Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to s...

Zeolite as a catalyst can increase its activity by carrying out physical and chemical activation processes. Physical be activated reducing the size of zeolite through grinding sieving methods, from process it surface area zeolite. In this study, was chemically acid method immersing natural with HCl HF. The oxide compound in characterized using XRF. used to reduce free fatty levels variations ad...

Abstract. Aerosols play a crucial role in the fog life cycle, as they determine droplet number concentration and hence size, which turn controls both fog's optical thickness lifespan. Detailed aerosol-microphysics schemes accurately represent formation growth are unsuitable for weather forecasting climate models, computational power required to calculate would dominate treatment of rest physics...

PURPOSE Retinal prostheses are an approved treatment for vision restoration in retinal degenerative diseases; however, present implants have limited resolution and simply increasing the number of electrodes is limited by design issues. In cochlear implants, virtual electrodes can be created by simultaneous stimulation of adjacent physical electrodes (current steering). The present study assesse...
