The plants of genus Cordia comprise of trees and shrubs which are widely distributed in warmer regions. The plants of this species have long been used in traditional and folk medicine for treating various illnesses. Some plants in this species were exhaustively explored and some others are yet to be. Substantial progresses on their chemical and pharmacological properties of some species have been made. In India, the fruits of this species are consumed as vegetable. The pharmacological studies carried out with extracts and purified compounds indicates that the plants of Cordia species posses analgesic, anti-inflammatory, antimicrobial, antiviral and antifertility activities. Various compounds like flavonoids, triterpenes, tannins, alkaloids and fatty acids possessing wide range of bioactivities were isolated from different plant parts of Cordia species. Based on these reports it is clearly indicated that the plants of Cordia genus possess potential therapeutic actions.Keywords

Transferring materials from a higher place to a lower place is a challenging task. Conveyers, lifts and many more material handling devices are difficult to construct, install and operate. Thus a simple gravity based zig-zag material handling system which requires no external power to drive them has been developed. The buckets which are used are made to rotate about a certain axis thereby enabling them to transfer the materials efficiently. This system can be used in places where the space is limited. The system has been modeled using SOLIDWORKSTM and simulated using MSC ADAMSTM. A prototype has been made which shows how the system works. The results indicate that it is an efficient way for material transfer in vertical direction. It can be used in industries and machining centers where there are multi floors and materials need to be transferred from top to bottom floors.Keywords

Biodiesel production using marine microalgae as an alternate fuel source is receiving international attention in view of its economic and environmental advantages. The present study evaluated the feasibility of biodiesel production from the marine microalgae; Chlorella vulgaris (NIOT-74). Outdoor mass cultures of marine microalgae were done in different photobioreactors and raceways with marine C. vulgaris (NIOT- 74) as a model organism. The study demonstrated the feasibility of producing biodiesel and provided an evaluation of the physico-chemical properties of biodiesel (B100) and blend (B10) according to ASTM standards. A cost-effective electroflocculation method with 90.12% harvesting efficiency was developed and tested. The biodiesel produced from C. vulgaris (NIOT-74) was tested in two-stroke and four-stroke engines and was also used to test drive a vehicle.Keywords
