Two identified locust neurons, the lobula giant movement detector (LGMD) and its postsynaptic partner, the descending contralateral movement detector (DCMD), constitute one motion-sensitive pathway in the visual system that responds preferentially to objects that approach on a direct collision course and are implicated in collision-avoidance behavior. Previously described responses to the appro...

An integrated membrane distillation (MD) flowsheet, consisting of direct contact (DCMD) and vacuum (VMD) units, was proposed analysed in terms thermal performance water recovery factor, for the first time. The same lab-scale module (40 cm2) used carrying out experiments DCMD VMD at fixed feed operating conditions (deionised 230 L/h ~40 °C) while working permeate side with deionised 18 °C a 20 m...

A locust can make a tasty morsel for a hungry predator, so being able to notice potentially dangerous looming objects and trigger the correct response could save a locust’s life. In locusts, a visual neuron called the descending contralateral movement detector (DCMD) spikes in response to looming objects and could therefore be the trigger for escape responses. Tomas Money and colleagues at Quee...

Polyvinylidine fluoride (PVDF) hollow fiber and nanofibrous membranes are engineered and successfully fabricated using dry-jet wet spinning and electrospinning techniques, respectively. Fabricated membranes are characterized for their morphology, average pore size, pore size distribution, nanofiber diameter distribution, thickness and water contact angle. Direct contact membrane distillation (D...

Direct contact membrane distillation (DCMD) which emerges as an alternative separation technology can effectively perform a colloidal separation process under thermal driven force. DCMD is capable of extracting pure water from aqueous solutions containing non-volatile nanoparticles through the hydrophobic microporous membrane when a vapour pressure difference was established across the membrane...

The main obstacles to scaling up membrane distillation (MD) on a commercial level are fouling and temperature polarization. Therefore, in this study, the significance of pulsation feed flow phenomenon was used for (DCMD) polarization, comparisons were made using steady-state flow. Two different Hertz amplitudes trends DCMD sources water, including distilled seawater, wastewater. Compared flow, ...

Through experiments, the effect of membrane material selection and operating conditions on permeate fluxes in direct contact distillation (DCMD) desalination was investigated. The experiment used a plate frame module, with nine different hydrophobic porous membranes, comparative analysis performance 3 wt% NaCl solution performed. results this were compared to find out materials, pore sizes thic...

17 An increasing number of studies show how stimulus complexity affects the responses of 18 looming sensitive neurons across multiple animal taxa. Locusts contain a well described, 19 descending motion sensitive pathway that is preferentially looming sensitive. However, the 20 lobula giant movement detector/descending contralateral movement detector (LGMD/DCMD) 21 pathway responds to more than ...

direct contact membrane distillation (dcmd) which emerges as an alternative separation technology can effectively perform a colloidal separation process under thermal driven force. dcmd is capable of extracting pure water from aqueous solutions containing non-volatile nanoparticles through the hydrophobic microporous membrane when a vapour pressure difference was established across the membrane...
