In this experiment, a series of reactions was performed in order to synthesize 6-ethoxycarbonyl-3,5-diphenyl-2-cyclohexenone, an a,b-unsaturated ketone. The two reactions performed in order to obtain this product were a Michael addition reaction and an Aldol condensation reaction. During this experiment, the reaction solution underwent several changes. Originally, the initial solution was light yellow and transparent. Once heated, the appearance of the reaction solution became bright yellow.…

due to complications. He was then assessed and approved to receive Proton Therapy to target the tumor. After Proton Therapy, he went through a period where no treatment was given due to the side effects of treatment and the disease. A colostomy was later placed due to him having a Perforated Bowel and becoming septic. After nine months of dealing with a colostomy, the client wanted it removed even though he was told that it may not be possible. The surgery was performed to do a colostomy…

Proton pump inhibitors are common clinical drugs that are effective in treating acid-related diseases. They work by reducing the amount of acid produced by gastric glands in the mucous membrane in the stomach. The gastric proton pump resides in this gastric mucosa at the apical pole of the parietal cells. Under normal circumstances, approximately three liters of stomach acid is produced in a day under the regulation of the parasympathetic nervous system. The principle stimulant of acid secretion…

repeated his experiments hopefully looking for a neutral particle. One with the same mass as a proton, but with no charge. James’s experiments were successful; he was able to determine that the mass of the neutral radiation was almost exactly the same as a proton.. He used the equation- to find the neutron (PhysicsLAB: Famous Experiments: The Discovery of the Neutron). James proved Rutherford’s “proton-electrons” pair to be wrong; there was no free electrons in the nucleus. He was then later…

The Proton Pump Inhibitors (PPIs) was introduced to the market in 1989 which advanced the medical treatment of acid-related disorders. Acid-related disorders is used to describe a spectrum of conditions in which acid is involved in the generation of symptoms and / or complications. They are amongst the most usually prescribed agents in inpatient and outpatient settings. It is positioned as the sixth most frequently dispensed therapeutic class in the US and third in Ireland in 2009. As per the…

Since their introduction in 1988, proton pump inhibitors (PPI) have become one of the most prescribed drugs worldwide especially for the treatment of peptic ulcer and gastroesophageal reflux disease (GERD). (1) Proton pump inhibitors (PPIs) effectively suppress gastric acid production by inhibiting the function of H+/K+-ATPase in gastric parietal cells. (2) Also, the indications for esophagogastroduodenoscopy (EGD) have significantly increased, including GERD. These patients usually tend to be…

In Figure 9, the peak at approximately 4.0 ppm is attributed to the protons in ferrocene. Since cyclopentadienyl rings have symmetry and protons that are chemically equivalent, there is only one signal. The rotation of the rings around the iron center yields rapid equilibration of the protons in ferrocene.6 There are no neighboring protons, so the signal is a singlet. The other peak at approximately 2.0 ppm is due to the presence of H2O. This indicates…

all atoms, it is composed of protons, neutrons, and electrons. Protons are positively charged subatomic particles with a relative mass of one. Neutrons are neutrally charged subatomic particles with a relative mass of one as well. The nucleus contains both the protons and the neutrons. Electrons are negatively charged subatomic particles with a relative mass of 1/200. Though protons and neutrally differ drastically in size, their relatives charges are equal. Protons have a charge of +1 and…

organization and can help develop a clear vision of exactly how operations will help achieve them. Proton Holdings Berhad is a Malaysian automobile manufacturer with its headquarter in Selangor. it operates an additional manufacturing plant in Perak. The company was established in 1983 as the sole national car company until the advent of Perodua in 1993. (corporate.proton.com). In this case, Proton is considering expanding its manufacturing operation by purchasing a factory in China. Therefore,…

synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used as a flavouring agent and in perfumes. The diastereomers of the alkene are distinguished through Proton Nuclear Magnetic Resonance (1H NMR) spectroscopy, where the coupling constants of alkenyl protons are different for (E) and (Z) isomers.4 It is often…
