2. Usefulness of a multiplex PCR for the rapid identification of Candida glabrata species complex in Mexican clinical isolates
ABSTRACT Candida glabrata complex includes three species identified through molecular biology methods: C. glabrata sensu stricto , C. nivariensis and C. bracarensis . In Mexico, the phenotypic methods are still used in the diagnosis; therefore, the presence of C. nivariensis and C. bracarensis among clinical isolates is still unknown. The aim of this study w

3. The breeding biology, nest success, habitat and behavior of the endangered Saffron-cowled Blackbird, Xanthopsar flavus (Aves: Icteridae), at an Important Bird Area (IBA) in Rio Grande do Sul, Brazil
ABSTRACT The Saffron-cowled Blackbird, Xanthopsar flavus (Gmelin, 1788), is a globally vulnerable icterid endemic to grasslands and open areas, and a priority species for research and conservation programs. This contribution provides information on the population size, habitat, behavior, breeding biology and nest success of X. flavus in two conservation unit

4. Critical Forces at Fractional Matching Fields in Superconducting Thin Films with Triangular Pinning Lattice
We numerically study the commensurability effects in the critical forces in a type II superconducting thin film with vortices under the influence of a triangular pinning lattice at sub matching fields and zero temperature. The analysis is made applying a transport force in two mutually perpendicular directions and magnetic field perpendicular to the film sur

5. Maximum Power Transfer versus Efficiency in Mid-Range Wireless Power Transfer Systems
AbstractThe condition for maximum power transfer of 2-coils wireless power transfer (WPT) system is derived from circuit analysis and discussed together with the respective WPT system efficiency (η). In the sequence, it is shown that a 4-coils WPT system (which can be divided in source, two communication and load circuits) without power losses at the two co

6. Codificação de vídeo baseada em fractais e representações esparsas / Video coding based on fractals and sparse representations
A video is a sequence of still images representing scenes in motion. A video is a sequence of extremely similar images separated by abrupt changes in their content. If these images were transmitted and stored without any kind of preprocessing, this would require a massive amount of storage space and communication channels with very high bandwidths. Lossy com

7. Análise em larga escala da expressão diferencial de Corynebacterium pseudotuberculosis em resposta a estresses abióticos
Uma nova tecnologia de sequenciamento de cDNA tem permitido uma análise detalhada e aprofundada dos transcritos em procariotos. Corynebacterium pseudotuberculosis, uma bactéria causadora de doenças, como a linfadenite caseosa, que trazem grandes prejuízos econômicos para o agronegócio mundial, foi o alvo de nossos estudos. Neste contexto, caracterizamo

10. The rates in complete moment convergence for negatively associated sequences
Let X1, X2,... be a strictly stationary and negatively associated sequence of random variables with mean zero and positive, finite variance, set Sn = X1+ ... + Xn, Mn = max1 < k < n |Sk|. Under appropriate moment conditions, we obtain precise rates in law of the logarithm for the moment convergence of Sn and Mn.

11. Performance of coupling an activated sludge reactor with heterogeneous photocatalysis (TiO2/UV) for removing the color of an industrial wastewater / Desempenho do acoplamento de um reator de lodo ativado à fotocatálise heterogênea (TiO2/UV) no descoramento de um efluente industrial
Generally, wastewaters can be easily treated by biological reactors with a good efficiency regarding organic matter removal. However, the process can be impaired in the presence of compounds that are toxic or have low biodegradability. Advanced Oxidation Processes (AOPs) may be a choice to oxidize these compounds and minimize their toxicity and/or increase b
