In the oil and gas industry, technologies have been developed to address microbial-related issues such as oil field souring, microbiologically influenced corrosion, biofouling, and targeted measures for risk assessment and mitigation. Microorganisms have also benefited the oil sector through microbial-enhanced oil recovery and bioremediation of petroleum-contaminated environments. However, duri…
This book does not deal with all forms of dance equitably; it is primarily about the movements of classical ballet, not because of a judgment as to the inherent value or worth of that style of dance, but because of the relatively well defined and accepted “vocabulary” of movements and positions. Although there are variations in the style with which balletic movements are carried out by diff…
In April 1933, at a small gathering at a meeting of the US National Committee of the International Scientific Radio Union (URSI), Bell Labs scientist Karl Guthe Jansky announced that he had detected 20.5 MHz (14.6 m) radio emis-sion from the Milky Way. Jansky used a novel directional antenna based on an invention by AT&T Bell Labs colleague, Edmond Bruce, that rotated every…
The subject of this book is modern electronics, a field that has come to be known as microelectronics. Microelectronics referes to the integrated-circuit (IC) technology that at the time of this writing is capable of producing circuits that contain more than 1 million components in a small piece of silicon (silicon chip) whose area is in the order of 60 mm2. We shall study electronic devices th…
The Mole had been working very hard all the morning, spring-cleaning his little home. First with brooms, then with dusters; then on ladders and steps and chairs, with a brush and a pail of whitewash; till he had dust in his throat and eyes, and splashes of whitewash all over his black fur, and an aching back and weary arms. Spring was moving in the air above and in the earth below and arou…
