Baited pesticide-treated biodegradable spheres were evaluated for their efÞcacy to control and monitor apple maggot, Rhagoletis pomonella (Walsh), and blueberry maggot, R. mendax Curran, ßies. A Plexiglas pane treated with sprayable Tangle-Trap was found to be an effective technique for assessing the fate of Rhagoletis ßies encountering treated spheres. SigniÞcantly more R. pomonella and R. men...

In this study, we describe the design of a tactile sensor based on polyvinylidene fluoride (PVDF). The sensor exhibits high force sensitivity and linearity. This sensor is integrated with an endoscopic grasper tool and can be used in minimally invasive surgeries. It consists of three distinct layers. A rigid micro-machined tooth-like silicon constitutes the top layer of the grasper, and the Ple...

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.
