Can you ensure that your smoke detector will sense fire and sound the alarm in the middle of the night?In 80 percent of the cases where emergency pulls out, smoke detectors are missing where the fire occurred. In the year of 2009, 118 people in Sweden died in fires ? most of them would have survived if there had been a functioning smoke detector.Earlier development of smoke detectors has mainly been focusing on components that sense smoke and alert in case of fire. But in most cases the problem has not been whether the smoke detector was working or not as fully assembled, but rather that it was missing.

During the latter half of the 18th century, when concrete started seeing general use in modern cities, the use of different methods to give the concrete a finished surface texture saw use. One of these was using different methods of mechanically altering the surface using a slew of cutting and crushing techniques with mallet and chisel. This was done in order to hide the often dull and gray look of concrete, and allude to other more expensive and luxurious stones. The work would possibly have been done by experienced stonemasons, using much of the same techniques and tools they would have used while working natural stones. Or did they? This essay explores, through the use of traditional handcrafts and tools, the claim that the working of concrete surfaces can be done with the same tools and skillset as the working of natural stone.

This essay includes the planning and designing of a house as well as writing a rapport about howto increase fire safety in small buildings.More than 6000 homes burn in Sweden every year (Brandskyddsföreningen, 2012c). Thedevastation and the costs are usually very high. This report examines possible measures to reduceboth personal injuries and economic losses resulting from house fires in small buildings.Swedishbuilding regulationsplay a major role when it comes to constructional fire safety. However therequirements inSwedish building regulations are very low for small buildings and this is anargument for raising the requirements.The report shows and describes possible methods to build safer with regards to fire in terms ofmaterials and different building structures. Major focus has been on fire cells but other solutionsare also examined and described.

To work in an unpredictable work environment requires communication that functions well. In every organization it?s important that employees receive information that is relevant yet not confusing. Due to that, our ambition with this study is to understand how rescue effort organizations communicate in meetings; and whether their communication is clear or not. Our subject for this case study is the Emergency Services in the region of Karlstad.

AbstractThis is a study of present day dogs with the purpose to establish a method to investigate archaeological dogs and determine their use in the past. The study has focused on measurements of five bone elements, scapula, humerus, radius, ulna and femur. A principal component analysis has been applied in order to decide which measurements to be further used in the analysis. Different proportions have been calculated on these measurements.A test to try the method has also been done on bones of a wolf and a dog without known background. The results from the different elements are positive, and they narrow the field down to two dog types of which one is more likely to be true than the other.The final results show that, although over lapses between the four different dog groups; hunting dogs, guard/work dogs, sled dogs and shepherd's dogs exists, it is possible to distinguish different dog usage from the proportions of the bones..

This is a final year project considering constructional techniques for joining cavity walls. The project is related to an ongoing scientific programme about the restoration of The City wall of Visby located on Gotland. The programme was set by Riksantikvarieämbetet as a reaction to a collapse of the outer masonry wall shell which took place in February 2012.The City wall of Visby is a medieval fortification built out of limestone during the 13th century. The wall is constructed as a cavity wall with two separate masonry shells connected to each other through an intermediate core. During the 14th century the wall was heightened which lead to a higher stress, especially in the outer wall face.

The thesis aims to examine how companies optimize the human capital from a value creation perspective. The value creation will be related to transfer of knowledge, recruitment, staff turnover and development. The thesis has a deductive approach and six qualitative interviews have been conducted. The results from the interviews will be strengthened with a quantitative data analysis of two measurements; value added per employee and human capital efficiency. The theoretical framework includes definitions of human capital.

This report contains a programming improvement work in a LabVIEW? fire testing furnace control system for SP Fire Technology in Borås. Here materials and products behaviour are tested and evaluated, being exposed to fire. For this task, UGNET is being used for control and surveillance of the testing furnace system. System hardware has been updated gradually through the years, while the software has been neglected.

The manor Fållnäs gård is situated at the northern end of the bay Fållnäsviken, c. 12 km north-west of Nynäshamn, Sweden. A 300 cm long sediment core collected in the bay has been analyzed regarding pollen stratigraphy. AMS 14C dating of terrestrial macrofossils indicates that the sequence covers the last c. 5400 years.The aim has been to study vegetational changes, especially human impact, in the surroundings of Fållnäs gård.

At the beginning of 2011, Sweden started using the European rules for structural design, the Eurocodes, instead of the previous national rules. In both the previous rules and the Eurocodes, it is possible to dimension concrete columns using tabled values. However, the required cross section measurements have increased considerably. Moreover, it is possible to dimension concrete columns using calculations, however, this is unusual.The development of a fire in a fire cell can be divided into the growth stage, the fully developed fire and the cooling phase. The duration of each phase, as well as the temperature, is dependent on a number of factors, e.g.

During the late 1800s fire suppression became increasingly effective in northern Sweden which led to decreased areas of fire-disturbed woodland and successive changes in the structure of forests. In the long run this can pose a serious threat to fire-dependent and fire-favored species. Today some fire-prone forest reserves are burned as a nature conservation act. Often partial cuttings are made before burning, with somewhat different motives. The purpose of the study in LÃ¥ngsidberget nature reserve was to give a general picture of forest history and its affect on today?s forest condition, and to show how partial cuttings affect burning conditions and results. LÃ¥ngsidberget is located close to areas that were colonized during the Middle Ages.

This study investigates a method for identifying human capital and its effect on company valuation. We devise a measure for the efficiency of human capital based on the personnel cost. We include all companies listed in the financial and industry sector on Nasdaq OMX Stockholm in an attempt to examine human capital and its effect on firm valuation. Our results indicate that a higher efficiency of human capital has a positive effect on return on assets. However, we find that our measure can be interpreted in two ways; either as a firm?s level of human capital efficiency or its dependency on human capital, to achieve its net sales and revenue.

This essay is about the burial rites in the passage graves of Falbygden, Västergötland. My questions were: Can the burial ritual be understood by comparing the material culture inside and outside the tombs? What kind of grave offerings did the dead have? Most peculiar are all these beads of amber, what kind of meaning did they have? Was the position of the body a part of the ritual? The time period is the middle Neolithic.I selected four passage graves to investigate: Hjälmars rör (Falköping 3), Rössberga (Valtorp 2), Näs sn 7:2 Kvättak 5:1 and Frälsegården (Gökhem 94).My conclusion was that there are differences between the material culture inside and outside the tombs. Outside the ritual includes fire, inside the material culture are not burned. The material culture outside is more dominant than the finds inside, although the beads of amber are only represented inside and dominates the findings inside.
