behavior to improve the health in general. In her article, “Take Your Mark. Get Set. Go. Here 's What You Need to Do to Get Fit,” Katherine Hobson, notes that JoAnn Manson, chief of preventive medicine at Brigham and Women 's Hospital in Boston, says “Physical activity is healthful not only because it fends off excess pounds and builds muscle, thus lowering the risk of heart disease and many other ailments. Exercise also has clear independent effects, among them regulating hormone levels and…
taking the StrengthsFinder test, I knew I had strengths and I knew I had weaknesses, yet I never could pin point exactly what they were. After completing this test, I now have a better understanding of what my current strengths are. Now being in a college setting, I think there are a plethora of opportunities for me to use my strengths to help others grow in their personal life and their relationship with Christ. From this test, I learned my strengths consist of harmony, responsibility,…
nonmetal materials. Chemical vapor deposition can be defined as the deposition of a solid on a heated surface from a chemical reaction in the vapor phase [2]. Chemical vapor deposition belongs to the class of vapor-transfer processes. Differ from physical vapor deposition, CVD process includes chemical reactions. In the process, gaseous material change in to solid which means the process is…
Stainless Steel (Car Components): Stainless steel which is also known as inox steel, is a steel alloy which features 10.5% of chromium. Stainless steel does not rust or stain like normal steel would and even though it is called stainless steel, it is not entirely stainless, because in low-oxygen, high salinity environments it is able to be stained. The main difference between stainless steel and general carbon steel is the amount of chromium present. Due to the amount of chromium that stainless…
4.1 First Side by Side Geometry The first model shown in figure 3 was for twin tunnels already constructed at a centre to centre spacing of 3D. This model helped to identify the influence of construction sequence on surface and subsurface ground displacement upon excavating the first and second tunnels underneath the existing twin tunnels. Figure 3: First Side by Side twin tunnels 4.1.1 Surface Displacements The surface displacements at distances of 4.75m, 7.125m, 9.5m and 11.875m from the…
about 0.5 to 0.75. By using Eq. (2.5), the modulus of elasticity for normal weight concrete having same concrete strength is 22405 MPa. The ratio between the experimental modulus of elasticity of LWC and modulus of elasticity of NWC from (ACI- 318R-05, 2005) equation is 0.77. The suggested equation for Young's modulus of lightweight foam balls concrete in term of its cube compressive strength is as Eq. (4.2): Elwc = 3409 √fcu…
1.1 What is a composite material? Composite materials are materials in which a homogenous matrix is reinforced by a stronger and stiffer constituent that is usually fibrous but may have a particulate or other shape (web.mit.edu). They are produced when two or more materials or phases are used together to give a combination of properties that cannot be attained otherwise. For example steel reinforced concrete, plywood and fibre glass. 1.2 What is a Ceramic Matrix Composite (CMC)? CMCs are a…
2.9 Material Properties 2.9.1 Hardness Test Hardness is defined as a measure of a material’s resistance to contained plastic deformation (e.g., a small dent or scratch). Hardness testing comprises a small indenter being enforced into the surface of the material being confirmed under organized circumstances of load and rate of application. The depth or size of the resulting indentation is measured, which in turn is linked to a hardness number; weaker the material, indentation will be the…
\par Magnesium: As aluminum has been established as a leading role in automotive industry, the use of magnesium in automobile applications is yet limited. Magnesium exhibits a poor formability whereas aluminum has superior formability at room temperature. The main features of ductile magnesium alloys are that they have homogeneous microstructure which is free of brittle inter-metallic particles and having uniform plastic deformation promoted by its grain size as well as its crystallographic…
According to cerakoteguncoatings.com (2017), Cerakote is a Polymer-Ceramic coating that can be applied to metals, plastics, polymers and wood. Cerakote is used on; knives, weapons, tools, some electronic covers, glasses and anything durable that needs a tough coating. This ceramic thin-film coating is intended to offer an appealing finish with unequaled performance. The ceramic coating of Cerakote provides the advantage of having extraordinary; adhesiveness, pliability, corrosion and wear…
