Effect of Tensile Stresses on the Evolution of Post-Compaction Properties of Sodium Chloride Tablets and Its Mixtures.

This study focuses on the effect of moisture on the strength of tablets of sodium chloride (NaCl) and its mixtures after compaction. We built on our prior work that proposed an explanation of the strengthening of NaCl tablets due to a dissolution-reprecipitation mechanism and the decrease in strength of NaCl-starch tablets due to the presence of residual stresses on NaCl-NaCl contacts in the mixture. Here, we offer experimental evidence that induced tensile stresses on NaCl slow down or negate (if large enough) the strengthening mechanism.

Prevalence of early repolarization syndrome and long-term clinical outcome in patients with the diagnosis of idiopathic ventricular fibrillation.

Idiopathic ventricular fibrillation (IVF) is diagnosed in up to 14% of sudden cardiac death (SCD) survivors. Early repolarization syndrome (ERS) in patients with ventricular tachyarrhythmia is characterized by an elevated J-point in inferior and/or antero-lateral leads. Our objectives were to determine the prevalence of ERS in IVF patients, and to evaluate potential differences in clinical outcome.

On the Post-Compaction Evolution of Tensile Strength of Sodium Chloride-Starch Mixture Tablets.

This study focuses on the evolution of mechanical behavior of starch and sodium chloride (NaCl) mixture tablets after compaction. This type of mixture has attracted attention in the past because such tablets exhibit lower tensile strengths than the ones of its individual components. Here we demonstrate that the strengths of NaCl-starch mixtures and NaCl tablets evolve after compaction in an opposite way.
