Modification of Cubic Equations of State for Polar Compounds
Abstract: Abstract Volumetric properties of substances are crucial thermodynamic parameters in that they aid personnel to compute other thermodynamic parameters like internal energy, enthalpy, entropy, etc. Moreover, these are required in the design of process equipment and in the sizing of pipelines. In 1873 van der Waals proposed an equation to predict volumetric properties of idealized gases. Hitherto, a plethora of such equations known as cubic equations of state have been …

Predicting the Influence of Permeability’s on Settlement of Shallow Foundation
Abstract: Foundation settlement rose as soil permeability increased, excess pore pressure increased with depth, and decreased as shear modulus increased. The expanding soil cycle (shrinkage and expansion) that is principally responsible for foundation settlement is strongly related to water content. The application of modeling and simulation was used to monitor the effect of various soil properties on foundation settlement. But the focus of this study is on Permeability including other soil …

Ferromagnetism in Rare Earth Metal Doped ZnO: A Theoretical Approach
Abstract: The ferromagnetic properties of Diluted Magnetic semiconductor, Zn1−xDyxO is studied from theoretical point of view. The Heisenberg’s and Greens theorem determine the Hamiltonian of the system. The interaction between the nearest neighboring spin is determined by retarded Greens function. By using Greens theory, defect-induced ferromagnetism is discussed. For the ferromagnetic states, the expected exchange integral is positive and negative for the antiferromagnetic states. In addition, from magnetic property, the temperature …

Low-graded coals to upgrade
Abstract: Coal can be defined as a chemically and physically heterogenous, “combustible”, sedimentary rock consisting of both organic and inorganic materials. Organically, coal consists primarily of carbon, hydrogen, and oxygen, with lesser amounts of sulphur and nitrogen. Inorganically, coal consists of a range of ash-forming compounds distributed throughout coal. Major types of analysis are proximate analysis, ultimate analysis and calorific value analysis. Heat value or calorific value determines energy content of …

A Mini Review on Applications and Uses of Alloys
Abstract: Alloys are mixed of metal with other metal or non-metal in the same group that are prepared by mixing of the metals in their molten state through physical processes. An alloy is a mixture of two elements, one of which is a metal. Alloys often have properties that are different to the metals they contain. This makes them more useful than the pure metals alone. For example, alloys are often …
