We show that Ambro–Kawamata’s non-vanishing conjecture holds true for a quasi-smooth WCI X which is Fano or Calabi-Yau, i.e. we prove that, if H is an ample Cartier divisor on X , then |H | is not empty. If X is smooth, we further show that the general element of |H | is smooth. We then verify Ambro–Kawamata’s conjecture for any quasi-smooth weighted hypersurface. We also verify Fujita’s freene...

of the Sutra or traditions. When they were written down in their present form is not yet ascertained. A violent dispute has arisen among the learned whether Indian therapeutics are independent of, or influenced by, the Greeks. As among the investigators of ancient Egypt, so among those of ancient India, there are two parties,?the one who extols the knowledge of its protege to the skies, the oth...

According to one of the ancient proverbs in India,” there is no plant on earth which has no medicinal property.” More than 90% of the compounds used in modern medicine have their origin from plant sources. A large number of plants have been used by man from ancient times as medicine for curing various ailments. In recent times there is an upsurge of interest and focus on the importance of medic...

This critical and careful study aimed to gather information on the common formulation(s) found in the following ancient medical texts: the Bower Manuscript (Bower Ms.), Charak Samhita (CS), Susruta Samhita (SS), Astangahrdayam Samhita (AHS) and Ayurvedic Formulary of India (AFI). We found that only one formulation, Kalyanaka ghrita, had the same formula in all the texts. Kalyanaka ghrita was pr...

Diseases and ailments have afflicted humanity since antediluvian times. Man’s response in treating disease and, on occasion, finding its cause has been synonymous with the evolution of society, no matter how ancient. Therefore, medicine as we know it today is as old as Man, and must have developed with the first awakening of human consciousness, evolving with successive civilisations. It is the...

The evolutionary history and age of Plasmodium vivax has been inferred as both recent and ancient by several studies, mainly using mitochondrial genome diversity. Here we address the age of P. vivax on the Indian subcontinent using selectively neutral housekeeping genes and tandem repeat loci. Analysis of ten housekeeping genes revealed a substantial number of SNPs (n = 75) from 100 P. vivax is...

I In various writings over the years Amartya Sen has shown his acute interest in comparative performance of China and India, the two largest countries of the world, both with poor, agrarian economies and with rich, ancient civilizations. While high economic growth in both countries in the last decades has attracted a lot of attention, particularly in the international financial press, Sen's int...
