Detoxifying effect of Nelumbo nucifera and Aegle marmelos on hematological parameters of Common Carp (Cyprinus carpio L.)
The objective of this study was to investigate the efficacy of Nelumbo nucifera and Aegle marmelos on common carp exposed to sub-lethal concentrations of combined heavy metals (5 ppm) under laboratory conditions. The fish were treated with Nelumbo nucifera (500 mg/kg bwt) and Aegle marmelos (500 mg/kgbwt) for 30 days as a dietary supplement. The blood biochemical parameters of the fish were evaluated by analyzing the level of red blood cells (RBC), packed cell volume (PCV), hemoglobin concentration, glucose, cholesterol, iron and copper. The findings of the present investigation showed significant increase in hemoglobin (p<0.001), RBC (p<0.01) and PCV (p<0.01) of herbal drug-treated groups compared with metal-exposed fish. Conversely, glucose and cholesterol level in blood of common carp showed significant reduction compared with heavy-metal-exposed groups. All the values measured in Nelumbo nucifera and Aegle marmelos treated fish were restored comparably to control fish. Our results confirmed that Nelumbo nucifera and Aegle marmelos provide a detoxification mechanism for heavy metals in common carp
Characterization of New Bacterial Leaf Blight of Rice Caused by Pantoea stewartii subsp. indologenes in Southern Districts of Tamil Nadu
A survey was conducted in the rice fields of Tirunelveli, Tuticorin, Kanyakumari and Madurai districts of Tamil Nadu during 2016to assess the importance of bacterial leaf blight (BLB) of rice caused by Xanthomonas oryzae pv. oryzae. Bacterial Leaf Blight affected leaf samples showing yellowing symptoms or orange to brown stripes on one or both halves of the leaf blade were collected from seventeen places and maintained as isolates. Upon isolation, symptomatic leaf pieces were surface sterilized and placed in wakimoto semi-synthetic medium. The yellow pigmented, raised and translucent colonies with smooth margin were obtained after incubation at 28°C for 2 days. The biochemical characterization revealed that the bacteria belong to gramnegativefacultative anaerobes with small rods either arranged singly or in chains. Thirteen isolates show positive results in biochemical tests viz.,Gram staining, KOH test, starch hydrolysis, anaerobic growth test, tween 80 hydrolysis test, catalase test, citrate utilizationtest and production of yellow pigment on Yeast Dextrose Chalk agar medium. In virulence test, Isolate 1, Isolate 3 and Isolate 4 were considered virulent as they have caused severe blight symptoms both in TN1 and ADT 43, the susceptible check varieties. Based on 16S rRNA sequence analysis, the causal agent was identified as Pantoea stewartii subsp. indolegenes (Accession No. SUB2733370: MF163273; MF163274; MF16327). The biochemical and molecular analysis revealed that the causal agent was not Xanthomonas oryzae pv oryzae, but a new species of bacteriumnamely Pantoea stewartii subsp. indolegenes. This is the first report of new bacterial leaf blight disease of rice caused by Pantoea stewartii subsp.indologenesin southern districts of Tamil Nadu

Mídias Sociais e Administração Pública: Análise do sentimento social perante a atuação do governo federal brasileiro
Este estudo procurou identificar como a análise de sentimento, baseada em textos extraídos de mídias sociais, pode ser um instrumento de mensuração da opinião pública sobre a atuação do governo de forma a contribuir para a avaliação da administração pública. Trata-se de um estudo aplicado, interdisciplinar, exploratório, qualitativo e quantitativo. Foram revisadas as principais formulações teóricas e conceituais acerca do tema e realizadas demonstrações práticas, utilizando-se uma ferramenta de mineração de opinião que proporcionou precisão satisfatória no processamento de dados. Para fins de demonstração, foram selecionados temas que motivaram a realização da onda de protestos que envolveu milhões de pessoas no Brasil em junho de 2013. Foram coletadas, processadas e analisadas, aproximadamente, 130.000 mensagens postadas no Facebook e no Twitter sobre esses temas em dois períodos distintos. Por meio desta investigação, observou-se que a análise de sentimento pode revelar a opinião polarizada dos cidadãos quanto à atuação do governo

Effect of microwave power irradiation on TiO2 nano-structures and binder free paste screen printed dye sensitized solar cells
Titanium dioxide (TiO2) nanostructures (nanorods and nanoparticles) were prepared using a low-cost microwave irradiation method from a polyol medium of glycerol. Titanium glycerolate and TiO2 powders were obtained in the glycerol medium for the first time with four different power densities (240 W, 480 W, 720 W, 960 W) of irradiation using a domestic microwave oven of 2.45 GHz, to understand the impact of power on morphology tuning. The structural and morphological features of the titanium glycerolate and TiO2 powders were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and Raman spectra analysis. The TiO2 was successfully used in the fabrication of photovoltaic devices and as a proof-of-concept binder free paste was prepared and successfully employed for photo-anode using screen printing on the fluorine-doped tin oxide substrate
Real-time Guidance for Pilot assist Rotorcraft Shipboard Landing using MPPI
Presented at the Georgia Tech Career, Research and Innovation Development Conference (CRIDC), Atlanta, GA.Helicopter or rotorcraft shipboard landing is a very challenging flight operation for pilots owing to the pilot fatigue caused by random ship deck motion, turbulence caused by airwake interactions and degraded visual environments due to sea sprays and poor visibility at night. This poster elaborates on the development and assessment of a real-time guidance module for pilot assisted rotorcraft shipboard landing using Model Predictive Path Integral (MPPI) approach, a stochastic optimal control methodology
