Is there a Population II analogy to the F star lithium dip?

Observers have found a small number of lithium-depleted halo stars in the temperature range of the Spite plateau. The current status of the mass-loss hypothesis for producing the observed lithium dip in Population (Pop) I stars is briefly discussed and extended to Pop II stars as a possible explanation for these halo objects. Based on detections of F-type main-sequence variables, mass loss is assumed to occur in a narrow temperature region corresponding to this “instability strip.” As Pop II main-sequence stars evolve to the blue, they enter this narrow temperature region, then move back through the lower temperature area of the Spite plateau. If 0.05 M⊙ (solar mass) or more have been lost, they will show lithium depletion. This hypothesis affects the lithium-to- beryllium abundance, the ratio of high- to low-lithium stars, and the luminosity function. Constraints on the mass-loss hypothesis due to these effects are discussed. Finally, mass loss in this temperature range would operate in stars near the turnoff of metal-poor globular clusters, resulting in apparent ages 2 to 3 Gyr (gigayears) older than they actually are.

Mathematical approaches to comparative linguistics‡

The inference of the evolutionary history of a set of languages is a complex problem. Although some languages are known to be related through descent from common ancestral languages, for other languages determining whether such a relationship holds is itself a difficult problem. In this paper we report on new methods, developed by linguists Johanna Nichols (University of California, Berkeley), Donald Ringe and Ann Taylor (University of Pennsylvania, Philadelphia), and me, for answering some of the most difficult questions in this domain. These methods and the results of the analyses based on these methods were presented in November 1995 at the Symposium on the Frontiers of Science held by the National Academy of Sciences.

Bike and cycle polo's terminology translation issues from a cognitive linguistics perspective

The purpose of this dissertation is to give a contribution to the translation of the terminology of Cycle and Bike Polo into European Portuguese and hence call the attention of a wide Portuguese public to this fairly new sport, whose roots go back to Elephant and Horse Polo in India and in other parts of the world. Sequencing a characterization of technical translation, translation issues of Bike and Cycle Polo´s terminological units have been dealt with in the light of the Cognitive Linguistics framework and hence intimately associated both with physical experiences and historical facts. In fact, sports terminology coinage in this field is highly motivated by metaphorical and metonymical conceptualization mapped from physical reality dimensions, as well as from already existing sports terminology from other sports modalities. In order to render this research unique, a glossary of technical terms from Bike and Cycle Polo has been gathered, since most of them had not yet undergone translation from English into European Portuguese. For validation of my translations I have resorted to Portuguese bike polo players, with special reference to Catarina Almeida, who introduced me to Bike Polo’s terminology.
