Single crystal AlN fibers [110] elongated up to 20 mm length and up to 40 μm diameter were obtained by self-propagating high-temperature synthesis (SHS) starting from a mixture of Al, AlN and NH4Cl under 100 atm. of N2. Two types of fibers were obta

Changes in the microstructure and texture of a silica xerogel have been studied through out the gel to glass conversion temperature. A molar ratio H 2 O/TEOS=4 was used to obtain silica xerogel. Different samples were treated at 400, 600, 800, 1000°

Responding at low rates was differentially reinforced in each of two components of a multiple schedule. In order to study the relative contributions to behavioral contrast in one component of the rates of responding, and of reinforcement in a second

A conditional discrimination was established and analyzed, using four pigeons. The discrimination was among four compound stimuli projected on the response key—a white circle or triangle on a red or green background—during two conditions of illum

Following bilateral ablation of portions of the fore-brain, pigeons retained their usual, pre-operative performance on the fixed-ratio component of a multiple schedule, but had strikingly abnormal performances on the fixed-interval component.
