In this paper, we present the exact solution of the one-dim.nsional Schrrdinger equation for the q-deform.d quantum.potentials via the Nikiforov-Uvarov m.thod. The eigenvalues and eigenfunctions of these potentials are obtained via this m.thod. The energy equations and the corresponding wave functions for som. special cases of these potentials are briefly discussed. The PT-sym.etry and Herm.ticity for these potentials are also discussed.

Double prim.ry m.lignancies could be divided into two categories, depending on the interval between tum.r diagnoses. A secondary m.lignancy could be defined as a new cancer that has occurred as a result of previous treatm.nt with radiation or chem.therapy. Second prim.ry m.lignancy can occur at any age but it’s com.only at old age. A 46 prem.nopausal fem.le patient presented to our outpatient clinic com.laining from.a m.ss in her right breast, routine m.tastatic work-up for distant m.tastasis declared m.ltiple hepatic m.tastases, RT renal m.ss, and bone m.tastases. Palliative radiotherapy to tender and weight bearing sites followed by 4 cycles of system.c chem.therapy FEC regim.n were received. Tru-cut needle biopsy from.renal m.ss detected renal cell carcinom. of clear cell type, the patient started sunitinib and tam.xifen with bisphosphonate (Zoledronic acid), assessm.nt of the response revealed reduction of the size and num.er of HFLs, and the size of renal m.ss, so the patient was decided to do cytoreductive nephrectom. and then continued on TAm.and sunitinib. Collectively, due to the rising incidence of m.ltiple prim.ry m.lignancies, further studies should be done not only for better clinical evaluation and treatm.nts but also for accurate determ.nation of possible causes, pathogenesis, effective m.nagem.nts and screening program..

A series of new m.xed ligand com.lexes of cobalt(II), nickel(II), copper(II) and cadm.um.II) have been synthesized with 3benzyl1H4[(2 m.thoxybenzylidine) am.no]1, 2, 4triazole5 thione (m.T), 3bezyl1H4[(4chlorobenzylidine) am.no]1, 2, 4triazole5thione (CBT), 3benzyl 1H4[(4nitrobenzylidine)am.no]1, 2, 4triazole 5thione (NBT) and dehydroacetic acid sodium.salt (Nadha). The m.xed ligand com.lexes have been characterized by elem.ntal analysis, spec troscopic spectral m.asurem.nts (IR, UVVis.), m.lar conductance, m.gnetic m.asurem.nts and therm.l studies. The stoichiom.try of these com.plexes is m.L1:L2 = 1:1:1, 1:2:1 or 1:1:2 where L1 = NBT, CBT and m.T and L2 = Nadha. Tetrahedral structure was proposed for all Cd(II) m.xed ligand com.lexes while the square planar geom.try was proposed for Cu(II) m.xed ligand com.lex with NBT. Octahedral structure was proposed for Ni(II), Co(II) m.xed ligand com.lexes and Cu(II) m.xed ligand com.lexes with CBT and m.T ligands. The therm.l decom.osition study of the prepared com.lexes was m.nitored by TG, DTG and DTA analysis in dynam.c nitrogen atm.sphere. TG, DTG and DTA studies confirm.d the chem.cal form.lations of theses com.lexes. The kinetic param.ters were determ.ned from.the the therm.l decom.osition data using the graphical m.thods of CoatsRedfern and Horwitzm.tzger. Therm.dynam.c param.ters were calculated using standard relations.

The heritage buildings at the west bank of Luxor were affected by expansive Esna shale differentially from.site to others. The role of expansive Esna shale was evaluated by using X-ray diffraction spectra (particle size, strain), X-ray fluorescence, basic soil properties test, swelling test, soil classification, and unconfined com.ression test. Three different sam.les were exam.ned to determ.ne the expansive role in the deterioration of heritage sites. The expansive is high, according to: (a) Soil classification based on plasticity index, (b) Classification chart based on the liquid lim.t and plastic index, (c) Classification chart based on clay content and activity, (d) Soil classification, and (e) Swelling pressure which determ.nes the safety factor. In addition, expansive classification assesses that Esna shale Form.tion is one of environm.ntal hazards characterized by dam.ge role near Nile flood and irrigation area and characterized by deterioration role in heritage sites far from.Nile flood and irrigation area. This paper refers to evaluation as a m.in process of integrated conservation approach.
