the complexes of salicylaldehyde thiosemicarbazone with Pd, Cu and Ru were prepared. the prepared complexes were chara.t.rized by spectroscopic, element and thermal analyses and D.C. conductivity measurements. the a.t.microbial a.t.vity of all the prepared compounds against gram-positive, gram-negative and fungi was studied. From these studies, it has been obtained that the ligand is bonded to the metals through O, N and S, but to palladium in [Pd (H//2L//2)] Cl//2 only through N and O. Biological studies confirm that the organic effect on both gram-positive and gram-negative ba.t.ria is very weak and their complexes have no effect on fungi, but Cu-complex has strong influence on both types of ba.t.ria.

this paper examines the transport analysis, including both heat transfer and mass transfer, in hybrid nanofluid flow containing gyrota.t.c microorganisms towards a curved oscillatory surface. the influence of magnetic fields is also inspected in terms of their physical chara.t.ristics. to depict the phenomena of transport, modified versions of both Fick's and Fourier's laws are used. Additionally, the chara.t.ristics of both heterogeneous and homogeneous chemical rea.t.ons are also incorporated. Utilizing a curvilinear coordinate system, the flow problem is formulated as pa.t.al differential equations(PDEs)for momentum, concentration, microorganism field, and energy. An analytical solution to the obtained flow equations is achieved utilizing the homotopy analysis method(HAM).the effects of significa.t.flow parameters on the pressure and microorganism fields, velocity, oscillation velocity, concentration, and temperature distributions are shown via graphs. Furthermore, the variations in skin friction, mass transfer rate, heat transfer rate, and local motile number due to different involved parameters are presented in tables and are analyzed in detail. Graphical results indicate that the curves of velocity and temperature fields are enhanced as the values of the solid volume fra.t.on variables *** is also verified that the concentration rate field decreases as the values of the homogeneous rea.t.on strength parameter and the radius of curvature parameter increase, and it increases with the Schmidt number and the heterogeneous rea.t.on strength *** outcomes show a favorable response of the motile number to advanced values of the Peclet number, the Schmidt number, the microorganism difference parameter, and the bio-convective Lewis number.

the dynamic leaching of la.t.anides from a west desert phosphate ore, Egypt (Abu ta.t.r) by hydrochloric acid, nitric acid and sulfuric acid solutions was investigated in this study as a function of acid concentration, flow rate and the presence of some additives such as boric acid. Also the kinetics of leaching of la.t.anides was investigated as a function of temperature. It was found that the leaching process could be described by a shrinking-core model, with a.t.vation energy about 5.9, 13.8 and 21.9 kJ/...

Elevated salinity imposes osmotic and ion toxicity stresses on living cells and requires a multitude of responses in order to enable pla.t.survival. Building on earlier work profiling transcript levels in rice （Oryza sativa） shoots of FL478, a sa.t.tolera.t.indica recombina.t.inbred line, and IR29, a sa.t.sensitive cultivar, transcript levels were compared in roots of these two accessions as well as in the roots of two additional sa.t.tolera.t.indica genotypes, the landrace Pokkali and the recombina.t.inbred line IR63731. the aim of this study was to compare transcripts in the sensitive and the tolera.t.lines in order to identify genes likely to be involved in pla.t.salinity tolerance, rather than in responses to salinity perse. transcript profiles of several gene families with known links to salinity tolerance are described （e.g. HKts, NHXs）. the putative function of a set of genes identified through their sa.t.responsiveness, transcript levels, and/or chro- mosomal location （i.e. underneath QtLs for salinity tolerance） is also discussed. Finally, the parental origin of the Sa.t.l region in FL478 is further investigated. Overall, the dataset presented appears to be robust and it seems likely that this system could provide a reliable strategy for the discovery of novel genes involved in salinity tolerance.

this paper investigates the free vibration and transient response of interconnected structures including double curved beams and intermediate straight beams,which are all constructed from functionally graded porous(FGP) materials. the strain potential and kinetic energies of each beam along with the work done by the external force are calculated. Additionally, a higher-order beam element is introduced to derive stiffness and mass matrices, along with the force vector. the curved and straight beams are discretized, and their assembled stiffness, mass matrices, and force vectors, are *** conditions at the joints are used to derive the total matrices of the entire structure. Subsequently, the natural frequencies and transient response of the system are determined. the accuracy of the mathematical model and the self-developed computer program is validated through the comparison of the obtained results with those of the existing literature and commercial software ANSYS, demonstrating excellent ***, a comprehensive study is conducted to investigate the effects of various parameters on the free vibration and transient response of the considered structure.
