Bakgrund: Perifer venkateter (PVK) är en allmän och rutinmässig åtgärd inom hälso- och sjukvården för att kunna lindra, bota och behandla genom att tillföra infusioner, läkemedel eller för att hålla en fri venväg. PVK består av ett främmande material som i kontakt med blod kan leda till att komplikationer som tromboflebiter bildas. Vid minsta tecken på rodnad, ömhet, svullnad, tromboflebit eller extravasation ska PVK avlägsnas. Syfte: Studiens syfte var att beskriva de senaste forskningsrönen kring sjuksköterskans omvårdnadsåtgärder för att undvika PVK-relaterade komplikationer. Metod: Studien är en litteraturstudie där resultatet baserats på kvantitativa och kvalitativa artiklar.

At the Department of Technology and Built environment at the University of Gävle there was an interest to study GNU Radio, which is an "open source radio project. The project is based on that most of the radio signal processing is made in an ordinary PC. The idea behind this degree project was that in a laptop there are several radio transmitters/receivers that takes space, generates heat and transmit in varied frequency band etcetera. All these radio transmitters/receivers could be replaced with a Software Defined Radio system. It means that one common, general radio hardware is used to different communications such as: WLAN, Bluetooth, GPRS, 3G etcetera. The waveform is generated in the software, which makes the system very flexible.

This Master thesis discusses the development of a virtual human soft tissue object for use in exercise applications of various medical procedures.The soft tissue object to be developed shall look like, feel like and behave as living human tissue. It shall give the user a realistic feeling of weight, softness and roughness, and shall behave in a correct way for exercise purposes. The soft tissue model is to be used in a three dimensional stereo graphic environment with haptic feedback. A prototype for practicing the procedure of inserting a catheter is built. The prototype is used to evaluate the potential of the virtual environment for medical exercise applications, and to assess the realism and usability of the soft tissue object.

The purpose of this study is to investigate and describe what factors are most important to students when choosing training center, and how these factors affect the choice of each training center. We investigated this by performing a qualitative research and a quantitative survey of students at Karlstad University that trains at Friskis & Svettis and Sats in Karlstad. The results show that there are a number of important factors in the total customer experience that affects a student's choice of training center and that they also differ between a premium center and basic center. Our conclusion is that when a total customer experience concept consists of a core, core experience and peripheral experiences well linked into each other competitive advantages is created, resulting in more satisfied and loyal customers. .

Bensår är en kronisk sjukdom och ger ofta underbensödem vilket gör att såren blir svårläkta. Den viktigaste behandlingsmetoden för att undvika ödem är kompressionsbandage. Många av de patienter som drabbas av bensår tycker att sårläkningsprocessen är svår att acceptera och de har därför problem med att fullfölja kompressionsbehandlingen. Syftet med studien var att undersöka vilka faktorer som hade betydelse för patientens följsamhet vid kompressionsbehandling av bensår. Arbetet har gjorts som en litteraturstudie av vetenskapliga artiklar.

Al- Rudainy, F & Bernados-Kjaerran, A. Kvinnliga patienters upplevelser av att erhålla urinrörskateter. En empirisk studie om kvinnliga patienters upplevelser av att erhålla urinrörskateter. Examensarbete i omvårdnad 15 högskolepoäng. Malmö högskola: Hälsa och samhälle, Utbildningsområde omvårdnad, 2011. Syftet med denna studie är att beskriva kvinnliga patienters upplevelse av att erhålla urinrörskateter (KAD).

In this essay I discuss and analyse if we can witness any signs on regional dimension due to regional representation from our elected representatives in the five constituencies Malmö, Blekinge, Norrbotten, Uppsala and Stockholm. Two seperate terms of office between 1991-94 and 1998-2002 has been compared. In political science there has been much debate about the relationship between voters and their elected. By measuring each and everyone elected representatives in the work of produce introduced bills towards their own constitiency during both terms I have tried to see if there is an occurence of a regional dimension.The theory that´s been applied is based on geographical representation where one might aspect that central metropolitan areas and peripheral regions is somewhat over-represented in legislatures. By using a method of comparison between the five chosen constituencies and theirs elected representatives I have come the the conclusion that there is a weak tendency that this might be the case seen to a regional dimension perspective..

PICC-line är en central venkateter som läggs in via en perifer kanyl i överarmen med hjälp utav ultraljud. Patienter som behöver intravenös behandling i mer än fem dagar är i behov av en central venkateter för att säkerställa tillförseln av dessa läkemedel. Inläggning är kostnads effektiv, den kräver ett minimum av resurser och görs utav picclinesjuksköterskor. Denna kvalitativa studie med semistruk-turerade frågor syftade till att ta del av patientens upplevelse av att få en PICC-line kateter inlagd. Kände patienten sig lugn under ingreppet, var han eller hon väl informerad och upplevde personen någon smärta? Tio intervjuer genomfördes och resultatet visade att informanterna kände sig lugna och att smärtan var låg.

Detta examensarbete har genomförts på uppdrag av Totalförsvarets Forskningsinstitut. Examensarbetet är ett av fyra delprojekt i projektet Telekommunikationer för strid i urban miljö. Projektet syftar till att ge förslag på metoder och utrustning som kan underlätta för soldaten på taktiskt nivå, i Försvarsmaktens insatsförband, genom att förbättra informationsinhämtning och -överföring.Syftet med examensarbetet är att i en praktisk demonstration visa nyttan med MIMOsystem antingen genom ökad kapacitet eller genom ökad tillgänglighet.Examensarbetet är uppdelat i tre olika delar: förstudie, utveckling av teknikdemonstrator i hårdvara samt demonstrationer och presentationer. Demonstratorn är byggd medGNU Radio mjukvara, som körs på två Linux-maskiner, med Universal Software Radio Peripheral som RF hårdvara. För att visa fördelarna med MIMO har spatiell diversitet implementerats i en mottagare.Implementationen visar att bitfelshalten reduceras till en tredjedel jämfört med en SISOmottagare..

The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.

The aim of this study was to investigate the relationship between sleep, photoperiod, milk yield and hormones connected to milk formation. Variations of prolactin (PRL) and Insulin-Like growth factor-1 (IGF-1) in plasma were measured during two different light programs. The light programs consisted of either 24 hours of light (L24:D0) or four hours of light and 20 hours of darkness (L4:D20). Five cows of the Swedish Red breed were used in a cross-over experiment and each light program consisted of five days. Milk yield was measured at every milking and milk samples were analyzed with regard to fat, lactose and protein.

Blood sampling is one of the most important diagnostic tools in veterinary medicine, and this is also true for avian medicine. A properly collected and handled venous sample can be used for serology, biochemistry and electrolyte analysis, as well as for blood smears, packed cell volume and cell differentiation. Caring for sick birds is a challenge for all veterinary staff. Many birds are easily stressed individuals, and to a very ill bird a big increase in stress level can even be fatal. Avian patients who are presented in a veterinary clinic are often in a poor condition, and blood sampling is an invasive procedure that can cause stress to the patient.

The purpose of this thesis is to create opportunities for an efficient interchange of information between humans and technology, especially for the skilled user, and put the designprincipal for informative structures and features into practice. Informative structures and features in a large number of information items helps the peripheral visual system to automatically capture knowledge through logical patterns.A field experiment was done to evaluate if informative structures and features, implicate efficient human information-processing, even in a small study. The results was ambiguous because the quantitative part of the investigation didn?t show any significant differences, whereas the qualitative showed that people prefer a dynamic document with a high degree of informative structures and features over a dynamic document with a low degree of informative structures and features. Even if this study was inconsistent, probably because to few subjects where used, the implication of the research that?s behind it is solid.

Propofol is an intravenously administered, hypnotic and short- acting pharmaceutical. One common sideeffect (>1:10) and therefore a disadvantage with propofol is the local pain that arise when the initial injection is given. Why the pain arise is not clearly understood. A majority of different pharmacological treatments, different doses and combinations, alternative administrations methods and physical interventions have been tried to reduce the pain when injection of propofol is given. One important task for the nurse is to relieve pain for patients.

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .
