Transepithelial movement of water and solute occurs both through the cell membrane as well as across the intercellular junctional complex (paracellular shunt pathways). Permeability of paracellular shunt pathways is increase by transmucosal osmotic gradients, and in certain epithelia these changes are associated with bullous-like deformations (blisters) of the zonula occludens and localization ...
an improved, simple, and facile synthesis of 3,4-dihydropyrimidin-2(1h)-ones by employing three-component, one-pot condensation reaction of β-keto ester, aromatic aldehydes, and urea or n-methylurea using lacl3/clch2cooh as an inexpensive and green chemistry catalyst system under solvent-free conditions described. compared with the classicalbiginelli reaction conditions, this method has the adv...
This data article describes a facile method for production of an adsorbent from Tamarix hispida wasted wood and modified by lanthanum metal for fluoride ions removal from wastewater. The main characteristics of the adsorbent consist of BET surface area, functional groups, and elemental analysis is presented. The data for attenuating the pollutants from a real wastewater treatment which was prov...
It was discovered recently that the charge of gas bubbles in aqueous solution can be reduced and even reversed by the addition of multivalent inorganic saltsIn this work. the effect of LaCI3 on the charge of bubbles was investigated and found to have an effect similar to that previously observed with AICI3 and MgC12The electrokinetic behavior of gas bubbles was affected slightly by LaCI3 additi...
Chondroitin sulfate occurs in bovine nasal cartilage as compounds with protein called proteinpolysaccharides (PP) of which there are two kinds: (a) the major part is not sedimented at 100,000 X g and is called PP-L; (b) the smaller part is readily sedimented at 10,000 X g and is called PP-H (1). Both, on treatment with NaOH (0.15 in, 25”, 16 hours), yield chondroitin sulfate in amounts correspo...
Lanthanum hexaboride nanowires produced by chemical vapor deposition are single-crystalline and grown along the [111] direction. Streaks appearing in the electron diffraction spots indicate the lateral direction perpendicular to the nanowire growth axis.
The paramagnetic insulator to ferromagnetic metal transition in Lanthanum manganites and the associated magnetoresistive phenomena is treated by considering the localization due to random hopping induced by slowly fluctuating spin configurations and electron-electron interactions. The transition temperature and its variation with composition is derived. The primary effect of the magnetic field ...
In quantum field theory, Weyl fermions are relativistic particles that travel at the speed of light and strictly obey the celebrated Lorentz symmetry. Their low-energy condensed matter analogs are Weyl semimetals, which are conductors whose electronic excitations mimic the Weyl fermion equation of motion. Although the traditional (type I) emergent Weyl fermions observed in TaAs still approximat...
