background: the patterson-parker table was created in 1934 to determine mg-hr required to deliver the prescribed dose to the treatment area. these tables were created using the dosimetric data for 226ra that was determined in air and were utilized for dose calculations around implants with ra-equivalent radionuclides such as 137cs and 192ir. therefore, the differences of the tissue attenuation ...

Modeling statistical properties of motion of a Lagrangian particle advected by a high-Reynolds-number flow is of much practical interest and complement traditional studies of turbulence made in Eulerian framework. The strong and nonlocal character of Lagrangian particle coupling due to pressure effects makes the main obstacle to derive turbulence statistics from the three-dimensional Navier-Sto...

In this high-tech era, the targeted drug delivery system has various progressions in of cancerous drugs. current review, main purpose is to address valuable needs a all aspects safety and therapeutic The objective introduce carriers with their benefits. superior traditional because they overcome pros cons deliver dosage form at site without exhibiting any side effects. positive benefit that red...

A finite-volume dynamical core with a terrain-following Lagrangian control-volume discretization is described. The vertically Lagrangian discretization reduces the dimensionality of the physical problem from three to two with the resulting dynamical system closely resembling that of the shallow water system. The 2D horizontalto-Lagrangian-surface transport and dynamical processes are then discr...

— We prove that the Navier-Stokes, the Euler and the Stokes equations admit a Lagrangian structure using the stochastic embedding of Lagrangian systems. These equations coincide with extremals of an explicit stochastic Lagrangian functional, i.e. they are stochastic Lagrangian systems in the sense of [6].
