Abstract: Absorption treatment of distillery effluent has great potential as a sustainable method as it is a low cost method. The aim of this investigation is to study the absorption treatment method for purification of distillery spent wash. For this, the study encompassing evaluation of reduction of various physical chemical parameters (pH, COD, TS, TDS, Ca, Mg, Na and K) of distillery spent wash was checked by passing effluent through the column of sand, activated charcoal and sand +activated charcoal (1:1) . The original distillery effluent was acidic (pH 4.7) and dark brown in color which often cause psychological fear in farmers for utilization. Treatment of spent wash with activated charcoal and sand +activated charcoal (1:1) exhibited maximum reduction in COD, TS, TDS, Mg, Na, Ca, and increase in pH toward pH 7. Treated spent wash resulted in a good growth of wheat seeds.

Abstract:The inhibiting effect of Janumet in 1 M HCl on the corrosion of mild steel was studied by potentiodynamic polarization (PDP), Scanning Electron Microscopy (SEM) and Fourier Transform Infrared Spectroscopy (FTIR) techniques. The results of potentiodynamic polarization showed that corrosion current density, icorr, decreases with increasing the concentration of organic inhibitors indicating a decrease in the corrosion rate as well as an increase in the inhibition efficiency of mild steel. The drug act as mixed type inhibitors, they retarded both cathodic and anodic reaction. The adsorption of Janumet on the carbon steel surface obeys Langmuir adsorption isotherm. Results from SEM and FTIR measurements confirmed well this behaviour.

Abstract: One of the reasons that the Fourier transform is so useful is that it converts operations on function in to different operations on the function.
In this paper we discuss some properties of differentiability of Fourier transform and we generalize the results that are stated by many other authors, and we give some propriety in Schwartz's space using the main result.

Abstract: Modern lubricating oil is made of base stock or base oil blended with a few ppm of chemical additives according to its grade and specific duty. During usage, lubricating oils undergo changes termed degradation and contamination, which render them ineffective for further application.
This research investigated the effect of two different solvent mixuresA=(xylene+butanol+methanol) and B=(xylene+butanol+isoprppanol) followed by bleatching on activated alumina as adsorbent material to produce lubricating oil.
To achieve this objective, firstly used oil was allowed to settled for (1hr), after being centrifuged at 1500rpm for 30 minutes then exposed to filtration on Buncher funnel with vacuum pump to remove impurities.
The results showed that all ratio ( 1:1,1:3 and 1:5) of solvent mixture  (A)  is the best performance with the maximum percent sludge removal. The characterization and physico-chemical properties showed that  the refined oil from solvent mixure (A)followed by treatment with activated alumina  have good properties with comparing to the stander specification of new lubricating oil .

Abstract: The inhibitive and adsorption properties of ethanol extracts of Delonix regia leaves were studied using gravimetric method of monitoring corrosion. Phytochemical analysis was carried out using fat free samples of the respective extracts. The results obtained indicated that ethanol extract of Delonix regia leaves is a good adsorption inhibitor for the corrosion of mild steel in H2SO4 solutions. The phytochemical screening proved that the leaf extracts are rich in alkaloids, flavonoids and tannins.The adsorption of the inhibitor on mild steel surface is spontaneous and supports the Langmuir adsorption models. From the values of free energy of adsorption, a physical adsorption mechanism has been proposed for the adsorption of the inhibitor on mild steel surface.
