Nernst equation

We, the students of Professor Bart Goddard’s Differential Equations class (M 427J), are writing to you about a recent incident for which he is at risk of losing his position in the university. During the 12:00 PM class on Wednesday, February 22, 2017, Professor Goddard told a cautionary tale about how, in the Holocaust, Nazi engineers used lime to prevent blood from ruining the train tracks of the trains carrying the Jews to the camps, calling on the engineering students in the audience to…

In the short story “The Cold Equations” by Tom Godwin the main point was to never do something that you shouldn't be doing because it can end in a very different way than you intended it to. In the short story “The Cold Equations” by Tom Godwin the main character gets on a spacecraft although she is not supposed to. When she does this she gives herself up and comes out and tells the guy why she came on the ship. The main reason she came on the ship was to see her brother because she hadn't seen…

The cold equation written by Tom Godwin’s is a science fiction story that highlights the story of a girl named Marilyn who wanted to visit her brother Gerry in Woden since she has not seen him in years. She did that by hiding in the stowaway on the ship who has an EDS cruiser named Thomas Barton that is getting to Woden to transfer the medicine serums. Although in 1989 “The cold equation” was transformed into an episode of a twilight zone, which was made to create even more of a suspension story…

Supply chains that are complex are commonly modeled as linear programs (LPs). They can effectively trade off broad range of criteria. To model FMCG supply chains accurately, one must include discrete aspects of decision making, which requires solving a mixed-integer program (MIP). It has become significantly important for managers, given the widespread use of linear models today, to be able to develop good, efficient models to aid them in the decision-making process. Three important factors;…

Title: Application of Self-Organization Neural Network Technique (SOM) to Optimize Finite- Element Partial Differential Equation (PDEs) Results in Square-Shaped Structures Analysis. The finite-element method (FEM) is a computationally method for solving partial differential equations (PDEs) with specific boundary conditions over a domain. When we applying the FEM to a domain, it has to divide to a finite number of elements and nodes. The collections of the elements and nodes form the…

Business Math was first put into practice by industry leaders, George Dantzig and Harold Kuhn, in the 1950’s. Business Mathematics is important in everyday life because not only does it help companies and organizations record and manage business related operations but it is also helpful for companies and organizations to make data driven decisions that ultimately relate to logistics, supply chains and warehousing. Business math differs from other types of math’s because it consists of more…

If R and r is the Circumradius and Inradius of a non-degenerate triangle then due to Euler we have an Inequality stated as and the equality holds when the triangle is equilateral. This ubiquitous inequality occurs in the literature in many different equivalent forms [4] and also Many other different simple approaches for proving this inequality are known. (some of them can be found in [2], [3], [5], [17], and [18] ). In this article we present a proof for this Inequality based on two basic…

If muscle membrane potentials vary as a function of ionic composition of the extracellular solution, changes in [K+]o should alter VM values. Moreover, EK, given by the Nernst equation, should accurately predict changing VM values. As extracellular potassium concentration is systematically increased, membrane voltage should be rendered more positive (less negative). Indeed, if [K+]i is 140 mM (according to Bernstein’s model), extracellular [K+] much smaller than 140 mM (e.g., 5.4 mM, 10 mM)…

Exploring Electrochemistry Aim: The Aim of this experiment is to investigate electrochemistry including spontaneity, conductivity, galvanic cells and lead-acid cells. Spontaneous reactions will be explored by observing the two reactions below: Zn(s) + Cu2+(aq) →Zn2+(aq) + Cu(s) Zn2+(aq) + Cu(s) → Zn(s) + Cu2+(aq) Conductivity will be explored through measuring the conductivity of water and water with salts. A galvanic cell will be constructed to investigate the two halves of a redox…

In this experiment, various electrochemical cells were measured and calculated to determine their electrical cell potential. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (0.10 M) │ Cu(s), E cell potential was determined to be 1.040 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Zn (s) │Zn2+ (0.10 M) ││ Cu2+ (1.0 M) │ Cu(s) E cell potential was determined to be 1.060 V while the standard E˚ cell potential was 1.10 V. In the electrochemical cell Cu (s)…
