Mathematical Modeling of CTLs Dynamics in HIV Antiretro Viral Therapy Interms of Lotka-Volterra Model | Chapter 13 | Science and Technology: Recent Updates and Future Prospects Vol. 11

 

The CTLs dynamics associated with antiretroviral therapy for HIV infection is mathematically modeled as Lotka-Volteterra two species food chain model. Using Painleve property analysis confirmed the stable deterministic nonlinear oscillation dynamics of CTLs. The analogy of Lotka-Volterra system and LCR electrical network system is used to confirm the stability of CTLs oscillation dynamics and found mathematical expression for the radial frequency of that oscillation and its depends on proliferation rate of CD4+T cells. Results are compared with earlier studies. It is found that Antiretroviral therapy with a combination drugs and IL-7 has very little chance of stopping the oscillation of CTL dynamics due to very high nonlinear stability of the dynamics.

Water Quality of Ikop Lake and Its Peripheral Fish Farms of Manipur, India: A Comparative Assessment | Chapter 9 | Research Advances in Environment, Geography and Earth Science Vol. 9

 

The present work explores a comparative valuation of the water quality of Ikop Lake which is a freshwater lake of Manipur, India, and its peripheral fish farms. The water quality of the lake and its peripheral fish farms were assessed by examining fifteen different physicochemical parameters for four months, from June to September 2022. The values of the physicochemical parameters of Ikop Lake and its peripheral fish farm show that 33% of the parameters were not statistically different from WHO recommended value and 66% of the parameters (pH, Temperature, COD, T. Hardness, T. Alkalinity, Chloride, Sodium, potassium, Phosphate, and Total coliform) were exceeded from the standard recommended values. Comparison between the values of the absolute t-score of the parameters of Ikop Lake and its peripheral fish farms shows that the farm's water quality is more degraded than lake water.

Solution of Fractional Differential Equation of Variable Order via S-Iteration | Chapter 6 | Research and Applications Towards Mathematics and Computer Science Vol. 3

 The present phase studies the solvability of the initial profit problem for the variable-order partial differential equating (FDE) involving the Caputo fractional derivative in Banach room. The existence and differentness of the solution of FDE is intentional using the application of the S-redundancy method. Since the study of concerning qualities not quantities properties usually demands the use of differential and basic inequalities, the S-redundancy method contributes evenly to the study of various possessions such as reliance on initial data, the nearness of solutions, and reliance on parameters and functions involved in the kindliness the FDE. Finally, we illustrate our main result through an model.

Terminalia catappa as a Novel Biosorbent for the Removal of Divalent ion from Aqueous Solutions: Experimental Investigation | Chapter 9 | Novel Aspects on Chemistry and Biochemistry Vol. 1

 A spiroborate ester of curcumin (CBS) was combined using salicylic acid as a ligand to study the movement of its warm and hydrolytic degradation. The construction of the prepared compound was from UV-Visible spectra, IR spectroscopy, and NMR spectroscopy. The isothermal and non-isothermal thermogravimetric order was used to study the thermal breakdown of CBS at various heating rates in a nitrogen air. The hydrolytic stability of the spiroborate ester was examined in an aqueous acetone order with various water percentages and temperatures. The incitement energies of hydrolysis were premeditated using the Arrhenius equating, and the relevant thermodynamic limits were calculated utilizing the Eyring equation. A reasonable mechanistic route for the hydrolysis of the complex was suggested.

Determining the Main Provisions of М. Faraday’s Work and Development of Innovative Technologies | Chapter 5 | Current Advances in Chemistry and Biochemistry Vol. 10

 M. Faraday's work began to play a pivotal role in the evolution of theories about chemical bonds and the practical application of electrochemical processes. In the twentieth century, a vast amount of experimental data has amassed, confirming M. Faraday's beliefs on the effect of electric current on chemical reactions. M. Faraday's Key Abstracts:

• The distinct nature of electric current;
• The identity of energy expressions in the interaction of material objects.

The concept of the discrete character of the electric current allows for the organisation of novel chemical reactions by combining parameters and shape of the electric current signal. The scientific provisions on the process of heat exchange (and, in general, energy exchange) between material objects must be revised, as evidenced by the provision on the identification of energy manifestations in the interaction of material objects. A large amount of experimental data was amassed in the twentieth century, showing the practical importance of M. Faraday's beliefs on the effects of electric current on chemical reactions [1-5].

It's worth noting that boosting research money isn't the only way to promote sustainable development. Countries with well-developed scientific infrastructure actively organise the participation in research of talented scientists from all around the world — scientific research globalisation. These organisational patterns of study in key research domains point to attempts to solve problems through "attack." Naturally, this results in exorbitant human labour expenditures and inflated financial prices. So, what's the best way to convey this situation? The reason for this is that natural science is undergoing a crisis. Surprisingly, the increase in the number of experimental data, which is considered aberrant by prevailing concepts, generates an increase in attention to the experimental solution of genuine problems. The necessity to change existing theoretical ideas on chemical, physico-chemical, and other energy processes in diverse technologies is dictated by the evaluation of "anomalous" experimental evidence and extreme natural phenomena.

It is possible to formulate the concept of "energy" based on these provisions, to determine the mechanism of heat transfer between material objects, to clarify the transport properties of physical and chemical systems, and to determine the energy transfer between material objects when they move relative to each other.

Discussion on Formula of Thermogradient Effect | Chapter 4 | Recent Developments in Engineering Research Vol.4

 

This current paper attempts for formulation of empiric formula, which establishes relations between
major matrix parameters of ceramic materials and composites and the coefficient of resistance to
material thermogradient. It has been proved that work-pieces reveal maximum thermal resistance and
preservation of exploitation properties, when total closed porosity is within 2% - 8%, and pore sizes
vary within 1 - 6 mcm. Besides, they are more or less of spherical form and are spread equally in the
matrix. Thermo-gradient effect formula was defined for complex form work-pieces, when surfaces in
the pieces are transacted several times by angles of various curvature radii.
