April Jean Delos Santos BBF 2-9s 1. What is the significance of studying the different worlds as experienced by poets‚ dramatist‚ essayist‚ storytellers‚ playwrights‚ and writers? Studying Literature can be an eye-opening experience. Reading some great works of World Literature helps us understand things even ourselves. Because by reading we are exposing ourselves to new ideas‚ we begin to have better judgment on things and we benefit from other’s point

EXTRACTION Organic Chemistry Laboratory This experiment was conducted in order to compare single and multiple extraction of caffeine from dried tea leaves and to calculate the percentage yield of caffeine for both extraction procedures. The group was assigned to do the multiple extraction. Before the extraction proper‚ the water bath containing the anhydrous sodium carbonate and distilled water was heated. As the sodium carbonate dissolves‚ tea leaves were added in the mixture and allowed to

The average person is faced with thousands of issues every single day‚ and often they are recognized and handled‚ but other times there are some that are overlooked. Sleep debt‚ an issue that many do not even know exist‚ and yet are plagued by on it an everyday basis. When you skip a night of full rest‚ is it possible to catch up? Most people will simply attempt to return to a normal schedule‚ but yet they cannot shake the feeling of lethargy. This issue is the subject of many studies and investigations

Loggerheads also modify habitats as a result of their foraging activities. The fragments of hard-shelled organisms that loggerheads consume are either discarded or ingested and later deposited with feces at a different location. By reducing the particle size of the shells‚ loggerhead turtles contribute to nutrient recycling in benthic ecosystems by increasing the rate of shell disintegration. Additionally‚ a foraging behavior called infaunal mining has a significant effect on substrate characteristics

In the most simple form‚ FM digital synthesis consists of two sine waves. One is called the modulating wave and the other is called the carrier wave. The carrier wave is the only waveform that is audible. The modulating wave does just as it sounds‚ it modulates the amplitude of the carrier wave‚ and acts as a control value. The frequency of the modulating frequency controls the rate of change in the carrier wave; it controls how fast the modulation occurs in the carrier wave. And the amplitude of

Issue Identification Ford continues to face increased completion from foreign competitors while operating in an industry that is experiencing significant over-capacity. In the face of the challenges presented to us‚ we must determine if Ford should embrace the direct business model which utilizes “virtual integration” that has driven Dell to become a clear leader in their industry. Further‚ if we chose to utilize “virtual integration” based on the Dell model‚ we will need to develop and implement

Experimental Synthesis of Bupropion – A round bottom flask (RBF) containing m-chloropropiophenone (1.0 g‚ 5.9 mmol) dissolved in 5.0 mL dichloromethane (DCM) with 0.25 mL of 1.0 M Br2 in DCM was briefly warmed to initiate the bromination reaction. Afterwards‚ the RBF was placed in and ice-water bath and 1.0 M Br2 in DCM (6.0 mL‚ 6.25 mmol) was added dropwise while stirring. DCM was removed from the reaction by rotary evaporation. Next‚ tert-butylamine (5.0 mL‚ 47.6 mmol) and 5.0 mL of N-methylpyrrolidinone

(Robinson‚ 2011‚ p. 23). The origin of dreams encompasses three areas‚ the psychological‚ the scientific and the theoretical depending on to whom you talk. But for this paper‚ a review of Freud’s concepts of dreams‚ an analysis of the Activation Synthesis Theory of dreams‚ and an inquiry into the Activation-Information-Mode (AIM) Model of dreams will define dream theories. Dreaming is an important aspect of a person’s psychological well-being‚ and Sigmund Freud began the real inquiry into the process

the level of “greenness” of a chemical reaction‚ or its “atom economy”. A higher atom economy is preferable because a greater amount of the reactants will be present in the product as opposed to the byproduct.1 A Suzuki reaction is classified as an organic‚ coupling reaction that includes boronic acid and a halide that are catalyzed by a palladium complex under basic conditions. Other palladium- catalyzed coupling mechanisms include the Heck and Stille reactions. Palladium typically exists in the oxidation
