Scientific Study of Amish Tripathi\u27s Novels
No full textAmish Tripathi is a rising contempory writer. His passion towards Indian mythology inspired him to write about Hindu Mythology upon Hindu God and Goddesses. He is one of the best selling author in English literature, written about mythological stories. All the novels of Amish Tripathi are modernized in such a way that it can match with the interest of today\u27s generation. His novels are about society, women, oppressed classed etc. Apart from these his novels are full in scientific techniques. There are so many scientific concepts in the novel \u27Shiva Triology\u27. There are three parts in Shiva triology. The first part is the immortals of Melutra, the second part is the secret of the Nagas and the third part is the oath of vayuputras. The concept like Radiowaves, manufacture of somras, Divizian of cell etc. are scientifically explained in the novel Shiva triology
Novel Approach of Fractional Calculus in Physiological Flow through Curved Vessels
No full text<p>The present investigation explores peristaltic transport of a generalized fractional Maxwell rheological fluid with occlusion in a two-dimensional curved channel based on long wavelength and low Reynolds number approximations. An analytical approximate solution of the fractional differential equation is obtained by using a Modified Fractional Decomposition Method (MFDM) having integral w.r.t (d). The expressions of stream function, volumetric flow rate and pressure gradient are obtained. The effects of the fractional parameters, the curvature of the channel, viscoelastic material constant and peristaltic occlusion on pressure difference and the friction force across one wavelength are illustrated graphically and interpreted in detail. Exceptional accuracy is achieved with MFDM which holds significant potential for multi-physical biofluid dynamics simulations. The computations have shown that the pressure ow relationship is an inverse linear one. Increasing curvature parameter markedly reduces the pumping rate. Increasing fractional parameters both enhance the gradient of the pumping curve. An elevation in occlusion parameter enhances the pressure. Increasing occlusion and fractional parameters induce the opposite effect on friction force to those on pressure. The present analysis is relevant to intestinal transport phenomena and also in the design of biomimetic smart micro-pumps deployed in colonoscopy.</p>Vamsi Krishna Narla. Dharmendra Tripathi.

Peristaltic transport of fractional Maxwell fluids in uniform tubes: Applications in endoscopy
No full textAbstractThis paper presents the effect of endoscope on peristaltic transport of fractional Maxwell fluids through the gap between two concentric uniform tubes under the assumptions of large wavelength and low Reynolds number. The inner tube is an endoscope and the outer tube has a sinusoidal wave traveling down its wall, i.e. the inner tube is rigid and outer tube is flexible. Solutions for the problem are obtained by two numerical methods named as homotopy perturbation method and variational iteration method. The impacts of endoscope, relaxation time and fractional parameters on pressure per wavelength and friction force (on inner and outer tubes) per wavelength are discussed with the help of computational results which are presented in graphical form. On the basis of the present study, it is revealed that pressure diminishes with increase in the magnitude of first fractional parameter, ratio of tube radii and relaxation time whereas it enhances with increasing the magnitude of second fractional parameter and amplitude ratio. The study further reveals the important fact that the effects of all pertinent parameters (except ratio of tube radii) on friction force at inner tube are similar in magnitude but opposite in direction to that of pressure and the effects of same parameters on friction force at outer tube are similar in magnitude but opposite in direction to that of pressure

PERISTALTIC FLOW OF COUPLE-STRESS CONDUCTING FLUIDS THROUGH A POROUS CHANNEL: APPLICATIONS TO BLOOD FLOW IN THE MICRO-CIRCULATORY SYSTEM
No full text The present investigation is devoted to study a theoretical investigation of the peristaltic flow of a couple-stress conducting fluids in a porous channel under the influence of slip boundary condition. This study is applicable to the physiological flow of blood in the micro-circulatory system, by taking account of the particle size effect. The expressions for axial velocity, pressure gradient, stream function, frictional force and mechanical efficiency are obtained under the small Reynolds number and the large wavelength approximations. Effects of different physical parameters reflecting permeability parameter, couple-stress parameter, Hartmann number as well as amplitude ratio on pumping characteristics, frictional force, mechanical efficiency and trapping of peristaltic flow pattern are studied. The computational and numerical results are presented in graphical form. On the basis of our discussion, it is concluded that pressure reduces by increasing the magnitude of couple-stress parameter, permeability parameter, slip parameter, whereas it enhances by increasing the magnitude of magnetic field and amplitude ratio. </jats:p

No full text A numerical study is presented to examine the peristaltic transport of fractional bio-fluids (viscoelastic fluids with fractional Oldroyd-B model) through the channel. Analysis is carried out under the assumptions of long wavelength and low Reynolds number. Numerical and analytical approximate solutions of problem are obtained by using homotopy analysis method. It is assumed that the cross section of the channel varies sinusoidally along the length of channel. The effects of fractional parameters, material constants (relaxation time and retardation time), time and amplitude on the pressure and frictional force across one wavelength are studied with particular emphasis. The computational results are presented in graphical form. It is found that the effect of both fractional parameters on pressure is opposite to each other i.e., pressure reduces with increasing magnitude of the first fractional parameter whereas it increases with increasing magnitude of the second fractional parameter. The effects of relaxation time and retardation time on pressure are similar to that of first and second fractional parameters, respectively. </jats:p
