<P>Turfgrasses are environmentally and recreationally valuable plants that are constantly subjected to various forms of stress in their artificial and natural habitats. Previously, it was shown that the transformation of a hyperactive mutant (Serine 599 Alanine, S599A) of oat phytochrome A in zoysia grass (Zoysia japonica) and creeping bentgrass (Agrostis stolonifera L.) resulted in superior quality turfgrass with improved shade tolerance response. We now examined the abiotic stress response of the transgenic turfgrasses expressing the hyperactive mutant S599A-PhyA. The transgenic S599A-PhyA plants subjected to high salinity and heavy metal toxicity stress exhibited higher chlorophyll content, lower hydrogen peroxide level, and higher proline accumulation than the controls. Furthermore, the anti-oxidative activities of four reactive oxygen species scavenging enzymes and the total biomass (above and below-ground) were higher in S599A-PhyA plants than in the controls under both the stress conditions. Moreover, higher photosynthetic efficiency (F-v/F-m) of S599A-PhyA plants indicated healthier growth than the controls under stress conditions. Results suggest that the hyperactive mutant of oat phytochrome A confers abiotic stress tolerance in plants, and can be used to efficiently develop abiotic stress tolerant crops in future.</P>

Total Cross Sections for Neutron Nucleus Scattering
S. V. Suryanarayana,H. Naik,S. Ganesan,S. Kailas,R. K. Choudhury,김귀년 한국물리학회 2011 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.59 No.23
Ramsauer model is well known and widely applied to understand systematics of neutron nucleus total cross sections. In this work, we examined the role of nuclear effective radius parameter (r_0) on Ramsauer model fits of neutron total cross sections. We examined the Ramsauer model global analysis of the experimental neutron total cross sections reported by W. P. Abfalterer, F. B. Bateman, et. al., from 20 MeV to 550 MeV for nuclei ranging from Be to U. The global fits predict within ±8% deviation to data.It has been observed that a finer adjustment of r_0 parameter alone can give very good Ramsauer model description of neutron total scattering data within ±4% deviation. The required r_0 values for Ramsauer model fits are provided as a function of nuclear mass number. In optical model study, we have modified the real part of Koning-Deleroche potentials to fit the neutron total cross sections using SCAT2 code. The modified potentials have a different energy dependence beyond 200 MeV of neutron energy and fit the neutron total cross sections from C to Bi.
Comparative Study on the Nutritional Value of Pidan and Salted Duck Egg
Ganesan, P.,Kaewmanee, T.,Benjakul, S.,Baharin, B.S. Korean Society for Food Science of Animal Resource 2014 한국축산식품학회지 Vol.34 No.1
Pidan and salted duck eggs are of nutritional rich alternative duck egg products which are predominantly consumed in China, Thailand, South Korea and other Chinese migrated countries. Both eggs are rich in proteins, lipids, unsaturated fatty acids and minerals. A Pidan whole egg contains 13.1% of protein, 10.7% of fat, 2.25% of carbohydrate and 2.3% of ash, whereas the salted duck egg contains 14% of protein, 16.6% of fat, 4.1% of carbohydrate and 7.5% of ash. The fresh duck egg contains a range of 9.30-11.80% of protein, 11.40-13.52% of fat, 1.50-1.74% of sugar and 1.10-1.17% of ash. Proteins, lipids, and ash contents are found to be greatly enhanced during the pickling and salting process of pidan and salted duck eggs. However, the alkaline induced aggregation of pidan leads to degradation and subsequent generation of free peptides and amino acids. Very few amino acids are found to be lost during the pickling and storage. However, no such losses of amino acids are reported in salted duck eggs during the salting process of 14 d. Phospholipids and cholesterol contents are lower in pidan oil and salted duck egg yolk oil. Thus, the pidan and salted duck eggs are nutritionally rich alternatives of duck egg products which will benefit the human health during consumption.

<P>Abstract. We present a hierarchical Bayesian method for atmospheric trace gas inversions. This method is used to estimate emissions of trace gases as well as 'hyper-parameters' that characterize the probability density functions (PDFs) of the a priori emissions and model-measurement covariances. By exploring the space of 'uncertainties in uncertainties', we show that the hierarchical method results in a more complete estimation of emissions and their uncertainties than traditional Bayesian inversions, which rely heavily on expert judgment. We present an analysis that shows the effect of including hyper-parameters, which are themselves informed by the data, and show that this method can serve to reduce the effect of errors in assumptions made about the a priori emissions and model-measurement uncertainties. We then apply this method to the estimation of sulfur hexafluoride (SF6) emissions over 2012 for the regions surrounding four Advanced Global Atmospheric Gases Experiment (AGAGE) stations. We find that improper accounting of model representation uncertainties, in particular, can lead to the derivation of emissions and associated uncertainties that are unrealistic and show that those derived using the hierarchical method are likely to be more representative of the true uncertainties in the system. We demonstrate through this SF6 case study that this method is less sensitive to outliers in the data and to subjective assumptions about a priori emissions and model-measurement uncertainties than traditional methods. </P>

<P>The present study reports on a novel polymer blend electrolyte system comprised of poly(ethylene oxide), poly (vinylidene fluoride) and poly (methyl methacrylate) (PEO/PVdF/PMMA) with potassium iodide, iodine and novel and cost effective organic compounds such as 1-(2-(2-(2-(2-(benzoate)ethoxy)ethoxy)ethoxy)ethoxy) benzene (BEB) and 1-(2-(2-(2-(2-(1}1-pyrazol-1-yl)ethoxy)ethoxy)ethoxy)ethyl)-1H-pyrazole (PEP) for dye-sensitized solar cell applications. The influence of the synthesized organic compounds on the ionic and photovoltaic characteristics of the electrolytes was studied. In specific, the PEO/INdF/PMMA/ICVI2/PEP blend electrolyte exhibited high ionic conductivity of 6.3 x 10(-4) S cm(-1) and the corresponding DSSC demonstrated an enhanced conversion efficiency of 9%. The high photovoltaic conversion efficiency of the cell with the PEP-doped system can be attributed to the higher conductivities in the polymer electrolyte associated with the greater cross-linking and the increased I-/I-3(-) transportation along the interaction of the tetra ethylene glycol derivative, salt and the polymer matrix.</P>
Vibration and stability of fluid conveying pipes with stochastic parameters
Ganesan, R.,Ramu, S. Anantha Techno-Press 1995 Structural Engineering and Mechanics, An Int'l Jou Vol.3 No.4
Flexible cantilever pipes conveying fluids with high velocity are analysed for their dynamic response and stability behaviour. The Young's modulus and mass per unit length of the pipe material have a stochastic distribution. The stochastic fields, that model the fluctuations of Young's modulus and mass density are characterized through their respective means, variances and autocorrelation functions or their equivalent power spectral density functions. The stochastic non self-adjoint partial differential equation is solved for the moments of characteristic values, by treating the point fluctuations to be stochastic perturbations. The second-order statistics of vibration frequencies and mode shapes are obtained. The critical flow velocity is first evaluated using the averaged eigenvalue equation. Through the eigenvalue equation, the statistics of vibration frequencies are transformed to yield critical flow velocity statistics. Expressions for the bounds of eigenvalues are obtained, which in turn yield the corresponding bounds for critical flow velocities.
Multi Area Power Dispatch using Black Widow Optimization Algorithm
Girishkumar, G.,Ganesan, S.,Jayakumar, N.,Subramanian, S. International Journal of Computer ScienceNetwork S 2022 International journal of computer science and netw Vol.22 No.10
Sophisticated automation-based electronics world, more electrical and electronic devices are being used by people from different regions across the universe. Different manufacturers and vendors develop and market a wide variety of power generation and utilization devices under different operating parameters and conditions. People use a variety of appliances which use electrical energy as power source. These appliances or gadgets utilize the generated energy in different ratios. Night time the utilization will be less when compared with day time utilization of power. In industrial areas especially mechanical industries or Heavy machinery usage regions power utilization will be a diverse at different time intervals and it vary dynamically. This always causes a fluctuation in the grid lines because of the random and intermittent use of these apparatus while the power generating apparatus is made to operate to provide a steady output. Hence it necessitates designing and developing a method to optimize the power generated and the power utilized. Lot of methodologies has been proposed in the recent years for effective optimization and economical load dispatch. One such technique based on intelligent and evolutionary based is Black Widow Optimization BWO. To enhance the optimization level BWO is hybridized. In this research BWO based optimize the load for multi area is proposed to optimize the cost function. A three type of system was compared for economic loads of 16, 40, and 120 units. In this research work, BWO is used to improve the convergence rate and is proven statistically best in comparison to other algorithms such as HSLSO, CGBABC, SFS, ISFS. Also, BWO algorithm best optimize the cost parameter so that dynamically the load and the cost can be controlled simultaneously and hence effectively the generated power is maximum utilized at different time intervals with different load capacity in different regions of utilization.
