Vibroacoustical Performance Analysis of a Rigid Device Casing with Piezoelectric Shunt Damping.

Noise and vibration are common issues that may have a negative impact on human's' health. To minimize their consequences, several vibroacoustical methods may be employed. One well-known method is Piezoelectric Shunt Damping (PSD).

Chladni Figures in Modal Analysis of a Double-Panel Structure.

Analysis of the structural vibration, under the sound excitation is an important part of the quality assurance during the design process of devices. One of the most commonly used method is Laser Doppler Vibrometry (LDV). However, under the rapid fluctuations of temperature, structural resonances are shifted into the other frequencies.

Spectral Analysis of Macro-Fiber Composites Measured Vibration of Double-Panel Structure Coupled with Solenoids.

Noise may have a negative impact on humans health and well being. Noise is a direct result of the vibration of structures. Many industrial workers and people using household appliances may be exposed to these harmful factors.

A case of extensive inflammatory changes (osteomyelitis) in an infant's skeleton from the medieval burial ground (11th-12th c) in Wawrzeńczyce (near Krakow).

The aim of this study was to diagnose and describe extensive inflammatory changes in a child's skeleton from Wawrzeńczyce, (the medieval period). The aim of the analysis was to determine the nature of the inflammatory changes and their etiology by means of macroscopic techniques as well as X-ray analysis. The tests revealed that the individual suffered from a hematogenous multifocal osteitis.
