Consaquently, the vibrations inftuence can be dear1y systematized in two distinct categories: whole body vibrations - with significant affects ln the entire human body; vibrations on different sections of the body - that transmit significant accelerations and displacements only in soma sections, such as the hand·arm system. Whlle the first category- registered mainly ln the professional driving sector - has baen constantly studied and different solutions for vibration allenuation have baen proposed, the handarm vibration domain is stlll open for discussions. This paper presents a complex study - both from the medical and engineering point of view - regarding the modelhng and tesbng methods used for hand-arm system vibrations in the view of professional diseases prevention. Il aims to evalualing preventive strategies to reduce wor1<er exposures to hand-arm trensmitted vibration and to decrease the occurrence of Hand-Arm Vibretion Syndrome (HA VS) in waterenIsolated zygotic embryoGerminationProliferationMicropropagationCulturemediumPistaciavera LOther
