When the first sputnik was launched and the space era began, few
gave thought to the possible negative impact of putting satellites
into orbit. In fact, man's space activity has led to the formation
of a new media named "space debris," i.e. man-made objects and
their fragments launched into space, currently inactive and no
longer serving any useful purpose. Space Debris: Hazard Evaluation
and Mitigation will appeal to readers unfamiliar with the issues,
as well as experts and designers. It introduces concepts behind the
problems of space ecology. The volume features actual data on the
space debris environment; new mathematical models for space debris
evolution, production and self-production; description of the
existing software and concepts for shield design. The author also
reviews methods of collision risk assessment, including the
attitudes and inclinations of orbits, collision hazard evaluation
and suggestions for preventative measures.

Space Debris: Hazard Evaluation and Mitigation will be of interest to readers unfamiliar with the issues as well as experts and designers as it introduces concepts related to the problems of space ecology featuring actual data on the space debris environment, new mathematical models for space debris evolution, production and self-production, description of the existing software, and concepts for shield design. Methods of collision risk assessment depending on attitudes and inclinations of orbits, collision hazard evaluation and suggestions for preventative measures are also covered.
Many western limnologists have no or a very limited knowledge and
understanding of limnology in the Soviet Union; the language
barrier is simply too hermetic, and the threshold for making the
effort (and spending the money) for obtaining translations of
significant Russian works is usually too high for most Eu ropeans
and North Americans. There is so much to read aside from that
literature printed in the cyrillic al phabet that, not by intention
or by design, but by sheer inertia, we tend to forget about it
altogether. Of course, we are wrong, and we know it. Today,
'Hydrobiologia' is proud to present a theme volume by one of the
active Soviet limnologist groups, ably steered by Nikolai Smirnov.
Their target lake, Glubokoe ozero, is one of the better studied
waters of the northern hemisphere, and the series of contributions
included in this collection of papers aims both at illustrating
this point and at making this interesting material widely available
in a congress language. I am confident that 'Studies on Lake
Glubokoe' will make a significant contribution to a well-merited
better penetration of Russian science onto the world market. H. 1.
