Forestry workers are exposed occupationally to a number of harmful or harmful factors in their working environment (whole body and hand-arm vibration, acoustic and infrasonic noise, biohazards, musculoskeletal loads and other) that may cause a variety of workrelated or occupational diseases (e.g. vibration syndrome, noiseinduced hearing loss, hand-arm, infectious and parasitic diseases, allergi...

A Optical Fiber Vibration pre-Warning System (OFVWS) has an ability to detect and identify vibration signals by using a optical fiber cable lain along with pipes, hence it has been widely applied in some safety fields, such as the pipeline transportation, national defense, military base and so on. In the application of the OFVWS, one of the key issues is to identify harmful mechanical vibration...

INTRODUCTION Whole-body vibration can resulted in low-back pain, disc degeneration and other harmful effects to the body [1]. Researchers are investigating optimal solutions for reducing vibration and seat pressure exposure of electric power wheelchair users [2, 3, 4]. The purpose of this study was to investigate the effectiveness of the newly designed waterfilled cushion (NDWF), based on vibra...

Background and purpose: Vibration caused by ventilation systems in buildings is one of the harmful physical factors that can cause harm to residents. Therefore, measuring and controlling vibration is important. Materials and Methods:  In the first step of the study, the vibration accelerometer was placed on the base of a fan where the vibrations were sent toward the duct wall. A vibration asse...

Pipe joints have been widely utilized in industrial plants, where dynamic load of vibration is considerably harmful for sealing performance. However, there is a lock of design codes and experimental procedures developed for vibration testing of pipe joints. This paper proposes an experimental setup for testing of pipe joints, which use metal gaskets, in vibratory conditions. Also, a flexible pi...

INTRODUCTION Approximately 4 to 7 percent of workers are exposed to potentially harmful levels of WBV in Canada, the United States, and some European countries [1]. Exposure to vibration is known to cause certain physiological responses. However, there is still a lack of understanding on how these responses tax the neuromuscular system. The objective was To investigate whether exposure to vibra...
