Exposure of combined pollutants is as of today not a very well-researched field of environmental science due to the complex interactions that may occur. Nanoplastic particles (NP) in particular are lacking studies due to the relatively new interest in the subject. In this study, a small experiment in a lab environment was performed that observed the combined effects of polysterene NP and 17α-ethin
In this thesis we add a temperature dependence to the newly developed variable polytrope equation of state (Varpoly EOS) from Weppner et al. (2015), making it more universal and more applicable for planetary simulations. In this process we develop a new model for the Gruneisen parameter, which is a parameter that describes how pressure changes with the internal energy. This new model conforms to t
For testing three-dimensional (3D) hydrodynamic models of stellar atmospheres, spectroscopy across spatially resolved stellar surfaces with high spectral resolution is desired. 3D models predict center-to-limb changes in asymmetries, shapes, strengths and wavelength positions of spectral line profiles, reflecting the hydrodynamics of the stellar atmosphere. However, except for a few supergiants an
In the thriving field of exoplanet research new discoveries are made all the time, and while most of the observed systems can be explained with classical planet formation models - some are much harder to explain. When stars form they are often surrounded by the remaining material of the nebulae they formed from. Some of this remaining material forms into a protoplanetary disk around the protostars
In this project aperture photometry has been performed for stars in the direction of the dwarf spheroidal galaxy Leo II. The observations were carried out using the Stro ̈mgren filters v, b and y, during three consecutive nights in 2003, out of which all but the first one turned out to be non-photometric. The data was reduced and calibrated (using the metallicity calibration of Calamida et al. (20
The purpose of Galactic archaeology is determining the history of the Milky Way (MW) Galaxy. To do this one uses observational data from stellar populations in terms of properties such as kinematics, chemistry, ages, and evolution. In this context a population means stars with similar characteristics and the most notable population is “the Solar Neighbourhood” (SN). Stars orbit with a ‘guiding rad
The impact of climate change is increasingly being investigated over elevational gradients as they provide natural laboratories to study how species of plants and animals respond to changes in temperature, precipitation and other factors. Ferns are especially sensitive to air humidity and temperature and can therefore serve as potentially useful bioindicators. To better understand how species comm
This thesis evaluates the political focus of the Swedish and Finnish green parties by examining their election manifestoes since year 2000. This is investigated through a content analysis with a coding scheme based on theories and previous research about post-materialism and post-material political issues. The theory of Inglehart regarding post-material value change, from material focus to post-ma
Oil companies are powerful global actors and are repeatedly accused of violence. Previous research on this topic is limited, however, and the thesis therefore set out to investigate the following question: What role do oil multinational corporations (MNCs) play as perpetrators of structural and slow violence in the areas where they operate? A comparative small-N design was applied, and two cases w
Although different types of affinity tags have become a tool in the production and purification of recombinant proteins in various applications, the use of these have the risk of interfering with the biological activity and crystallization of proteins.There are both chemical and enzymatic ways to remove these tags, the enzymes include enteropeptidase, thrombokinase and protease to mention a few. T
Lift force is a crucial factor in aviation, particularly during landing phases where maintaining optimal lift is essential for safety and performance. This thesis explores the effectiveness of suction and blowing control methods in enhancing aerodynamic performance and increasing lift force. By investigating these control techniques, the study aims to provide recommendations for practical applicat
Galectins are small soluble proteins that bind to carbohydrates. They have a high affinity for glycoconjugates containing galactose that exist naturally on the surface of cells and in the extracellular surroundings. This allows them to be involved in many different physiological and pathological process in the human body. Galectin-3, that is the focus in this report, works proinflammatory which no
Purpose: The purpose of this study is to investigate the existence of information asymmetry displayed in the initial return, and post-IPO financing. Additionally, how sponsor certification influences IPOs and in the post-IPO financing as a means to reduce information asymmetry. Methodology: The study was conducted based on a quantitative research method, followed by a deductive approach, which in
Background and objectives: Acute myeloid leukemia (AML) is the most common type of leukemia in adults with relatively high recurrence. Interferon alpha (IFNa) is a type I interferon and it has been shown to have a therapeutic effect on myeloid malignancies in clinical research especially to prevent potentially risky AML recurrence after chemotherapy. Due to the molecular heterogeneity of the disea
Several high resolution electrophysiological techniques such as measurements of cell membrane capacitance and amperometry are used to detect exocytotic events. A novel method was developed in this study based on the expression of P2X2 receptor channel in secreting cells. The presence of ATP sensitive channel on the cell membrane permitted the electrical detection of minute (amoles) quantities of A
Ethnologists like to think of themselves as masters of the study of the everyday, but we still know surprising little how this mundane machinery works. Everyday life remains something of a black box, our understanding is still piecemeal and fragmented. This paper explores cohabitation and circulation of objects, affects and activities in the home - seen as a workshop where raw materials, raw feeli
Multiple Sclerosis (MS) is a progressive autoimmune inflammatory and demyelinating disease of the central nervous system (CNS). T cells play a key role in the progression of neuroinflammation in MS and also in the experimental autoimmune encephalomyelitis (EAE) animal models for the disease. A technology for quantitative and 3 dimensional (3D) spatial assessment of inflammation in this and other C
This paper aims to provide a critical and systematic review of the societal costs of air pollutionrelated ill health (CAP), to explore methodological issues that may be important when assessing or comparing CAP across countries and to suggest ways in which future CAP studies can be made more useful for policy analysis. The methodology includes a systematic search based on the major electronic data
Co-digestion of food waste and green waste was conducted with six feedstock mixing ratios to evaluate biogas production. Increasing the food waste percentage in the feedstock resulted in an increased methane yield, while shorter retention time was achieved by increasing the green waste percentage. Food waste/green waste ratio of 40:60 was determined as preferred ratio for optimal biogas production
