The antibacterial properties of graphene oxide and the anti-cancer effects of TiO2particles play a vital role in the drug delivery system. Mixing these nanoparticles in the blood by considering the complex rheological natured Sutterby model can maximize drug delivery results. A theoretical analysis is made to evaluate the impact of resistive and radiative heat on the graphene oxide (GO), and titanium dioxide (TiO2) suspended Sutterby blood flow through the stenosed artery. A mathematical model is developed and resolved numerically using the Keller-box approach. The Darcy–Forchheimer, heat convection, and hydromagnetic conditions are considered for physical relevance. The outcomes are obtained for nano and hybrid nano cases and explored with tabular and pictorial representations. It is found that the addition of the GO nanoparticles to the blood-TiO2 combination boosts the heat transmission without affecting the wall friction. This minimizes the external pressure on the blood flow.
Diagrid structures are evolved as one of the best structural system for high rise buildings. In this study seismic performance of 36 stories Tube-in-Tube Diagrid Structure with various diagonal slopes is evaluated by Non Linear Static Analysis. Tube-in-Tube diagrid structures are modified Diagrid structures in which gravity core is replaced with Diagrid core. Single tube diagrid structure is also studied for comparison. The structure is pushed gradually proportional to fundamental Mode shape. The analysis results shows that Tube-in-Tube structure possess higher stiffness and Lateral Load resisting capacity. The pushover analysis demonstrates that diagrid core can perform better by hardening the structure. According to analysis results, the Tube-in-Tube diagrid structure shows higher non-linear lateral displacement. It was observed that as the diagrid angle increases the stiffness and lateral load carrying strength decreases.
Nanotechnology assists high-class openings for biomedical purposes, which could impact medicine and health-related challenges. This technology benefits in many aspects, such as nanocarrier for targeted drug delivery, improved medical imaging, treatment of targeted tumors, and vaccination. Laboratory experiments show that with the help of nanoelectronic devices, the current treatment processes are improving effectively. The outstanding antimicrobial and biocompatibility properties of graphene oxide (GO) and aluminium oxide (Al2O3) nanoparticles are helpful in nano-drug delivery and cancer treatment. In this article, a theoretical investigation is made to examine the heat transfer in GO-Al2O3 suspended blood flow through the stenotic artery. The 2D hybrid blood flow has radiative heat, uniform magnetic field, dissipative, and Cattaneo–Christov thermal flux effects. The comparison of Maxwell and Oldroyd-B hybrid nano models is deemed to analyze the viscoelastic nature of the blood. Altered governing equations are resolved by employing the Keller-Box scheme. Comparative results for Maxwell and Oldroyd-B models are obtained and shown graphically. The outcomes of this study show that the flow of GO-Al2O3 suspended blood under the Oldroyd-B model gives an improved heat transmission rate compared with the Maxwell model. Also, drug resistance is low in Oldroyd-B flow. The properties of GO-Al2O3 nanoparticle composition with the Oldroyd-B rheological nature may help drug delivery.
The biomedical applications and antibacterial properties of graphene oxide (GO) nanoparticles help to treat tumors and improve drug delivery results. The 2-D flow of GO-nanoparticles integrated blood flow through cosine character stenosis artery with radiative heat, heat sink/source, and Cattaneo–Christov temperature flux is assumed. The Darcy–Forchhiemer condition and porosity parameter are imposed in momentum equations. The governing equalities and borderline settings are transformed into ODE using similarity transformation and resolved mathematically using the Keller-box scheme. First, the GO-nanolayer concept has been discussed to inspect heat transmission rate and change in energy and exhibited graphically. A comparison of Maxwell, Sutterby, and Oldroyd-B flow models is made and displayed schematically. It is noticed that the thermal performance is raised due to the GO nanolayer. The energy transmission rate is higher in the Oldroyd-B flow compared to the remaining two flow models. The simulation of this study may help understand the mechanism of blood flows through the stenosis artery. Also, this study can be used for advanced research in biomedical, cancer treatment, etc.
