During the Age of Mass Migration, 30 million Europeans left their home countries and emigrated to the United States. Sweden had one of the highest out-migration rates of the era. Between 1860 to 1920, around 1.3 million people–a quarter of the population–left Sweden to seek opportunity in the United States. This essay delves into one particular aspect of this historic migration episode. I study t
Measuring signals with high frequency common mode components are typically prone to measurement errors due to low common mode rejection at high frequencies. The purpose of this master thesis is to design a measurement probe that presents sufficient common mode rejection to measure current on high voltage motor drives directly at the switching stage, before filtering. Outlined in this work is the
Metod: Denna studie har utgått från en kvalitativ metod. Det har använts två metoder eftersom det bidragit till att studien skapat en mer korrekt bild av området som undersökts. De metoder som använts är kvalitativa intervjuer och iakttagelser. Teorier: Olika teoretiska ansatser har diskuteras i koppling till begreppet förtroende. Teorierna har delats upp i fysiska marknadsföringskanaler och digi
The collaborative economy represents a paradigm shift that could help to address the economic, social and environmental problems of our time. However, its ability to actually deliver that promise is highly disputed. This thesis aims to address the knowledge gap of the types of value that organisations based on collaborative consumption and production actually create, and the strategies that they u
Wine production has been demonstrated to negatively impact on the environment in a number of ways, threatening the well being of ecosystems and a sustainable future of the industry. With a general need for reducing environmental impacts; optimization of water resources has been identified the most critical environmental aspect in relation to wine production. Yet, several studies point towards inef
Today, many cities around the world are looking for means to reduce their consumption-originated emissions and in this way improve their sustainability. Consequently, local governments are becoming increasingly interested in the potential of the ‘sharing economy’ (SE). By enabling the consumption of resources and services through sharing as opposed to purchasing goods for ownership, urban sharing
Public procurement and the purchasing of goods, services and works comprises about 14% of the European gross domestic product (GDP). Procurement initiatives, guidance and tools therefore can have significant influence to leverage demands for more sustainable and circular products and services. This study explores the current circular public procurement (CPP) landscape, looking at barriers and oppo
Bin i södra Indien Vilda bin är mycket viktiga för både vilda blommor och grödor, eftersom de hjälper till att pollinera dem så att de kan bilda frön och sätta frukt. Över hela världen har dock antalet vilda bin minskat vilket kan innebära problem för både ekosystem och jordbruket. En stor orsaken till minskningarna är att jordbrukslandskap har intensifierats, vilket har gjort att landskapet har 1. Wild bees are very important for pollination of both wild flowers and agricultural crops, benefitting seed set and yields. However, declines in bee populations have been observed across the world and it has been proposed that the intensification of agriculture including landscape simplification by loss of natural habitats, is a major reason for these declines. India is undergoing large-scale ag
Seafood can be a potential source of contaminants and when consumed contribute to an increased exposure of these substances. Per- and poly-fluoroalkyl substances (PFASs) are contaminants accumulating in our seafood and are therefore an emerging concern. It has been suggested that cooking seafood can influence the concentration of heavy metals and other organic contaminants, however, few studies ha
The unicellular Gonyostomum semen (class Raphidophyceae) is an invasive microalga which can dominate phytoplankton communities during blooms, with economic and ecological consequences. Its abundance in European freshwaters has been mainly explained by water temperature, colour, and acidity. While low pH and brown colour are common features of lakes containing the species, it has also been found in
7 miljoner människor dör varje år på grund av cigarrettrökning. Idag finns det flera olika produkter på marknaden som kan hjälpa personer att sluta denna dåliga vana. Den första var Nicorette® tuggummin. När McNeil AB producerar Nicorette® tuggummin, följer McNeil de strikta kraven på kvalité som de regulatoriska myndigheterna kräver. Dessa krav tvingar McNeil att slänga tonvis av tuggummin varje McNeil AB produces pharmaceutical chewing gums that contains nicotine. Since this smoking cessation product is a pharmaceutical, the regulatory agencies demand that any gums outside pre-set specifications are discarded. Some batches have more discarded material than others, due to the variability in the manufacturing process. By analysing this variability, the personnel could make choices that low
The aim of this thesis is to investigate if the Lutheran heritage, represented by a comparison between early Lutheran writings and Luther’s source of inspiration Theologia Germanica, can provide a starting point for potentially unifying dialogues within Christian circles. The background of this pursuit of unity is the ecumenical problem of the seemingly opposite views of how faith and deeds relate
Waste management is one of the key environmental issues identified in Sri Lanka. Waste generation is linked with the increase of population and urbanization. Polyethylene and other plastics have become a significant consumable material in lifestyles of the public as well as all types of industries in the country. The plastic consumption is high with the sophistication of living standards of the li
Since the introduction of Edison’s lightbulb over one-hundred years ago, humanity has struggled to keep up with electrification for all. With global attention now aimed at sustainable energy production, the struggle becomes more complex by not only obliging energy access, but access to clean energy. The concept of microgrids has been promising for filling in the demand, but not quickly enough to m
The world's fisheries have been in decline for more than forty years. In Mexico, about 80% of the fishery resources are at maximum capacity levels or overexploited. Given the magnitude of the problem, there is a need for solutions that involve all actors in the fish supply chain. However, solutions and research on how actors in the middle of the supply chain such as restaurants can be integrat
Electronic products consist of substances that can be harmful to human health and the environment if exposed or leaked during the product use and end-of-life phases. Full Material Disclosure (FMD), which usually requires suppliers to disclose on the concentrations or masses of all substances in a product, is one method of increasing supply chain transparency on chemicals in products. This case stu
At the 3 MeV light ion accelerator of the Lund Ion Beam Analysis Facility (LIBAF), a beamline is about to be constructed with the purpose of producing neutrons as a higher yield complement to the current Source-Testing Facility. When operational, the beamline will provide the possibility of tagging both thermal and fast neutrons. These neutrons will be used to test and characterise new available m
Denna magisteruppsats baseras på en översättning av 6000 ord av Donatella Barbieris bok Costume in Performance - Materiality, Culture, and the Body (2017). Uppsatsen består av tre delar. Den första delen är en källtextanalys där textens kontext och viktigaste drag presenteras enligt Hellspong & Ledins (1997) analysmodell. Därefter följer överväganden inför översättningen med en kort diskussion
The paper focuses on three key factors in WTI crude oil futures market: Convenience yield, inventory level and price volatility. The main purpose of the paper is to investigate the relation between those three key factors and analyze how those key factors will affect the market trading behaviors. Market trading behaviors could be measured from various aspects though, our paper will use open intere
Musical meaning is multifaceted: both highly sensory and yet often abstract, able to cross cultural boundaries and yet embedded in specific traditions. For the most part it is not denotational (Monelle, 1991). Nevertheless, in “programmatic music”, musical themes are intended to refer to worldly objects and events on the basis of iconic (and indexical) grounds. Such non-arbitrariness of the sound-
