This study is evaluating two methods in order to calculate predicted no effect concentrations (PNECs) used in environmental risk assessment for three chemicals (α-Amylcinnamaldehyde, 1-tridecanol and paracetamol). The methods used are Species Sensitivity Distributions (SSD) and the guideline from European Chemicals Agency (ECHA): “Guidance on information requirements and chemical safety assessment
Lumazine Synthase forms pentamers, C5 in some organism and icodahedra, Ih in other. The aim of this project is to investigate which evolutionary steps could have led the pentamers to assembly into icosahedral capsids. Therefore prevoius work has been performed to reconstruct ancestral sequences for the pentameric and icosahedral forms of Lumazine Synthase. The icosahedral sequence had been express
The purpose of this study was to investigate three aspects of asexuality. This was achieved through conducting six interviews with self identified asexuals, an observation on a meeting for asexuals, an analysis of what functions the two organisations for asexuals, Nätverket Asexuell and AVEN have, and a content analysis concerning how people talk about a lack of sexual lust on the internet. The co
For various political and economic reasons European sugar farmers and producers have received large subsidies from the EU. The goal of this thesis is to analyze these sugar subsidies and their effect on world market prices and production level in the EU, using statistical data from the mid 1980’s and onward. The analysis encompasses the mechanisms and consequences of EU sugar subsidies with a part
Minority group conflicts and marginalization has been a challenge to the peaceful existence and development of many African countries. This thesis is based on the topic: The Anglophone problem: Political representation and Socio-economic development. Cameroon is the case since its independence in 1960 till date. The Anglophones who form the minority claim they are marginalized by the Francophone
Community radio stations are a new phenomenon in Nairobi, the capital of Kenya. While the Kenya Communications (Amendment) Act 2008 recognizes them as a media category, confusion remains around questions of ownership, funding and roles. Following the volatile post-election situation of December 2007, the government imposed a month-long live media ban. Media has been blamed by politicians for infla
In spite of the modernization of obstetrics in Tamil Nadu, the rural women still adhere to several traditional beliefs and practices, in regard to childbearing and postpartum. The varieties of non-biomedical practices were used in attempt to ensure a risk-free delivery and the birth of a healthy baby, although the collected data shows that some of them are harmful. To understand why the rural wome
This study examines and compares theoretical CDS spreads created by a structural framework with empirical CDS spreads. The model employed is the CreditGrades model based on the Merton framework from 1974 which calculate default probabilities and credit spreads from balance sheet and equity data. The aim is to measure how well the model can explain the observed CDS spreads and if it has any predict
This paper empirically discusses the interaction between Chinese Official Development Assistance (ODA) and Sub-Saharan tax revenue 2000-2017. Through the use of the methods OLS and IV, I pose the question whether there is evidence supporting the tax-aid nexus, which suggests a negative impact of increasing foreign aid on tax revenue. Additionally, the research delves into the specific effects of O
The usage of yeast in conventional brewing techniques involving alcoholic fermentation is an age-old process. Analyzing the viability and obtaining physiological information regarding the microbial diversity of the fermentation samples plays a pivotal role in obtaining real-time information as well as developing a more efficient process design. While traditionally, methods like methylene blue cell
This thesis aims to analyze the relationship between growth in CO2 per capita and growth in GDP per capita and whether they can grow in different directions- a concept referred to as eco-economic decoupling. By using the latest data and an extensive dataset with econometric analysis techniques, the thesis shows that while there currently is no absolute decoupling - global, economy-wide, and durabl
Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for
This study investigates what impact Fairtrade has on labour and human rights development in the Kenyan cut flower industry, by discerning developments and comparing conditions between Fairtrade and non-Fairtrade farms. The developments sustainability and Fairtrade in relation to previous research is also brought up and discussed. The study is mainly based on interviews with people knowledgeable ab
The purpose of this paper is to evaluate international counterterrorism efforts to estimate their costs and potential adverse effects over time. An underlying presumption of the study is that flawed counterterrorism measures to some extent are counterproductive, and building on this idea a comparison is made between the distinguishing features of the 'War on Terror' and an alternative mode
By conceiving identity as endogenously defined and construing other central political concepts according to this assumption, constructivism has proven apt to understand and explain phenomena that eariler were hard to grasp. Constructivist ideas have here been used in order to analyze the events surrounding the Single European Act as a contrast to the more conventional rationalist approach used by
The Big Tech companies, more precisely the five American giants: Google, Apple, Facebook, Amazon and Microsoft, have been performing a massive number of startup acquisitions and strengthening their dominant position in the market. In an economical study about mergers in the pharmaceutical sector the term killer acquisition was firstly adopted to define a transaction in which an incumbent, after ac
This thesis addresses the challenge of transforming car-oriented, mono-functional big-box landscapes into multi-functional, walkable local-centre. It assembles an integrated framework from recent research and translates it into a design approach to be tried in a case study. In contrast to the proposed multi-functional approach, a monocentric urban system concentrates functions and advantages in
Modern cellular radio base stations (RBS) employ beamforming to dynamically steer radio frequency (RF) energy toward active users. This adaptive transmission produces significant angular and temporal variations in the equivalent isotropically radiated power (EIRP). To account for these variations, electromagnetic field (EMF) compliance assessment of RBSs rely on the usage of the EIRP envelope toge
This article explores meaningful work across two frontline occupations, bank advisors and schoolteachers. We build on narrative research focusing on the role of stories and storytelling in the sensemaking and identity construction processes related to work to explore the importance of others in the perception and construction of everyday work as meaningful. To study this, we examine the narrativ
This thesis investigates subspaces of the Hardy space, especially ones defined via analytic continuation, and their applications to operator theory. The main function theoretic properties investigated are the distribution of zeros and extremal functions. The operator theory investigations are centered around the concept of invariant subspaces and cyclic vectors.
