A Note on Waves Generated at a Liquid Solid Interface

In this note, a liquid layer above a thermoelastic halfspace is considered. The frequency equation for the waves generated at the interface is obtained and a few limiting cases are discussed

Waves Generated at the Interface Between an Elastic and a Thermo Elastic Solid

In the present note, we study the conditions for propagation of interface waves when one of the solids is a thermo-elastic halfspace and the other an elastic halfspace. The propagation of plane waves along the interface is studied and the frequency equation is derived. In view of the complicated form of this equation, two limiting cases corresponding to very high or very low frequencies are studied. It is also shown that when the coupling constant in the thermo-elastic solid is put equal to zero, the frequency equation reduces to the equation derived by Stoneley. As another particular case, the frequency equations corresponding to very high or very low wave lengths are obtained

Viscous Liquid Layer Sandwiched Between Two Generalized Thermoelastic Halfspaces

A detailed investigation of waves in a viscous liquid layer of finite thickness sandwiched between two generalized thermoelastic halfspaces reveals the fact that for realistic situations one has to consider the effect of gravity at least in the liquid layer

Kapalabhati (Skull Shining Breath) Pranayama Values

To purify the mind, the oxygen flowing upwards and the gas flowing downwards is to be moved in the opposite direction that is in the abdomen, the transfusion should take place. For this, Kapalabhati helps greatly. Kapalabhati Pranayama is a fast pranayama training method. This exercise reduces the activity of the sympathetic nerves. Hypothalamus function is stimulated. Anxiety, stress, and blood pressure are removed. Positive mood, perception, and tolerance develop. So self-management, decision making, and future planning improve. The Bhagavad Gita states that pranayama is the erasure of sins. The results of scientific research confirm that the Kapalabhati Pranayama values the improvement of physical health, mental health, mental health, and biological health

Worship Traditions and the Influence of Goddesses in Tamil Nadu

In the social tradition of Tamil Nadu, early human beings worshipped nature and the five elements of nature, fire, rain, air, space, and earth. As an extension of this, ancestor worship, also known as worshipping the Dead, has existed in the folk tradition since time immemorial. Continuously divided into Minor Deities and Great Deities, many social groups have been worshipping in order to maintain the social restrictions of their lives. The impact of worship from the Pre-Sangam era to the present, the modulation, the characteristics of goddesses, and its consequences, explain future trends

Note on a Viscoelastic Convection Flow

A mathematical analysis of the free convection flow of an incompressible viscoelastic(Rivlin-Ericksen) fluid from an infinite flat plate under variable suction acted upon by a transverse magnetic field is presented. It is found that the effect of viscoelasticity is to appreciably alter the skin-friction

A Note on waves Generated at a Liquid Solid Interface-II (Viscous Effects)

This paper, being a continuation of a previous note of the same title, deals with the effect of viscosity on the interface waves propagated in a liquid layer overlying a generalized thermoelastic solid halfspace. This note extends the results of Harinath and has applications to defence science and geophysical problems. The problem considered has more relevance to the physical situations encountered in reality than its elastic counterpart. In other words, generalized thermoelasticity fits into the realistic situation better than classical elasticity or coupled thermoelasticity. The details pertaining to the non viscous effects of liquid layer overlying a perfectly elastic halfspace may be found in the treatise by Ewing, Jardetzky and Press those of coupled thermoelasticity in the treatise by Nowacki and details of wave propagation problems in generalized thermoelasticity in the concise paper by Harinath. The stress strain relations used for a viscous fluid may be found in Pipkin, with slight modifications, without any loss in generality. Most of the results obtained here are new

Group 1 and group 2 metal complexes supported by a bidentate bulky iminopyrrolyl ligand: synthesis, structural diversity, and ε-caprolactone polymerization study

We report here a series of alkali and alkaline earth metal complexes, each with a bulky iminopyrrolyl ligand [2-(Ph3CN[double bond, length as m-dash]CH)C4H3NH] (1-H) moiety in their coordination sphere, synthesized using either alkane elimination or silylamine elimination methods or the salt metathesis route. The lithium salt of molecular composition [Li(2-(Ph3CN[double bond, length as m-dash]CH)C4H3N)(THF)2] (2) was prepared using the alkane elimination method, and the silylamine elimination method was used to synthesize the dimeric sodium and tetra-nuclear potassium salts of composition [(2-(Ph3CN[double bond, length as m-dash]CH)C4H3N)Na(THF)]2 (3) and [(2-(Ph3CN[double bond, length as m-dash]CH)C4H3N)K(THF)0.5]4 (4) respectively. The magnesium complex of composition [(THF)2Mg(CH2Ph){2-(Ph3CN[double bond, length as m-dash]CH)C4H3N}] (5) was synthesized through the alkane elimination method, in which [Mg(CH2Ph)2(OEt2)2] was treated with the bulky iminopyrrole ligand 1-H in 1 : 1 molar ratio, whereas the bis(iminopyrrolyl)magnesium complex [(THF)2Mg{2-(Ph3CN[double bond, length as m-dash]CH)C4H3N}2] (6) was isolated using the salt metathesis route. The heavier alkaline earth metal complexes of the general formula {(THF)nM(2-(Ph3CN[double bond, length as m-dash]CH)C4H3N)2} [M = Ca (7), Sr (8), and n = 2; M = Ba (9), n = 3] were prepared in pure form using two synthetic methods: in the first method, the bulky iminopyrrole ligand 1-H was directly treated with the alkaline earth metal precursor [M{N(SiMe3)2}2(THF)n] (where M = Ca, Sr and Ba) in 2 : 1 molar ratio in THF solvent at ambient temperature. The complexes 7–9 were also obtained using the salt metathesis reaction, which involves the treatment of the potassium salt (4) with the corresponding metal diiodides MI2 (M = Ca, Sr and Ba) in 2 : 1 molar ratio in THF solvent. The molecular structures of all the metal complexes (1-H, 2–9) in the solid state were established through single-crystal X-ray diffraction analysis. The complexes 5–9 were tested as catalysts for the ring-opening polymerization of ε-caprolactone. High activity was observed in the heavier alkaline earth metal complexes 7–9, with a very narrow polydispersity index in comparison to that of magnesium complexes 5 and 6

REFINING ELECTRICAL ENERGY SAGS/SWELLS COMPENSATION IN RENEWABLE ENERGIES

The look reason for the traditional UPQC was restricted to raise the power company's distribution grid through getting the chance to supply sag, swell, and harmonic current compensation. Transmission of several distributed forces (DERs) like solar, wind, and plug-in hybrid electric automobiles (PHEVs) for the distribution grid is booming. There's a corresponding rise in power quality problems and intermittencies across the distribution grid. To be capable of reduce the intermittencies and raise the power company's distribution grid, an ultra-capacitor (UCAP) integrated power conditioner is suggested during this paper. UCAP integration provides the power conditioner active power capacity that's helpful in tackling the grid intermittencies plus enhancing the current sag and swell compensation. UCAPs have low energy density, high-power density, and fast charge/discharge rates, that are perfect qualities for meeting high-power low-energy occasions like grid intermittencies, sags/increases. The simulation type of the general technique is developed plus comparison while using the experimental hardware setup. During this paper, UCAP is created-into electricity-link within the power conditioner utilizing a bidirectional electricity-electricity ripping tools that can help in supplying a stiff electricity-link current. The mix could be helpful for offering active/reactive power support, intermittency smoothing, and sag/swell compensation. Design and Charge of both electricity-ac inverters along with the electricity-electricity ripping tools are discussed
