Abstract:
Tropospheric ozone is also commonly known as ground-level air pollutants which are produced due to the fast development of the economy and society around the world. In our modern society ozone is considered a substance that touches on our society in many ways. [1] This work aims to use the EVA spectrometer for estimation of the ozone concentration and ozone column density over Pune. It consists of input variables such as relative humidity, temperature, the concentration of ozone, the concentration of nitrogen dioxide, column density of nitrogen dioxide, column density of ozone, air mass factor obtained from routine monitoring, and the data recorded. The preliminary findings show that the meteorology conditions and emission patterns play an important part in influencing the ozone concentration. However, a particular system is appropriate sufficient to evaluation the concentration in spite of any situations. Thus, it can be concluded that the EVA spectrometer is able to give reliable and satisfactory estimations of ozone concentration. [3]

Abstract:
Graph theory is a branch of mathematics where we study about some relations between the objects. So it has many direct applications in real life problems. In Electrical circuit analysis also, different electrical elements are connected in a particular way. So both can be analysed with the help of each other. An electrical circuit can be represented by graph. From graph we can obtain different matrices. These matrices satisfy some matrix equilibrium equations of electrical circuit analysis. From these equations we can find many relatins between currents and voltages of electrical circuits. In our previous paper we analysed currents in a circuit with the help of Thevenin’s theorem and graph theory. In this paper, branch currents of an electrical circuit with unknown resistances and voltage are obtained using network equilibrium equations and then it will be verified by Norton’s theorem.

Abstract:
X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS),is a type of absorption spectroscopy that indicates the feature in the X-ray absorption Spectra (XAS) of condensed matter due to the photo absorption cross section for electronic transitions form an atomic core level to final state in the energy region 50-100 ev above the selected atomic core level ionization energy. The K edge x-ray absorption spectrum of most elements of the periodic table can be performed through full multiple scattering calculations. Then, on the basis of a linear combination of the XANES spectra of reference compounds, the presence of the different phases present inside the materials can be quantified. Here, we show that for nanometer scale metallic clusters, it is not sufficient to consider only the electronic state of the metal of interest to perform a linear combination analysis. In the case of these peculiar materials, special attention has to be paid to different structural parameters, for example, the size and morphology of the cluster, the interatomic distance (taking into account contraction/dilatation processes), and the presence of hetero metallic bonds (in the case of bimetallic clusters). Moreover, this approach is not specific to the metallic state. As a conclusion, the quantitative measurement of the structural parameters coming from EXAFS analysis constitutes an invaluable starting point for the FEFF-PCA simulation. The advantages and limitations of the methods are discussed. Recent advances in extended EXAFS and polarized EXAFS using oriented membranes and single crystals are explained. Developments in theory in understanding the XANES spectra are described. The application of X - ray absorption spectroscopy to the study of the Mn4Ca cluster in Photosystem II is presented.

Abstract:
It's becoming more common for hypergeometric functions to be used in fields such as Statistics. There is an introduction to the q-hypergeometric series, or basic hypergeometric series, in the course notes, as well as some basic summation and transformation findings. An attempt has been made to create equations for basic and polybasic hypergeometric series using a known identity and summation formulae for truncated q-series
