The Camassa-Holm (CH) and Hunter-Saxton (HS) equations have an interpretation as geodesic flow equations on the group of diffeomorphisms, preserving the H-1 and. H-1 right-invariant metrics correspondingly. There is an analogy to the Euler equations in hydrodynamics, which describe geodesic flow for a right-invariant metric on the infinite-dimensional group of diffeomorphisms preserving the volume
Traditionally, interdisciplinarity has been taken to require conceptual or theoretical integration. However, in the emerging field of sustainability science this kind of integration is often lacking. Indeed sometimes it is regarded as an obstacle to interdisciplinarity. Drawing on examples from sustainability science, we show that problem-feeding, i.e. the transfer of problems, is a common and fru
For centuries, people have appreciated the taste of wild mushrooms which can be found in nature throughout the European continent and the Fennoscandian peninsula. This is especially so for those of the order of Cantharellales, where you find the Golden Chanterelle among others. Today the commercial aspect of mushroom harvesting has resulted in regulations and guidelines set out by the Nordic Counc
We investigate the strength of the Ultrafilter Lemma in comparison to the Axiom of Choice. In particular, we prove that a number of classical mathematical theorems are equivalent to the Ultrafilter Lemma over $\sf ZF$, and we study a few results which are typically only obtained in $\sf ZFC$ (as opposed to $\sf ZF$) but which can also be proven from the conjunction of $\sf ZF$ with the Ultrafilter
This text discusses the impact of economic liberalization in India in 1991. The aim of this study is to investigate how the 1991 reforms, which increased foreign investments and entrepreneurship, contributed to economic growth. The paper provides a detailed background of the socialist Indian scenario prior to 1991 and highlights the changes that occurred with the liberalization policies and their
In our research paper, we shed light on the various impacts of acculturation and changes in religious consumption in the lives of muslims, who have migrated from the east and are experiencing life in the west. We took into consideration the holy month Ramadan as a religious reference to our study where we examine muslims religious performance during this time. As Ramadan is considered the most spi
Purpose: The thesis aims to address the different roles incumbent firms can take in the emerging plant-based ecosystem and to contribute with new understandings related to these ecosystems. Theoretical framework: The theoretical foundation for the thesis is rooted in theories on systems thinking, ecosystems and with a discussion around the roles that are inherent in ecosystems. This is accompanie
The dynamics of credit spreads are an essential factor to consider for a broad spectrum of stakeholders foremost when valuing corporate bonds and similar instruments. Through a cointegration approach, this paper first examines the relationship between credit spreads of US corporate bonds and US treasury yields using daily data on yield indices of five different credit ratings and three different m
Enhancing the physicochemical and sensory properties of flavoured vodkas using hydrocolloids is of significant interest to the beverage industry. Hydrocolloids like xanthan gum and carboxymethyl cellulose (CMC) can influence texture and stability, yet their specific impacts in alcoholic systems are underexplored. This study aims to evaluate the effect of hydrocolloids on the viscosity, turbidity,
Title: The (Mis)alignment between Offline and Online Brand Image: A Qualitative Study based on Customers’ Brand Associations of the Swedish Beauty Retailer Kicks. Purpose: The purpose is to explore the alignment or misalignment of a beauty retailer’s offline and online brand image based on customers’ brand associations. Theory: To explore a beauty retailer’s offline and online brand image, Kelle
The relationship between Knowledge Management (KM) and Business Intelligence (BI) is di-vided into two steps. First, differences and similarities between the concepts, and second, what interaction the concepts have within organisations. Eight qualitative interviews with ex-perts in the field of BI have been done. The most significant difference is in the knowledge sources, where KM handle explicit
Due to an increasing ease of access to social media outlets, more tourists than ever are able to share their comments, images and videos of travel experiences. As such this user generated content is said to have more of an impact than professionally produced content on the decisions of prospective travellers. On this basis the major objective of this study is to identify the overall perspectives h
International Humanitarian Law has at its core distinctions and classifications: The sphere between jus in bello and jus ad bellum. Between Civilian and Combatant. Between proportional and indiscriminate attack. Between acceptable and prohibited targets. However the two most central distinctions in International Humanitarian Law are the distinction between War and Peacetime and between Internati
To understand the evolution of our galaxy, the chemical abundance patterns and trends within the stars of the different regions are explored. The process of synthesizing these elements reveals key details about the way the stars and, therefore, the galaxy formed. This project focused on the element potassium, K, and specifically its absorption line 7699 Å. The local thermodynamic equilibrium (LTE)
Abstract The care for the environment in investment situations is rising among different groups of investors, due to social and psychological factors. Existing studies on nonpecuniary preferences for the environment are focused on measuring the proportion of individuals with green agendas, whereas we focus on measuring also magnitudes, i.e. how much future wealth are people actually prepared to gi
The Bogoliubov transformation is the starting point for the Hartree-Fock-Bogoliubov method and thus for many theoretical approaches that describe heavy nuclei. This transformation is based on two matrices, denoted by U and V, which are called Bogoliubov amplitudes. In this paper the properties of these matrices are investigated. Bogoliubov amplitudes are generated using BCS wavefunctions. The Bloc
