Non-destructive detection and evaluation of invisible cracks in metal structures is an important matter in several critical environments including ground transportation, air transportation and power plants. In this paper, a high-Q near-field Microwave probe is designed and fabricated using defected ground structures for surface and subsurface crack detection in metal structures. For this purpos...

Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor.  SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...

conclusions the in-house 1 step taqman real time rt-pcr assay showed acceptable performance characteristics. our study presents the robustness and cost-effectiveness of the method for detection and quantification of hcv rna. methods the primers and probe were selected from a highly conserved region of the hcv genome, which allowed the detection of 4 common hcv genotypes in iran. using 4 quantif...

original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...

corophium volutator (pallas) has been recommended by the paris commission as one of the standard species for testing chemical used in offshore oil and gas exploration/production. in the present study, gut contents of corophium volutator have been analysed by electron probe microanalysis (epma) for baso4 and other heavy metal impurities after exposure tto spiked sediments following a standard as...

purpose : to report a patient with retained broken probe tip in the false passage site after nasolacrimal duct (nld) probing case report : a 18-month-baby with epiphora and a nontender mass in the site of lacrimal sac was visited in clinic. she had a history of probing six months ago by another ophthalmologist. the probing was repeated successfully but the mass size didn’t change. the mass was ...

background: the purpose of this study was to compare the effi cacy of endovac irrigation system and side-vented closed ended needle (max-i probe) in removing smear layer from root canals at 1 mm and 3 mm from working length using protaper rotary instrumentation. materials and methods: a total of 50 freshly extracted maxillary central incisors were randomly divided into two groups after complete...
