Lee de Forest
The life-long inventor, Lee de Forest invented the three-element vacuum tube used between 1906 and 1916 as a detector, amplifier, and oscillator of radio waves. Beginning in 1918 he began to develop a light valve, a device for writing and reading sound using light patterns. While he received many patents for his process, he was initially ignored by the film industry. In order to promote and demonstrate his process he made several hundred sound short films, he rented space for their showing; he sold the tickets and did the publicity to gain audiences for his invention. Lee de Forest officially brought sound to film in 1919. Lee De Forest: King of Radio, Television, and Film is about both inve...
Forest Genomics and Biotechnology
Developments in genomics and biotechnology are opening up new avenues for accelerating the domestication of forest trees in a climate change-driven world. This book presents an authoritative update of forest tree biotechnology and genomics methodologies, procedures and accomplishments, from basic biological science to applications in forestry and related sciences. It gives expert evaluation of achievements and discussion about the impact that novel forest biotechnological and genomics approaches are having on traditional breeding for improvement of forest tree species and production of forest-based products. It also describes the legal and regulatory aspects of forest biotechnology, with an emphasis on biosafety. It is a reference for forest biologists, including basic and applied scientists involved in forest tree breeding and biotechnology, bioenergy research, biomaterial product development. It is a comprehensive text for graduate-level students in the areas of Plant Biology and Forest Genetics, Silviculture and Agroforestry, and Bioenergy Science and Technology.

Photonic, Electronic And Atomic Collisions - Proceedings Of The Xxiv International Conference
This volume contains contributions covering a wide range of subjects in the area of photonic, electronic and atomic collisions. These include the collisions of heavy particles and electrons with atoms, molecules and clusters; the coherent control of reaction dynamics using lasers and electromagnetic fields with molecules, clusters and liquids; recent experimental progress in the synthesis of antihydrogen; the interaction of solar winds with cometary atmospheres, and the physical interpretation of reactions in biological systems./a
