Difusão do trabalho agrícola formal no Brasil e sua dinâmica multiescalar

This paper aims to analyze the geographical dynamics of work from the spread of formal employment in the agricultural sector in Northeast Brazil. In recent years the region has had highlighted a growing movement to produce fruit for export, resulting in the promotion of important sociospatial transformations arising from the formation of a capitalist labor market. Data about the increase in the number of formal jobs show the impact of fruit growing agribusiness in the establishment of a new social and territorial division of labor. However, our study draws attention to the existence of a framework dominated for the vulnerability of the labor market by the persistence of seasonality and precarious working conditions.

Cambio tecnológico en la industria venezolana de maquinaria agrícola: estudios de caso

Reune tres estudios de caso referidos a empresas de maquinaria agricola en Venezuela. En cada uno de ellos, se analiza la evolucion tecnologica de la firma, los factores que la determinan y la incidencia que tiene su conducta en la posicion relativa en el mercado. Presenta algunas reflexiones, derivadas de los estudios de caso, sobre la interaccion entre el desarrollo de las formas del mercado y la naturaleza y distinto enfasis que dedican las empresas durante su evolucion al esfuerzo tecnologico en cada una de las areas tecnicas de ingenieria de diseno, proceso de produccion y de organizacion industrial.

Influência de pontas de pulverização e adjuvantes no potencial de redução de deriva em túnel de vento

The drift is intimately linked to inappropriate use of pesticides and an important factor for reducing it, is the correct selection of spray nozzles and adjuvants. The objective of this work was to evaluate the drift potential in wind tunnel with different spray nozzles and different concentrations of adjuvants. The experiment was composed by six spray solutions (vegetable oil (in three concentrations), mineral oil, surfactant and reducing drift), which were applied with two nozzles, one pre-orifice flat fan (DG 8003 VS) and other with air induction (AI 8003 VS), totaling 12 treatments, with three repetitions. The equipment used was a wind tunnel, where the drift collections were made at different points. The treatments averages were compared using Confidence Interval at 5% probability. The analysis of the percentage of drift showed that the treatments had different behaviors. The nonylphenol ethoxylate adjuvant presented the highest drift when applied with the nozzle of pre-orifice and the lowest drift when applied with the air induction. The behavior of these nozzles when the oil-based adjuvant was used showed apposite results to those obtained for the surfactant. For the DG nozzles the lowest percentage of drift, at all analyzed distances, was observed to the treatment with vegetable oil (1.0%) and with the AI nozzles the lower drift was found for the treatment with nonylphenol ethoxylate (0.0625%), for the four distances in the collection. The result showed that both the spray nozzles and adjuvants alter directly the drift potential. There was no proportionately between the concentration of the oil-based adjuvant and the drift percentage.
