Ethnoveterinary uses of medicinal plants among the Lambani community in Chitradurga district, Karnataka, India

Abstract: Objective To explore and document ethnomedicinal knowledge of various plants used by the Lambani ethnic group in Chitradurga District of Karnataka, Southern India for traditional veterinary purposes. The area is rich in plant wealth; therefore this study has been made to prepare an inventory of indigenous medicinal plants and to bring traditional knowledge on record. Methods In accordance to standardized WHO questionnaires, one hundred fourteen informants — consisting of healers, practitioners, farmers and village headman — were interviewed regarding the medicinal use of the local flora in various tribal villages of Chitradurga District, Karnataka during February 2010 to October 2010. Results Ethno botanical uses of 39 plants belonging to 24 families have been documented in the present study for their interesting therapeutic properties for various veterinary ailments such as lack of appetites, bloat, fever, ephemeral fever, diarrhea, cough, foot and mouth disease etc. Of the plants studied, most were trees and leaves contributed mainly to the plant part used for medical purpose. Conclusions Lambani tribe, who are generally poor and live in remote areas, use ethno veterinary medicine (EVM) for the primary healthcare of their animals. The use of plants reveals their interest in ethnomedicine and further research on these species could lead to the discovery of novel bioactive molecules for efficient management of diseases.

Aerobic biodegradation of Acid Blue-9 dye by Bacillus fermus Isolated from Annona reticulata

Abstract: A dye being reluctant to degradation due to their structural complexity requires a cost-effective and an eco-friendly technique of degradation. Present study, Bacillus fermus isolated from Annona reticulata , gram positive bacteria was employed for the degradation of Acid Blue-9 dye. Minimal salt media consisting of Na 2 HPO 4 , KH 2 PO 4 , NaCl, NH 4 Cl, MgSO 4 with varying concentration of dye and carbon source was used for the study. Among various carbon sources used, sucrose proved to be an efficient carbon source yielding 97% decolorization. Sucrose concentration of 3g/L showed maximum degradation along with 3% v/v of inoculum concentration. The decolorization was confirmed from the results obtained by UV–visible spectrophotometer at 579 nm. The possible biodegradation pathway was obtained from the analysis of Liquid Chromatography–Mass Spectrometry techniques. It was also observed that degraded product was known to induce lesser chromosomal aberrations in comparison to untreated Acid Blue-9.

Stagnation point flow of a MHD dusty fluid towards a stretching sheet with radiation

Abstract: The effect of radiation on the flow near the two-dimensional stagnation point of an incompressible, viscous, electrically conducting dusty fluid towards stretching sheet is analyzed. Rosseland approximation is used to model the radiative heat transfer. Highly non-linear momentum boundary layer equations and thermal boundary layer equations are converted into similarity equations and then solved numerically using Runge Kutta Fehlberg fourth–fifth order method. The thermal results are analyzed for the situation when stretching boundary is prescribed with surface temperature and prescribed with heat flux. Comparison with previously published work is performed and full agreement is obtained. Variation of physical parameters with the ratio of free stream velocity parameter to stretching sheet parameter have been illustrated graphically and in tabular form to depict special features of the solutions.

Citrate-complexation synthesized Ce0.85Gd0.15O2−δ (GDC15) as solid electrolyte for intermediate temperature SOFC

Abstract: A typical Ce0.85Gd0.15O2-delta (CDC15) composition of CeO2-Gd2O3 system is synthesized by modified sol - gel technique known as citrate-complexation. TG-DTA, XRD, FT-IR, Raman, FE-SEM/EDX and ac impedance analysis are carried out for structural and electrical characterization. XRD pattern confirmed the well crystalline cubic fluorite structure of CDC15 after calcining at 873 K. Raman spectral bands at 463, 550 and 600 cm(-1) are also in agreement with these structural features. FE-SEM image shows well-defined grains separated from grain boundary and good densification. Ac impedance studies reveal that GDC15 has oxide ionic conductivity similar to that reported for Ce0.9Gd0.1O2-delta (GDC10) and Ce0.8Gd0.2O2-delta (GDC20). Ionic and electronic transference numbers at 673 K are found to be 0.95 and 0.05, respectively. This indicates the possible application of GDC15 as a potential electrolyte for IT-SOFCs.
