Hälsosamtal i elevhälsovården : Vad uppfattas som ett positivt och betydelsefullt hälsosamtal utifrån elev- och skolsköterskeperspektiv?
The aim: was to describe and compare a group of experts and critical care nurses' agreement in detecting delirium in intubated, ventilator treated patients with sedation / analgesia, before and after an in house training intervention with the instrument Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).Method: A quasi-experimental study, one group pretest - posttest design. A convenience sample of 17 critical care nurses in a general intensive care unit included. To detect delirium the instrument CAM-ICU was used, 21 paired tests before and 22 after an educational intervention.Main Results: The results showed that after an in house training intervention sensitivity and kappa coefficient improved of the characteristic 1 "acute onset and fluctuating course," an improvement that was significant. In other features, and overall values were signs of numerical improvement and deterioration in sensitivity, specificity and kappa coefficient but no significant change.Conclusion: Implementing a new instrument for detecting delirium in clinical practice requires education and follow-up. A small sample of critical care nurses with varying ability to use the new instrument and the fact that patients' status may change rapidly making it difficult to draw any conclusions from this study.
Lärande organisation ur ett medarbetarperspektiv : En kvalitativ studie om medarbetarnas uppfattningar om det gemensamma lärandet på en förskoleenhet
The purpose of this essay is to develop knowledge about how learning among employees is perceived to occur practically in a pre-school unit seen as a learning organization. From an employee perspective the intention was to gain an understanding of how they perceive the organization regarding employee learning in the workplace when it comes to in which contexts and what conditions that enable collaborative learning. Because learning organization is mostly a vision from a management perspective thereby it should in this case mostly be viewed as the context in which the employees work in.The essay is based on a qualitative research approach with eight semi-structured interviews. It was based on hermeneutics as method of analysis with the intention to gain an understanding of the employees' subjective perception. It is a case study on a selected pre-school unit in Stockholm.
Effect of cow traffic system on cow performance and AMS capacity
Robotic milking in Automatic Milking systems (AMS) is proposed to reduce manual labour and at the same time increase milk yield by increasing milking frequency. In order to increase milking frequency, it is essential to have well-functioning cow traffic. Investing in an AMS is a great capital investment for the farmer, thus it is of major importance to ensure maximal AMS capacity. This study investigated the effect of the traffic systems Feed First? and Free cow traffic with and without waiting area (WA) on cow performance and AMS capacity.
Klimatsimulering av ett kontorsrum : Hur de termiska stigkrafterna påverkar ventilationseffektiviteten
AbstractIn urban societies people spend more and more time indoors, which put great demands on the indoor environment. If the ventilation is to manage the removal of unwanted substances in the indoor air, a good mixing of the air is required. The question arises that, whether the buoyancy forces will counteract a good mixing of the indoor air or not?This report aims to clear up the difficulties whether you need to consider the buoyancy forces or not, when adjusting a ventilation unit. For studying the indoor mixing of the air a two dimensional model is constructed in COMSOL Multiphysics.
Elevers syn på klimatfrågan : Klimatundervsiningen i skolan
The aim of this study is to find out in which way the education about climate in school is taught and how the students experience the world situation today. There are various theories about the greenhouse effect and its origin and these theories should be addressed to ensure that students get a broader understanding of how climate change occurs. This includes the natural phenomena and also the human impact on climate change. Students in school are a source of concern that only human are the cause of global warming, and know little or almost nothing about the natural phenomena of global warming. I will mention what has emphasized in the national steering documents in the case of environmental education at school.I have used a qualitative method, where interviews and document analysis were used as techniques. The interviews took place with five students in ninth grade and with three science teachers in the same school..

These are shown to be in conflict with the economical perspective of the private sector.
Torkningstekniker i den preoperativa handdesinfektionen - en experimentell studie
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.
Omloppstid för returenheter
Cycle time has a direct influence on number of returnable crates needed and therefore a crucial parameter for cost structure and pricing of the user fec in the pool system.For providing the growing market, number of crates has to increase as well as the utilization of existing crates. To accomplish this aim, cycle time for the whole supply chain has to be fully unravelled and understand.The purpose is to map cycle time and stock movements, to see how, where and when crates are being used in the supply chain. The goal is to make a method of cycle time calculation, together with suggestions of improving the pool system and decrease cycle time.The study has been a combination of qualitative and quantitative research and comprises the three biggest wholesalers in Sweden; ICA, Coop and Axfood. Furthermore have 65 grocery shops, connected to the wholesalers, been investigated and mapped.The study has come to a conclusion that cycle time for an average returnable crate is 19 days. The full-size and half-size crates have a bit longer cycle time, 21-22 days, while Dual Height-crates and shallow haif-size crates have 17-18 days.
Power supply monitoring for wireless sensor platforms
Most of the portable electronic devices use a battery as a primary power source. Nowadays, when the applications are becoming smaller and smaller and more power efficient, the designer needs to concentrate more on reducing power consumption, using secondary power sources and introducing power storage devices. Multiple power source availability and a power storage device on the board will make the applications much more useful and efficient in everyday use. This thesis proposes a power supply unit (PSU) for wireless sensor platforms which is capable of supplying a sensor node with energy from multiple sources, as well as status information from the PSU. Present power storage devices, like electric double-layer capacitors (EDLCs) and batteries, have become more and more common as their characteristics have developed.

Bakgrund och syfte: Intresset för enteral administrering av probiotika i förebyggandet av infektioner och diarré har på senare tid ökat. Nosokomiala infektioner och diarré är ett stort problem hos intensivvårdpatienter. Syftet med denna studie var att undersöka hur enteral probiotika påverkar sjukdomsförloppet hos intensivvårdspatienter, med avseende på mortalitet, infektioner totalt, ventilatorassocierad pneumoni (VAP) och diarré.Metod: En systematisk litteraturstudie med sökning i Pubmed och Cinahl genomfördes med följande Meshtermer; probiotics, lactobacillus, critical illness och intensive care unit. Därefter genomfördes en metaanalys av randomiserade kontrollerade studier, utförda på vuxna intensivvårdspatienter, där man jämfört patienter som erhållit probiotika med patienter som fått placebo eller annan behandling.Resultat: Totalt 15 studier med sammanlagt 1293 patienter inkluderades. Ingen signifikans med avseenden på mortalitet, infektioner totalt, VAP och diarré kunde utläsas i metaanalysen.
Hantering av verksamhetskrav : Utredning av hur hantering av verksamhetskrav från kunder kan förbättras på Saab Aerosystems
Saab Aerosystems have had one dominating product, JAS 39 Gripen, and one dominating customer, FMV, for a long time. The operations management system at Aerosystems is adjusted for development of Gripen and as the business unit is trying to enter new markets with other products and customer the operations needs to be adjusted to fit the development and manufacturing of these products as well.The purpose of the master thesis has been to investigate how Aerosystems is managing requirements on operations from external customers and how to make improvements within this area. The aim has been to carry out a situation analysis to identify where improvements are possible and then produce proposals for improvements through studies of literature and other business units. The thesis also include a study of knowledge transfer within the business unit to investigate how this can be applied to improve the managing of requirement on the operations.An extensive interview study has been carried out in which interviews mainly have been conducted with employees at Aerosystems, but also at Saab Avitronics and Saab Aerostructures. The reason why these business units have been examined is because they have carried out a large number of successful businesses with external customers, which also are potential customers for Aerosystems in the future.The interviews have been analysed to identify strengths, weaknesses, opportunities and threats with the present way of working.
Realtidsstyrning av IP-kamera
The final thesis named Tracking in Sensor Networks was created by the company Instrument control Sweden. The thesis work is to create a plug-in to an already developed software pro- gram, SkyView. Via the software program one should be able to control an IP-camera from AXIS, model 215 PTZ, with the appropriate protocol over a network. An Application Programming Interface, API, was used to easily control the camera through SkyView. The interface is called VAPIX and is used to all cameras from AXIS.
TOMO Hugglink
Tomo Hugglink (TOMO Skog) is an innovation for harvest and transport of biofuels. The system consists of a truck, a chipping unit and crane mounted on a link and a wood chip trailer. The system works in such a way that the chipping unit is disconnected and placed on the site and wood chips are loaded directly into the wood chip trailer.The aim of this study was:- To examine the performance of the TOMO Hugglink system under different conditions such as the size, placement and quality of the pile.- To calculate the cost per raw ton for two vehicle combinations at different transport distances and to examine the effect of a reduction in set-up time and an increase in load weight.- To identify possible improvements with the TOMO Hugglink system.A time study was conducted within the thesis work to make it possible to determine production and time consumption. In the subsequent economic analysis the cost per tone at different transport distances was calculated for two different lorry concepts. Furthermore the effect of a reduction in set-up time and an increase in load weight was calculated.Under current conditions the utilization of the chipper is low and only 29 % of the total system time is occupied by chipping.
I linje med styrdokumenten? - en fallstudie i tre läromedel i engelska
This study focuses on an analysis of three text books in English, Prime Time, Second Time, and Third Time, written for Swedish pupils between grade seven and nine. The main focus of the study is to investigate to what extent the books may be considered to follow the steering principles of the Swedish education system. The theoretical backbone of the essay is centred on the construction and maintenance of stereotypes, and is written from a social constructivist point of view. In this context, I also reason around power relations and norms in the Western society ? arguments which I, in the main analysis, apply to the books in question.
Olssons trädgård : ett examensarbete som handlar om att lyssna när en plats berättar
This master thesis is about a place that has a story to tell. Olsson?s garden came about when Mr Carl Oscar Olsson acquired a piece of land in Landalabergen in the beginning of the 1930's and at that time he started his industrious work of uniting much of Sweden's flora in his garden. Since the very beginning Olsson's garden has played a lot of different rolls in a variety of situations and meant different things for different people.
Today one can find traces from Mr Olsson's life and deeds in the garden.
