A model of Formula One racing car rotating dry wheel in contact with the ground is studied using a computational approach as a validation case. This validation case focuses on the computed surface pressure around the wheel's center line. This computed result is compared to an experimental one obtained from the available literature work and it showed good agreement. Another case study is considered with replacing the dry wheel model with another wetcondition wheel model. The wet-condition wheel's work is mainly concentrated on the developed aerodynamic forces especially the wheel moment values. This moment is translated to an expression of resistive torque developed by the air stream on the wheel and computed in each case study. In addition, general schematic pictures of the flow behavior around the wet wheel are presented.

In this paper, we examine how the material that makes up the universe connects with the real universe. We look at how man could have been made from clay, just as Genesis tells us. We look at the DNA chemistry and where the components for life came from. We examine what is outside the universe and how it may function as an electric voltaic cell. Energy methods considering Entropy and Enthalpy are applied to the universe. There a brief consideration of the largest stable element. Finally, a calculation is presented on how good and evil coexist in a physical way in the universe.

In this paper we consider some spot calculations on the variables from Astrotheology Physics. Energy, time, space, mass, and distance are used to determine the speed of light accurately. The speed of light is not dependent upon the speed of the observer; rather, it is a constant that is pinned down by the cross product of Energy and time resulting in space and consequent speed of light. Einstein had a degree of freedom that doesn’t exist in our universe.

Heavy metal analysis is the most promising tool to eliminate the unwanted pollution from the atmosphere. Particularly in seawater there are number of heavy metals are present. Assessment of this analysis will be useful to detect the unwanted heavy metals and it is the reason to find the new removal techniques. In surface water of Adirampattinam seashore area the heavy metals, 26Fe, 82Pb, 30Zn, 25Mn, 29Cu, 48Cd, 33As and 23V in water have been detected by Atomic Absorption Spectroscopy (AAS) technique. It is recorded that the analysis of water has been achieved for one year of December 2016 to December 2016 when the water flow is lower and higher respectively. AAS measurements give data collected from 2 stations of Adirmpattinam, Thanjavur District, India, area in equal intervals of three months for four times. Water samples were collected year from December 2016 to December 2016. For each metallic element, AAS analysis technique used a particular wavelength and type of flame. Besides, high and low values of each heavy cation in water are recorded, indicating that the highest value is observed for As (3.250 mg/L) (Station A2) and lowest value is for Cd (0.015 mg/L) in December 2016 (Station A1).

This paper provides some more calculations on the basic Physics of Cusack’s Model of the Universe as presented in the previous paper Astro-Theology. Gravity, Space, Energy, Mass are considered. There is a treatment of Waves and the Speed of Light and Arnold’s ODE’s.

In this paper, we prove fixed point theorems for generalized C-contractive and generalized S-contractive mappings in a bi-complete di-metric space. The relationship between q- spherically complete T0 Ultra-quasi-metric space and bi-complete diametric space is pointed out in proposition 5.1. This work is motivated by Petals and Fvidalis in a T0-ultraquasi- metric space 2000 AMS Subject Classification: 47H17, 74H05, 47H09.
