Concentration

Often in informal, non-technical language, concentration is described in a qualitative way, through the use of adjectives such as "dilute" for solutions of relatively low concentration and "concentrated" for solutions of relatively high concentration. To concentrate a solution, one must add more solute (for example, alcohol), or reduce the amount of solvent (for example, water).

What does ''tsundoku'' mean?

 · "Tsundoku" is a term that refers to the accumulation of books without ever leafing through them. This term appeared in the 19th century and is still relevant today. Because despite the increase in book sales in many regions of the world, the stress caused by the global health crisis may have played havoc with the concentration abilities of would-be readers.

Riffle

A riffle is a shallow landform in a flowing channel, and it has specific topographic, sedimentary, and hydraulic indicators. These are almost always assessed at a very low discharge compared to the flow that fills the channel (approximately 10–20%), and as a result the water moving over a riffle appears shallow and fast, with a wavy, disturbed water surface.
