The effort summarized preparation of metal chelates containing 4-carboxaldehyde-2-pyrazolin-5-one Schiff bases as ligand. Structural and spectroscopic properties of Schiff bases as well as metal chelates were studied on the basis of NMR (13C) spectra, IR spectrum and elemental analyses....

As we know that, there is a vast water crisis in the world due to less availability of potable water. A device which converts the saline water into drinkable water by use of solar energy is called solar still. many researchers have worked on solar still to improve performance but no one has applied CFD simulation approach....

Soil erosion is a continuous natural phenomena and a part of soil formation process. But, unfortunately, human interfere with nature and accelerated soil erosion at so large extent that soil erosion became a serious problem all over the world today....
