Direct Study of the Particle Differential Mobility Analyzer (DMA) Systems: a review article
Background & Aim: One of the unknown equipment inside our country, especially for researchers, is the DMA system, which used to particle size distribution, especially for nanoparticles. The purpose of this paper was to review the studies carried out in this field, assessment of the evolution and importance of the application of this system and introduce the true position of this system among re...
متن کاملDetermination of Aerosol Particle Size Distribution using Electrical Differential Mobility Analyzer (DMA)
Introduction: Determining the size distribution of the particles for assessing their effects on human health and their control mechanisms is very effective. One of the most important equipment used in determining particle size distribution is the DMA. In this study, in addition to the design and construction of a DMA, the size distribution measurement of aerosol particles was carried out. Mate...
متن کاملAnalysis of α - particle induced incomplete chromosome aberrations , using pan - centromeric and pan - telomeric DNA probes
The aim of the present study has been the evaluation of the incompleteness of αparticle induced chromosome aberrations by the simultaneous detection of all centromeres and telomeres present in human lymphocytes. For this purpose attached lymphocytes were irradiated at doses of 0.2, 0.5, 0.7 and 1 Gy in a Am source. FISH techniques were applied using pan-centromeric and pan-telomeric probes. All...
متن کاملintraocular pressure measurements after penetrating keratoplasty using the ocular response analyzer versus goldmann applanation tonometer
purpose: to compare intraocular pressure (iop) readings measured by the ocular response analyzer (ora) with those measured by the goldmann applanation tonometer (gat) in keratoconic eyes following penetrating keratoplasty (pkp) and to evaluate the influence of anatomical and biomechanical properties of the grafts on iop measurements. methods: this cross-sectional study was conducted on 45 kerat...
متن کاملCompact solid-state neutral particle analyzer in current mode.
Solid state neutral particle analyzer (ssNPA) arrays are operated in current mode on the DIII-D tokamak and the National Spherical Torus Experiment (NSTX). Compared with conventional pulse-counting NPAs, current-mode operation sacrifices energy resolution to obtain economical, high-bandwidth, pitch-angle resolved measurements. With the success from a new three-channel near-vertical-view current...
