Castes and Labor Mobility

How have the poorest sections of society in India responded to the rapid changes in the Indian economy over the past 30 years? We examine this question by contrasting the fortunes of the historically disadvantaged scheduled castes and tribes (SC/ST) in India with the rest of the workforce in terms of their education attainment, occupation choices and wages. We study the period 1983-2005 using household survey data from successive rounds of the National Sample Survey. Our key findings are that education attainment rates and wages have been converging across the two groups while SC/STs have also been switching occupations at increasing rates during this period. Moreover, inter-generational education and income mobility rates of SC/STs have converged to non-SC/ST levels. Clearly, the last twenty years of major structural changes in India have seen a sharp improvement in the relative economic fortunes of these historically disadvantaged social groups. In fact, the median wages of SC/STs relative to non-SC/STs in India have surpassed the median wages of blacks relative to whites in the USA.Intergenerational mobility, wage gaps, castes

Observational constraints on the Emergent Universe with interacting non-linear fluids and its stability analysis

We investigate a flat Emergent Universe (EU) with a nonlinear equation of state which is equivalent to three different compositions of fluids. In the EU, initially, the evolution of the universe began with no interaction, but as time evolves, an interaction sets in among the three fluids leading to the observed universe. The characteristic of an EU is that it is a singularity-free universe that evolves with all the basic features of the early evolution. A given nonlinear equation of state parameter permits a universe with three different fluids. We get a universe with dark energy, cosmic string, and radiation domination to begin with, which at a later epoch transits into a universe with three different fluids with matter domination, dark matter, and dark energy for a given interaction strength among the cosmic fluids. Later the model parameters are constrained using the observed Hubble data and Type Ia Supernova (SnIa) data from the Pantheon data set. The classical stability analysis of the model is performed using the square speed of sound. It is found that a theoretically stable cosmological model can be obtained in this case, however, the model becomes classically unstable at the present epoch when the observational bounds on the model parameters are taken into account.Comment: 16 pages, 9 figure

Enrichment of Lassi by incorporation of peptides from whey protein concentrate

Lassi is a refreshing beverage which is widely consumed throughout our country by people of all age groups. It is a reservoir of nutrients which are easily assimilable by the human body. The current study was initiated to increase functionality of Lassi by incorporation of hydrolyzed whey proteins. A solution of 10% whey protein was hydrolyzed to 7 % degree of hydrolysis (DH) using Flavorzyme at 50 0C for 30 min. using 1:25 enzyme: substrate ratio. Calculated amount of cream and lactic acid were added to the hydrolyzate to bring the desired fat content and pH levels to that of Dahi. It was found that the hydrolyzate could be incorporated at 40 % v/v level in Dahi without causing any adverse effect on the sensory attributes of Lassi. It was found that addition of sugar @15% (w/w) of Lassi gave acceptable quality product. The average composition of optimized product was - 23.04 % TS, 3.78 % protein, 2.33 % fat, 0.49 % ash and 16.5 % total carbohydrates. The average composition of control Lassi was - 22.8 % TS, 1.77 % protein, 2.10% fat, 0.49 % ash and 18.44 % total carbohydrate. The presence of low molecular weight peptides in the optimized product using Tricine SDS-PAGE was confirmed. Enriched Lassi was found to have 79.67 % ACE inhibitory activity as opposed to 42.17 % activity in control sample. It was found that non-thermized enriched Lassi sample had a shelf life of 9 days at 5+2 0C compared to 14 days for thermized sample

Skyrme Fluid in Anisotropic Universes with a Cosmological Constant

Cosmological solutions are obtained in an anisotropic Kantowski-Sachs and Bianchi Type-I universes considering a cosmological constant with Skyrme fluid as a matter source. The solutions in both the KS and Bianchi-I universes obtained here are found to differ significantly, specially with some striking difference like Bianchi-I universe admitting only oscillatory solutions for a particular type of matter configuration. Some new and interesting cosmological solutions are obtained due to the Skyrme fluid in the universe. The anisotropy parameter with the evolution of the universe for both the cases are determined and plotted for comparative study.Comment: The analysis is incomplete and vast change is being done which will reflect major modifications in our obtained result
