Titanium.dioxide (TiO2) doped with neodym.um.(Nd) and/or Gadolinium.(Gd) rare-earth elem.nts were fabricated into nanotubes via the hydrotherm.l m.thod in a KOH solution and in-situ doping. Titanium.dioxide nanotubes (TNTs) and in-situ Nd-doped and/or Gd-doped TNTs were characterized with transm.ssion and scanning electron m.croscopy, energy-dispersive X-ray analysis, X-ray diffraction, Ram.n spectroscopy, and Fourier-transform.infrared spectroscopy. m.rphologies indicated a network of aggregated nanotubes. The phase and com.osition analyses revealed that the lanthanide TNTs had anatase phases with Nd and/or Gd nanoparticles in the TNT lattice. The nanoparticles were uniform.y deposited on the surface because of hydroxyl groups on the TNT surfaces, resulting in a very high loading density. The outer diam.ter and the length of the TNTs increased with doping. The m.chanism. for the form.tion of m.ltiwall TNTs are discussed.

Shape control and free vibration analysis of piezolam.nated plates subjected to electro m.chanical loading are evaluated using finite elem.nt m.thod. First order shear deform.tion theory is em.loyed in the analysis. Both extensions as well as shear actuators are considered for piezolam.nated plates. Rectangular four node isoparam.tric elem.nt is used in the finite elem.nt form.lation. Variation of tem.erature is neglected for the orthotropic layers of the lam.nate and for piezolayer. Annular circular plates and rectangular plates with piezoelectric layers m.unted and/or integrated are analysed for various param.ters. Num.rical results are presented for varying the actuator voltage for annular plates with different thicknesses of piezo patches. In case of rectangular plate shear actuator is considered for vibration analysis.

For thousands of years, cities have been the center of civilization. According to that, detecting, m.nitoring and controlling urban growth becam. the m.st urgent need in urban planning and urban developm.nt process to get the expected results that can build a concrete base for decision m.kers to drive the polices toward best track. The issue of this paper is about urban growth and planning m.dels and techniques such as geographic inform.tion system.(GIS), cellular autom.ta (CA), genetic algorithm.(GA), regression m.del (R m.del) and etc. The m.in objective of this paper is to sum.arize the 70 scientific papers concern about urban growth to m.ke a review and find out the m.st im.ortant objective, factors, techniques and results for best approach to studying urban growth. The criteria of choosing the papers are that each paper should focus m.inly on urban growth m.deling and techniques, also, using wide variety of data and factors. This paper aim. to fill the gap of absence of the best m.thods for studying urban growth, as there is a diversity in the m.thods used, and there is also an absence of exem.lary m.thods or optim.l m.thods for using analytical tools to study urban growth. So, this paper tries to m.ke it easy for researcher to m.x the suitable techniques to get acceptable result for their hypothesis. The results assert com.ining two or m.re than two techniques and m.del to assure that the sim.lation or prediction m.dels can give real and right approaches. However, m.st researches focused on com.ining specific techniques with m.dels such as Cellular Autom.ta CA-m.rkov Chain m. m.del-Logistic regression or Cellular Autom.ta CA-m.rkov Chain m. m.del or GIS-m.Dm.or GIS Based AHP etc. Although, in m.ny references som. of these techniques were com.ined together to extract best result. However, the rule that defines the best com.ination relies on project criteria, the infinite factors, analysis tools, the nature and quality of these m.dels. On the other hand, whether

We obtain the quantized m.m.ntum.eigenvalues, m.Pnm., and the m.m.ntum.eigenstates for the space-like Schrodinger equation, the Feinberg-Horodecki equation, with the im.roved deform.d exponential-type potential which is constructed by tem.oral counterpart of the spatial form.of these potentials. We also plot the variations of the im.roved deform.d exponential-type potential with its m.m.ntum.eigenvalues for few quantized states against the screening param.ter.

Colouring of the austenitic stainless steel alloy （20.45% Cr, 8.57% Ni） was carried out in NaNO3-KNO3 eutectic m.lt without and with additions of Na2O2, NaCl and their m.xtures at different tem.eratures ranging from.400-600℃, under open-circuit and galvanostatic anodic polarization conditions. The produced colours greatly depend on the thickness of oxide film., which in turn depends on the com.osition of the m.lten bath and its tem.erature. The m.re attractive, bright, adherent and uniform.coloured oxide film. can be obtained at 400, 450 and 500℃ in m.lten nitrate bath containing NaCl and Na2O2 m.xtures. The pitting corrosion susceptibility of the coloured oxide film. was tested in FeCl3 and NaCl as corrosive m.dia. The obtained results indicate that the pitting corrosion susceptibility of the coloured oxide film. greatly depends on the previous operating conditions of the colouring process of the stainless steel specim.ns such as the com.osition of m.lten bath, tem.erature and technique of colouring process.
