The book explores the opto-electronic properties of three novel carbazole-based co-polymers designed for use in phosphorescent polymer light-emitting diodes. It details the absorption, steady-state, and time-resolved emission spectroscopy of these conjugated polymers, highlighting key findings such as optical band-gaps, transition energies, and Stoke's shifts. The study reveals significant insights into decay kinetics, with triplet excited state lifetimes varying from several milliseconds at low temperatures to under 3 milliseconds at room temperature, alongside observations of delayed fluorescence.

The research explores financial leverage and associated risks, focusing on financial risk disclosure practices among publicly traded manufacturing companies in Bangladesh. As a pioneering study in a developing country context, it aims to enhance understanding of capital structure and financial risk disclosure. The findings are intended to support the development of a robust capital market and contribute to the overall economy of Bangladesh by addressing the needs of various stakeholders and regulators.

The study explores the radiation pressure force on non-spherical dust particles, specifically water ice, magnetite, and silicate, using the Discrete Dipole Approximation method. It examines how solar radiation and solar wind pressures influence solid bodies ranging from 0.1 m to 100 m in the interplanetary space, particularly focusing on the early solar system when the solar wind pressure was stronger than radiation pressure. The research highlights the dominance of the pseudo-Poynting-Robertson effect during this period, emphasizing the complex interactions between solar forces and dust particles.

The protagonist draws inspiration from a rich tapestry of personal experiences and a deep appreciation for comic books, especially those by Harvey Pekar and Robert Crumb. His passion for Art Deco architecture and admiration for historical artists like John Martin and Winsor McCay shape his creative vision. A notable aspect of his work is the commitment to philanthropy, with 70% of proceeds from his art directed towards non-profit organizations in Canada and Bangladesh, while the remainder supports the purchase of art materials.

Die Untersuchung bietet eine umfassende Analyse der finanziellen Hebelwirkung und der damit verbundenen Risiken sowie der Offenlegungspraktiken in börsennotierten Produktionsunternehmen in Bangladesch. Sie stellt eine bahnbrechende Studie dar, die das Verständnis der finanziellen Risikodokumentation in einem Entwicklungsland vertieft. Die Ergebnisse tragen zur bestehenden Literatur über Kapitalstruktur und Risikotransparenz bei und fördern die Entwicklung eines effizienten Kapitalmarktes in Bangladesch, indem sie den Bedürfnissen von Interessengruppen und Regulierungsbehörden Rechnung tragen.

Este estudo pioneiro analisa a alavancagem financeira e os riscos associados nas empresas de produção cotadas no Bangladesh, focando na divulgação de riscos financeiros. As conclusões visam enriquecer a literatura sobre estrutura de capital e apoiar o desenvolvimento de um mercado de capitais eficiente no país.
