??Auktorisation och ackreditering inom Försvarsmakten : En studie i nyttan av en standardiserad process för att hantera informationssäkerhet
???Information Technology is an essential part of the society today, not least in large ???organisations dealing with sensitive information. An example of such an organisation is the Swedish Armed Forces which indeed is in the need of ways to ensure information security in their Information Technology systems. The means which is used is an authorisation and accreditation process.All Information Technology systems go through a life cycle which includes realisation, usage, development and liquidation. In the Swedish Armed Forces the lifecycle is an authorisation process.
Kunskapsbedömning i historia på gymnasienivå : En analys av fyra skolors bedömningsunderlag
As technology have continued to develop over the latest decades and become more advanced the pressure on the general citizens understanding of technology becomes a essential part to live in our society today. The transition have affected our society in great ways and have made a great impact on different groups, one of them being the elderly population in our society. The purpose of this study is to examine how the fast technological development in the latest decades have affected the elderly in our society. This from their perspective by gathering empirical data through semi-structured interviews with elderly people involved in the Agnes-project, a research project focused on improving the general quality of life for older people and increase their knowledge about technology. The study has shown that after the older peoples time involved in the Agnes-project their quality of life had improved in different areas. Areas such as increased cognitive activity, increased interest in new technology and an improvement in their communication with friends and family.
Skadeanalys och omkonstruktion av HMS Belos A-ram
In order to rescue a distressed submarine crew, the Swedish Navy is able to use a deep submergence rescue vehicle, DSRV. This mini submarine ascends, docks to the downed submarine and picks up the whole crew. The submarine rescue ship HMS Belos has a special crane located in the aft of the ship to lift the surfaced DSRV aboard, which then docks on to the on board pressure chambers located below deck. During inspections the aforementioned crane has shown to have problems with cracks in the structure, most of them located in the bolted joint between the top part of the crane and the two leg parts. A simulation of the forces acting on the structure in heavy sea condition was conducted; these values were then used as input values in a Finite Element Method, FEM, analysis of the joint.
?Men snöbollarna är ju mer än tio!? : en vetenskaplig essä om matematik, lek och lärande i förskolan
My aim with the experience-based essay is that I want to explore the implications of mathematics on children's development. I also want to examine my approach in relation to the various mathematical tasks. Why do we think that mathematics is important for pre-school children? What does the research say about how the teacher is thinking about mathematics? Can the teacher combine playing and learning and create meaningful moments and activities related to mathematics? I also want to explore our policies and the objectives that the teacher should relate to. What is required of me as a teacher in order to meet those goals?My essay is about mine and my boss?s view of the mathematical tasks that I usually perform in the preschool.
Bara för att? : En kvalitativ studie om hur studenter tolkar bilder i en publik kampanj om alkohol
En kvalitativ studie har genomförts på tre kampanjbilder från IQ-initiativets satsning ?IQ student?. Kampanjbilderna har ett motsvarande tema baserat på att det alltid finns en anledning till att dricka alkohol. Studien har med hjälp av fokusgruppsintervjuer och en intervju med IQ tagit reda på hur IQ vill att studenterna ska tolka bilderna och hur studenterna faktiskt tolkar dem. Studien utgick från teorier som receptionsstudie, semiotik och socialpsykologi.
Vad styr förekomsten av sälg och asp? : en studie av olika beståndstyper inom Hamra kronopark, Dalarna
Aspen (Populus tremula L.) and goat willow (Salix caprea L.) are two important tree species in the aspect of nature conservation. Due to the elimination of forest fires, a former negative attitude towards deciduous trees in forestry and a strong herbivore pressure, these tree species have been negatively affected during the last fifty years. The aim of this study was to investigate whether the occurrence of aspen and goat willow could be related to either human impact or to site properties, such as ground moisture and vegetation type. A side study included an inventory of a number of cyanobacterial tree lichens on aspen and goat willow in order to try to relate the occurrence of these lichens species to stand history and stand properties.
The study was performed in Hamra State Forest in northern Dalarna. Nature reserves were compared with stands in managed areas.
Sample cradle prevents pre-analytic error on platelet counts but is not essential for hemoglobin measurement and prothrombin time
Introduction: It is recommended to place all the vacuum tubes directly on a sample cradle after vein puncture to prevent analytic error. This recommendation is not always easy to follow because the samples are taken by different professionals under different situations. The three most common analyses, platelets count, haemoglobin and prothrombin time were tested. Therefore, it was interesting to compare results from the three most common analyses with or without sample cradle, to evaluate the influence of this step on the result. Methods: Three analyses were preformed, using blood from 50 different persons. Each person gave two vacuum tubes, each contained 4.5mL of venous blood for the study.
Har det svenska statsskicket Europeiserats? : Konstitutionella förändringar sedan EU-inträdet
Since Sweden became a member of the European Union (EU) several constitutional reforms has been taking place. During this time, Sweden has also changed its view on democracy,from a collective to an individual perspective of democracy in the politics. A reasonable hypothesis and the purpose of this essay is to investigate if the Swedish government has beendeveloped towards an Europeanization.The Swedish state audit changed in a pioneering way after the EU- entry, with the formation of Riksrevisionen. Another constitutional change is that the Swedish EU- membership is being instituted in the Swedish constitution. The role of Swedish courts has also changed since the EU- entry.
Evaluation of an automated multiplex real-time RT-PCR assay for rapid detection of Influenza A and B viruses
Influenza is a viral infection that affects global health and economy with its endemic and sometimes pandemic spread. Rapid detection of Influenza viruses enables antiviral use and can bring financial savings. It is also essential for the global surveillance of prevalent Influenza strains. RT-PCR is considered the most specific and sensitive method for detection of Influenza, but Influenza mutates at a high rate and it is therefore crucial that RT-PCR methods are updated regularly.In 2014, Cepheid released their Xpert Flu/RSV XC assay, which can detect Influenza A and B and RSV by multiplex RT-PCR in approximately one hour. The aim of this study was to evaluate this assay at Laboratoriemedicin Västernorrland by using the laboratory?s previous PCR assay for detection of Influenza viruses as reference method.Real-time RT-PCR was used to compare Xpert Flu/RSV XC to the reference method.
Glokala kampanjer mot fattigdom : Kommunikationsstrategier bakom statliga Världens Chans och ideella Utrota Fattigdomen Nu
Purpose/Aim: The purpose is to describe, analyze and compare the two communication campaigns Världens Chans and Utrota Fattigdomen Nu, and discuss how and to what extent communication campaigns in Sweden can be used to reduce global poverty. The theoretical framework is mainly based on communications strategies and other relevant aspects of the planning process of campaigns.Material/Method: Within the qualitative case study as an overall method, the main material to the two cases is obtained through five qualitative interviews with the premier representatives of the campaigns.Main results: Världens Chans can be seen as an information campaign by the government which purpose is to contribute to the fulfilment of the millennium goals by drawing the attention of the public to their existence. Utrota Fattigdomen Nu, on the other hand, is an influence campaign by the civil society which purpose is to exterminate poverty by putting a pressure on power holders and to change the attitudes and the behaviours among the public. Both campaigns are based on a network with lots of different actors, functioning as opinion makers. Furthermore, communication campaigns are important tools in the fight against poverty..
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.
Elektronisk Handel : Framtagning av två implementeringsmodeller
This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.
Potential för energiklippdrivare i Skåne : markägarintresse, råvarutillgång & ekonomi
As the Swedish governments long term goals include a reduction of fossil fuel dependency,
increasing pressure is placed upon energy companies to create and develop new solutions for renewable energy. The following case study was done in collaboration with the company
Sydved Energileveranser AB and one of their contractors, Enarssons Skogsentreprenad AB.
The objective of the study is to examine the bioenergy situation in region of Skåne and
evaluate the potential solutions in the region for a forest-fuel assortment, based on a bioenergy-cutting-system. As a part of this study I have compared ordinary manual cuttings done with a chain saw and cuttings made using the new ?bio- energy cutting system?. The cuttings made under both systems were tested in areas near agricultural fields or pasture land in order to maintain an open landscape.
Prion infection of ovine cell culture with a natural Swedish scrapie isolate from 1986
Scrapie is an infectious neurologic disease in sheep caused by prions, corresponding to transmissible spongiform encephalopathies (TSEs) in other species. The prion is presumably constituted of PrPSc, the misfolded form of the normal endogenous prion protein, PrPC, which is found in practically all cells in the body. PrPSc can induce a conformational change in PrPC and misfold it as an imprint of itself; this is how prions amplify and spread. The process of conformational change is poorly understood and there might exist intermediate forms between PrPC and PrPSc. Bioassay using mice has traditionally been the golden standard in prion studies but is limited by cost and time.
Biomass losses during short-term storage of bark and recovered wood
Storage of biomass is associated with problems like heat development, biomasslosses, and reduction of the fuel quality. Certain processes such as biological- andchemical degradation are responsible for these storage problems. This master?sthesis was carried out at Vattenfall Research and Development AB and is alignedtowards quantifying the biomass losses from short-term storage (1-2 months) ofbark and recovered wood. The biomass was stored in outdoor piles during differentseasons, campaign 1 (summer) and campaign 2 (autumn).
