2-amino-4,6-diethyl-5-(4’-sulphonamoyl)azopyrimidines were synthesized by condensation of 2-(4’-sulphonamoyl)hydrazono-3,5-heptanedione with Guanidine Nitrate in the molar ratio 0.01M yield the corresponding synthesized compounds respectively. The following sulpha drugs viz. (Sulphanilamide, Sulphaguanidine, Sulphadiazine Sulphadimidine, Sulphathiazole and Sulphapyridine etc.) were used in this synthesis. The structure of synthesized compounds was elucidated by elemental analyses, UV-vis, FT-IR, 1 H, NMR and mass spectrometry and purity of newly synthesized compounds were checked by TLC.The New products have been assessed for antifungal and antibacterial activities against certain microorganism.

The aim of this study was modeling of ambient air pollutants through ANN in industrial area of Ujjain city in India and the study was carried out on modeling of air pollutants like SPM and RSPM using Artificial Neural Network. Artificial neural networks (ANN), whose performances to deal with pattern recognition problems is well known, are proposed to identify air pollution sources. The ANN system was run by giving the inputs of meteorological data’s and giving the outputs of concentration of various pollutants and accordingly the estimation of Errors was done by this study. The monthly data’s in year from 2009 -2012 of meteorological data’s like Temperature, Humidity, wind pressure and rainfall and the pollutants concentration were collected from the State Pollution Control Board. The ANN system used, as shown in figure 1, analyses all these data’s and finds the error coming during the experiment. The study estimated the Mean Square Error (MSE) from the inputs and outputs which were given to ANN in the industrial area of Ujjain City in India was found satisfactory being in the range of 0.001-0.003. The results shown here indicate that the neural network techniques can be useful tool in the hands of practitioners of air quality management and prediction. The models studied in this study are easily implemented, and they can deliver prediction in real time, unlike other modeling techniques.

The study of structural interactions by means of molar volume have received vital importance in physical chemistry. The apparent and partial molar volume of electrolytic solutions have proven to be a very useful tool in elucidating the solute-solute, solutesolvent and solvent-solvent interactions occurring in solution 1-5. In present investigation the molar volumes of non-electrolytes (Glucose as a bio molecule) in solution found little and nearly linear with concentration6 .

Most heavy metals are well-known toxic and carcinogenic agents and when discharged into the wastewater represent a serious threat to the human population and the fauna and flora the receiving water bodies. Microalgae culture offers an interesting step for wastewater treatments, because they provide a tertiary biological treatment coupled with the production of potentially valuable biomass, which can be used for several purposes. Microalgae cultures offer an elegant solution to tertiary and quandary treatments due to the ability of microalgae to use of cell wall biosorption mechanism. Their capacity to remove heavy metals is also affected by pre-treatment of biomass, surrounding condition such as pH, light intensity, temperature and biotic factors. In the current review we will highlight on the role of micro-algae in the treatment of wastewater.

In the work iodine amount in vegetative and generative organs of medicinal plants Berberis Vulgaris L. and Xanthium Strumarium L. has been studied by ion chromatography. It was found that iodine amount in stalk of Berberis Vulgaris L. by 3 times and in leaf by 23 times less than that in root, and in fruit it makes 6,2±0,5 mg. It was revealed that in root, stalk and leaf of Xanthium Strumarium L. iodine amount is almost the same (677,8±39,4), and in fruit – 80 % (540,4±28,4) of vegetative organs.
