Abstract

Abutilon indicum (Linn) sweet (Malvaceae) is a weed found on way side and at west place throughout the India, commonly known as Atibala. Phytochemical study of the plant revealed that the plant contains various phytoconstituent like flavonoids, tannins and phenolic compounds. Plant may give antioxidant activity as these phytoconstituents are reported to have antioxidant potential. Antioxidant activity of the various extracts of the aerial parts of A. indicum viz. petroleum ether extract, chloroform extract, methanol extract and aqueous extract was evaluated by using DPPH assay method, ABTS assay method and FRAP assay method. Total phenolic content of all the extracts was also determined. Results showed that methanol extract shows potent antioxidant activity and highest phenolic content.

Abstract

The possibility of using the electrochemically synthesized poly(o-anisidine) (POA) coatings on low carbon steel (LCS) for corrosion protection purposes was examined under different pH condition. The POA coatings were synthesized from an aqueous solution of oxalic acid under cyclic voltammetry. The extent of the corrosion protection offered by these coatings to LCS in aqueous 3% NaCl was examined by potentiodynamic polarization technique. The potentiodynamic polarization measurements demonstrate that the POA acts as a protective layer on LCS against corrosion in chloride solution. The porosity in the coating was estimated by using the potentiodynamic polarization data and it is observed that the porosity depends on the pH condition used for the synthesis of the POA coatings. The protection of low carbon steel against corrosion in 3% NaCl by the POA coatings can be achieved more effectively when the synthesis was carried out in electropolymerization solution of pH 7.0. This study shows that a POA coating be considered as a potential coating material to protect LCS against corrosion in a chloride environment.

Abstract

Sugarcane is a very useful industrial crop grown in India for its economic importance and various applications of products and byproduct to industry. It has a wide range of genetic diversity which provides a tremendous scope for genetic improvement of economic traits. An improvement in cane yield and quality characters in sugarcane crop is normally achieved by selecting the genotypes with desirable character combinations existing in nature or by hybridization. Hence, the information in a collection of some genotypes of sugarcane in order to formulate a sound breeding plan for its improvement has been reviewed here.

Keywords

Sugarcane, Variability, Correlation, Path Analysis, Genetic Divegence.

Abstract

This research study highlights two main objectives, first is selection of best suited material for gearbox housing and second objective is selection of number of connecting bolts to eliminate the excitation and heavy vibration. Heavy vehicle medium duty truck transmission gearbox housing is subjected to harmonic and internal excitations which are the main source of noise and vibration. Noise and vibration harness is required to increase the performance of transmission gearbox. Gearbox housing materials should have damping nature to sustain the vibration and minimised the gear damage by reducing the amplitude of vibration. To select best suited material Young's modulus was selected as design parameter. To prevent the excitation and heavy vibration gearbox housing is tightly mounted on vehicle frame using connecting bolts. To find the optimized number of connecting bolts Response Surface Method (RSM) was used. Design parameters are number of connecting bolts and housing material property (Young's modulus). The output response is frequency (Hz) and detuning principle was used to find the safe condition for gearbox housing. Results of this research study have been validated with available literature results. Ansys version 14.5 was used for FEA analysis and solid edge, Pro-E for solid 3D modelling.
