This study presents a new pneumatic air jet excitation nozzle, specifically designed for food processing applications. The device, which uses compressed air equipment and a precision solenoid valve, controls air discharge through a parametric air jet nozzle. Tests showed that the device could achieve shooting frequencies in the 40-45 Hz range, with operational pressures between 5 and 7 bar.

In response, a novel non-invasive ventilatory support model called CPAP-AirFlife™ was developed utilizing existing technologies. This model offers technological advantages, including an aerosol-controlled helmet suitable for high-risk environments such as ambulances.

Several systemic factors are responsible for pathologies that negatively affect its structural attributes. Although the bone is in continuous renewal by osteogenesis, metabolic diseases are the most common affectations that alter its natural equilibrium.

Article Synopsis
- Bone plays vital roles in the body, serving as a calcium phosphate reservoir and protecting organs, making its health crucial for overall metabolic balance.
- Current diagnostic methods for bone conditions are often invasive and use ionizing radiation, prompting a need for noninvasive evaluation techniques.
- This study introduces a piezo-actuated device for monitoring bone alterations through electromechanical impedance, showing that changes in bone density can be detected through electrical resistance measurements correlated to decalcification over time.
This study exposes the assessment of a piezo-actuated sensor for monitoring elastic variations (change in Young's modulus) of a host structure in which it is attached. The host structure is monitored through a coupling interface connected to the piezo-actuated device. Two coupling interfaces were considered (an aluminum cone and a human tooth) for the experimental tests.
