Potential of Jerusalem Artichoke Stem for Cellulose Production

Eurasian Chemico-Technological Journal, 2019
There is a potential opportunity to convert almost any type of biomass into biofuel and bio- nanomaterials, if the appropriate biotechnological and chemical processing methods are used. The preference for this or that bioresource is due to the stability

In biology, solving a problem coming to a differential equation in the maple program [PDF]

E3S Web of Conferences
We know that not only the problems of mathematics, but also the mathematical model of a number of processes that occur in nature can been reduced to a differential equation. Most of the quantities found in nature have their own laws.

Solvability and construction of solutions of integral equations

Вестник КазНУ. Серия математика, механика, информатика, 2017
A class of integral equations with respect to one variable function as well as to multivariable function that are solvable for any right hand side of an equation has been singled out. A necessary and sufficient condition for existence of a solution has

The General Solution to a System of Tensor Equations over the Split Quaternion Algebra with Applications

Mathematics
This paper presents a systematic investigation into the solvability and the general solution of a tensor equation system within the split quaternion algebra framework. As an extension of classical quaternions with distinctive pseudo-Euclidean properties,

An Investigation on Mathematical Modeling of Operators on The Hilbert Domain subjected to The Equality Theory

Journal of Applied Science and Engineering
This work begins by presenting the essential and enough circumstances for the presence of the Hermitian solution to equations ΨXΦ + Φ∗YΨ∗ = Ω = Ψ∗XΦ∗+ ΦYΨ in the case where the operators are linear and bounded in a Hilbert space and in terms of the Moore-

About Some Properties of Degenerate Systems of Linear Integro-Differential Equations. I

Известия Иркутского государственного университета: Серия "Математика", 2015
This paper contains the linear system integro-differential equations (IDE), with an identically degenerate or rectangular matrix at the derivative of the unknown vector functions, including systems with a weak singularity in the kernel.

The general solution of impulsive systems with Riemann-Liouville fractional derivatives

Open Mathematics, 2016
In this paper, we study a kind of fractional differential system with impulsive effect and find the formula of general solution for the impulsive fractional-order system by analysis of the limit case (as impulse tends to zero).

The Existence and Representation of the Solutions to the System of Operator Equations A_iXB_i + C_iYD_i + E_iZF_i = G_i(i = 1, 2)

Axioms
In this paper, we give the necessary and sufficient conditions for the existence of general solutions, self-adjoint solutions, and positive solutions to the system of AiXBi+CiYDi+EiZFi=Gi(i=1,2) under additional conditions.
