Chemical graph theory has an important impact on the development of the chemical sciences. A chemical graph is a graph that is produced from some molecular structure by applying some graphical operations. The demonstration of chemical compounds and chemical networks with the M-polynomials is a revolution and the M-polynomial of different molecular structures contributes to evaluating many topological indices. In this paper we worked out M-Polynomial and topological indices of the tadpole graph, then we recovered numerous topological indices using the M-polynomials.

Density functional theory (DFT) calculations were performed to investigate a nanocarbon-assisted biosensor for diagnosis of exhaled biomarkers of lung cancer. To this aim, an oxidized model of C20 fullerene (OC) was chosen as the surface for adsorbing each of five remarkable volatile organic compounds (VOC) biomarkers including hydrogen cyanide, methanol, methyl cyanide, isoprene, and 1-propanol designated by B1-B5. Geometries of the models were first optimized to achieve the minimum energy structures to be involved in further optimization of B@OC bi-molecular complexes. The relaxation of B counterparts at the surface of OC provided insightful information for capability of the investigated system for possible diagnosis of such biomarkers. In this case, B1 was placed at the highest rank of adsorption to make the strongest B1@OC complex among others whereas the weakest complex was seen for B4@OC complex. The achievement was very much important for differential detection of each of VOC biomarkers by the investigated OC nanocarbon. Moreover, the recorded infrared spectra indicated that the complexes could be very well recognized in complex forms and also among other complexes. As a final remark, such proposed nanocarbon-assisted biosensor could work for diagnosis of remarkable VOC biomarkers of lung cancer.

This study addressed the issue of lack of understanding of internal marketing orientation in Small Fiancé Banks of India. The purpose of the study was to explain the internal marketing orientation and its consequences in Small Finance Banks (SFBs). A purposive sampling technique was used to select an SFB as single case for the study. The findings of the study confirmed that Internal Marketing Orientation (IMO) has positive bearing on Internal Aspects of Performance (IAP) in SFB and IMO has a positive influence on both External Aspects of Performance (EAP) and External Marketing Orientation (EMO).

This study focuses on obtaining an extract from clove and calendula plants with colloidal nanoparticles of silver in the presence of 40% propyleneglycol and preparation of hydrophilic gel based on the resulting extract. Also, the optimal composition of the gel and releasing of biologically active substances from gels based on chitosan, sodium carboxymethylcellulose, carbopol, used as gelling agents was evaluated. The results showed that the release of bioactive compounds from a chitosan-based gel is more complete and intensive. The antibacterial and antifungal properties of chitosan gel containing silver nanoparticles have been confirmed by microbiological studies.

Algebraic polynomials play an important role in theoretical chemistry because these can reflect the properties of the chemical compound. M-polynomial is also an algebraic polynomial that is used to find the expressions of several degree dependent topological indices. These topological indices have the ability to explore the information store in the chemical molecule. In this work, we computed the M-polynomial and then obtained the degree-based topological indices for the benzene ring embedded in P-type-surface in 2D network. We also explored the results graphically.

Conductance of 6-(4-chlorophenyl)-1, 2, 3, 4-tetrahydro-2,4-dioxopyrimidine-5-carbonitrile has been measured in 60% dimethyl sulphoxide-water mixture at different concentrations from 298 to 313 K. Limiting molar conductance (λ0m), degree of dissociation (α), dissociation constant (Kd), Walden constant, energy of activation and thermodynamic parameters are calculated. The results obtained are useful for determining the interactions and solvent properties.

< p>The article is devoted to the study of the leaves of the fig (Ficus carica L.) tree is one of the most valuable trees of the Absheron Peninsula (Azerbaijan). Research on fig leaves growing in Mardakan and Nardaran areas of Absheron has been carried out on EPR spectrometer. Studies have shown that stressors cause the formation of nanophase particles of biogenic origin in living systems. These nanoparticles lead to the formation of magnetic properties in biological systems and the formation of the broad EPR signal that we first discovered in plants. It was found that the magnetic properties depend on the type of plant and the environmental conditions in which they live and the characteristics of EPR signals characterizing magnetic nanoparticles (amplitude, signal width, g factor, etc.) are strongly dependent on temperature and that this signal has magnetic anisotropy. Studies of fig leaves have shown that as a result of biomineralization under stress, they form magnetic nanoparticles of iron oxide. In addition, the high intensity of the broad EPR signal characteristic of nanophase magnetic particles detected in fig leaves growing in Mardakan area (Azerbaijan) indicates that the plant system in this area is more exposed to pollutants and the area is more environmentally polluted than Nardaran Area (Azerbaijan). The characteristic verve phase transition occurs at a temperature of 120-125 K in the behavior of parameters such as the amplitude of the magnetic resonance signal and the width of the magnetic resonance line. The results were confirmed by the messabauer method.

Polysaccharides have multiple significant roles and possess extensive bioactivities in field of medicine, healthcare, food and cosmetic industries, because of their therapeutic effects and relatively minimal toxicity. For the first time, we investigated the chemical structure of Ziziphus spina Christ fruits polysaccharides fraction. The plant is classified as one of the most important Sudanese medical plant, still not adequately researched. The Z. spina Christi polysaccharides fraction was extracted by using cold water extraction method, deproteinized via Savage’s method, then after participated by using ethanol 80%, the precipitant fractions were dried via lyophilized for 24h. ZSCFPs was investigated by using colorimetric and analytic methods; the colorimetric assays were carried out to determine some functional groups in the polysaccharides fraction such as phenol-sulfuric acid, sulfuric acid - carbazole reaction, ferric chloride reaction. The analytical assays were carried out to confirm the chemical structure of the ZSCFP 80%, which were FTIR spectra, Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), and X-ray diffraction (XRD).
