Laser action in methyl methacrylate （mmA） co-doped with sulforhodamine B and crystal violet dyes was investi- gated. The dye mixture was incorporated into a solid polymeric matrix and was pumped by a 532-nm Nd：YAG laser. Distributed feedback dye laser （DFDL） action was induced in the dye mixture using a prism arrangement both in the donor and acceptor regions by an energy transfer mechanism. Theoretically, the characteristics of acceptor and donor DFDLs, and the dependence of their pulse widths and output powers on acceptor-donor concentrations and pump power, were studied. Experimentally, the output energy of DFDL was measured at the emission peaks of donor and acceptor dyes for different pump powers and different acceptor-donor concentrations. Tuning of the output wavelength was achieved by varying the period of the gain modulation of the laser medium. The laser wavelength showed continuous tunability from 563 nm to 648 nm.

The cultivation of aerobic granules in sequencing batch reactor for the biodegradation of p-cresol was studied. The reactor was started with 100 mg/L of p-cresol. Aerobic granules first appeared within one month of start up. The granules were large and strong and had a compact structure. The diameter of stable granules was in the range of 1-5 mm. The integrity coefficient and granules density was found to be 96% and 1046 kg/m3, raspectively, The settling velocity of granules was found to be in the range of 2×10^-2-6×10^-7 m/sec. The aerobic granules were able to degrade p-cresol upto 800 mg/L at a removal efficiency of 88%. Specific p-cresol degradation rate in aerobic granules followed Haldane model for substrate inhibition, High specific p-cresol degradation rate up to 0,96 g pcresol/（g ***） were sustained upto p-cresol concentration of 400 mg/L, Higher removal efficiency, good settling characteristics of aerobic granules, makes sequencing batch reactor suitable for erLhaneing the microorganism potential for biodegradation of inhibitory compounds.

AIm: Sargassum wightii Greville is a marine brown alga belonging to the Sargassaceae family which has about 200 species. The ethanolic extract of the whole dry plant powder contained numerous phytoconstituents, including flavonoids. The study was focused on the anticancer activity of Sargassum wightii in mice. mETHOD: The ethanolic extract of Sargassum wightii(EESW) at two dose levels was used to examine the anticancer activity in mice using DAL cell lines to induce cancer. The body weight, viable and non-viable tumor cell count, mean survival time, increase in life span, and hematological parameters were observed for anticancer activity of EESW. RESULTS: The intraperitoneal inoculation of DAL cells in mice significantly increased cancer cell count. The decrease in the cancer cell number observed in the EESW-treated group cancer animals indicates that the test drug has a significant inhibitory effect on the tumor cell proliferation. Treatment with EESW also showed a significant decrease in tumor weight, and hence increased the lifespan of DAL-treated mice. In addition, EESW administration significantly restored the hematological parameters in DAL-treated mice. CONCLUSION: The present study results suggest that administration of extract offers enhanced antioxidant potential. Therefore it can be concluded from this study that EESW possesses anticancer activity.
