By explicitly taking into account effects of Alfvén waves, I derive from a simple energetics argument a fundamental relation which predicts solar wind (SW) speeds in the vicinity of the earth from physical properties on the sun. Kojima et al. recently found from their observations that a ratio of surface magnetic field strength to an expansion factor of open magnetic flux tubes is a good indica...
Earthquakes are natural phenomena that cause terrible disasters for human society. Many of the caused by earthquakes around world serve as warnings to us about fragility life and immaturity science - especially construction science. For earth dams, which made up mostly compacted earth, most common type in world, an earthquake can have enormous consequences if it causes a dam failure. Thus, prop...
As the durations and distances involved in human exploration missions increase, the logistics associated with the repair and maintenance becomes more challenging. Whereas the operation of the International Space Station (ISS) depends upon regular resupply from the Earth, this paradigm may not be feasible for future missions. Longer mission durations result in higher probabilities of component f...
We study the effects of a non-singular gravitational potential on satellite orbits by deriving the corresponding time rates of change of its orbital elements. This is achieved by expanding the non-singular potential into power series up to second order. This series contains three terms, the first been the Newtonian potential and the other two, here R1 (first order term) and R2 (second order ter...
At the 2002 Johannesburg World Summit on Sustainable Development, 190 countries endorsed a commitment to achieve, by 2010, a significant reduction of the current rate of biodiversity loss at the global, regional and national levels. A wide range of approaches is available to the monitoring of progress towards this objective. The strengths and weaknesses of many of these approaches are considere...
Earth-Shelter construction is one of the aspects in architecture where the thermal mass of the earth behind the outer walls are applied in order to reduce heat loss and keep the internal temperature at human comfort range. In case of earth-shelter buildings, housing is especially important. As for its applicability the earth-shelter provides good housing. Typological studies of earth-shelter co...
In this paper, we recall the mutation of the Minkowski spacetime for empty space into the covering isospacetime caused by physical media; we recall its experimental verifications via the isoredshift of laser light in a metal pipe containing air at pressure, as well as additional experimental verifications in other fields; and we present, apparently for the first time, experimental confirmations...
This paper offers an ethically, philosophically and sociologically founded study of privacy in a digital environment of transformed humanness. The focus is on emergent trends in search technology, in particular Google’s powerful search engine, which contributes to the distribution and “stretching” of human life by making unsorted information available through keyword and -phrase searches. The p...
The monitoring of Earth’s and planetary surface elevations at larger finer scales is rapidly progressing through the increasing availability resolution digital elevation models (DEMs). Surface observations are being used across an expanding range fields to study topographical attributes their changes over time, notably in glaciology, hydrology, volcanology, seismology, forestry geomorpho...
