Price Transmission, Volatility and Discovery of Gram in Some Selected Markets in Rajathan State, India

Market integration in many agricultural commodities had been extensively studied for the insight it provides into the functioning of such markets, thus giving valuable information about the dynamics of market adjustment, and whether there exist market imperfection, which may justify government intervention. This study empirically investigated price transmission, volatility and discovery of gram across four wholesale gram markets, viz. Jaipur, Kishangarh, Chomu and Malpura in Rajasthan state of India using Johansen's multivariate cointegration approach, VECM, Granger causality tests, GARCH, EGARCH and ARIMA. Monthly wholesale gram price data spanning from January 2011 to December 2015 sourced from AGMARKNET were used. Multivariate cointegration showed that all the selected gram markets were cointegarted in the long-run, meaning long-run price association among these markets. The degree of market integration observed is consistent with the view that Rajasthan state gram markets are quite competitive; thus, provide little justification for extensive and costly government intervention designed to enhance market efficiency through improve competitiveness. Therefore, in order to sustain the present system of market integration, there is need to evolve mechanism that will generate market information and market intelligence which would serve as a platform for guiding farmers in marketing their produce

Coherent states for polynomial su(1,1) algebra and a conditionally solvable system

In a previous paper [{\it J. Phys. A: Math. Theor.} {\bf 40} (2007) 11105], we constructed a class of coherent states for a polynomially deformed $su(2)$ algebra. In this paper, we first prepare the discrete representations of the nonlinearly deformed $su(1,1)$ algebra. Then we extend the previous procedure to construct a discrete class of coherent states for a polynomial su(1,1) algebra which contains the Barut-Girardello set and the Perelomov set of the SU(1,1) coherent states as special cases. We also construct coherent states for the cubic algebra related to the conditionally solvable radial oscillator problem.Comment: 2 figure

Non-Arrhenius Behavior of Surface Diffusion Near a Phase Transition Boundary

We study the non-Arrhenius behavior of surface diffusion near the second-order phase transition boundary of an adsorbate layer. In contrast to expectations based on macroscopic thermodynamic effects, we show that this behavior can be related to the average microscopic jump rate which in turn is determined by the waiting-time distribution W(t) of single-particle jumps at short times. At long times, W(t) yields a barrier that corresponds to the rate-limiting step in diffusion. The microscopic information in W(t) should be accessible by STM measurements.Comment: 4 pages, Latex with RevTeX macro

First report of cepheid scyphozoan jellyfish Marivagia stellata Galil & Gershwin, 2010 from Palk Bay, southeast coast of India

During a regular survey along the Palk Bay on 25th July 2018, 16 specimens of Marivagia stellata were collected from shore-seine operations at Dhargavalasai in Ramanathapuram District of Tamil Nadu, southeast coast of India. The presence of M. stellata has been reported along the west coast earlier, however, this is the first time the occurrence of this species is reported along the Palk Bay coast of India. M. stellata is relatively a smaller jellyfish species and has been described only in 2010 from the Mediterranean coast of Israel. This species’ sting is not harmful to human

Equilibrium Properties of A Monomer-Monomer Catalytic Reaction on A One-Dimensional Chain

We study the equilibrium properties of a lattice-gas model of an $A + B \to 0$ catalytic reaction on a one-dimensional chain in contact with a reservoir for the particles. The particles of species $A$ and $B$ are in thermal contact with their vapor phases acting as reservoirs, i.e., they may adsorb onto empty lattice sites and may desorb from the lattice. If adsorbed $A$ and $B$ particles appear at neighboring lattice sites they instantaneously react and both desorb. For this model of a catalytic reaction in the adsorption-controlled limit, we derive analytically the expression of the pressure and present exact results for the mean densities of particles and for the compressibilities of the adsorbate as function of the chemical potentials of the two species.Comment: 19 pages, 5 figures, submitted to Phys.

DEVELOPMENT AND EVALUATION OF AN IMPROVED ELECTRO-MECHANICAL YAM POUNDING MACHINE

Yam is one of the oldest known recipes to man, which belongs to the class of carbohydrate and has been a part of the African meals for centuries. Pounded yam is generally accepted food prepared from yam tuber using indigenous method or equipment. Replacing such energy in cooking and yam pounding operation became expedient due to many reasons including tedious, laborious and very difficult. Materials to be used for construction of the electro-mechanical pounding machine were sourced locally and three different varieties of yam were used for its performance evaluation. It was observed from the result that the efficiency of the machine is high [98.75% (white yam), 99.70% (yellow yam), and 99.10% (water yam)]. The percentage lump and pounding capacity for white yam, yellow yam and water yam were 1.25, 3.49, 0.90 and 31.71, 29.68, 27.73g/s respectively

Scyphozoan Jelly fish Diversity in the Gulf of Mannar and Palk bay with an account on the Invasive Jelly fish Phyllorhiza punctata

Swarming dynamics of scyphozoan jelly fishes have great in-fluence on the coastal ecosystem, wherein some scyphozoan are filter feeder and others are piscivores/carnivores. The summer swarming of jellyfishes along the Gulf of Mannar and Palk Bay coast was monitored since 2013 during the months from April to September, and different species of jelly fishes could be recorded in the coastal waters. Furthermore the beach seine operation hauls in several tons of jellyfishes during their operation along this coast, creating a nuisance situation in the fishing operation. Hence the present study was attempted to document the different species of jelly fishes which are found in the coastal waters of Gulf of Mannar and Palk Bay

Multivalued SK-contractions with respect to b-generalized pseudodistances

A new class of multivalued non-self-mappings, called SK-contractions with respect to b-generalized pseudodistances, is introduced and used to investigate the existence of best proximity points by using an appropriate geometric property. Some new fixed point results in b-metric spaces are also obtained. Examples are given to support the usability of our main result
