Anderson transition in one-dimensional systems with spatial disorder

open access: yes, 2009
A simple Kronig-Penney model for one-dimensional (1D) mesoscopic systems with $\delta $ peak potentials is used to study numerically the influence of a spatial disorder on the conductance fluctuations and distribution at different regimes.

Chemical Variability of the Leaf Essential Oil of Two Subspecies of Juniperus oxycedrus L. From Northwestern Algeria

open access: yesChemistry &Biodiversity, Volume 22, Issue 2, February 2025.
Abstract Thirty‐seven essential oil samples have been isolated from leaves of individual plants of Juniperus oxycedrus (subspecies oxycedrus and macrocarpa) growing wild in Tlemcen and Aïn Témouchent provinces (Northwestern Algeria). Analysis of eight selected oil samples by GC(RI), GC/MS and 13C NMR, allowed the identification of 88 components that ...

On oscillation theorems for differential polynomials

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2009
In this paper, we investigate the relationship between small functions and differential polynomials $g_{f}\left( z\right)=d_{2}f^{^{\prime \prime }} + d_{1}f^{^{\prime }}+d_{0}f$, where $d_{0}\left(z\right), d_{1}\left( z\right), d_{2}\left( z\right ...

Excess paste method to formulate a self-compacting concrete

open access: yesJournal of Building Materials and Structures, 2014
On the basis of the principle that a concrete is composed of a liquid phase (paste) and a solid phase (aggregates with fixed gravel/sand ratio), the concrete self-compacting properties come necessarily from those of the paste.

Chemical Variability of the Berry Essential Oil of Two Subspecies of Juniperus Oxycedrus L. from Northwestern Algeria

open access: yesChemistry &Biodiversity, Volume 21, Issue 7, July 2024.
Abstract The chemical composition of 33 oil samples isolated from the berries of individual trees of two subspecies of Juniperus oxycedrus L., collected in four locations in Tlemcen and Aïn Temouchent provinces, was investigated by GC‐FID, GC/MS and 13CNMR. In total, 83 compounds were identified, accounting for 85.9 % to 98.6 % of the total composition.
