Molecular phylogeny of the New World Dipsadidae (Serpentes: Colubroidea): a reappraisal

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

A revision of the New World genus Ceraeochrysa (Neuroptera: Chrysopidae).

The sixty-four known species of Ceraeochrysa Adams, 1982 are described, illustrated, and GEOGRAPHICAL DISTRIBUTIONS given. A preliminary phylogeny of the species is presented. Eleven species are newly described (C. achillea, C. angusta, C. beliaensis, C. bitacornua, C. chiricahuae, C. curvabilis, C. digitata, C. derospogon, C. diverticula, C. forcipata, and C. panamensis). Two species are returned to this genus (C. laufferi and C. placita). Three names are synonymized: Chrysopa silvestrina Navas, 1929 = Ceraeochrysa cincta (Schneider, 1851); Chrysopa gradata Navas, 1913 = Ceraeochrysa effusa (Navas, 1911); and Chrysopa aroguesina Navas, 1929 = Ceraeochrysa laufferi (Navas, 1922). Two new lectotype designations are indicated: Chrysopa cincta Schneider, 1851 and Chrysopa valida Banks, 1895. New status is given to Ceraeochrysa parvula (Banks, 1903).

Can four-fermion contact interactions at one-loop explain the new atomic parity violation results?

We investigate the possibility that four-fermion contact interactions give rise to the observed deviation from the standard model prediction for the weak charge of cesium, through one-loop contributions. We show that the presence of loops involving the third generation quarks can explain such a deviation.

The American empire in the new century: Hegemony or domination?

This chapter analyzes the current position of United States supremacy, in light of the debate on hegemony and domination that acquires greater relevance after the formulation of the 'Bush Doctrine', which is systematized in the document 'The National Security Strategy of the United States of America'. Our approach will emphasize the following aspects: establishment of a parallel between the transition from the 19th to the 20th centuries, from studies that point out the characteristics of imperialism at different times; an analysis of the current foreign policies of the United States, focusing on the debate between unilateralism and multilateralism, emphasizing the reactions caused by the intervention in Iraq; a critical argument about the approaches that highlight in the security agenda of the Bush administration an indicator of a loss of hegemony, which would impose open domination over the search for consensus.

A First approach on the new transmission system in northern Brazil

This article shows an analysis of the electrical parameters of a three-phase transmission line section using a relatively new design for steel towers characterized by 280 meters high. These main features, the height of the line conductors and distance between them, are intrinsically related to the longitudinal and transversal parameters of the line. By this means, an analysis was carried out in order to show the electrical variations between a transmission line using the new technology and a conventional 440-kV line through a wide range of frequencies and a variable soil resistivity. © 2012 The Institution of Engineering and Technology.

Power electronics courses for the new paradigms of the electrical system

This paper presents a historical perspective of the Power Electronics education that has lead to the present situation in which such technology is indispensable for the exploitation of almost all type of clean energy primary sources. Some academic initiatives in Brazil are here discussed focusing the institutions grouped in a CAPES-Pró-Engenharia program. The curricula aspects and innovations are presented, emphasizing the multidisciplinary character of this field of Power Electronics application. © 2011 IEEE.
