The number of persons with implanted cardiac pacemakers (PM) has increased in Western countries. The aim of this paper is to investigate the possible situations where persons with a PM may be exposed to extremely low frequency (ELF) electric (EF) and magnetic fields (MF) that may disturb their PM. Based on our earlier studies, it is possible to find such high public exposure to EFs only in some...
Recent trends in electric meter is based on Global System for Mobile Communication(GSM), Radio Frequency Identification(RFID), Remote wireless energy measurement from meter. But none have turned to solve the problems related to power demand. In this paper, we propose a solution to solve the problems associated with power demand by designing an electric meter that efficiently handles the power c...
self-reported measures of dietary intake are prone to measurement error that may obscure the relationship of diet and disease. this review addresses strategies to decrease errors during collection of dietary data and statistical approaches to deal with measurement issues once the data are collected. examples from two us studies-- the women’s health initiative (whi) dietary modification trial a...
To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, cont...
This paper presents a new acoustic-resonance microscopy, electromagneticresonanceultrasound microscopy (ERUM), to evaluate the localized elastic constant of a solid material. It is based on the resonance-frequency shift of a vibrating oriented langasite (La3Ga5SiO14) crystal contacting the specimen via a sphere tip. The vibration of langasite is excited and detected by a dynamic electric field ...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
Contemporary cochlear implants with multiple electrode stimulation can produce good speech perception but poor music perception. Hindered by the lack of a gold standard to quantify electric pitch, relatively little is known about the nature and extent of the electric pitch abnormalities and their impact on cochlear implant performance. Here we overcame this obstacle by comparing acoustic and el...
[1] We report results of a field campaign conducted in the Nevada desert with a suite of electric field instruments consisting of a field mill (FM) and a short dipole antenna (SDA). Furthermore, we show that a combination of the measurements of these two instruments allows the estimation of the electric resistivity of air, an important quantity that is extremely difficult to measure near the Ea...
