Bitron C the newest revolution among UVClarifiers with the highest level of efficiency thanks to an even longer water dwell time (time in which the water is in contact with UV Light). Irradiation times are regulated automatically and thus energy costs are
From the ancient origins of astronomy to the Copernican revolution, and from Galileo to Hawking's research into black holes, The Story of Astronomy charts the discoveries made by some of the greatest minds in human history, and their attempts to unveil the secrets of the stars. Written in an accessible and entertaining style, The Story of Astronomy demystifies some of the biggest breakthroughs in the history of science, as well as explaining why we have 60 minutes in an hour, how the Romans bodged the invention of the leap year and when people really discovered the Earth wasn't flat (a thousand years before Columbus. In the most straightforward and compelling of ways Peter Aughton demonstrates the beauty and wonder of what Newton, Einstein, Hubble and Hawking really achieved.
SiGe HBTs is a hot topic within the microelectronics community because of its applications potential within integrated circuits operating at radio frequencies. Applications range from high speed optical networking to wireless communication devices. The addition of germanium to silicon technologies to form silicon germanium (SiGe) devices has created a revolution in the semiconductor industry.These transistors form the enabling devices in a wide range of products for wireless and wired communications. This book features: SiGe products include chip sets for wireless cellular handsets as well as WLAN and high-speed wired network applications Describes the physics and technology of SiGe HBTs, with coverage of Si and Ge bipolar transistors Written with the practising engineer in mind, this book explains the operating principles and applications of bipolar transistor technology. Essential reading for practising microelectronics engineers and researchers. Also,optical communications engineers and communication technology engineers. An ideal reference tool for masters level students in microelectronics and electronics engineering.
Arresting...intellectually satisfying....Reveals a curious and previously hidden history of sex in America, in which scientific theories offered seemingly rational foundations for sexual abstinence, while religion, for once, gave us the nod of cosmic approval"-- Psychology Today . This provocative book shows how Christianity has shaped Americans' sexual expectations--and laid the foundations for the sexual revolution.
