Syftet med denna studie är att undersöka prevalensen av obstruktiva problem från de övre luftvägarna hos svenska travhästar vid maximal ansträngning. Undersökningen genomförs med hjälp av en ny typ av utrustning där man kan endoskopera hästar under maximalt arbete på en travbana.Tidigare har undersökning med endoskopi på rullmatta varit enda sättet att undersöka hästar under ansträngning, men tack vare ny teknik är det nu möjligt att göra det vid maximalt arbete, under för hästen normala tävlingsförhållanden. I studien ingår 110 varmblodiga travhästar som sökt för missljud från de övre luftvägarna, nedsatt prestation eller båda delarna. Hästarna undersöktes med endoskopi, både i vila och under maximalt arbete. Resultaten i vila och vid arbete har sedan jämförts.Diagnostiska bilder har erhållits från samtliga hästar och därmed kan prevalensen beräknas i den undersökta populationen.

School and education are topics that are frequent in Swedish media. The intention of this essay has therefore been to investigate the image of teachers and their profession in Swedish daily press. The overall aim has been to analyze how teachers are portrayed in the debate that followed the TV-show Klass 9A, and by that find how the debate defines the concept of a good teacher. The representation that was found was then compared to earlier studies. The series was shown on Swedish television between January and March 2011.26 articles were chosen and the ambition was to have various perspectives represented, such as different voices and also papers from different areas of the country.

In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated.  This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.

The purpose of our study is to examine whether social welfare secretaries experience obstacles in work to do their tasks in a way that they, from their own values, thinks is right. And if so, what are the reactions and what strategies do they use to manage this. The study is based on a qualitative method. The data consist of interviews, with five social welfare secretaries, which all work in southern Sweden. The social welfare secretaries both work at a children- and youth department and at a social allowance department.

Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

Höghastighetsfilmning är en teknik som ofta används inom rörelseforskning på häst, särskilt för att registrera ledrörelse. Reflektoriska hudmarkörer sätts på anatomiska landmärken, vilka sedan filmas med höghastighetskameror. En felkälla med dessa mätningar är att huden förskjuts jämfört med underliggande skelett. Detta fenomen beskrevs första gången i början av 1900-talet och har sedan dess studerats relativt omfattande framför allt för hästens extremiteter men även för ryggen. Däremot har hudförskjutningen på halsen inte studerats tidigare och det var syftet med det här arbetet. Halskotorna på fem hästar markerades med röntgentäta hudmarkörer för att sedan röntgas i olika positioner, normal position, placerad ?i form? med välvd nacke och nosen i lodrätt plan samt med ?nos mot karpus?.

With growing economies and better living standards in many parts of the world today, there is a need of expanding the capacity of generating electricity. The alternatives for renewable energy technologies are not fully developed and have still some problems to conquer.The company Minesto has developed a technology that is called Deep Green. It is designed to gain electricity from tidal currents. Deep Green works in a similar way as a kite that is attached to the seafloor with a moving wire. It contains of a wing that moves due to the water current.

Husums plant has a selection of different pulp pumps at bleaching plant 4 and 5. The displacement- (HC-pump, Sund Defibrator PTD-60) and centrifugalpumps (MC-pump, MCA 42-200, MCP 30/20) are of interest in this report. The centrifugal pumps are controlled by throttle valves, which result in an energy loss. Chemical mixers are used to mix ClO2 into the pulp before proceeding into a holding tower where the bleaching process occurs.The energy demand of the different positions has been measured or calculated to be used in comparisons against new equipment. Quotations were requested and delivered from Valmet and Sulzer.

For the Swedish artist Björn Lövin, the personal was a problem. In his first exhibition in Moderna Museet, Lövin observed through the fictitious character Mr. P (for »Personality«) the ruptures in the Swedish welfare state. The exhibition Konsument i oändligheten och Herr P:s penningar (Consumer in Infinity and Mr. P?s Money) (1971) was composed of two environments, through which a veridical working class apartment and a high street with life-sized mannequins and furniture characteristic of its time, visualized the societal discrepancies in the welfare state as well as the art world of the early 1970s.

The Swedish Transport Administration manage nearly 4,000 railway bridges in different condition and age around the country. These bridges is in constant need of maintenance and requires continuous inspections. This thesis is designed as a damage investigation on a single-track railway bridge south of Solvarbo in Säter municipality. The railway bridge is in operation and serves over 10,000 trains a year, everything from speed trains to freight trains. The bridge is built as a beam bridge, simply supported over a road.

The competitive nature of the automotive industry has always implied a necessity to improve product development concerning time-to-market, cost and product quality. As capacity of computer-aided engineering (CAE) tools has evolved, so has the strive for simulation-driven design. Virtual durability testing using full vehicle models is one of many challenges posed in front of vehicle manufacturers when computer simulations are given a key role in product development.This thesis has been initiated as a preliminary step towards implementing dynamic virtual durability testing in the development of buses and coaches at Scania. The objective has been to assess the predictability of a full vehicle coach model and to what level of precision structural loads can be predicted. Previously performed proving ground testing of a Scania Touring coach has been the basis for the modelling and simulations in this thesis.A virtual model of the Scania Touring coach has been created in multi-body simulation software package MSC.Adams.
