A novel approach for assessments of radiofrequency electromagnetic fields exposure in buildings near telecommunication infrastructure

Research RF Safe Research Library Jan 1, 2025

This paper proposes a new methodology to better assess indoor RF-EMF exposure in buildings near telecommunication base station antennas by refining measurement-point selection. Implemented in four multi-storey buildings in Natal, Brazil, indoor electric field peaks and averages were reported to be substantially…

Effect of Extremely Low Power Time-Varying Electromagnetic Field on Germination and Other Characteristics in Foxtail Millet (Setaria italica) Seeds.

Research RF Safe Research Library Jan 1, 2020

This study evaluated extremely low, time-varying EMF “magneto-priming” to optimize germination in foxtail millet seeds using a central composite design and response surface methodology. The authors report optimal germination at 10 Hz, 30,007 nT, and 30 minutes, with improvements in germination percentage and multiple…

Electromagnetic Field Assessment as a Smart City Service: The SmartSantander Use-Case.

Research RF Safe Research Library Jan 1, 2017

The study presents a smart city service for electromagnetic field assessment using deployed measuring probes integrated into a city platform. Data collected for more than one year are processed to characterize E-field levels across large areas and over time. The authors report that the results validate the…

Fundamental study on a gene transfection methodology for mammalian cells using water-in-oil droplet deformation in a DC electric field.

Research RF Safe Research Library Jan 1, 2016

This paper describes an in vitro gene transfection technique termed water-in-oil droplet electroporation, using an intense DC electric field to deform a droplet between electrodes. The deformation can cause an instantaneous short circuit, during which transient membrane pores are reported to form and permit exogenous…

Visualizing radiofrequency lesions using delayed-enhancement magnetic resonance imaging in patients with atrial fibrillation: A modification of the method used by the University of Utah group.

Research RF Safe Research Library Jan 1, 2015

This feasibility study evaluated whether delayed-enhancement MRI (DE-MRI) using commercially available tools could visualize radiofrequency ablation lesions in Japanese patients with atrial fibrillation. Of 15 scans, 3 were uninterpretable due to low image quality, and lesions were visualized in 8 of the remaining 12…

Analysis of DPPH inhibition and structure change of corn peptides treated by pulsed electric field technology.

Research RF Safe Research Library Jan 1, 2015

This laboratory study evaluated how pulsed electric field (PEF) processing affects antioxidant activity and structure of 10–30 kDa corn peptides. Antioxidant activity was assessed via DPPH inhibition and optimized using response surface methodology. Under reported optimal conditions (10 mg/mL, 15 kV/cm, 2,000 Hz),…

High-intensity pulsed electric fields processing parameters affecting polyphenoloxidase activity of strawberry juice.

Research RF Safe Research Library Jan 1, 2010

This study evaluated high-intensity pulsed electric fields (HIPEF) as a processing method to inactivate polyphenoloxidase (PPO) in strawberry juice. Using response surface methodology at a constant electric field of 35 kV/cm, the authors report strong PPO reductions across tested parameter ranges. Bipolar mode,…

Aerodynamically assisted bio-jets: the development of a novel and direct non-electric field-driven methodology for engineering living organisms.

Research RF Safe Research Library Jan 1, 2007

This paper describes an aerodynamically assisted bio-jetting technique that processes living cells/organisms using differential pressure rather than an electric field. The authors report an operational window for stable jetting and near-monodispersed cell-bearing droplets. Cell viability after jetting was evaluated…
