Maternal smoking during pregnancy has been reported to negatively impact sperm counts of the sons. Sufficient data on the effect of paternal smoking is lacking.

Laminar burning velocities of four biomass derived gases have been measured at atmospheric pressure over a range of equivalence ratios and hydrogen contents, using the heat flux method on a perforated flat flame burner. The studied gas mixtures include an air-blown gasification gas from an industrial gasification plant, a model gasification gas studied in the literature, and an upgraded landfill g

Parkinson’s disease (PD) is considered one of the most frequent neurodegenerative disorders amongst elderly people. PD leads to loss of dopaminergic neurons in substantia nigra of the brain giving symptoms such as slowness of movement and dementia. PD brains have been found to contain accumulations of a protein named alpha‐synuclein (α‐syn). Additional to its aggregation propensity in PD it is als

Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster. Theoretical studies have indicated that some of these clusters can

Biomolecular condensates are aggregates formed from liquid-liquid phase separation through the interactions between nucleic acids and multivalent proteins. These condensates are essential for many biochemical processes inside the cell. Therefore, there has been a large effort during the last decade to create models and methods to describe these systems. Mixtures of RNA and proteins are very common

The world is slowly moving towards a more environmentally friendly mindset and many companies, such as Tetra Pak® have followed this lead by producing more environmentally friendly products and developing better materials with less environmental impact. To accommodate these requirements, it is important that the package is recyclable. For a carton this is defined by the repulpability, i.e., the ab

Myths, religious beliefs, and symbols are crucial components of ethnicity. PKK as a nationalist separatist armed organization- intensively uses them to construct a Kurdish identity which is compatible with its ideology as well as its objectives to mobilize Kurds and to galvanize their support. This thesis seeks to describe how PKK –as a militant organization- has instrumentalised Islamic related t

Purpose: even in the era of exponential increase in the amount of stellar data gathered, binaries are still often overlooked in observational data due to the special handling they require. The goal of this work is to develop a method capable of automatically and efficiently identifying and extract double-lined spectroscopic binaries (SB2) from a spectroscopic survey, while being scalable and techn

Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. Large surveys are up and coming, and several surveys are already working, and with these, the aim is high quality abundance measurements of several ele

The initial mass function (IMF) describes the stellar mass distribution for a population of stars at birth. This parameter represents a topic of long standing discussion within astronomy due to its apparent insensitive nature to environmental conditions. However, in the last decade, significant evidence suggesting the contrary has been presented. Due to the role of the IMF as an input variable for

Despite the fact that a great majority of experts predicted that religion would lose its power and influence, we are currently experiencing a worldwide revival of religious sentiments. The purpose of this study is to investigate how religion, politics, and security impact identity construction in France and Turkey. This study used critical discourse analysis and thematic narrative analysis to exam

Rheology is a science studying the flow, deformation and fracturing of a material. For a general understanding, this science is utilised to predict how a certain material will behave under certain conditions; in other words, the aim is the characterization of a material. (Wahlkrantz, 2020) This characterization is used to describe the elastic behaviour and the flow behaviour of a material. The ela

With the ambition to contribute to a sustainable development, this project started with aim to recycle fiber boards. The idea behind the project is to take lose fibers that come from waste product or simply just worn out fiber boards, and make them into new fiber boards. In order to achieve this, a binder is needed to hold the boards together. The aim of this thesis was to evaluate different binde

This thesis examines how the right of free movement and the borders are perceived and practiced by Europeans, and how they affect the everyday lives of Europeans in the context of the current refugee crisis and Paris attacks. It claims that EU, EEA, CH and the Schengen area constitute a cultural construction within Europe based on inclusion and exclusion, belonging and citizenship. The freedom of

Protoplanetary disks consist of matter in both gas and solid form. The sizes of the solid particles, dust grains, although in minority compared to the gas, are important in the formation of larger bodies such as planetesimals. This is a topic which has been widely explored. However, the impact of the dust grain sizes on the underlying disk structure has not yet been as extensively modeled. Differe

The current Lambda Cold Dark Matter cosmology predicts galaxy growth by hierarchical merging, leading to galaxy substructure like tidal streams and dark matter subhalos devoid of stars. The goal of this thesis is to investigate whether tidal stream-subhalo interactions can leave observable gaps in the streams, and at which rate this might happen in a galaxy like the Milky Way. The stream-subhalo i

Over the past two decades many discoveries of exoplanets have been made, which have drawn much attention to extrasolar planetary systems. In this work we study the composition of these systems and search for analogues of the Solar System. We considered the planets in the database at exoplanet.eu. The search of solar-like systems required these planets to be classified. The classification was perf
