Measurements of cardiac Pre-Ejection period using a combo PPG-ECG system

The extraction of biomedical parameters, for early disease detection, is assuming today an ever increasing and fundamental importance. In particular, in the cardiologic field, the preejection period (PEP) is the duration of the iso-volumetric left ventricle contraction until the aortic valve opening. This parameter is a non-constant additive delay, which rapidly changes in response to stress, emotion and physical effort. To estimate this period, several wearable electronics devices have been developed in literature, and among them the Impedance Cardiogram equipment is the most used. However, these systems are often expensive and bulky. In this paper, we propose a cost-effective and easy to …

Assessment of synthetic chemicals for disruption of Rhynchophorus ferrugineus attraction

The red palm weevil (RPW), Rhynchophorus ferrugineus, Olivier (Coleoptera: Curculionidae), is currently one of the most severe pests of Canary palms in urban areas of Mediterranean countries and Date palms in cultivated areas of the Middle East. RPW aggregation pheromone can be implemented for both monitoring and mass trapping, however risks of RPW "spillover" onto palms is of great concern. Aiming to discover repellent semiochemicals for safer RPW population management, we conducted electroantennographic (EAG) screenings of 17 commercially available synthetic compounds. These compounds represent three groups of plant volatiles (isoprenoids, phenyl propanoid derivatives and fatty acid deriv…
