Purpose Acetophenetidin can be formed through two methods‚ Williamson ether synthesis and amide synthesis. By working in groups of two we were able to complete both methods of synthesis routes. The end result should be the synthesis of a similar product‚ by verification between the two individuals. Reaction Experiment and Observations Amide Synthesis of Acetophenetidin The Synthesis reaction began by removing the colored impurities from the p-phenetidine‚ accomplished by mixing

One of the most known theories is the Activation Synthesis Theory. J. Allan Hobson developed this theory in the late 1970s after running an experimental study on cats focusing on rapid eye movement sleep (REM) (Domhoff‚ 2003). The Activation Synthesis Theory simply states that our cerebral cortex is trying to interpret random electrical activity we have while sleeping. Hobson argued and quoted that

During‚ the period of the eighteenth century to the nineteenth century the Europeans held a strong belief in scientific proof. The belief in scientific proof is associated to the Age of Enlightenment‚ a period in Europe in which people thought their beliefs should depend on reason and scientific proof. This period is referred to a time when people “set out by means of reason and direct observation to discover the fundamental laws governing nature‚ humanity‚ and society. The Enlightenment Philosophers

Purpose: This experiment is used to perform a series of synthesis reactions that convert aluminum foil to alum. Alum is used in cooking‚ to treat wastewater‚ and is used in common deodorant. In this lab a series of four reactions will occur to yield alum. Calculations: Aluminum foil: 0.5035 grams Alum & Watch Glass: 21.7691 grams Watch Glass: 15.1560 grams Alum: 6.6131 gram Theoretical Yield of Alum: 2Al(s) + 2KOH(aq) + 4H2SO4 + 22H20 -> 3H2(g) + 2KAl(SO4)2 + 12H2O(s) 0.5035gAl

Epigenetics is the series of chemical modifications of DNA and its connected proteins that contain phenotypic information during cell division. These modifications alter gene expression without changing DNA sequence. They differ among tissues and change over throughout the organism’s lifetime. A well-understood example of epigenetic modification is DNA methylation‚ the process by which a methyl group is covalently bonded to cytosine. During DNA replication‚ a specific enzyme recognizes unmethylated

Three hundred day old ducklings‚ (100 Cherry valley ducks‚ 100 Moulard and 100 Pekin) allotted into indoor group; where ducklings within each breed were brooded and reared without any outdoor access until they were slaughtered and outdoor group; where ducklings were allowed to an outdoor access from 3rdweek of age. The obtained results showed that Cherry valley ducks exhibited high percentage of feeding‚ drinking‚ panting and total body care behavior than Moulard and Pekin. Total confinement of ducks
