The military changes that have transformed global politics in recent years - especially since the end of the Cold War - have brought about a new revolution in military affairs (RMA) by the United States. Our carefully selected sample covers a significant range in orbital periods and understanding the properties of such Keplerian discs around binaries, will provide also insight in the role of binarity in the shapes and shaping of (proto) Planetary Nebulae. With the new sample of IRS spectra, and our detailed modeling with state-of-the art radiative transfer codes based on modern laboratory data, we aim at a better understanding of the rich chemistry and strong processing of the different gas and dust components. The detailed structure, let alone the formation, stability and evolution of the circumbinary discs around evolved stars are not well understood. They are therefore a unique laboratory to study the gas physics and dust mineralogy of Keplerian discs on quite different evolutionary timescales and radiation fields than during the star formation process. environment around the evolved stars resemble very much the protoplanetary discs around young stellar objects. The ISO-SWS spectra of only the few brightest examples, have shown that concerning mass, kinematics, mineralogy and dust processing, the circumstellar. Through detailed observing campaigns, we have recently established that these binaries are surrounded by a Keplerian dusty disc. We propose to obtain IRS spectra in the SH and LH mode of a sample of carefully selected binary post-AGB stars. With missions that focused more on training and provision of problem-solving methods to serve military needs. They had a strong imprint on the war-time activities Furthermore,ĭuring the war, academic institutions were developed both in the North (under the Soviet academic model, e.g., Hanoi Polytechnic)Īnd the South Vietnam (more like the Western style, e.g., Can Tho University). In the fields of medicine, pharmacology, or biomedicine, such as the Pasteur Institute, were established by the French. In addition, some research institutes operating pharmaceutical fields) was established in Hanoi. The first modern Vietnamese university (specializing (research institutes and universities) date back to the French regime. This has had a strong influence on the evolution of the academic system. Vietnam has been experiencing dramatic changes over the past few decades in almost all its political, social, and economic
