Sommario/riassunto |
|
Eating Apes is an eloquent book about a disturbing secret: the looming extinction of humanity's closest relatives, the African great apes-chimpanzees, bonobos, and gorillas. Dale Peterson's impassioned exposé details how, with the unprecedented opening of African forests by European and Asian logging companies, the traditional consumption of wild animal meat in Central Africa has suddenly exploded in scope and impact, moving from what was recently a subsistence activity to an enormous and completely unsustainable commercial enterprise. Although the three African great apes account for only about one |

|
percent of the commercial bush meat trade, today's rate of slaughter could bring about their extinction in the next few decades. Supported by compelling color photographs by award-winning photographer Karl Ammann, Eating Apes documents the when, where, how, and why of this rapidly accelerating disaster. Eating Apes persuasively argues that the American conservation media have failed to report the ongoing collapse of the ape population. In bringing the facts of this crisis and these impending extinctions into a single, accessible book, Peterson takes us one step closer to averting one of the most disturbing threats to our closest relatives. |

Sommario/riassunto |
|
The 34 chapters of the 2nd edition of How to Gain Gain give a detailed insight into a collection (54) of the most common gain producing, constant current generating possibilities, and electronic noise creation of triodes for audio pre-amplifier purposes. These chapters also offer complete sets of formulae to calculate gain, frequency and phase responses, and signal-to-noise ratios of certain building blocks built-up with this type of vacuum valve (tube). In all cases detailed derivations of the gain formulae are also presented. All what is needed are the data sheet valve characteristic figures of the triode's mutual conductance, the gain factor and the internal plate (anode) resistance. To calculate frequency and phase responses of gain stages the different data sheet based input and output capacitances have to be taken into account too. To calculate transfer functions and signal-to-noise ratios for any kind of triode driven gain stage, including all its bias setting, frequency, phase, and electronic noise influencing components, example Mathcad 11 worksheets as an essential simulation tool for each chapter allow easy follow-up and application of the respective formulae. Free download of all worksheets is guaranteed from the editor's web-site. |
