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
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
Considering climate change, the continuous degradation of the environment, and the uneven distribution of resources, this research project aims to shed light on the social vulnerability of people experiencing extreme weather events and possible connections to social phenomena. Specifically, this project focuses on how vulnerability to extreme weather events affects vulnerability to human trafficki
Purpose: The purpose of this study is to examine the relationship between post merger financial performance and customer reactions on M&As, as well as how the issues of strategic relationships, integration, marketing, and human resources influence these customer reactions. Method: One of the main reasons why M&A research lacks so much of customer reactions is that the methodological main
Free movement of labour and open borders are one of the main principles of the European Union. Workers can relatively easy relocate in the search for new job opportunities and firms compete internationally for productive labour. Corporate taxes affect firms’ profits, and also their investment decisions. The costs associated with employment on the other hand have not been studied to the same extent
The purpose of this study was to examine how women in a social science faculty at a university in Sweden perceive their career possibilities. Given that the Faculty of Social Sciences is one of those predicted to be the first to come under the so-called equality interval, the opportunity structure for women's career development is interpreted as good. In the study, seven semi-structured interv
The thesis main objective is to establish the determinants for granting executive stock options and to examine their impact on performance for firms listed on OMXS30. The analysis is based on accounting data gathered from annual reports and Thomson Datastream. The empirical results display that firms grant stock options to mitigate the principal-agent problem. Furthermore, risk proves to be positi
The crude assumption on log normal stock returns and constant volatility in the Black-Scholes model is a big constraint which constructs smile and skew inconsistent prices. The Heston model and its suggested approximation built on stochastic volatility are introduced and faced against the Black-Scholes model in hope of producing option prices where the smile and skew are taken into account.. As on
This research aims to explore how identity is shaped through the consumption of film cameras. Identity can be formed in numerous ways, through norms and values, social relationships, and much more. In the digital era, there is a lot of pressure on creating and maintaining identity quickly, as social media speeds up identity building practices. To explore how identity can be shaped through physical
The success of a company increasingly depends on the efficiency and effectiveness on its activities along the product life cycle. In the effort of optimizing its activities, companies must integrate themselves. Due to the significance packaging has within many of these activities, it is of utmost importance to integrate product and packaging development activities in order to optimize processes.
This thesis examines whether implied volatility derived from Swedish equity options provides superior predictive information relative to historical volatility for future realized volatility and stock returns, and whether this information improves portfolio risk outcomes. Using monthly option and stock data for OMXS30 firms, the study applies predictive regressions and constructs minimum variance p
This master thesis aims to improve the physical design of smart ear tags for animals. The focus was to minimize the risk of tags falling off or causing harm, while considering environmental and animal welfare aspects. The project followed the methodology of Ulrich & Eppinger’s product development process, which included stages such as planning, concept development, and testing. Data collectio
In recent times, the applications and interest in the flexoelectric properties of nanoscale materials have become increasingly prominent. Here, we investigate the interplay between flexoelectricity and electronic correlations at various degrees of bending using the Hubbard model with the Hartree-Fock approximation. The study focuses primarily on hollow periodic cylindrical lattices of various size
Tuberculosis (TB) affects millions of people annually and remains one of the leading causes of infectious diseases-related deaths in the world. Current anti-TB treatment consists of a prolonged regimen of multiple antibiotics, which effectively eliminates the bacteria when it is not antibiotic resistant. However, large proportions of the TB-treated individuals experience persistent pulmonary dysfu
Water is essential for life. This is particularly true for terrestrial insects, whose small size and high surface-area-to-volume ratios render them especially susceptible to dehydration. To overcome this challenge, insects have evolved sophisticated physiological mechanisms and behavioral strategies to maintain internal ion and water balance despite fluctuating environmental conditions. This chapt
In 1880 Serhiy A. Podolynsky (1850–1891) described the human economy as a metabolic flow of energy and was later praised for it by ecologist Vladimir Vernadsky, whereas his work encountered strong criticism by Friedrich Engels. However, the notes taken by Karl Marx were rather neutral in tone. In this article, we use primary sources in Ukrainian and Russian, including Vernadsky’s diaries and corre
