The classic of Stalinist aberrant genetic theory, horticulturist Lysenko rejected orthodox genetics in favor of the theories of those of the Russian horticulturist I. V. Michurin (d. 1935). Among his theories were that wheat raised under certain conditions produce seeds of rye and that theoretical biology must be fused with Soviet agricultural practice. He was the total autocrat of Soviet biology from 1948 through 1953, and believed that through inherited characteristics Stalinism would create a ’new man’. Lysenko held that heredity can be changed by husbandry, a theory that had d

Rivers differ among themselves and through time. An individual river can vary significantly downstream, changing its dimensions and pattern dramatically over a short distance. If hydrology and hydraulics were the primary controls on the morphology and behaviour of large rivers, we would expect long reaches of rivers to maintain characteristic and relatively uniform morphologies. In fact, this is not the case - the variability of large rivers indicates that other important factors are involved. River Variability and Complexity presents an interesting approach to the understanding of river vari

Blazars (also known as BL Lac objects), first discovered in 1978, are unusually energetic objects in the extragalactic universe. About 200 are known or suspected. They are radio sources with highly variable optical and radio emission, as well as high polarization, and their optical spectra normally have no distinguishable features. It is generally accepted that they belong to that class of galaxies with active galactic nuclei, which are presumed to be driven by infall of matter to a supermassive black hole. In this book researchers give a complete summary of the observations of blazars and

Can renewable energy provide reliable power? Will it need extensive backup?The energy available from wind, waves, tides and the sun varies in ways that may not match variations in energy demand. Assimilating these fluctuations can affect the operation and economics of electricity networks. Is this a significant problem, or can these new sources be integrated into the grid system without the need for extensive backup or energy storage capacity?This book examines the significance of the issue of variability of renewable electricity supplies, and presents technical and operational solutions to th
