Based on actual data of Soviet whaling, and reliable methodologies that existed at the time when this monograph was written, it examines the distribution and migration patterns of whales of the Southern Ocean. It defines distinct populations on the basis of phenes, as well as whale breeding zones, which are located in the adjacent to the Southern Ocean waters at lower latitudes. The book records the presence of a new species of killer whale in the Southern Ocean - Orcinus nana. Prenatal growth patterns, pregnancy and lactation duration, mean sizes of new-born whales are determined. Methods for the graphic recording of registering structures are described, and an original method for their decoding is proposed to determine animal age. The age of sexual and physical maturity, life expectancy is determined. Earlier unknown “pair formations” on the lower jaw of baleen whales and sperm whales are described, together with their macro, histological and electronic microscopic structure. The impact of the extermination of whales on the Southern Ocean ecosystem is examined, recommendations for control of the current state of whale populations are given, and perspectives of whale population recovery are estimated. Regions that could be used as testing areas for whale registration method are defined. The book is intended for biologist-cytologists, ecologists and other specialists interested in cetaceans, and for biology students.
This updated edition of a classic title studies identical relations in Lie algebras and also in other classes of algebras, a theory with over 40 years of development in which new methods and connections with other areas of mathematics have arisen. New topics covered include graded identities, identities of algebras with actions and coactions of various Hopf algebras, and the representation theory of the symmetric and general linear group.
For over five hundred years the Russians wondered what kind of people their Arctic and sub-Arctic subjects were. "They have mouths between their shoulders and eyes in their chests," reported a fifteenth-century tale. "They rove around, live of their own free will, and beat the Russian people," complained a seventeenth-century Cossack. "Their actions are exceedingly rude. They do not take off their hats and do not bow to each other," huffed an eighteenth-century scholar. They are "children of nature" and "guardians of ecological balance," rhapsodized early nineteenth-century and late twentieth-century romantics. Even the Bolsheviks, who categorized the circumpolar foragers as "authentic proletarians," were repeatedly puzzled by the "peoples from the late Neolithic period who, by virtue of their extreme backwardness, cannot keep up either economically or culturally with the furious speed of the emerging socialist society."Whether described as brutes, aliens, or endangered indigenous populations, the so-called small peoples of the north have consistently remained a point of contrast for speculations on Russian identity and a convenient testing ground for policies and images that grew out of these speculations. In Arctic Mirrors, a vividly rendered history of circumpolar peoples in the Russian empire and the Russian mind, Yuri Slezkine offers the first in-depth interpretation of this relationship. No other book in any language links the history of a colonized non-Russian people to the full sweep of Russian intellectual and cultural history. Enhancing his account with vintage prints and photographs, Slezkine reenacts the procession of Russian fur traders, missionaries, tsarist bureaucrats, radical intellectuals, professional ethnographers, and commissars who struggled to reform and conceptualize this most "alien" of their subject populations.Slezkine reconstructs from a vast range of sources the successive official policies and prevailing attitudes toward the northern peoples, interweaving the resonant narratives of Russian and indigenous contemporaries with the extravagant images of popular Russian fiction. As he examines the many ironies and ambivalences involved in successive Russian attempts to overcome northern—and hence their own—otherness, Slezkine explores the wider issues of ethnic identity, cultural change, nationalist rhetoric, and not-so European colonialism.
The aim of the series is to present new and important developments in pure and applied mathematics. Well established in the community over two decades, it offers a large library of mathematics including several important classics. The volumes supply thorough and detailed expositions of the methods and ideas essential to the topics in question. In addition, they convey their relationships to other parts of mathematics. The series is addressed to advanced readers wishing to thoroughly study the topic. Editorial Board Lev Birbrair, Universidade Federal do Ceará, Fortaleza, Brasil Victor P.

This book explores many mysterious features of the structure and evolution of the Earth’s continents, still unknown to the scientific community and a wider audience. Science has now proved that the southern continents of South America, Africa and Australia represent the southern ends of a single three-beam megacontinent. It began to form 4.4 billion years ago in a huge three-beam cavity on the planet’s surface and grew vertically up to its present state. Proof of the reality of a single three-beam megacontinent is a fundamental discovery in Earth sciences, and represents a new level in the understanding of the planet’s structure. The text will appeal to researchers of Earth sciences, university teachers and students, and secondary school teachers of geography and geology, as well as all readers with an interest in the history of our planet.
A. N. Parshin is a world-renowned mathematician who has made significant contributions to number theory through the use of algebraic geometry. Articles in this volume present new research and the latest developments in algebraic number theory and algebraic geometry and are dedicated to Parshin's sixtieth birthday. Well-known mathematicians contributed to this volume, including, among others, F. Bogomolov, C. Deninger, and G. Faltings. The book is intended for graduate students andresearch mathematicians interested in number theory, algebra, and algebraic geometry.
