New method of synthesis of oligoetherols with carbazole ring Renata Lubczak Abstract: The new method of synthesis of multifuntional oligoetherols with carbazole ring suitable for obtaining the polyurethane foams of enhanced thermal resistance was presented. At the first step of the synthesis the carbazole was reacted with excess glycidol to obtain the product of (n +1) functionality, where n is number of equivalents of glycidol reacted with carbazole. Carbazole reacts with glycidol without…

Measurable Outcomes 1. Describe and demonstrate knowledge of modern evolutionary synthesis, natural selection, population genetics, micro and macroevolution, and speciation. I learned about the speciation of animals in Module 3 and in Module 4 I learned about modern evolutionary synthesis, natural selection, population genetics, and mirco and macroevolution. I was able to learn all this information due to the chapter 46 and chapter 47 notes, the online textbook, and the PowerPoint notes. This…

Serotonin (5-HT) is an important neurotransmitter and paracrine signalling molecule in all bilateral animals, where it mediates gut movements and the animal's perceptions of resource availability. 5-HT was found in the gastrointestinal tract (GI tract), blood platelets, and the central nervous system (CNS) [1] [2]. Approximately 90% of 5-HT in the human body is synthesized and released in the GI tract, and the remainder is synthesized in serotonergic neurons of the CNS. 5-HT is synthesized from…

This experiment monitored the synthesis of uridine from the deamination of cytidine through separating the contents of the reaction mixture using HPLC (High-performance liquid chromatography) at various time intervals since the start of the reaction. Cytidine and uridine standards are ran and the output of the HPLC will show two peaks based on the retention times of each compound. Identified the peak with the retention time of 2.422 minutes is cytidine and uridine has a retention time of 2.716…

A novel synthesis method to prepare Si3N4 nanowires from the amorphous silicon nitride (a-Si3N4) powder synthesized by low-temperature vapor-phase reaction method was investigated. Highly crystallized α-Si3N4 nanowires were synthesized from the heat-treatment of a-Si3N4 powder under ammonia atmosphere. The surface of the nanowires was smooth and clean without any attached particles. The thickness of the nanowires was in the range ~200–300 nm with the lengths of tens of micrometers. The…

(2017), to avert the mistake from happening, an enzyme which is DNA polymerase will proofread each nucleotide against its template as soon as it is covalently bonded to the growing strand. Any incorrect pair of nucleotide will be removed and the synthesis will be resumed (Campbell et al., 2015). This action is similar as to the deletion of the wrong letter in the essay and replaces it with the correct one. In many cases, a segment of the DNA strand containing the damage is excised…

Results and Discussion Synthesis of Tin(IV) Porphyrin-Viologen Dyad: Tin(IV)porphyrin-viologen dyads 1 & 2 (scheme 1) used in this study was synthesized by a series of reactions. 1-(4-Carboxybenzyl)-1'-methyl-4,4'-bipyridinium hexaflurophosphate was prepared from the reaction between 1-Methyl-4,4'-bipyridinium iodide with 4-(bromomethyl)benzoic acid followed by ion exchange with NH4PF6. Reaction of 1-(4-Carboxybenzyl)-1'-methyl-4,4'-bipyridinium hexaflurophosphate with [Sn(OH)2TPP] (TPP =…

Reaction Journal Five: Functionalism This week’s reading was over the beginnings of the radical functionalist movement that was lead by Charles Darwin. Darwin was more concerned with how an organism functioned and adapted to change than the perception, sensations, and the structure of consciousness as his fellow psychologists Wundt and Titchener were. Darwin lived a life of privilege and traveled extensively during his lifetime. During his travels, he observed many animal species and made…

Richard Owen “What a strange man to be envious of a naturalist like myself, immeasurably his inferior!” – Charles Darwin 8th May, 1860. Richard Owen was known for many great achievements and awards in his lifetime. Richard Owen was born on July 20, 1804 in Lancaster, England. Owen was educated at Lancaster Grammar School and was apprenticed in 1820 to a group of Lancaster surgeons said by The Editors of Encyclopedia Britannica. Richard Owen was later admitted to the Royal College of Surgeons of…

Charles Darwin and by extension, Alfred Russell Wallace, were heavily inspired by several intellectual influences while collaborating together on ‘Natural Selection.’ Some are more prominent figures, while others are an inspiration by proxy, such as James Hutton. Charles Lyell’s book Principles of Geology. Lyell’s theory that minute changes would gradually increase over long periods of time helped Darwin theorize and coin the term Natural Selection, and with Lyell’s encouragement, he began…
