Conransporters as molecular water pumps
2002Molecular water pumps are membrane proteins of the cotransport type in which a flux of water is coupled to substrate fluxes by a mechanism within the protein. Free energy can be exchanged between the fluxes. Accordingly, the flux of water may be relatively independent of the external water chemical potential and can even proceed uphill. In short, water

Cuticular Water Pump in Insects
Nature, 1967AMONG the ways in which terrestrial arthropods can control their environmental water relations, the active retention of water1, the regulation of water loss2, and the active uptake of atmospheric water3 have been found to be concerned with the movement of water through the cuticle.

There is good evidence that cotransporters of the symport type behave as molecular water pumps, in which a water flux is coupled to the substrate fluxes. The free energy stored in the substrate gradients is utilized, by a mechanism within the protein, for the transport of water.

Abstract The left-way cyclic process, introduced in the preceding paper, is described for obtaining water out of air. Two working methods are utilized. The first one delivers drinking water out of air without any service, maintenance, etc. The second method requires opening a cover above the absorbent during the evening.

The water jet pump, when designed with experimentally obtained optimum dimensions, can achieve efficiencies in the range of 35% to 40%. The design depends on the selected nozzles and diffuser, as well as the other parts of the pump, so that the hydraulic losses incurred are kept to a minimum.

The Water ATM system is a practical solution to provide water to individuals in a controlled and automated manner. Using an Arduino-based platform, this system incorporates an RFID reader (EM18) for user identification and an LCD display (20x4) to show essential details such as remaining balance, the status of the transaction, and time remaining.
