Brand i förorten : En studie av etiken i journalistiken
A great fire seized a suburb in a small town in Sweden in the autumn of 2011. Parts of a shopping mall were burnt to the ground by youngsters. Due to the suburb's earlier problems, the event was a tough ethical dilemma for the town's journalists.The purpose of this thesis was to study and examine the local newspapers ethical treatment of this event. How do they motivate their decisions on what to publish and what not to publish? How do the articles treat ethical dilemmas? What do the journalists think about ethical journalism?This study is based on a survey of the articles published about the fire in the two local newspapers seven days after the fire.
Eld som naturvårdare : Kärlväxtflora och vegetationsutveckling efter naturvårdsbränning i två småländska naturreservat
This study has taken place in two nature reserves in the municipality of Uppvidinge in the Kronoberg region in southern Sweden. These have been chosen by the County Administrative Board to be part of a bigger landscape of fire affected nature, and prescribed fire has been implemented in these. The areas are called Ösjöbol and Berga fly and have been burned 2012 and 2013 respectively. Non-burned areas have been inventoried as well. Vascular plants and mineral soil have been inventoried with the Hult-Sernander-Du Rietz scale of five levels. Issues emanate from the County Administrative Board?s goals for prescribed fire: how sticks and herbs were affected, how much soil was uncovered, how the structure and fire favoured species were affected, and how deciduous trees and spruces (Picea abies) were affected. The study shows that the soil increased, as well as the fire favoured species.
Katastrofers implikationer för samhällsarbetet : ? En fallstudie om hur det brottsförebyggande ungdomsarbetet påverkats av branden i Berga
This is a case study about the effects that disasters have on social work. The case in question is the fire in Berga village, Kalmar, which took place the 12: th of October 2011. The aim of this study is to describe the ways in which Kalmar worked crime preventive towards young people before the fire and after. The study also aims to specify if, and how the disaster affected the crime preventive work with young people. In this study we define the fire like a disaster and disaster has the ability to create changes in policy.
Brand i Fulufjällets nationalpark : en brandhistorisk analys med förslag för framtida skötsel
Fire has historically been of great ecological importance in the boreal forests of Sweden. The forest fire regime has, however, varied between different parts of the country. The objective of this thesis is therefore to investigate the fire history in Fulufjället National Park and, on this basis, give suggestions for future fire management.
The reconstruction of fire history was done by cross-dating fire scars in samples taken from living and dead Scots pine (Pinus sylvestris). Local fire chronologies were established at 17 points in the forests in and around Fulufjället National Park by cross-dating fire scars on 54 samples. The oldest year-ring dated from year 968.
Vegetationsutveckling och brandhistorik i Tyresta under 9000 år : en pollenanalytisk studie av en skvattramtallmyr i Tyresta nationalpark, Södermanland
Analyses of pollen and charcoal in peat cores, together with age-structure data of Pinus sylvestris from a Ledum-Pinus-mire in the Tyresta National Park (south-east Sweden) show the regional vegetation succession and fire history over the last 9000 years. Five major stages of mire development are identified: 1. Lake (c 7000-6400 cal BC); 2. Wet fen (c 6400-6000 cal BC); 3. Deciduous fen (c 6000 cal BC to c cal AD 700); 4.
Flygbildsanalys av trädskiktets status efter brand : en metodstudie
During the past years fire has been identified as an important factor for nature conservation in the forest landscape. To accurately quantify the size of a burnt area is obviously important, but also to quantify the degree of fire damage to the tree canopy. Such data are important for assessing the conservation value, and to support planning and management of the burned area in the future.
I have examined how to estimate the status of tree crowns after fire from interpretation of aerial photographs. This is possible because fire changes the structure of tree crowns and this influences the colours in aerial photographs by spectral reflection.
Included in the study are four areas, three of which burned in 2005 and one in 2006.
Analytisk dimensionering av räddningstjänsten i Skåne Nordväst
This report is a part of the process of enhanced cooperation between fire rescue services in the region of North West Scania. The aim of the report is to study and analyze how the fire rescue service should be structured, in terms of rescue units and personnel, if no account is to be taking to the current organization. Two types of accident are considered in the report, traffic accidents and building fires. These are more affected by decreased response time than other accidents. Several suggested organizations are presented and they are evaluated with the computer program REP.
Effekt av brand och bete p? uppkomst av ?rtartade v?xter i restaurerade betesmarker. En j?mf?rande studie
Open ecosystems, such as grasslands and pastures, have naturally been shaped by disturbances like fire and grazing. These processes play a crucial role in creating habitats with high biological diversity, particularly favourable for a wide range of herbaceous plant species. In recent years, many of these disturbances have ceased, leading to encroachment, fragmentation and habitat loss. The aim of this study was to examine and compare the effects of fire, herbivory and a combination of fire and herbivory on the emergence of herbaceous plants. The study was conducted at the Ecopark at Nordens Ark.
Analytisk dimensionering av räddningstjänst : fördjupad analys av insatsförmåga och täckningsgrad inom Räddningstjänsten Syd
In order to reduce the number of casualties and injured from accidents the rescue service must become more efficient and flexible. It is noted that far more people is injured and killed in traffic accidents than from fires. During the daytime the number of accidents in about three times higher than during the night, even so today the number of fire fighters on duty is the same day and night.Two computer models for simulation of different locations of the rescue services are used to determine the best options for placement of the rescue services. A cost-benefit analysis is also used to determine if today's fire stations are efficient for the society from an economical point of view.The results of the different models are that the fire station in Lund is misplaced. The number of ladders in Malmö can be reduced.
Diskussion om röjningsrösen : med teorier om gravrösen i fossil åkermark och skärvstenshögar
This paper aims to investigate the connection between clearance cairns and burial cairns. From this point of view I try to answer the questions why they are built in the same area and why these two different types of cairns are so similary constructed. Further I consider different theories about mounds of fire-cracked stones..
Tillämpning av nya beräkningsmetoder för branddimensionering av träkonstruktioner - analyser och jämförelser
To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.
Experimentell utvärdering av väggreppsmätaren RT3 Curve
I detta examensarbete utvärderas väggreppsmätaren RT3 Curve som tillverkas av Halliday Technologies Inc. RT3 Curve kan liknas vid en liten släpvagn som kopplas bakom en bil. Den mäter friktionen mellan två ytor genom två mätdäck som är monterade med fasta slipvinklar. Den fordonsdynamiska termen slipvinkel är vinkeln mellan ett rullande hjuls färdriktning och den riktning som hjulet pekar i. Detta gör att sidkrafter uppstår när släpvagnen dras bakom bilen.
Jämförelse av stenull- och polyuretanisolering : Brand- och fuktegenskaper i passivhuskonstruktion
This report compares two different types of insulation with regards to fire and moisture. The materials were tested for the company Fiskarhedenvillan AB, for a wall and a roof construction that the company currently uses in the establishment of Sweden's first certified passive house for international standards.Their current material, Rockwool, is compared to a relatively new material on the Swedish market called SEALECTION Agribalance sold by the company ISO Green AB. The material is a type of polyurethane insulation. This insulation material would result in a more efficient execution of the construction as it provides waterproofing and is applied more easily than Rockwool. From a fire standpoint, literature studies and discussions with fire experts led to results.
