Study on preparing fatty acid by hydrolyzing Jatropha Curcasl Oil with lipase
Used tween-80 as emulsifier, industrial lipase as catalyst to hydrolyze Jatropha Curcasl Oil and make mixed fatty acid. We discussed the enzyme concentration, substrate concentration, temperature and time on hydrolysis. Through the experiment, we found that when we used emulsifier which contains 2% oil in the system, we could get the optimal parameter for hydrolysis of waste oil from restaurants as follows: concentration of catalyst 4% (W/W), weight ratio of oil to water 1:4 (W/W), temperature at 40°C, and hydrolysis time is 32h. Under these conditions, the AV(acid value) of hydrolyzed rapeseed oil reached 163.2 mg KOH/g, and hydrolytic rate arrived at 89.6%.

The Last Days of Socrates
'Consider just this, and give your minds to this alone: whether or not what I say is just'. Plato's account of Socrates' trial and death (399 BC) is a significant moment in Classical literature and the life of Classical Athens. In these four dialogues, Plato develops the Socratic belief in responsibility for one's self and shows Socrates living and dying under his philosophy. In "Euthyphro", Socrates debates goodness outside the courthouse; "Apology" sees him in court, rebutting all charges of impiety; in "Crito", he refuses an entreaty to escape from prison; and in "Phaedo", Socrates faces his impending death with calmness and skillful discussion of immortality. Christopher Rowe's introduction to his powerful new translation examines the book's themes of identity and confrontation, and explores how its content is less historical fact than a promotion of Plato's Socratic philosophy.
