Improving barrier properties through the use of nanocomposites is an important area of research, especially for the food packaging industry. In this work, Titanium dioxide (TiO2 )/Low density Poly Ethylene (LDPE) nanocomposites were synthesized as the oxygen barrier layers through the co-extrusion process. The Oxygen permeability of the nanocomposite with 4% of TiO2 decreased for about 16% comp...

The ground state energies of two interacting electrons confined in a coupled double quantum dot (DQD) presented in a magnetic field has been calculated by solving the relative Hamiltonian using variational and exact diagonalization methods. The singlet-triplet transitions in the angular momentum and spin of the quantum dot ground state had been shown .We have studied the magnetic field versus c...

hexavalent chromium is mobile and hazardous in the environment. electrokinetic remediationof chromium (iv)-contaminated soils is intended either to remove or to reduce cr (vi) to cr (iii). this studyexamines the effectiveness of utilizing edta and acetic acid solutions as alternative electrolytes in theelectrokinetic (ek) process, with coupled nano-scale zero-valent iron (nzvi) as a barrier for...

background: to evaluate and compare the efficacy of mineral trioxide aggregate (mta) and traditionally used calcium hydroxide (ca(oh)2) in inducing root end formation of immature roots of traumatized young permanent anterior teeth. materials and methods: the study was carried out on 22 nonvital, immature permanent maxillary incisors. samples were allotted into two groups – group i mta and group...

Multiple sclerosis (MS) is a chronic autoimmune disorder affecting the central nervous system (CNS) through demyelination and neurodegeneration. Several lines of evidence support a role for oxidative and nitrative stress (OS and NS) in pathogenesis of multiple sclerosis. The mechanism of influence of OS and NS on blood-brainbarrier (BBB) has critical importance for evaluating antioxidant therap...

Background: The central nervous system (CNS) may no longer be considered immune privileged but rather a site of selective immune activity. Although the bloodbrain barrier (BBB) covers most parts of the CNS, certain brain regions are devoid of it and are, therefore, in permanent contact to blood-born molecules and cells. These “exposed” areas include the choroid plexus and other small structures...

Recent research has clarified many of the clinical applications of L-Carnitine and its related compounds, leading into new areas of potential use. Promising therapeutic applications of an ester form of carnitine, acetyl-L-Carnitine (ALC) are derived from observations that this compound readily crosses the bloodbrain barrier and improves neuronal energetics and repair mechanisms while modifying ...
