This paper describes an engineering application of electromagnetic field (EMF) treatment to mitigate biofouling in seawater-cooled tubular heat exchanger-condensers. After allowing a biofilm to stabilize, EMF treatment was applied and was reported to precipitate dissolved ions and contribute to partial…

Jan 1, 2014
This study assessed and compared total RF-EMF exposure for a mobile-phone user in an office environment when connected to an indoor femtocell base station versus a conventional macrocell base station. Using a framework that combines near-field and far-field exposure, the authors report a 20–40× reduction in total…
Spatial learning, monoamines and oxidative stress in rats exposed to 900 MHz electromagnetic field in combination with iron overload.

RF Safe Research Library
Jan 1, 2014
This animal study tested whether 900 MHz EMF exposure, alone or combined with brain iron overload, affects cognition and brain biochemistry in Long-Evans rats. EMF-exposed rats showed impairment in an object exploration task and changes in monoamine content (notably in the hippocampus), while other spatial…
Symptom attribution and risk perception in individuals with idiopathic environmental intolerance to electromagnetic fields and in the general population.

Jan 1, 2014
This cross-sectional study compared EMF-related health perceptions and symptom attribution among self-identified EMF-sensitive individuals from an internet panel, non-sensitive individuals, and an NGO-recruited IEI-EMF group. The internet-panel sensitive group reported more non-specific symptoms, higher perceived EMF…
Study on effective improvement of mobile phone sound quality in a noise environment for the hearing-impaired.

Jan 1, 2013
This study evaluated whether the NAL-NL1 hearing-aid fitting formula is appropriate for hearing-impaired mobile communication, comparing it with a modified fitting formula. Speech materials were low-pass filtered at 8 kHz and presented through a mobile phone for word-recognition testing in quiet and noisy conditions.…
Are media warnings about the adverse health effects of modern life self-fulfilling? An experimental study on idiopathic environmental intolerance attributed to electromagnetic fields (IEI-EMF).

Jan 1, 2013
This randomized experiment tested whether a TV report warning about WiFi health effects could influence symptoms during a subsequent sham WiFi exposure. Over half of participants reported symptoms attributed to the sham exposure, and the warning film increased EMF-related worries. Among participants with higher…
Efficiency of radiofrequency assisted uvulopalatopharyngoplasty in the treatment of snoring.
Research

Jan 1, 2011
This pre/post clinical study evaluated radiofrequency-assisted uvulopalatopharyngoplasty for snoring using polysomnography before and after surgery in 22 patients. The abstract reports a statistically significant postoperative reduction in snoring, with most patients showing decreased snoring index. The work concerns…
An extension of the Czjzek model for the distributions of electric field gradients in disordered solids and an application to NMR spectra of 71Ga in chalcogenide glasses.

Jan 1, 2010
This paper discusses the Czjzek model for distributions of electric field gradient (EFG) tensors in disordered solids and highlights its underlying assumptions and characteristics. It then introduces an extended model that combines a defined local EFG environment with an adjustable Gaussian (Czjzek) noise term to…
Radiofrequency microtenotomy for the treatment of plantar fasciitis shows good early results.

Jan 1, 2010
This small clinical case series evaluated TOPAZ radiofrequency coblation microtenotomy for recalcitrant plantar fasciitis in 14 patients. The abstract reports improved AOFAS hindfoot scores at 3 and 6 months and improvements in several SF-36 domains, with most patients reporting good-to-excellent satisfaction. The…

This SCENIHR Opinion updates earlier 2009 SCENIHR documents on EMF health effects and research needs, focusing on new information and remaining knowledge gaps. The abstract primarily characterizes sources and patterns of exposure across static, ELF, IF, and RF fields in both public and occupational settings. It notes…
Mitomycin C-associated radiofrequency microelectrocautery used in myringotomy in an animal model.

This experimental animal study compared tympanic membrane closure time after myringotomy performed by microknife versus radiofrequency microcautery, with and without mitomycin C. Radiofrequency myringotomy differed significantly from knife myringotomy, and the 0.7 mm radiofrequency tip combined with mitomycin C was…
