A study on intertidal rocky shore fauna in Burmanella, South Andaman

Priyanka Devi, Revathi, K., Senthil Kumari, S. and Subashini, A.

The Andaman & Nicobar coast constitute various ecological habitats that support large groups of marine organisms. These habitats help to unravel the faunal similarities and special features in the faunal composition among regions and habitats examined. The faunal diversity on the rocky shores is generally governed by the tides. The animals on the rocky shore undergo stress due to changing environmental factors. In the present study an attempt was made to study the distribution of marine fauna along the rocky shore of Burmanella coast. During the study two sites were selected and named a Stn 1(N11˚30.998ꞌ and E92˚44.100ꞌ) and Stn 2 (N11˚31.606ꞌ and E92˚43.464ꞌ). The present study investigated rich diversity of macro faunal groups which included echinoderms, molluscs, crabs, polychaetes etc.

Beneficial effect of organic fertilizers on the yield characters, microbial dynamics and soil nutrient status

Tensingh Baliah, N., Andal Priya, S. and Priya, C.

The application of organic fertilizers had a positive effect on yield characters such as number of flower buds, number of fruits and length of fruits in Okra. The results revealed that flower formation was higher in plants amended with organic manure followed by Farmyard manure (FYM). The fruit length and fruit weight were significantly increased with the soil amended with vermicompost. The fruit weight was directly correlated with the harvest index of okra. The organic fertilizers significantly increased the bacterial and fungal population in the amended soil than control soil. The vermicompost amended soil had the maximum population level of both bacteria and fungi followed by organic manure. The positive effect of organic fertilizers also reflected the soil nutrient content also. There was a significant difference was observed on the macronutrients such as N and P in the organic fertilizer amended soil over the control. From the present study, it is clear that the amendment of organic fertilizers had beneficial effect on yield characters of okra. Further, the beneficial effect was not only yielding but also in the soil characters as well as nutrient status of the soil also. The cumulative effect of soil characters boost up the yield characters of okra.

The peels from fresh and sound tomatoes were carefully removed and dried in a tray drier at 80ºC for 6 hours, cooled, milled and sieved. Tomato soup was prepared using tomato peel as a thickener. Bulk density, swelling power, water absorption and oil absorption capacity of the peel powder was 10, 4.56, 6.16 and 7.83 respectively. The peel powder was also tested on other physico-chemical parameters. The overall acceptability of the soup was 8.4.

Formulation of chocolate icecream using germinated brown rice milk

Anjana, R., Mahalaxmi, S., Sandhya, P.S. and Lakshmypriya, S.

Ice cream is a frozen dessert usually made from dairy products Brown rice milk is a useful dairy substitute. During the process of germination, Gama Amino Butyric Acid (GABA) levels and the amount of important nutrients like calcium, fibre and potassium have been known to increase. The study aimed at formulating Germinated Brown Rice (GBR) milk ice cream as a non-dairy substitute, to be consumed by the people who are lactose intolerant and those who are allergic to soy. The GBR ice cream was primarily prepared by extracting GBR milk and by combining methods of heating, condensation, homogenization and freezing using standard procedures. A variation with a combination of GBR milk and dairy milk in the ratio of 1: 1 was also prepared. The experimental products were analyzed for Physico- chemical tests like TSS, Protein, Fat, SNF and Weight by Volume using standard AOAC methods. Sensory evaluation was conducted with the help of 20 semi-trained panelists for color, flavor, taste, texture, mouth feel, sweetness, after taste and over all acceptability of the product on a standard 9 point hedonic scale. The results for GBR milk ice cream revealed the following: protein 3.8%, TSS 33±5, Fat 10.56%, SNF 25.44%, Weight by volume 535.2. Similarly the content in variation was observed to be: protein 4%, TSS 33±5, Fat 13.88%, SNF 22.12%, Weight by volume 546. The products were well accepted and had an overall acceptability of 8.75 for 100% GBR milk ice cream and 8.5 for 50% GBR milk ice cream. Thus the present study qualifies to identify GBR milk as the best non-dairy substitute in ice cream preparation.

Synthesis and biological activities of analogs of aryl tetralone

Chaitramallu, M., Devaraju kesagodu, Dakshayini chandra shekarachar and Dr. Ranjini

The aryl tetralone as potential antimitotic agents were synthesized in four step reactions using Grignard reagent. The first step is the synthesis of trimethoxy phenyl naphthol (2a-f) by the reaction of substituted tetralone with 3, 4, 5-trimethoxy 1-bromobenzene in magnesium metal using tetrahydrofuran as a solvent. The resulted phenyl naphthol was hydrogenated to give phenyl tetralin 3(a-f). The substituted phenyl tetralone were prepared by the oxidation of trimethoxy phenyl tetralin 4(a-f). The structures of the synthesized compounds were confirmed by spectral and elemental analysis data. The synthesized compounds were also screened for their antidiabetic activity. It is noteworthy that compounds 4d possessed excellent antidiabetic activity, 4b and 4c showed considerable activity, and remaining 4a possessed least activity. Compound 4d was immense to show high antibacterial and antifungal activity against all bacterial and fungal strains compared with standard chloramphenicol and nystatin, respectively.

Detection and removal of impulse noise for cattle identification using fuzzy methods

Anusha Edwin and Jerrin Thomas Panachakel

Muzzle patterns of cattle are uneven features of their skin surface. They are different from each other like finger prints of human. Hence these muzzle patterns can be used to identify cattle. Noise is any unwanted component in an image. It is important to eliminate noise in the images before some sub-sequent processing such as edge detection, image segmentation and pattern recognition. This paper proposes a method for salt and pepper noise removal based on mathematical methods using fuzzy rules from muzzle images. The proposed Fuzzy operator consists of two modules viz. Detection module and Adaptation module. For fuzzy reasoning, a triangular shaped fuzzy set described by a two parameter membership function is used. For each pixel element 13 fuzzy rules are applied and an output y is produced in detection module. In adaptation module y is further reduced and it is added with input pixel value to get output pixel value. The proposed method is able to perform a very strong noise cancellation while preserving muzzle image details. The Fuzzy Filter is compared with other non-linear filters such as Median Filter, SDROM Filter, PSM Filter and is getting better results in terms of PSNR values and SSIM Values.
