Jämförelser av olika former av QRA och andra metoder för riskanalys av processindustrier

When performing a QRA you have to consider a number of accident scenarios. How many scenarios you choose often determines the time and resources needed to perform the QRA. The report investigates the possibility that a QRA can be performed using only a few representative scenarios. Further it presents a discussion on how these scenarios should be constructed..

Byggsäkerhet ? gällande lagar och föreskrifter samt vanliga överträdelser

Järntorget bygg AB arbetar med nyproduktion av framförallt bostäder. Liksom alla andra arbetsplatser i Sverige berörs en byggarbetsplats av Arbetsmiljölagen med dess förordning och författningar. I dessa paragrafer som alla finns för att göra arbetsmiljön så säker som möjligt finns krav på att en Arbetsmiljöplan skall upprättas, vilket är den individuella strategi som tillämpas på varje byggarbetsplats för att uppnå god arbetsmiljö. Dessutom finns på byggarbetsplatser ett ordnings- och skyddsreglerdokument vilket är det dokument som varje ny hantverkare skall ta del av vid ankomst för att känna till arbetsplatsen bestämmelser.  Genom att ta del av gamla skyddsrondsprotokoll, delta på skyddsronder och genomföra intervjuer på Järntorgets i dagsläget tre aktuella byggarbetsplatser kan det konstateras att överträdelser mot såväl Arbetsmiljölagen som mot den egna Arbetsmiljöplanen och ordnings- och skyddsregler sker.

Termomekanisk utmattning av Sanicro 25 : Materialmodellering med finita elementmetoden

The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal ? and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well.

Säker hantering av lösgående nötkreatur :

After I heard that two deadly accidents in farming 2003 were created by work with cattle, I got the idea of writing this degree project. So far there are not too many reports written about safety for the worker nor the animal. Therefore it will fit in with a report about safe handling of free stalled cattle. The Swedish Board of Agriculture would also like to do an information material about outside stalled cattle with this degree project as a background. The collecting of material was made by visiting farmers. The goal was to visit 15 ? 20 herds and when this is being written 19 herds have been visited.

Emerging zoonotic viruses : what characterizes them and what are the risk factors for their emergence?

Emerging infectious diseases poses a great future threat, not only to humans but also to domestic animals and wildlife. Even though the majority of these infections only cause minor health problems, the relatively recent emergence of HIV clearly illustrates that the next major human pandemic may surface at any time. Regardless of what the name indicates, most emerging human pathogens are not believed to be recently evolved, but to have existed previously in the natural environment. Most emerging pathogens are zoonotic, i.e. able to infect animals besides humans.

Den gyllene medelvägen: en diskussion kring unga invandrares erfarenheter av mötet mellan ursprunglig och svensk kultur och hur detta har påverkat valet av identitet

The purpose of this study was to discuss young immigrant's experiences of the meeting between their original culture and swedish culture. In this discussion certain emphasis is laid on the formation of identity. In a more specific manner the aim was to find out which underlying circumstances contributed to the individuals choice in considering him- or herself as swedish or not and what these circumstances depended on.The empirical material of this study consists of five lifestories based on the methodological study of narrative. I have analyzed the material with help from Anthony Giddens' theory of structuration with starting point in the conception of ontological safety. I identified four different themes that frequently recured in each lifestory: identity in migration- and integrationsprocesses, the open doors of globalization, "swedish" identity and belonging in two cultures.

Kartering av markföroreningar inom Skutskärs Bruk samt utvärdering av spridningsrisker enligt Naturvårdsverkets MIFO fas 2

With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.

Varierande Vägar till Frihet - Hur staten och civilsamhället interagerar för demokrati i Vitryssland, Moldavien och Ukraina

The three post-communist states - Belarus, Moldova, and Ukraine ? have gone different ways in terms of freedom and democracy since the breakdown of the Soviet Union 1991. During these years, the state and the civil society have been fundamental actors in the struggle against, and even for, authoritarianism.A strong state with great capacity in Belarus has undermined the chances for the civil society to fulfil its task as a watchdog of the state and link between the citizens and the government.Failed authoritarianism in Moldova has led to a situation where both the state and the civil society are weak. The major problem is lack of organization and cohesion; both the state and the civil society have often been divided by ethnical differences and are therefore not strong enough to promote democracy.In Ukraine, the dominance of a strong state ended in 2004 when the Orange Revolution took place, sometimes called a ?peak of democracy? where popular mobilization and protests succeeded in it's opposition against the state.

Det antropocentriskt styrda Sverige : En undersökning om riksdagspartiernas miljöideologiska närings-, miljö- och jordbrukspolitik under mandatperioden 2002-2006

This essay examines the environmental ideological direction of the Swedish parliamentary parties through the private members motions directed to the committee of industry and trade and the committee of environment and agriculture during the governmental time from 2002 to 2006.The environmental ideologies explained is anthropocentrism, ecocentrism and biocentrism. Based on the ideas of these three ideologies main points the private members motions directed to the committee of industry and trade and the committee of environment and agriculture, also matching the search words environment and energy, was compared and analysed.What has emerged is that all parliamentary parties express a desire to create an energy production and producing guide lines which are stringent environmentally and matches the safety requirements. Although the approach to environmental and safety standards differ significantly between them. Basically all Swedish parliamentary parties are more or less anthropocentric in its arguments, which in short terms means that they estimate natures and animals value through their usability for humans or based on their contribution to human feelings of wellbeing.The Centre Party and the Green Party shows hints of weak ecocentrism because in many cases they put animal intrinsic value high, but the human value higher. Moderates are predominantly anthropocentric but they also express some hint of biocentrism in one statement concerning research in order to reduce and rebuild environmentally destroyed areas.

Dammsäkerhetsutvärdering samt utformning av dammregister och felrapporteringssystem för svenska gruvdammar

A lot of mine waste rock and tailings arise from all mining processes and have to be stored in an appropriate way. Tailings are deposited in impoundments retained by tailings dams. The objective of tailings dams is to retain the slurry from the mining process and in that way prevent spill into the surroundings that might be harmful for the environment. Tailings dams are often constructed as staged embankments so that construction costs and demand of materials are spread more evenly over the period of deposition.The objective of this thesis has been to compile information about and evaluate events at Swedish tailings dams and also to develop a collective database for all Swedish mining companies for all tailings dams and all events that occur at tailings dams.Information about 60 events at Swedish tailings dams has been gathered and evaluated. The evaluation has been performed by comparison between and analysis of individual parameters and also by use of a multivariate statistical method called PLS.

Varbergs goda jord : en fallstudie om värdering och förvaltning av åkermark i Varbergs kommun

This is a bachelor thesis about arable land in Varberg, from sustainability and it?s relation to local government and management. Arable land has become more important as a natural resource from a global point of view and in concerns of higher demands of food supply, as a result of population growth, higher consumption worldwide and climate change. But the arable land in Sweden is being exploited an increasingly rapid pace and the arable land in Varberg is not an exception of this development. The issue is most topical and the discussion holds questions about a declining agricultural sector, the formal and administrative protection of arable land and because other interests of land use often is given higher priority in community development and planning.

Sjuksköterskors uppfattning av elektronisk dokumentation avseende tidsåtgång, teknik och vårdkvalitet

Documentation in electronic journals is perceived as time consuming and sometimes technically difficult to handle, but also leads to an improved quality of care. Objective: The purpose of this study was to investigate nurses' perceptions of documentation with a focus on timing, technique and quality of care and whether any differences in these perceptions were dependent on age. Method: Quantitative descriptive cross-sectional study in the survey form, 28 nurses at a university hospital in central Sweden participated in the study. Regression analysis was performed with Spearman's rank correlation coefficient. Results: Electronic documentation takes 30 to 60 minutes for most nurses and half of them considered it a reasonable time.

En teori om konsumentmakt- Marknaden som en lösning på demokratiunderskottet?

How effective is consumer power? Can consumers regulate corporate behavior?And if so is the case, could the mechanisms where consumers regulate corporatebehavior have any democratic value to contribute with? These are the questionsthat this master's thesis comprehends with. The purpose of this writing is toconstruct a theory of consumer power that is compatible with democratic theory,this in order to contribute to the ongoing discussion within the discipline ofpolitical science about the third democratic transformation. A discussion that hasbeen actualized due to the democratic deficit created by the growing corporatepower and the shift of power from state to private enterprises. Besides showingfor a parallel between the democratic mechanisms that exists in the relationbetween citizens and state on the one hand, and the consumers and corporationson the other hand, this paper argues that consumers do have a great potential inregulating corporate behavior towards a higher social responsibility andawareness.

Hit men inte längre? : En studie av Mocambiques demokratisering

Följande studie undersöker i vilken utsträckning parterna i trepartsförhållandet Upsala Nya Tidning, annonsör och läsare har överensstämmande åsikter om vad som är viktigt i relationen, samt hur väl de känner till varandras uppfattningar. Vi väljer att studera förhållandet ur ett trepartsperspektiv då de mer traditionella tvåpartsförhållandena inte är tillräckliga för att beskriva den komplexa verkligheten. Studien utgår från UNT:s printupplaga, men skildrar även skillnader mellan den och webbupplagan. Ett representativt urval av varje part tillfrågades via en enkätundersökning vad de själva tycker är viktigt och vad de uppfattar är viktigt för övriga parter. Resultatet visar på att parterna inte har överensstämmande åsikter om vad som är betydelsefullt i relationen.

A proactive health, safety & environment risk management strategy : what are the incentives?

In a business environment where the stakeholder perspective is evolving and sustainable development is receiving increased attention, it is of importance for companies to adjust. The demand and pressure is exerted from several stakeholders who force companies to take action and live up to the expectations because if failing to do so, negative consequences will most likely be the case. The attention of this study is on ABB Power Products (ABB PP) and their environment and working environment risk management. The aim of this thesis is to identify and describe how perceived environmental risks are managed and what the incentives are to work proactively to minimize the risks. The incentives for a proactive risk management strategy are researched through both a strategic and operational perspective.
