13. Desvio para a esquerda associado a compartimento medular de reserva dos neutrófilos não esgotado em cadelas portadoras de piometra
From fifteen female dogs with clinical diagnoses of pyometra, hematological exams were performed at three times: M0 (prior to the surgery), M24 (24h after ovarysalpingohisterectomy-OSH) and M48 (48h after OSH). Anemia was seen in 80% of the cases, characterized as mild normocytic normochromic type. The means of total leukocyte counts were 27.043, 57.940 and

14. Effectiveness of ozonated water in the reprocessing of blood dialyzers
INTRODUCTION: Ozone is a potent antibacterial agent. Because ozone oxidizes organic material, it directly attacks microorganisms resulting in safe, fast and economical sterilization at low temperatures. This study evaluated the efficacy of ozonated water in the reprocessing of dialyzers obtained from a hemodialysis service in São José do Rio Preto. METHODS

15. Assessment of sábalo (Prochilodus lineatus) fisheries in the lower Paraná River basin (Argentina) based on hydrological, biological, and fishery indicators
This study assesses the change in fish exploitation patterns of the sábalo fisheries of the lower Paraná River basin based on hydrological, biological, and fishery indicators. From historical catch records, we recorded a shift from a lightly and moderate exploited status before 2001 to a heavily exploited one, as a result of the development of sábalo expo

16. Changes in test scores distribution for students of the fourth grade in Brazil: A relative distribution analysis for the years 1997 to 2005
To assess the quality of school education, much of educational research is concerned with comparisons of test scores means or medians. In this paper, we shift this focus and explore test scores data by addressing some often neglected questions. In the case of Brazil, the mean of test scores in Math for students of the fourth grade has declined approximately

17. Simulação da dinâmica do estado excitado em semicondutores orgânicos / Simulation of the excited state dynamics in organic semiconductors
In the present work, the Monte Carlo method and the direct numerical integration of the Master Equation were employed to simulate the excitation spectral diffusion process in light emitting polymeric systems. The methodology employed a competition among the internal intra-molecular relaxation, the inter-molecular incoherent energy transfer via Förster mecha

19. USO DA ABELHA MELÃFERA (Apis mellifera L.) NA POLINIZAÃÃO E AUMENTO DE PRODUTIVIDADE DE GRÃOS EM VARIEDADE DE SOJA (Glycine max. (L.) Merril.) ADAPTADA ÃS CONDIÃÃES CLIMÃTICAS DO NORDESTE BRASILEIRO / Use of honey bees (Apis mellifera L.) in the pollination and the gain in productivity of grains in variety of soybean (Glycine max (L.) Merril.)adapted to Brazilian Northeastern climatic conditions
The research was carried out between July and December 2009 using tropical soya bean (Glycine max (L.) Merril) cultivars irrigated by center pivots in the irrigation district of Jaguaribe-Apodi, belonging to the agribusiness Faedo Sementes situated at the Apodi plateau, Limoeiro do Norte, CearÃ, Brazil. The study aimed to investigate the use of Apis mellife

23. Analysis of signal processing techniques for optical 112 Gb/s DP-QPSK receivers with experimental data
This paper evaluates several signal processing techniques for optical dual-polarization quadrature phase-shift keying (DP-QPSK) coherent receivers, using offline post-processing of experimental data. In addition to electronically separating the two polarization multiplexed signals, the investigated signal processing algorithms also compensate for chromatic d
