Macroelements versus toxic elements in selected wild edible mushrooms of the Russulacea family from Serbia [PDF]

open access: yesJournal of the Serbian Chemical Society, 2021
Three edible mushrooms of the Russulacea family (Lactarius deliciosus, Lactarius sanguifluus and Lactarius semisanguifluus), most frequently consumed in Serbia, were analyzed using the ICP-OES technique to evaluate the content of K, P, Ca, Mg, Na, Al, As,

On the structure of finite groups associated to regular non-centralizer graphs

open access: yesAIMS Mathematics, 2023
The non-centralizer graph of a finite group $ G $ is the simple graph $ \Upsilon_G $ whose vertices are the elements of $ G $ with two vertices are adjacent if their centralizers are distinct.

Continuous Dependence of the Singular Nonlinear Van der Pol Equation Solutions with Respect to the Boundary Conditions: Elements of p-regularity Theory [PDF]

open access: yesJournal of Dynamics and Differential Equations, 2020
AbstractThis paper studies the problem of the continuous dependence of Van der Pol equation solutions with respect to the boundary conditions. We provide a new approach for the existence of such solutions via p-regularity theory. Several existence theorems about continuous solutions are established.

Regularity and abundance on semigroups of partial transformations with invariant set

open access: yesOpen Mathematics, 2023
Let P(X)P\left(X) be a partial transformation semigroup on a non-empty set XX. For a fixed non-empty subset YY of XX, let PT¯(X,Y)={α∈P(X)∣(domα∩Y)α⊆Y}.\overline{PT}\left(X,Y)=\left\{\alpha \in P\left(X)| \left({\rm{dom}}\hspace{0.33em}\alpha \cap Y ...

Strongly Semiunits and Tri-Regular Elements in Rings [PDF]

open access: yesEurasian Journal of Science and Engineering, 2018
In this paper we study semiunit elements in the group ring Z2G, where G is a cyclic group and we introduce and discuss strongly semiunit elements in Zn, for n=p, 2p, p2 where p is an odd prime.

‎$‎4‎$‎-Regular prime graphs of nonsolvable groups [PDF]

open access: yesInternational Journal of Group Theory, 2020
Let $G$ be a finite group and $\cd(G)$ denote the character degree set for $G$. The prime graph $\DG$ is a simple graph whose vertex set consists of prime divisors of elements in $\cd(G)$, denoted $\rho(G)$.

On the Number ofp-Regular Elements in Finite Simple Groups [PDF]

open access: yesLMS Journal of Computation and Mathematics, 2009
AbstractAp-regular element in a finite group is an element of order not divisible by the prime numberp. We show that for every primepand every finite simple groupS, a fair proportion of elements ofSisp-regular. In particular, we show that the proportion ofp-regular elements in a finite classical simple group (not necessarily of characteristicp) is ...
