Native American monitor I was working with at the time, we were able to collect a large quantity of Knife River Flint cobbles from an area about eight miles south of Zap, North Dakota. Which is in close vicinity to the Medicine Butte Quarry. (See Fig. 2) One could speculate that the Knife River Flint that was collected could be from the Medicine Butte Quarry. Knife River Flint is the most important component for this…
Test method D= Diameter of ball D=impression diameter F=load HB=Brinell result 2. The Vickers Diamond Test In the Vickers diamond test,the indenter used is a pyramidal shaped diamond, and as in the Brinell test The indenter is forced into the surface of the material under the action of a static load for 10 to 15 seconds.As in the…
and uniformly distributed. The choice of different precipitant in the CuMnOx catalysts leads to the change of the surface distribution of Cu, Mn and O elements, which might be related to the CO oxidation catalytic performance of the catalysts. Table 2: Particle size of CuMnRC catalysts Catalyst Particle size (µm) CuMnRC1 0.675 CuMnRC2 3.127 CuMnRC3 7.435 Thus, the different precipitants used in the preparation of CuMnOx (Cu1Mn8) in the present study considerably affect the particle…
incorrectly labeling the iron content on their products. The purpose of this experiment was to analyze the amount of iron in approximately one serving of Total Whole Grain cereal and in one iron tablet and determine if these accusations were true. The values collected would then be compared to the actual values for these products. Total cereal contains 100% of the recommended daily allowance for iron, and the iron tablet contains 361% of the recommended daily allowance for iron. The actual…
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…
The purpose of this report and lab was to assist in visualizing the structure of infinitesimally small objects and how they fit together. Normal object fit together similarly to microscopic atoms and experiment 2 exploits this to help understand structure property relationships. The knowledge gained here directly applies to the world as applications of the materials becomes apparent as the properties are explored. Copper There are a plethora of modern technological uses of copper. It can be…
their stone and copper predecessors because they could make stronger, longer, and sharper swords. Steel requires large amounts of iron ore, carbon, fast-flowing water, and a long lasting fire. It was created by smelting the iron ore and carbon together in a very hot fire. The Inca didn't have steel because they could not build a long enough lasting fire to heat the iron due to their wet climate. This affected their development because they didn't have strong weapons to take over other…
melting point than non-polar covalent molecules. 1. Mold an aluminum foil boat that will serve as a tray for the table salt, sugar, wax. 2. At different corners of the boat place a very small amount of each substance. a. Table Salt b. Sugar c. Wax 3. Set the hot plate on high. 4. Observe and record the order of melting of the solids in your data table (1, 2, 3) 5. After observations are complete, CAREFULLY remove the aluminum foil boat with crucible tongs and allow it to cool completely.…
oxidized brine carrying copper as a chloride complex, and a reduced fluid that commonly formed in the presence of anaerobic sulfatereducing bacteria. For a sediment-hosted copper deposit to form, four conditions are required: (1) an oxidized source rock, (2) a brine to mobilize copper, (3) a reduced fluid to precipitate copper, and (4) conditions favorable for fluid mixing (Haynes, 1986a, b; Sverjensky, 1989; Ruffell and others, 1997). Sediment-hosted copper deposits are restricted to a narrow…
Ceramics material are compounds between metallic and non-metallic elements where it most frequently oxides, nitrides, and carbides(William D.callister,JR, David G. Rethwisch,2015). This material use for technical applications are commonly based on aluminium oxide. The properties of ceramics which are insulative to the passage of heat and electricity and more resistant to high temperature and harsh environment(William D.callister,JR, David G. Rethwisch,2015). Ceramics in cochlear implants use for…
