Chem 51LB Report Ngoc Tran - Student ID # 72048507 The purpose of this lab is to examine the composition of three components of gas products of elimination reaction under acidic condition by conducting the dehydration of primary and secondary alcohol, and under basic condition by conducting the base-induced dehydrobromination of 1-bromobutane and 2-bromobutane. Then gas chromatography is used to analyze the composition of the product mixtures. Gas chromatography (mobile phase) is used to analyze the composition of three components of the gas products. A syringe needle with gas product is injected into the machine, and the component is eluted and the composition is related to the column or the peaks.
Vitamin B12 (Cobalmin) is a water soluble vitamin and plays a key role in the normal functioning of the brain and nervous system, and in the formation of red blood cells. Vitamin B12 deficiency can occur if the body does not absorb enough vitamin B12 from the gastrointestinal tract or when there is not enough dietary intake of the vitamin. One common cause of deficiency is as a result of pernicious anaemia which is an autoimmune disorder that results in inflammation and damage to the stomach lining, and loss of parietal cells. The parietal cells produce intrinsic factor, a protein needed for absorption of Vitamin B12 in the gut.
What is the normal fate of bilirubin, and what role does the liver play? Explain how Mrs. Fender’s cirrhosis is related to her jaundice. • Bilirubin is a product of the heme of hemoglobin formed during the breakdown of erythrocytes. The liver removes the bilirubin from the blood and excretes it into the intestines as bile. When the liver is damaged, bilirubin, which is a yellow pigment, spills over into tissues and the blood, thus giving the skin a yellowish coloring.
Billy Bibbit, 31, of Oregon, passed away December 4, 1958 as a result of injuries sustained in a suicidal attempt. He was born December 5, 1927 in Portland, the son of Mary and Paul Bibbit. He attended Beverly Cleary School and graduated from Grant High School in 1945, where he was awarded with the gold academic award. He was emitted into a Mental Hospital, by choice, in 1950. Billy was a shy but a proud man, many that knew him describe him as nice, hard trying, and beautiful.
Before the sun is up, a woman is scrambling around her house, searching for a clean dress to wear. It has not rained the last few days, so she has had to cut her shower to only three minutes and hasn’t been able to do the laundry that has started to pile up. The woman finds the proper outfit — a blue, floor-length dress and a white bonnet that she ties under her chin. She peeks out of her bedroom window, the first burst of sunlight now streaking across the black water.

Jami Bull Mr. Mollenger Forensics Science 23 February 2018 Power of Proof The Innocence Project is a non-profit legal organization that helps people prove their innocence when wrongfully convicted through new DNA testing. 70% of eyewitnesses misidentified and 45% involved misapplication of forensic science.

The biuret solution is a blue solution made up of sodium hydroxide and copper (II) sulfate which turns pink or violet in the presence of proteins, peptides and compounds containing 2 or more peptide linkage. A spectrophotometer measures the respective amounts of light consisting of different wavelengths absorbed and transmitted by a pigment solution. Spectrophotometer works when white light is separated into lights of different wavelengths by a prism which different colors of light passes through the sample. The transmitted light strikes a photoelectric tube, converting light energy to electric current that is measured by a galvanometer. The transmittance reading measures the absorbance of reactants and determine the concentrations of protein

He finally was able to run away to Canada and became a free man.
ONE SNOWY NIGHT last winter, I walked into a pizzeria in Morrisville, Pennsylvania, with my right pant leg hiked up my shin. A pager-size black box was strapped to my sockless ankle, and another, somewhat larger unit dangled in a holster on my belt. Together, the two items make up a tracking device called the BI ExacuTrack AT: the former is designed to be tamper-resistant, and the latter broadcasts the wearer’s location to a monitoring company via GPS. The device is commonly associated with paroled sex offenders, who wear it so authorities can keep an eye on their movements. Thus my experiment: an online guide had specified that the restaurant I was visiting was a “family” joint.
The doors of Bishop Bernward were commissioned by the Bishop St. Bernward around 1015 and feature sixteen different panels. Eight are from the Old Testament, and eight are from the New Testament. The doors are decorated with panels with representations of the Creation of Eve, the Presentation of Eve to Adam, the Temptation, the Fall, the Expulsion, the Labours of Adam and Eve, the Sacrifice of Abel and Cain, the Murder of Abel, the Annunciation, the Nativity, the Adoration of the Magi, the Presentation to Simeon, Christ before Pilate, the Crucifixion, the Maries at the Sepulchre, and Christ appearing to St. Mary Magdalen. The events from Genesis leading up to and portraying the Fall of Man proceed in a downward direction, those which depict man's redemption through Christ progress in an upward fashion. The doors were
Bix Beiderbecke’s musical career was a very lived lasting only seven years. He died Aug. 6, 1931, as the result of alcohol-related pneumonia at age 28. The official cause of death was lobar pneumonia and edema of the brain. Before the '30s were over, Beiderbecke's life is said to have served as an inspiration for the Dorothy Baker novel "Young Man With a Horn”. In 1950, the novel eventually became a film featuring Kirk Douglas.
Up Above My Head: The Musical Legacy of Bernice Johnson Reagon History 3020 Dr. Bynum Ryan Dooley October 28, 2015 Congressman John Lewis said of the importance of music in the movement for racial equality, “The civil rights movement without its music would have been like a bird without its wings…” Music is an integral part of social development. Songs can bolster a cause or movement, catalyzing action, or subduing conflict. Music is one the most important tools in communication, allowing compound ideas and views to be centralized with a simple melody or verse through composition. Bernice Johnson Reagon and members of SNCC (The Student Nonviolence Coordinating Committee) developed an invaluable tool in the fight for racial
