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

Table 1. An infrared spectrum for the pure aspirin from the synthesis was taken by using crushed crystals‚ Figure 1. This spectrum was shown with different absorption bands corresponded with the functional groups of aspirin which was observed at frequencies > 1500 cm-1. These infrared frequencies were shown in Table 2. An infrared spectrum of an authentic aspirin was used to distinguish how authentic the infrared spectrum from the synthesis was shown in Figure 2 In this lab‚ aspirin was synthesized

(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

Neuroplasticity is the process where the brain learns to acquire new skills or adapt to different experiences. It is a useful component for the mental capacity of a human being especially during their performances in the day to day lifestyles. This process involves changes in the brain where it includes replacement of injured tissues leading to an addition of neurons in the brain. After that‚ the reorganization of the information processing areas within the brain systems occurs. Whenever a brain

the air we breathe harbor a complex stew of chemicals. Some‚ like oxygen‚ sustain life. Others are pollution stemming from things like car exhaust or from tiny scraps of household products. A pair of new studies adds a level of much-needed detail about exactly how widespread such toxic exposures can be. A new analysis‚ published Wednesday in Environmental Science & Technology‚ reaffirmed that consumer product chemicals including phthalates‚ phenols and flame retardants are ubiquitous components of

The movie Juno is fiction and came out in 2007. It is about Juno MacGuff a 16 year old high schooler who gets pregnant after her first time having intercourse with Paulie Bleeker‚ who is also in high school. Although 9 years old‚ this movie is still extremely relevant in today’s society in regards to teen pregnancy. It tackles all the different options one can take and how emotionally‚ physically‚ and mentally challenge this decision is‚ especially when you’re a teen. Psychologist David Elkind theorized

candidate in the gel. The fragment sizes of the both cut candidates produced on the gel when compared to the DNA ladder were larger‚ at roughly about 6000 base pairs and 6800 base pairs‚ than the predicted size of 2315 and 3119 base pairs. The fragment size of the three control candidates in wells numbered four‚ five‚ and six align with the DNA ladder at about the 6500 base pair mark‚ which better corresponds with the predicted size of 4969 base pairs. This could have been the result of the fragments

Introduction The purpose of this lab is to synthesize Lidocaine from 2‚6-dimethylaniline‚ using diethyl amine‚ 2-chloroacetyl chloride‚ acetic acid‚ and toluene. The Lidocaine was made by adding 2‚6-dimethylaniline to 2-chloroacetyl chloride in acetic acid. Sodium acetate is added in order to make the compound soluble. The product is dried‚ then treated with diethyl amine and toluene. This is refluxed using a water-cooled reflux condenser. The vapor is condensed by the cold water as the compound
