Corrosion Cracking Stress Corrosion Cracking (SCC) is the growth of cracks with a under the combined effects of a static stress and a specific chemical environment. All SCC failures involve a macroscopic brittle performance, and the ductility of the material is reduced. It is universally acknowledged that there is no single mechanism for stress corrosion cracking (Ford, 1984). Stress corrosion spectrum (Parkins, 1972) demonstrates the significant alloy-environment the mechanism…

Felicity, Is it subjective or objective? Do people strive to attain happiness by means of their own understanding of the world? Can it be compared to reality, where we try to base our view of what is real and true as much as we are capable of through own perhaps incomplete reasoning? Likewise for happiness do we all devote our time to obtain that happiness as closely as possible, according to our own understanding or is it all just subjective? Have your heard of a cliché statements such as ‘Mind…

equipped with armament. I cannot figure out why the Customs and Border Patrol chose to use the MQ-9 Reaper instead of its predecessor the MQ-1 Predator. The only viable option I can come up with is the fact that the Reaper comes equipped with the Synthetic Aperture Radar and the Predator does not, which could be of vital importance along the border while searching for drug smugglers and illegal immigrants. Another variant, the Guardian, was adopted and used by Customs and Border Patrol along…

of Venus was mapped in 1991 by the Magellan expedition, which revealed evidence of extensive volcanic activity on the planet--yet the timing of this volcanic activity remains a mystery. About 80 percent of Venus' surface is covered in volcanic material. Most of the volcanoes are believed to be inactive, yet there is some evidence to suggest more "recently" activity ("recent" in this context meaning within the last 500 million years). There are no lava nor caldera (craters created by volcanic…

1985; Taylor and Eggleton, 2001), it also acts as a hindrance to exploration for mineral deposits under cover (Anand, 2016; Salama et al., 2016) and geological mapping in general. The term regolith refers to all of the weathered and/or unconsolidated material from basement rock to earth surface including interbedded fresh rocks (Taylor and Eggleton, 2001). Tardy (1997) estimates that nearly one third of the area of all continents is covered by regolith resulting from lateritic weathering. Except…

Terrazzo, composites, and concrete are all materials that can be used in the interior of a space. In this paper, I am going to explain the similarities and differences between concrete and terrazzo, what each material is composed of, how these materials are used, and the different subcategories of each material. I’m also going to discuss how each material can be altered, in terms of the look and feel of it. Composite flooring is composed of aggregate and a binder, also known as the matrix. The…

Analysis of “Knowing What You Believe” by Quassim Cassam Introduction: In the article “Knowing What You Believe” by Quassim Cassam talks about how the transparency account doesn’t support epistemically immediate. He defends the views about that the belief of P is epistemically inferential and therefore not immediate, which he bases it the transparency. Cassam starts by defining the notion of transparency and gives three questions in which he plans to answer. Then he continues on to talk about…

where he became certified with the Texas Commission on Fire Protection. He said that at 20 years old he liked the work schedule of a firefighter. From there, his career grew. Hallmark is now an instructor, fire investigator, firefighter, hazardous materials technician and EMT for the San Antonio Fire Department in San Antonio, Texas. Loving his job and making his family happy simultaneously can sometimes be difficult. “I know it’s hard on my family with me being gone a lot and in dangerous…

Electronic materials is very useful in today 's world, they can be used almost in all field. There are a lot of electronic materials produced every day, like semiconductor, Piezoelectric and ferroelectric materials, magnetic material etc. This lab is more concentrate on the electronic resistivity with the changing of annealing time. And XRD can help people figure out the grain size of the sample, and find the rule of the electronic resistivity with the changing of annealing time. Introduction…

in contact, and the normal force helps calculate kinetic friction. Static friction is the force which must be overcoming to originally start moving an object. Once the frictions are calculated, coefficients may be calculated as well. Equipment & Materials: -Spring Scale -Several Wooden Blocks (Around 3” x 12” x 3/4”) -Yarn or String -Push Pins or Thumb Tacks -Table or Desk Surface Procedure: For the first part of the procedure, a loop of yarn was attached to the end of a 12” block by using a…
