Abstract

Plants have been the basis of many traditional medicines throughout the world for thousands of years and continue to provide new remedies to mankind. Anacardium occidentale belongs to the family Anacardiaceae. The leaves possess antidiabetic, antiulcer, anti-inflammatory activities. Present work aims to highlight the pharmacognostical and phytochemical, standards of leaves of A. occidentale. The ethanolic extract was prepared by soxhlet apparatus . The total ash value, acid insoluble ash value, water soluble ash value, extractive values, loss of drying, fluorescence characters and phytochemical studies were performed. The total ash value, acid insoluble ash value, and water soluble ash value were found 4.85%,0.97% and 4.9% respectively The screening revealed the presence of alkaloids, flavanoids, tannins, carbohydrates, steroids and absence of saponins in the ethanolic extract of A. occidentale. The findings are useful in establishing a relationship between chemical composition of the leaf extract and previously reported activities of A. occidentale.

Abstract

Today's higher education is one of the needs of any students for growing his life.One of the biggest challenges with higher education is thatinstitutions would like to know, which students will enroll in which course, and which students will need more assistance in particular subject and what efforts should be taken for weak students.Data mining is one of the powerful tools to extract knowledge from large educational database and it can be used for decision making in educational system.

In this paper data mining techniques such as clustering,Association, Rule mining etc. based work is analyzed which will give direction to the educational institution for improving performances of their students. This review also helps to researchers for choosing appropriate data mining techniques to analyzed student data.

Keywords

Abstract

Nanofluids have unique features different from conventional solid-liquid mixtures which have millimeter or micrometer sized particles dispersed in some base fluid. Due to their excellent characteristics, these new types of fluids have attracted wide interest in recent years. It is found that nanofluids have significantly higher thermal conductivity than the base fluids. In this work we focus on the ultrasonic and thermal properties of nanofluids. Nanofluids containing copper nanoparticles with base fluid polyvinyl alcohol (PVA) have been developed in our laboratory. These nanofluids are characterized by UV-Visible spectroscopy, X-ray diffraction (XRD) and transmission electron microscopy (TEM). Temperature dependent ultrasonic velocity and ultrasonic attenuation measurements are performed for different concentration of the copper nanoparticles in the PVA. Hot Disk Thermal Constant Analyser is used for the measurement of the thermal conductivity of synthesized nanofluids. Experimental results show that the thermal conductivities of the nanofluids are higher than that of base fluid PVA. The obtained results were analyzed taking into account the ultrasonic and thermal behavior of matrix and particles. Possible mechanism for the enhancement of thermal conductivity of the nanofluids using theoretical model is also discussed.
