The surface area can also be reduced by storing the water in a compartmented reservoir, and pumping the water from one compartment to another as the water is used, so that there are some full compartments and some empty, instead of a single shallow sheet when the reservoir is partly used (Cluff 1981).
While pressure and flow are related physical phenomena, they should be considered separately for one primary reason: pressure pulses propagate through the brain at the speed of sound and the exact point of measurement is usually not of great interest, while flow requires the displacement of fluid from one compartment to another and flow pulsations vary dramatically depending on location.
The position of the animal and crossings from one compartment to the other were detected by two photocells placed on either side of the dividing wall.
The cell being a highly compartmentalized and dynamic entity requires for its survival the precise transport of certain molecules from one compartment to another and a regulation of this transport depending on its current physiological state.
Liquid can flow from one compartment to the other through openings at the top and the bottom of the baffle.
The transfer of a fatty acid from the cytoplasm to the mitochondrial matrix thus occurs without the transfer of CoA itself from one compartment to the other.
Traffic of proteins within the secretory pathway is directed by cargo-bearing vesicles that transport proteins from one compartment to another.
Box hedges are kept low, so they can be crossed with an easy stride to make movement from one compartment to another as simple as possible when tending the garden.
Such electrochemical system can be indicated as bipolar porous electrode with internal mass transfer and can be employed in practical applications to prevent the migration of unwanted ionic species from one compartment to the other of an electrolysis cell.
The nucleotides synthesized from exogenously supplied purines must mix with those made de novo at some point prior to their polymerization into nucleic acids, and it has been suggested that ethidium bromide interferes with this mixing process, which may be considered to be a movement of nucleotides from one compartment into another1.
In many cases, these tubes provide a barrier that separates different biological compartments (often the 'outside' from 'inside' of the organism) and regulate ionic homeostasis by vectorial transport of ions and solutes across the barrier from one compartment to the other.
