Clark's rule is a medical term referring to a mathematical formula used to calculate the proper dosage of medicine for children aged 2–17 based on the weight of the patient and the appropriate adult dose. [ 1] The formula was named after Cecil Belfield Clarke (1894–1970), a Barbadian physician who practiced throughout the UK, the West ...
Body surface area. In physiology and medicine, the body surface area ( BSA) is the measured or calculated surface area of a human body. For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. Nevertheless, there have been several important critiques of the ...
To calculate the formula for the surface area and volume of a gyrobifastigium with regular faces and with edge length , one may adapt the corresponding formulae for the triangular prism. Its surface area can be obtained by summing the area of four equilateral triangles and four squares, whereas its volume by slicing it off into two triangular ...
In the field of pharmacokinetics, the area under the curve ( AUC) is the definite integral of the concentration of a drug in blood plasma as a function of time (this can be done using liquid chromatography–mass spectrometry [ 1] ). In practice, the drug concentration is measured at certain discrete points in time and the trapezoidal rule is ...
Gyroelongated square bipyramid. In geometry, the gyroelongated square bipyramid is a polyhedron with 16 triangular faces. it can be constructed from a square antiprism by attaching two equilateral square pyramids to each of its square faces. The same shape is also called hexakaidecadeltahedron[ 1], heccaidecadeltahedron, [ 2] or tetrakis square ...
A pyramid is a polyhedron that may be formed by connecting a polygonal base and a point, called the apex. Each base edge and apex form an isosceles triangle, called a lateral face. [7] The edges connected from the polygonal base's vertices to the apex are called lateral edges. [8] Historically, the definition of a pyramid has been described by ...
Spherical trigonometry. The octant of a sphere is a spherical triangle with three right angles. Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the sides and angles of spherical triangles, traditionally expressed using trigonometric functions. On the sphere, geodesics are great circles.
Daily dose tadalafil is available at a dosage of 2.5mg or 5mg tablets. There might be several reasons to go with daily dosages instead of the dosages where you take the medication as needed.
