Latent Phase
Latent Phase
Chronic latent state refers to a persistent but inactive phase of a disease or condition where symptoms are not present but the causative agent (such as a virus or bacteria) remains in the body. This phase can last for an extended period without causing any symptoms or signs of active infection.
The phases of Acute Radiation Syndrome are the prodromal phase, manifest illness phase, latent phase, and recovery or death phase. The prodromal phase occurs within hours to days after exposure, with symptoms like nausea and vomiting. The manifest illness phase presents with symptoms specific to the level of radiation exposure, such as bone marrow suppression or gastrointestinal symptoms.
The correct order for the phases of Acute Radiation Syndrome (ARS) is prodromal phase, latent phase, manifest illness phase, and recovery or death phase. The prodromal phase typically occurs within hours to days after exposure, followed by a period of apparent recovery known as the latent phase. The manifest illness phase then presents with symptoms specific to the level of radiation exposure, followed by either recovery or death in the final phase.
The latent phase of Acute Radiation Syndrome is the period following exposure to high levels of ionizing radiation where symptoms are not yet apparent. It can last from hours to weeks, depending on the radiation dose. This phase is characterized by the body's attempt to repair damage caused by radiation exposure before the onset of visible symptoms.
Developing Phase
The energy involved in a phase change is called the latent heat. It is the amount of heat energy required to change the phase of a substance without changing its temperature.
Latent heat is the energy required for 1 kg of a substance to change ___________. phase
Prodromal, latent, and manifest
Latent heat is the energy absorbed or released by a substance during a phase change without a change in temperature.
The phase change number is a dimensionless number used in heat transfer that represents the ratio of sensible heat transfer to latent heat transfer during a phase change process. It helps quantify the relative importance of sensible and latent heat transfer mechanisms.
