Cohesion is the grammatical and lexical linking within a text or sentence that holds a text together and gives it meaning. It is related to the broader concept of coherence. There are two main types of cohesion: grammatical cohesion: based on structural content; lexical cohesion: based on lexical content and background knowledge.
The cohesive particles adhere to the free-flowing particles (now called carrier particles) to form interactive units as shown in figure B. [3] An interactive mixture may not contain free aggregates of the cohesive powder, which means that all small particles must be adhered to the larger ones. The difference from an ordered mixture is instead ...
Cohesion allows for surface tension, creating a "solid-like" state upon which light-weight or low-density materials can be placed. Mercury exhibits more cohesion than adhesion with glass Rain water flux from a canopy. Among the forces that govern drop formation: cohesion, surface tension, Van der Waals force, Plateau–Rayleigh instability
As the adhesive solidifies, its internal strength, the cohesion, increases. The cohesion is also based on physical interactions, in this case between the adhesive polymers. In the case of adhesives which cure by a chemical reaction, i.e. the formation of polymers by a chemical reaction of the adhesive constituents, the resulting chemical bonds ...
The Hildebrand solubility parameter is the square root of the cohesive energy density: δ = Δ H v − R T V m . {\displaystyle \delta ={\sqrt {\frac {\Delta H_{v}-RT}{V_{m}}}}.} The cohesive energy density is the amount of energy needed to completely remove a unit volume of molecules from their neighbours to infinite separation (an ideal gas ).
Devices sold as siphons often come with a siphon pump to start the siphon process. In some applications it can be helpful to use siphon tubing that is not much larger than necessary. Using piping of too great a diameter and then throttling the flow using valves or constrictive piping appears to increase the effect of previously cited concerns ...

For example, one such form of this tracking uses audio beacons, or inaudible sounds, emitted by one device and recognized through the microphone of the other device. [3] This form of tracking is used primarily by technology companies and advertisers who use this information to piece together a cohesive profile of the user. [3]
