In this report a systematic working procedure for risk classification of processing equipment from a maintenance point of view is described. How this system has been worked out is also an important part of the report. The classification system is adapted for use in complex processing plants. Preemraff Göteborg has been subject for the underlying study and application of the system.The system aims to give a good overview of the maintenance related risks at the plant. Furthermore, the analysis result is a good motivation for the suggested maintenance activities and as motivation for extended or decreased maintenance resources in total.

Samtidigt som traditionella religioner är på tillbakagång vänder sig allt fler människor till den magi och mysticism som kännetecknar new age. Forskningen har hittills närmat sig detta fenomen genom korrelationsstudier, demografiska kartläggningar och analyser av vad new age-anhängare tror på. I denna explorativa, induktiva studie berättade i stället fem kvinnor i halvstrukturerade intervjuer om vad deras new age-tro betytt för dem. Koncentrering av bärande utsagor i dimensionerna betydelse, tro relaterad till icke-tro, kunskapskällor och ontologi genererade fyra faktorer: existentiell trygghet som skyddar mot osäkerhet under livets gång och hämmar ångest inför livets oundvikliga slut; upphöjdhet genom insikter och medvetenhet som icke-troende saknar; antiintellektualism som betonar känslor och intuition på bekostnad av förnuft och logik; relativism som stipulerar att var och en har sin egen sanning. En funktionell modell som tydliggör hur faktorerna relaterar till varandra diskuteras, liksom resultatets integrering i ett teoretiskt ramverk och riktlinjer för framtida forskning..

Bakgrund: Methicillinresistent Staphylococcus aureus (MRSA) är en multiresistent bakterie som är svårbehandlad och kan orsaka vårdrelaterade infektioner. Varje år drabbas miljontals patienter av vårdrelaterade infektioner och hundratals patienter avlider för att vårdpersonalen brister i sina hygienrutiner. Syfte: Syftet med studien var att belysa hur sjuksköterskor kan förhindra spridningen av MRSA inom somatisk vård. Metod: Som metod tillämpades en litteraturöversikt som baserade på kvalitativa och kvantitativa vetenskapliga artiklar. Resultat: Ur analysen av datamaterialet framträdde två teman; höja kompetensen och förutse risker samt konsekvenser med sex underteman.

The Swedish debate regarding chat control highlights a value conflict between protecting the safety of children and preserving democratic rights such as privacy and freedom of expression. This thesis examines key arguments for and against the proposed EU CSAM-regulation, analyzing them through a normative argumentation analysis method. The analysis is based on the Swedish constitution, representing the common values of Swedish society. The study reconstructs arguments from four debate articles and evaluate them according to their relevance and validity, which makes up the arguments? total evidential strength.

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

GNT Group is a Nordic/Baltic wholesaler that distributes products in the IT, entertainment and home electronics sector. GNT is facing problems with inaccurate inventory levels which can lead to unnecessarily high inventory carrying costs or lost sales. Currently the decisions about when and how many to order are made somewhat arbitrarily by the responsible personnel. Their decisions are based only on some brief sales history and on experience. GNT wants to develop its ERP system to be able to support the purchaser in these and other related decisions.

This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes. Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient. In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.

Bakgrund: Bristande kommunikation och informationsöverföring är huvudorsaken till upp-komsten av vårdskador i hälso- och sjukvården. Komplexiteten i hälso- och sjukvårds organisat-ion i kombination med den mänskliga faktorn ställer krav på struktur i kommunikationen med hjälp av standardisering. En utmaning för hälso- och sjukvården är att implementera och studera standardiserade kommunikationsmetoder och studera effekten på patientsäkerhet och arbets-miljö. SBAR (Situation-Bakgrund-Aktuell Status-Rekommendation) är en kunskapsbaserad kommunikationsmetod, utvecklad för överföring av kritisk information i komplexa arbetssituat-ioner. Metoden hjälper till att skapa den struktur och förutsägbarhet som krävs för effektiv kommunikation i komplexa arbetssituationer såväl under normala förhållanden som under stress.

With gas prices persistently rising, electric and hybrid vehicles are getting more and more common and in recent years several new electric cars have evolved on the market. Although the energy consumption and low emissions are a huge benefit of the electric cars, they inevitably suffer from high prices, short range and time consuming recharging periods. To be able to withstand the competition it is important that electric vehicles not only can withstand general were and tare, but also the harsh conditions that ordinary cars is exposed to in daily usage. The purpose of this project is to develop a test methodology which replicate situations that could appear in daily usage of electric or hybrid cars and to understand the problems related to usage of electric cars in winter conditions. This paper also discusses the major differences between hybrid cars and electric cars.

This report is an inventory of the street lighting in half of the residential estates owned by Karlstad Bostads AB, a public housing company. The inventory was made to reduce the environmental impact of the street lighting. From the inventory an estimation of the total installed power and the energy consumption was made. The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

The purpose of this development project is to create a model for working with a high school project in Electrical and Energy Program. It should be conducted in a form like companies do according to the goals from The Swedish National Agency for Education. In order to fully perform this we use the concept of Young Entrepreneurship. The model is created according to the new conditions from The National Electrical Safety Board. There is now an exception saying that a student during education is released from the demand of employment that is the normal procedure where you are under supervision from a certified electrician. During the project there has been theoretical and practical examinations in order to clear out the advantages and disadvantages using this model, but also to examine whether it is useful in the future and to what extent it can be used. The result indicates that the model is useful and fulfills the goals from The Swedish National Agency for Education but that the model has its limitations and difficulties.

Humidity problems and poor ventilation are factors that we associate with poor indoor airquality which are known to negatively affect health. Such problems have decreased with timein Sweden but, in other countries this is still a major problem especially during winter. InChile, this is most common in the central regions of the country, especially the Strait ofMagellan. This issue is primarily due to surface condensation happening indoors which bringsabout dampness which facilitates the growth of fungus and stains, foul odors, metal corrosionand more. This is due to a combination of poor ventilation and insufficient forms of heatingalong with buildings which have no insulation.
