Flamskyddande kemikalier används idag inom en hel del olika områden. Ett stort område är textil, där hemtextil är dominerande. Det finns en mängd olika typer av flamskydd på marknaden. Alla har till uppgift att sakta ner brandförloppet eller helt förhindra att en brand uppstår. De halogenerade flamskydden är de mest effektiva men har många kopplingar till miljöproblem.

The purpose of this study is to survey and evaluate if the individual contrast sensitivity and preferences for horizontal and vertical lighting level correspond to the values that standard SS-EN 12464-1 recommends for the workplace- and surrounding light levels.This study examines if lighting should be adapted after the individuals? need or if a general value can be found that will cover every individuals? need for a workplace and surrounding light level. This study also examines if parameters like sex, age and/or glasses/lenses have an effect on the amount of lighting that the test subjects need. Lastly we compared the values concerning the relationship between workplace- and surrounding light levels with standard SS-EN 12464-1?s recommendations.The study is carried out with an experimental design that surveys 220 test subjects who were chosen by a selection of convenience.

The aim of this study was to investigate how the process of implementing a quality management system for food safety was handled in four different food producing companies in Sweden. The aim was also to analyze what difficulties the companies face and the possibilities that arise when certified. Furthermore, the reason for implementation was discussed as well as the main expectations on the certificate. Implementing a quality management system is a good way of ensuring the quality and hygiene of the food production and it also increases the traceability of food products through the whole food chain. A food safety standard provides a method of preventing problems and crisis and it can also help to handle requirements from authorities, the market and others.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

The tsunami in Thailand in 2004, 9/11 and hurricane Katrina in New Orleans 2005 are all reminders that no organization is immune to crises, which also means that all organizations should be prepared and know how to handle a crisis if one was to occur. A case study has been conducted, on a crisis regarding a fire that occurred on the 31st of July 2014 in Västmanland, Sweden. Through Qualitative interviews empirical data was gathered and then analyzed together with our theories and previous research. The purpose of the study is to analyze how the municipalities affected and the County Administrative Board of Sweden handled and communicated with/to the public during the fire that spread in Västmanland 2014. Our study shows that a risk analysis and analysis of surroundings is crucial in anticipating a crisis event and that it is essential for organizations to undergo training to prepare organization members on how to handle a crisis. Another conclusion is that the need for information is large during a crisis event and grows throughout the entire course of the crisis. The crisis that we studied had a lack of information, but at the same time the public?s need for information is a need that can?t be satisfied during a crisis.

For a company to get the best possible profitability, requires financial planning. Budgeting isa common tool in financial planning. For operating lamb producers, a planning program suchas Agriwise is a good tool. Individual lamb producers may change certain standard figureswithin the planning program to better correspond with reality of the individual cases. In thisway, lamb producers may plan according to which revenues and costs they may expect thenext period.

This report deals with the attitudes within municipalities of open source software and open standards and if open source software may be an option to gain open standards. The aim has been to find out if open source software and open standards would be able to solve the lock-in problems that municipalities have against proprietary software. The study is conducted as an exploratory, inductive and qualitative study with depth interviews of subjectively selected informants as data collection method. A literature review has also been implemented by the relevant books and articles. Some economic determinants of municipalities to make use of open source software have not been considered in this study.

The purpose of this study is to investigate the proposed leasing standard's potential effects on stakeholders' financial key ratios and estimated bankruptcy risk via prediction models based on accounting ratios. This is achieved by adjusting the financial statements in accordance with the three most widely used ways of dealing with operating leases at date; capitalizing using a multiple, capitalizing through a present value method and to not adjust for them at all. Since the discounted method is said to reflect the proposed standard the closest, this version will be compared against the two other versions. The research is based on Nordic retail companies due to their high share of leases. The study shows that the unadjusted key ratios and estimated bankruptcy risks tend to be too low and would therefore deteriorate in combination with the new standard, when again the multiple method results in too weak key ratios and high estimated bankruptcy risk and would therefore tend to improve in combination with the new standard.

The study shows the current need for security solutions concerning work with information in different areas.Investigations will show important solutions for printers? needs to meet the increasingly harder demands forfast and safe digital communications. Important factors to be analyzed in the investigations are: access todifferent types of information, workers authority of information, access to the data base register internallyand externally, production solutions for an effective fault detection and data base solutions fororders and distribution.Planned and unplanned stops result in a standard of value in interruptions. Internal data bases areprotected by so-called ?Fire Walls?, ?Watch Dogs? and Virtual Private Networks.

During a fire large amounts of particles and unhealthy agents occur.  Polyaromatic hydrocarbons (PAH) and toxic metals are examples among many others. These agents have a capacity to bond to particles and when the fire is extinguished, the particles can be transferred with the extinguish water into the soil and to the groundwater.Recent studies in particles have been conducted. A study by Ulrika Iverfelt (2014) reviled that the particles from a fire contained large amounts of both PAH and metals, which is consistent with earlier analyses. Her column experiments with particles in the size ? 11 microns and ?100 microns in silica sand, reviled that the larger particles was immobilized because the transportation was influenced by sieving or physiochemical particle and surface interactions.The transport of the particles in soil and groundwater is regulated by two main mechanisms: physiochemical surface interactions and straining.

What is located on the bottom in the water outside of Birka? Remains of a water palisade or jetties and other constructions.Birka a Viking Age town that existed between AD 750 and 975 was located on the northwestern part of the small island of Björkö, in the Mälar archipelago of the Baltic Sea in Sweden. The Town was protected onshore by a hill fort and a town rampart. It is a widely spread assumption that Birka had a water palisade as a part of its defense. There are logs and other remnants on the bottom of the lake dating back to the Viking age.

En samverkanspelare drar nytta av interaktionen mellan det omslutande stålröret och profilens betongkärna för att därav erhålla en ökad lastkapacitet. För att förstå beteendet och effekterna av interaktionen mellan stål och betong är det viktigt att förstå de enskilda materialens beteende. Betongens huvudsakliga uppgift i en samverkanspelare är att ta upp tryckkrafter medan stålets främsta uppgift är att motverka momentpåkänning och uppta dragkrafter. I normal rumstemperatur samverkar stål och betong för att bära den aktuella lasten.Samverkanspelaren har stor potential med avseende på lastkapacitet. Nedan tas några av de förväntade positiva effekterna av interaktionen mellan stål och betong upp:Förekomsten av buckling för stålet försenas samtidigt som den försämrade bärförmågan efter lokal buckling uppstått dämpas, beroende på betongkärnans återhållande effekt.Förhindrar spjälkning och hållfasthetsnedsättningen för betongen blir inte lika drastisk.Ökad tryckhållfasthet och deformations kapacitet, speciellt för grövre tvärsnitt.Vid ett brandscenario utsätts pelaren för en temperaturhöjning.

The ISO standard ISO/IEC 17799/SS-627799-2 is a guidance for organizations to realize their information security goals. In spite of this standard, studies show flaws regarding information security in organizations. In particular flaws regarding overall view, knowledge and clear roles and responsibilities have been observed. The ISIT (Information Security Integrated Three level) model and its guidelines, developed in this thesis, help organizations to identify the required processes and procedures as well as the logical process flow. The thesis is based on theoretical studies and a case study within a multinational company.

This bachelor thesis discusses firefighting and the use of portable fireextinguishers in the salvageof historic artefacts focusing on textiles. It also looks into the use of multi-purpose dry chemicalextinguishers in a textile context and the impact the actual dry-agent has on textiles afterfirefighting.Literature studies, interviews and tests on different textiles were carried out to write this thesis.During the tests textiles were exposed to the dry agent and also to dry agent plus water toinvestigate the difference in residue. After vacuumcleaning it was clear that when the textile wasexposed to dry agent and water it was almost impossible to remove the chemical without rinsingin water.By examining the residue left on the textile using SEM it was possible to see if a textile was aswell decontaminated after vacuum-cleaning as it looks to the eye. We know that the dry agentoften consists of ammonium phosphate which acts corrosively on many materials and one canassume it damages textiles as well after longer exposure.Buildings housing cultural collections are vulnerable as we cannot easily replace ruined materialwith new.
