Rafael Christian L. Bojador Environmental Science CAS-01-401P “Is the world overpopulated?” Facts: Overpopulation is a generally undesirable condition where an organism’s numbers exceed the current carrying capacity of its habitat. The term often refers to the relationship between the human population and its environment‚ the Earth‚] or smaller geographical areas such as countries. Overpopulation can result from an increase in births‚ a decline in mortality rates‚ an increase in immigration

Measure the initial temperature of water and record. 8. Using the pipette put about a pipettes worth of ethanol into the crucible. 9. Place the crucible on top of the tripod and under the calorimeter and light the ethanol. 10. Put the polystyrene cover over the calorimeter and stir the water gently. 11. When all ethanol has burned out record the highest temperature reading on the thermometer. 12. Record the temperature difference. 13. Do not change the water. 14. Set up

solid with extremely low density and thermal conductivity. Nicknames include "frozen smoke"‚ "solid smoke"‚ "solid air" or "blue smoke" owing to its translucent nature and the way light scatters in the material; however‚ it feels like expanded polystyrene (Styrofoam) to the touch. Aerogel was first created by Samuel Stephens Kistler in 1931‚ as a result of a bet with Charles Learned over who could replace the liquid in "jellies" with gas without causing shrinkage. Aerogels are produced by extracting

Synthesis of terpolymer PLGC: The terpolymer PLGC was synthesized using a reported procedure with a starting monomer ratio of 70:20:10 of L-LA‚ GL and Ɛ-CL respectively using the catalyst tin(II)2-ethyl hexanoate. The chemical reaction is given in the figure1. The yield % of the synthesized polymer was calculated by the equation: Yield %= (Weight of synthesized polymer)/(Weight of the monomers taken) ×100 Characterization of synthesized polymer: Chemical analysis using Fourier transform infrared

INTEGRATED PRODUCT DEVELOPMENT AND STRATEGIES ASSIGNMENT – I S.SATISH BABU 11MD34 RAPID PROTOTYPING Rapid prototyping is the automatic construction of physical objects using additive manufacturing technology. The use of additive manufacturing for rapid prototyping takes virtual designs from computer aided design (CAD) or animation modeling software‚ transforms them into thin‚ virtual‚ horizontal cross-sections and then creates successive layers until the model is complete. It is a
