An efficient and greener protocol for the synthesis of poly functionalized pyridines using tetra-n-butyl ammonium fluoride （TBAF） in water is established. Remarkable advantages of the present synthetic strategy over the others are shorter reaction times, higher isolated yields, reuse of catalytic system, simple work-up procedure and more especially its applicability to heteryl and aliphatic aldehydes.

The response surface methodology was employed to study the optimization of microwave-assisted extraction of picroside I and picroside II from Picrorrhiza kurroa Royle rhizomes. The effects of solid to solvent ratio, and extraction temperature, time and solvent on the yields ofpicroside I and picroside II have been investigated using Box-Behnken experimental design. The experimen- tal data were fitted to second-order polynomial equations using multiple regression analysis and analyzed using the appropriate statistical method. By solving the regression equation and analyzing 3-D plots, the optimum extraction conditions were found to be： solid to solvent ratio, 10 ： 90 （w/v）; temperature, 60 ~C; and extraction time, 60 s. Under the optimal conditions, the yields of picroside I and picroside II are 41.23 and 6.12 *** feed respectively, which are in good agreement with the predicted values. The ratio of solid to solvent significantly affects the yields of picroside I and picroside II. Application of microwave- assisted extraction of picroside I and picroside II from P kurroa would dramatically reduce extraction time and solvent consumption.

Smoothed Particle Hydrodynamics (SPH) is fast emerging as a practically usefulcomputational simulation tool for a wide variety of engineering problems. SPH isalso gaining popularity as the back bone for fast and realistic animations in graphicsand video games. The Lagrangian and mesh-free nature of the method facilitates fastand accurate simulation of material deformation, interface capture, etc. Typically,particle-based methods would necessitate particle search and locate algorithms tobe implemented efficiently, as continuous creation of neighbor particle lists is acomputationally expensive step. Hence, it is advantageous to implement SPH, on modernmulti-core platforms with the help of High-Performance Computing (HPC) tools. Inthis work, the computational performance of an SPH algorithm is assessed on multicore Central Processing Unit (CPU) as well as massively parallel General PurposeGraphical Processing Units (GP-GPU). Parallelizing SPH faces several challenges suchas, scalability of the neighbor search process, force calculations, minimizing threaddivergence, achieving coalesced memory access patterns, balancing workload, ensuringoptimum use of computational resources, etc. While addressing some of these challenges,detailed analysis of performance metrics such as speedup, global load efficiency, globalstore efficiency, warp execution efficiency, occupancy, etc. is evaluated. The OpenMP andCompute Unified Device Architecture (CUDA) parallel programming models have beenused for parallel computing on Intel Xeon(R) E5-2630 multi-core CPU and NvIDIAQuadro M4000 and NvIDIA Tesla p100 massively parallel GPU architectures. Standardbenchmark problems from the Computational Fluid Dynamics (CFD) literature are chosen for the validation. The key concern of how to identify a suitable architecturefor mesh-less methods which essentially require heavy workload of neighbor search andevaluation of local force fields from neighbor interactions is addressed.

The present work proposes a novel radially cross-flow multistage solid-liquid circulating fluidized bed （SLCFB）. The SLCFB primarily consists of a single multistage column （having an inner diameter of 100 mm and length of 1.40 m）, which is divided into two sections wherein both the steps of utilization or loading （e.g., adsorption and catalytic reaction） and regeneration of the solid phase can be carried out simulta- neously in continuous mode. The hydrodynamic characteristics were studied using ion exchange resin as the solid phase and water as the fluidizing medium. The loading and flooding states were determined for three particle sizes; i.e,. 0.30, 0,42, and 0.61 ram. The effects of the superficial liquid velocity and solid feed rate on the solid hold-up were investigated under loading and flooding conditions. The solid hold-up increases with an increase in the solid feed rate and decreases with an increase in the superficial liquid velocity. An artificial-intelligence formalism, namely the multilayer perceptron neural network （MLPNN）, was employed for the prediction of the solid hold-up. The input space of MLPNN-based model consists of four parameters, representing operating and system parameters of the proposed SLCFB. The developed MLPNN-based model has excellent prediction accuracy and generalization capability.

ZnSe thin films are successfully deposited by spray pyrolysis deposition technique. Deposited thin films are characterized by X-ray diffraction study, and it reveals that spray-deposited ZnSe thin films are polycrystalline with hexagonal crystal structure. Surface morphology is carried out by scanning electron microscopy. It shows cotton-like morphology, and optical properties, such as absorbance, transmittance, reflectance, band gap, refrac- tive index, extinction coefficient are studied. Photoluminescence shows strong emission at 497 nm. Also, spray- deposited ZnSe thin films are hydrophilic in nature, which is shown by contact angle meter.
