Höft- och knäprotesoperationer är idag en vanlig operation vid artros i höft- och knäled. Trotsminutiösa infektionsförebyggande förberedelser inför operationen drabbas ändå en delpatienter av postoperativa infektioner. Vid ortopedisk proteskirurgi är postoperativainfektioner ett direkt hot mot den nya inopererade leden och kan leda till långabehandlingstider som påverkar patientens livskvalitet under lång tid.Syftet med studien var att utforska patienters möjlighet till delaktighet i tidig upptäckt avpostoperativ infektion utifrån given information vid operation för höft- eller knäprotes.Semi-strukturerade intervjuer genomfördes med tio patienter med diagnostiserad postoperativinfektion efter höft- eller knäprotesoperation. Transkriberade intervjuer analyserades medinnehållsanalys. Journaler granskades för att beskriva patientens tidigare sjukdomar.Resultatet visade att första tecknen på infektion kan beskrivas med temat: Vad är normalt ochvad är inte normalt.

Bakgrund: Flera studier beskriver vikten av att minimera dörröppningsfrekvensen på operationssalarna. Högre frekvens av dörröppningar leder till försämrad ventilation på operationssalen, vilket i sin tur kan leda till vårdrelaterade infektioner.Syfte: Syftet med denna studie var att på en operationsavdelning observera frekvensen av dörröppningar under pågående operation, varför och av vem de öppnades.Metod: Metoden var en kvantitativ deskriptiv observationsstudie med tvärsnittsdesign. Personalen på en operationsavdelning i Mellansverige observerades under pågående operationer. Observationerna utfördes sex vardagar i januari 2013 och valdes från operationsprogrammet.Resultat och slutsats: 22 observationstillfällen observerades, 11 från vardera konventionell respektive infektionskänslig kirurgi. Studien visade att dörröppningsfrekvensen var högre vid konventionell kirurgi jämfört med infektionskänslig.

The aim of this report is to examine the possibilities to use network theories to perform vulnerability analysis on complex networks. The scoop of this work is also to improve the possibilities to chart, analyze and present the vulnerability in a power grid. In this report it has been, using power outage statistics, possible to verify, that network theories can be used to evaluate the vulnerability of an infrastructure network. However further studies to establish values on how vulnerable a network is are needed..

In today?s technological society, there are increasingly less physical demands on the locomotor system. However, despite that notion strength and function in the hand?s complex biomechanical system are in fact both needed to cope with daily life. The grip function is a main function in the hand and is used in many examples of scientific research, for instance when assessing physical health and predicting the probabilities of premature mortality.

ABSTRACTIntroduction: Preoperative hand disinfection aims to prevent surgical site infections. After the preparing hand wash, drying is performed using an aseptic technique. It?s important to dry hands thoroughly in order to achieve the full effect of the alcohol based hand disinfection. Due to the lack of a evidence-based guideline on this procedure, the hand drying techniques differ among operating theatre nurses, depending on which technique seen as the most appropriate.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

Bakgrund: Dagkirurgi, att opereras och gå hem samma dag, är en vårdform som har ökat markant i Sverige senaste åren. Tidigare studier har visat att många patienter som genomgår dagkirurgi upplever oro inför operation, vilket orsakar lidande för individen men också ökat behov av sömnmedel och ökad risk för postoperativ smärta och oro. För att kunna genomföra omvårdnadsåtgärder för att minska oro måste den först identifieras, vilket framförallt är anestesisjuksköterskans uppgift i mötet med patienten. Syfte: Att undersöka patienters skattning av sin oro vid ankomst till operationsavdelningen vid dagkirurgi samt hur väl anestesisjuksköterskans skattning av patientens oro överensstämmer med patientens egen skattning. Metod: En kvantitativ enkätstudie som genomfördes på två operationsavdelningar i Uppsala län under en veckas tid, totalt inkluderades 88 patienter och 60 anestesisjuksköterskebedömningar.

The aim of this study was to describe how body language of humans affects the domestic dog (Canis familiaris) and how it can be implanted in the stressed situation that occur at an animal hospital. The subject is brought to notice because the author has experienced that dogs can get more stressed when a stressed and nervous owner is attending. Humans affect each other through posture, facial expression, voice and movement, and are often driven by their emotions, which can differentiate the verbal communication from the non-verbal communication. This occurs both consciously and unconsciously. Every human uses body language but not everyone knows how it is used or how to understand it.

In industry applications, such as power supply plants, the issue of interaction between fluid and structure is always presented. More precisely, the fluid flow affects the structure by applying force(s) on it and vice versa. As a result, the structure can move (vibrate) or deform. A good understanding of this problem can help to design the system in term of safety, stability and efficiency.This project aims to optimize and test the Unicorn FSI solver from the FEniCS project [1] to simulate the interaction of fluid and structure in an experiment, which was carried out at Vattenfall Research and Development. The target is to improve the Unicorn FSI solver to cope with a real industrial problem.

Background: Prostate cancer is the fourth most common cancer disease in the world and affects mainly older men. While having prostate cancer the treatment can be both medical and surgical and both these treatments can give side effects like erectile dysfunction, lost libido and hot flushes. Sexuality among elderly is often associated with taboo, but sexuality exists among elderly and is important for their wellbeing and quality of life. It is common that nurses don?t address and discuss questions concerning sexuality with patients, even though they know that sexuality often is affected while having a disease or experiencing illness.

Flertalet studier har påvisat ett samband mellan koncentrationen av partiklar ? 10µm i luftföroreningar och cardiovaskulär- och pulmonell morbiditet och mortalitet. Vid resektion, koagulering/bränning med diatermipenna under operationer alstras rök. Denna rök innehåller bland annat mutagena och carcinogena partiklar i inhalerbar storlek (partiklar ? 10µm).Ett första syfte med denna studie var att kvantifiera den mängd ultra-fina partiklar (UFP) och partiklar ? 10µm som operationspersonal exponeras för i operationsrummet, vid användande av diatermi med mobilt rökutsug.

Syftet med vår studie är undersöka och få en allsidig belysning kring ett lågtröskelboende, som vi har valt att namnge som DD. Vi vill undersöka kring hur personalen går till väga för att uppnå funktionen och målet med verksamheten. Detta är en studie som ha en kvalitativ metod som ansats, därav baseras på sex stycken halvstrukturerade intervjuer. Vi kommer i studien ge en kort redogörelse kring verksamheten. DD är en verksamhet som erbjuder plats för hemlösa personer som har en omfattande problematik bakom sig, där många har blivit utslussade från härbärge till härbärge, boende till boende.

Animal welfare during transport has for a long time been a problem around the world. Many animals are transported in stressful environments for slaughter. Even during Roman and Antiquity times wild animals were transported from Africa to the amusement parks in Rome. The aim of our work was to compare how well Sweden and Denmark are performing their inspections of transports of cattle and pigs for slaughter. Today, overloaded transports and poor treatment is not uncommon in Europe and every year 22 million animals are transported between countries.

To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.
