In cellular studies of habituation, such as in the gill and siphon withdrawal reflex to tactile stimulation of the siphon of Aplysia, a mechanism that has emerged as an explanation for response decrement during habituation is homosynaptic depression at sensory neurons mediating the behavioral response. We have examined the contribution of homosynaptic depression to habituation in sensory neuron...

Solar-assisted distillation is considered promising to solve the freshwater supply for off-grid communities. In this work, a passive and flexible multistage membrane (F-MSMD) device devised produce via solar with latent heat of vapor condensation being recycled enhance its energy efficiency. By designing siphon effect, source water continuously wicked into evaporation layer concentrated brine f...

The defensive withdrawal reflex of the mantle organs of Aplysia californica has 2 major components, siphon withdrawal and gill withdrawal. In the previous paper of this series (Rankin and Carew, 1987), the development of 2 forms of nonassociative learning, habituation and dishabituation, was examined in the siphon withdrawal component of the reflex. In the present study we examined these same f...

We wish to acknowledge a related 1995 experiment performed by Andrew K Fletcher (http://inclinedbedtherapy. com), in which a 48 m length of 6 mm bore tubing, filled with degassed water was lifted 24 m vertical against Brixham Cliffs. A 50 ml bolus of coloured saline solution in the middle of the 48 m tubing was introduced prior to the tubing being raised to 24 metres vertical by its centre as a...

A novel concept for the deflection of rotating asteroids is presented, based on conversion asteroid rotational kinetic energy into translational energy. Such achieved using an orbital siphon, a tether-connected chain masses, arranged vertically from surface, which exploits rotation delivery mass to escape. Under conditions be discussed, siphon can initiated ensure self-sustained flow This mecha...

In a recent paper Bellot Rubio et al. (1997) inverted Zeeman split Stokes profiles to infer the stratification of the temperature, velocity and magnetic field in the photospheric layers of solar magnetic elements (modeled as thin flux tubes). One controversial result of their inversions is the presence of a strong downflow within the flux tubes. In the model underlying their inversion such a do...
