Utredning av lokal brand i hyllställningar: En studie av ICA Maxi, Storheden, Luleå
Vid dimensionering av lokal brand enligt bilaga C, i EN 1991-1-2, så erfordras en värmeutveckling som beräknas i bilaga E. Boverket hänvisar dock i Europeisk konstruktionsstandard, EKS, 9 att bilaga E inte får användas utan rekommenderar i stället att Boverkets allmänna råd om brandbelastning, BBRBE, bör användas. En problematik vid användandet av BBRBE, är att den inte innehåller några beräkningsmetoder för värmeutvecklingen. Det åvilar därför projektören att vid varje enskilt fall vid analytisk dimensionering använda sig av relevanta beräkningsmetoder för att beräkna effektutvecklingen vid lokal brand.Syftet med det här examensarbetet är därför att utreda och jämföra beräkningsmetoder i Eurokod för lokal brand i hyllställningar i livsmedelsbutiker med simuleringar i FDS, Fire Dynamics Simulator, för att komma fram till slutmålet som är att fastställa en metod för att ta fram brandeffektkurvor och temperatur-profiler vid dimensionering av lokal brand. En metod som baseras på ekvationer från bilaga C och bilaga E i EN 1991-1-2.

Fri rörlighet av varor : Art 34 FEUF och åtgärder med motsvarande verkan - "från Dassonville till Trailers målet"
The characteristics of free movement is the elimination of obstacles to trade between Member States and thus by such, create free movement within the entire union. Therefore art 34 in the Treaty of Lisabon (FEUF) states that all quantative restrictions on imports and measures of equivalent effect are prohibited. The legal approach to measures having equivalent effect is still unclear and the purpose of this paper is therefore to propose a solution to that particular problem. What can be said when it comes to this rule is that the EU-Court has gone from applying a discrimination test to a market access doctrine.According to the Court´s case law, measures having equivalent effects to quantative restrictions are ?All trading rules enacted by Member States which are capable of hindering, directly or indirectly, actually or potentially, intra-community trade?. The question of how to apply the test when it comes to a potential hinder to intra-community trade is still unclear.
Vogler och pergolesis stabat mater: En väg till historiskt informerad uppförandepraxis
The author is active as a musician in the field of historically informed performance practice (HIP) which emanated from the 20th century early music movement. Studying of historical sources has a central role, but the problem of how interpretation and selection of source material is affected by art and music ideals of our time, is commonly acknowledged. Georg Joseph Vogler shows in a series of articles in "Betrachtungen der Mannheimer Tonschule" (1778-1781) how Stabat Mater by Pergolesi could, and in his opininon, should be improved. The purpose of this thesis is to investigate how this source can be used from the standpoint of a performing musician: How can I use Vogler?s methods in my playing?The introduction problematizes Vogler?s action in relation to his time, and to ours.
Alla vill beta men ingen vill bränna : skogshistoria inom Särna-Idre besparingsskog i nordvästra Dalarna
In this work I have tried to reconstruct the forest history within Särna-Idre forest common in northern Dalarna from the 19th century until present time.
The Särna-Idre region has been an extensively used landscape for a long time. Pollen which indicates grazing has been found in samples orginating from the 10th century. Early travellers from the 18th and 19th centuries seem to have been passing trough a "used" landscape. Burned forests on naked ground are described as common. Also large areas are mentioned as undisturbed with lots of large trees, snags and dead wood.
Vindskador vid stickväg i 1:a och 2:a gallring i Boxholm, Östergötland : i stormen Pers fotspår
Wind damages next to strip roads in 1st and 2nd thinning in Boxholm, Östergötland
Anneli Fransson, SLU, inst f sydsvensk skogsvetenskap, Examensarbete no 108
Wind damage is something we are all familiar with since the storms Gudrun (2005) and Per (2007). Research about strip roads and wind damage is very limited. It is commonly known that the trees next to the strip roads more often fall whit heavy winds, and the purpose of this thesis was to verify this statement. Data was collected from first- and second thinnings at Boxholms Skogar AB, Östergötland. In first thinnings data was collected from both spruce and pine stands and second thinnings only data from spruce stands was collected.
Miljöhänsyn vid offentlig upphandling :
One of the biggest challenges in the human history is to prevent environmental pollution. Everybody has an indirect or direct influence on the environment through his or her consumption. The stakeholders are not just interested in price and quality, they are also interested in the circumstances of production and how this affects the environment. By taking environmental concern in public procurement it is possible to speed up the environmental adjustment of services and products. Environmental awareness has become more and more self evident in the environmental work.
Parkplan för Kungälv med förutsättningar för sociala värden :
To work with environments outdoors for people, animals and plants is the main topic for the landscapearchitect.
On several occasions the work is about public places that is to be in relation with other parts of the town. It is about the activities and the life that take place.
The physical environment and the interpretation of it gives possibilities or obstructions
for people who moves around or spend time in it.Since public places, parks and places for movement are used in daily life they strongly effect the people who use the places. The concequences of this effect can be positive or negative experiences.A positive example is a passage over a brook on the way to school while a negative one is to be afraid while passing a tunnel when it is dark outside. Other examples of concequences are stress effect from traffic noice or calming environments with twitter of birds.
The physical environment is also a part of the total interpretation of a town.
Ekosystemtjänster : En studie av kunskapsläge, hinder och strategier inom kommunal förvaltning
?Ecosystem services are the ecosystems direct and indirect contributions of ecosystems to human well-being.? In order to reach the generation target and the environmental objectives it is important to increase the awareness of biodiversity and ecosystem services and it?s importance to human welfare and simultaneously highlighting the value of ecosystem services. The value of ecosystem services should be integrated into economic standpoints, political considerations and other decisions in the society. In today?s society there is a problem concerning that the value of ecosystem services are not considered in economic terms, which can result in solutions that are unfavorable for our welfare (Ministry of Environment, 2012).
Brand i kabelkulvert: En analys av dimensionerande bränder i en kabelkulvert
Vid Akzo Nobel Sundsvall finns en kabelkulvert där en mängd kablar leds. Det sker ingen tillsyn av kulverten och någon konsekvensanalys av brand finns ej. Elektricitet matas genom kulverten till bland annat AGA-gas. Gjorda genomföringar ifrån kulverten till andra utrymmen finns ej dokumenterad och risken för spridning av brand och brandgaser till andra utrymmen finns. Syftet med rapporten är att göra en konsekvensanalys av en brand i kulverten samt utföra beräkningar på olika brandscenarion i kulverten.
"Anders Andersson hade eld i sin tjärdal" : en analys av Jonas Åströms dagböcker 1868-1891
"Anders Andersson had a fire in his tar-kiln ". Analysis of Jonas Åström 's peasant-diary 1868-1891
Peasant diaries are notes written by farmers, crofters and other people connected with small-scale agriculture. The notes give unique information about diverse aspects of rural life, for example, personal relationships and work, travel and regularity of church attendance. One such diary was written by Jonas Åström who lived in the county of Västerbotten, Sweden. The main aim of this study is to describe the work done by farmers in the 19th century, focusing on their use of forest resources, as recorded in his diary.

GMO Food Products - The issue of marketing and selling them in Europe.
Title: GMO Food ProductsThe issue of marketing and selling them in Europe - A Business and Legal Perspective.Author: Shane KingSupervisors: Anneli Carlsson and Ewa RabinowiczProblemThe European Unions regulations in regard to GMO?s and the approval process for both release into the environment, and onto the market, has been under fire by the USA along with Canada and Argentina. The WTO has ruled on this issue in favour of USA et al.The problem that was identified was in regard to consumer opinion in the EU. How could the EU meet its numerous international trade obligations while at the same time meetingthe needs of the citizens of the Union? Added to that was the issue of whether or not the?EU? perspective was indeed an EU perspective or rather the perspective of a fewMember States.
Förändrad markanvändning vid biodrivmedelsproduktion : en empirisk undersökning av svenskproducerade biodrivmedels påverkan på åkermarkens användning
Increasing the use of biofuels is an important part of achieving the EU?s target of 10 percent
renewable energy in the transport sector. However, the competition between biofuels and food
production is an ongoing concern. Also, several studies have indicated a significantly higher
climate impact than was earlier estimated, due to emissions from land use.
In Sweden, both the use and production of biofuels from crops have increased substantially
during the last decade. The purpose of this project is first to present an overview of the Swedish
land use in all sectors.
Cross-sectional study of bovine anaplamosis in South-western Uganda : the impact of wildlife-livestock interface
The tick-borne disease bovine anaplasmosis is primarily caused by Anaplasma marginale. A variety of wild animals act as reservoirs for A. marginale, but the understanding of their role in the epidemiology of A. marginale is yet poor. This cross-sectional study was conducted to
establish if proximity of wildlife affect the prevalence of bovine anaplasmosis in cattle.
