate some environmental factors and animal properties that might influence the frequency of mastitis. For CM, farmers made contact with the members of this study when recognizing an animal with CM.
