A new design of equilibrator for carbon dioxide monitoring in natural waters is described. It consists in a vertical tube filled with marbles through which water is flowing while equilibrating with a closed air circuit. It offers several advantages compared with classical equilibrators, among which is a fast response time (half-life constant approximately 30 s) and the potential to work in very...

How do people manipulate their environment when balancing trade-offs between probability of success and payoff? Individuals in a city park played a simple lottery using a small set of marbles placed in an urn. Participants had the ability to actively improve their chances of winning but only by reducing the amount of money that they could possibly win. Hence, participants controlled the lottery...

Through the amide formation between amine-functionalized polyhedral oligomeric silsesquioxane (POSS) and oxygen-containing groups (e.g., epoxy and carboxyl groups) in graphene oxide (GO), we have synthesized POSS-functionalized graphene nanosheets (POSS-graphene), which are highly soluble in various organic solvents attractive for multifunctional applications. Thin films from solution casting o...

as good as his little sister Maria. He does nothing but play marbles. I can't even send him to the store because he never brings home what I tell him to." The general tenor of this dissertation was repeated every time I saw her in the future. I devoted my first lesson to letting Joseph read the story of The Little Red Hen, pp. 1-9, Winston Primer. He read with great difficulty, spelling the wor...

A \trip" is a triple (g; u; v) where g is, in general, a graph and u and v are nodes of that graph. The trip is from u to v on the graph g. For the special case that g is a tree (or even a string) we investigate ways of specifying and implementing sets of trips. The main result is that a regular set of trips, speciied as a regular tree language, can be implemented by a tree-walking automaton th...

This article introduces the concept of monumental preservation, which the author defines as the preservation of all cultural phenomena, because from the smallest item to the greatest monument all things emanate from and reflect culture. The imperative to preserve monuments is the imperative to preserve our cultural heritage. Whether there is a moral responsibility to preserve cultural heritage ...
