The magnetic field of the Moon is very weak in comparison to that of the Earth; the major difference is the Moon does not have a dipolar magnetic field currently (as would be generated by a geodynamo in its core), so that the magnetization present is varied (see picture) andRead More →
Progress in photonics provides the opportunity to replace electron flow, for transmission and computing, with a photonic flow or a plasmonic flow; harnessing the interaction between the surface electrons of nanostructured circuits and photons. Are we already using photonics in any field? Photonics plays an important role in driving innovationRead More →

The receptive field encompasses the sensory receptors that feed into sensory neurons and thus includes specific receptors on a neuron as well as collectives of receptors that are capable of activating a neuron via synaptic connections. What cells have receptive fields? The cells whose receptive fields thus respond to lightRead More →
Do not sneeze, cough, laugh, or talk over the sterile field. Maintain a safe space or margin of safety between sterile and non-sterile objects and areas. Refrain from reaching over the sterile field. Keep operating room (OR) traffic to a minimum, and keep doors closed. What is proper surgical attireRead More →
In uniform electric field, the electric field lines are parallel. Why are field lines parallel? When the electric field in homogeneous dielectric between two wide and flat metal plates which are placed in parallel with each other and charged with the same magnitude and opposite signs. Then the electric fieldRead More →

Healthcare professionals use aseptic technique to protect patients from infection. Aseptic technique is a standard healthcare practice that helps prevent the transfer of germs to or from an open wound and other susceptible areas on a patient’s body. What is the concept of asepsis? Definitions. Asepsis – is the absenceRead More →
The aperture is the setting that beginners typically use to control depth of field. The wider the aperture (smaller f-number f/1.4 to f/4), the shallower the depth of field. How does f-stop affect depth of field? The lower the f/stop—the larger the opening in the lens—the less depth of field—theRead More →
