This study explores the concept of new energy infrastructures (in particular gas pipelines) in Eurasia and discusses its implications on future energy systems, gas trade, and the environment. Overall resource availability is not expected to be a real constraint in meeting growing energy demand within the next 100 years, but the geographical concentration of resources is. The expected increase i...

For the design of a special gas-flow proportional counter intended for a new on-line measurement method of airborne radon (Rn) concentration, the amplification properties of four gas compositions were investigated in air-mixed Argon-propane (1%)-based proportional counters. These four gas compositions are: Ar-C3H8 (1%); Ar-C3H8 (1%) + 2% air; Ar-C3H8 (1%) + 6% air and Ar-C3H8 (1%) + 10% air. Th...

In this work 1 the curvature of Weinhold (thermodynamical) metric is studied in the case of systems with two thermodynamical degrees of freedom. Conditions for the Gauss curvature R to be zero, positive or negative are worked out. Signature change of the Weinhold metric and the corresponding singular behavior of the curvature at the phase boundaries are studied. Cases of systems with the consta...

Toward a Global Science and Technology Policy Agenda for Sustainable Development T current economic crisis has tended to sap the policy momentum that had developed during 2006 and 2007 behind public R&D programmes and institutional initiatives to expand the portfolio of affordable technological means of controlling global warming. This is unfortunate, since the international negotiations about ...
