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...

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...

In this article, the synthesis of magnetite nanostructures was successfully carried out by sonochemical process. method, stoichiometric amount iron chlorides (FeCl3.6H2O and FeCl2.4H2O), ammonia (NH3) polyvinylpyrolidone (PVP) were used to synthesize pure Fe3O4 nanoparticles. The effect initial sonication power ultrasonic device on size morphology final products as one effective parameters inve...

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...

Lowering Intraocular pressure (IOP) is a main therapeutic objective in glaucoma patients because IOP an important risk factor for progression. The of this work was to formulate and evaluate, vitro vivo, stable effective Solid Oil (S/O) topical formulation the antiglaucoma drug, timolol maleate (TM). S/O dispersions were prepared by emulsification aqueous TM solutions cyclohexane using different...

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...
