polyphenol oxidase (Faisal. S et.al, 2013) which influence in the oxidative activity when the potatoes are cut causing it to become brown in color (Vitti M.C et. al, 2011). Potatoes are not encouraged to be sun-dried as the slow process of removal of water will induce the growth of fungal on the food's surface (Faisal. S et.al, 2013). Blanching treatments or osmotic dehydration method where the highly perishable foods such as fruits and vegetables or in this case, potato, are immersed in the…
Paragraph 1 Compare and contrast the crystal structures and crystal chemistry of quartz, α-FePO4 and β-FePO4. Haines’ research paper studies the change that occurs in the FePO4 structure as it is studied from temperatures 294K to 1073K. A transition is noticed at 980K, when it’s tetrahedral α-quartz structure experiences high pressure levels, changing the structure to β-phase, a more dense octahedral structure. Cell parameters of FePO4 in α-phase increases in cell parameters and volume as…
Two chromatographic methods were developed for the assay of the FDA approved lozenges containing dextromethorphan hydrobromide (DXT) and menthol (MNT). The first was a green HPTLC method which depends on using Merck HPTLC aluminum sheets of silica gel 60 F254 and methanol-ammonia (10:0.1, v/v) as mobile phase. This was followed by densitometric measurements of the spots which were retained at 0.28 ± 0.01 for DXT and 0.76 ± 0.02 for MNT scanned at 210 nm. The method was found linear over the…
method was never disscused with the team members so sometimes the potatoes were wrapped in a towel and lightly squeezed, and other times they were rolled on the towel. The two methods of drying are very different: one is more rough and takes more water out of the potato, while the other method uses wet parts of the towel to dry the potatos. To eliminate this inconsistency, all the lab members should agree to one method of drying, specifically a method that is the most gentle (such as rolling…
Water was moving down on the edge of the bath. Steam was surrounding the girl sitting in the water, hiding her from the real world that was behind the window, and letting her dream. Water splash - and her thin legs merged to each other, transforming into azure, scaly mermaid tale. The steam became thicker, and then purple whales and giant pink elephant flew above her head. The noise around transformed into the songs of sirens that lured her to join the dream, leaving any troubles behind. Knock…
“Gretchen, come up and see the moon.” She didn’t answer, but a child’s voice startled me. “Help!” A young girl was clearly visible in our wake. I yelled louder for my wife and she hurried up the companionway, “What, Alec?” “There’s a girl in the water.” Gretchen grabbed the spotlight, “How far away?” “Three…
Introduction: Leaf Disk float in water alone. When a solution consisting of a small amount of sodium bicarbonate is added to the water it causes the leaf disk to sink. As photosynthesis continues in the leaf disk it releases oxygen and causes the leaf disk to rise. While cellular respiration is occurring also the rate that the disk raise is an in implicit measurement of the net rate of photosynthesis. The independent variable in this lab is the solution and the light because it can be…
Brian Robeson is an intellectual person. He had dramatic and traumatizing experiences in the wilderness. He gained intelligence, courage, and confidence during these experiences. He learned information that an average person wouldn’t know. He knows what to do in a time of trouble. He is not afraid to do the right thing. He knowns that plans are going to work out. Brian is a very intelligent person. When Brian and Derek first arrived Brian knew it was going to rain in six and a half hours just…

For example, most residents had to use the sluggish murky water of the dam except for the wealthier people which could order water from certain companies. London was unsanitary because people didn’t have baths only in the wealthiest of homes they often thought they were bad. The same goes for toilets people would basically use chamber pots and…
