Bone- Carvings with Floral decorations from Roman Egypt

Incest Laws and Absent Taboos in Roman Egypt

Biogas generation from floral waste using different techniques

There is a great need to implement low-cost and user-friendly methods for further propagation of biogas technology in India. Environment unfriendly disposal of floral waste causes serious environmental pollution. Literature shows a limited research work regarding the anaerobic digestion of floral waste for biogas generation.  The present experimental work aims to propagate floral waste as a sus...

The Evolution of Land Rights: Public Farmers and Privatization in Roman Egypt

In his classic book, Structure and Change in Economic History, Douglass North sums up the nature of the ancient Egyptian state. As religious ruler, the pharaoh was the ultimate owner of land, which was controlled mainly by temples and state officials. But when the Romans conquered Egypt in 30 BC, agrarian property rights were at a turning point. Private landowners became politically dominant an...

Flux Hamiltonians, Lie Algebras and Root Lattices With Minuscule Decorations

We study a family of Hamiltonians of fermions hopping on a set of lattices in the presence of a background gauge field. The lattices are constructed by decorating the root lattices of various Lie algebras with their minuscule representations. The Hamiltonians are, in momentum space, themselves elements of the Lie algebras in these same representations. We describe various interesting aspects of...
