Influence of cutting parameters on chatter and tool wear during end milling of stainless steel conducted on VMC
Published 2002“…The performance of the tool is evaluated from the point of view of its wear intensity, mechanism of failure and generation and effect of chatter on tool wear and vice versa. The investigations were aimed at determining the effect of cutting parameters, specifically cutting speed, feed and depth of cut, on chatter amplitude, tool wear rate, mechanism of tool wear and using these data and machined surface roughness values from previous work to come up with recommended values of cutting parameters for semi-finish and finish end milling operation of stainless steel work materials. …”

The diversity of amphibian species in urban lake as ecological indicator for healthy aquatic environment
Published 2015“…Results showed that six amphibian species of Duttaphrynus melanostictus (Common Sunda Toad), Hylarana erythraea (Green Paddy Frog), Polypedates leucomystax (Four-line Tree Frog), Fejervarya cancrivora (Crab-eating Frog), Microphyla heymonsi (Dark sided chorus frof) and Fejervarya limnocharis (Indian Rice Frog) were observed. The highest species of amphibian recorded were Hylarana erythraea with (n=80) which were found at all stations of Wetland 2 (largest wetland) and two stations at Wetland 3 (natural wetland), while others were less than (n=10). …”
