A rapid and efficient method for the synthesis of bis-thiazolidinones has been achieved by pseudo five-component reaction of aldehydes, ethylenediamine and thioglycolic acid in the presence of nano-NiZr4(PO4)6 as catalyst under microwave irradiation. Nano-NiZr4(PO4)6 has been characterized by powder X-ray diffraction, scanning electronic microscopy (SEM), energy dispersive spectroscopy (EDS), v...

background: antibiotic residue in food is a major concern from a health point of view. post-slaughter and pre-consumption processing such as cooking could affect residue. objectives: the purpose of this study is to survey the effect of boiling and microwave on tilmicosin in chicken. methods: chicken samples containing different tilmicosin amounts cooked in boiling water and in the microwave. af...

Due to the complicated structure of microwave radiometric imaging system and the massive amount of data collection in one snapshot, it is difficult to achieve the high spatial resolution image by conventional microwave radiation imaging method based on the Nyquist sampling. In this paper, according to the priori information of the compressible multi-structural information of microwave radiation...

The paper describes a novel method of drilling into hard non-conductive materials by localized microwave energy (US patent 6,114,676). The Microwave Drill implementation may utilize a conventional 2.45GHz magnetron, to form a portable and relatively simple drilling tool. The drilling head consists of a coaxial guide and a near-field concentrator. The latter focuses the microwave radiation into ...

BACKGROUND AND AIM Pathologists are under constant pressure for instant and reliable diagnosis. The manual procedures employed in private laboratories and institutional setup for histoprocessing and staining are laborious and intense. Thus, this study aims to evaluate and compare the microwave tissue processing and staining with the conventional methods which are in vogue. MATERIALS AND METHO...

This paper provides an alternative and highly accurate method in predicting Small Signal Performance of Microwave Amplifier. An Electromagnetic (EM) simulator that based on Finite Element Method (FEM) was used in combination with the conventional SPICE-based microwave circuit simulator in order to demonstrate the superiority in performance outcome such as Rollet Stability Factor (K), Return Los...

Microwave radiometric method is discussed as applied to monitoring of rice growth. The following questions are considered in the paper. Modeling of microwave emission from rice fields. Experimental studies of microwave emission from rice fields. Rice biomass retrieval from microwave radiometric measurements. Examples of monitoring of rice growth with airborne and ground based radiometers.

The purpose of this research work was to investigate the optimum operating conditions for biodiesel production from castor oil using a microwave. The Box–Behnken design of experiment was carried out using the Design Expert 7. A response surface methodology (RSM) was used to analyze the influence of the process variables (molar ratio of methanol to castor oil, catalyst concentration, reaction ti...
