SHORT-TERM EFFECT OF DISPERSION OF RESIDUAL SLUDGE ON THE SOIL EUCALYPTUS CAMALDULENSIS DEHNH, TIARET (ALGERIA)

Silvicultural upgrading of sewage sludge is an alternative to current solutions. It presents a lower risk of contamination of the human food chain than its use in agriculture. In this context, the use of forest plantations can offer many advantages

Weak solutions for nonlinear fractional differential equations on reflexive Banach spaces

The aim of this paper is to investigate a class of boundary value problem for fractional differential equations involving nonlinear integral conditions. The main tool used in our considerations is the technique associated with measures of weak noncompactness

Existence results for first order impulsive semilinear evolution inclusions

In this paper the concepts of lower mild and upper mild solutions combined with a fixed point theorem for condensing maps and the semigroup theory are used to investigate the existence of mild solutions for first order impulsive semilinear evolution inclusions

Initial boundary value problems for second order impulsive functional differential inclusions

In this paper we investigate the existence of solutions for initial and boundary value problems for second order impulsive functional differential inclusions. We shall rely on a fixed point theorem for contraction multivalued maps due to Covitz and Nadler

Impulsive Partial Hyperbolic Functional Differential Equations of Fractional Order with State-Dependent Delay

MSC 2010: 26A33, 34A37, 34K37, 34K40, 35R11This paper deals with the existence and uniqueness of solutions of two classes of partial impulsive hyperbolic differential equations with fixed time impulses and state-dependent delay involving the Caputo fractional derivative. Our results are obtained upon suitable fixed point theorems

CHRONOLOGICAL STUDY OF THE VEGETATION OF FOREST MASSIF OF SDAMAS

The massif of Sdamas to which our contribution relates is located in West Algeria, it is an integral part of the mountains of Tiaret. The main objective of this work is to quantify the plant diversity of existing plant groups, and to understand the architecture and the structure of the various groups of vegetation by the method of floristic analysis and statistical analysis

Impulsive Fractional Differential Inclusions Involving the Caputo Fractional Derivative

Mathematics Subject Classification: 26A33, 34A37.In this paper, we establish sufficient conditions for the existence of solutions for a class of initial value problem for impulsive fractional differential inclusions involving the Caputo fractional derivative. Both cases of convex and nonconvex valued right-hand side are considered. The topological structure of the set of solutions is also considered

In the present paper, we investigate, using the Picard operator technique, some existence and Ulam type stability results for the Darboux problem associated to some partial fractional order differential inclusions

Global existence and stability for second order functional evolution equations with infinite delay

In this article, the authors give sufficient conditions for existence and attractivity of mild solutions for second order semi-linear functional evolution equation in Banach spaces using Schauder's fixed point theorem. An example is provided to illustrate the result

Nonresonance impulsive higher order functional nonconvex-valued differential inclusions

In this paper, the authors investigate the existence of solutions for nonresonance impulsive higher order functional differential inclusions in Banach spaces with nonconvex valued right hand side. They present two results. In the first one, they rely on a fixed point theorem for contraction multivalued maps due to Covitz and Nadler, and for the second one, they use Schaefer's fixed point theorem combined with lower semi-continuous multivalued operators with decomposable values
