The main purpose of this thesis is to present the seventeen classes of wallpaper groups. These are certain subgroups of the isometries of the plane, that preserve lattices. The concept of semidirect product will be introduced, since most of the wallpaper groups are constructed with this product, which is a generalization of the ordinary direct product of groups. Finally there is a part on the Pòly
MKBs way to manage and control the organisation is expressed through increased stewardship responsibilities. This responsibility implies that all individuals within the organisation takes responsibility and therefore becomes a part of the organisations success. The verbal communication is still the reason why MKB is successful as an organisation.

The fascinating molecular structure of indoline alkaloids, especially that of the communesins and perophoramidine (Figure 1), has encouraged the studies towards the total synthesis of the representatives of this alkaloid family, in particular perophoramidine. Finding methodologies to construct the vicinal quaternary stereocenters with the stereochemistry of perophoramidine is one of the main chall
Context: Data from the recently launched astrometric satellite Gaia will be coming in soon with the final data release expected in 2022. This will provide a very precise map of the Galaxy. The Solar system and Galaxy is thought to be filled with invisible bodies (planetesimals, planets, brown dwarfs, neutron stars, black holes, etc.) and they will affect the observations via gravitational lensing.
NADH:upiquinone oxidoreductase, or complex I, is the first and largest enzyme in the respiratory chain. It is the last known enzyme in the chain due to its complexity of being a very large complex comprising of a hydrophilic and a hydrophobic domains of about 46 subunits in total in the eukaryote enzyme. Another reason of its complexity is that the hydrophobic domain does not have any redox center
Polyphenols are a group of compounds that are widely spread in the plant kingdom. These compounds are of great interest for researchers because of their antioxidant properties that are important for both plant life and human health. Sample preparation is a crucial step for the determination of phenolic compounds and their metabolites in biological samples. Methods for isolation and preconcentratio
Two novel tetradentate ligands N, N’-Dimethyl-N, N’-bis(2-(chloromethyl)-1-methylbenzimidazole)- ethane-1,2-diamine (mepL), (-)-2-(((S)-2-((S)-1-(benzimidazol-2-ylmethyl) pyrrolidin-2-yl) pyrrolidin-1-yl)methyl)benzimidazole (PDPL) and their iron complexes [Fe(mepL)(CH3CN)2](SbF6)2 (SbF62), [Fe(CF3SO3)2(PDPL)] (OTf1) and [Fe(PDPL) (CH3CN)2](SbF6)2 (SbF61) were synthesized and characterized with IR
When designing control systems for real applications, it is important to first do testing in a simulated environment, to ensure adequate performance. This is especially important when designing control systems for applications that have high operation costs, e.g., submarines, since late errors in the development can be extremely costly. Saab develops steering systems for submarines. Prior to this
The origin of the class of exoplanets typically referred to as hot Jupiters is to this day an unsettled matter. Some of the proposed formation channels predict certain values of the spin-orbit misalignment parameter, i.e. the angle between the stellar rotation axis, and the angular momentum vector of the planet orbit. One such formation channel is tidal capture following Kozai resonance (TCKR). Th
Every year hundreds of thousands of Central American migrants from mainly Honduras, Guatemala and El Salvador embark on a journey through Mexican territory with the hopes of a better future in the United States - estimations suggest that up to thirty percent are women. Transnational migration is due to heightened violence in Central America on the rise. Although earlier research about women´s part
High levels of stress have been documented to impact memory and attention. On the other hand according to previous literature low levels of stress can be helpful in preparing individuals physically and mentally to become active. Relaxation techniques have been proved to reduce stress successfully but there is debate regarding if they have the same positive effects on cognitive performance as well.
Föreliggande studie har undersökt psykologyrkets inverkan på privatlivet, samt hur psykologer skiljer mellan det privata jaget och jaget i rollen som psykolog. Ett delsyfte var att få fördjupad förståelse för vilka föreställningar och förväntningar som psykologrollen inbegriper. Det finns få tidigare studier inom ämnet varför en explorativ ansats har valts. Semistrukturerade intervjuer genomfördesThe aim of the present study was to examine how working as a psychologist can affect the private life and how psychologists manage to separate the private self from the self in the role of the psychologist. A secondary aim was to explore ideas and expectations on the role of a psychologist. There were few prior studies in the area why an explorative approach was chosen. Semi-structured interviews
The shape of a diffuse reflectance spectra can provide knowledge about tissue composition. By analysing this spectra one can, with the right evaluation methods, find out information about the tissue. With known absorption properties of the present tissue chromophores it is possible, with a curve fit algorithm, to find their volume fractions in any measured tissue. In this work, the usability of
The aim of this paper was to explore the perceptions and images of mental illness that is conveyed in the media form of internet magazines, more precisely in the discussion forums that are found below the articles. This paper also explored how the category of people with mental health problems related to these structures. A central focus was to investigate how the image was constructed from the ta
