Parasitic drag. Parasitic drag, also known as profile drag, [ 1]: 254 [ 2]: 256 is a type of aerodynamic drag that acts on any object when the object is moving through a fluid. Parasitic drag is a combination of form drag and skin friction drag. [ 3][ 1]: 641–642 [ 4]: 19 It affects all objects regardless of whether they are capable of ...
Standby power, also called vampire power[ 1], vampire draw, phantom load, ghost load or leaking electricity refers to the way electric power is consumed by electronic and electrical appliances while they are switched off (but are designed to draw some power) or in standby mode. This only occurs because some devices claimed to be "switched off ...
Parasitism is a kind of symbiosis, a close and persistent long-term biological interaction between a parasite and its host. Unlike saprotrophs, parasites feed on living hosts, though some parasitic fungi, for instance, may continue to feed on hosts they have killed.
Parasitic plant. Cuscuta, a stem holoparasite, on an Acacia tree in Pakistan. A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which ...
Parasitic load or parasitic loss may refer to. in internal combustion engines, it refers to devices that take energy from the engine in order to enhance the engine's ability to create more energy or convert energy to motion. in electrical appliances, it represents the power consumed even when the appliance is shut off. With regard to railway ...
Protozoa ( sg.: protozoan or protozoon; alternative plural: protozoans) are a polyphyletic group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic debris. [ 1][ 2] Historically, protozoans were regarded as "one-celled animals".
Parasitic capacitance or stray capacitance is the unavoidable and usually unwanted capacitance that exists between the parts of an electronic component or circuit simply because of their proximity to each other. When two electrical conductors at different voltages are close together, the electric field between them causes electric charge to be ...
One of the largest fields in parasitology, medical parasitology is the subject that deals with the parasites that infect humans, the diseases caused by them, clinical picture and the response generated by humans against them. It is also concerned with the various methods of their diagnosis, treatment and finally their prevention & control.
