Att förebygga anestesiinducerad hypotermi ? en studie inom gynekologisk laparoskopisk kirurgi
IntroduktionDet är väl känt att varje patient som opereras riskerar att drabbas av hypotermi peroperativtoch postoperativt. Hypotermin medför stora risker för patienten med bland annat ökadinfektionsbenägenhet, ökad blödning och försämrad metabolism. Vidare bidrar det till ökad frekvens av shivering med alla dess komplikationer. Att kunna förebygga hypotermi både vid öppen och laparaskopisk kirurgi är en viktig uppgift för anestesisjuksköterskan.SyfteSyftet med denna studie var att undersöka om anestesisjuksköterskan med hjälp av ettvarmluftstäcke i form av ett tubtäcke och en luftvärmeblåsare peroperativt kan förhindrauppkomsten av peroperativ hypotermi vid gynekologisk laparaskopisk kirurgi samt om detta minskar patientens lidande i form av mindre shivering och frysning postoperativt.MetodI denna studie randomiserades patienterna till att antingen få ett varmluftstäcke peroperativteller sedvanlig behandling. Patienternas kroppstemperatur registrerades kontinuerligtperoperativt och postoperativt.
Mozzarella : En djupdykning i ostmassan
Worldwide consumption of cheese has increased over the years. The average Swede consumes somewhere around 20 kilograms of cheese per year, which is an increase of a 100 % over the past 50 years. One of the most popular kinds of cheese during the past decades is mozzarella, due to its? use as pizza cheese. Flavor and consistency differ between the traditional kind, made out of buffalo?s milk, and the industrially made kind, made out of cow?s milk.
?Jag jobbar som polis men jag brukar inte säga att jag är en polis? : En kvalitativ studie om polisyrkets påverkan på den enskilde individen med fokus på roller samt emotioner
The purpose of this study is to gain a better understanding about the police profession's impact on the singular individual, with a focus on roles, regions and emotions. The main question is to understand if and then so, how individuals outside of work will be affected of the profession and professional events. In order to answer this question I carried out six semi-structured in-depth interviews with police officers who worked at the main office in a police region in a midsize city in Sweden. To ensure reliability and allow readers to conduct their own assessments the quotations in this study are anonymous. The analysis of the collected material is based on selected parts of Goffman's theories about dramaturgical perspective as well as selected emotion theories.
Pilotmodeller till flygmekanisk simulator för JAS 39 Gripen
AbstractSAAB has for a long time used user controlled pilot models in ARES. ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.
Virtuell design av en testrigg för ett vindkraftverks drivlina - Analys av vibrationsdynamik
This bachelor thesis has the purpose to visualize and document the air movementsprovided by different ventilation principles in an operating theatre. The visualizationwill be made as simple as possible in a physical model. The model and thedocumentation should be able to use in educational purposes.The study is based on the two most common systems for airflow, currently used inoperating theatres. The first principle is displacement ventilation in which the air issupplied at low velocity along the floor. The second principle is vertical parallel laminarairflow in which the air is compressed like a piston from ceiling to the floor.A review of literature resulted in the choice of size, design, and scale factor for themodel, as well as choices of ventilation principles and airflows.
Pedagogisk dokumentation : En kvalitativ studie som beskriver hur utförande, utvärdering och presentation genomförs i praktiken
With the curriculum Lpfö98, and its revised version 2010, the demands for evaluation of the quality of the preschool have been emphasized. Accordingly, the activities need to be systematically documented, followed up and assessed, to be improved. Most importantly, this includes continuous follow up, documentation and analysis of the development and learning of the children. This is usually carried out by means of pedagogical documentation, but how this working tool should be used in practice is not totally clear for all pedagogues. The aim of this study was therefore to investigate how pedagogical documentation is performed, assessed and made accessible for the children, parents and staff-members, in practical preschool work.In the study, four pedagogues (two preschool teachers and two pedagogical mentors), working in two different preschools where the Reggio Emilia concept is practiced for pedagogical documentation, were interviewed using a semi-structured questionnaire.The informants described pedagogical documentation as a complex and time-consuming working tool, albeit necessary and helpful to fulfill the requirements of the curriculum.
Motiv och motivation bakom volonta?rism i extrema situationer. : En kvalitativ studie om Volunteer Function Inventory och dess beha?llning som analysverktyg.
This study is based on the notion that the most widely cited and used instrument for assessing volunteer motivations, the Volunteer Function Inventory (VFI), might not be sufficient in its aspiration to aid, streamline and benefit the recruitment and retention process within volunteer organizations. Understanding volunteers? motivation is a crucial component in the process of securing future volunteer engagement in a world where their efforts are desperately needed.This study aims to explain motives and motivation behind volunteer efforts in extreme situations as well as to examine the dependability of the theoretical framework in relation to the forthcoming result, based on the following research questions:What motivated Swedish medical personnel to volunteer during the 2014 Ebola outbreak in West Africa?How could the motives and motivation of Swedish medical personnel be categorized in accordance with the Volunteer Function Inventory (VFI)?Is the Volunteer Function Inventory (VFI) a sufficient tool for analyzing the motives and motivation of Swedish medical personnel in the given case?The presented research questions will be answer through a qualitative theory-consuming study, based mainly on interviews. The interviews are, however, complimented by various written sources in the field of research.The result and subsequent analysis confirms the authors? notion on the VFI and highlights certain deficits in the tool?s execution and its succeeding result.
Utvärdering av fosforläckageefter stallgödsling med hjälp av lysimeterteknik : Evaluation of phosphorus leaching aftermanure application using lysimeter techniques
Based on laboratory studies with lysimeters, the concentrations of dissolved reactive phosphorus(DRP) and particulate phosphorus, which is the main part of other P (OVRP), has been studied inpercolating water. The experiment was conducted through irrigation of small soil columnscontaining clay topsoil from an experimental field in Västergötland. Three rain simulations wereconsecutively performed. DRP concentrations in the percolating water ranged between 0.2 - 0.3mg·Lclearly related to the phosphorus concentration in the soil, measured in a soil extract ofammonium lactate (P-AL). Concentrations of OVRP were relatively low and ranged between0.12 and 0.16 mg·Lwas not proven and the experiment may reflect how a relatively slow percolation of water mayrelease DRP.

In addition to the budget, all the teachers had 12 hours of professional development every year where they could attend conferences or their own choice of professional development.ConclusionWith the help in forms of professional development offered by the school, conferences, meeting with other teachers, and their own choice of development, the teachers instruction techniques could increase which could help the teachers to find the pupils? interest for different kinds of physical activities.KeywordsPhysical education and health, physical activity, SOC, sense of coherence..
Sa?kerhet och integritet i webbapplikationer : En orientering o?ver sa?ker utveckling
The use of Web applications is a growing area. While the possibilities and functionalities are increasing, so is the complexity of them, together with the threats against them because the complexity also opens up the application to vulnerabilities. It is therefore important for developers to know how a web application can be developed with security in mind.This study?s intention has been to create an introductory documentation of what kind of techniques that exists which can produce higher security, which methods there can be within the development process and what to think about when programming secure web applications. In this paper we have investigated how theoretical manuals in the IT security department handles that area, and interviewed two developers from two different companies to see how they use security in their web applications.The study has an exploratory technical perspective and does not explain how to practically use and interconnecting different security-enhancing technologies, but is more suppose to give a first glance at what is available and sow a seed for those interested to continue reading further about the subject.
Är det möjligt att förolämpa någon via en annons : En studie om annonsers effekt på konsumenter
Advertisements have become a regular part of our everyday lives. We walk past them on the street; we admire them on the subway and even invite them into our living room in between prime time showings. The reality is that in today's modern times there is no escaping the daily bombardment of advertisement. To distinguish themselves from the continuous noise of the industry, advertisers battle to find unique ways to capture the attention of consumers. But is it possible that some advertisers take their techniques to an extreme in the struggle to be remembered This thesis aims at investigating whether it is possible to offend a consumer through an advertisement due to its extreme simplicity.
Nationellt miljökvalitetsmål på lokal nivå : en fallstudie av arbetet med miljökvalitetsmålet Ett rikt odlingslandskap i Lunds kommun
Several thousand years of human impact on the landscape in the form of cultivation is the
reason to many nature- and culture values in the agricultural landscape today. Intensification
and rationalization has led to vast monocultures and has forced many farms to close down.
These trends have increased in the last years and constitute great threats to the values of the
cultivation landscape. The purpose with the environmental objective A varied agricultural
landscape is to protect these values.
The environmental action plan of the municipality of Lund (LundaEko) 2006-2012 is built on the
16 national environmental objectives. The purpose with this paper is to put together material that
the municipality of Lund can use in their work with modifying the local intermediate goals for
the environmental objective A varied cultural landscape. The overall issue for this paper is
?What has happened with the state of the cultivation landscape in the municipality of Lund since
LundaEko was approved in 2006?? The paper seeks to portrait the current conditions of the
following fields: meadows and pastures, organic farming, exploitation threats to agricultural
land, landscape elements with cultural values and species that are threatened.
Teknisk undersökning : Rötgaskammare för småskalig biogasproduktion
Biogas mainly consists of methane and carbon dioxide, where methane is theenergy-rich gas, and is naturally created when organic matter breaks down in absenceof oxygen, also known as anaerobic digestion. A biogas plant re-creates the anaerobicconditions inside a digester where the organic substrate is fed into and digests toproduce biogas. The gas is then used to produce energy by combustion and can beseen as a completely renewable fuel.Today, energy from biogas is used primarily by major stakeholders such asmunicipalities and thus the plants become very large with high investment- andconstruction costs. There are currently few small plants in Sweden, even though thepotential for agriculture and medium-sized to smaller farms to become self-sufficientin terms of electricity and heat is great. Farms have a natural stock of digestibleorganic material in form of manure or crops for example, which are constantlyavailable.
Reflektioner och kommentarer under den verksamhetsförlagda utbildningen
Syftet med studien var att undersöka vad sjuksköterskestudenter reflekterar över samt vilka kommentarer de fick under den verksamhetsförlagda utbildningen. För att kunna besvara frågeställningarna valde jag en kvalitativ innehållsanalys. Min metod för datainsamling var att jag analyserade sjuksköterskestudenternas loggböcker, som använts under den verksamhetsförlagda utbildningen. I resultatet framkom det att studenterna reflekterade mycket kring planering. Studenterna ville också vara självständiga men de kände sig ibland osäkra.
