| 1 | Evaluation of wound healing and antimicrobial potentials of Ixora coccinea root extract显示文摘Objective:To evaluate the wound healing and antimicrobial activity of root extracts of Ixora coccinea(I.coccinea).Methods:To investigate the wound healing efficacy of root extract of I.coccinea Linn,five groups of animals were divided each containing six animals.Two wound models including incision and excision wound models were used in this study.The parameters studied were tensile strength on incision wound model and in terms of wound contraction for excision wound model were compared with standard Nitrofurazone(NFZ) ointment(0.2%w/w). Six extracts(ethanol.aqueous,petroleum ether,benzene,chloroform and ethyl acetate ) of I. coccinea were screened for in vitro growth inhibiting activity against different bacterial strains riz. Staphylococcia aureus.Bacillus pumilius,Enterococcus facialis.Escherichia coli,Salmonella typhi and Pseudomonas aeruginosa and fungi Candida albicans and Aspergillus niger were compared with the standard drugs ciprofloxacin and chloramphenicol for antibacterial and griscofulvin for antifungal screening.The serial dilution and cup(or) well plate methods were used for the antimicrobial study and MIC was determined.Results:The ethanolic extract showed significant (P<0.001) wound healing activity when compared to standard drug NFZ with respect to normal control group.Amongst all.ethanolic extract showed highly significant antibacterial activity against all bacterial strains used in this study when compared to standard.The aqueous extract showed moderate significant inhibition against all bacterial strains when compared to standard. All the extracts were shown negligible activity against the fungal strains used in this study. Conclusions:The ethanolic root extract of I.coccinea showed pronounced wound healing and antibacterial activity.The probable reason to heal the wound was that the external application of the extract prevented the microbes to invade through the wound thus the protection of wound occurs against the infection of the various organisms. | Nagaraj Selvaraj Baskar Lakshmanan Papiya Mitra Mazumder Muthukumar Karuppasamy Simon Santosh Jena Ashok Kumar Pattnaik | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，12： | 5 |
| 2 | Coinoculation of bioinoculants improve Acacia auriculiformis seedling growth and quality in a tropical Alfisol soil显示文摘We conducted a study to find out if arbuscular mycorrhizal(AM) fungi(Acaulospora scrobiculata,Scutellospora calospora) and phosphate solubilizing bacteria(PSB, Paenibacillus polymyxa) inoculation either individually or in combinations can improve Acacia auriculiformis seedling growth, uptake of nutrients and quality in a phosphorus deficient tropical Alfisol. The seedlings were assessed for various growth and nutrient uptake parameters after 60 days of treatment. Inoculation with P.polymyxa stimulated mycorrhizal formation. Seedling height, stem girth, taproot length, number of leaves and leaf area, plant dry matter production, nodulation, and nodular dry weight were significantly higher for seedlings that were either dual inoculated or triple inoculated compared to individual inoculation of AM fungi or PSB, and uninoculated seedlings. Dual and triple application of AM fungi and PSB also significantly improved the nutrient contents of shoots and roots and nutrient uptake efficiencies. The calculated seedling quality indexes of the AM fungi and PSB inoculated seedling were 25–208% higher than uninoculated seedlings. These findings show that A.auriculiformis seedlings when dual inoculated or triple inoculated performed better than seedlings inoculated with the microbes individually and compared with uninoculated control seedlings. We conclude that bioinoculation is important for the production of high-quality A.auriculiformis seedlings in tree nurseries for planting in nutrient deficient soils. | Thangavelu Muthukumar Karuthamuthu Udaiyan | 2018 | Journal of Forestry Research2018，29，3： | 4 |
| 3 | Approximate Controllability of Second-Order Neutral Stochastic Differential Equations with Infinite Delay and Poisson Jumps显示文摘The modelling of risky asset by stochastic processes with continuous paths, based on Brownian motions, suffers from several defects. First, the path continuity assumption does not seem reasonable in view of the possibility of sudden price variations(jumps) resulting of market crashes. A solution is to use stochastic processes with jumps, that will account for sudden variations of the asset prices. On the other hand, such jump models are generally based on the Poisson random measure. Many popular economic and financial models described by stochastic differential equations with Poisson jumps. This paper deals with the approximate controllability of a class of second-order neutral stochastic differential equations with infinite delay and Poisson jumps. By using the cosine family of operators, stochastic analysis techniques, a new set of sufficient conditions are derived for the approximate controllability of the above control system. An example is provided to illustrate the obtained theory. | PALANISAMY Muthukumar CHINNATHAMBI Rajivganthi | 2015 | Journal of Systems Engineering and Electronics2015，26，5： | 3 |
| 4 | Implications of seismic pounding on the longitudinal response of multi-span bridges-an analytical perspective显示文摘Seismic pounding between adjacent frames in multiple-frame bridges and girder ends in multi-span simply supported bridges has been commonly observed in several recent earthquakes. The consequences of pounding include damage to piers, abutments, shear keys, bearings and restrainers, and possible collapse of deck spans. This paper investigates pounding in bridges from an analytical perspective. A simplified nonlinear model of a multiple-frame bridge is developed including the effects of inelastic frame action and nonlinear hinge behavior, to study the seismic response to longitudinal ground motion. Pounding is implemented using the contact force-based Kelvin model, as well as the momentum-based stereomechanical approach, Parameter studies are conducted to determine the effects of frame period ratio, column hysteretic behavior, energy dissipation during impact and near source ground motions on the pounding response of the bridge. The results indicate that pounding is most critical for highly out-of-phase frames and is not significant for frame period ratios greater than 0.7. Impact models without energy dissipation overestimate the displacement and acceleration amplifications due to impact, especially for elastic behavior of the frames. Representation of stiffness degradation in bridge columns is essential in capturing the accurate response of pounding frames subjected to far field ground motion. Finally, it is shown that strength degradation and pounding can result in significant damage to the stiffer frames of the bridge when subjected to large acceleration pulses from near field ground motion records. | Reginald DesRoches Susendar Muthukumar | 2004 | Earthquake Engineering and Engineering Vibration2004，3，1： | 3 |
| 5 | Nutrient optimization for plant growth in Aquaponic irrigation using Machine Learning for small training datasets显示文摘With the recent trends in urban agriculture and climate change,there is an emerging need for alternative plant culture techniques where dependence on soil can be eliminated.Hydroponic and aquaponic growth techniques have proven to be viable alternatives,but the lack of efficient and optimal practices for irrigation and nutrient supply limits its applications on a large-scale commercial basis.The main purpose of this research was to develop statistical methods and Machine Learning algorithms to regulate nutrient concentrations in aquaponic irrigation water based on plant needs,for achieving optimal plant growth and promoting broader adoption of aquaponic culture on a commercial scale.One of the key challenges to developing these algorithms is the sparsity of data which requires the use of Bolstered error estimation approaches.In this paper,several linear and non-linear algorithms trained on relatively small datasets using Bolstered error estimation techniques were evaluated,for selecting the best method in making decisions regarding the regulation of nutrients in hydroponic environments.After repeated tests on the dataset,it was decided that Semi-Bolstered Resubstitution Error estimation technique works best in our case using Linear Support Vector Machine as the classifier with the value of penalty parameter set to one.A set of recommended rules have been prescribed as a Decision Support System,using the output of the Machine Learning algorithm,which have been tested against the results of the baseline model.Further,the positive impact of the recommended nutrient concentrationson plant growth in aquaponic environments has been elaborately discussed. | Sambandh Bhusan Dhal Muthukumar Bagavathiannan Ulisses Braga-Neto Stavros Kalafatis | 2022 | Artificial Intelligence in Agriculture2022，，1： | 2 |
