The objective was to determine the reliability and feasibility of Community Balance and Mobility Scale (CB&MS) as a screening instrument for identifying balance dysfunction in elderly population in an Indian situation. An observational study was conducted in community and old age homes residing elderly population, involving 33 elderly individuals aged 60 years and above, selected by convenience sampling method. CB&MS and Computerized Static Posturography measures were used for assessment. Intraclass Correlation Coefficient and spearman's correlation coefficient were used for analysis. Results showed high test-retest reliability (0.985) but no correlation with velocity moment measure of Computerized Static Posturography. Our findings demonstrated that CB&MS is reliable and feasible and hence could be applicable in the community for assessing balance and mobility of young old elderly population.Keywords

The chiral materials are composed of the chiral molecules or inclusions which have ability to rotate electromagnetic waves or polarized light to a desired angle depending on chirality or handedness of the molecule or inclusions and the length of the medium. Fluids like sugar solution, sugar cane juice, turpentine and most of the body fluids etc are chiral. In recent years considerable attention has been given on the study of effect of chirality of molecules or inclusions on the propagation of electromagnetic waves through chiral medium, fabrication of chiral bio-interface materials, synthesis of chiral drug and chiral polymers. In this regard, present paper is intended to study the flow response of chiral fluid flowing in a vertical channel bounded by rigid permeable boundaries in the presence of applied transverse magnetic field under the influence of viscous dissipation, and convection electric current. The simplified and generalised non-linear momentum and energy equations governing the flow of a chiral fluid confined in a channel are solved for velocity and temperature for various values of dimensionless parameter analytically using the regular perturbation method with buoyancy parameter ‘N’ as perturbation parameter and numerically using finite difference method with Successive Over Relaxation (SOR) technique. The results obtained are depicted graphically and found that the resistance to flow of chiral fluid decreases with increase in the transverse magnetic field and the flow reversal occurs with change in the chirality parameter γ from -1 to 1Keywords

The simultaneous delivery of water and fertilizers to the active ischolar_main zone through subsurface drip fertigation system ensures optimum growth of sugarcane. Field experimentwas conducted at ZARS, V.C. Farm,Mandya during 2014-15 and 2015-16 seasons comprising of plant and ratoon cane, respectively. The investigation was conducted to know the performance of sugarcane as influenced by duration and levels of subsurface drip fertigation. Results revealed that fertigation duration upto 9.5 months recorded significantly higher growth parameters of plant and ratoon cane at harvest viz., plant height (330.6 and 296.2 cm), number of tillers m-1 (34.66 and 43.33), leaf area dm2m-1 (87.32 and 118.69), total dry matter production g plant-1 (652.57 and 466.91) and SPAD reading (34.67 and 37.72), respectively. Growth parameters significantly not influenced by fertigation levels. Whereas, the interaction between fertigation duration and levels were significant. Fertigation upto 9.5 months with 125 per cent RDF recorded significantly higher growth parameters viz., plant height (332.5 and 299.5 cm), number of tillers m-1 (34.97 and 43.98), leaf area dm2m-1 (89.27 and 121.63), total dry matter production g plant-1 (658.70 and 473.37) and SPAD reading (34.92 and 37.82) in plant and ratoon cane, respectively at harvest. Stastically, at par results were observed with fertigation upto 9.5 months with 100 per cent of RDF and fertigation upto 9.5 months with 75 per cent of RDF. Normal method of sugarcane cultivation with surface irrigation with 100 per cent RDF soil application recorded lower plant height (281.4 and 259.1 cm), number of tillers m-1 (29.2 and 38.15), leaf area dm2m-1 (57.34 and 84.38), total dry matter production g plant-1 (519.69 and 340.36) and SPAD reading (23.39 and 26.47). Thus, results clearly indicated that 25 per cent of the recommended dose of fertilizer could be saved with higher cane growth through sub surface drip fertigation (SSDF) over normal practice of sugarcane cultivation.Keywords

An experiment studying the effects of various levels of fertigation duration and fertigation levels on jaggery quality parameters of sugarcane using the variety CO86032 over two crop seasons (2014-15 and 2015-16) was conducted at ZARS, V.C. Farm, Mandya. Results revealed that jaggery quality parameters like juice extraction per cent, net rendament value, reducing sugars in jaggery and jaggery hardness did not differ significantly due to fertigation duration, fertigation levels and their interaction. Whereas, significantly higher jaggery recovery (13.82 and 13.45%) and jaggery yield (31.92 and 28.19 t ha-1) was recorded with fertigation duration upto 9.5 months in plant and ratoon cane at harvest, respectively. Jaggery recovery and jaggery yield significantly not influenced by fertigation levels. The interaction between fertigation duration and levels were significant. Fertigation upto 9.5 months with 125 per cent RDF recorded significantly higher jaggery recovery(13.96 and 13.55%) and jaggery yield (32.21 and 28.91 t ha-1) in plant and ratoon cane at harvest, respectively. Stastically, at par results were observed with fertigation upto 9.5 months with 100 per cent of RDF and fertigation upto 9.5 months with 75 per cent of RDF. Normal method of sugarcane cultivation with surface irrigation with 100 per cent of RDF soil application recorded lower jaggery recovery (11.87 and 11.10%) and jaggery yield (16.70 and 13.70 t ha-1) of plant and ratoon cane at harvest, respectively. Experimental results clearly indicated that sub surface drip fertigation (SSDF) helps to increase the jaggery quality parameters over normal practice of sugarcane cultivation.Keywords
