The Panama Canal turns 100: history and possible future scenarios

This issue of the FAL Bulletin sets out a brief history of the Panama Canal, its construction and its social and political impact on Panama, within the context of international trade at the time. This issue also reviews the recovery of the canal by the Republic of Panama and subsequent major events, including the decision to expand the canal and the start-up of work on the expansion project.

Consciência e crítica da linguagem: Graciliano Ramos / Language awareness and criticism: Graciliano Ramos

Uma leitura atenta da ficção de Graciliano Ramos pode revelar uma forma aguda de refletir o mundo através de uma reflexão anterior sobre a própria linguagem da literatura e da sociedade. É uma leitura desse teor que se pretende mostrar, apoiada na conhecida teoria das funções da linguagem de Jakobson. Num jogo constante entre as funções fática e metalingüística, Graciliano Ramos demonstra visível consciência dos problemas de linguagem, cujo tratamento moderno aponta uma postura bastante crítica (via linguagem) perante o homem e a vida. An attentive of Graciliano Ramos’ fiction reveals a deep form of reflection on the world thorough a previous reflection on the very language of literature and society. Such a reading is here attempted based on Jakobson’s well known theory of language functions. In a constante play between the fatic and the metalinguistic function, Graciliano Ramos demonstrates a clear awareness of the problems of language, whose modern treatment points at a very critical poise (via language) before man and life.

Life history and DNA barcode of Oxyurella longicaudis (Birgei, 1910) (Cladocera, Anomopoda, Chydoridae)

Background: Cladocera is an important group of freshwater zooplankton, and the species plays an important role in energy transfer and in aquatic food webs. Oxyurella longicaudis is a Chydoridae species that has been recorded in North and South America. The aim of this study is to investigate the life cycle aspects of parthenogenetic females of O. longicaudis cultured in laboratory under controlled conditions: temperature (23 degrees C +/- 05 degrees C), photoperiod (12 h light/12 h dark), food supply, and reconstituted water.Results: Embryonic development duration (2.3 +/- 0.5 days), post-embryonic development (5.2 +/- 0.69 days), mean fecundity (two eggs female(-1) brood(-1)), total egg production (22.55 +/- 3.98 eggs), average longevity (58 days), and body growth of the species were recorded. We also report the first DNA barcode for O. longicaudis isolated in Brazil, which will allow for easy identification in future zooplankton community studies. The analysis shows a genetic divergence of around 7% between our Brazilian isolate and O. longicaudis isolates from Mexico.Conclusions: The time of embryonic and post-embryonic development of O. longicaudis was higher than that of the other species of the same family, which contributed to lower total egg production throughout its life cycle. The genetic divergence appears to be sufficient to classify the two isolates as different species.

Quantum confinement in hydrogen bond of DNA and RNA

The hydrogen bond is a fundamental ingredient to stabilize the DNA and RNA macromolecules. The main contribution of this work is to describe quantitatively this interaction as a consequence of the quantum confinement of the hydrogen. The results for the free and confined system are compared with experimental data. The formalism to compute the energy gap of the vibration motion used to identify the spectrum lines is the Variational Method allied to Supersymmetric Quantum Mechanics.
