Use of direct-reading instruments for measuring airborne nanoparticles in the workplace

This work strived to increase knowledge of assessing airborne nanoparticles in the workplace by characterizing nanoparticle concentrations in a workplace using directreading instruments, evaluating a DC2000CE diffusion charger, and the creation of a personal diffusion battery (pDB). Direct-reading instruments were used with aerosol mapping and task monitoring to evaluate airborne nanoparticle c...

Measuring reading performance

Despite significant changes in the treatment of common eye conditions like cataract and age-related macular degeneration, reading difficulty remains the most common complaint of patients referred for low vision services. Clinical reading tests have been widely used since Jaeger introduced his test types in 1854. A brief review of the major developments in clinical reading tests is provided, fol...

Instruments for Measuring Fruit and Vegetable Environment

Environmental storage conditions, particularly air temperature, relative humidity and air velocity, have a major role in maintaining fruit and vegetable quality during cold storage. The constant low temperature, high relative humidity (RH) and moderate air flow are important to limit perishable quality. Storage temperature controls must be well calibrated to maintain a precise level of control....
