An intriguing assortment of 30 complex 3-dimensional designs, this volume will appeal to colorists of all ages. Patterns range from closely interwoven squares, stars, and rectangles with sharp, angular forms, to flowing interlacements of circles, ovals, hearts, and other rounded shapes. The hypnotic images, some of which feature optical illusions, are absolutely fascinating.

The Second International Symposium on Three-Dimensional Electromagnetics was held at the University of Utah, Salt Lake City, in 1999. This symposium honors the memory of Gerald W. Hohmann, late Professor of Geophysics at the University of Utah, and follows the highly successful First Symposium held in Ridgefield, CT, organized in 1995 by Schlumberger-Doll Research (M. Oristaglio and B. Spies, Eds.). Nearly 25 years ago, Jerry published a seminal paper on EM scattering from 3-D structures in the earth due to diverse sources using the integral equation method 1. This achievement and the considerable body of subsequent work largely inspired by it, have shown how unique the behavior of fully 3-D structures can be. Very sadly, Jerry died May 23, 1992, at the age of 51 from complications of a cancer. His career history is described further in the citation for Honorary Membership in the Society of Exploration Geophysicists.

Evolving from years of teaching experience by one of the top experts in vegetation ecology, Data Analysis in Vegetation Ecology aims to explain the background and basics of mathematical (mainly multivariate) analysis of vegetation data. The book lays out the basic operations involved in the analysis, the underlying hypotheses, aims and points of views. It conveys the message that each step in the calculations has a specific, straightforward meaning and that patterns and processes known by ecologists often find their counterpart in mathematical operations and functions. The first chapters introduce the elementary concepts and operations and relate them to real-world phenomena and problems. Later chapters concentrate on combinations of methods to reveal surprising features in data sets. Showing how to find patterns in time series, how to generate simple dynamic models, how to reveal spatial patterns and related occurrence probability maps.

In the Aristotelian concept of the economic system, the economy served political goals. As far as these political goals were democratically legitimized, the economy directly served the people. The humanist credo of “man as the measure of all things” (Protagoras) led us to a free, liberal, and democratic world. However, the current global economic system more often than not treats humans as instruments for profits or GDP growth, ignoring the democratic rights and liberties they enjoy within their nation-states. The effects are injustice, environmental degradation, and unhappiness – even for those who currently profit from the existing system. To counter these inhumane effects, Humanistic Management Network creates and disseminates actionable knowledge that puts humans first and supports the creation of a life-serving economic system.

'Aero Modeller' (or Aeromodeller) was for decades the premier magazine for flying model aircraft. The first issue was dated November 1935. At its peak during the 1950s and 1960s it progessively absorbed a number of rivals, being called 'Aero Modeller now incorporating Model Aircraft' by February 1966, and 'Aero Modeller incorporating the Model Aeroplane Constructor and Model Aircraft' by 1968. Alongside the many features related to aeromodelling, each issue typically included one or two features on full-size aircraft. These usually centred around the famous series of scale plans for which the magazine was justly famous. Multi-part series such as 'Famous Biplanes' and 'Aircraft Described' ran across the centre pages and featured b+w photographs, detail sketches and a brief description alongside the multi-view scale drawings. In the early 1960s it also included a regular Q & A feature run by Air-Britain called 'Sign Post' which mostly concerned aircraft markings. This was later replaced by a series concentrating on aeromodelling. Some issues also included aircraft colour profiles on the inside back cover. During the 1960s the magazine averaged 38-44 pages per issue, with many b+w photos and line drawings and sketches.

Если можно говорить о подвижничестве применительно к военному человеку, то Роман Исидорович Кондратенко - герой обороны Порт-Артура - и был безукоризненным образцом воина-подвижника. Такими людьми на протяжении веков питался высокий боевой дух, патриотический потенциал русской армии. Такие, как он, неустанно формировали, проводили в жизнь незыблемые понятия о чести, мужестве, благородстве, находчивости русского солдата, офицера, полководца. Содержит фотоиллюстрации.
