There are a number of errors in Table 3. The table legend should read: Breakdown of economic costs of rabies by cluster in millions of USD. The headings for columns six, seven, and eight are incorrect. They should be in the following order: Dog vaccination, Dog population management, Livestock losses. Please see the correct Table 3 below.

Se investigó la actividad antimicrobiana in vitro de los extractos metanólicos, etanólicos e hidroalcohólicos de cuatro plantas del nor-oriente peruano: Cassia reticulata (planta entera), Ilex guayusa Loes (hojas), Piper lineatum (hojas), y Terminalia catappa (hojas). Las especies fueron recolectadas en el departamento de Cajamarca, excepto Terminalia catappa (Amazonas). La actividad antimicrobiana se evaluó mediante el método de difusión en agar. Los microorganismos utilizados fueron las bacterias Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginosa, Bacillus subtilis y Escherichia coli; y los hongos Candida albicans, Aspergillus niger y Microsporum canis. De doce extractos investigados, ocho (67%) presentaron actividad antimicrobiana significativa frente a Staphylococcus aureus y Staphylococcus epidermidis y uno (8%) frente a Escherichia coli. De doce extractos investigados, diez (83%) presentaron actividad significativa frente a Candida albicans, y seis (50%) contra Microsporum canis. Los extractos con la mejor actividad actimicrobiana fueron los tres extractos del Piper lineatum; el extracto hidroalcohólico de Cassia reticulata y el hidroalcohólico de Terminalia catappa.

The gas turbine combustion chamber is one of the most critical components to be designed, because it must ensure a stable operation in a wide range of air/fuel ratio and load. Among several calculations involved in the design of a combustion chamber, the reference area is the most important physical parameter, especially by the great impact on other dimensions. In general, this parameter must be calculated from an analysis of the limitations imposed both chemical reactions and aerodynamics, i.e., based on combustion process requirements and maximum pressure drop allowable in the combustion chamber, respectively. So, the aim of this paper is investigate the influence of the reference area in the velocity profile, in the temperature distribution, in the mixing process and in the flame behavior, according to the reference area used in the combustion chamber. These numerical analyses were carried out using ANSYS CFX®, comparing them with the base value calculated by Lefebvre [5], for a thermodynamic cycle of 600 kW gas turbine engine, conduced in GateCycle® program. Finally, it can be concluded that some changes in the reference area calculated by Lefebvre [4] produces better results, especially by improving the burning process and the behavior of the flame.
