Utveckling av kyl- och smörjsystem för ekobilen Agilis HCCI motor

Every year, KTH participates in the Shell Eco Marathon, a competition whose goal is to design a vehicle that can go as far as possible using only the equivalent energy of one liter of petrol fuel. This year, one of KTH?s contributions to this race is the Agilis prototype; a car powered by a uniquely configured HCCI-engine developed at the university. The engine is dependent of several subsystems in order to work properly, among other, systems for cooling and lubrication.Combustion engines are in need of a cooling system that reduces the heat developed during the combustion. In general, two main types of cooling systems are employed; either air cooling, where the outside of the cylinder is exposed to a flow of the surrounding air, ore water cooling, where water flows in tubes around the engine, and the heat are transferred by the water to the surrounding air through a heat exchanger.The purpose of the lubrication system is to prevent the friction that builds up in the interference between moving parts in the engine.

Fodertillgång och stereotypa beteenden under natten hos Asiatisk elefant (Elephas maximus)

Animals in zoos live in more barren environments than their conspecifics in nature. In nature, elephants spend more than 75 % of the day foraging and have been observed lying down two hours during night. Stereotypies are common in many different species in zoos. Stereotypic behaviors may constitute up to 50 % of the daily activity budget of zoo elephants. Modern zoos try to reduce stereotypic behaviors by means of environmental enrichment.

Balkanisering och klassifikation : En komparativ studie av klassifikationen av forna Jugoslavien, beträffande språk, geografi och historia, i DDC och SAB

This master's thesis examines the possibilities of correction and change in a classification scheme, with regard to the changes that occur in the world the classification system intends to describe.Applying a comparative method and classification theory, the classification of the example of the former Yugoslavia (1918-1941, 1945-1991), its republics and successor states, and the languages, formerly known as Serbo-Croatian are examined through a comparison of the main classes and divisions of language, geography, and history, in Dewey Decimal Classification (DDC), and Klassifikationssystem för svenska bibliotek [Classification for Swedish Libraries] (SAB). Eight editions of DDC, from 1876 to 2014, are compared to seven editions of SAB, from 1921 to 2013. The editions have been selected in order to show the changes prior to, and following, the First World War, changes after the Second World War, and changes following the collapse of Yugoslavia in 1991.The examination shows that both systems have updated their editions according to the changes in former Yugoslavia over the years. DDC has well constructed facet schedules, especially Table 2 concerning geography, but fails, in some cases, to construct a logic and hierarchical structure for the republics and languages of Yugoslavia, partly due to the fixed classes and divisions that survive from the very first edition of DDC from 1876, but also as a result of the decimal notation, and its limitations, itself.SAB seeks to construct a hierarchically logic and equal scheme for the languages, areas, and states of the former Yugoslavia. Although the facets for geography and chronology aren't as developed as the ones in DDC, the overall result is that of a logically consistent and hierarchically clear classification, with short notation codes, thanks to the alphabetic mixed notation, which allows more subdivisions than the numerals and the pure notation of DDC.This study is a two years master's thesis in Archive, Library and Museum studies..

Innebörden av begreppet vardagsrehabilitering inom kommunal äldreomsorg

Syftet med denna studie var att beskriva hur innebörden av begreppet vardagsrehabilitering (VR) uppfattas inom kommunal äldreomsorg. Datainsamling utfördes genom enskilda intervjuer med omvårdnadspersonal, arbetsterapeuter, enhetschefer samt beslutande politiker, fem respektive sex i varje grupp. Data analyserades utifrån en kvalitativ innehållsanalys inspirerad av fenomenografi som resulterade i två kategorier: 1) VR innebär kommunikation, samarbete och resurser, samt 2) VR innebär ett synsätt där träning i aktivitet möjliggörs i alla situationer. Resultatet visade att alla respondenter anser att innebörden av begreppet VR är att de äldre inom kommunal äldreomsorg ska få möjlighet att utföra aktiviteter utifrån egen förmåga. Andra särskilt framträdande aspekter gällande VR är att det anses innebära en god kommunikation, vara ett självklart synsätt som inte behöver diskuteras, samt att utbildning är viktigt men inte en förutsättning för att arbeta vardagsrehabiliterande..

Utomhuspedagogik- det outnyttjade rummet

Through a quantitative examination, 26 pedagogies in the pre-school activity answered a few questions in an enquiry about outdoor education. The purpose with this examination was to find out what pedagogies think and apprehend about outdoor education, and also if the "education plan" is in their minds during outdoor activities and if they see them self´s as competent in nature studies. They have also answered questions whether they think that they have good outdoor environment that stimulates children´s development and learning and if there´s any forest that they visit on regular basis.The pedagogies think that during time spent outdoor, it´s the motor skills that are best developed. All of the pedagogies mentioned above think that they need to get more educated in nature studies and also that pedagogies attitude towards time spent outdoors affect the children. They do not think about the goals and intentions of the "educations plan" all the time.

Patent och företags storlek - finns det en tröskel till inträde?

Several studies have investigated the relationship between different measures of innovative activity, such as patent statistics and R&D expenditures and some have looked deeper into the differences between large and small firms regarding number of patents issued per employee or per R&D dollar. In this paper, the objective is to find out if there are any indications of a barrier to entry (due to economical factors, lack of knowledge etc) for small firms to get into the field of patent handling. The approach is to first set up a hypothesis based on some simple assumptions about how firms would make decisions about whether to apply for a patent or not and thereafter use econometric methods in an empirical investigation. The data used for this study are figures on number of employees, number of patents granted and R&D expenditures for the Swedish firms in the pulp and paper industry. The main conclusion is that, based on the analysis of the data from this rather limited group of firms, no such barrier can be seen..

The purpose of this study is to analyse the attitude of four teachers to leadership in the classroom. The main research questions asked were:What are the teachers` views on leadership in the classroom?What does good versus  bad leadership mean to the teachers? What factors influence the teachers' leadership in the classroom, according to themselves?The method used is the qualitative method and interviews, which is my empirical material, I relate to different theories and previous research of leadership.The curriculum for the compulsory school system, the pre-school class and the leisure-time centre, Lpo 94, says a lot about how both the school and the teacher must pursue a democratic activity; the teacher must have a democratic leadership in the classroom (Lpo 94, s. 5). At school, the pupils should be met with respect, they should feel safe and be motivated to learn.

Scoutförskola : En förskola med scoutprofil

Due to the interest of starting a preschool with a scout profile in my circle of acquaintances I chose to write my report about how the scout method would work in a preschool. I did this by comparing the origin of scouting and preschool. I based my report on the following questions:Are there any similarities or differences with curriculum, education act and the scout method that can make it easier/harder to work with the scout method in the preschool?There are many theorists that have had influence on the preschool. Give some examples of their theories that could affect the scout preschool?What is the difference between a teacher and a scout leader?What would a preschool look like if you included the scout method in the daily activity?With the help of my literature studies I compared the scout method against the laws and rules to make sure that the scout method doesn?t contradict them.

Demokrati och diskurs. En normativ analys av diskursiv påverkan på de demokratiska värdena öppenhet, ansvarsutkrävande och inflytande

The idea that I put forward in this thesis concerns the democratic system and the threat from discoursive impact on its core values. I focus my normative analysis on three of these democratic values: transparency, accountability and influence ? and what democratic problems the discoursive impact causes in conflict with them. I have used a critical discourse theory to define discourse and discoursive impact, by focusing on the process of discourse, rather than its nature. I deal with the political structure where I claim that the essential relation between citizen and politician is disrupted, due to lack of information and the imminent problems of the existing network society.

Ambulanspersonalens upplevelse av regelbunden strukturerad fysisk aktivitet

Ambulanspersonal (ambulanssjuksköterskor, specialistsjuksköterskor och ambulanssjukvårdare) förväntas klara av både fysiska och psykiska påfrestningar och samtidigt utföra en patientsäker vård. Framförallt de fysiska påfrestningarna kan skapa muskuloskeletala besvär hos ambulanspersonalen. Muskuloskeletala besvär kan leda till arbetsrelaterade förslitningsskador i nacke, skuldror, ländrygg och knän. Syftet med studien var att beskriva ambulanspersonalens upplevelse av regelbunden strukturerad fysisk aktivitet. Studien utfördes med kvalitativ design och en induktiv ansats där sex manliga deltagare intervjuades.
