Dependence of the response of a corona-charged aerosol detector (corona CAD) on the concentration and densities of brominated flame retardants and some related substrates was studied. The calibration curves of the substrates did not show linearity and the substrate with a lower density exhibited the stronger response. Regardless of the solvents (chloroform or toluene), and the injected volume o...

Effect of solution conductivity on production of H2O2, H2 and O2 generated by the pulsed corona discharge in water has been investigated. Hydrogen was dominant product of plasmachemical activity of the discharge when its formation significantly increased with increasing solution conductivity. Compared to H2O2 its production rose from ratio of 2:1 at 100 μS/cm up to 5:1 at 500 μS/cm. Possible ro...

In this paper, we investigate the concept of resolving dominating set in a graph. particular, characterize sets join, corona and lexicographic product two graphs determine domination number these graphs.

A graph is said to be cordial if it has 0 - 1 labeling which satisfies particular conditions. In this paper, we construct the corona between paths and second power of fan graphs explain necessary sufficient conditions for construction cordial.

There is currently no explanation of why the corona has the temperature and density it has. We present a model which explains how the dynamics of magnetic reconnection regulates the conditions in the corona. A bifurcation in magnetic reconnection at a critical state enforces an upper bound on the coronal temperature for a given density. We present observational evidence from 107 flares in 37 su...

This study investigates the possibility of corona discharge ionization technique for reduction of fog. For corona discharge ionization a high voltage power supply is designed and developed indigenously. The high output voltage is developed by using isolation transformer, autotransformer, and high voltage neon transformer and it is converted into DC voltage by using Wheatstone bridge circuit and...

In this paper, we introduced new index from the Zagreb family, named as -index is defined sum of degree five all vertices a graph. We derive some different graph operations such that Join, Cartesian product, Composition, Corona Tensor Product, Strong Disjunction, Symmetric difference, join Subdivision vertex are obtained.
