Det senaste århundradet har cirka 380 vulkaner varit aktiva. Vid vulkanisk aktivitet förs naturliga ämnen upp från jordens inre. Dessa ämnen kan sedan släppas ut i form av bland annat gaser och askor. De ämnen som frigörs kan ha en skadlig effekt på människors hälsa och orsaka både tillfälliga och kroniska åkommor. Partiklarnas farlighet beror bland annat på sammansättning, storleksfördelning, konThe last century approximately 380 volcanoes have been active. Volcanic activity brings up natural ele-ments from deep within the Earth. These elements can then be released into the atmosphere in the form of gases and ash, etc. The released elements may be harmful to humans and cause both temporary and chronic diseases. How hazardous the particles in the emissions are depends, among other things,

Kandidatarbetets syfte har varit att ta fram ett hjälpmedel för studenter på sedimentologikursen vid Geologiska institutionen på Lunds universitet. Hjälpmedlet är tänkt att kunna användas utan lärares hjälp då ett ökat studentantal och försämrad ekonomi på institutionen begränsar lärarnas möjlighet att kunna ge alla studenter den hjälp de behöver för att nå kursmålen. Enkätundersökningar och kursvThe purpose of this Bachelor thesis has been to create an aid for the students at the Department of Geology at Lund’s University. The resource is supposed to be usable without assistance from a teacher. This since the number of students has increased markedly over the last few years while the economic means of the department have decreased. This has reduced the teachers abilities to give all the s

Sverige är ett land med många deponier som har skiftande föroreningsnivåer. Deponin i Getabjär har tidigare klassats som riskklass 3, måttlig risk. Mycket till stor del eftersom den damm som samlar upp dess lakvatten ansetts tät och säker. På senare år har dock lakvattendammens täthet ifrågasatts vilket har lett till denna miljögeologiska undersökning. Området framför lakvattendammen och omgivningSweden is a country with many landfills with varying levels of pollution. The landfill in Getabjär has previously been classified as class 3, moderate risk. Mostly because of the pond that collects the leachate has been expected to be secure. Although, in recent years the security of the leachate pond has been questioned which has led to this geological survey. The area in front of the leachate po

The formation of smooth quasi-periodic patterns in static discrete reaction-diffusion systems of various kinds is here studied from a mathematical point of view. The regularity of the patterns can be attributed to the integrability of the system, so that, when searching for such patterns in a system, it is important to investigate whether or not there exist any conserved quantities. The work prese

Bakgrund: Diatermi är ett elektriskt medicintekniskt instrument som leder högfrekvent ström. Med diatermi är det möjligt att blodstilla genom koagulering och att skära i vävnaden. Vid diatermianvändning utvecklas rök på grund av de höga temperaturerna, det är en känd faktor att denna rök innehåller hälsoskadliga partiklar Syfte: Syftet var att observera hur ofta och hur lång tid operationssjuksköt

This essay describes different solutions for how to better regulate the market short- and long term, more cost efficiently and environmentally sustainable for emissions trading in the European Union´s trading system EU ETS. We analyse six different approaches to intervene the market. These six are; cancellation of allowances, revision of the reduction rate, backloading, extending demand, price flo

Tre av WSP Sverige AB genomförda geotekniska undersökningar har studerats. Samtliga är lokaliserade i Skåne. Projekten har valts i syfte att skapa en övergripande förståelse för hur geologin i Skåne påver-kar geoteknikers metodval och arbetssätt i förhållande till aktuell konstruktion. Geologin i Skåne skiljer sig från övriga Sveriges. Bergrunden är i nordvästra Skåne kristallin och i sydvästra SkThree geotechnical investigations made by WSP Sverige AB have been studied. All are located in Scania, Sweden. The projects have been studied in order to create an overall understanding of how the geology of Scania affects the geotechnical engineer choice of methods and approach in relation to the current construction. The geology of Scania is distinct from the rest of Sweden. The bedrock in the n

The Dannemora mine is located in Östhammars municipality in northeastern Bergslagen. The mine has a history that stretches back to the late 1400s and was in operation until 1992. Dannemora Mineral resumed operations at the mine in 2012. The mineral magnetite is mined for iron production through a modified sublevel caving. The ore is bound in different types of carbonate bedrock with a complex form

Rejmyre i Östergötlands län är ett litet samhälle med cirka 1000 invånare. Enligt uppgifter från befolkningen har det framkommit att glasavfall förekommer spritt i privata och kommunala trädgårdar i samhället. Glasavfallet härrör sannolikt från det centralt belägna glasbruket i samhället. Historiskt har bland annat arsenik, bly och kadmium använts i glastillverkningen, ämnen som idag vanligtvis inRejmyre in Östergötland County is a small village of about 1000 residents. According to existing data, glass waste is scattered in private and communal gardens in the village. Glass waste has been produced since 1810 from the local glass industry. Historically, lead, cadmium, and even arsenic were used in manufacturing glass. However, these substances are no longer used in modern glass production.

Studies about profession have shown that a profession is not homogeneous, but consists of various segments. These segments have some interests and goals in common, but also differ from one another regarding these interests and goals. The differences in interests between the segments can result in a competition about whose interest are more important. Furthermore an important part of the competitio

Abstract During this study we interviewed five young women who have faced growing up in homes with problems such as substance abusing parents, parents with psychological illnesses and violence. The purpose of this paper is to study these five young women’s experiences of participating in a support group for children and teenagers. Due to our purpose we asked ourselves three questions 1. How did th

This thesis aims to explore social work practices in relation to sex work. It addresses the research question of what challenges, trends and implications evolve for professional social work in Germany once effective practices in response to prostitution have been identified. These issues are explored through the method of qualitative interviews. The study uses social stigma theory as a theoretica

The aim of this study is to contribute to the existing literature on co-creation in investigating consumers’ motives for participation on the one hand and possible effects of this participation on brand knowledge on the other. It thus provides a link between co-creation, motivation, and branding literature. A constructionist ontological stance and interpretive epistemology led us to the research p

Denna uppsats har som syfte att utreda innebörden av begreppet ”penninglån” som återfinns i låneförbudsreglerna i 21 kap. aktiebolagslagen (2005:551). Frågan som besvaras är: - Vad innebär begreppet ”penninglån” enligt 21 kap. ABL? Grunddefinitionen av penninglån är en försträckning där transaktionen består av en genusvara, i form av penningar. I lagtexten finns det relativt lite vägledning krinThis paper aims to investigate the meaning of the term "cash loan" found in the loan prohibition rules in 21st chapter of the Swedish Companies Act (2005:551). The question to be answered is: - What does the term "cash loan" in 21st chapter of the Swedish Companies Act mean? The basic definition of cash loan is a loan where the transaction consists in the form of money. The t

This thesis aims to examine if the Swedish Democrats base their criticism against EU on their nationalistic ideas and if these can be pursued in the European Parliament. The theory describes nationalism as an ideology and the European Union as a integration project. By describing these two from different angles a clear opposition can be found. A critical idea analysis is used on the collected data

In this study I present a theoretical model based on Marx´s critique of political economy, specific readings of Marx´s work and the regulation approach. This model will be used to explain long waves and cycles in long term economic growth, creative destruction (i.e the relation between technological leaps and economic crisis) and the ways in which these processes correspond to institutional develo

Arbetet utgör en stor bit av det pussel som bildar våra liv, därför är arbetets mening en central del i våra liv. En människas självidentitet är nära kopplat till hennes yrke eller en speciell titel. Giddens (1999) visar hur vår definition av självidentiteten i det moderna västerländska samhället, går ifrån att vara traditionsbundet till att kravet på livsval blir för stora och till slut omöjliga

This bachelor thesis contains an introduction into supersymmetric quantum mechanics(SUSYQM). SUSYQM provides a different way of solving quantum mechanical problems. The thesis explains the basic concepts of SUSYQM, such as the factorization of a Hamiltonian, the definition of its superpotential and the shape invariant potentials. The SUSYQM framework was applied to some problems such as the infini

Our interest for this subject was awakened by the complexity with teachers having to report their students for being physically or psychically abused or neglected at home. Our aim in this study has been to discover junior school teachers’ idea on the mandatory reporting law between schools and social services in Sweden. Due to this purpose, interviews have been made with six junior school teachers

Sociala medier har kommit att utgöra en stor del av dagens kommunikation. Organisationer använder dessa i sitt kommunikationsarbete utan att besitta större kunskap om hur verktyget ska hanteras för att nå sin fulla potential. Dagens forskning om sociala medier saknar till stor del ett kritiskt förhållningssätt. Det diskuteras inte om organisationer ska använda sociala medier, utan snarare när och Social media forms a major part of today's communication. Organizations choose to adapt this in their work with communication, but lack sufficient understanding of how the tool should be handled in order to reach full potential. Today's research on the social media largely lacks a critical approach. It is not discussed whether organizations should use social media, but rather when and how.
