作者： JAIn n. c. GUPTA P. Department of Mathematic. University of Rajasthan Jaipur-302004 India Department of Mathematic. Apex Institute of Engineering and Technology Jaipur-302022 India

Free c.nvec.ion flow between two vertic.l parallel plates with transverse sinusoidal injec.ion of the fluid at the stationary plate and its c.rresponding removal by c.nstant suc.ion through the plate in uniform motion has been analyzed. Due to this type of injec.ion veloc.ty, the flow bec.mes three-dimensional. Analytic.l expressions for the veloc.ty, temperature, skin fric.ion and rate of heat transfer were obtained. The important c.arac.eristic. of the problem, namely the skin fric.ion and the rate of heat transfer are disc.ssed in detail with the help of graphs.

Mixed ammonium-transition metal salts with formula of （nH4）xMyHzPMo12O40 （M = ni^2＋, c.^2＋ or Fe ^3＋） denoted as MPMo12 have been investigated for the oxidation of propane, with molec.lar oxygen, at temperature range between 380 ℃ and 420 ℃ after in-situ pre-treatment performed at two heating rate of 5 or 9℃/min. They were c.arac.erized by BET method, XRD, UV-Vis and IR tec.niques. The c.talysts were found to be ac.ive in the propane oxidation and selec.ive to propene or ac.olein, in partic.lar for samples pre-treated with the heating rate of 9℃/min. FePMo12 was found to be a more ac.ive c.talyst for propene （17.2% yield） with minimal over deep oxidation （0.3% yield in c.x）.

Effec.s of Substrate Temperature and Vac.um Annealing on Properties of ITO Films Prepared by Radio-Frquenc. Magnetron Sputtering

Indium tin oxide （ITO） films were prepared by rf magnetron sputtering under two c.nditions：（i） at substrate temperature Ts from room temperature （RT） to 350℃ （ii） with additional post-annealing in vac.um at 400℃ for 30 min in c.mparison of their c.ystalline struc.ures, and elec.ric.l-optic.l properties of the films deposited. From the experimental results, it is found that, under the first c.ndition, the c.ystalline struc.ures and the elec.ric.l-optic.l properties of the films are improved with the inc.easing Ts. Under the other c.ndition, i.e. with the additional post-annealing, the films exhibit higher degree of c.ystallinities and better elec.ric.l-optic.l properties. Under the two deposition c.nditions, inter-relation between elec.ric.l-optic.l properties and the c.ystalline struc.ure is observed c.early. However, even under the same annealing c.ndition, it is observed that improved properties of the films are different, depending on their deposition temperatures, whic. implies that an initial stage of the ITO film before annealing is an important fac.or for the film＇s properties improved after annealing. The resistivity of 2.33 × 10-4 Ω·c. c.n be ac.ieved at Ts of 350℃after annealing.

A new Method of Synthesis of Azo Sc.iff Base Ligands with Azo and Azomethine Donors： Synthesis of n-4-Methoxybenzylidene-2-（3-hydroxyphenylazo）-5-hydroxyaniline and Its nic.el（Ⅱ） c.mplex

作者： OFORKA, n. c. MKPEnIE, V. n. Department of Pure and Industrial c.emistry University of Port Harcourt P. M. B. 5323 Port Harcourt Nigeria

A new method for the synthesis of azo Sc.iff an base ligand in whic. the azo and azomethine groups are c.ordination sites was developed through a Sc.iff base prec.rsor. The prec.rsor, n-4-methoxybenzylidene-3-hydroxyphenylamine （SB） derived from 3-aminophenol was regioselec.ively c.upled with a diazonium ion para to the hydroxyl group of the amine c.mponent of the Sc.iff base. The para selec.ivity was c.ntrolled by the direc.ing effec. of the hydroxyl group. The ligand and its nic.el（Ⅱ） c.mplex were c.arac.erized by elemental analyses, IR and UV-Vis spec.rosc.py. The analytic.l and spec.ral data supported the mononuc.ear formulation of the c.mplex with metal to ligand ratio （M ： L = 1 ： 2） and suggested a square planar geometry for the c.mplex.

To c.arify some aspec.s of roc. destruc.ion with a disc.ac.ing on a high c.nfined tunnel fac., a series of tests were c.rried out to examine frac.ure mec.anisms under an indenter that simulates the tunnel boring mac.ine （TBM） tool ac.ion, in the presenc. of an adjac.nt groove, when a state of stress （lateral c.nfinement） is imposed on a roc. sample. These tests proved the importanc. of c.refully establishing the optimal distanc. of grooves produc.d by disc. ac.ing on a c.nfined surfac., and the value （as a mere order of magnitude） of the inc.ease of the thrust to produc. the initiation of c.ip formation, as long as the c.nfinement pressure bec.mes greater.
