Vulkanisk aktivitet har sedan längre observerats ha en stor påverkan på klimatet. Svavelaerosoler från utbrott bildar molntäcken som kan sprida sig runt globen och hindrar en del solstrålar från att nå markytan. Till följd av detta sker en temperaturminskning av marknära luft under det område som molnet täcker. Den här kandidatuppsatsen reder ut skillnaden mellan inverkan på klimatet samt atmosfärVolcanic activity has long been observed to have a great impact on climate. Sulfate aerosols from an eruption form aerosol clouds that can spread around the globe and prevent some solar radiation from reaching the surface of the Earth. As a result, there will be a reduction of the surface air temperature below the aerosol cloud. This bachelor thesis discusses the difference between the impact on t

Under en längre tid har svenska kommuner präglats av en målstyrd verksamhetsstyrning där kontroll, mätning och uppföljningar funnits vid varje målsättning. Samtidigt satsar den offentliga sektorn på innovationsarbetet för att kunna utvecklas i takt med omvärlden. Trots detta finns det en problematik med innovationsutvecklingen då den ofta förknippas med andra branscher och tekniska uppfinningar. D

Korslimmat trä, KL-trä, är ett förhållandevis nytt byggnadsmaterial i byggbranschen. Det består av ett udda antal skikt av lameller av konstruktionsvirke, där varje skikt av lameller ligger roterade 90 grader i förhållande till intilliggande skikt. Materialet används både i den bärande stommen och som stomkomplettering i form av exempelvis trappor. Idag finns endast en etablerad tillverkare på dCross-laminated timber, CLT, is a rather new building material. It consists of an odd number of layers consisting of lumber boards stacked together, where each layer is rotated 90 degrees in comparison to the adjacent layers. The material is used both as a load-carrying element as well as a non-load-carrying element, such as stairs. Today there is only one established producer of CLT in Sweden. D

The purpose of our study is to research the sequence of strategy and structure. Due to a theoretical gap between the propositions; strategy follows structure and structure follows strategy, this indicates the need for new research in today’s dynamic environment. According to the chosen dimensions, the sequence initially follows the ideas of the structure follows strategy. However, as the strategy

This study explores how narrative identity construction of young entrepreneurs is influenced through sensemaking processes based on storytelling. In order to do so, this study has been conducted with eleven participants of an entrepreneurial hub. This entrepreneurial hub is actively engaged in training and developing skills of young entrepreneurs. The participants in our study were considered youn

This report provides an analysis and evaluation of the current spatial, environmental and financial resilience of Rågsved Centre in Stockholm. Furthermore, local future risks on resilience are also discussed and the total analysis is synthesised in a new resilient spatial interpretation of the centre. Methods of analysis include a narrative format that comprise of twelve semi-structured interviews

Why some civil wars end for good and others start up again is a complex question that inhibits many factors. This thesis argues, that the cohesiveness of rebel groups is one of the important ones in the post-conflict phase. During civil war the rebel groups can build up their political, military, and societal profile. In the aftermath of a civil war, this profile becomes one of the deciding factor

The global spread of mobile phones provides developing countries with new opportunities to spark economic growth and to improve the quality of life of their people. One specific service that emerged in this context is mobile money. Widely recognized as the most successful example is the service M-PESA in Kenya. In 2013 Kenya introduced a 10% excise fee on all financial transaction fees, including

Thesis purpose: Consumers’ resistance to reform habits and change established behaviours may impede the transition of the fashion industry from a largely linear, to a circular economy.Thus, the purpose of this study is to provide an understanding of how young, female consumers perceive disruptive circular business model innovations in fashion. Based on this, the potential of respective models is e

The idea of Universal Primary Education has always been an essential part of the core concept of development. Whether gained through formal or informal channels has played relatively a little role, as long as the end-result has been an individual, who has obtained the basic level of schooling. The concept of quality education however, has not been the focus of this basic education until only recen

In April of 2019, Japan implemented a new visa system projected to bring in approximately 345,000 semi-skilled foreign workers into the country over several years. As the Japanese society also faces an ageing population and simultaneously a diminishing workforce, it has turned to immigrant workers to fill labor shortages. This influx of foreigners may result in cultural, societal, and economic iss

Fallstudie av en skogsplantskola – rester av DDT i jorden utgör än idag en hög risk för rovfåglar och rovdjur. Trots att användningen av insektsgiftet diklordifenyltrikloretan (DDT) sedan länge varit förbjuden i Sverige finns rester kvar i jorden på platser där det använts. Anledningen till att det finns kvar är att DDT är mycket svårnedbrytbart. Eftersom detta ämne även har förmåga att bioackumuAlthough prohibited since decades, dichlorodiphenyltrichloroethane (DDT) and its metabolites still remain in the soil and pose a threat to ecosystems, where especially birds are susceptible to toxic effects. In this thesis, a model developed in the 1990s was used and updated in order to estimate the risks of DDT to top predators at a forest-plant nursery site. Unusually high concentrations of DDT

Av miljö- och hållbarhetsmässiga skäl finns idag ett ökat intresse att använda trä som byggnadsmaterial. Björk har historiskt sett inte används i lastbärande strukturer på grund av dålig beständighet och låg formstabilitet. Genom den kemiska modifieringsprocessen acetylering, kan båda dessa egenskaperna förbättras. För att kunna använda det modifierade träet i lastbärande strukturer måste man dockModication of wood is carried out to increase the durability and dimensional stability of wood, and one of the modication methods is acetylation. Acetylation of wood means that polymers in the cell wall react with acetic anhydride. Today, acetylated wood is rarely used in load-bearing structures and there are only a few studies on how the fracture characteristics are affected by acetylation. A stu

Problem – Although core values and conflicts have been thoroughly explored in organizational theory, few attempts have been made to explain their combined impact on the entrepreneurial environment. Since investors and entrepreneurs act as the core decision makers within a venture, understanding the impact of their underlying motivations in relation to conflicts can provide valuable insights. Aim –

The Museum in Helsinki explores the architectural challenges in adding properties to a culturally significant site without disturbing it. The framework for this thesis is given by an open architectural competition with the objective to find a suitable extension to the National Museum in Helsinki. How does one design a suitable extension to a culturally significant and fragile site?

After recieving the diplomas from the idea competition win together with two colleagues nothing really happened in the Granite Castle in Itäsatama, Hanko. Some makeshift flea markets and coffee booths were put in the empty shell of the previous granite quarry but in the greater scale it remained a shadow from its former past. Hanko’s unequable tourist season concentrates during peak summer leaving

Building permit automation has become a rising international topic in the past decade due to its convenience and efficiency. Automated compliance checking saves time and resources, which is beneficial for the construction industry. Researchers have already automated parts of the building permit process and the results proved that automated building requirement compliance checking is efficient. Thi

Under de senare åren har debatten om polisens omorganisation väckt många heta diskussioner. Omorganisationens syfte var att skapa tydligare styrning och bättre förutsättningar för högre kvalitet, ökad kostnadseffektivitet, större flexibilitet och förbättrade resultat inom den polisiära verksamheten genom att göra en enhetlig polisorganisation istället för 21 mindre polismyndigheter. Uppsatsens sy
