Two-dimensional interactions due to moving load in generalized thermoelastic solid with diffusion

引用

Applied Mathematics and Mechanics(English Edition) 2008年第2期29卷 207-221页

作者： sunita Deswal Suman Choudhary Department of Mathematics Guru Jambheshwar University of Science and Technology Hisar 125001HaryanaINDIA Department of Mathematics Govt.CollegeNalwa (Hisar) 125037HaryanaINDIA

The present paper is concerned with the investigation of disturbances in＇a homogeneous, isotropic elastic medium with generalized thermoelastic diffusion, when a moving source is acting along one of the co-ordinate axis on the boundary of the medium. Eigen value approach is applied to study the disturbance in Laplace-Fourier transform domain for a two dimensional problem. The analytical expressions for displacement components, stresses, temperature field, concentration and chemical potential are obtained in the physical domain by using a numerical technique for the inversion of Laplace transform based on Fourier expansion techniques. These expressions are calculated numerically for a copper like material and depicted graphically. As special cases, the results in generalized thermoelastic and elastic media are obtained. Effect of presence of diffusion is analyzed theoretically and numerically.

Reduced Order Modeling & Controller Design for Mass Transfer in a Grain Storage System

引用

International Journal of Automation and computing 2014年第4期11卷 399-403页

作者： Paramita Guha sunita Mishra Agrionics Division Central Scientific Instruments Organisation

This paper considers the problem of simulating the humidity distributions of a grain storage system. The distributions are described by partial differential equations(PDE). It is quite difficult to obtain the humidity profiles from the PDE model. Hence, a discretization method is applied to obtain an equivalent ordinary differential equation model. However, after applying the discretization technique, the cost of solving the system increases as the size increases to a few thousands. It may be noted that after discretization,the degree of freedom of the system remain the same while the order increases. The large dynamic model is reduced using a proper orthogonal decomposition based technique and an equivalent model but of much reduced size is obtained. A controller based on optimal control theory is designed to obtain an input such that the output humidity reaches a desired profile and also its stability is *** results are presented to show the validity of the reduced model and possible further extensions are identified.

Astible Rivularis: Bioactive Compounds and Pharmacological Functions

引用

Chinese Journal of Integrative Medicine 2019年第10期25卷 795-799页

作者： sunita Timalsena Prem Prasad Lamichhane Department of Pharmacology Faculty of Medicine Siriraj Hospital Mahidol University Bangkok (10700) Thailand Department of Microbiology Faculty of Medicine Siriraj Hospital Mahidol University Bangkok (10700) Thailand

Astilbe rivularis Buch. Ham., a rhizomatous perennial herb of the Saxifragaceae family, has been listed in rare species. In traditional medicine the plant has been used for the treatment of ulcer, bleeding during child birth, inflammation, body ache, diarrhea, and dysentery. This article reviews and analyses the traditional use, pharmacological activities of the corresponding bioactive compounds, and toxicological data on A. rivularis species. A. rivularis has been used across Indian subcontinent to treat various human ailments. Its extract consists of alkaloids, flavonoids, coumarins and glycosides. These extracts as well as isolated bioactive compounds demonstrated various biological activities including antimicrobial, anti-peptic ulcer, anti-inflammatory, and antioxidant activity. Toxicological studies of the extract on brine shrimp larvae demonstrated mild toxicity;however no acute toxicity in mice. Although the pharmacological effect of A. rivularis has been poorly explored, the available data validated its use in ethnomedicine. To reveal the cryptic therapeutic potential of the species, research should focus on identification and mechanistic studies of the bioactive compounds.

Modeling and targeting an essential metabolic pathway of Plasmodium falciparum in apicoplast using Petri nets

引用

Applied Mathematics(A Journal of Chinese Universities) 2022年第1期37卷 91-110页

作者： Sakshi Gupta Gajendra Pratap Singh sunita Kumawat Department of Mathematics Amity School of Applied SciencesAmity University HaryanaGurugramIndia School of Computational and Integrative Sciences and Concurrent Faculty at Special Centre for Systems Medicine Jawaharlal Nehru UniversityNew DelhiIndia

Petri net(PN) is one of the promising computational and mathematical formalisms used to represent and study the behavior of complex metabolic networks. The various available analysis techniques of PN could be used to validate and analyze the network in different scenarios. Plasmodium falciparum is one of the threatening parasites which causes malaria, a deadly disease affecting a large number of today’s world population. The development of antimalarial drug resistance is an emerging global threat, highlighting the need to discover novel antimalarial targets. The fatty acid biosynthesis of malarial parasite is one of the essential metabolic pathways required for its growth and is present in apicoplast, a non-photosynthetic plastid. The malarial parasite obtains fatty acids by using type two fatty acid synthase(FAS II) enzyme,which is different from type one enzyme used by human host, making it an ideal drug *** article proposes and studies the PN model of the parasite’s FAS II pathway to analyze the mechanism of potential drug targets in this pathway. The proposed PN model can serve as a base for further findings in the field of antimalarial drug targets to decrease the malaria mortality rate.

Displacement Field due to Nonuniform Slip along a Long Dip-Slip Fault in Two Welded Half-Spaces

引用

Journal of Earth Science 2012年第6期23卷 864-872页

作者： sunita Rani Neeru Bala Ram Chander Verma Department of Mathematics Guru Jambheshwar University of Science and TechnologyHisar 125001India

The solution of static deformation of two homogeneous, isotropic, and perfectly elastic half-spaces in welded contact due to a long dip-slip fault with uniform slip is well known. The aim of the present article is to obtain the static deformation of two homogeneous, isotropic, and perfectly elastic half-spaces in welded contact due to nonuniform slip along a long dip-slip fault. The fault is vertical and lies entirely in the lower half-space, extending up to the interface. Four slip profiles are considered： lin- ear, parabolic, elliptic, and cubic. Closed-form expressions for the elastic residual field have been ob- tained for the different slip profiles. The displacement field due to four nonuniform slip profiles is com- pared with the displacement field due to uniform slip. For comparison, we have assumed the source potency for different slip profiles to be the same, which is achieved by taking the fault slip at the inter- face constant and varying the fault width. It is found that the displacement field varies significantly at the fault width rather than at the interface. Moreover, uniform slip along the fault makes the edges singular. This singularity at the lower edge is not present in the case of nonuniform slip along a long dip-slip fault.
