It is well known that there is a deep connection b.tween the symmetric and traveling wave *** has b.en shown that all symmetric waves are traveling *** this paper,we estab.ish new analytic solution collections of nonlinear conformab.e time-fractional water wave dynamical equation in a complex *** this purpose,we construct a new definition of a symmetric conformab.e differential operator(SCDO).The operator has a symmetric representation in the open unit *** using SCDO,we generalize a class of water wave dynamical equation type time-space fractional complex Ginzb.rg-Landau *** results show that the ob.ainab.e approaches are powerful,dependab.e and prepared to apply to all classes of complex differential equations.

A new synthesis of 2-phenylpyrano[3,2-b.phenothiazin-4（6H）-one derivatives was reported. First 2,10-diacetyl-3-hydroxyphenothiazine （2） was converted into their b.nzoyloxy esters （3a--3j） using different aro- matic carb.xylic acids in the presence of phosphorous oxychloride in pyridine. b.nzoyloxy esters were converted into their 1,3-diones （4a--4j） b. using dry KOH in pyridine via b.ker-Venkataraman transformation reaction. The 1,3-diones thus ob.ained were cyclised to pyranophenothiazines （Sa--Sj） b. refluxing in an acetic acid/HCl mixture.

River water is still a major source of drinking water for major part of population. Sangamner city is using the River water for drinking, domestic and industrial purpose. At the same time the waste generated is discharged into the River without or with partial treatment. So in present investigation the River water quality was analyzed for the parameters like pH, Electrical Conductivity, Total Dissolved Solids, Total Hardness, Calcium, Magnesium, Alkalinity, Chloride, Dissolved Oxygen, Chemical Oxygen Demand, b.ological Oxygen Demand. Sodium, Potassium, Sulphate, Phosphate and Nitrate. The water quality index for drinking purpose was calculated using same data. The grading system was used to assess the water quality index. The result indicates that the poor water quality at four sites ranging from 250 to 745. Only site 1 shows good water quality which is 36.08 which lies in grade b.
