Introduktion till icke-standard analys - Ett bevis av transferprincipen och en explicit konstruktion av Brownsk rörelse
I denna rapport konstrueras inledningsvis hyperreella tal från reella tal. Vi definierar aritmetik för skuggor av hyperreella tal och presenterar en icke-standard teori för serier och konvergens utifrån denna konstruktion.Förfarandet generaliseras sedan genom att skapa en icke-standard modell till matematisk analys utifrån en mängdteoretisk modell i ZF, som ett led i konstruktionen presenteras teori för filter och ultraprodukter. Vi visar sedan transferprincipen och bygger upp internalitetsbegreppet för att studera relationer mellan standard ochicke-standard modellerna för att kunna härledda standardresultat från icke-standard resultat. Avslutningsvistillämpas teorin för att skapa en explicit icke-standard konstruktion av Brownsk rörelse och vi ger ett bevis föratt denna konstruktion är ekvivalent med standard formuleringen..
Den livgivande elden och det livsviktiga bränslet : Bruket av eld och behovet av bränsle på mesolitiska och tidigneolitiska boplatser i Norrland.
Research on Stone Age hunters and gatherers in Norrland has been lively since the 1960s. Central to this research are questions about the organization of society, sedentariness, continuity and resource management. One central part of life in the taiga is the need for fire and fuel. This aspect has been little discussed in conjunction with the mentioned research questions. My goal is to show that the matter of fire and fuel is an important one that needs to be taken in to consideration when discussing Stone Age Norrland and hunter/gatherers.
Trädföryngring i låga gropar uppkomna vid brand i boreal naturskog :
This study was conducted in the "Kåtaberget" forest reserve in Västerbotten in the summer of 1999. In the summer of 1995, a prescribed burning was performed in the reserve. In some places where coarse dry woody debris (logs and stumps) was present, the fire consumed the wood, as well as parts of the humus layer, creating deep-burned patches. The low intensity ground fire also created dead woody debris by burning off living trees with open fire scars, as well as standing dead trees.
In this study, the post-fire tree seedling establishment was examined, with special attention given to the former presence of woody debris. The study also includes a survey of the areal extent of deep-burned patches, as well as an examination of tree seedling establishment in these patches, compared to other burnt ground.
Folkrätt och kärnvapen : Om tillämpningen av NPT som icke-spridning och nedrustningsavtal
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.
Safire : Unik brandvarnare med smart design för ökad säkerhet
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.
Förebyggande Brandskydd
The number of residential fires has not declined sufficiently since the smoke alarm entranced the Swedish homes, fires lead to devastating consequences in which possessions, homes and worst of all human lives are at stake. Every year, about 80 people get killed and more than 500 get´s injured in residential fires, often due to lack of safety equipment. The number of fires caused by electrical appliances has risen and taken over a period of ten years the fire caused by a forgotten stove has increased by 70 percent. Preventing the risk that a fire would start on the stove would saves money, worry and most importantly, lives..
Brandsäkerhet i ett småhus
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.

Ugnet - Provugnsstyrning med LabVIEW
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.
Påverkas miljökuznetskurvan olika av ekonomisk frihet än av demokrati
According to the theory of environmental Kuznets curve there is a relationship between carbon emissions and GDP. The relationship has an inverted U-shape. Carbon emissions rise initially and then decreases once a certain level of GDP is obtained.This essay interprets earlier studies in the field of environmental economics and uses public choice to seek answer on how the population acts on aggregate level. This essay analyses 115 countries in cross-sectional data. The analysis shows that there is a significant relationship between carbon dioxide emissions and GDP that is increasing at first and then decreases for a certain level of GDP.
Att återställa en naturlig ordning : skogshistoria och restaureringsbränning i Långsidbergets naturreservat
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 Långsidberget 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.
Långsidberget is located close to areas that were colonized during the Middle Ages.
Skogsbrandens påverkan på död ved :
Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris).
Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.
Att jämställdhetsintegrera mans- och kvinnodominerade kommunala förvaltningar : En jämförande studie mellan räddningstjänsten och vård- och omsorgsförvaltningen i Växjö kommun
This thesis aims to describe the differences and similarities between a male dominated sector and a female dominated sector based on gender mainstreaming documentation as well as through interviews with people working within the sectors. The sectors that were chosen in this study were the fire department and the nursing and care administration of Växjö municipality. Both of the administrations? genders mainstreaming documents were subjected to content analysis in order to describe differences and similarities between the administrations. The analysis found that there were differences in approaches between the administrations were the nursing and care administration had aims of achieving a specified amount of men working within the administration, which the fire department didn?t have.
Skärvstenshögar med människoben i norra Mälarområdet
Mounds of fire-cracked stones is a typical Bronze Age monument for the region around lake Mälaren. They are usually, because of their content, interpreted as piles of rubbish. But as they often have kerbs, are situated on cemeteries and sometimes contain human bones, the traditional interpretation is not fully satisfactory.The main focus of this essay is on the mounds of fire-cracked stones which contain human bones in the region north of lake Mälaren. With a detailed study of these, and a comparison with those without human bones, my aim is to get closer to an explanation why the human bones were deposited. The essay consist of a compilation of 98 excavated mounds and a database with various information gathered from excavation reports and archive documents.With different kinds of osteological aspects taken in consideration, the study shows that human bones have been found in about a third of the mounds.
