Human iron metabolism

In this experiment, I tested the effect of saltwater on the formation of rust on an iron nail. To test this, The first step was to fill each labeled cup with the correct ratio of salt to water. The ratios varied between groups which created different concentrations of salt for the different groups thereby constructing different levels of my independent variable. The next step was to record the initial mass of each nail and then place them in the cups. Then, the nails were left to soak in their…

“From the dawn of mankind, metals have fascinated man in many ways. From simple items found in the fire to advances in forming metals into trinkets, jewels, to weapons.” (A History of Welding). Welding is a profession that has been around since the dawn of the use of metals. The art of welding has changed the way we make things, and how we are able to build massive structures that stand taller than mountains. Well, this art form is called welding, and I believe it would suit me very well as a…

One of the challenges chemical engineers face with ethane cracking in a tubular reactor is the formation of a detrimental coke layer on the inner tube wall. According to the article [1], the mechanism is mainly induced by degradation of hydrocarbons to an aromatic structure by condensation and dehydrogenation. This brings about a bunch of various effects described in the article. In my model built during the term project, I decided to introduce a new effect of reducing the diameter, consider…

know what you will need to get started. You will need shampoo, a rubber band or a hair clip, a plastic bag or a hairdryer, a heat protectant conditioner, a silk scarf, a wide tooth comb, a blow dryer (optional), a light grease (optional), and flat irons. The conditioner does not have to be heat protected but you run the risk of causing split ends or burning your hair. Now that you have all the materials you will need you can start the process to straightening your hair. The first thing you need…

rust is seen every day and affects one 's life every day. This is due to the fact that “Iron doesn’t hold onto its electrons very tightly, says Scully, making it the perfect anode for an electrochemical reaction to take place” (Brownlee 2). Skully is a corrosion expert at the university of Virginia (Brownlee 1-2). When metal rusts, the metal atoms lose their electrons to oxygen, which forms a bond between the iron and oxygen creating the compound that is seen in the form of rust (Brownlee…

Metal plays a key role in development and it is the backbone for the manufacturing industry. For years, various metal have been extracted from the mineral ore found in nature, but with the time high grade ore have is getting depleted and the option at left with us is to processing low grade ore which makes recovery process expensive. In such scenario recycling metals seems a lucrative option as it helps environment by reducing the amount of scrap or waste material getting disposed into…

Human activities such as burning fossil fuels, the use of synthetic nitrogen fertilizers, and the launch of the nitrogen in the wastewater has changed dramatically from the global nitrogen cycle. The Nitrogen & Phosphorus Cycle Video Describes the desperate…

Due to regulations in the past, Farnsworth Paper Works, Inc., has an increasing buildup of fly ash on our property that has not been properly disposed. We would like to propose solutions to the Department of Natural Resources to allow us to receive permits to convert about half of our fly ash into low-grade fertilizer and to dispose of the rest of the unusable fly ash into the landfill on our property. Introduction Background Farnsworth Paper Works, Inc., which is regulated by the Department of…

Hardness Testing Lab 1 Moriah Ausherman E882U679 Kunza Arifa ME-251-10959 Thursday 3:30 Experiment Date- 8/31/2017 Due Date- 9/7/2017 Introduction: The purpose of this lab is to ascertain the hardness of two different materials. One material is aluminum the other will be determined through testing. Hardness is defined as a material’s ability to resist plastic deformation by indentation. Harder objects are more likely to resist deformation. The results of a hardness test will be…

is an iron-containing protein in red blood cells that enable the red blood cell to bind oxygen in the lung and transport the oxygen to tissues and organs throughout the body. Oxygen binds reversibly to these iron atoms and is carried throughout the blood. As part of the experiment, we computed the concentration of hemoglobin and iron in a crystalline blood sample by measuring the absorbance of the sample as methemoglobin and cynamethemoglobin at 450-650nm. Furthermore, the hemoglobin and iron…
