Fabrication and Parametric Analysis of Thermal Sensing Dielectric PZT Thick Film Nano Ceramic Device Developed by SOL GEL Technique
Abstract: AbstractExtensive investigation carried out during earlier half of twentieth century, prominently established that the ionic radius of an atom gets reduced to significant levels with decrease in coordination number. The findings of Goldsmith and Pauling showed that ionic radii contracts by 4, 6 and 12% when coordination number is reduced from 12 to 8, 6 and 4 respectively. It is obvious that coordination number reduction takes place at the surface …

Analysis of Flow around Conical, Ogive Nose Cones in Hypersonic Space Shuttle
Abstract: Hypersonic flow is a high Mach number regime used to distinguish flow fields, phenomena and problems appearing at flight speed far greater than the speed of sound. In high speed flows shock waves are formed during the flow. High speed flow have high energy level, thus dissipate large amount of heat, resulting in high temperatures, which may even burn the surface. The nose cone should be built with an outer …

Experimental Demonstration on Polymer based Microfluidics at the First Quantisation in Physics
Abstract: Difference between classical mechanics and quantum mechanics is the first quantisation in physics as the quantum theory is first quantisation in physics. Quantum field theory is the second quantisation in physics. Principles of fluid mechanics belong to the classical mechanics (non-quantum). Hence, fluid mechanics is present at the first quantisation in physics. Bulk-fluidics, microfluidics and nanofluidics are the levels of fluid mechanics from the aspects of miniaturisation. In this experimental …

Flavonoids Regulate Airway MUC5AC Mucin Expression through Modulation of Multiple Signalling Pathways
Abstract: Airway mucus is a component of pulmonary innate immune function and plays very important role in defense against invading pathogenic microbes, chemicals and particles. The protective function of airway mucus is attributed to the viscoelasticity of mucins. Mucins are large glycoproteins play important role in cell–cell adhesion, airways protection, Nuclear-factor kappa B signalling, epidermal growth factor receptor signalling. Eleven mucin genes (among twenty identified mucin genes) have been expressed at …
