Reserved Domination Number of Line Graph

The reserved dominating set is special up gradation of domination set; where in some of the vertices in the vertex set have special privilege (reserved) to appear in the Dominating set irrespective of their adjacency due to the necessity of the user. The minimum cardinality of a reserved dominating set of G is called the reserved domination number of G and is denoted by R(k) -Y(G) where k is the number of reserved vertices. In this paper reserved domination number of (LPn), (LCn), L(Sn), L(Bm,n), L(Wn) and L(F l,n ) have been found

Retrospective study on role of Coblation in Dennis Kashima for Bilateral Abductor Vocal Cord Paralysis

Vocal cords are very delicate and intricate structure that helps a human being to Breath, Speak as well as to sing. It is a micro structure and their functions are very accurate, even a small change in it by a lesion can produce enormous change in its function (Voice and Singing). Any lesion affecting vocal cord results in change of voice, breathing difficulty. Bilateral abductor palsy is one such condition that can occur due various etiologies which had to be treated appropriately and effectively. There are many techniques available but Dennis kashima is recently evolved technique which is used most commonly now a days because of increased precision, better hemostasis and minimal handling of tissues. 25 patients were selected on the basis of inclusion and exclusion criteria and who had underwent dennis kashima using coblation technique and were studied based on the subjective and objective parameters and statistical analysis were made

Pd(II)-doping studies on tris(thiourea)zinc(II) sulphate crystals: Catalytic effect of Pd(II)-doping on SHG efficiency

Single crystals of Pd(II)-doped tris(thiourea)zinc(II) sulphate (ZTS) have been grown from an aqueous solution by conventional slow evaporation solution growth technique. The characteristic functional groups have been identified by FTIR analysis. Crystal stress has been indicated by powder XRD patterns and FTIR analysis. Incorporation of dopant into the crystalline matrix during crystallization process has been evidenced by energy dispersive X-ray spectroscopy and quantified by inductively coupled plasma technique. The surface morphological changes have been observed in the doped specimen. Mechanical stability of the as-grown specimen has been analyzed by Vickers microhardness analysis. Thermal studies reveal no decomposition up to the melting point. Lattice parameters determined by single crystal XRD analysis reveal only minor variations as a result of low doping. Pd(II) doping has a catalytic effect on the second harmonic generation efficiency improvement of zinc thiourea complex

Analytic Behaviour of Competition among Three Species

We analyse the classical model of competition between three species studied by May and Leonard ({\it SIAM J Appl Math} \textbf{29} (1975) 243-256) with the approaches of singularity analysis and symmetry analysis to identify values of the parameters for which the system is integrable. We observe some striking relations between critical values arising from the approach of dynamical systems and the singularity and symmetry analyses.Comment: 14 pages, to appear in Journal of Nonlinear Mathematical Physic

Mesocorticolimbic monoamine correlates of methamphetamine sensitization and motivation.

Methamphetamine (MA) is a highly addictive psychomotor stimulant, with life-time prevalence rates of abuse ranging from 5-10% world-wide. Yet, a paucity of research exists regarding MA addiction vulnerability/resiliency and neurobiological mediators of the transition to addiction that might occur upon repeated low-dose MA exposure, more characteristic of early drug use. As stimulant-elicited neuroplasticity within dopamine neurons innervating the nucleus accumbens (NAC) and prefrontal cortex (PFC) is theorized as central for addiction-related behavioral anomalies, we used a multi-disciplinary research approach in mice to examine the interactions between sub-toxic MA dosing, motivation for MA and mesocorticolimbic monoamines. Biochemical studies of C57BL/6J (B6) mice revealed short- (1 day), as well as longer-term (21 days), changes in extracellular dopamine, DAT and/or D2 receptors during withdrawal from 10, once daily, 2 mg/kg MA injections. Follow-up biochemical studies conducted in mice selectively bred for high vs. low MA drinking (respectively, MAHDR vs. MALDR mice), provided novel support for anomalies in mesocorticolimbic dopamine as a correlate of genetic vulnerability to high MA intake. Finally, neuropharmacological targeting of NAC dopamine in MA-treated B6 mice demonstrated a bi-directional regulation of MA-induced place-conditioning. These results extend extant literature for MA neurotoxicity by demonstrating that even subchronic exposure to relatively low MA doses are sufficient to elicit relatively long-lasting changes in mesocorticolimbic dopamine and that drug-induced or idiopathic anomalies in mesocorticolimbic dopamine may underpin vulnerability/resiliency to MA addiction

Comparison of Interactive Teaching in Online and Offline Platforms among Dental Undergraduates

In recent years, the educational system has focused more on the holistic development of an individual. Modern technology has changed the educational environment to provide students with better academic opportunities. Along with the education system, teaching techniques and learning tools have also changed with digital evolution. This research was undertaken to assess the academic performance of interactive teaching methods in offline and online platforms in Periodontics among BDS undergraduates at a dental college in India. This prospective study was conducted among 49 students: Group I (n = 24, online class through Zoom) and Group II (n = 25, offline classes). The subject was divided into three modules and was covered in one week. The topics covered, teaching methods, lectures, and activities were similar for both groups. A formative assessment mark was obtained from written tests during the module, whereas the summative assessment mark was recorded from exams conducted towards the end of the module. In the results, a statistically significant difference was not observed in terms of formative assessment between Group I (77.88 ± 12.89) and Group II (77.80 ± 16.09) (p = 0.98). In addition, a statistically significant difference was not observed in terms of summative assessment between Group I (80.54 ± 8.39) and Group II (80.28 ± 11.57) (p = 0.93). Overall, this study suggests that interactive teaching methods in both offline and online platforms in Periodontics showed equivalent performance by the undergraduate dental students

Bifurcations, Chaos, Controlling and Synchronization of Certain Nonlinear Oscillators

In this set of lectures, we review briefly some of the recent developments in the study of the chaotic dynamics of nonlinear oscillators, particularly of damped and driven type. By taking a representative set of examples such as the Duffing, Bonhoeffer-van der Pol and MLC circuit oscillators, we briefly explain the various bifurcations and chaos phenomena associated with these systems. We use numerical and analytical as well as analogue simulation methods to study these systems. Then we point out how controlling of chaotic motions can be effected by algorithmic procedures requiring minimal perturbations. Finally we briefly discuss how synchronization of identically evolving chaotic systems can be achieved and how they can be used in secure communications.Comment: 31 pages (24 figures) LaTeX.

Hydrothermal assisted morphology designed MoS2 material as alternative cathode catalyst for PEM electrolyser application

In this work, we developed a simple and cost-effective hydrothermal route to regulate the formation of molybdenum disulfide (MoS2) in different morphologies, like, nano-sheet, nano-capsule and nano-flake structure by controlling the reaction temperature and sulphur precursor employed. Such a fine tuning of different morphologies yields a leverage to obtain novel shapes with high surface area to employ them as suitable candidates for hydrogen evolution catalysts. Moreover, we report here the first time observation of MoS2 nano-capsule formation via environmentally benign hydrothermal route and characterized them by X-ray diffraction (XRD), nitrogen adsorption and desorption by Brunaer–Emmett–Teller (BET) method, scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) and X-ray photo-electron spectroscopy (XPS) techniques. MoS2 nano-capsules exhibits superior activity towards hydrogen evolution reaction (HER) with a low over-potential of 120 mV (RHE), accompanied by large exchange current density and excellent stability in 0.5 M H2SO4 solution. MoS2 nano-capsule catalyst was coated on solid proton conducting membrane (Nafion) and IrO2 as anode catalyst. The performance of the catalyst was evaluated in MEA mode for 200 h at 2 V without any degradation of electrocatalytic activity
