This paper deals with the detailed phytochemical evaluation of the stem of Eclipta alba (Bhringaraja) family: (Compositae). The preliminary phytochemical screening shows that different extracts of plant have different constituents like carbohydrate, alkaloids, phenolics, steroids, glycosides, fat and oils. TLC of the hexane extract after column extraction was shown Rf value 0.78 in Petroleum ether:Hexane:Chloroform:Methanol, used as mobile phase in 2:4:2:1 ratio and TLC of pet. Ether extract also shown Rf value is 0.72 in Petroleum ether:Hexane:Chloroform, used as mobile phase in 4:3:1 ratio after column extraction. This is evaluated by the instrumental analysis (UV, IR, and NMR) of hexane and pet. Ether extract. They shows consequently that pet. Ether extract contains alkane (2940 Cm-1, δ 0.827), alkene (1630 Cm-1, δ 1.253-1.351), monomer of aliphatic acid (1760 Cm-1 δ 2.169), aromatic amine (1570 Cm-1, δ 2.593) etc. and hexane extract contains alkane (2940 cm-1, δ 0.801-0.873) alkene (1625 Cm-1, δ 0.988-1.075) aldehyde (1740 Cm-1, δ 2.154 – 2.288) and aromatic alcohol (1110Cm-1, δ 5.324). These data suggests that the extracts (pet. ether and hexane) may have the glycoside, aliphatic acid, steroids, fats and oils. They are pharmacologically important.Keywords

There are about 400 tribal groups in India constituting about eight per cent of the Indian population (Census India, 2001). Wide variations have been noted concerning their food habits from place to place. Though their population is mainly concentrated in the Northern states of the country like, Maharashtra, Bihar, Orissa, Jharkand and Madhya Pradesh, the State of Tamil Nadu also has several tribes scattered In various districts. Vellore district located in Tamil Nadu has few tribes namely, Malayalis, Kattu Naicker, Gonda Reddy and Irulars. Among them, Malayalis and Irulars comprise the major part. There are 1070 tribes living in K.V. Kuppam Block, (Census India, 2001) which includes Irular, Kattu Naicker and Gonda Reddy.- Nutritional Profile of Rural Adults from Vellore District of Tamil Nadu

To prevent adults from becoming physically and psychologically under developed, several programes have been implemented in India to address the issue of malnutrition. However, malnutrition and its effects hove not significantly subsided. Researchers find that poor and undernourished communities, especially those of rural India, are trapped in a vicious cycle, where malnutrition is passed from generation to generation due to a number of inequities.- Impression Creep Behaviour of Extruded Mg-Sn Alloy

Mg-Sn alloys contain thermally stable Mg2Sn phase, and are proposed as heat-resistant alloys for automobile engine applications. In this study, the creep behaviour of Mg-5Sn alloy was investigated using impression creep technique. The impression creep tests were carried out under constant punching stress in the range of 80-320 MPa at temperatures 373-573 K, for dwell times up to 5 hours. The results highlight that creep of Mg-5Sn alloy was load and temperature dependent, i.e. increasing the load and temperature resulted in larger creep deformation and hence to higher creep rates. From the creep curves, the stress exponent and the activation energy were estimated and the creep mechanism was identified.Keywords

Introduction: Irrigants play an important role in debridement and disinfection of ischolar_main canal space. Precipitate formed from combination of irrigants during ischolar_main canal treatment may affect the properties of intracanal medicaments and adaptation of obturated materials to the ischolar_main canal walls.
Aim: To check for precipitate formation from various irrigant combinations and to weigh the amount of precipitate formed.
Methods and Material: Five different irrigants namely 2% CHX gluconate, 3% NaOCl, 5% Neem, 5% Aloevera, and 5% Garlic were taken in different test tubes. 1mL each of two different irrigants were mixed in 10 test tubes and observed for 2 min for formation of any precipitate and the formed precipitate was weighed.
Results: 1mL 2% CHX + 1mL 3% NaOCl and 1mL 2% CHX + 1mL 5% Neem showed precipitate formation immediately. Through statistical analysis it was observed that more amount of precipitate was seen in 1mL 2% CHX + 1mL 5% Neem followed by 1mL 2% CHX + 1mL 3% NaOCl.
Conclusion: Precipitate formation is seen more with the 2% CHX‐5% Neem when compared with the control group (2% CHX-3% NaOCl).
