The frequency of the free oscillation is determined by the mass of the object and the gradient of the ultrasonic radiation force. Using this phenomenon, in this report, we tried to measure the mass of ...
Each group consisted of 4 samples from each management system and SF. After drying and measuring the dry soil mass, and determining BD by the CrM, the samples were carefully removed from the ...
Abstract: In a Kibble balance experiment, the mass value is determined by calculating the geometric factor of the magnetic circuit - coil set up. This factor is calculated using two different ...
THE mass spectrometer is often used for the measurement of the appearance potentials of ions produced by electron bombardment of gaseous molecules. For this purpose, two gases are admitted to the ...
Objective Although dual-energy X-ray absorptiometry (DEXA) is the preferred method to estimate adiposity, body mass index (BMI) is often used as a proxy. However, the ability of BMI to measure ...
