Oljefilmens tjocklek mellan kolvring och cylinderlopp
Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremostwithin applications in the industry. These motors have several sliding contacts, one of these, isthe contact between piston ring and cylinder bore. The radial piston hydraulic motors advantageis to produce high torque in very low rotation velocity, this result in that the maximum slidingvelocity between piston ring and cylinder bore, during the whole stroke, is very low. Theconsequence of this low sliding velocity is that the contact between piston ring and cylinderbore, during the whole stroke, is bound to the boundary lubrication regime. This result in, thatthe piston ring is exposed to wear, thus affect the service life of the complete hydraulic motor.To minimize wear of piston ring, it is essential to determine the oil film thickness between thepiston ring and cylinder bore.

Genotypisk bestämning av ESBL-producerande E. coli isolerade i Kronobergs län 2009
Vanlig tarmbakterie som Escherichia coli (E. coli) kan bland annat orsaka infektioner i bukhålan och urinvägsinfektioner. Infektioner orsakade av bakterien har ofta behandlats med betalaktamantibiotika, som penicilliner och cefalosporiner, vilket har resulterat i selektion av antibiotikaresistenta bakterier. Extended-Spectrum Beta-Lactamases (ESBL) är enzymer som hydrolyserar 3:e generationens cefalosporiner som cefotaxim, ceftazidim och ceftriaxon, men kan även bryta ner penicilliner, monobaktamer och övriga cefalosporiner. ESBL förekommer främst hos E.
Tycho Hedéns Väg : trafikrum blir stadsrum
Tycho Hedéns Väg in Uppsala has evolved from being a through fare passage and highwayto the oversized road frame running through the city it is today. At the present time, dueto the relocation of the E4 highway east of Uppsala, Tycho Hedéns road creates a barrierbetween the north eastern area of Uppsala and the remaining parts of the city centre. Theroad is designed to endure heavy traffic and high speed limits, generating a surrounding urbanarea were inhabitants are complied to follow the standards set for a high traffic-accessibleenvironment. Furthermore, the heavy traffic has led to the turning of both urban roadsidesaway from the actual road. The aim of this project and proposal is to show the possibilities ofhow the innate features of Tycho Hedéns road can be used more advantageously to mend thecity area of Uppsala.
Feministiskt initiativ - en idéanalys
Feminist initiative ? an idea analysis.On the fourth of April in the year 2005 Feministic initiative (Fi) was created, it was an main response to the slow changes in the Swedish society, which claimed to establish an equal society. Equality has become one of the major indicators of a contemporary democratic society. The Swedish government has long proclaimed to reach this goal, but even though Sweden currently lies in the front among the democratic societies, while you consider equality issues, especially between the sexes, there is still a lot that need to be done in the Swedish society. Feministic initiative began as an organization and established a political party and participated in the election during the year 2006, but failed to reach a place in the parliament.

The purpose of this study was to examine the political party ?Feministiskt initiativ? (Fi) and their communication during the election campaign 2006. We wanted to find out what the intention was and how the communication was received by the public. We also looked for signs of congruence between those two sides.Fi is the first political party with a feministic ideology to candidate for the parliament in Sweden. The party is rather new and their political standpoints and internal affairs have often been subject of for debate in the media.We wanted to investigate people?s individual opinions of the matter, and therefore we chose to personally interview a number of people.
Infectious bronchitis in Brazil : a minor field study in Bastos municipality, Sao Paulo
Infectious Bronchitis (IB) is a highly contagious viral respiratory and productiondepressant disease distributed world wide. The disease is caused by the InfectiousBronchitis Virus (IBV), a positive RNA strand Avian Coronavirus within thegenus Gammacoronavirus. Due to a combination of high mutation rate and atendency of recombination a constant emergence of new genotypes and serotypesis seen. In Brazil, a country with an extensive poultry production and majorproblems with disease control, the diversity of circulating strains are wide andoutbreaks of clinical disease despite intensive use of vaccines are common. Theaim of this study was to investigate the presence of IBV and to identify genotypesof isolated IBVs in a limited number of layer flocks in Bastos, São Paulo, as partof the screening for circulating genotypes in the country.
Begomovirus susceptibility in wild Nicaraguan tomato populations
Tomato production is a common and important agricultural activity in Nicaragua. During the last decades tomato producers have suffered great yield losses due to begomoviruses (family Geminiviridae). The genome of begomoviruses generally consists of two circular ssDNA components, DNA-A and DNA-B. Tomato yellow leaf curl virus (TYLCV) is an example of a begomovirus with only one component. An approach to manage the virus epidemics has been to breed a cultivar with begomovirus resistance genes, which have been transferred from wild tomato.
Skogsbrandens påverkan på död ved :
Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris).
Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.

Har en gemensam valuta resulterat i en minskad prisspridning? : En jämförande studie på priskonvergens inom euroländer i förhållande till övriga EU länder
In 1993 the internal market within the European Union was formed and ensured free movement of goods, services, capital and people. This led to the removal of trade barriers between members of the European Union. When opening up for competition, price differences between countries decreased and more jobs were created. A single currency was introduced by eleven countries in 1999 with the goal of reducing transaction costs, eliminating exchange rate risk and to further simplify trade. In 2001 Greece joined the collaboration and introduced the euro.
Debatten om Biblioteksdatoriseringen : tendenser i Biblioteksbladet, Bis och DIK-forum 1970-1999
The purpose of this thesis was to trace and discuss tendencies in the debate of the computerization of the libraries, in Swedish library press during the period of 1970-1999. The set-out was the issue of how the library journals, as representatives and mouthpieces of a by tradition humanistic profession, coped with a revolutionary innovation related to a field (data technology) which they hadn't any knowledge or even interest in. The examination included three Swedish library journals: Biblioteksbladet with connection to Sweden?s most established library organization (SAB); Bis which is founded upon a socialistic base and; DIK-forum rooted in the union. The analysis of the debate was partly based on three different sets of values related to data and systems development.
Beredskapsstress?
Stress är en växande folksjukdom i Sverige och en grupp som kan vara särskilt utsatta för kumulativ stress är soldater som ligger i beredskap. Vi har från våra förfäder ärvt en förmåga att vid fara reagera med en stressreaktion som en förberedelse för kamp eller flykt, också med en reaktion som gör att vi kan bli handlingsförlamade. Om dessa reaktioner upprepas gång på gång utan att kroppen får utlopp för den höjda energinivån ökar slitaget på kroppen. Stresshormoner samlas i kroppen och byggs på och kan under en längre tidsperiod leda till kumulativ stress. Om detta fortsätter kan det leda till ett utmattningssyndrom.Syftet med uppsatsen är att kartlägga hur soldater som ligger i beredskap upplever sin allmänna hälsa och den stress som de dagligen utsätts för.
Sjuksköterskans uppföljning av läkemedel i kommunens äldreomsorg : en empirisk studie med kvantitativ ansats
Bakgrund: Det är en vanlig arbetsuppgift för sjuksköterskan att följa upp effekt och eventuella biverkningar av läkemedelsbehandling för återkoppling till ordinerande läkare. I och med att sjuksköterskan i den kommunala äldrevården har en konsultativ roll, är informationen mellan henne och vårdpersonalen, som är nära patienten dygnet om, mycket viktig. Denna del av läkemedelskedjan är av central betydelse för att minska onödigt lidande för den äldre patienten i form av läkemedelsrelaterade problem. Syfte: Att kartlägga hur sjuksköterskan i kommunens äldreomsorg följer upp läkemedelsordinationer avseende effekt och biverkningar, särskilt i de fall när patienten själv inte har förmåga att uttrycka sitt mående i ord. Metod: En empirisk studie med kvantitativ ansats.
