The one-dimensional analytical approach is developed to predict and analyze the acoustic attenuation performance of three-pass perforated tube muffler with perforated bulkhead(s) and validated by comparing the transmission loss results from one-dimensional analytical approach and finite element method.The one-dimensional analytical approach is then
The combination of GTAW (Gas Tungsten Arc Welding) and SMAW (Shield Metal Arc Welding) processes on SA537 Class 2 carbon steel using variations of heat input is the main choice to get the best quality welded joints.This research aims to joint SA537 Class 2 material using the GTAW and SMAW process with heat input variations sophie allport zebra to g
According to the properties of the pine tree trunk and its wide range of applications, finding its defects can play a vital role in reducing costs.Since the arrethe bush balm ultrasonic test is a non-destructive method, this method is an appropriate alternative to find defects in the pine tree trunks.Optimizing the ultrasonic non-destructive test i
Viral vectors are being engineered to deliver CRISPR/Cas9 components systemically in plants to induce somatic or heritable site-specific mutations.It is hypothesized that RNA mobility signals facilitate entry of viruses or single guide RNAs (sgRNAs) into the shoot apical meristem where germline mutations can occur.Our objective was to understand th
Brassica rapa can eavesdrop on volatile compounds emitted from peppermint and consequently boost its defense responses against Plutella xylostella.In the current study, to assess how B.rapa receiver plants cultivated near peppermint plants resist P.xylostella, two biological assays were conducted.The data showed that the receiver plants cultivated
