Anestesisjuksköterskors upplevelser av sin fysiska och psykosociala arbetsmiljö
Health care is increasingly complex, which increases the demand for knowledge and expertise. Despite this, the share of specialized nurses, including anaesthesia nurses, has decreased from 65% to 48% from year 1995 to year 2008, according to statistics from the National Board of Health and Welfare (Socialstyrelsen) in 2010. Studies indicate that there may be various factors in the work environment that anaesthesia nurses, choose to leave the anaesthesia profession. The purpose of this study was to examine how anaesthesia nurses experienced the physical and psychosocial work. The study was conducted as a descriptive study with qualitative approach.
Optimering av sintrade kugghjul
Powder Metal (PM) gears are machine element components which operate under the same principle as conventional gears, but, due to their intrinsic material characteristic need to be designed slightly different, and its manufacturing process offers advantages previously unobtainable by conventional steel gear manufacturing methods. The use of PM in similar applications, such as synchronous hubs, makes them a suitable candidate for production in such material. The current master thesis work focuses on gear design using PM by utilizing finite element method (FEM) to reduce weight and inertia taking into account root bending strength and tooth deflection.First a topological optimization is used to determine feasible candidates for different web designs which have as objective to reduce volume, similar topologies were shown during different loading conditions; and hence, this topology was chosen as a suitable candidate. A shape optimization of the topological candidate was performed having as state variables root bending strength, independent for compressive and tensile side of the tooth loading; and tooth deflection, which in concept can be correlated to static transmission error (TE).Another aspect in this thesis analysed is the possibility to incorporate non-trochoid root geometry, a trochoid root is always present when machining with a hob, into the gear root and hence reduce the stress concentration here. Due to the use of PM, a non-symmetric optimized root can be achieved and hence be optimizing compression and tension.Results showed significantly lower inertia, for example certain results showed 40% reduced when compared to solid gear, with adverse effects as increase in tooth deformation and increase in maximum principal stress.

What absences are there today concerning the communication of the customer?s needs within the organization? How can the communication of the customer?s needs within the organization improve?The aim of this study is to describe and analyse how the transmitting of the customer?s needs concerning soft product quality is made today in the case company and to reach any improving suggestions.
Nu kan jag mycket mera : En liten studie i hur delar av Europeisk språkportfolio kan fungera som stöd för formativ bedömning i ämnet engelska, år 4.
The aim of the study is to show how a selected part of the European Language Portfolio, ELP, can support the assessment process for teachers. All the checklists at level A1 and My Language Goals from the Language Biography, a part of the ELP, are implemented and communicated in teaching in a 4th grade class of students. Two teachers are interviewed and both of their classes are compared in the study. One group worked for two weeks with the selected part of the Language Portfolio and the second group followed the regular curriculum for the same period of time. The teachers are interviewed before and after the ELP through support of mind maps.Results show that by using checklists at level A1 and My Language Goals students become aware of their own learning process.
Nya landskapselement i Infra City :
My work deals with large scale design of the urban fringe. The thesis is divided in three parts; ?Current viewpoints?, ?Infra City ? conditions ? and ?Infra City ? project?.
In the first part, I go through the history of trade shortly. Then I discuss the concept of nature, which ends up in a linkage between natural science and aesthetics in landscape architecture. The link between those two makes a project stronger and more multifunctional.
The object of my case, Infra City, is a mall situated north of Stockholm on both sides of the E4 motorway going to Arlanda airport.
Vid min sida : en undersökning av människans relation till hästen under vikingatid och medeltid
The purpose of this essay was to try to understand the relationship between the horse and man during the last part of the Iron Age and trough out the Medieval Age. To be able to get a result I investigated the horse's tending, work within agriculture, riding, warfare, breeding, to stable horses, oxen, sports and hunting, eating of the horse and age at slaughter and more. The results showed that the horse's position changed from the later part of the Iron Age throughout the Medieval Ages and in different ways for, respectively, the elite as for the peasant culture..
Kvinnors upplevelser av att återgå till det dagliga livet efter en hjärtinfarkt
During the 1960s and 1970s an increased interest in Native Americans can be seen in Sweden, e.g. through the establishment of organizations such as the Indian Club of Sweden. The aim of this thesis is to study the portrayal of Native Americans and its role through Albin Widén, a Swedish author, ethnologist and member of the Indian Club, and his non-fictional works on the Swedish migration to America, Swedish-America and Swedish contacts with Native Americans. The study is divided into four parts. The first part looks at the portrayal of the Native Americans in Widén?s writings, in comparison with Euro-Americans? and Europeans? traditional stereotypic images of a good and a bad Indian.
Är sociala medier mest ett hinder? Ungas lärande i sociala medier
A large part of the daily life today means being active online and to take part in the interactions that occur there. The accessibility which social media brings, means that you can reach and be reached in several ways and there are many different ways in which information can be disseminated. Social media supports the learning process. The aim of this study is to examine how upper secondary schools students' use of social media and how it can be used as a tool for informal learning. Our study is based on the socio-cultural perspective where interaction and social cohesion is a big part.
Geometri: geometrins historiska utveckling och hur geometrin presenteras i läroböcker för gymnasiet (1962-1999)
Den här C-uppsatsen, som handlar om geometri, har tre ingående delar. Den första delen berättar geometrins historiska utveckling från de första Babyloniska skrifterna via kända matematiker som Pythagoras och Euklides fram till utvecklingen av den icke-euklidiska geometrin. Den andra delen förklarar mer ingående några hållpunkter som uppmärksammades ur geometrins historia. Denna del beskriver Euklides axiomatiska framställning och bevis av Pythagoras sats, konstruktion med passare och linjal, Apollonius kägelsnitt samt en inblick i grunderna för projektiv geometri. I den avslutande delen har en jämförande studie gjorts av fyra olika läromedel för gymnasieskolan.
3D-modellen som kommunikationsverktyg
If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.
Män, förlossningsrädsla och Auroraverksamhet
Research has shown fear of childbirth to be as common among men as women, but the phenomenon has not been as studied among men. Some men have trouble talking about their fear and therefore don?t get the support that they need. Where to go to get help is not so obvious for these men. The name mostly used for this clinic is Aurora.
Kunskap inom socialtjänsten: en studie om kunskapssynen inom IFO i en medelstor svensk kommun.
The purpose of this study was to examine knowledge within the social services. We narrowed the study down from general knowledge to scientifically produced knowledge and how the social workers relate to such knowledge. We aimed to see how the social workers perceive different knowledge and how they relate to the different sources of knowledge. We also examined the different factors that will enable and motivate social workers to stay updated with scientifically produced knowledge that is relevant to their work. We also examined what limits the ability or motivation for renewing ones knowledge.
Rabies : en utmaning för Indien
This literature study describes the ways in which the spread of rabies can be prevented in India, what guidelines are set and also which methods have proved most effective.
Every year rabies causes the death of around 20 000 people in India, which makes the prevalence in the country the highest in the world. The main source for human infection is bite wounds from infected dogs. People and animals can be vaccinated both prophylactic and post-exposure prophylactic (PEP), despite this the disease continues to claim high number of victims. The majority of those dying are young men and children from the poorer part of the population. Knowledge among the Indian population on rabies and its transmission routes, wound care and vaccinations is very limited.
Förskolegårdens miljö : Inbjuder gården till aktiviteter som stimulerar barnets motoriska utveckling?
Through observations of the childrens play, I have made notes of all activities at the pre-school playground. The intention of the observations was to see if the playground environment invites and stimulate the childs motorie development. The study will be a part of a future planning work of the preschool environment.The results show that the pre-school playground environment invites to physical activities that stimulate the childs motory development. The variation of activities is dependent on the design of the landscapes. The pedagogues taking part of the childrens activities are one of the factors which contributed to the childs choice of activity.The preschool plays an important part in the childrens development so it is important that all personnel have basic knowledge on the importance of outdoor activities.Keywords: Fundamental movement, motorie development, preschool playground, outdoor enviroment.
Planning is Everything, Plans are Nothing : - En kvantitativ studie om styrelsearbete och långsiktig planering i byggnads- och anläggningsföretag
The goal of this paper is to analyze the influence of the EU on Turkish democracy. In order to achieve this aim, the paper concentrates on three areas, as representative institutions, opposition parties and freedom of expression. The impact of the EU on Turkey has been more explicit during the last decades. In particular since 1999 when the country became a candidate for membership, and that will eventually lead to Turkey joining the European Union. Thereby this paper will examine the demands EU set up for the country and how Turkey accomplishes these criteria.
