In this study, a volume based hygroscopicity (kv) model was applied to the data obtained from Optical Properties of Aerosol and Clouds (OPAC), the properties obtained were the radii of arctic, continental clean, continental polluted, maritime clean, maritime polluted, Sahara and urban at eight relative humidity of 0%, 50%, 70%, 80%, 90%, 95%, 98%, and 99%. The Kelvin radii (A) and bulk hygroscopicity (B) were determined using regression analysis, the result shows that B is more dominant than A for maritime clean and maritime polluted, also discovered that maritime clean and maritime polluted has higher value of kv while Saharan has lowest. We also discovered that R2 is greater than 90%, p-value and significance are less than 0.05, therefore the parameter kv is good for atmospheric modeling.

Ferrous Selenide (FeSe) thin films were prepared onto glass substrate by Electron beam evaporation technique. X-Ray Diffractometer analyses showed that highly c-axis oriented and high-quality films were obtained on various annealing temperatures of 100°C, 200°C and 300°C respectively. From Scanning Electron Microscopy and its Elemental analysis of all the films showed low-temperature structural phase transition at different annealing temperatures of RT, 100°C, 200°C and 300°C respectively. The optical studies of FeSe thin film on glass was found most different from all the others, and its bandgap decreases from 2.85 eV to 2.75 eV for different annealing temperatures of the thin films. Optical analysis is demonstrated that Ferrous (Fe) and Selenide (Se) are homogeneously distributed in the film. Atomic Force Microscopy (AFM) and its 2D and 3D analyses were found that microstructure of FeSe thin films.

Here is the Structural Analysis of a bridge design that models the physical universe parameters found in Astrotheology.

Here is a paper that uses the theory of electromagnetism to model gravity and the universe. The standard magnetic flux, capacitance, conductivity, dielectrics are considered. The mathematics includes the golden mean parabola, Euler’s Identity, Matrices, Eigenvectors, and Differential equations

This article presents two simple and analog situations related to classic mental experience known as “Einstein’s Train”, which explains the temporal dilatation regarding special relativity theory, and then it points a logical contradiction between them.

The solution of problem of non-homogeneous partial differential equations was discussed using the joined Fourier- Laplace transform methods in finding the Green’s function of heat equation in different situations.

In this brief paper, I reduce the irrational physical constants it terms of energy. I show mathematically, how the constants terminate in the mass of a proton. The energy balance terminates the irrational numbers; especially important is the golden mean.
