Abstract
. Molecular topology provides a basis for the correlation of physical as well as chemical properties of a certain molecule. Irregularity indices are used as functions in the statistical analysis of the topological properties of certain molecular graphs and complex networks, and hence help us to correlate properties like enthalpy, heats of vaporization, and boiling points etc. with the molecular structure. In this article we are interested in formulating closed forms of imbalance-based irregularity measures of boron nanotubes. These tubes are known as α-boron nanotube, triangular boron nanotubes, and tri-hexagonal boron nanotubes. We also compare our results graphically and come up with the conclusion that alpha boron tubes are the most irregular with respect to most of the irregularity indices.
Highlights
Bacterial contamination in boar semen is inevitable, largely because the routine procedures of semen collection and manipulation are difficult and generally fail to provide controlled and aseptic ejaculate collections [1,2,3]
Previous studies have demonstrated that boar semen was contaminated with certain bacteria such as Escherichia coli and Pseudomonas aeruginosa in more than 80% of the boars [4,5,6,7]
Contamination of boar semen with Gram-negative bacteria has remained a major concern in the swine artificial insemination industry [2,3,5], and its potential consequences with regard to reduced sperm quality have been at the center of attention
Summary
Bacterial contamination in boar semen is inevitable, largely because the routine procedures of semen collection and manipulation are difficult and generally fail to provide controlled and aseptic ejaculate collections [1,2,3]. It has been demonstrated that Gram-negative bacteria are the most prevalent type of pathogenic microorganism that contaminates the semen [4,5,6,7]. Gram-negative bacteria release endotoxins such as lipopolysaccharide (LPS). It has been reported that certain antibiotics or chemicals when added to the semen extender could reduce bacteria-induced damage to the sperm and can possibly inhibit bacterial proliferation [14,15]. These antibiotics or chemicals are not able to clear the LPS released from Gram-negative bacteria during bacteriolysis [16]
