Quantification of damage by Helicoverpa armigera on soybean is a key factor in understanding the potential of this pest to cause losses in Brazil soybean fields and determining the timing of its control. The objective of this study was to characterize and quantify the damage of H. armigera at two reproductive stages of soybean in Brazil. Four experiments were conducted at two soybean phenological...
The paper is aimed to the evaluation of the corrosion behavior of corrosion resisting alloys (CRAs) in geothermal fluids operating at the dew point.Several test series were carried out in geothermal production sites of Tuscany (Italy) under continuous flow. The vapor was extracted directly from the main flow and it was conveyed in an experimental device designed to simulate dew point conditions.Nine...
