Domination topological properties of some chemical structures using φp-polynomial approach
Volume 3, Issue 4 , April 2021, Pages 210-218
Abstract
φp -Polynomial is one way to represent a graph algebraically, and it has a major role in theoretical chemistry. It is used in the calculation of the exact values of many topological ... Read More
On the ψk-polynomial of graph
Volume 3, Issue 4 , April 2021, Pages 219-226
Abstract
In this paper, for every k-degree distance we define ψk-Polynomial of a connected graph G=(V,E) as where ψk(i,j) is the number of edges uv in G such that {dk(v), dk(u)}={i,j} ... Read More
Using new surfactants in EOR process for new cases to lower the oil water interfacial tension
Volume 3, Issue 4 , April 2021, Pages 227-232
Abstract
In summary, NPs help in reducing the IFT either alone or in combination with surfactants. Moreover, NPs can also reduce the adsorption of surfactants on reservoir rock surface. However, ... Read More
Effects of graphene oxide (GO) nanoparticle and SDS on storage capacity of CO2 in hydrate
Volume 3, Issue 4 , April 2021, Pages 233-243
Abstract
In this study, the effect of nanoparticle of graphene oxide and surfactant sodium dodecyl sulfate (sds) 400 ppm on the storage capacity of co2 in hydrate was investigated. A laboratory ... Read More
Phytochemical screening by using GC-MS and FTIR spectrum analysis of fixed oil from Sudanese Ziziphus spina Christi seeds
Volume 3, Issue 4 , April 2021, Pages 244-256
Abstract
The current trend of using natural products from the plants, either as pure constituents or as standardized extracts, provides numerous opportunities for novel drugs, precisely the ... Read More
On the ABC and GA indices of the corona products of some graphs
Volume 3, Issue 4 , April 2021, Pages 257-263
Abstract
In this research, we derived the formulae for the atom-bond connectivity (ABC) index and the geometric-arithmetic (GA) index of several corona products of graphs made by composing the ... Read More
Comparing loosening between cement retained and screw retained implant supported crowns: a dynamic non-linear finite element analysis
Volume 3, Issue 4 , April 2021, Pages 264-277
Abstract
Titanium root form implants are widely accepted because of the advantages of their mechanical properties. This study compared the screw loosening between two types of implant supported ... Read More
