Only fertilizer has significant effect on the growth of Eucalyptus tereticornis and Eucalyptus earnaldulensis seedlings. For boosting the growth and reducing the nursery period by about a months time it is recommended to adopt A4 (0.4 gm Urea, 1 gm Superphosphate and 0.3 gm Muriate of Potash) for Eucalyptus tereticornis and AS (0.6 gm Urea, 1.5 gm Superpbosphate and 0.45 gm Muriate of Potash) for Eucalyptus carnaldlilensis. The cost of fertilizer will work out to Rs. 4/- for 1000 containers seedlings for A4 but there is a saving of Rs. 18/- for Eucalyptus teretieornis. In the case of Eucalyptus carnaldulensis the cost of fertilizer per 1000 seedlings for A5 works out to Rs. 6/- but the maintenance cost is reduced by Rs. 16/-.

The Separate Energy Storage Device (SESD) based Dynamic Voltage Restorer (DVR) used to protect consumers from the grid voltage fluctuations like Long and Short-Duration Voltage Variations. This paper analyses the operation principle of the SESD based DVR and its design is based on simple PI control method and decision making switch to compensate Long and Short-Duration Voltage Variations. During short-duration voltage variation super capacitor and fuel cell hybrid system is used to compensate the fault. In the same way during long-duration voltage variation photovoltaic (PV) system or backup battery or other grid is used to compensate the fault based on the availability. Using MATLAB/SIMULINK, the models of the SESD based DVR is establish, and the simulation tests are performed to evaluate the system performances.

Growth of biofouling microorganisms in surfaces of poultry, marine and other ecosystems is one of the major issues. Thus it is essential to control the growth of biofouling bacterial growth in surface of biological ecosystem. The present study has aimed to isolate novel antifouling compound from marine actinobacterial isolates. A total of 55 actinobacteria were isolated from Palk Strait coastal region (Bay of Bengal), Tamilnadu, India. All of them were preliminarily screened for their antifouling activity against six different biofouling bacterial (BFB) species isolated from poultry farms by cross streak plate method. Among them, 20 isolates possessed antibacterial activity against biofouling bacteria. From the 20 antifouling compound producers, 10 actinobacterial isolates were selected for further confirmation of antifouling compound production and their antifouling efficacies by shake flask culture method. Of them, one potential strain VS6 was found to be more active against all the six BFB. Thus, the result of the present study represents that the coastal areas of Tamil Nadu are rich in antifouling compound producing actinobacteria.Keywords

Totally, 82 actinobacteria were isolated from the marine sediment samples of Bay of Bengal, east coast of Tamilnadu, India. Of 82 isolates, 21 (26%) actinobacteria were possessed antibacterial activity against fish pathogenic bacteria namely Vibrio alginolyticus, V. parahaemolyticus, V. cholera, Aeromonas sp. and Pseudomonas sp. Among 21 antagonistic isolates, the isolate ECR77 and ECR 64 showed good inhibitory activity against test pathogens. The crude antibacterial compounds from the potential antagonistic isolates were extracted using different solvents after submerged fermentation. Of the various solvent extracts tested, ethyl acetate extract was showed good antibacterial activity against V. alginolyticus, V. cholera and Pseudomonas sp. The potential antibacterial compound producing isolates were characterized by using standard methods of ISP (International Streptomyces Project) and tentatively identified as Streptomyces sp.Keywords

The terrestrial soil sample was collected from Orathanadu, Thanjavur (Dt.), Tamilnadu, India. Physical and chemical characteristics of soil samples such as pH, electrical conductivity (EC), calcium (Ca2+), magnesium (Mg2+), bicarbonate (HCO3-), chloride (Cl-), total organic carbon, available nitrogen (N), phosphorus (P2O5) and potassium (K2O) were analyzed. A total of 10 actinobacteria were isolated from the terrestrial soil sample and they were characterized based on the morphological and biochemical properties. Among 10 isolates, each one was belonged to Actinobispora sp., Actinosynnema sp., Actinoplanes sp., Agromyces sp., Actinomadura sp., Jonesia sp., Catellatospora sp., Micromonospora sp., Microtetrospora sp. and Nocardia sp. Antibacterial activity of actinobacteria were tested against five different human pathogenic bacteria such as Salmonella typhi, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Enterobacter aerogenes. Further, the purification of antibacterial compound was performed by using thin layer chromatography and the functional groups of bioactive compounds were determined by FT-IR and UV spectral studies.Keywords

Business Enterprise has been globalised with revolutions from the E-banking and the way banking transactions are done. The cost of delivering banking services and products has substantially reduced by using E-Banking channels than traditional channels. This has encouraged the Banks for technological change at a faster pace and across the geography. E-banking technologies have proliferated in recent years, and the availability of a wide range of products has led to increasing adoption among consumers. The objectives of the research established revolve around the selected demographic variables like education, age, occupation and monthly income with regard to the satisfaction level of the respondents. The main finding of the study was that among the various demographic variables, only occupation and income of the banking customers influenced their satisfaction level significantly towards e-banking servicesKeywords

The design of an adaptable assembling framework (FMS) includes circulating various assets for accomplishing most extreme effectiveness. To give an assortment of items to clients the FMS has made a noteworthy arrangement of operational changes. Among this, format arranging is progressively significant in accomplishing profitability of FMS. The issue of this sort is combinatorial in nature and observed to be Non-deterministic Polynomial (NP) complete. This paper centers the circle design arranging of a FMS with the point of limiting the transportation remove and the backtracking separations of the Automated Guided Vehicles (AGV) utilizing the half breed Scatter Search - Particle Swarm Optimization calculation (SS-PSO). Since the Loop format has moderately low beginning expenses and contains couple of material taking care of connections with higher adaptability. SS-PSO works on binding together standards dependent on vital structures contrasted with other metaheuristic calculations, for example, GA, PSO and so forth. Half breed SS-PSO approach is connected to seven and nine machines circle format issue. It is discovered that the proposed calculation furnishes a superior arrangement with quick union rate contrasted and other metaheuristic calculations.Keywords
