development of ultrasound technique has not been progressing for evaluating the internal quality of fruits as fast as that of processed foods. in this research for quality assessment of pear fruit (shah miveh variety) an ultrasonic measurement system was constructed to transmit and receive the ultrasonic waves. the apparatus included a pulser-receiver, a pair of 75 khz ultrasonic transducers wi...

A simple method for organically modifying a natural acid clay (Japanese clay) rapidly with alkylamine has been developed. Japanese mainly consists of acidic montmorillonite and was successfully modified decylamine in water at room temperature short time period (10 min) using an ultrasonic bath without any pretreatments. The structure the changed from exterior surface modification to intercalati...

The intensification of ultrasonic vibrations for the processing agricultural products is becoming increasingly important in food industry, as it can reduce energy consumption dehydration raw materials. research aims to study effect sonication on change electrophysical parameters and structure apple materials process combined drying using direct electric heating. Using scanning electron microsco...

background: the newborn’s first bath, performed in neonatal intensive care units (nicu), is believed to be a stressful situation, especially for the premature infants. as a developmental care approach, swaddle bathing is a low-stress bathing method for vulnerable preterm neonates. given the limited number of the studies examining this bathing method, the present study was conducted with the aim...

Porous ultra-high-temperature ceramics (UHTCs) are a candidate group of materials for transpiration cooling hypersonic vehicles due to their exceptionally high melting point, typically above 3000 K. Their operating temperature permits higher amount radiative than that achievable with conventional materials, which reduces the required coolant mass flow rate cool surface. This work experimentally...
