The removal of snow and ice from aircraft prior to take-off is a major task at all airports located in cold climates. Currently the removal of ice and snow is carried out using large amounts of costly and environmentally harmful glycol that is sprayed onto the outer surface of the aircraft. Tougher environmental regulations and a cost conscious market have created a growing need for alternative me
Access to electricity is important to meet the Millennium Development Goals (MDGs). The centralized model of large thermal power stations and a central grid is a conventional system to supply electricity to consumers. This centralized model has failed to provide electricity and to achieve the rural electrification objective in developing countries. Un-electrified areas of the developing world are
Due to the current return of federal aspirations among European politicians in relation to the current economic crisis and integration dead end, this thesis is interested in examining if the United States of Europe, meaning a federal union of the Member States of the European Union (EU), would be a desired state of integration or if it is still a federalistic utopia. Using the theoretical approach
The purpose of the thesis was to design a new rotor blade for the KTH test turbine according to present design guidelines for gas turbines manufactured at Siemens Industrial Turbomachinery in Finspång. Stage one of a real gas turbine was used as a reference for the aerodynamic design providing a starting point for the project. Using similar gas conditions the new rotor blade was optimized with reg
This thesis studies the long-run performance of IPOs. In addition, it differentiates between family firms and non-family firms. The long-run performance is tested on listings on Nasdaq OMX Stockholm over a period from 1997 to 2011. The sample consists of 100 firms, whereas 39 firms are classified as family firms. To test the long-run IPO performance, buy-and-hold abnormal return over a three year
This study investigates the path to high health spending among local governments in Indonesia under the setting where administrative, fiscal, and political decentralization are already in place. The motivation behind this study is that Indonesia still has low level of health outcomes. Small amount of health spending is one prominent reason for this lack of achievement. However, the effort in impro
Under de senaste åren har stora resurser lagts på forskning kring utvecklingen av biomaterial för ersättning av fossil-baserade material. Förpackningsindustrin i synnerhet är en sektor känd för att generera enorma mängder fast avfall, med produkter som inte sällan har betydligt kortare livslängd än sina materialkomponenter. Polylaktid (PLA) är en mångsidig biopolymer som används kommersiellt föIn recent years, large efforts have been put into the research of biomaterial synthesis for the replacement of fossil-based materials. Particularly in the packaging industry, a sector responsible for generating enormous amount of solid waste in which products have a considerably shorter life span than their material components. Polylactic acid (PLA) is a versatile, commercial biopolymer used fo
The aggregation of proteins into amyloid fibrils via erroneous folding, also known as misfolding, occurs in several diseases. As a consequence, the study of the kinetics and thermodynamics of this process is currently intensely pursued. Here, we study a minimalistic lattice-based model for amyloid formation using Monte Carlo techniques to sample the grand canonical ensemble, where the chemical pot
The relationship between business cycles and mortality has been a highly debated subject in the field of economics. The majority of previous studies, using the unemployment rate as the main proxy for macroeconomic conditions, have found ambiguous effects largely depending on how the effect is estimated. This thesis follows the methodology used by Ruhm (2000), but instead applies aggregate data for
The DARPA Grand Challenge (DGC) 2005 was a competition, in form of a desert race for autonomous ground vehicles, arranged by the U.S. Defense Advanced Research Project Agency (DARPA). The purpose was to encourage research and development of related technology. The objective of the race was to track a distance of 131.6 miles in less than 10 hours without any human interaction. Only public GPS signa
Syftet med vår uppsats var att utreda behovet av multilingvistisk kundservice på den svenska marknaden samt att studera hur företag hanterar kunder med icke-svensk bakgrund. Vårt sekundära syfte vara att undersöka affärsmöjligheter för ett multilingvistiskt call center. Uppsatsens teoretiska ramverk består av kundbaserad teori, där teorier kring Customer Relation Management, kundservice, call cent
This thesis seeks to answer the question of whether obligations to primary pandemic prevention and bio-risk management can be derived from the human right to health. The definition of the right to health in Article 12 of the International Covenant on Economic, Social, and Cultural Rights (ICESCR) was selected, as it is the broadest definition of the right to health in international human rights la
This thesis offers an overview of the relatively new family of Rosenbrock-Krylov numerical methods for ODEs. These methods are a further development of Rosenbrock methods, using a lower-dimension approximation of the Jacobian. The thesis gives the mathematical background to Rosenbrock-Krylov methods by first presenting Runge-Kutta methods and Rosenbrock methods, followed by the concept of Krylov s
There is a growing demand from policy makers for businesses to help close the consumer intention-action gap for sustainable product choice and strengthen the green economy. Moreover, there is increased interest from consumers in brands that are transparent about their environmental impact. This is not least the case for the focus sector of this study, food products, an industry responsible for aro
Background: The case company is a Swedish family-owned business, operating in the agri-food industry. Their philosophy is to develop, produce, and sell frozen products from the vegetable kingdom with a focus to be organic and convenient. The company has realized that the production layout and the material flow cause a lot of waste and have great potential for improvements regarding efficiency in p
This thesis aims to investigate the different mechanisms that Chinese companies in green industries used to acquire technological capabilities and how they changed over time. The thesis also aims to examine how the geographical pattern in outbound Chinese greenfield foreign direct investment has changed over time. By examining the inbound and outbound greenfield foreign direct investment pattern i
Public participation during urban development is key for setting a project up for success and for supporting sustainable growth, but current detailed development plans available in paper-based 2D format are difficult for the public to understand. The literature has shown that the introduction of 3D visualizations can improve citizens’ understanding of a plan proposal; however, moving from static 2
The purpose of this study is to investigate if and to what extent environmental sustainability is a contributing factor in the purchase decision of craft beer among young adults. In addition, the study aims to understand how different purchasing factors are related to each other in the craft beer purchase decision. The purpose is to gain a greater understanding for the industry of small scale prod
Galectins are small, carbohydrate-binding proteins widely distributed among different cells and tissues in the human body. Due to their abundance, these proteins are involved in many processes and diseases. Among the different types of galectins found in the human body, galectin-1 and galectin-3 are the most common, thus the most targeted and studied. Particularly, galectin-3 is the only chimeric
