In the study "The analysis of ultrasonic transducers using the finite element method", we are focusing on building a finite element model of the ultrasonic transducer in Abaqus. The numerical modeling for dynamical behaviors of the ultrasonic transducer is presented and shown very close to the actual sample value.

This specification covers the procedure for longitudinal Charpy V-notch testing of structural steel and contains two frequencies of testing. The impact properties of steel can vary within the same heat and piece, be it as rolled, control rolled, or heat treated. The purchaser should, therefore, be aware that testing of one plate, bar, or shape does not provide assurance all plates, bars, or shapes of the same heat as processed will be identical in toughness with the product tested. Normalizing or quenching and tempering the product will reduce the degree of variation.

Microwave absorbing materials (MAMs) are essential materials for mitigating the bad effects of electromagnetic interference and microwave pollution. SrFe12-2xCux/2Cox/2TixO19 samples showed their superior microwave absorption performances in both reflection loss and effective absorption bandwidth (EAB) values for the normal incident angle of the microwave. Between these parameters, EAB values expressed how large a frequency the MAM could be used for practical applications.

Sampling frequency plays important role in water quality monitoring activity. A suitable sampling frequency could save time and cost of monitoring work. In this study, coastal seawater quality of the Northeast of Quang Ninh Province, Vietnam was evaluated by single indicator and statistical analysis of the monitored data from 2016–2019.

Spontaneous triploidy has been reported in a number of fish species, and is often linked with in vivo or in vitro ageing of eggs post ovulation. Here, we provide the first investigation into the frequency of spontaneous triploidy in farmed Atlantic salmon by analysing more than 4000 fish from 55 farms, and approximately 1000 recaptured escapees, all sampled in the period 2007–2014.

In this paper we investigate de novo deletions defined as DNA segments missing in an oral cleft proband but present in both unaffected parents. We compare de novo deletion frequencies in children of European ancestry with an isolated, non-syndromic oral cleft to frequencies in children of European ancestry from randomly sampled trios.

The frequencies of apolipoprotein L1 (APOL1) variants and their associations with chronic kidney disease (CKD) vary substantially in populations from Africa. Moreover, available studies have used very small sample sizes to provide reliable estimates of the frequencies of these variants in the general population.

In this work, we carried out a study on NiTiO3 nanomaterial synthesized via citrategel method. The structural characteristics were determined by basic X-ray diffraction analysis. SEM analysis showed the surface morphology of the sample. The impedance spectra analysis was used to elucidate the dependence of complex impedance values on temperature and frequency.
