The presence of microplastics (MPs) in gut contents of coastal freshwater fish of the Rio de la Plata estuary was studied. Samples were taken in six sites where 87 fish belonging to 11 species and four feeding habits were captured. Presence of MPs was verified in the 100% of fish. The fibres represented the 96% of MPs found. The number of MPs in gut contents was significantly higher close to sewage...
The influence of the temperature on Metal Gate/Al2O3/n-InGaAs stacks has been studied by means of capacitance-voltage (C-V) hysteresis and flat band voltage as function of both negative and positive stress fields. It was found that the de-trapping effect decreases at low-temperature, indicating that the de-trapping of trapped electrons from oxide traps may be performed via Al2O3/InGaAs interface defects...
In this paper, we propose a method for designing the optimal sensing of measurements which can be characterized by a sparse linear model. The aim of the sensing operation is not only to reduce the amount of data to be processed but also to reject undesired signals (interferences). As a result, we reduce the computation time and the error for estimating the unknown parameters of the model, with respect...
