Ricci Solitons in -Sasakian Manifolds

Abstract: We study Ricci solitons in 𝛼-Sasakian manifolds It is shown that a symmetric parallel second order-covariant tensor in a 𝛼-Sasakian manifold is a constant multiple of the metric tensor Using this, it is shown that if ℒ𝑉𝑔

Three dimensional MHD flow of couple stress Casson fluid past an unsteady stretching surface with chemical reaction

Abstract: The analysis of three dimensional MHD flow of couple stress Casson fluid past an unsteady stretching surface with the effect of chemical reaction and convective boundary condition has been considered. The governing partial nonlinear differential equations are treated with similarity variables reduced into them ordinary deferential equations. Runge Kutta Fehlberg fourth fifth order method is to employed to the resultant equation for numerical solution. The results are then discussed graphically in the form of velocity, temperature and concentration profiles for several physical parameters of interest. From the plotted results it is observed that the larger values of Casson parameter decrease velocity components. Whereas, solutal boundary layer thickness decreases for larger values of chemical reaction parameter and Schmidt number. The present results are compared with the existing limiting solutions, showing good agreement with each other.

Studies on Synthesis and Pharmacological Activities of 3,6-Disubstituted-1,2,4-triazolo[3,4-b]-1,3,4-thiadiazoles and Their Dihydro Analogues.

Abstract: Several 3,6-disubstituted-1,2,4-triazolo[3,4- b ]-1,3,4-thiadiazole and their dihydro analogues were synthesized from hetero aromatic acids and hetero aromatic aldehydes, respectively, by microwave-assisted dry media and conventional methods. Elemental analysis, IR, 1 H NMR, 13 C NMR and mass spectral data elucidated the structures of all newly synthesized compounds. Synthesized compounds are studied for their antibacterial, antifungal, anti-inflammatory and analgesic activities. Some of the tested compounds showed significant pharmacological activities.

Chemical treatment of zinc surface and its corrosion inhibition studies

Abstract: The surface treatment of zinc and its corrosion inhibition was studied using a product (BTSC) formed in the reaction between benzaldehyde and thiosemicarbozide. The corrosion behaviour of chemically treated zinc surface was investigated in aqueous chloride-sulphate medium using galvanostatic polarization technique. Zinc samples treated in BTSC solution exhibited good corrosion resistance. The measured electrochemical data indicated a basic modification of the cathode reaction during corrosion of treated zinc. The corrosion protection may be explained on the basis of adsorption and formation of BTSC film on zinc surface. The film was binding strongly to the metal surface through nitrogen and sulphur atoms of the product. The formation of film on the zinc surface was established by surface analysis techniques such as scanning electron microscopy (SEM-EDS) and Fourier transform infrared spectroscopy (FTIR).
