Temperature and Concentration Induced Complex Behavior in Ternary Microemulsion

open access: yesApplied Rheology, 2013
Viscosity measurements were performed in water/AOT (sodium bis(2-ethylhexyl) sulfoccinate)/isooctane microemulsions as a function of temperature between 25 and 55°C, molar ratio W0 = water/AOT ranging from 3 to 45 and three values of AOT/isooctane volume

Analyse par RMN

open access: yes, 2009
Deux cas d'intoxication volontaire par un herbicide sont rapportés chez deux hommes de 51 et 52 ans. L'analyse par spectroscopie RMN-1H du désherbant a permis de montrer qu'il contenait essentiellement deux herbicides chlorophénoxylés : l'acide 2-(2 ...

Radio mean labeling of a graph

open access: yesAKCE International Journal of Graphs and Combinatorics, 2015
A Radio Mean labeling of a connected graph G is a one to one map f from the vertex set V(G) to the set of natural numbers N such that for two distinct vertices u and v of G, d(u,v)+⌈f(u)+f(v)2⌉≥1+diam(G).

Organocatalyzed Ring‐Opening of Vinylene Carbonates With Amines to Oxazolidinones

open access: yesChemCatChem, Volume 18, Issue 21, 12 November 2026.
The organocatalytic ring‐opening of vinylene carbonates with amines provides 4‐hydroxyoxazolidin‐2‐ones with 100% atom‐economy. The reaction proceeds at room temperature and operates at low catalyst loading . ABSTRACT The organocatalyzed ring‐opening of vinylene carbonates with amines was studied using diphenyl‐1,3‐dioxol‐2‐one as a model substrate to ...

Assessment of Lectin Staining Biomarkers for GNE Myopathy Gene Therapy

open access: yesMuscle &Nerve, Volume 74, Issue 5, Page 1456-1470, November 2026.
ABSTRACT Introduction/Aims GNE myopathy (GNEM) is a rare, autosomal recessive disorder caused by mutations in the UDP‐N‐acetylglucosamine (GlcNAc) 2‐epimerase/N‐acetylmannosamine (ManNAc) kinase (GNE) gene, which encodes a required enzyme for sialic acid (SA) biosynthesis.
