    1 A COMPARATIVE STUDY OF KINETICS OF OXIDATION OF PHENETOLE AND Di-n-Butyl ether by ion in acidic medium

    Author: Monika Sharma, P.K. Sharma,(Pages: 159-173)
    Email: N/A          DOI: N/A

    Abstract:

    The Ag (1) catalysed oxidation of phenetole and di-n-butyl ether by ion was found to be first order in and zero order in each substrate. Various energy parameters have been calculated. The salt effect is found to be negative. The rate constant is found to be increased with an increase in the concentration of H2SO4 e.g. - [H+], The reaction was found to be suppressed by allyl acetate, A redical mechanism has been proposed and corresponding rate expression is derived.

    3 Challenges in Research and Higher Education System

    Author: Reshu Chaudhary, Pushpendra and Reena Kumari,(Pages:175-179 )
    Email: N/A          DOI: N/A

    Abstract:

    In the last few decades there had been a thrust on the development of human resource as an important resource. This recourse, besides material resources, contributes substantially to the richness of a nation. In order to exploit this resource there had been a quantum change in the recent past, in the system of education in India. India placed with the advanced countries and the largest exporter of technically trained manpower in the field of software engineering and information technology. Education remained at prime positions in our country since ages. After independence, there was exponential growth in the number of universities, colleges and the student enrollment. However, modern era of science and technology added new dimensions to the meaning of research and education.

    8 FTIR, FT-Raman, and molecular structure investigation of 5-chloro-2,3-dihydroxy-pyridine: A combined experimental and theoretical study

    Author: Vinita, Jayant Teotia, Seema, M.K.Yadav,(Pages: 205-221)
    Email: N/A          DOI: N/A

    Abstract:

    In the present work, the experimental and theoretical vibrational spectra of 5-chloro-2,3-dihydroxy-pyridine(5,2,3-CDHP) were studied. FTIR spectra of (5,2,3-CDHP) in the solid phase was recorded in the region 4000–400 cm-1 . The structural and spectroscopic data of the molecule in the ground state were calculated by using Hartree-Fock and density functional method (B3LYP) with 6-31+G(d,p) basis set. The scaled values have been compared with experimental FTIR . The observed and calculated frequencies are found to be in good agreement. The mulliken charges and van der walls radii for the compound 5,2,3-CDHP is also discussed.

    10 Synthesis, Characterization and Spectral Studies of Noble Heterobinuclear Complexes of Transition Metal Ions and their Biological Activity

    Author: Vinay Phogat, Subash Malik,(Pages: 223-230)
    Email: N/A          DOI: N/A

    Abstract:

    Some noble heterobinuclear complexes of transition metal ions with bis (salicylaldehyde)malonyl-dihydrazone in the presence of 5-nitroindazole Cu(II) / Ni(II)- chloride of the type [ML1 M`L2 Cl2] or [ML1FeL2Cl2]Cl, where M = Ni(II), Cu(II) and M'= Mn(II), Co(II), have been prepared. All the complexes have been characterized by IR, UV vis and EPR spectroscopy, elemental analysis, magnetic moment and molar conductance measurement. Spectral studies and magnetic moment measurement in DMF suggest the covalent nature of the complexes, except the [ML1FeL2Cl2]Cl complex which is 1:1 electrolyte. An octahedral geometry is proposed for M` and square planer for M for the heterobinuclear complexes. The low value of magnetic moment and overlapping EPR signals are due to spin crossover since both of the metals have unpaired electrons with same molecular symmetry. The lowering of the magnetic moment has been discussed. The biological activity (antifungal and antibacterial) of the represented compounds has been studied.

    12 Molecular polarizabilities of tetraphenylporphyrin and their derivatives

    Author: R. P. Semwal and Vivek Rawat,(Pages: 231-237)
    Email: N/A          DOI: N/A

    Abstract:

    Tetraphenylporphyrin, abbreviated TPP or H2TPP, is a synthetic heterocyclic compound that resembles naturally occurring porphyrins. Porphyrins are dyes and cofactors found in hemoglobin and cytochromes and are related to chlorophyll and vitamin B12. The study of naturally occurring porphyrins is complicated by their low symmetry and the presence of polar substituents. Tetraphenylporphyrin is hydrophobic, symmetrically substituted, and easily synthesized. The compound is a dark purple solid that dissolves in nonpolar organic solvents such as chloroform and benzene. The molecular polarizabilities of tetraphenylporphyrin and their derivatives were calculated by using semi-empirical δ – function method and Miller and Savchik’s methods. The results were compared with the molecular polarizability calculated using the Lorentz-Lorentz formula. It is observed that there is a reasonable agreement between the theoretical and the experimental values.

    14 Effect of Time Value of Money on an Inventory System with Partial Backlogging

    Author: Anubha Goyal, S K Soan,(Pages: 239-248)
    Email: N/A          DOI: N/A

    Abstract:

    We discussed an inventory model for decaying items with inflation induced demand over a finite planning horizon. The demand rate is assumed to be a function of inflation; shortages are allowed and completely backlogged. The stock is assumed to undergo deterioration as soon as it is produced. The effect of inflation is also considered. Holding cost is taken as variable. Optimal solution for proposed model is derived by minimizing the total cost. Results have been validated with the help of a numerical example. The whole research caters to put forward some aspects of an inventory model with some real world considerations and market deliberations.

    16 A Study of Axial Viscosity Variation on Non-Newtonian Flow of Blood in an Artery with Mild Stenosis

    Author: Stuti Gupta , Mukesh Gupta ,S.P. Singh ,(Pages: Blood Flow, Blood Viscosity, Power-law fluid, Resistance to flow and Wall shear stress.)
    Email: N/A          DOI: N/A

    Abstract:

    The objective of this present mathematical model is to investigate the axial variation of blood viscosity caused by accumulation of red cells with mild stenosis for the blood flow through an artery using Power-law fluid model. The expressions for dimensionless resistance to flow and wall shear stress have been obtained. Effect of stenosis size and axial variation of viscosity in blood flow is also discussed graphically. All the flow characteristics are found to be affected by the presence of stenosis and axial variation of viscosity of blood. Graphs are obtained by using “MATLAB”.

    Abstract:

    Nanocomposite of copolymer of 3, 4-dimethyl pyrrole and 2, 3-dimethyl aniline doped with HCl was synthesized by chemical oxidative polymerization. APS was used as oxidant. The sample was characterized by FTIR, TGA, XRD and four probe method. FTIR confirms the formation of copolymer and its structure. XRD analysis shows the amorphous nature of polymer nanocomposite. The electrical conductivity of sample was measured by using four probe method. Size and surface morphology was demonstrated by SEM.

    20 EOQ Model for Decaying Items with Power Demand and Partial Backlogging

    Author: S. K. Shon, Tapsaya,(Pages: 269-278)
    Email: sksvishnu@gmail.com          DOI: N/A

    Abstract:

    An inventory model for deteriorating items with time varying demand has been developed. In this model shortages are permitted with partial backlogging. The partial backlogging rate is taken to be proportional to the waiting time for the next replenishment. A numerical example is provided to illustrate the problem and behavior of the total cost function is shown graphically. Sensitivity analysis has been carried out for showing the effect of variation in system parameters.
