    Abstract: In this study, five derivatives of 2-thiobarbituric acid were prepared under microwave irradiation (MWI) and conventional heating method. It was found that the preparation time wasreduced from 24 hours to 5-10 minutes by using microwave irradiation method. In microwave irradiation, the yield also comparatively very high (97.50-98.32%) than conventi... Show More

    Abstract: Crude oils have components such as metals, pigments, phospholipids and waxes, which alter its physicochemical and organoleptic characteristics. These components are commonly removed during the refining process by physicochemical methods. In recent decades, the oil industry has desired the development of biotechnological processes to replace traditi... Show More

    Abstract: We consider axon as a cylinder that has acoustic waveguide regimes to concentrate the propagated signals with appropriate deformation of membrane areas. The highest temperature results near the cylinder axis that can cause low-frequency (0.1 - 10 kHz) longitudinal vibrations of axon due to thermal expansion of material. These frequency shifts are v... Show More
