Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

Background: Competence development has become more important since the pressure on effectiveness is increasing and organisations are expected to constantly improvement. The design of the competence development activities is governed by the strategy which in turn will affect the outcome of the same. A knowledge intense business in which changes recently have taken place is healthcare, a business in which competition also has increased as a result from globalization. Due to this, it is highly important to take care of and improve the competence of individuals. According to this, we have found that healthcare is an interesting business to study with regard to competence development.

Inledning: Fysisk aktivitet och motivation i kombination spelar en viktig roll i det sjukgymnastiska arbetet. Fysisk aktivitet bidrar till ett flertal positiva effekter och för att undersöka vad som motiverar individer kan kategoriseringar vara till hjälp. Mycket av dagens hälsoarbete kretsar även kring de två snarlika begreppen prevention och hälsopromotion vilka kan vara en bidragande motiverande faktor till varför individer är fysiskt aktiva. Syfte: Syftet med studien var att undersöka vad som motiverade individer till att vara fysiskt aktiva, motsvarande eller överstigande rekommendationen för fysisk aktivitet. Metod: Sju anställda vid LTU som var medlemmar i StiL intervjuades.

Syftet med denna pilotstudie var att skapa hypoteser om vilken påverkan en internetbaserad återhämtningsfokuserad stressintervention kan ha på beteendemönster och generellt hälsotillstånd. 22 vuxna svenskar rekryterades initialt till studien. 15 individer valde att fullfölja hela interventionsprogrammet. Mätningar med internetbaserade frågeformulär genomfördes innan interventionens start och efter interventionens slut. De primära ändpunkterna för mätningarna utgjordes av beteendeförändringar (frekvens av återhämtningsbeteenden) och kliniska effekter (upplevelser av stress och återhämtning).

Marinediesel has, to meet there customers needs for a suitable sterndrive to powerboats, developed a prototype. The prototype is currently in the testing phase. The opportunity to test the sterndrive under load inside the workshop has not previously been possible. Until now the drive has been tested in a test bench without any load on the propeller axle. The prototype has also been tested under real conditions mounted on a boat.The idea with my thesis was to create a test bench that can run around the clock in order to be able to test things like wear and service intervals and other things that require that the test interval is long.

Sår och sårvård har existerat lika länge som människan levt. För att kunna utföra sårvård som täcker patientens vårdbehov är sjuksköterskan i nuläget dåligt utrustad. Sjuksköterskan har liten kunskap om prevention, bedömning och behandling av sår. Syftet var att belysa faktorer som påverkar sjuksköterskans sårvård. En litteraturstudie utfördes enligt Fribergs modell.

This thesis deals with numerical simulation of earth pressure against tubular bridges in the software Plaxis. Plaxis is a FEM (Finite Element Method) software based on numerical calculations for which approximate solutions are developed through an iterative process. The program is specifically designed for soil and rock mechanical tests, such as voltage and deformation calculations in soil.The Royal Institute of Technology conducted in 2005, field tests on tubular bridges of corrugated steel, which was part of Ersa Bayoglu Fleners PhD (Bayoglu Flener, 2009). She studied how two different tubular bridges deformed during installation and filling. Tests and measurements were made during filling.

The purpose of this study is to gain a deeper understanding of women's violence against men in intimate relationships, get an idea of ??what forms of expression that this type of violence has and to highlight the men's experiences of violence.There is little scientific research in the field in Sweden. Crime Prevention Council has determined that eight percent of all complaints involving domestic violence in 2010, reported by men over 18 years. You can only speculate on how large number of unreported cases is among abused men. The international studies highlight that the abused men feel ashamed of having been subjected to violence by a female partner.I have been based this essay on two theoretical premises, Per Isdal theory of "violence perspective" and Elaine Bergqvist's definition of the suppression technique.The study was conducted through a qualitative content analysis.

This paper aims to, through a literature review, examine how to best design and adapt calf huts to meet the calf's physiological requirements and reduce the infection pressure for enteric and respiratory diseases. It illuminates how the calf relates to different temperatures and climate, which temperature control mechanisms it uses and its ability to perform these regulations, as well as providing a summary of the past decades´ research on the calf huts housing system. These two theory chapters, along with a concluding discussion, provide a better understanding of how to, especially in temperate climates, design the most suitable calf hut, which cater to the calf's both thermal comfort and physical health. The literature suggests that the calf's own temperature control works well to counteract the temperature outside the desired range, and that one of the most important factors rather is ventilation of a calf hut, which reduces moisture and pathogens. The conclusion of this paper is mainly that there is not an obvious way to place and construct a calf hutch and that most design principles contribute to both positive and negative effects simultaneously.

Syftet med vår undersökning var att ta reda på hur kuratorer i högstadie- och gymnasieskolor arbetar preventivt och hälsofrämjande med ungdomars psykiska hälsa samt hur kuratorers samverkan med andra ser ut. Vi ville också ta reda på vilken problematik som enligt kuratorerna är vanligast samt orsaken till detta. Vi har använt oss av en hermeneutisk utgångspunkt med kvalitativ ansats, baserad på intervjuer med kuratorer. I resultatet har det framkommit att de ungdomar som har kontakt med kuratorn ofta kommer dit genom en lärare, skolsköterska eller av egen vilja. Den problematik som tycks dominera är till exempel trötthet, stress, hemsituation eller kamratrelationer.

In Sweden approximately ten percent of all children grows up in a family where at least one parent is having an alcohol related addiction. Since 1998 the development of group activities for children in this situation has been immense. The aim of group activities is to break the child's isolation and make them feel that they are not lonely in their experiences, give them knowledge about addiction and relive the pressure of guilt and responsibility.In a comparative study we examined studied how two different group activity models one with the conception of illness and one without, use the children's network to support the group process. The aim was also to find each models definition of the "normal family", since we understood the groupactivity as a part in the normalization process. We reached our aim through interviews with group leaders and by literature studies.

Inledning Postoperativt illamående och kräkning är ett välkänt problem efter sövning medgenerell anestesi och drabbar mellan 20 % och 30 % av alla patienter som blir sövda. För attminska de obehag och lidande som illamående och kräkning kan ge den postoperativapatienten vore det optimala att profylaktiskt behandla de patienter som löper en stor risk attdrabbas av postoperativt illamående och kräkning. För att avgöra hur hög risk patienten har attdrabbas av postoperativt illamående och kräkning beskrivs i litteraturen ett flertalriskbedömningsmodeller som sjuksköterskan kan använda sig av. Syfte att granska omanvändandet av en riskbedömningsmodell kan minska frekvensen av postoperativt illamåendeoch kräkning hos patienter som erhållit generell anestesi. Metod Litteraturstudie.

Background: Postoperative infections are a serious patient safety problem and affects about 3 % of all patients undergoing surgery. The consequences are prolonged hospital stays, high social costs, increased use of antibiotics and impaired quality of life for the patient. It has been shown that postoperative infections may be caused by contamination already in the operating room. Today we know that there is growth of microorganisms on the instrument table´s top, but there is a research gap about the instrument table's edges.Aim: To examine if the sterile drape on the instrument table´s edges are sterile after finished surgery.Method: Contact plates are printed on strategically selected areas on the sterile drapes top and edges. In the pilot study, a total of 51 cultures were taken at the end of three operations which lasted over three hours.Results: Growth on the top surface and the edges of the sterile drape were detected.

Nowadays, the world around us is changing faster and faster, the globalization is increasing and harder competition puts extra pressure on companies to be more innovative than ever before. One of the fastest changing industries is the IT industry where the actors always have to be up to date to keep their competitive advantage. The authors want to find out what makes some companies in this industry more innovative than others by examining what internal elements that are necessary for innovation. Much research has already been carried out within the field of innovation and especially about innovation management, although less research exists about smaller, non high tech service companies. Therefore the authors also tries to find out how applicable today?s theories are on this special field and thereby fill a smaller gap in today?s research.

The aim of this study was to describe the mental and social causes to obesity among children and adolescents, their consequences and what preventive interventions that are used. The method used by the authors was to search for scientific articles in the database Medline, using the keywords: obesity, overweight, child, body image, social, family, school, depression, nursing, quality of life, social support, prevention and support. The study was performed as a literature review, with a descriptive design, and the result contained 22 scientific articles. The main result of this study showed that obesity among children and adolescents is not only an individual problem, it affects the whole family. The main causes to obesity among children and adolescents are the socioeconomic status of the family, their lifestyle, and even gender to a certain degree.
