Provmetod för olje- och partikelöverdrag från kompressor till tryckluftssystem
Compressed air is an energy source that is widely used in today's trucks and buses.Compressor located next to the engine supplies the pneumatic system with the compressed air and is lubricated with the engine oil. Some of the oil follows the air flow in both liquid and solid phase. The solid phase, namely the carbon particles are created due to the high temperature in the compression chamber.Oil- and particles carryover softens and destroys the rubber material in the air valves and disturbs the mechanical function of various components in the pneumatic system. In order to reduce oil- and particles carryover is an Air Processing System (APS) set downstream the compressor.No method for establishment of oil- and particles carryover from the compressor exists at the moment. Therefore the filtration efficiency of APS is currently unknown.
Thymidinkinas 1 som tumörmarkör vid juvertumörer hos tik :
Determination of serum thymidine kinase 1 (TK-1) activity is used as a tumour
marker in both human and veterinary medicine. TK-1 is an intracellular enzyme
involved in a salvage pathway of DNA synthesis. The expression of TK-1 is cell
cycle dependent and the activity increases markedly after the G1 to S transition in
the cell cycle and then declines rapidly in G2. The pronounced proliferative
activity in tumour cells result in a higher TK-1 enzyme activity within the cell.
The fact that the increased TK-1 activity can be measured in serum makes TK-1 a
useful marker in diagnostics of neoplastic diseases and it provides information
regarding prognosis and treatment effectiveness. In human medicine a radioactive
based test is used to determine the TK-1 serum activity.
Att mäta eller inte mäta? : En kvalitativ undersökning om prestationsmätningar på en av Blekingesjukhusets kliniker
Blekinge Hospital suffers from a budget shortage of 100 million SEK, while the government now requires that hospitals will no longer be running a deficit. Blekinge Hospital will then use their limited resources to survive in the future and the activity must be enhanced in order to keep costs low without having to lay off personnel. The idea is that the organisation should be more efficient with a more efficient resource usage. Performance measurement systems are important tools for achieving the policies set out within an organization, measuring and evaluating performance is a way to see where improvements in efficiency may be necessary in the business. Balanced Scorecard (BSC) is one of several measuring systems, where the focus is on measuring non-financial performances.
Förebyggande trafiksäkerhetsarbete inom föreningslivet : En intervjustudie bland idrottsföreningar
Nollvisionens mål är att ingen ska omkomma eller skadas allvarligt i trafiken. Varje år dör ungefär sex personer och många flera skadas i samband med idrottsresor. Att arbeta förebyggande med trafiksäkerhet hos idrottsföreningar kan vara ett sätt att bidra till en ökad trafiksäkerhet i Sverige. Syftet i denna studie var att undersöka vad idrottsföreningar uttryckte kring förebyggande trafiksäkerhetsarbete. Vilka uppfattningar som framfördes gällande trafiksäkerhetspolicy och vilka förutsättningar som fanns, samt vad som kunde förstärka trafiksäkerhetsarbetet.
"Att hjälpa är att lära" : En kvalitativ studie om betydelsen av socialt stöd för ensamkommande flyktingungdomar
Every year a great amount of unaccompanied children flee their homelands without their parents or guardians. This means a journey filled with danger and difficulties. The difficulties don?t only exist during the road ahead but also when the children arrive to the new country. Even if Sweden?s work in receiving refugees is one of the best in the world, it still exist problems.
Konflikter på gång och cykelbana. : Ett skadepreventivt perspektiv.
Att vistas på gång- och cykelbanor kan vara en situation som upplevs som otrygg av de oskyddade trafikanterna som delar på detta utrymme. Samexistens och hänsyn till medtrafikanter är av vikt för att minska konflikter och skador som uppstår i denna miljö.En anledning till konflikter mellan fotgängare och cyklister är den höga hastigheten som cyklister kan färdas i. Denna hastighet skapar otrygghet bland fotgängare samt hos de cyklister som färdas i ett långsammare tempo. Otryggheten, beteende hos de båda trafikantgrupperna samt hastigheten leder i vissa fall till konflikter med kollisioner och personskador som följd. Att separera gång- och cykeltrafiken minskar till viss del konflikterna mellan dessa två grupper, men konflikten mellan cyklister som färdas fort och de cyklister som färdas långsamt kvarstår samt att otryggheten till viss del kvarstår hos fotgängarna, speciellt i de fall separeringen enbart skett med färgmarkering.
Intelligenta Switchar
This master thesis has been carried out on behalf of Stoneridge Electronics AB and is an investigation ofhow intelligent switches can replace the traditionally used direct controlled switches. The concept ofintelligent switches is that the switches contain electronic identification components which, by connectingthem to a network, give the same function independent of the location of the switch. This infers anincreased flexibility and configurability which can be a great advantage in development, production andcustomization in the commercial vehicle industry. Especially in the current situation when commercialvehicle manufacturers provides more and more functions and dashboard configurations.LIN (Local Interconnect Network) is a network protocol introduced in 1999. It is a simpler and lower costcomplement to CAN (Controller Area Network) and is adapted for applications where the demands forbandwidth are lower, for example reading sensors and switchers.
Tolvmansgården : -en skärgårdsträdgårds historia och framtid
Summary
The place I have been working with is a garden, belonging to a family estate, called Tolvmansgården. It is located on an island northeast of Norrtälje in Roslagen. The frontage is red with white corners like so many other houses in the neighbourhood, but ours is one of the oldest houses on the island. Today the house and garden is own by my mother, Pia Johansson.
Since I?ve started my education in garden design my interest for our country garden has increased.
Utvärdering av en behandlingsperiod i varmt klimat för personer med pelvospondylit
Purpose: To evaluate how a treatment period on four weeks in a warm climate influences physical function, condition and the patient's experience of the climate effect of patients with ankylosing spondylitis. Method: 10 persons with a diagnosis of ankylosing spondylitis went through four weeks of treatment on Centro Forestal Sueco, Marbella. The treatment consisted of both physical and theoretic lessons given of a rehabilitation team. All patients were examinated measured for physical function and condition before treatment, after two weeks and at the end of the treatment. To measure physical function, Timed-Stands Test, Timed Get Up and Go, The Bath Ankylosing Spondylitis Metrology Index, Index of muscle function and functionestimitation of shoulder/arm were used.
Tillsats av biokol till en svensk sandjord : effekter på lustgasavgång, kväveretention och andel vattenfyllda porer
In a column experiment the effect of three different biochars on nitrous gas emissions, nitrogenretention and water filled pore space (WFPS) were studied in a Swedish sandy soil, classified as aCryopsamment. Ammonium retention was positively correlated, while KCl-extractable ammoniumwas negatively correlated, with the specific area of the biochars. The question was raised whether thenegative correlation between extractable ammonium and biochar specific area reflects the amount ofammonium present in the soil or its extractability from the biochar, and whether methods forextracting soil mineral nitrogen, like KCl-extractions, have to be modified for application on biocharamended soils. There was a tendency of increased nitrate retention and KCl-extractable nitrate withbiochar and KCl-extractable nitrate was positively correlated with the specific area of the biochar. pHwas higher for all biochars compared with control, although the differences were not significant, andWFPS was lowered by biochar addition, significantly in one case.
Torkning av vallfrö :
In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the
fields, this is primarily used as feed for livestock. To get a good seed, you need to
handle the crop carefully from planting to delivery. The part that I have been
interested in, is how to dry the harvested seed with out destroying the growth in the
small seed. This is very easily done if you aren?t careful during the drying period.
En jämförelse av krypteringsalgoritmer
Today the Internet is used more and more as a transportation for information.
Much of the information is confidential and should not be read by those not
privileged. To protect the information from unauthorized access cryptography
can be applied. The cryptography algorithms in use today all have their pros
and cons. They are therefore suited for different applications.
Gångvägsljus :
Discussing light and lighting in the night-time environment of Tensta, a Stockholm suburb built between 1962 and 1970, this thesis suggests that lighting should be designed for the outdoor environment as a whole. The feeling of safety and human perception are important components in this thesis.
Starting with some comments on visual perception and how we adapt our sight to an interval of the visual input we get, makes it possible to understand that more light sometimes hides, rather than reveals, things. Amongst the dispersed houses, in the green parks of Tensta, this turns the pedestrian roads, lit by pole-top-mounted fixtures, into light tunnels in a dark surrounding.
Talking about the feeling of safety I am inspired by, amongst others K. Lynch, B. Hjort and J.
Anläggningsmodellering i AutoCAD Civil 3D
SammanfattningExamensarbetets syfte är att ge en övergripande bild om vad BIM egentligen är och hur arbetsmetoden ska kunna påverka byggprocessen positivt. Rapporten fokuserar på anläggningsbranschen och då främst från en projektörs perspektiv. Ett projekteringsexempel visar även på hur en anläggningsmodell kan skapas med hjälp av en programvara som stödjer arbetsflöden i BIM.BIM kan utläsas Building Information Model och avser då den eller de modeller som utgör en digital objektbaserad representation av en byggnad eller en anläggning. BIM kan även utläsas Building Information Modeling och avser då ett arbetssätt, d.v.s. processen att skapa och använda en eller flera byggnadsinformationsmodeller i bygg- eller anläggningsprocessen.Det finns många fördelar med att använda BIM, inte bara i husbyggnad utan även i anläggningsbranschen.
Undersökning av elkvalitet i distributionsnät med omfattande vindkraftselproduktion
The goal for this master thesis project has been to investigate the power quality in adistribution grid, which has a high fraction of dispersed power production due towindmills. The study has been done on a grid in Laholm South of Halmstad, whereapproximately 45 windmills are connected to the distribution grid owned by SHKEnergi. The investigation has been focused on to two radialy fed 20 kV lines, wheretwelve windmills are connected.Voltage variations have been studied by creating a model of the grid in the simulationprogram SIMPOW. The largest deviation that has been found in any point of the gridis ±1.9 % of the nominal voltage. This deviation is a result of varying powergeneration from the windmills and the voltage regulation at the connection point ofthe line.
