This work presents a new method of fabricating implantable multielectrode arrays on lightly doped single-crystal silicon. Such arrays are essential tools for electrical stimulation and recording of nerve signals. Our new microfabrication process, based on silicon-on-insulator (SOI) technology, inherently has excellent control over the final probe thickness without wet etching. The needle shanks...

Chirality is not just a structural artifact in biology but it may provide for a genuine biological advantage. This is due to the phenomenon of chiral interaction (CI) which is described here for mechanical-chiral devices. The main mechanical feature of chiral interaction is its mode of selecting one direction of rotation out of two possible and opposite ones. For example, a given chiral device ...

The evaporation of sprinkler droplets is an important phenomena in fire simulations both for heat removal from the gas and for heat removal from surfaces. The Fire Dynamics Simulator (FDS) has seen a number of different evaporation models over its history where each subsequent model has attempted to address limitations and issues with the previous model. In this paper, we address the problems o...

Sprinkler skipping is an important issue in fire spread. In general, two sprinklers are installed air conditioner rooms at the ceiling and 30 cm below to avoid spray failure by energy recovery ventilator ceiling. However, there a problem that sprinkler occurs room. this study, phenomenon was analyzed through numerical analysis applicability of open type operation method reviewed. As result, whe...

The simultaneous paver liquid cement sprinkling system is the combination of a conventional and sprinkler. During operation, sprinkler can be installed onto with use connectors. When paving stabilization aggregate mixture, this sprinkles on working surface. This device effectively solve common quality issues such as formation isolation layer road pollution, result premature hardening pre-sprink...

In the Mesilla Valley of southern New Mexico, furrow irrigation is the primary source of water for growing onions. As the demand for water increases, there will be increasing competition for this limited resource. Water management will become an essential practice used by farmers. Irrigation ef®ciency (IE) is an important factor into improving water management but so is economic return. Therefo...
