Asian Journal of Conservation Biology , 2013,
Abstract: Food habits of dhole Cuon alpinus studied in Kalakad-Mundanthurai Tiger Reserve from January 2010 to July 2010 by analyzing 78 scats. Ten prey species were consumed by dholes in which Sambar was consumed highest percentage (30.77%) followed by wild pig (23.08%) and lowest was Jungle fowl (0.063%). In terms of biomass contribution sambar was highest (78.70%) while jungle fowl was lowest contribution (3.85%). The total prey biomass consumed by dhole was 191.72 kg during our study period. This study will give basic information on food habits of dhole and also gives basic idea for better management strategies to protect this elegant carnivore.

Asian Journal of Conservation Biology , 2013,
Abstract: Eastern Himalayan biodiversity hotspot is rich in pheasant diversity, as eleven of the seventeen pheasant species in India occur here. Despite the richness, these pheasants have been least studied in their natural habitats and their current population status, ecology and behavioural patterns are unknown. We estimated abundance, habitat use and activity pattern of three pheasants, i.e. Red Jungle Fowl Gallus gallus (RJF), Kalij Pheasant Lophura leucomelanos (KP) and Grey Peacock Pheasant Polyplectron bicalcaratum (GPP) in Pakke Wildlife Sanctuary and Tiger Reserve, Arunachal Pradesh. Data collected from line transects and camera traps were used for estimating abundance, habitat use and activity patterns. Program Oriana 4.2 was used to determine the activity pattern of three species. Questionnaire survey was conducted around the protected area to determine the conservation threats for these species. Red jungle fowl had the highest density of 12.9 individuals/km2 and a photographic rate of 3.19/100 trap nights among all the pheasants. Shrub cover, litter cover and grass cover were positively associated (p<0.001) with pheasant detections, where as disturbance (p<0.001) was negatively correlated. 60% of habitat overlap was observed between KP and RJF. Dillenia indica dominated habitats were significantly correlated with pheasants detections (R=0.34, p<.0001). The mean activity of GPP, RJF and KP were 6.30 hrs ± 3.37 hrs, 7.49 hrs ± 0.14 hrs and 8.29 hrs ± 0.18 hrs respectively. Additional studies on current status of these species and management plans are critical for pheasant conservation in this critical biodiversity hotspot.

Journal of Biological Sciences , 2010,
Abstract: In the present study, the soil samples were collected from Corn and Soya fields; near MCAS. Actinomycetes strains were isolated in specific medium using Arginine-Glycerol-Salt (AGS). These Actinomycetes were screened with regard to potential against Gram-positive and Gram-negative bacteria. The purified Actinomycetes strains were performed in biochemical tests such as, Fermentation of citrate, Starch hydrolysis, Vogus-proskauer, Triple sugar iron test etc. The positive isolate was immobilized using sodium alginate beads and the immobilized cells were cultivated in specific fermentation liquid medium for 120 h. Antibacterial compound was purified from the filtrate by solvent extraction method. A comparative study on the total antibiotic sensitivity of the free cells and immobilized cells showed that the immobilized strains were found to be effective against the tested microorganisms. The immobilized cell of Actinomycetes was found to be more efficient for the production of secondary metabolites with batch fermentation. The Actinomycetes strains were prepared in crude protein and the crude protein was determined by using SDS PAGE method. From the results, we are concluded that the positive immobilized Actinomycetes strain showed high antibacterial activity against tested pathogens.
A Study on Catalase Activity and its Genetic Polymorphism in Diabetes Mellitus Patients
K. Dhanapal,N. Selvan,V. Dhananjeyan
Journal of Biological Sciences , 2010,
Abstract: This study aimed to investigate on catalase activity and genetic polymorphism in diabetes patients, the blood sample were collected from 20 type II diabetic patients attending the outpatient department and admitted to the RMMCH. The age of patients ranged from 40-65 years of both sexes. Reactive oxygen species generated by hyperglycemia modify structure and function of lipids, proteins and other molecules. This study was undertaken to investigate the association between gene polymorphisms of selected antioxidant enzymes. The 20 type 2 diabetes mellitus patients were analyzed for SNP in catalase gene. Restricted fragment length polymorphism studies showed 80% of the patients were TT genotype and 20% were of heterozygous genotype. No AA genotype was observed in our group of study. Observed that patients with T allele had significantly lower fasting plasma glucose, RBC catalase activity and HbA1c where as heterozygous had higher FPG, RBC catalase activity high and HbA1c. It is suggestive of possible association of heterozygocity with poor glycemic control and high catalase activity. It has been observed that the level of enzyme was found to be significantly high in heterozygous group. High (concentration) activity may be secondary to high oxidative stress as a result of poor glycemic control. In heterozygous patients the association of high catalase activity with this SNP should be carefully considered because early study has reported that there is no statistically significant difficult association of CAT alleles and this activity.

International Journal on Applications of Graph Theory in Wireless ad hoc Networks and Sensor Networks , 2013,
Abstract: Wireless mesh networking has transpired as a gifted technology for potential broadband wireless access.In a communication network, wireless mesh network plays a vital role in transmission and are structured ina mesh topology. The coordination of mesh routers and mesh clients forms the wireless mesh networkswhich are routed through the gateways. Wireless mesh networks uses IEEE 802.11 standards and has itswide applications broadband home networking and enterprise networking deployment such as Microsoftwireless mesh and MIT etc. A professional Qos provisioning in intra cluster packet level resourceallocation for WMN approach takes power allocation, sub carrier allocation and packet scheduling. Thisapproach combines the merits of a Karush-Kuhn-Tucker (KKT) algorithm and a genetic algorithm (GA)based approach. The KKT algorithm uses uniform power allocation over all the subcarriers, based on theoptimal allocation criterion. The genetic algorithm is used to generate useful solutions to optimization andsearch problems and it is also used for search problems. By combining the intrinsic worth of both theapproaches, it facilitates effective QOS provisioning at the packet level. It is concluded that, this approachachieves a preferred stability between system implementation and computational convolution.

Journal of Plant Breeding and Genetics , 2013,
Abstract: Selection of genotypes with adequate combination of traits with high yield at the appropriate density level increased the productivity in amaranth. The study was therefore undertaken to estimate genetic attributes of different amaranth genotypes and to identify and select genotypes with adequate trait combination for improvement in yield. In grain amaranthus (Amaranthus hypochondriacus L.) ten genotypes were evaluated for twelve characters under four plant density levels viz., very high (D1), high (D2), normal (D3) and low plant density (D4) to study the different selection parameters for grain yield and its eleven contributing morphological and quality traits. The study was conducted at College Orchard, Department of Horticulture, Pandit Jawaharlal Nehru College of Agriculture and Research Institute, TNAU, Karaikal during rabi 2007. The results revealed that the GCV was maximum in high plant density when compared to very high, normal and low plant density levels for the characters viz., fresh weight of the inflorescence, length of the rachis per inflorescence, grain yield per plant and total carbohydrates. Leaf area at 50 per cent flowering, fresh weight of the inflorescence, number of secondary branches per inflorescence and total carbohydrates are recorded high magnitude of genetic variability in combination with high heritability and genetic advance as per cent of mean in all the four plant density levels.

MIXED CONVECTION IN A LID-DRIVEN CAVITY UTILIZING NANOFLUIDS
Muthtamil Selvan
CFD Letters , 2010,
Abstract: Heat transfer enhancement in a two-sided lid-driven cavity utilizing nanofluids is investigated for various pertinent parameters. A model is developed to analyze the behaviour of nanofluids taking into account the solid volume fraction . The top and bottom moving walls are maintained at different constant temperatures while the vertical walls are adiabatic. The numerical approach is based on the finite volume technique with a staggered grid arrangement. The SIMPLE algorithm is used for handling the pressure velocity coupling. Numerical solutions are obtained for wide range of parameters and copper water nanofluid is used with Pr=6.2. Numerical results show the inclusion of nanoparticles into the base fluid has produced an augmentation of the heat transfer coefficient, which has been found to increase appreciably with an increase of particles volume concentration. Detailed results are presented in the form of streamlines, isotherms and average Nusselt numbers.

Journal of Food Technology , 2013,
Abstract: A study was carried out to determine the influence of different concentration and contact time combinations of lactic acid solutions on microbial, sensory and physico-chemical characteristics of buffalo offals viz., head meat, heart, liver and rumen. The following concentration and contact time combinations were used: 1% lactic acid for 20 sec, 1.5% lactic acid for 15 sec and 2% lactic acid for 10 sec. A total of 80 buffalo offal samples (20 numbers of each kind) were collected from a buffalo offal market and subjected to immersion treatments. Water washed offal pieces were used as controls. Sensory evaluations were conducted using a sensory panel comprising postgraduate students and scientists of Livestock Products Technology division, Indian Veterinary Research Institute (India). The data obtained were subjected to statistical analysis using the Analysis of Variance (ANOVA). Mean log10 reductions (CFU g 1) achieved, based on the different treatments and kinds of buffalo offal were between 0.22 and 1.05 for total viable counts; 0.22 and 1.19 for coliforms counts and 0.25 and 0.98 for staphylococcal counts. Immersion in 2% lactic acid solution for 10 sec gave the best overall reduction effect. Sensory evaluations recorded minimal effects of treatments on buffalo offals. These findings show that immersion in 2% lactic acid for 10 sec is suitable for decontamination of Buffalo Offals.
