Abstract:
Role of symmetry is very crucial to explain the various properties and behaviour of the elementary particles. Every symmetry are always associated with corresponding conservation law and it can be either discrete or continuous in nature. The symmetries of the standard model associated with the electromagnetic interaction, weak and strong force are described by the groups U(1), SU(2) and SU(3).Fundamental aspect for some of the symmetry like as permutation symmetry, continuous space-time symmetry, discrete symmetry are elaborated here. higher level of symmetry flavour symmetry, super symmetry and SU(5) symmetry for unification is also discuss here. Various cause of symmetry breaking is discussed here. Consequences of the existence of symmetry is that a corresponding conservation law like as conservation of charge, linear momentum, angular momentum, energy, baryon number, lepton number, parity etc. In this research paper elaboration of various conservation law and its consequences is also done in modern context.

Abstract:
In this research paper, we find the analytical and numerical solutions of “Laplace‟s and Poisson‟s differential equations” satisfying the given boundary conditions, using numerical methods. Mainly, we focus on solution of two dimensional differential equations to understand the concept of Finite Difference Method (FDM).

Abstract:
In this article, an attempt has been made to obtain the optimized geometry and calculate the IR and Raman vibration frequencies of 8CB and 8OCB liquid crystals using DFT/B3LYP method with basis set 6-31G(d,p). The molecules selected for the present investigation are quite interesting because they show excellent chemical and thermal stability due to the strong, and unique physical properties of the C–N bond, which contributes to the performance and photonic applications.

Abstract:
A nucleus having an even number of neutrons and protons is called an even-even (EE) nucleus in atomic physics. Approximately 60% of all stable nuclei are bosons, which mean they have an integer spin. Using covariant density functional theory, the ground-state properties of even–even nuclei from Z=10 to Z=20 are extensively investigated. The influence of triaxiality on nuclear binding energy, including the mean-field part and the rotational correlation energy, is investigated. There is a significant amount of triaxial distortion in 38Si, 46S, and 48S. There is a small but significant effect of the triaxial deformation degree of freedom on the a-field part of the nuclear binding energy in the current nuclei. To make matters even more interesting, we demonstrate that phenomenological collective correction helps to better reflect the evolution trend of the N=20 shell gap by decreasing the root mean square of binding energies for 41 nuclei from Ne to Ar by 2.22MeV to 1.60MeV

Abstract:
The field experiment was conducted at Vegetable Research Farm, Kalyanpur of Chandra Shekhar Azad University of Agriculture & Technology, Kanpur, Uttar Pradesh during kharif season of 2019 the response of micronutrients on different quality traits and economics of bitter gourd. The experiment was laid out in a Randomized Block Design (RBD) with three replications. Fourteen different treatments of micronutrients combination were tested against the control. Results of the experiment revealed that application of foliar feeding of mixture of all micronutrients (boric acid @ 100 ppm + zinc sulphate @ 100 ppm + ammonium molybdate @ 50 ppm + copper sulphate @ 100 ppm + ferrous sulphate @ 100 ppm + manganese sulphate @ 100 ppm) (T7) produced significantly highest T.S.S content (5.45 0Brix), Vitamin-C content (64.62mg/100g), Cost of cultivation (53,881.0Rs/ha.), Gross return (1,84,408.0Rs/ha.) Net return (1,30,527.0Rs/ha) and B:C ratio (3.42). Significantly highest zinc content (85 ppm), Iron content (426 ppm) and copper content (22 ppm) were found in fruits with the application of zinc sulphate @ 100 ppm (T2), ferrous sulphate @ 100 ppm (T5) and copper sulphate @ 100 ppm (T4) respectively. The lowest values of quality traits and economics were recorded in control.

Abstract:
Since it was found that the universe expands earlier than originally thought, astronomy & physical science have been flooded with activity. As a result of this finding, we may conclude that our basic ideas about how gravity works at cosmic distances are erroneous. An easy solution to the problem of general relativity is to add a constant to the field equations. For this reason, and others, scientists have looked into several possible explanations for the anomalously low value of the cosmological constant. These include, among other things, the advent of a novel negative-pressure fluid or changes to general relativity. Evidence for cosmic acceleration will be examined in this section. Here are some of the theories that have been proposed to explain this phenomenon, including the cosmological constant and its variations, quantum mechanic variations of essence, mass-variable neutrinos, and general relativity modifications. Methods for testing some of the theories presented in this Paper will be examined in this chapter's concluding section.

Abstract:
The present paper deals with the theory of [0, 1] valued maps defined on a nonempty set X. We have concentrated over the study of two types of functions, viz. tight functions and smooth functions. The notions of lower and upper envelopes of a function  defined on a sublattice K of X I are introduced, and are extensively used to prove several results. Finally it is obtained that every supermodular and smooth from above function can be extended to an inner regular quasi*- measure.
