The iron metabolism is regulated by Hepcidin, a hormone synthesized in the liver, and the inflammatory condition, present in the uremia, stimulates its production. Hepcidin regulates the absorption of iron in the diet and recycled iron from senescent erythrocytes, exerting its function related to the ferroportin protein found in all cells involved in iron homeostasis. Ferroportin is crucial for cellular iron export and is the only iron efflux mechanism. The expression of ferroportin is…
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…
be described using a common sulfide mineral, Pyrite (FeS2). The oxidation of FeS2 breaks down into three components, iron, sulfate, and hydrogen as seen below: FeS_2+7/2 O_2+H_2 O→Fe^(2+)+2SO_4^(2-)+2H^+ 1/2(1) These three dissolved compounds raise the acidity of the water and decrease the pH, unless neutralized. The ferrous iron, provided enough oxygen, will oxidize to ferric iron, which will reduce the pH level and act as an oxidant to additional pyrite.…
The process of heat-treating Knife River Flint requires a lot of time, preparation, and materials. The Knife River Flint that was used in this experiment came from Mercer County, North Dakota, which there are five different Knife River Flint Quarries in Mercer County. The three closest quarries to where the Knife River Flint in this experiment was collected are the Crowley Quarries, Medicine Butte, and Dodge Quarry. With the help of Russell Redhorn, a Native American monitor I was working…
For the past two decades, more research efforts have been focused on the development of Advanced High Strength Steels (AHSS). The AHSS include Dual Phase (DP) steels, [1–10], High Strength Low Alloy steels (HSLA), Transformation Induced Plasticity (TRIP) steels, Twinning Induced Plasticity (TWIP) steels, and medium manganese steels, (Bouaziz et al., 2013). The majority of the research are focused on the development of third generation of steels due to interest in the mechanical properties of…
given below: • Can be made stronger by alloys and heat treatment. • Easily machined. • Most of them are heavy. • Susceptible to corrosion. Metals can be divided into two; Ferrous and Non-ferrous. Ferrous metals Ferrous metals are those which contain iron and small amount of other elements. Normally, most of them are magnetic. They are more susceptible to rusting when exposed to moist weather conditions. Some ferrous metals are: 1. Mild Steel. 2. Stainless…
Persuasion is a constant and rather successful method of getting people to do certain things. We are constantly being influenced and also influencing other people around us. There are several principles that help explain why humans sometimes irrationally do certain things that they wouldn’t normally do. Three of this several principles include the paradox of choice (which proves that when giving a lot of choice for any particular item, satisfaction decreases and sales decreases), scarcity (which…
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…
In architecture and civil engineering, sustainability plays a main role. All buildings and any construction could be potentially dangerous if they were built or designed in an inappropriate way. All structures and designs have to be safe and stable to prevent the fatal catastrophe of failing construction. The construction of any large objects, such as shopping centers, cathedrals, bridges, and other usually takes a lot of time. There are many forces that affect the designed construction and…
that had come before. Industrialism contributed to the growth of cities and railroads across the nation. One of the most important developments was the revolutionizing of iron and steel. The steel industry emerged around western Pennsylvania and eastern Ohio due to the fact that coal, which is used to fuel the furnaces, and iron, which is made into steel using a variety of methods, were found in abundance in that area. Pittsburg, P.A. became one of the centers of the steel world. New Jersey…
