Qua Re qui possum non esse popularis: The representation of Populares in the Late Roman Republic.

The terms popularis and optimate have been employed in both ancient and modern literature to interpret late Roman Republican politics. The purpose of this work is to express the diversity and change of the popularis label from 133 to 88 B.C. as a consequence of developing political practices. A chronological assessment of five key popularis tribunes in this period; Ti. Sempronius Gracchus, G. Sempronius Gracchus, L. Appuleius Saturninus, M. Livius Drusus and P. Sulpicius Rufus determines the variation in political methodologies exploited by these men in response to an optimate opposition. An assessment of Cicero’s works then considers how the discrepancies exhibited by these politicians could be manipulated for oratorical advantage. This subsequently reveals the perception of pre-Sullan populares in the time of Cicero, a generation later. This work ultimately aims to demonstrate the individualistic nature of late Republican politicians, the evolution of political practice in the period and the diverse employment of political labels in contemporary sources

Healing an Ailing Alliance: Ethics and Science Face the Ambiguities of Water

Water-related problems are both scientific and ethical issues. The sciences and ethics are interdependent disciplines, and both are needed in an interactive alliance for adequate policy decisions on water and other ecological concerns. Water-related problems are generally linked to excess in what people take from and return to the waters. In this essay, the author outlines four moral norms that are foundational for remedial action on the waters of New England

Topological Aspects of the Non-adiabatic Berry Phase

The topology of the non-adiabatic parameter space bundle is discussed for evolution of exact cyclic state vectors in Berry's original example of split angular momentum eigenstates. It turns out that the change in topology occurs at a critical frequency. The first Chern number that classifies these bundles is proportional to angular momentum. The non-adiabatic principal bundle over the parameter space is not well-defined at the critical frequency.Comment: 14 pages, Dep. of Physics, Uni. of Texas at Austin, Austin, Texas 78712, to appear in J.

Application of solar energy to air conditioning systems

The results of a survey of solar energy system applications of air conditioning are summarized. Techniques discussed are both solar powered (absorption cycle and the heat engine/Rankine cycle) and solar related (heat pump). Brief descriptions of the physical implications of various air conditioning techniques, discussions of status, proposed technological improvements, methods of utilization and simulation models are presented, along with an extensive bibliography of related literature
