Heavy metals are severe environmental pollutants, and many of them are toxic even at very low concentrations. With industrial development, soil pollution with heavy metal elements have dramatically increased. The uptake of heavy metals via plants that are exposed to contaminated soils is a risk for human health and a major hazard for the ecosystem as a whole, including soil microorganisms. On the other hand, plants may be used in the decontamination of soils. The topics presented in this book include: sources of heavy metals contaminants in soils; plant species that can grow on contaminated soils; the phytoremediation of contaminated soils; tolerance, accumulation and detoxification mechanisms of zinc, copper, arsenic, cadmium and vanadium in plants; the critical role of sulfur metabolism in heavy metal tolerance; the role of aquatic macrophytes, plant growth-promoting bacteria, sugar crops and earthworms in detoxification; and heavy metal stabilization by promoting zeolite synthesis in soils.
Photosynthesis is the process by which plants, algae and certain species of bacteria transform solar energy into chemical energy in the form of organic molecules. In fact, all life on the planet ultimately depends on photosynthetic energy conversion. The book provides a compressive and state-of-the-art of very recent progress on photosynthesis research. The topics span from atom to intact plants, from femtosecond reactions to season long production, from physics to agronomy. The book is to offer advanced undergraduate students, graduate students, and research specialists the most recent advances in the all aspects of photosynthesis research. The book is intended to offer researchers detailed information on the most recent advances in all aspects of photosynthesis research.

Kolejna – po Czarnym mercedesie – wspaniała powieść mistrza pióra! Ruszyła także produkcja serialu na podstawie obu powieści. Nadkomisarz Rafał Król ucieka przed gestapo do Lwowa. Ma nadzieję zatrzymać się u Lenki, prostytutki, która dorabia jako biuralistka w Ratuszu. Niestety, Lenka parę dni wcześniej zniknęła. Dowiaduje się przy okazji, że Lenkę nachodził jakiś Ukrainiec. I że nie prezentował się specjalnie przyjaźnie. Kiedy Król jedzie do Molendowej, wdowy, którą znał z dawnych lat, zastaje zgliszcza. Molendowa nie żyje. I nie był to wypadek. Rafał Król zaczyna śledztwo. Chce przede wszystkim odszukać zaginioną Lenkę i dopaść podejrzanego Ukrai...
To mark the 800th anniversary of the ratification of the Magna Carta by King John at Runnymede, Magna Carta provides the central European perspectives on this monumental document and its impact on the political and legal experiences of freedom, from the medieval period to the present day. The volume gives rise to a discussion about the legacy of the Magna Carta as one of the fundamental elements of European identity. Supported by previously untranslated sources at the end of each chapter, the team of contributors consider the lasting legacy of Magna Carta in Hungary, the Czech Republic, Poland and Lithuania. The authors present the successful attempts to limit royal power by law while protec...
