Fichtelius-affären och public service-ideologin
With this master thesis I wanted to find out whether Erik Fichtelius, an SVT employee, interview project with prime minister Göran Persson is acceptable according to the public service ideology. In order to do that I used Swedish newspaper articles to analyse the so called Fichtelius affair. I also gathered material on SVT and the public service ideology. The master thesis is based on sociologist Manuel Castells theories on mass media and television as presented in the Information Age. Castells claims that in our time different areas, such as politics and television, are melting together.
Komplikationer vid behandling med cochleaimplantat
Cochlear implant has become a common treatment for people with severe hearing loss. As the field of cochlear implants is developing rapidly a larger group of patients will be implanted. Therefore, it can be of interest to identify which complications are most frequently occurring. Objective: The aim of this study is to identify and present the most common complications in cochlear implant treatment and to identify surgical issues that have to be addressed during implantation. Method: A review of retrospective case studies regarding complications has been made.
Bland brons och järn - spåren av metallhantverk från Bornholms yngre järnålder.
This essay is about Late Iron Age settlement and its production. I want to define the nature ofthree different workplaces on Bornholm, Denmark, and compare them. My aim is to see if itis possible to define a workplace through the traces of the craftsmanship. Several materials areselected in this essay and the analysis provides different perspective on workplaces in the LateIron Age in Scandinavia. The results of the analysis between the three workplacesAgerbygård, Baggård and Kanonhøj shows that Baggård have more traces of melting of bronsthan any other of the places.
Demonstratortest av gassensor baserad på tryckt organisk elektronik och jonledande papper
Researchers at Karlstad University have developed a method for making paper ion conducting. The reasearchers want to test this technique in various applications and produce products that make use of the ion-conducting paper. Hopefully this will drive the development forward and result in new applications for the ion-conducting paper.This study was to test the possibility of manufacturing a gas sensor of conducting paper along with electrodes of conductive polymers printed on the paper. By comparing the paper sensor with an electrochemical cell in which the electrodes of conductive polymer replaces electrodes of metal and ion-conductive paper replaces the liquid electrolyte in the electrochemical cell, it was hoped that it would be possible to measure the oxidation and reduction reactions that a gas could introduce at the electrodes.It was shown that it is possible to measure a potential difference in the range of 0.3 V to 0.5 V between the electrodes when exposing an electrode to 100% oxygen. The reaction that takes place is relatively slow and the reaction rate is partly due to the distance between the electrodes.Since the sensor can measure oxidation and reduction reactions it is possible that, in further development of a sensor, the sensor can be made ??into a versatile sensor with more applications than gas measurement as there are many more ways to oxidize or reduce the electrodes than by exposure to oxygen.During the study there have been discussions and meetings held with various companies in the sensor industry to be able to specify what the market demands of a sensor made ??of paper and the requirements that must be placed on the sensor for it to be interesting for the companies..
Energiåtervinning från gjuteriprocess till fastighet, undersökning för ökat utnyttjande av spillvärme
This diploma work on D-level is made in cooperation with Varnäsföretagen AB in Eskilstuna. The company performs contract manufactured aluminium goods. This work is a continuation on earlier diploma work in Varnäsföretagen AB. Even if the industry process consumes much energy for melting the aluminium goods, they consume a great amount of oil to warm up the building. The purpose of this work is to examine some places in the building and the process to see how much energy it is possible to recycles to the heating system and reduce the costs for heating.
Sensory nerve conduction studies in young adults for the expansion of a reference material
Neurography is the most objective and reliable measure of the peripheral nerve function, and it is used to diagnose both local and generalized neuropathies. Neurography can measure both motor and sensory nerve functions. The principle for sensory neurgraphy is to stimulate over the nerve and record proximal or distal from the stimulated electrode.At the Department of Clinical Neurophysiology, University Hospital Uppsala, a problem has been identified, in that young adult patients tend to show unexpected abnormal neurography values in relation to the expected, indicated by the reference limits, without clinical correlates. This concerns foremost the sensory amplitudes in median and ulnar nerves. The hypothesis is that the requirement of young adults? amplitudes is too high.
Vart bör Kiribati, Tuvalu och Marshallöarnas befolkningar ta vägen? : En normativ analys inom ämnet för klimatförändringarnas utmaningar
The effects of anthropogenic climate change are becoming more and more visible as being highlighted by scientists, politicians and media. The causes of droughts, floods, melting ice caps and rising sea levels can all partially be traced back to human activities. In this study, I examine where the future climate refugees of Kiribati, Tuvalu and the Marshall Islands should go when inhabitants of these low lying island nations are forced to leave their disappearing territories due to sea level rise. By using a normative method of analysis i egentlig mening, arguments deriving from certain values will be presented to confront the problem. These values originate from Edward A.
Konsumtionens klimatpåverkan : En jämförande studie mellan två socioekonomiskt skilda bostadsområden, Araby och Söder i Växjö
The world is in a stage of climate crisis where the average temperature is rising, with consequences such as, melting ice sheets, increasing sea levels, and floods. The climate panel of the UN, IPCC, has stated that this is a reaction of anthropogenic emissions of greenhouse gases. The most important gas is carbon dioxide, which contributes with 80 per cent to the on going climate crisis.The increasing emissions of carbon dioxide are connected to human consumption patterns. This puts pressure on the earth, as humans demand more and more resources. Today the earth needs one and a half year to regenerate the resources humans? demand of it, by the year 2030 we will need two planets in order to cope with this increasing demand of resources.At a global level it is established that richer countries have a stronger consumption pattern than poorer, and thus generate higher levels of carbon dioxide emissions.
Dendroklimatologisk analys av lokalklimat vid Grövelsjön i Dalafjällen
Climate on earth is getting warmer, which effects earth?s energy balance and so forth the ocean and atmospheric circulation. In many sub-polar regions on the northern hemisphere changes due to warming of the climate can be observed. Some examples that already have been observed are shifts in tree line, towards higher altitudes and latitudes, increased ablation of Swedish glaciers and melting of the permafrost on the Siberian tundra. In Sweden climate change scenarios tell us that it will become warmer and that a higher amount of precipitation in form of rain will be an effect from this. To study climate changes in Sweden, transition zones are useful in order to observe changes in distribution of species and animal populations.
Bachelor thesis Re : bottle
There is a new beverage container on the market, a bottle made out of pure aluminum as a replacement for the traditional container made out of glass. This new container has the potential to reduce both cost and pollution during transportation, the lighter and stronger construction has every advantage compared to the old one in glass. The new container has every possibility to make it on the market. Some of the biggest brands within the soft drink market already use these bottles in countries without any recycling demands like: Coca-Cola, Heineken and Pepsi. The only thing stopping these brands from the Swedish market is the lack of a functional return system, there is only one company that uses the bottle in Sweden today and they take care of their own used bottles.
Matregionen Södra Roslagen : en etnologisk studie om lokala beskrivningar av en regions mat
North of the city of Stockholm lies the area called Södra Roslagen composed of several municipalities. The purpose of this essay is to discover how local informants describe the food culture of the region and analyse why some types of food are mentioned and others are excluded. Several people within the food industry of Södra Roslagen were given surveys asking them to describe the food habits of the area, from commodities and certain dishes to traditions. These answers were analysed using the theories regional food, regiocentrism, revitalisation, placeless food and the idea of viewing culture through the long and the short perspective.One informant mentioned that professionals in the food industry of the region tend to follow trends from the rest of the world and another that many producers work with ecological requirements. Södra Roslagen was also defined by some as having a taste of summer as this coastal area sees an influx of visitors during that season.
Historiska emissioner av bly och arsenik till luft från Åfors Glasbruk och deras konsekvenser för miljön.
Åfors glasswork was a company which started in 1876 and closed in 2012 due to the bad economical situation in the company. After its closure, the glasswork left behind contaminated soil with different concentrations of heavy metals such as, arsenic from arsenic trioxide, a chemical used to remove bubbles during the melting of glass, and lead oxide, a chemical used in the production of crystal glass. Crystal glass?s production occurred under 1921-1971, but emissions of lead into the air from Åfors glasswork continued until 2011, because of the artist Bertil Valliens? artglas was made in Åfors glasswork from 1970?s and onwards.The aim of this study was to estimate how much lead (Pb) and arsenic (As) that were released by Åfors Glasswork into the atmosphere during the operational period of the glasswork in comparison with how much of lead and arsenic were purchased for the company. Added to the assistance of the data from National Archives the variations in the activities of Åfors glasswork could be shown.
The effect of vegetable fat on cheese yield and cheese properties
The production of cheese is in continuous development with objectives to in-crease productivity, achieve changes in shelf life and functional properties of the products. One concept in the development is to substitute milk fat with vegetable fats and oils in the manufacture of cheese.
The objective of this study was to investigate effects on cheese yield and cheese quality of 4 different semi-hard analogue cheese products produced by substituting milk fat with vegetable fat, each analogue cheese with a specific mixture of vegeta-ble fat. As reference a cheese produced with anhydrous milk fat was used.
The yield and recovery of fat and protein were determined by recording the weights of each cheese direct after press and after 20±2 days of storage and analysis of the composition of the cheeses after 20±2 days of storage. The cheese was fur-ther subjected for texture profile analysis in a TA-XT Plus Texture Analyser and analysed with Differential Scanning Calorimetry (DSC) to examine whether the fat behaves similar in the cheese as in pure form in respect to its thermal properties.
The cheese yield was not significantly different when using different fats. Differ-ent amounts of water were absorbed during the water cooling.
Biogasproduktion genom tvåstegsrötning av drankvatten
During the 19-century a global warming has been observed, which includes increases in global air and ocean temperatures, widespread melting of ice and snow, and rising global sea level. There is a clear connection between emissions of greenhouse gases caused by the human and the increase in temperature. Climatic changes caused by global warming can be stopped trough decreased emission of fossil fuels, for example by an increased use of biogas. Biogas is a renewable energy source which is produced through anaerobic (oxygen free) digestion of organic material. The gas is a mixture of methane (CH4) and carbon dioxide (CO2) and can be among others used as fuel in vehicles.
Angelägna omvårdnadsaspekter för att skapa känsla av trygghet och säkerhet för patienten i samband med EKG registrering.
En viktig del i sjuksköterskans arbete är patient bemötandet. Patienten befinner sig i ett utsatt läge som i vissa fall är helt främmande för patienten. Ett förtroende till att omvårdnaden är säker och trygg måste kunna byggas upp. Patientens medverkan ger oftast en positiv utveckling av tillfrisknad och känns här viktig för patientens värdighet, integritet och självbestämmande.En av sjuksköterskans många uppgifter är att registrera en patients hjärtfrekvens via ett elektrokardiogram (EKG) på ordination i diagnostiskt syfte. En oro hos patienten, illabefinnande eller en nedsatt förmåga att medverka i EKG registrering kan påverka kvaliteten på ett EKG och kräver ett professionellt bemötande av sjuksköterskan.
