This paper describes the state of the art of a simplified model for integration of services in mega events. The project context, which was financed by the National Research Council – CNPq, is divided into six major areas or functional groups: Urban Mobility, Tourism, Airports, Security, Energy and Telecommunications. The proposal is described in layers, as an infrastructure model of integration and services evaluation, describing its main layers and interaction processes. The proposal described in this paper is restricted to the telecommunication subproject; however, in the modeling of the scenario for the study case, it was necessary to consider requirements and variables that are common to all subprojects. In the specification process of these requirements, we noticed important processes that interact with some sectors in the city of São Paulo; however, in the mean time, we noticed some failures regarding the integration and collaboration performed by administrative elements of stadiums as a main focus in the mega event and part of our case study. Currently, the proposal is in its first version as open software for the evaluation of the services quality and the mega event infrastructure through the use of performance indicators.

The objective was evaluating the effect of plant spacing on seed yield and quality in Bracchiaria brizantha cv. Marandú. The experiment was carried out in rain fed conditions in 2007 at the Universidad de Papaloapan, Loma Bonita, Oaxaca, Mexico. Six plant distances (broadcast, 25*25 cm, 50*50 cm, 75*75 cm, 100*100 cm and 125*125 cm between rows and plants, respectively) were assessed. To that end, a completely randomized block design with four replicates was set. The following variables were analyzed: pure seed yield (PSY), pure germinable seed yield (GPSY), number of panicles per m-2, panicle length, seed harvested per panicle, 1,000 seed weight, spikelet abscission rate, seed purity and germination. PSY and GPSY showed differences among treatments (P<0.01) and the highest values (47,8 and 11.0 kg ha-¹, respectively) were obtained at the 25*25 cm spacing. Panicle length, number of seed harvested in each panicle, 1,000 seed weight, seed purity and spikelet abscission rate also showed differences among treatments (P<0.05). Seed purity was the variable more closely linked to PSY and PGSY, showing r values of 0.81 and 0.55, respectively. Plant spacing did not influence germination rate (P>0.05). As a conclusion, it can be stated that the largest seed yield was obtained at the 25*25 cm spacing between rows and plants, respectively. Seed germination did not improve in any of the treatments being assessed.

El objetivo fue evaluar el efecto de la distancia entre plantas en el rendimiento y calidad de semilla de Brachiaria brizantha cv. Marandu. El experimento se realizó en temporal durante 2007, en la Universidad del Papaloapan, Loma Bonita, Oaxaca. Se evaluaron seis distancias entre plantas (voleo, 25 x 25, 50 x 50, 75 x 75, 100 x 100 y 125 x 125 cm entre líneas y plantas, respectivamente), con un diseño de bloques completos al azar, con cuatro repeticiones. Se midió el rendimiento de semilla pura (RSP), rendimiento de semilla pura germinable (RSPG), número de panículas m-2, longitud de panícula, número de semillas cosechadas por panícula, peso de 1,000 semillas, porcentaje de dehiscencia, semilla pura y germinación. El RSP y RSPG varió entre tratamientos (P<0.01), donde los mayores valores (47.8 y 11.0 kg ha-1, respectivamente) ocurrieron con la distancia 25 x 25 cm. La longitud de panícula, número de semillas cosechadas por panícula, peso de 1,000 semillas, porcentaje de semilla pura y dehiscencia de la semilla presentaron diferencias entre tratamientos (P<0.05). El porcentaje de semilla pura fue el componente con mayor grado de asociación con el RSP y RSPG, con valores de 0.81 y 0.55, respectivamente. El porcentaje de germinación no fue afectado por la distancia entre plantas (P>0.05). Se concluye que el mayor rendimiento de semilla de B. brizantha cv. Marandu, se logró con la distancia 25 x 25 cm entre líneas y plantas, respectivamente. La germinación de la semilla no fue mejorada por ninguno de los tratamientos evaluados.
