Påverkan på elektronik och sensorer i radiologisk miljö

The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..

Genomförande av e-handelsdirektivet i svensk rätt

Along with the development of technology, the cross-border trade is increasing and therefore there is a need for greater consumer protection. A good consumer protection creates a feeling of safety for the consumer and that by itself may help to increase cross-border trade. This is one of the reasons for why the EU has established regulatory framework for electronic commerce, for example the Directive2000/31/EC. The direc-tive strives to create a similar law for electronic commerce within the European Union. This paper?s main purpose is to ensure that the directive is implemented properly in Swedish law, and if there are other possible ways to achieve the objective, other than the ones that the Swedish legislator has chosen.

Säkerhetsklimatet inom Norrbottens läns landsting

Syftet med detta examensarbete var att skapa en lägesbild över säkerhetsklimatet inom Norrbottens läns landsting och ge information om vilka eventuella insatser som skulle behöva genomföras för att skapa ett gott säkerhetsklimat. De frågeställningar som skulle besvaras i anknytning till syftet var: Hur är det allmänna säkerhetsklimatet inom Norrbottens läns landsting? Hur uppfattar de anställda att ledningen förhåller sig till säkerhet inom Norrbottens läns landsting? Hur uppfattar de anställda att den arbetsgrupp de tillhör förhåller sig till säkerhet inom Norrbottens läns landsting? Är det någon skillnad gällande uppfattningen av säkerhetsarbetet inom Norrbottens läns landsting mellan chefer och medarbetare? Studien innefattade en enkätundersökning med 127 anställda och enkätinstrumentet som användes var Nordic Safety Climate Questionnaire (NOSACQ-50). Resultaten indikerar att säkerhetsklimatnivån var relativt hög inom Norrbottens läns landsting. Säkerheten prioriterades av chefer likväl som av medarbetare.

BRISTER I MÄRKNING AV LIVSMEDEL? HUR PÅVERKAR DET OSS?

An organisation in Skåne, Miljösamverkan Skåne, presented a project in 2011 concerning food labeling. All municipalities in Skåne, audited certain products in several stores, in order to determine if they were labeled correctly according to law. Stores who produced their own food where also audited. As Swedes generally have an interest in buying and cooking food from different countries, the demand is increasing, which makes stores provide the customers with a large range of different products to accommodate the demand. This essay will discuss the results of the project and how incorrect food labeling can affect human health.

Continuing Airworthiness Management Exposition : For Priority Aero Maintenance

The economic crisis has affected the airline industry as much as it has affected all other industries in the world. The small airlines and maintenance organisations must find new opportunities and options in order to survive the harsh crisis. Priority Aero Maintenance is now an approved maintenance organisation performing maintenance on aircrafts, engines and components. The company sees economic gains in the future by becoming an approved organisation that follows the European Aviation Safety Agency guidelines (EASA) and meets the requirements outlined in the rules of Part-M.In order for the company to become an approved organization, responsible for continuing airworthiness of aircraft, a handbook should be presented to the local authority. This handbook describes the company?s responsibility for the continuing airworthiness in order for the authorities to get an insight into the company and its work.This thesis resulted in a draft of CAME (Continuing Airworthiness Management Exposition) and this draft has been approved by Priority Aero Maintenance.The CAME will in the future be used by the company as a basis for developing a more detailed manual to be presented to and approved by the Swedish Aviation Authority (Transportstyrelsen)..

?Social media is word of mouth on crack? ? En studie i hur detaljhandelsföretag kan öka sin internettrafik via sociala medier

Den här studien behandlar fenomenet sociala medier med inriktning på att öka trafik till detaljhandelns webbaserade sidor för att skapa relationer, bygga varumärke och öka försäljning.Idag står företag inför en ny utmaning när det gäller marknadsföring. På några få år har internethandeln exploderat och med det företagens sätt att marknadsföra sig virtuellt. Sedan början av 2000-talet har en ny kanal för att sända ut marknadsföringsmässiga budskap till kunderna uppstått, de sociala medierna. Ett exempel på en av dessa är Facebook vars användarantal bara stiger år för år och i dagsläget har fler än 6 av 10 svenskar en personprofil på Facebook.Varje kanal för kommunikation har sina egenskaper och med det givna referensramar för företagen att arbeta med och skapa verktyg för. Då sociala medier fortfarande är ett ganska nytt fenomen anser vi att problematiken ligger i att många företag inte har hittat det ultimata användningssättet för kanalen.

Persontäthet vid utrymningsberäkningar : Köpcentrums persontätheter

The aim of this study is to evaluate whether the value of occupant load is over or under estimated when the Swedish general value for department stores, 0,5 person/m2, is used for dimensioning shopping centers. The data that was analyzed derives from seven shopping centers and one department store. A conservative method was used to calculate the occupant load factor. The analysis shows that two groups can be discerned: one group that is characterized by a lower occupant load factor that does not exceed 0,3 person/m2, and one group with a higher occupant load factor. Shopping centers with a higher occupant load factor are located centrally in large urban areas.
