SUCCINIMIDES: SYNTHESIS, REACTION AND BIOLOGICAL ACTIVITY

This review summarizes the synthetic methods, reactions and biological application of important pharmacological succinimides and summarizes recent developments in their derivatives such as dichlorodiformyl, Schiff base, chalcone, Barbier type allylation etc. Over the last years. The biological activity of the cyclic imides is also briefly discussed. Formation of succinimidyl radicals and Single crystal studies on this type of compounds are beyond the scope of this review and will not be discussed. Nor referenced

Unified Angular Momentum of Dyons

Unified quaternionic angular momentum for the fields of dyons and gravito-dyons has been developed and the commutation relations for dynamical variables are obtained in compact and consistent manner. Demonstrating the quaternion forms of unified fields of dyons (electromagnetic fields) and gravito-dyons (gravito-Heavisidian fields of linear gravity), corresponding quantum equations are reformulated in compact, simpler and manifestly covariant way

Effect of heating or cooling in a suspension of phototactic algae with no-slip boundary conditions

In this study, we investigate the impact of heating or cooling in a suspension experiencing phototactic bioconvection. The suspension is illuminated by collimated irradiation from the top and subjected to heating or cooling from the bottom. The governing equations include the Navier Stokes equations with the Boussinesq approximation, the diffusion equation for motile microorganisms, and the energy equation for temperature. Employing linear perturbation theory, we analyse the linear stability of the suspension. The findings predict that the suspension undergoes destabilization when heated from below and stabilization when cooled from below. This suggests a sensitive dependence of the system's stability on the thermal conditions, providing valuable insights into the behavior of phototactic bioconvection under different heating or cooling scenarios

A Novel Approach for Creating Consistent Trust and Cooperation (CTC) among Mobile Nodes of Ad Hoc Network

The final publication is available at www.springerlink.comThis paper provides a critical analysis of the recent research wok and its impact on the overall performance of a mobile Ad hoc network. In this paper, we clarify some of the misconceptions in the understating of selfishness and miss-behavior of nodes. Moreover, we propose a mathematical model that based on the time division technique to minimize the node misbehavior by avoiding unnecessary elimination of bad nodes. Our proposed approach not only improves the resource sharing but also creates a consistent trust and cooperation (CTC) environment among the mobile nodes. We believe, that the proposed mathematical model not only points out the weaknesses of the recent research work but also approximates the optimal values of the critical parameters such as throughput, transmission over head, channel capacity etc. The simulation results demonstrate the success of the proposed approach that significantly minimizes the malicious nodes and consequently maximizes the overall throughput of the Ad Hoc network than the other well known schemes.http://link.springer.com/chapter/10.1007/978-1-4020-8737-0_9

Modulated structure in the martensite phase of Ni1.8Pt0.2MnGa: a neutron diffraction study

7M orthorhombic modulated structure in the martensite phase of Ni1.8Pt0.2MnGa is reported by powder neutron diffraction study, which indicates that it is likely to exhibit magnetic field induced strain. The change in the unit cell volume is less than 0.5% between the austenite and martensite phases, as expected for a volume conserving martensite transformation. The magnetic structure analysis shows that the magnetic moment in the martensite phase is higher compared to Ni2MnGa, which is in good agreement with magnetization measurement

Some Common Random Fixed Point Results for Expansive Mappings in a Cone Metric Space

The purpose of this work is to extend and generalize some common random fixed point theorems for Expansive type mappings in complete cone metric spaces. We are attempting to generalize the several well- known recent results. Key wards: common fixed point, cone metric space, random variabl
