Manivannan Annamalai,J. Jansi Rani,S. Dhanasekar 한국지능시스템학회 2022 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.22 No.2

The aim of the decision-makers in the transportation industry is to maximize profit by minimizing the transportation cost. The transportation structure is the center of economic activity inthe business logistics system. However, transportation costs may vary owing to various unpredictable factors. In this study, cost of the transporting unit is considered as an interval valuedtrapezoidal intuitionistic fuzzy number to deal with these uncertainties. The transportationproblem with interval-valued trapezoidal intuitionistic fuzzy cost is discussed here, and thecosts are ordered by score and score expected functions. As a special case, the interval-valuedtrapezoidal intuitionistic cost is not converted into crisp numbers to solve the transportationproblem and derive the initial basic feasible (IBF) solution through interval-valued intuitionistic costs. Furthermore, the optimality of the derived initial basic feasible solution is checkedusing the modified distribution (MODI) method. The effectiveness and validation of thedeveloped approach were illustrated using numerical examples.

In Situ Growth of Prussian Blue Nanostructures at Reduced Graphene Oxide as a Modified Platinum Electrode for Synergistic Methanol Oxidation

Manivannan, Shanmugam,Kang, Inhak,Kim, Kyuwon American Chemical Society 2016 Langmuir Vol.32 No.7

<P>Herein, we report a facile synthetic strategy for the in situ growth of Prussian blue nanostructures (PB NSs) at the amine-functionalized silicate sol-gel matrix (TPDT)-RGO composite via the electrostatic interaction. Subsequently, Pt nanostructures are electrodeposited onto the preformed ITO/TPDT-RGO-PB electrode to prepare the RGO/PB/Pt catalyst. The significance of the present method is that the PB NSs are in situ grown by interconnecting the RGO layers, leading to 3D cage-like porous nanostructure. The modified electrodes are characterized by FESEM, EDAX, XRD, XPS, and electrochemical techniques. The RGO/PB/Pt catalyst exhibits synergistic electrocatalytic activity and high stability toward methanol oxidation. The porous nature of the TPDT and PB and unique electron-transfer mediating behavior of PB integrated with RGO in the presence of Pt nanostructures facilitated synergistic electrocatalytic activity for methanol oxidation.</P>

<P>Silicon- (Si-) induced salinity stress resistance was demonstrated at physiological and proteomic levels in<I> Capsicum annuum</I> for the first time. Seedlings of<I> C. annuum</I> were hydroponically treated with NaCl (50 mM) with or without Si (1.8 mM) for 15 days. The results illustrated that saline conditions significantly reduced plant growth and biomass and photosynthetic parameters and increased the electrolyte leakage potential, lipid peroxidation, and hydrogen peroxide level. However, supplementation of Si allowed the plants to recover from salinity stress by improving their physiology and photosynthesis. During salinity stress, Si prevented oxidative damage by increasing the activities of antioxidant enzymes. Furthermore, Si supplementation recovered the nutrient imbalance that had occurred during salinity stress. Additionally, proteomic analysis by two-dimensional gel electrophoresis (2DE) followed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) revealed that Si treatment upregulated the accumulation of proteins involved in several metabolic processes, particularly those associated with nucleotide binding and transferase activity. Moreover, Si modulated the expression of vital proteins involved in ubiquitin-mediated nucleosome pathway and carbohydrate metabolism. Overall, the results illustrate that Si application induced resistance against salinity stress in<I> C. annuum</I> by regulating the physiology, antioxidant metabolism, and protein expression.</P>

<P><B>Abstract</B></P> <P>This paper addresses an improved stability criterion for an interval time-delayed neural networks (NNs) including neutral delay and leakage delay. By proposing a suitable Lyapunov–Krasovskii functionals (LKFs) together with the Auxiliary function-based integral inequality (AFBII) and reciprocally convex approach (RCC) approach. The major purpose of this research is put forward to the consideration of inequality techniques together with a suitable LKFs, and mixed with the Leibniz–Newton formula within the structure of linear matrix inequalities (LMIs). It is amazing that, the leakage delay has a disrupting impact on the stability behaviour of such system and they cannot be neglected. Finally, numerical examples have been demonstrated to showing feasibility and applicability of the developed technique. In addition, the developed stability criteria tested for feasibility of the benchmark problem to explore the real-world application in the sense of discrete time-delay and leakage delay as a process variable in the system model.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Some new mathematical technique is adapted together with L-K functionals are estimated its derivative via delay-partitioning approach, which has not been considered yet in stability of model (1) with interval time-varying delays and leakage delays are introduced. </LI> <LI> Different from others in [12,15,16,18,21,22,27,33,44,47], several numerical examples are presented to illustrate the validity of the main results with a real-world simulation.

Sources of silicon influence photosystem and redox homeostasis-related proteins during the axillary shoot multiplication of <i>Dianthus caryophyllus</i>

Manivannan, A.,Soundararajan, P.,Cho, Y. S.,Park, J. E.,Jeong, B. R. Informa UK (TaylorFrancis) 2018 Plant biosystems Vol.152 No.4

<P>The present endeavor has demonstrated the impacts of different sources of silicon (Si) such as potassium silicate (K2SiO3) and calcium silicate (CaSiO3) during the in vitro axillary shoot multiplication of carnation. For the Si treatments, nodal explants were cultured onto the Murashige and Skoog's medium fortified with 1.0mgL(-1) of 6-benzyladenine and 0.5mgL(-1) indole-3-acetic acid with or without K2SiO3 and CaSiO3 in three different concentrations (0, 1.8, or 3.6mM). After six weeks, the shoot induction ratio, number of shoots produced per explant, expression of photosystem (PS) I and II core proteins, and activities of antioxidant enzymes were examined. Among the Si sources, K2SiO3 application enhanced the axillary shoot multiplication and the uptake of Si on comparison with CaSiO3. Both forms of Si resulted in the enhancement of stomatal density, and PS-related protein such as PsaA and PsbA illustrating the apparent involvement of Si on the photosynthetic process. Nevertheless, addition of Si improved the antioxidant capacity during the in vitro shoot multiplication. Overall, the outcomes of the present study suggested that Si can be utilized as a supplementary source during the in vitro propagation of carnation.</P>

Manivannan, Shanmugam,Kang, Inhak,Seo, Yeji,Jin, Hyo-Eon,Lee, Seung-Wuk,Kim, Kyuwon American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.38

<P>We report a virus-incorporated biological template (biotemplate) on electrode surfaces and its use in electrochemical nucleation of metal nanocomposites as an electrocatalytic material for energy applications. The biotemplate was developed with M13 virus (M13) incorporated in a silicate sol gel matrix as a scaffold to nucleate Au-Pt alloy nanostructures by electrodeposition, together with reduced graphene oxide (rGO). The phage when engineered with Y3E peptides could nucleate Au-Pt alloy nanostructures, which ensured adequate packing density, simultaneous stabilization of rGO, and a significantly increased electrochemically active surface area. Investigation of the electrocatalytic activity of the resulting sol-gel composite catalyst toward methanol oxidation in an alkaline medium showed that this: catalyst had mass activity greater than that of the biotemplate containing type M13 and that of monometallic Pt and other Au-Pt nanostructures with different compositions and Supports. M13 in the nanocomposite materials provided a close contact between the Au-Pt alloy nanostructures and rGO. In addition, it facilitated the availability Of an OH--rich environment to the catalyst. As a result, efficient electron transfer and a synergistic catalytic effect of the Au and Pt in the alloy nanostructures toward methanol oxidation were observed. Our nanocomposite synthesis on the novel biotemplate and its application might be useful for developing novel clean and green energygenerating and energy-storage materials.</P>

Manivannan, Abinaya,Soundararajan, Prabhakaran,Park, Yoo Gyeong,Sakkiah, Sugunadevi,Jeong, Byoung Ryong Hindawi Limited 2015 Journal of chemistry Vol.2015 No.-

<P>Aldose reductase (ALR2), a vital enzyme involved in polyol pathway, has befitted as a novel drug target in antidiabetes drug discovery process. In the present study, the binding mode and pharmacokinetic properties of potential polyphenolic compounds with reported aldose reductase inhibitory activity from the genus<I>Scrophularia</I>have been investigated. The human ALR2 enzyme (PDB ID: 2FZD) acted as the receptor in the current study. Among the compounds investigated, acacetin, a methoxy flavonoid, displayed the stable binding to the active site of ALR2 with least binding energy value. Molecular interaction analysis revealed that acacetin interrupts the proton donation mechanism, necessary for the catalytic activity of ALR2, by forming H-bond with Tyr48 (proton donor). In addition, acacetin also possessed favorable ADME properties and complies with Lipinski’s rule of 5 representing the possible drug-like nature compared to other polyphenols. Interestingly, the biological activity predictions also ranked acacetin with higher probability score for aldose reductase inhibition activity. Moreover, the molecular dynamics simulation of ALR2-acacetin complex was validated for the stability of ligand binding and the refined complex was used for generation of receptor-ligand pharmacophore model. Thus, the molecular insights of receptor-ligand interactions gained from the present study can be utilized for the development of novel aldose reductase inhibitors from<I>Scrophularia</I>.</P>

Delamination Characterization of Bonded Interface in Polymer Coated Steel using Surface Based Cohesive Model

Manivannan Ramamurthi,이종신,양승한,김영석 한국정밀공학회 2013 International Journal of Precision Engineering and Vol.14 No.10

The element based cohesive zone model (ECZM) is used widely for examining the delamination or decohesion of the interface surface in adhesively-bonded materials using finite element models (FEM). In this study, a surface based cohesive model available in commercial finite element analysis (FEA) code was used in place of the EZCM because of the similarities with both models when the interface thickness is zero and the advantages of fewer input parameters, easy modeling and reduced computational time. A mode I fracture study with the 90° peel test and simulation were performed in polymer-coated steel. The results were compared with the ECZM. The surface based cohesive model predicted delamination well and the results were closer to those obtained by the ECZM. The cohesive model requires fine meshing in the FEM to predict delamination closely. The same simulations were carried out using coarse meshes to evaluate the feasibility of using it in coarse meshes. The results showed that coarse mesh simulations can also predict delamination with accuracy close to those performed with fine meshes.

<P>Pepper is an economically important horticultural plant that has been widely used for its pungency and spicy taste in worldwide cuisines. Therefore, the domestication of pepper has been carried out since antiquity. Owing to meet the growing demand for pepper with high quality, organoleptic property, nutraceutical contents, and disease tolerance, genomics assisted breeding techniques can be incorporated to develop novel pepper varieties with desired traits. The application of next-generation sequencing (NGS) approaches has reformed the plant breeding technology especially in the area of molecular marker assisted breeding. The availability of genomic information aids in the deeper understanding of several molecular mechanisms behind the vital physiological processes. In addition, the NGS methods facilitate the genome-wide discovery of DNA based markers linked to key genes involved in important biological phenomenon. Among the molecular markers, single nucleotide polymorphism (SNP) indulges various benefits in comparison with other existing DNA based markers. The present review concentrates on the impact of NGS approaches in the discovery of useful SNP markers associated with pungency and disease resistance in pepper. The information provided in the current endeavor can be utilized for the betterment of pepper breeding in future.</P>
