• The boundary of two mixing regions in the horizontal cross-section was visualized. elongating behavior streakline on experimentally analyzed. fluid transported at a hyperbolic fixed point expands to both regions. A wavy larger Re enhances exchange between rotationally reciprocating impeller separates vessel into under laminar flow regime. In this study, we investigated separation mechanism fr...

Moving Particle Semi-implicit (MPS) which is a meshless and full Lagrangian method is employed to simulate nonlinear hydrodynamic behavior in a wide variety of engineering application including free surface water waves. In the present study, a numerical particle-based model is developed by the authors using MPS method to simulate different wave problems in the coastal waters. In this model flui...

Biology implements intriguing structural design principles that allow for attractive mechanical properties—such as high strength, toughness, and extensibility despite being made of weak and brittle constituents, as observed in biomineralized structures. For example, diatom algae contain nanoporous hierarchical silicified shells, called frustules, which provide mechanical protection from predato...

Background. Palatal rugae pattern of an individual is species specific and is said to be as unique as finger print. Aims and Objectives. The aim of this study was to identify and compare the rugae pattern of Igbo and Ikwerre populations in Nigeria for human identification purposes. Materials and Methods. The present study was conducted from random sampling of University of Port Harcourt student...
