Konceptstudie av drivmodul till bandskotare med hybriddrift

BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

Styrning och nödbroms av ModuLith

The purpose of this project is to get a fully functional, automatic steering system and a variable breaking system with an emergency breaking function to an off road vehicle. This off road vehicle is supposed to work as an aid in military situations. A team of two, Sebastian Attervall and Nichlas Gustafsson, got an order from Jonas Nyårds and the PreeRunners Project to construct a steering system that could manoeuvre an off road vehicle without any human involvement. To make this possible the vehicle would be guided by onboard sensors, cameras and computers. The team where also assigned to construct an automatic breaking system, there also no human would be involved.

Sjuksköterskors kompetens inom traumavård på en akutmottagning : en pilotstudie

Bakgrund: Sjuksköterskor som arbetar på akutmottagningar förväntas ha en hög kompetens inom traumavård. Med hög kompetens menas att de utför ett komplext och avancerat arbete och har ett stort ansvar i det initiala omhändertagandet av traumapatienter. Syfte: Syftet med studien var att beskriva sjuksköterskors självskattade kompetens inom traumavård på en akutmottagning Metod: Studien är empirisk suveystudie med kvantitativ data som samlades in genom att en enkät delades ut till sjuksköterskor på en akutmottagning. Sjuksköterskorna fick skatta sin kompetens inom traumavård utifrån svensk sjuksköterskeförenings sex kärnkompetenser samt efter deras formella och kliniska kompetens. Resultat: Huvudresultatet är att nästan alla (94%) av sjuksköterskorna vårdar traumapatienter oavsett erfarenhet och formell utbildning.

Rapid emergency triage and treatment system (RETTS): Test av interbedömarreliabilitet -En pilotstudie

Inledning: Syftet med föreliggande studie var att testa interbedömarreliabiliteten för det i Sverige vanligaste triageinstrumentet Rapid Emergency Triage and Treatment System (RETTS). Instrumentet består av 42 kontaktorsaker (ESS) som kombinerat med mätta vitalparametrar, t.ex. blodtryck och puls, ger en triagefärg. För att kunna bedriva evidensbaserad omvårdnad krävs att instrument, skalor och metoder är valida och reliabla. Statens beredning för medicinsk utvärdering anser att RETTS saknar både validitets- och reliabilitetsdata.Metod: Två ESS från instrumentet valdes.

Inredningskoncept för vägambulans : Ett examensarbete vid Industridesignprogrammet 2011

The subject of this bachelors degree project is an interior layout for road ambulances.Landstinget Västernorrland (LVN) wanted a layout concept that would be used to com- municate their design intentions to the ambulance producers during their purchase process.Designing ambulance interiors is an extremely complex process since there so many fac- tors to take into consideration. It ?s not just about taking the equipment and place it where there is space left in the cabin. You have to start with the user in focus and the tasks that are to be performed in the ambulance environment.It ishard to find design solutions that will fit 100% of the ambulance personnel?s working routines for 100% of the tasks.

Anafylaxi ur ett sjuksköterskeperspektiv Kunskap, erfarenhet och riktlinjer påverkar identifiering och behandling

Anafylaxi är en akut, oförutsedd, allergisk reaktion som kan uppkomma när som helst. Alla sjuksköterskor skall ha kunskap om anafylaxi, samt beredskap att ta hand om denna reaktion på ett korrekt sätt. I bakgrunden beskrivs den immunologiska mekanismen vid anafylaxi och allergi, symtom och behandling, samt det omvårdnadsvetenskapliga perspektivet. Syftet med denna litteraturöversikt var att identifiera och beskriva bidragande orsaker som ligger bakom osäkerheten kring anafylaxi och därmed ge en ökad kunskap om anafylaxi i sjuksköterskans professionella omhändertagande. Metoden som vi har använt oss av har varit litteraturstudie och sökning har skett via databaserna Pubmed, Cinahl och Scopus.

Hjärt- och lungräddning eller inte - en etisk konflikt inom prehospital sjulvård

SammanfattningSyftet med studien var att beskriva och sammanställa befintlig forskning om de etiska konflikterna, som ambulanspersonal ställs inför i samband med HLR och att inventera om prehospitala HLR riktlinjer tar hänsyn till etiska aspekter på HLR. En litteraturstudie genomfördes där tretton vetenskapliga artiklar analyserades. Resultatet visade att etiska konflikter uppstod när det gällde ambulanspersonalens beslut om att påbörja HLR eller inte, på patienter som av litteraturen beskrevs som terminalt sjuka eller äldre terminalt sjuka patienter. Ibland kränkte ambulanspersonalen patienternas autonomi genom att påbörja HLR mot patienternas och de anhörigas vilja, trots att det existerade en Ej HLR önskan från patienterna och deras anhöriga. Den huvudsakliga orsaken till att sådana situationer uppstod var oklarheter i lagstiftningen omkring prehospitala HLR riktlinjer i USA och Kanada.

Konstruktion och design av hjul

The task given to us was to develop an industrial wheel with new thinking in terms of fresh design and construction, with the ability to brake. While the produced wheels of today only own the property of total braking, a wish was made to integrate the ability of directional locking.The time spent working with the project has been filled with multiple sketches of ideas and function analysis.Choices of material and ways of construction have been verified by calculations, tests and prototype building. The goal of this thesis has been to develop a unique caster with well thought-out design that would be adaptable to different areas of applications.The result was a hubless wheel with the ability of directional locking before total braking.A prototype of the wheel has been made to show the design and functions..

Kartläggning av kvinnors amningsupplevelser på BB : -en enkätundersökning

Previous research and patient complaints to the Swedish Patient Support Committee shows that there is a lack of substance in the patient-nurse relationship. This may suggest that it can be difficult for health care to live up to health-care law which requires it to be of good quality, based on dignity and respect and designed so that the patient is an active participant and can make their own decisions when it comes to their health care. For a better understanding of what a dignified patient-nurse relationship is, this study aims to clarify what the patient values as good patient-nurse relationship and describe how they have experienced the patient-nurse relationship during their stay at an emergency care department. The study is a descriptive cross-sectional study with a quantitative approach, where the population consisted of patients who were cared for at an emergency care department in the County of Västmanland, Sweden during 2007. The sample consisted of 93 patients which were asked to answer a questionnaire.

Sjuksköterskan och omvårdnaden i det akuta omhändertagandet : En kvalitativ studie

Bakgrund. På akutmottagningen är flödet av patienter stort och möten mellan sjuksköterskor och patienter är korta och tidspressade. Det primära för patienter på en akutmottagning är att sjuksköterskan vet vad som ska göras. Omvårdnad kan delas upp i två kategorier: instrumentell omvårdnad och emotionell omvårdnad. För att agera med omvårdnad, måste sjuksköterskan dels ha ett omhändertagande med teknisk kompetens och samtidigt stödja patientens emotionella behov.

Träbroar för järnvägstrafik

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.
