The universal quantifier each is more strongly distributive than its counterparts every and all. It forces predicates to apply to individuals, it more often supports pair-list readings, it’s unfriendly to genericity, and, in psycholinguistic tasks, it encourages encoding and remembering individual properties. But what information leads learners to acquire this aspect of em>each’s meaning? We explore the hypothesis that, because of its meaning, parents are more likely to use each in situations that independently promote representing the domain of quantification as a series of individuals (as opposed to a group). In line with this, we find that in child-directed speech, parents often use each to quantify over small numbers of physically present things. The same cannot be said of every and all. Because such situations are independently known to trigger object-files – the mind’s system for representing individuals – we argue that these cases are ideal for acquiring the individualistic aspect of each.

-Many efforts have been made to develop amine-based solid adsorbents for capture of CO 2 by adsorption. Compared with the traditional process of absorption in aqueous solutions of amines, the adsorbents with amine immobilized in solids generally result in processes with lower capital and energy costs. The literature contains some experimental studies of CO 2 adsorption in impregnated materials; however, few studies are devoted to the theoretical interpretation of this system in terms of CO 2 capture for post-combustion (N 2 mixture with a low partial pressure of CO 2 ). Therefore, this study investigates the adsorption of a CO 2 :N 2 mixture on zeolite NaX impregnated with monoethanolamine (MEA), using molecular simulation. A model of NaX impregnated with MEA was proposed and the adsorption of a 15:85 (CO 2 :N 2 ) mixture was investigated based on the Monte Carlo method. The simulation of the MEA impregnated zeolite at 25 °C predicted higher CO 2 selectivity and significant improvement in the heat of adsorption. Unfortunately, the adsorption heat improvement did not translate into corresponding increases in the amount of adsorbed CO 2 . Moreover, MEA concentrations higher than 12 wt% hindered the adsorption of CO 2 molecules. An explanation for the results in terms of occupied volumes and interaction energies is presented.
