Himalayan Journal of Sociology & Anthropology-Vol. III Pollution of Seti River in Pokhara An Anthropological Perspective Amrit Kumar Bhandari Abstract Seti River is one of important components of the ecology of Pokhara so it holds a great significance for maintaining ecological balance and fulfilling different types of needs of people here. But only a few people are aware of its real value whil...

Framing interstellar messages as art projects is a recent development. The Search for Extraterrestrial Intellligence, or SETI, has been conducted by scientists and engineers, with minimal input from the artistic community. With advances in search technology, the chances of detecting extraterrestrial intelligence are improving rapidly (see Werthimer and Morris’s abstract below). In recognition o...

We critically investigate some evolutionary aspects of the famous Drake equation, which is usually presented as the central guide for research on extraterrestrial intelligence. It is shown that the Drake equation tacitly relies on unverified assumptions on both the physicochemical history of our galaxy and the properties of advanced intelligent communities. In this manner, the conventional appr...

We have developed a very sensitive, highly selective, non-destructive technique for screening inhomogeneous materials for the presence of superconductivity. This technique, based on phase sensitive detection of microwave absorption is capable of detecting 10(-12) cc of a superconductor embedded in a non-superconducting, non-magnetic matrix. For the first time, we apply this technique to the sea...

Chiral separations of fluorescein isothiocyanate-labeled amino acids have been performed on a microfabricated capillary electrophoresis chip to explore the feasibility of using such devices to analyze for extinct or extant life signs in extraterrestrial environments. The test system consists of a folded electrophoresis channel (19.0 cm long x 150 microns wide x 20 microns deep) that was photoli...

In SETI (Search for Extraterrestrial Intelligence) conventional wisdom has it that the probability of direct contact by interstellar travel is vanishingly small due to the enormous distances involved, coupled with the velocity-oflight limitation. Alcubierre's recent "warp drive" analysis [Class. Quantum Grav. 11, L 73 (1994)] within the context of general relativistic dynamics, however, indicat...

Anomalously high platinum group element concentrations have previously been reported for Upper Triassic deep-sea sediments, which are interpreted to be derived from an extraterrestrial impact event. Here we report the osmium (Os) isotope fingerprint of an extraterrestrial impact from Upper Triassic chert successions in Japan. Os isotope data exhibit a marked negative excursion from an initial O...

fXY = fYX. Problems of this type can be multiplied indefinitely, and a general theory of partial differentiation in the large to cover all such problems is desirable. We have started to construct such a theory. Among the various theorems which we have proved are three which we announce in this note as follows. THEOREM 1. Let f(x, y) be of class C' on an open point set H. Let the four second par...
