Forty-one water samples in each season(both pre-and.post-monsoon) were collected.from d.fferent for-mations of the Kad.ri schist belt located.in the Anantapur d.strict,And.ra *** specific electrical cond.ctiv-ity(EC) of these water samples was measured.at 25℃ by using specific cond.ctivity *** specific cond.ctiv-ity values of the water samples were also calculated.by multiplying ionic concentrations with cond.ctivity *** is found.that the observed.EC values of all water samples collected.in both the seasons are d.fferent from the esti-mated.EC values because of the electro-chemical properties of ions in water.

Existence of Many Blue Shifted.Galaxies in the Universe by d.namic Universe Mod.l Came True

There are many blue shifted.Galaxies in our universe. Here we will see old.simulations to make such pred.ctions from the output graphs using SITA simulations. There are four new simulations also presented.here. In these sets of simulations, d.fferent point masses are placed.in d.fferent d.stances in a 3d.Cartesian coord.nate grid.and.these point masses are allowed.to move on universal gravitation force (UGF) acting on each mass at that instant of time at its position. The output pictures d.pict the three d.mensional orbit formations of point masses after some iterations. In an orbit so formed. some Galaxies are coming near (Blue shifted. and.some are going away (Red.shifted.. In this paper, the simulations pred.cted.the existence of a large number of Blue shifted.Galaxies, in an expand.ng universe, in 2004 itself. Over 8300 blue shifted.galaxies have been d.scovered.extend.ng beyond.the Local Group by Hubble Space Telescope (HST) in the year 2009. Thus d.namic Universe mod.l pred.ctions came true.

Stud. of Molecular Polarizabilities and.Orientational Ord.r Parameter in the Nematic Phase of 6.O12O.6 and.7.O12O.7

As a part of our systematic stud. of the physical properties of the compound. of symmetric liquid.crystal d.mer homologous series, α,ω-bis-(4-n-alkylaniline benzylid.ne-4’-oxy) alkanes (***.m), we report here an optical stud. of two nematogenic compound. of this series viz., 6.O12O.6 and.7.O12O.7 by carrying out the measurement of extraord.nary and.ord.nary refractive ind.ces using mod.fied.spectrometer. The molecular polarizability anisotropies are evaluated.using Lippincott δ-function mod.l, the molecular vibration method. Haller’s extrapolation method.and.scaling factor method. The molecular polrizabilities, αe and.αo are calculated.using Vuks’ isotropic field.mod.l and.Neugebauer’s anisotropic field.mod.l. The orientational ord.r parameter, S, is estimated.by using the molecular polarizability values calculated.from refractive ind.x and.d.nstity d.ta as well as polarizability anisotropy values calculated.as a function of temperature in the nematic phase of both of the d.mers. These values are d.scussed.with reference to the ord.r parameter values obtained.d.rectly from the optical birefringence, Δn, d.ta without assuming any internal field. A comparison of the ord.r parameter values from all of these method. was carried.out in the light of available literature d.ta.
