Remittera till akutmottagningen eller inte? : Sjuksköterskors uppfattning av beslutsfattandet på vård- och omsorgsboende.

Background: High demands are today placed upon Swedish elderly care nurses as more elderly live with multimorbidity while the hospital bed capacity is becoming lower. Aim: The aim of the study was to explore nurses? perception of decision-making in situations with acutely ill patients in nursing homes and which factors may influence the decision about transferring patients to the emergency department or not. Method: This is a qualitative study with a phenomenographic approach. Semi-structured interviews have been conducted with 11 nurses working in nursing homes. The data analysis was based on Dahlgren and Fallsberg (1991) data analysis. Result: Three different description categories were presented, which describes variations of the nurses? perceptions.Feeling comfortable in making the decision; which involved the nurses feeling confident in the decision-making about transferring patients to the emergency department or not.Hesitant in making the decision; which described how nurses perceived the decision-making as problematic, with regard to transferring patients to the emergency department.Many wishes to consider in taking the decision; which explained how nurses? decision-making was influenced by requests from the patients or from people close to them.Conclusion:  The study reflected how  supporting and aggravating factors could influence how nurses in nursing homes perceived the decision-making and how nurses have to take in consideration different opinions concerning the decision making process of transferring patients to the emergency department or not.

Solenergi på Nya Karolinska Solna

In today?s society climate change has grown to one of the largest global issues. To reduce emissions of greenhouse gases, large changes of the energy system are required. An increasingly popular solution is investments in local production of renewable energy resources like wind, solar or geothermal power. The following report examines the possibility for implementing a solar power plant on the new hospital Nya Karolinska Solna. Two different technologies for extraction of solar energy has been studied, solar thermal collectors  to meet the need of heating and solar cells to satisfy the need for electricity linked to operating the hospital building.

Energieffektivisering av Åhlénshuset i Umeå : Utredning av åtgärder för ventilation, värme och kyla

Sweden is a country that has made some progress in developing energy efficient solutions. The problem in Sweden is that many houses and apartment buildings are old and have inefficient ventilation- and heating systems. This energy is lost when systems are inefficient, which then results in huge economic costs. Luckily, more and more people are becoming aware of this, which means that Sweden is on track to become even better within energy efficiency.Energy use for the housing- and service sector amounts to 166 TWh of total use at 616 TWh. Without distribution and conversion losses, these figures show that the housing- and service sector accounts for almost 40 % of the country's total energy consumption.

Självskattning av exekutiva funktioner vid kognitiv träning : En utvärdering av The behavior rating inventory of executive functioning - self report

Syftet med uppsatsen var att undersöka självskattad exekutiv funktion som ett alternativt mått för att utvärdera effekter av kognitiv träning. Som utfallsmått valdes The behavior rating inventory of executive functioning - self report (BRIEF-SR). Vidare användes blandad design med för- och eftermätning samt tre oberoende grupper. Gymnasieelever (n = 63) delades in i; aktiv träningsgrupp, aktiv placebogrupp och passiv kontrollgrupp.

Saklig grund för uppsägning i samband med samarbetssvårigheter

Abstract Co-operation difficulties in the work place can be a problem serious enough. Co-operation difficulties can occur between employee and employer, as well as employees among themselves. Irrespective of between which individuals the co-operation difficulties occur, it will have negative consequences. These can consist of, for example that individuals might suffer mentally, inproductivity and also an unwished economic disadvantage for the employer. From the employers? side it is pointed out that it is important with employees who are possible to co-operate with in a satisfactory way.

Tidsupplösning vid miljövärdering av fjärrvärme : Kontorsbyggnad med solvärmeproduktion - en fallstudie

The demand for environmental assessments on buildings and energy consumption is increasing as well as the energy performance requirements for buildings. At the same time it is increasingly common with self-producers of heat and electricity generation.The main purpose with this master thesis is to investigate how time resolution affects the environmental assessment of energy consumption in office buildings connected to district heating (DH). Environmental assessments were done with both attributional LCA and consequential LCA with system expansion.Fortum´s DH system in Stockholm was analyzed and district heating production was simulated in a Matlab-model. Greenhouse gas (GHG) emissions for the production were calculated. The heat demand of the office Gångaren 16 in Stockholm was simulated in IDA ICE.

People who since 2008-01-01 until today, have acted as a buyer of forest land. 80 responses were achieved and the result shows that the majority of buyers have a high gathered satisfaction..

En systemlösning för en framtida fjärrvärmeutbyggnad i Täby : ur Fortum Värmes perspektiv

At the moment in central Täby there are small district heating network operated by Fortum Heat. The distribution network has an annual heat demand of about 70 GWh, which is supported by the network's two plants, Galten and Farmen. Täby as a region is rapidly growing and there are grand plans to develop the area. Estimated market potential for a future district heating expansion in Täby is very high and as early as in 2007 Täby decided to invest in a large-scale expansion. In autumn 2009 Täby did a procurement process, known as the ?Täby initiative?, to find a partner that could implement those expansion plans. To secure a cheap basic production the partner also need to build a power plant at Hagby recycling center. Despite high interest during initial state of the process, only one procurement offer were received and Täby suspended the contract in March the following year.

En jämförelse ur energisynpunkt mellan roterande värmeväxlare och frånluftsvärmepump i universitetsbyggnad

För att tillgodose den studerande KTH byggnadens framtida krav kommer det befintliga ventilationssystemet att bytas ut. Två olika möjliga värmeåtervinningssystem har jämförts ur fjärrvärmebehovssynpunkt. Det befintliga systemet med vattenburen batterivärmeväxlare har en låg värmeåtervinningsgrad och Akademiska Hus önskar system med högre värmeåtervinning. I byggnaden har roterande värmeväxlare och frånluftsvärmepump för uppvärmning av tilluften jämförts. Då värmeåtervinning från dessa system inte är tillräckligt kommer fjärrvärme att används.I beräkningarna jämförs fem roterande värmeväxlare mot varierande antal frånluftsvärmepumpen.

Sekundärnät för lågtempererad fjärrvärme

Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.

Lönsamhetsanalys av tekniker för utökad elproduktion i kraftvärme : Med hänsyn till elprisets variationer

This thesis aims to examine the viability of various techniques for increased electricity generation in CHP plants and the effect of electricity price fluctuations on the profitability.The techniques examined are fuel dryer, pellet production, methane production, combined methane- and pellet production, seasonal heating storages in caverns and pit heat storages and condensing tail. Using Excel and Matlab, the prerequisites for investment costs, revenues and expenses were calculated.What affects the price of electricity is a combination of economic and technological development, energy prices, economic structure, population changes and weather. Different scenarios for the electricity price were therefore examined. In the base case, the electricity price was given by the Nord Pool electricity price statistics of area three in 2011. Thereafter, WiMo was used to design the electricity scenarios for 2030, which was then applied to the data to obtain the viability of various scenarios. The techniques examined were found to give greater profits to the CHP plant by increasing and optimizing the production of electricity.

Myt och vetenskap om kastration av tik

This is a literature study in which I investigate if there are scientific studies that form the basis of the Swedish dog world views concerning the spaying of bitches. The positive impacts are said to be reduced problems with pseudopregnancy, reduced risk of pyometra, reduced risk of mammary and uterine tumors, an earlier cease of bone growth, a more active and happier dog and a bitch who is more tolerant of other dogs. The negative consequences are said to be urinary incontinence, increased aggressiveness, lower metabolism and the increased risk of obesity, a more lethargic individual and altered coat.There are studies indicating that spaying reduces behavioral problems associated with heat and pseudopregnancy. Assuming no ovary tissue persists after the procedure, and there is no progesterone production, the risk of pyometra decreases. Early spaying, before the first heat, reduces the risk of mammary tumors.

Replikering av komplexa kunskapssystem : En fråga om organisatorisk integration

Background: Many authors consider knowledge to be a significant source for competitive advantage. Replicating companies found their competitiveness on an ability to leverage its knowledge base by replicating its business model in new contexts, a process often referred to as the McDonalds approach. Several authors emphasize that an efficient method for knowledge transfer may increase the risk for imitation. Purpose: The purpose of this study is to examine in an explorative manner how strategies for replicating complex knowledge systems are employed and developed. Furthermore, our ambition is to explore the notion of replication strategy.

Erfarenhetsöverföring inom markarenan med stöd av simulatorteknik. : En studie av StriSimPC.

One of the main tasks of the Swedish Armed Forces over the past few years has been International assignments, which increased the importance of the Lessons Learned process. Methods of simulator training with computers have become more frequent and the technical ability to collect digital data from sensors has been developed as well. This work demonstrates how the experience of Lessons Learned can be communicated with the computer simulator StriSimPC and how modern technology in future support experiences from the Lessons Learned process at the tactical level in the Army.Currently knowledge sharing consists of several processes and strategies in the Swedish Armed Forces. This is done by written reports, oral presentations and different practical exercises.This case study shows the functions of the simulator StriSimPC, methods of training and how it is used today. The study also describes the future opportunities, where digital metadata acquired from the modern combat vehicles could contribute sharing of experience in the Lessons Learned process.The summarized conclusions indicate that StriSimPC can combine the two strategies for personalization and codification of knowledge transfer to reach a higher level of learning.
