Kan detektorer förebygga tågurspårning?

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.

Multiplexad Lusfältsavläsning

I framtiden kommer multiplexad detektion att spela en central roll inom kliniskt bruk. Detta för att utvecklingen av riktad molekylär medicin är på uppgång och kräver studier av interaktioner mellan makromolekyler. Inom forskning används fluorescensmikroskopi för multiplexad detektion men inom kliniskt bruk föredras det att studera preparat med ljusfältsmikroskopi. Dagens problem med ljusfältsmikroskopi ligger i att det är svårt att detektera flera olika markörer samtidigt, multiplexning. Olink har lämnat en förfrågan på en ny testbar metod för multiplexad ljusfältsavläsning (bilaga 3).Bland dagens metoder för multiplexad analys har NuanceTM som baseras på liquid crystal tunable filter (LCTF) och SpectraLamp som baseras på agile spectral light source (ASLS) studerats och utvärderats.

Kan teknikutveckling i form av sociala medier vara produktivt fo?r ledarskap?

The effects of social media usage in a professional context, specifically the effects on social media usage in relation to leadership have been studied in order to determine weather or not usage can be productive for leadership in general. The study concludes that there are several benefits as well as drawbacks to leadership in using social media, but has yet to conclude weather productive or not. This study gives an overview of a relatively unexplored subject.Leadership in terms of leader, communication and group dynamics have been defined and explained in accordance with existing literature. A  brief review of computer and Internet history attempts to explain the formation and evolution of social media. Risks in terms of risks related to leadership and risks related to IT-security are taken into consideration and have been briefly explained.

Att lära med webquest. En fallstudie om studenters erfarenheter av Webquest för barnmorskor vid Karolinska Institutets Universitetsbibliotek.

The main purpose of this Master Thesis is to describe students experiences of learning with Webquest för barnmorskor (Webquest for midwifes) at the University Library of Karolinska Institutet (KI), Stockholm. To investigate the possibilities of acquiring information literacy in higher education with the webquest model a qualitative case study is carried out, based on five interviews with students. The students? perceptions of the webquest course and their ideas on information seeking and information literacy are being analyzed in relation to a framework of learning theory and information literacy expressed by documents and librarians of KI. A descriptive presentation is structured from the main themes that emerged in analysis within the frames of my research questions.

Prevalence of antibodies for Peste des petits des ruminants virus and Brucella and related risk factors in goat herds in urban and peri-urban agriculture in Kampala, Uganda

The world?s population reached more than 6.9 billion people in July 2011. It is expected that the population growth during the next 40 years will take place mostly in low-income countries and the population increase will be 2.3 billion people during 2011-2050. A rapid urbanization is also expected to result in 57.7 per cent of Africa?s population living in urban areas in 2050.

Aktörer och strukturer: en studie av Karlstads stadsbiblioteks framväxt

Solenergisystem i Hammarby Sjöstad

Problems with the current energy system, which partially relies on non-renewable fuels, are increasingly recognized. Emissions of greenhouse gases from fossil fuels may speed up global warming, which in turn leads to a number of negative consequences. Nuclear energy is risky and relies on consumption of a scarce resource. This leads to a demand of renewable energy that is also economically feasible. One possible renewable source of energy is solar energy.

Impulsköpsåtgärder i butik - En fallstudie av 7-Eleven

Should libraries first and foremost be a source of free informationwhere the citizens can find whatever information they want, or dothe librarians have a responsibility for what kind of works theypresent to people on their shelves?

What concepts arespecific for the debate, and what meanings do they get in thesedifferent views?In the concluding chapter I discuss which consequences theseopposing opinions can have for the future selection processes ofthe library..

De omhändertagna barnen - En fallstudie om barns upplevelser av att bli omhändertagna och familjehemsplacerade

Vi har valt att studera omhändertagandet och familjehemsplaceringen, vi vill även ta reda på om placeringen har betydelse i barnens liv. Under 2011 omhändertogs 6300 barn för vård enligt LVU, av dem var 1200 barn nytillkomna. Vi kommer i denna c-uppsats ge de omhändertagna barnen en röst, en röst som förmedlar hur de kände och upplevde de traumatiska upplevelserna när de blev separerade från sina föräldrar. Det övergripande syftet med vår undersökning är att söka kunskap om hur ett barn upplever omhändertagande och familjehemsplaceringen, samt hur det kan påverka barnen i vuxen ålder. Vi har valt att göra en semistrukturerad kvalitativ intervju med personer som har varit familjehemsplacerade under sin barndom.

Civilreligion i George W Bush: s officiella uttalanden : 2001

Uppsatsen behandlar hur USA: s president George W Bush använder civilreligiösa inslag i sin retorik under sitt första år som president. Han startade ämbetsperioden med att använda religiösa anspelningar i sitt installationstal., för att sedan fortsätta i samma anda hela året. Bush är inte den första presidenten att använda sådana retoriska knep. Ända sedan USA: s grundande har presidenterna förstärkt sin talarkonst genom att hänvisa till Gud och att landet är utvalt av Gud - ett nytt Israel. Landets presidenter har alltid varit mer eller mindre övertygade om att Gud står på USA: s sida.
