Ether anesthesia following one-trial passive avoidance conditioning interferes with the acquisition of the avoidance response (Abt, Essman, & Jarvik, 1961). The amount of the interference decreases as the interval between learning (footshock) and administration of ether increases (Alpern & Kimble, 1967; Pearlman, 1966). These results are typically interpreted to mean that ether disrupts memory ...

Background: The aim of this work was to study the output factors for Linac using different ionization chambers and build up caps. Materials and Methods: Output factors were measured for open square fields (3 × 3 cm to 40 × 40 cm) defined by collimator jaws for 6 and 15 MV photon beams from a Varian Clinac 2100C accelerator were measured. The measurements in air were performed using Com...

Introduction Hadron-therapy is an effective technique used to treat tumors that are located between or nearby vital organs. The Italian National Center of Oncological Hadron-therapy (CNAO) has been realized as the first facility in Italy to treat very difficult tumors with protons and Carbon ions. The on-line monitor system for CNAO has been developed by the Department of Physics of the Univers...

Abstract Aims Species diversity–productivity relationships in natural ecosystems have been well documented the literature. However, biotic and abiotic factors that determine their are still poorly understood, especially under future climate change scenarios. Methods Randomized block factorial experiments were performed three meadows along an elevational gradient on Yulong Mountain, China, where...
