background: drivers of heavy motor vehicles are occupationally exposed to intense whole body vibration (wbv) for several hours per day over their working lifetime. therefore, they are at risk of wbv-induced occupational disorders. this study aimed to investigate health effects of long-term exposure to whole body vibration among a group of heavy vehicle drivers in fars province, southwestern ira...

Blast-induced traumatic brain injury (bTBI) is the "signature wound" of the current wars in Iraq and Afghanistan. However, with no objective information of relative blast exposure, warfighters with bTBI may not receive appropriate medical care and are at risk of being returned to the battlefield. Accordingly, we have created a colorimetric blast injury dosimeter (BID) that exploits material fai...

Traumatic brain injury (TBI) has been diagnosed in nearly 300,000 members of the US armed forces since 2000 [1]. Common symptoms of these injuries include concussion, loss of spatial navigation, behavior/mood changes and memory loss [2‐3]. Blast‐related TBI poses a significant problem for military personnel both in combat and in training. Primary blast loading, the blast loading caused by the i...

Spraying systems to protect crops against pests are still necessary maintain food production at the rates demanded by current population. However, today, it is crucial use precision agriculture reduce negative effects of pesticides and other agrochemicals such as fungicides. In particular, pressure fluctuations related transient states when using pulse-width-modulated nozzles (PMW) have been re...

Abstract In the process of Open-pit mining in China, throwing blasting is an important method, which very likely to cause serious damage slope discharge field under action vibration load blasting. With background Heidaigou open-pit mine Ordos, velocity data were collected from near blast, and signal blast was analyzed by means Fourier transform obtain characteristics wave attenuation law predic...

BACKGROUND Cast immobilization induces mechanical hypersensitivity, which disturbs rehabilitation. Although vibration therapy can reduce various types of pain, whether vibration reduces immobilization-induced hypersensitivity remains unclear. OBJECTIVE The purpose of this study was to investigate the preventive and therapeutic effects of vibration therapy on immobilization-induced hypersensit...
