Nanoparticulate systems have great potentials,being able to convert poorly soluble, poorly absorbed and labile biologically active substance into promising deliverable drugs. The core of this system can enclose a variety of drugs, enzymes, genes and is characterized by a long circulation time due to the hydrophilic shell which prevents recognition by the reticular-endothelial system. To optimize this drug delivery system, greater understanding of the different mechanisms of biological interactions, and particle engineering, is still required. Further advances are needed in order to turn the...

The present research work deals with the quality of underground well/tube well water and inter-relationship within the properties of well/tube well water samples. Representative water sample were collected and analyzed using the standard procedures of water analysis. Following the methods listed by Richards (1954), the accuracy and precision of the analyses were checked up. Statistical Study Of Water Analysis done by Dr. Kamlesh Patel.

An attempt has been made in the present investigations to study the quality of underground well/tube well water samples and their interrelationship between different ions which are present in irrigation water. About 84 underground water samples were collected from representative areas of Bechraji, Mehsana, Kadi and Vijapur Talukas of Mehsana district. Irrigation water samples were analyzed for Electrical Conductivity (EC), pH, Total Dissolved Solids (TDS), cations (Ca+2, Mg+2, Na+and K+) and anions (CO3-2, HCO3-1, Cl-1, and SO4-2). Various indices viz., Residual Sodium Carbonate (RSC), Sodium...
