The stability of DNA in solution and the phase behavior in mixtures with dodecyltrimethylammonium bromide (DTAB) were investigated. By means of circular dichroism, UV absorption, and differential scanning calorimetry, we found that for dilute solutions of DNA with no addition of salt the DNA molecules are in the single-stranded conformation, whereas the addition of a small amount of NaBr, 1 mM, is

The PITX family of transcription factors regulate the development of many organs. Pitx1 mutants have a mild pituitary phenotype, but Pitx2 is necessary for the development of Rathke's pouch, expression of essential transcription factors in gonadotropes, and expansion of the Pit1 lineage. We report that lack of Pitx2 causes the pouch to undergo excessive cell death, resulting in severe pituitary hy

Thermoresponsive colloidal microgels expel solvent from their interior upon crossing a threshold temperature, resulting in a significantly reduced size. The collapse of microgels can reversibly switch the interparticle interactions from soft repulsive to attractive, and the accompanying size reduction allows for precise control over volume fraction. Mixing two microgels that collapse at different

Metal halide perovskites are an important class of emerging semiconductors. Their charge carrier dynamics is poorly understood due to limited knowledge of defect physics and charge carrier recombination mechanisms. Nevertheless, classical ABC and Shockley-Read-Hall (SRH) models are ubiquitously applied to perovskites without considering their validity. Herein, an advanced technique mapping photolu

This study discusses IKEA's brand storytelling across its official websites and Chinese social media platforms, with a focus on the balance between consistency and localisation in its brand narratives on the Swedish and Chinese official websites, as well as the expression of local adaptation in the brand's official accounts on Xiaohongshu and Weibo. Through multimodal social semiotic analy

China employs approximately half of the world's coal workers while also implementing one of the world's largest decarbonization programs. This thesis examines how official policy discourse constructs the social costs of coal transition, focusing on how coal workers and transition-related burdens are framed, recognized, and governed in official policy texts. The study uses Critical Discours

The aim of this study is to bring further understanding to the contested relationship between development aid and democracy. By introducing quality of democracy as an alternate measure to the ones previously used, the ambition is to approach the subject from a new perspective. In this thesis, the following research question will be answered: To what extent does Official Development Assistance (ODA
