Assessment of aqueous extract of Gypsophila aretioides for inhibitory effects on calcium carbonate formation

Green Processing and Synthesis, 2019
The aqueous extract of Gypsophila aretioides roots as a “green” or eco-friendly inhibitor of carbonate calcium formation was investigated. The presence of chelating factors such as polyphenol compounds and foaming agents in the plant extract was assessed.

Excitable neurons, firing threshold manifolds and canards [PDF]

, 2013
We investigate firing threshold manifolds in a mathematical model of an excitable neuron. The model analyzed investigates the phenomenon of post-inhibitory rebound spiking due to propofol anesthesia and is adapted from McCarthy et al. (SIAM J. Appl. Dyn.

Impulsivity in cocaine-dependent individuals with and without attention-deficit/hyperactivity disorder [PDF]

, 2015
<b><i>Background:</i></b> Cocaine-dependent individuals (CDI) display increased impulsivity. However, despite its multifactorial nature most studies in CDI have treated impulsivity monolithically. Moreover, the impact of attention-

Are language production problems apparent in adults who no longer meet diagnostic criteria for attention-deficit/hyperactivity disorder? [PDF]

, 2012
In this study, we examined sentence production in a sample of adults (N = 21) who had had attention-deficit/hyperactivity disorder (ADHD) as children, but as adults no longer met DSM-IV diagnostic criteria (APA, 2000).
