This book traces the fascinating history of the first Polish gay and lesbian magazines to explore the globalization of LGBT identities and politics in Central and Eastern Europe during the twilight years of the Cold War. It details the emergence of homosexual movement and charts cross-border flows of cultural products, identity paradigms and activism models in communist Poland. The work demonstrates that Polish homosexual activists were not locked behind the Iron Curtain, but actively participated in the transnational construction of homosexuality. Their magazines were largely influenced by Western magazines: used similar words, discussed similar topics or simply translated Western texts and reproduced Western images. However, the imported ideas were not just copied but selectively adopted as well as strategically and creatively adapted in the Polish magazines so their authors could construct their own unique identities and build their own original politics.
Polymer Engineering focuses on the preparation and application of polymers in several hot topics such as artificial photosynthesis, water purification by membrane technologies, and biodiesel production from wastewater plants. The authors not only describe the latest developments in polymer science, but also support these experimental results by computational chemistry and modelling studies.
Technological development enhances the demand for new sources of white lighting characterized by low energy consumption, high emission efficiency and low production costs. Therefore much effort is concentrated on the development of new, more effective and easier synthesis methods of phosphors, new phosphor projection and technological solutions. This book presents an up-to-date examination of how phosphors are used for laser-induced solid state lighting as well as describing the phenomena that are responsible for interionic energy transfer leading to light generation. The phenomena cover all significant effects which have to be taken into account in case of phosphors for laser induced lighting. These include: concentration effect, size effect and thermal conductivity on luminescent properties of phosphor for lighting. Chapters describe both conventional Stokes emission and also down-converting and up-converting anti-Stokes phosphors. The mechanisms of generation of broad band emission are also covered. Covering the luminescent properties and applications of phosphors, the book suggests possible directions for future research, in order to produce new efficient phosphor for lighting. It will be extremely valuable for researchers seeking an overview of current trends in laser induced lighting, highlighting current research, and explaining phenomena that are responsible for light generation in phosphors. Moreover, this book is an important reference which describe the phenomena that need to be taken into account when preparing new phosphor for laser induced solid state lighting. Examination of the size effect of phosphor grain on its luminescent (up- and down-convertion) properties, allowing scientists to use phosphor grain more effectively Detailed information of thermal conductivity at the nanoscale and its influence on luminescent properties Explains how phosphors are used for laser induced lighting, allowing readers to exploit phosphors to their full potential
