Abstract

This article explores the effects of two temperatures on the combined problem of wave propagation and thermomechanical loading in a homogeneous isotropic plate. The governing equations are converted to non-dimensional form, and the potential functions are introduced to simplify the problem. The plate's surfaces are assumed to be traction-free, rigidly fixed, thermally insulated and isothermal to study the wave propagation phenomenon. Secular equations in closed form and isolated mathematical conditions for symmetric and skew-symmetric wave mode propagation are derived. The phase velocity and attenuation coefficient are examined for the first problem. The results for uncoupled, coupled, Lord-Shulman (LS) and Green-Lindsay (GL) theories of thermoelasticity have been attained as special cases and agree with that in literature for one temperature theory. In the second part, thermo-mechanical loading has been considered to obtain the expressions of stress and displacement components, conductive and thermodynamic temperatures. The obtained analytical results are computed numerically as well as displayed graphically for copper material to demonstrate the impacts of two temperature theory and compared theoretically as well as numerically with one temperature Lord and Shulman theory.

Abstract

Nowadays, heterocyclic compounds act as a scaffold and are the backbone of medicinal chemistry. Among all of the heterocyclic scaffolds, 1,4-Dihydropyridine (1,4-DHP) is one of the most important heterocyclic rings that possess prominent therapeutic effects in a very versatile manner and plays an important role in synthetic, medicinal, and bioorganic chemistry. The main aim of the study is to review and encompass relevant studies related to 1,4-DHP and excellent therapeutic benefits of its derivatives. An extensive review of Pubmed-Medline, Embase and Lancet's published articles was done to find all relevant studies on the activity of 1,4-DHP and its derivatives. 1,4-DHP is a potent Voltage-Gated Calcium Channel (VGCC) antagonist derivative which acts as an anti-hypertensive, anti- anginal, anti-tumor, anti-inflammatory, anti-tubercular, anti-cancer, anti-hyperplasia, anti-mutagenic, anti-dyslipidemic, and anti-ulcer agent. From the inferences of the study, it can be concluded that the basic nucleus, 1,4-DHP which is a voltage-gated calcium ion channel blocker, acts as a base for its derivatives that possess different important therapeutic effects. There is a need of further research of this basic nucleus as it is a multifunctional moiety, on which addition of different groups can yield a better drug for its other activities such as anti-convulsant, anti-oxidant, anti-mutagenic, and anti-microbial. This review would be significant for further researches in the development of several kinds of drugs by representing successful matrix for the medicinal agents., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)
