The red deer is an animal that most of us know and expect when speaking of big animals in the Swedish fauna. But this has not always been the case. The red deer was almost extinct in the beginning of the 20th century, the life force is mostly regained today but there are still hurdles in the way. The increase in population of the red deer mean an economic conflict with land owners because of its
This study explores the roles of genetic variation and phenotypic plasticity for explaining patterns of local wing colour variation in the common blue butterfly, Polyommatus icarus. Polyommatus icarus is one of the most widespread species of butterflies in Europe. Across its range, the female varies a lot in its dorsal colour, from all brown to almost totally blue. It has been suggested that, in S
The focal quest of this research is to find whether the repression of trade unions is the proximate cause of inability to improve conditions of work in RMG sector of Bangladesh. This research goes deep with several corresponding quests on inquiring about the international obligation of Bangladesh to protect trade union, the scope of international legal system that offered its advice, trade union’s
Electrification of energy demand is seen as one of the key elements of energy transition toward decarbonisation. E-mobility is one main side of the electrification process, and it is considered as a crucial way to reduce the emissions of the transport sector. A core element for a widespread adoption of electric vehicles (EVs) is the deployment of the charging infrastructure, and installing a micro
Niche theory predicts that cooccurring species must differ in their use of environments in order to coexist, thereby diversity can be maintained in a community. However, ecologically similar species do frequently occur in nature, hence species inhabit similar physical environs and share single underling resources. In coexisting species with a similar niche, ecological drift is thought to eventuall
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
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
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
