A two-compartment Plexiglas cell has been set up and tested for separate hydrogen and oxygen production from photocatalytic water splitting on a thin TiO2 layer deposited by magnetron sputtering on a flat Ti electrode inserted between the two cell compartments.

Behavior geneticists have long sought to display learning in the fruit fly (Drosophila melanogaster), but previous research efforts have proven problematic. The following describes a maze apparatus and a procedural technique that have produced positive results in learning tasks with negative geotaxis flies. The Plexiglas maze is inexpensive to construct and offers a functional versatility that ...

It is known that the natural convection (NC) solar drying process a simple and cheap method for foodstuffs, but it not preferable common users in case of high-moisture content agro-products due to slow rate drying. Meanwhile, forced (FC) most appropriate such products, its economic feasibility may be affected high initial maintenance costs. Therefore, present study proposed controlled (CNC) mod...

Tasks: 1. To measure the impulse counting rate as a function of the distance between the source and the counter tube. 2. To determine the half-value thickness d1/2 and the absorption coefficient of a number of materials by measuring the impulse countAttenuation coefficient of different materials as a function of the material density (from left to right: Plexiglas®, concrete, aluminium, iron, le...

A device is described which consists of a bonded Plexiglas-silicone rubber plate, perforated to hold capillary pipettes in register with the wells of a plastic tray to be inoculated. Pipette contents are simultaneously discharged by positive air pressure, initiated by closing an exhaust port with the thumb.

Darters represent a substantial radiation of freshwater fishes that live in close association with the substrate in North American streams and rivers. A key feature of any darter species is therefore its ability to stay in place or to "hold station" in flowing water. Here, we quantify the station-holding performance of two morphologically divergent darter species, the fantail darter Etheostoma ...
