Freezing and crystallization are linked in that both processes involve initial nucleation followed by crystallization. Sonication is thought to enhance both the nucleation rate and rate of crystal growth in a saturated or supercooled medium by producing a large number of nucleation sites in the medium throughout the ultrasonic exposure. Two main theories which explained the mechanism of nucleation are Hickling theory and molecular segregation theory. Among two theories Hickling is most commonly…
correlation between the two subjects to be viewed easier. Trend lines help people accurately determine future outcomes that can come in handy if there is a problem. This is possible because trend lines make it easier to find the slope intercept equation. This equation could be used to find future points in the graph. In this essay I will try to determine who is the best basketball player between Lebron James and Michael Jordan by using a trend line.
Before finding the better player, we first…
The writing process is both complex and interesting at the same time. There are many ways to write and the process is different for everyone. In this essay, I will explain my found writing process and analyze my process alongside Peter Elbow’s Teaching Thinking by Teaching Writing, Alvarez’s Writing Matters, and Stafford’s A Way of Writing.
My first step in writing begins with choosing the right location. Usually I choose my office or bedroom, but sometimes when I stick to a routine, I become…
to come in contact or find proof? This lack of contact is sometimes referred to as “The Great Silence.” Many have tried to come up with solutions to this paradox and some of them definitely seem plausible. One of the obvious ones is that the Drake Equation is completely wrong. However, one of the bigger theories out there is known as “The Great…
3.2 Effects of particle size
The particle size of the catalyst was highly influenced on the reaction rate, when the particle size of the catalyst was decreased, therefore their surface areas was increased and the ratio of catalyst surface and reactant volume was playing a crucial role for controlling the reaction kinetics. The reaction was takes place on the surface of a substance, increasing the surface area should increases the quantity of the substance that is available to react, and will…
4.2 Resources CO2
Fig.1 depicts the principle of chemical energy transmission system.
Fig.2 explain the Eva-Adam process.
5. Thermodynamics of CO2 reforming of methane
It is essential to understand the thermodynamic of CDRM represents as follow:
CH_4+CO_2 □(→) 2CO+〖2H〗_2 ∆H_298=247 KJ⁄(mol ) (1)
This reaction above is highly endothermic which is favored by low pressure but, requires a higher temperature. A reverse…
investors will not pay for risk premiums, and defined by following stochastic differential equations:
Where: S(t) represents the price process of an underlying assets. V(t) is the variance of the corresponding instantaneous returns. And the initial condition S(0), V(0) should be strictly positive. r is the risk-free return rate (non-negative…
188.8.131.52 Interpretation of Regression Model
The above equation can be written as
D ∝ P^0.058/(V^(-0.117) 〖D_b〗^(-0.133) )
By observing the above equation we can say that the LAZ Depth is directly proportional to the Laser Power and inversely proportional to the Scan Velocity and Beam diameter. The observations of the model can be summarized as below:
As Laser Power increases the LAZ Depth of workpiece surface will also increase. This is because the heat input to the workpiece is increasing…

4.1 Material removal rate
The material removed from each coupon was determined by measuring its mass before and after electro-polishing. Theoretical values were then obtained using Faraday’s laws of electrolysis as shown in Equation 9.
Where m is the mass of material removed in grams, I is the current and t is the electro-polishing time. EW is the equivalent weight which depends on the chemical composition of…
