The past one year and a half has been a period of unprecedented changes for
the media industry in the Arab world and elsewhere. Within a short period of
one year since the release of the second edition of the Arab Media Outlook, the
contours of the world economy underwent transformations that shocked even
the most pessimistic observers. The media could not have remained unaffected
by such a cataclysmic turn of events.
urs is essentially a tragic age, so we refuse to take it tragically. The cataclysm has happened, we are among the ruins, we start to build up new little habitats, to have new little hopes. It is rather hard work: there is now no smooth road into the future: but we go round, or scramble over the obstacles. We’ve got to live, no matter how many skies have fallen. This was more or less Constance Chatterley’s position. The war had brought the roof down over her head. And she had realized that one must live and learn. She married...
Our knowledge of mass transfer processes has been extended and applied to various fields of science and engineering including industrial and manufacturing processes in recent years. Since mass transfer is a primordial phenomenon, it plays a key role in the scientific researches and fields of mechanical, energy, environmental, materials, bio, and chemical engineering. In this book, energetic authors provide present advances in scientific findings and technologies, and develop new theoretical models concerning mass transfer....
Traditionally astrophysics has concerned itself with minimum time-scales measured
in hours rather than seconds. This was understandable as the available recording
media were slow; e.g. chart recorders and photographic plates. In the 1950s, 60s
and 70s wavebands away from the optical were developed; from ground based
radio studies to space and balloon borne high energy work. In contrast to optical
wavelengths instrumentation in these (high and low energy) regimes was capable
of time resolutions of less than a second....
As new species emerged and evolved into disparate new forms, other species
became extinct. And just as the origin of species and disparity form large-scale
patterns, extinctions have formed patterns of their own. One of those patterns is
illustrated in . It shows how the extinction rate has gone up and
down over the past 540 million years. A few pulses of extinctions stand out
above the others. These mass extinctions were truly tremendous cataclysms.
The biggest of all, which occurred 250 million years ago, claimed 55% of all gen-
The island of Venice has been sinking perceptibly for centuries, but recent news is that
global warming is likely to accelerate the cataclysm that will take the city below a viable
water level in the lagoon. A possible parallel may be drawn with the unwritten British
constitution that some reformers have long been threatening to abandon, but which
continues to be the basis of a rather unusual system of government, one that is often
visited and sometimes admired by constitutional tourists from other countries.
Variable stars are those that change brightness. Their variability may be due to geometric processes such as rotation, or eclipse by a companion star, or physical processes such as vibration, ﬂares, or cataclysmic explosions. In each case, variable stars provide unique information about the properties of stars, and the processes that go on within them.
When mirror twins Seth and Hadrian Castillo travel to Europe on holidays, they don’t expect the end of the world to follow them. Seth’s murder, however, puts exactly that into motion. From opposite sides of death, the Castillo twins grapple with a reality neither of them suspected, although it has been encoded in myths and legends for
