Written sources of the early Middle Ages recorded several dozen ethnonyms steppe tribes, attributed by historians to peoples Hunno–Bulgar circle. This diversity creates certain problems with identifying individual determining their localization, and analyzing chronology movements. Questions arise as how these correlated each other large nomadic empires. The main attention author was drawn a gro...

"Miswak" is an Arabic word meaning "tooth-cleaning stick," and Salvadora persica miswak has a wide geographic distribution. It was used by ancient Arabs to whiten and polish the teeth.

Perhaps the phrase "Energy Crisis," first introduced during the 1973 Arab Oil Embargo, is slightly misleading. The sun, for example, provides the world with 400 times more energy than we use each day. The unmined U.S. coal supply is large enough to meet demand in this country for several centuries. Other forms of energy that man expects to better harness in the future such as the sea, wind, bio...

The classical problem of solving an nth degree polynomial equation has substantially influenced the development of mathematics throughout the centuries and still has several important applications to the theory and practice of present-day computing. We briefly recall the history of the algorithmic approach to this problem and then review some successful solution algorithms. We end by outlining ...

Science's fascination with bone and its repair processes span for thousands of years since the ancient Greek Hippocrates, the father of Medicine, made the key discovery that bone heals without scarring. Through the centuries, several lucid investigators perceived that the extracellular matrix of bone must be a reservoir of differentiating and morphogenetic factors ultimately responsible for its...

Several cases of human combustion, the cause of which was not evident, have been described over the last few centuries. There are three intriguing elements to such cases. Firstly, although the body is destroyed, the immediate surroundings are left almost intact. Secondly, there is often no visible source of heat that might have started the fire. Thirdly, sometimes bodies are not completely dest...

The coherent contribution of all neutrons in neutrino nucleus scattering due to the neutral current offers a realistic prospect of detecting supernova neutrinos. As a matter of fact. for a typical supernova at 10 kpc, about 1000 events are expected using a spherical gaseous detector of radius 4 m and employing Xe gas at a pressure of 10 Atm. We propose a world wide network of several such simpl...

^ 200 Road systems in the service of empires have long inspired archaeologists and ancient historians alike. Using etymology, textual analysis and archaeology the author deconstructs the road system of the Khmer, empire builders of early historic Cambodia. Far from being the creation of one king, the road system evolved organically to serve expeditions, pilgrimages and embedded exchange routes ...
