Abstract

A study was taken up to evaluate the relationship between the sensory perceived acidity and instrumentally measured acidity in thirteen coffee samples representing the two major commercially cultivated coffee varieties viz., Coffea arabica (arabica coffee) and C.canephora (robusta coffee) in India. The acidity level in these coffee samples was assessed by three ways viz., organoleptic (sensory perceived) scoring, pH meter and titratable acidity. The results of this study revealed that acidity level assessed by the organoleptic scoring matched with the acidity level measured by pH meter and titratable assay method. Statistical analysis of these results indicated there was close correlation between sensory perceived acidity and instrumentally measured acidity as evidenced by the correlation coefficient (r²) value ranging from 0.86 to 0.99.

Abstract

In presently world there are lot of Disable people living, it is very difficult to face day to day life in a computation world. Mainly they are depend on Wheelchair to survive in a society. In present wheelchair it is very difficult while moving on a slope. If chair moving up the slope there is possibility that the person will fall backward and if chair is moving down the slope then the person will fall front side of chair. In this project we are providing solution for this problem. And we are using hydraulic system for tilting a seat. This will provide comfortable while moving on a slope, like if moving in a downward we can tilt the seat backward with some inclination similarly in moving in upward we can tilt the seat downward with some inclination. This will provide smooth movement for a user with good economy.
