The determination of Iron content in Ferritin practical. Introduction: Ferritin is a protein in the body and it acts as a storage to the Iron, in non-toxic way. Iron un-bound to ferritin forms a complex is call Apoferritin. Unbound to iron the protein complex ferritin is known as Apoferritin. Within this complex the agent that releases the Iron is Ferrozine²¯. Iron(Fe(II)) Iron bonds to the Ferrozine to create the purple ferritin complex. It has a very unique structure which forms a spherical shell
Hormones are not the only things that affect someone’s mood, the food we eat and what nutrients or vitamins they contain can also determine how one feels. Just like how certain foods are healthier than others, some help mood more than others. There are many ingredients that can determine a good or bad mood and they can be found in many people’s kitchens because they are commonly used. Some ingredients that help improve mood are protein, dopamine, and resveratrol. Protein stabilizes blood sugar and
Plastics are one of the most used materials on a volume basis in U.S. industrial and commercial use. Plastics are commonly into today’s lifestyle and make a major contribution to virtually all product areas. Although the plastics industry in the United States is now in its second century, the most important developments have occurred since 1910. The roots of these modern developments go back not only to the research of cellulose nitrate by John Wesley Hyatt in the 1860s, but also to the plastic-like
The ABC’s of Meteorite Collecting By Vincent S. Foster As Colby Navarro sat at his computer on March 26, 2003, he had no idea that a meteorite was about to come crashing through the roof of his Park Forest, Illinois, home, strike his printer, bounce off the wall, and land near a filing cabinet. The rock, about four inches wide, was part of a meteorite shower that swept through the Chicago area, damaging at least six houses and three cars. Scientists said that before the rock broke apart, it was probably
My Senior project is welding and welding is a manufacture or sculptural process that joins materials, most often metals or thermoplastics, by causing fusion, which is joined from lower moderation of heat metal fusion techniques such as brass and soldering, which do not fuse the base metal. In addition to melting the base bullion, a filler material is typically added to the joined to form a pile of molten material that cools to form a joint that is ordinarily stronger than the degraded material.
Marbles Introduction to Marbles Stone is a naturally occurring combination of minerals found in the outer solid layer of the earth. Stone is classified into three main categories: Igneous Metamorphic Sedimentary Stone plays important role in construction industry because of its tough, durable characteristics. Stone products used in industry as building material and in many other applications are majorly natural stone products and artificial stone products. Marble and granite are two
Gold has been discovered on every continent on earth. Gold is a yellow precious metal, the chemical element of atomic number 79, valued especially for use in jewelry and decoration, and to guarantee the value currencies. Gold is malleable and shiny, making it a good metalworking material. Also, gold is considered to be a transition metal. Transition metals are unique because they can bond with others elements using not just their outermost shell of electrons (the negatively charged particles that
Brass is a metal composed mainly of the two elements zinc and copper. With copper being the main element, brass is generally considered a copper alloy. The color of the brass will vary from a dark reddish brown to a lighter silver-yellow color depending on the amount of zinc present. When copper appears on the lighter end of the color scale, it means it has a high concentration of zinc. Brass is a popular choice for it is stronger than copper but not quite as strong as steel. It is easily malleable
Comparison of Engineering Properties between Pure Copper Slag Brick and Spent Copper Slag Brick Salmaliza Salleh and Rishanthi.T Abstract- This paper was carried out to compare the engineering properties between pure copper slag brick and spent copper slag brick. Pure copper slag is the waste product of copper ore smelting and refining process while spent copper slag is the waste product from the process of abrasive blasting of metal surfaces. It is widely used in ship building, ship repair, other
Principles of Heat Treating of Steels Principles of Heat Treating of Steels A steel is usually defined as an alloy of iron and carbon with the content between a few hundreds of a percent up to about 2 wt%. Other alloying elements can amount in total to about 5 wt% in low-alloy steels and higher in more highly alloyed steels such as tool steels and stainless steels. Steels can exhibit a wide variety of properties depending on composition as well as the phases and microconstituents present, which
make the strongest electromagnet possible. Apparatus: · Iron Rod · Leads · Power Pack · Crocodile Clips · Insulated Wire · Iron Nails · Voltmeter · Plastic Beakers · Electronic Balance Hypothesis: I expect the strongest electromagnet to have a 'soft' iron core; the highest number of coils (45); the strongest voltage (10V) and current and have the coils evenly spread across the iron rod. The 'soft' iron core means it changes easily between being magnetised and
Reasons Behind the Industrial Revolution The Industrial Revolution was the widespread replacement of labor by machines driven by water wheels, windmills and later by steam power. This change called the Industrial Revolution was a process, which began in the 18th century and continued well into the 19th century. The Industrial Revolution was the result of interrelated changes, which transformed agricultural economies into industrial ones. The immediate changes made by the Industrial Revolution
for granted, not appreciated of what engineers have done to manufacture this product and what thought and pressure the engineers had to undergo to produce such a simple product. Kettles have been used ever since the ancient romans times, made from iron or a ceramic material. The first electrical kettles that used heating elements were introduced in 1891 by the Carpenter Electric Company of Chicago. The Ceramic kettle became widely used during world war two as metal used for the kettle was in short
Manganese is a naturally occurring mineral comprising approximately 0.1 % of the earth’s crust. It is found in many salts and mineral complexes that are widely distributed in rocks, soils and on the floors of lakes and oceans. For aquatic systems the manganous (Mn2+) and manganic (Mn4+) oxidation states of manganese are the most significant. The element dissolves in the water of some underground aquifers when it is present in the geological layers within the aquifer. As a result, since groundwater

Brass is a generic term for alloys that contain copper and zinc (Lab Packet). An alloy is a metal that consists of a mixture of metals. They can have varying amounts of zinc and other elements composed within the alloy such as iron, lead, aluminum, and tin (Lab Packet). These variations in the components of brass produce a wide range of brass properties but all brass is corrosion resistant. This ideal alloy has many purposes ranging from musical instruments to architectural purposes such as pipes
As the name of this group of abrasive operations suggests, their objective is to achieve superior surface finish up to mirror-like finishing and very close dimensional precision. The finishing operations are assigned as the last operations in the single part production cycle usually after the conventional or abrasive machining operations, but also after net shape processes such as powder metallurgy, cold flashless forging, etc. The finishing processes discussed in this section include honing, lapping
can be generally represented as (MeO.6Fe2O3), where Me is divalent metal such as Sr, Ba, and Pb or a mixture of these [12]. Barium hexaferrites (BaFe12O19) with a magnetoplumbite structure are well known as hard magnetic materials which are based on iron oxides. Hexagonal ferrites are referred to as hard because the direction of magnetization cannot be changed easily to another axis [].Barium ferrite possesses relatively high Curie temperature, coercive force and magnetic anisotropy field, as well

is large and rounded with a flat face. These headed can be weighted on each side of the head to help direct the ball when you hit it. Depending on how the weights are set, they can help fix a slice or a hook problem. Another type of head is the iron head. This is an angled piece of metal that is used to direct the ball higher in the air along with great distance. The high the degree of angle is the higher the ball will go in the air, but it won't travel as far distance wise. The last type of
