An ultracentrifuge experiment was performed on a pure liquid-indium at centrifugal acceleration field of 8.2x10 g at 300°C for 100 hours. The isotope ratio measurements were performed on the centrifuged specimen, which was cooled and solidified before release the acceleration, with Secondary Ion Mass Spectrometer (CAMECA IMS-6f). In/In isotope ratio on the specimen changed with negative gradien...
Technology can provide safety in physical practices and improving the performance of these activities, so manufacturing of equipments for these purposes has been considered widely. The aim of the present paper was design and fabrication of three-axis accelerometer. hree acceleration sensors, three gyroscopes for angular velocity measurement, a microcontroller for converting analog data to ...
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...
The effects of seat-back angle and accelerometer height at the seat-back on seat-back x-axis frequency-weighted root-mean-square (r.m.s.) acceleration have been investigated in field experiments. Experiment 1 investigated the range and variability, of frequency-weighted r.m.s. acceleration at the same measurement position, where the seat-back angle was 24 degrees from vertical on the floor and ...
