Dog appeasing pheromone is secreted by lactating dogs. Dog appeasing pheromone (DAP), sometimes known as apasine, is a mixture of esters of fatty acids released by the sebaceous glands in the inter-mammary sulcus of lactating female dogs. It is secreted from between three and four days after parturition and two to five days after weaning. [1]
dose area product (DAP) measured in gray centimeters 2; dose length product (DLP) measured in gray centimeters; rads a deprecated unit of absorbed radiation dose, defined as 1 rad = 0.01 Gy = 0.01 J/kg; Roentgen a legacy unit of measurement for the exposure of X-rays; Each measure is often simply described as ‘dose’, which can lead to ...
Dose area product (DAP) is a quantity used in assessing the radiation risk from diagnostic X-ray radiography examinations and interventional procedures, like angiography.It is defined as the absorbed dose multiplied by the area irradiated, expressed in gray-centimetres squared (Gy·cm 2 [1] – sometimes the prefixed units dGy·cm 2, mGy·cm 2 or cGy·cm 2 are also used).

Drugs come with a recommended dose in milligrams or micrograms per kilogram of body weight, and that is used in conjunction with the patient's age and body weight to determine a safe dose. In single-dose scenarios, the patient's body weight and the drug's recommended dose per kilogram are used to determine a safe one-time dose.
DVH summarizes 3D dose distributions in a graphical 2D format. In modern radiation therapy, 3D dose distributions are typically created in a computerized treatment planning system (TPS) based on a 3D reconstruction of a CT scan. The "volume" referred to in DVH analysis is a target of radiation treatment, a healthy organ nearby a target, or an ...
The median effective dose is the dose that produces a quantal effect (all or nothing) in 50% of the population that takes it (median referring to the 50% population base). [6] It is also sometimes abbreviated as the ED 50, meaning "effective dose for 50% of the population". The ED50 is commonly used as a measure of the reasonable expectancy of ...
Traditionally, video motion analysis has been used in scientific circles for calculation of speeds of projectiles, [2] or in sport for improving play of athletes. Recently, computer technology has allowed other applications of video motion analysis to surface, including things like teaching fundamental laws of physics to school students, or general educational projects in sport and science.
