Fresh water is crucial for life, supporting human civilizations and ecosystems, its production one of the global issues. To cope with this issue, we evaluated performance cost a solar-powered direct contact membrane distillation (DCMD) unit fresh in Karachi, Pakistan. The solar heating system (SWHS) was help advisor model (SAM) tool. evaluation DCMD performed by solving mathematical through num...

At extreme temperature, neurons cease to function appropriately. Prior exposure to a heat stress (heat shock [HS]) can extend the temperature range for action potential conduction in the axon, but how this occurs is not well understood. Here we use electrophysiological recordings from the axon of a locust visual interneuron, the descending contralateral movement detector (DCMD), to examine what...

• Single, dual, and triple-layered mixed matrix ENMs (MM-ENMs) were prepared. Multi-walled carbon nanotubes graphene oxide used as nanofillers. Water pockets formed in MM-ENMs with an internal hydrophilic layer. Combining thick thin hydrophobic layers improved DCMD performance. Optimal DL-MM-ENM had high permeate fluxes (74.7 kg/m 2 h) salt rejection (99.99%) Robust superhydrophobic electrospun...

Rind, F. Claire and Peter J. Simmons. Signaling of object ap16 mW/cm, and dark shapes of 4 mW/cm in intensity moved against it. Stimuli were controlled with a Cambridge Research proach by the DCMD neuron of the locust. J. Neurophysiol. 77: 1029–1033, 1997. The locust descending contralateral motion deSystems VSG2/1 board and RG2 raster generator, providing a refresh rate of 200 Hz, at a resolut...

Terminal lakes are water bodies that are located in closed watersheds with the only output of water occurring through evaporation or infiltration. The majority of these lakes, which are commonly located in the desert and influenced by human activities, are increasing in salinity. Treatment options are limited, due to energy costs, and many of these lakes provide an excellent opportunity to test...

Insect larvae clearly react to visual stimuli, but the ability of any visual neuron in a newly hatched insect to respond selectively to particular stimuli has not been directly tested. We characterised a pair of neurons in locust larvae that have been extensively studied in adults, where they are known to respond selectively to objects approaching on a collision course: the lobula giant motion ...

Direct contact membrane distillation (DCMD) is a promising means of concentrating brines to their saturation limit. During that process, spacers play key role in temperature polarization, concentration and mineral scaling. These interactions are not well understood, because they difficult study experimentally numerically, the flow regimes fully charted. We consequently develop tailored in-house...
