The castration of piglets is performed routinely all around the world. Most castrations are done without anaesthesia and analgesia, despite the fact that this procedure has been proved to induce acute pain and stress for the piglets. The procedure regarding castration of piglets is currently a hot topic of debate and an important political issue. The underlying issue is the boar taint which are highlighted in the heating of the meat after slaughter, which in turn can lead to reduced meat sales as it can be perceived as unpleasant for many consumers. The purpose of this study is to examine alternative drugs which may be selected in order to replace the practice of castration of piglets without anaesthesia, in light of improved animal welfare.

SammanfattningI arbetet beskrivs olika beteenden och fysiologiska förändringar som kan indikera smärta hos hund. Det finns också en kort beskrivning av tre smärtbedömningskalor: Visuell analog skala (VAS) Glasgow Composite Pain Scale Short Form (GCPS) och University of Melbourne Pain Scale (MPS). Dessa skalor har utvecklats som verktyg för att gradera smärta. VAS har tagits fram för humanvården och de andra är utvecklade för bedömning av postoperativ smärta hos hund. Arbetet innehåller också en mindre studie, där skalorna jämförs mot varandra.

The aim of this thesis is to assess the strategic importance of Central Asia as a whole and interests of great powers in the region in particular within the theoretical framework chosen. The work shows Central Asia as an area of the New Great Game, analogue of the original Great Game which was played out between the British Empire and Tsarist Russia in XIX century. The parallels between the original Great Game and the New Great Game are drawn in order to understand the scope and the true intentions of the players of the latter one. Also, the security issues in the contemporary Central Asia are explored and analyzed to provide with the background for future predictions. Furthermore, the indirect purpose of the thesis is to examine whether the international system has changed from that of two centuries ago by comparing the structure of the international systems at the time of two Games.

Avsikten med uppsatsen är att ta reda på om det skapats ett nytt radiolyssnarmönster i och med att Sveriges Radios (SR) erbjuder tjänsten on demandradio, det vill säga möjlighet att lyssna på radioprogram som redan har sänts på vanlig radio eller webbradio. John Fiske Kommunikations teorier har använts samt Walter Benjamin teorier som behandlar förändringar som sker vid reproduktion. Historiska teorier av Marshall McLuhan och Tony Schwartz har även använts.Författarnas metod består av tre delar där en jämförelse genomförts mellan olika sekundära data från SR, Radioundersökningar AB (RUAB), Nordiskt informationscenter för medie- och kommunikationsforskning (Nordicom), British Broadcasting Corporation (BBC) samt Radio Joint Audience Research Limited (RAJAR). Därefter har insamling av kvantitativa data gjorts via enkät som publicerats på SR:s hemsida samt via utskick till en referensgrupp. Författarna har gjort längre telefonintervjuer om cirka 35-45 minuter vilka spelats in och delvis transkriberats för att få in data med mer kvalitativ tyngd.

The European Union provide 27 % of total volume raw milk produced in the world. This number is steadily decreasing due to that the world milk production increase is more rapid than EU production growth. The growing middle-class change the demand for food, a higher standard of living increase the demand of milk products as well as other various animal products. Since 1984 the EU milk quota has limited the supply from EU, but the quota will expire April 1st 2015. The European Milk Board expect that the removal of quotas will make the farm gate price decline.

To produce milk of good standard the feed for the animals kept for milk production is an important part in the work of quality. This makes it important to feed them with good forage, especially when feeding with silage. The process of making silage is very complex and requires a careful handling to be successful. The fundamental idea is to create an anaerobic environment in the herbage to favour the desirable micro-organisms, in this case the lactic acid bacteria. This environment is created by careful handlings were the importance is to pack the crop well and cover it as soon as possible to exclude oxygen.

The purpose of this thesis is to investigate the possibility to make small, cheap and ultra low power sensor platforms, connected in wireless networks for monitoring of home and industrial environments. The concept is based on ideas from our supervisor, Jerry Lindblom. The developed system consists of a generic platform for different sensors, a receiver and software. A GPRS module from RO Rollytech AB and a database from Gema Industri AB have been modified and used to demonstrate an example of a complete system. To the platform, it is possible to connect any resistive sensor and any sensor that can act as a switch.

Concentration of protein in bovine milk is one of the most significant milk quality parameters, to a large extent determining the price for milk to the producer. Mastitis is a common disease among dairy cows, negatively affecting not only milk yield but also milk protein composition. Milk from mastitic cows tends to have lower cheese yield, negatively affected processability properties and sensory quality, due to changed protein quality and composition. Poorer milk protein quality would have an economically negative impact on dairy industry. Only few studies have investigated the short term effects of mastitis on milk protein composition.

Demodikos är en parasitär hudsjukdom som uppstår när ektoparasiten, Demodex spp., förökar sig okontrollerat. Demodexkvalster ingår i hudens normalflora och vad som är etiologin bakom den patologiska förökningen är fortfarande oklart. Eventuella orsaker som diskuteras är underliggande sjukdomar, behandling med immunnedsättande läkemedel, defekter i immunförsvaret och hormonell grund. Demodikos kan förekomma som en lokal och en generaliserad form. Den generella formen av demodikos kräver en långvarig behandling med antiparasitära och antibakteriella läkemedel och flertalet upprepade djupa hudskrap utförs för att följa behandlingseffekten. Djupa hudskrap används i diagnostiken för demodikos och utförs på patienter med klåda och alopeci.
