Hälsorelaterad livskvalitet hos partner till personer med afasi : En undersökning baserad på hälsoenkäten SF-36 och semistrukturerade intervjuer
Around 30,000 people in Sweden suffer stroke every year, out of which about 12,000 end up with language difficulties, aphasia. Behind every person with aphasia there are significant others whose lives are also affected. Studies of how aphasia affects the health of these people are few. The overall aim of the present study was to examine how significant others of people with aphasia perceive their life situation, and how their quality of life is affected by the illness of their partner. Spouses of people with aphasia were contacted through aphasia groups and the Swedish Aphasia Association.
Optimalt ekologiskt : att gestalta praktfulla parker som kan skötas på ett hållbart sätt
This is a graduate work at the Swedish University of Agricultural Sciences, The Department of Urban and Rural Development, Ultuna. The purpose of this paper has been to find out and describe principles for designing parks that offers good recreational and aesthetical values and require little amount of carbon dioxide emissions during their maintenance. The purpose has also been to see if it's possible to use city wastewater in some extent to assure the plants water supply and to find other means to make it less necessary to use purified water for watering.
Recently made studies as well as older ones show how important green areas are in dense city structures both from a health and a climate perspective. Trees and other plants adsorbs different forms of air pollution and can also lower the temperature in the surrounding area through their transpiration.
Assuandammens påverkan på Nilen, Egypten
Regulation of rivers by dams and reservoirs is a good example where anthropogenic impact could be considerable both in the local environment, but also has major implications upstream and downstream. This study was accomplished as a literature study of the river Nile, which is extremely important for water supply. The purpose of this study was to investigate the consequences of the construction of the Aswan High Dam, to obtain a consistent flow for water supply, irrigation and power generation in Egypt. Since Egypt has a very hot and dry climate large amounts of water in reservoir is lost to the Nubian aquifer system and by evaporation. The consequences from constructing the dam are considerable.
Elektronisk motorstyrning för ottomotorer
The combustion engines in today?s vehicles are getting more and more advanced and there are increasing demands on that the engines should operate during optimal conditions. Examples of internal combustion engine parameters which may be carefully controlled are the rate between fuel and air, that this gas mixture is homogenous enough and that it is ignited at the correct moment. Moreover, the requirements of these parameters vary depending on, among other, engine speed and load. To meet these requirements in all occurring operation conditions, it is required that many subsystems work together.
Geotermi i Ungern : Undersökning av Ungerns energisituation inriktat på geotermi samt kapacitetsfaktorn för det största geotermiska värmeverket i Mellaneuropa.
Hungary?s share of renewable energy in 2010 was 7.9 %, and their renewable energy goal for 2020 is 14.65 %. Geothermal energy is one option that could help to achieve the goal, since Hungary has favorable bedrock, the temperature gradient is above average and thepermeability is high. Today Hungary is importing just over half of its primary energy supply. Because of political conflicts between nations Hungary wants to expand its own production of energy.
Frivilligt utbränd : En undersökning av arbetsmiljön för heltidare på Uppsalas studentnationer
Den här uppsatsen syftar till att undersöka de psykosociala påfrestningar som heltidsengagerade på studentnationer i Uppsala upplever i sitt arbete. Genom en kvalitativ datainsamling under sammanlagt åtta intervjuer med "heltidare" har deras arbetsmiljö kartlagts med fokus på arbetsmoment som de själva upplever som stressande eller påfrestande.Analysen har sedan skett med bakgrund av tre stressmodeller: krav-/kontroll, effort-/reward och allostatic load. Med stöd av tidigare forskning av Maslach & Leiter, Asplund och Thulin Skantze. Detta har givit en bred och heltäckande uppfattning av hur de psykosociala påfrestningarna påverkar respondenternas utifrån deras egna upplevelser av sin arbetsmiljö.Av de framkomna och analyserade resultaten har flera slutsatser uppkommit. Framför allt kan man konstatera att heltidare har ett i längden ohållbart tungt arbete sett till arbetstiderna.
Uppvärmning och miljöpåverkan : -en jämförelse mellan fjärrvärme och bergvärme i villa
Many of todays studies show that district heating is one of the betteralternatives as heating source because of its low environmental load.The energy source is often leftovers from other processes producing energy or waste, like garbage or chips.Electricity in combination with geothermal heating is another heating system that has increased sharply during the last years, and also this system decreases the discharges that have negative affectson the environment compared to several other heating methods.This report aims to, concentrated towards these two different heating systems, estimate the amounts of discharges they indirect cause and how the environment is affected.We have calculated the mean value for discharges of carbon dioxide, nitrogen oxide, sulphur oxide and dust generated from electrical power used in Sweden.Through interviews and research we have gained data for the same substances that district heating based on combustion of garbage and biofuel generates.We have also in cooperation with a housing company chosen a building we see representative for many of the new single-family houses built in Sweden today.Based on its shape and appearance we theoretically created three alternatives of the same house, each of them with climate screens different from each other.Together with the amounts of discharged environmental affecting substances, these houses were the base for our calculations and studies when investigating the different heating sources environmental effect.The results have thereafter been analyzed and discussed from different angles..
KONTROLLBERÄKNING AV ETT TAKRAS PÅ EN TENNISHALL I NYKÖPING : En jämförelse mellan Eurokod och BKR
?Boverket? the Design Regulations in Sweden, also called BKR has for a long timebeen the mandatory standard that has guided and regulated construction design. Butat the end of 2010 BKR was replaced with Eurocode. This report deals with thecomparison of these two standards when it comes to wood construction. Duringwinter 2009/2010 there were many roof collapses due to excessive loads on theroofs across Sweden.
ETL-processen : teori kontra praktik
AbstractNowadays, companies and organizations manage large amounts of data to be used as support in decision making. A good solution for data management is in the form of data warehouses. A data warehouse is used to gather information from multiple sources within a company and arrange the information in a way that makes it easy to retrieve and analyze. Designing a data warehouse is not a simple task. The study herein will focus on what a data warehouse is and how the ETL process is used for data storage in the data warehouse. ETL stands for Extract, Transform and Load and is the process that retrieves data, transforms it and finally loads it into the data warehouse.
Jakten på vårdplatser som inte finns : En kvalitativ intervjustudie
Bakgrund: Vårdplatserna på svenska sjukhus har minskat drastiskt det senaste decenniet. Detta har inneburit en högre beläggning på de kvarvarande och medfört längre väntetid på landets akutmottagningar. Platsbristen skapar, ibland dagliga, överbeläggningar och utlokaliseringar av patienter.Syfte: Att undersöka hur sjuksköterskor och läkare upplever att vårdplatssituationen påverkar deras arbete och vad detta får för konsekvenser för patienterna.Metod: Kvalitativ design med semistrukturerade intervjuer med tre läkare och nio sjuksköterskor från akutvårdsavdelning med inriktning infektion, mottagning med akutintag och akutmottagning. Analysarbetet genomfördes med Malteruds (2009) innehållsanalys. Resultat: Vårdplatssituationen kommer sig av en brist på vårdplatser inom främst medicindivisionen, samt en oförmåga att hålla de platser som finns öppna på grund av sjuksköterskebrist. Bristen på vårdplatser har inneburit en oförmåga för läkare och sjuksköterskor att utföra sitt arbete i enlighet med sin kompetens och beprövad erfarenhet.Slutsats: Svårigheterna med att finna platser till patienterna på deras hemavdelningar samt de ständiga omflyttningarna av patienter medför svårigheter för vårdpersonalen att ge god medicinsk vård och omvårdnad vilket medför stora risker för patientsäkerheten.
Utmattning av järnvägsbroar i armerad betong : Enligt eurokoder
Commissioned for this report is Ramboll, Bridge and Tunnel Unit in Stockholm. Theidea throughout the work has been to primarily help bridge designers compilingadvice and instructions on how fatigue verification for railway bridges in reinforcedconcrete shall be performed under the new rules, the Eurocodes.After the introduction of the Eurocodes in 2011 has major problems emerged amongdesigners around Sweden. In some areas, it differs in the calculation rules comparedwith rules from the Swedish Transport Administration and the National Board ofHousing, Building and Planning calculation. Fatigue verification is one area where thenew calculation rules are different from the past.A large part of the report has been to interpret and find the relevant information inthe Eurocodes concerning fatigue. When questions or doubts have surfaced, this hasbeen discussed with Elisabeth Helsing at the Swedish Transport Administration andbridge designers at Ramboll.The result is a report where the structure is organized in the way that the bridgedesigners can move from cover to cover and realize that fatigue verification in realityfollows the same order as the report's sections.
Elektromagnetisk och mekanisk design av en 20MW turbogenerator
At the Division of Electricity at UppsalaUniversitythere are ongoing researches, including a research concerning turbo generators.Turbo generators produce a large share of electricity in the world; however they are costly mainly due to the fact that the cooling and ventilation that are needed to eliminate the excess heat from the generators are expensive. Turbo generators work with high efficiency and in this project, the main task is to simulate a generator while taking into account that the generator must be designed against self-oscillation, centrifugal force, exhaustion and heat. The turbo generator must be simulated without being too expensive and complicated.In this project, the dimensions of the turbo generator depend on the efficiency of it, and where the losses are in the generator. Furthermore, the optimum values need to be chosen with the help of the ACE simulation program. The report begins with an introduction describing the project followed by a task description that is dealing with the project.
Databaser i molnet : En prestanda utvärdering
AbstractAs a developer of database-driven applications you will be faced with difficult choices, when it comes to choosing database, server and programming language. For the result to be satisfactory it requires the different techniques to interact well with each other and also fulfill performance expectations. This is even more important when the application is deployed to the cloud and the response time plays a major role.This paper evaluates different databases and their performance. To test the databases there was an application made in the server script language PHP or Hypertext Preprocessor and it was deployed to Windows Azure cloud platform. The test applications task is to call and load databases by controlled requests which creates, reads, updates and deletes data in an relatively large extent.The results shows that locale databases or databases in the same data center as the server generates the fastest response.
