background: hazardous chemicals, which give detrimental effect to the central nervous system, are widely used in the vehicle services industry. the use of vibrotactile perception threshold (vpt) as a screening tool for chemical exposure is new in developing country such as malaysia. therefore, this study determined the relationship between vpt and chemical exposure among vehicle service technic...

BACKGROUND When robots mill bone near critical structures, safety margins are used to reduce the risk of accidental damage due to inaccurate registration. These margins are typically set heuristically with uniform thickness, which does not reflect the anisotropy and spatial variance of registration error. METHODS A method is described to generate spatially varying safety margins around vital ...

Introduction Occupational exposure limits (OELs) 1 for the protection of workers have been around at least since 1939 when the National (later changed to American) Conference of Governmental Industrial Hygienists (ACGIH) published its inaugural acceptable workplace exposure limits (now known as threshold limit values, or TLVs). In 1970, the U. S. Occupational Safety and Health Act incorporated ...

Subjective sensory abnormalities, such as radiating pain, dysesthesia and llodynia, are a common feature of patients presenting to a pain clinic. Objectively quantifying those abnormalities using subjective tests ( eg tuning fork, safety pin) may be difficult. There are a number of non-invasive neurodiagnostic technologies available to supplement the history and physical exam including MRI, the...

The study performed the biomechanical testing of polymethylmethacrylate (PMMA) specimens with unreinforced progressive antibiotic loading, compared to samples reinforced Kirschner wires, by subjecting these mechanical compression forces. A difference was observed in yield which an concentration that exceeded usual amount used. In this combination vancomycin powder and liquid gentamicin, spacer ...
