This article highlights effect of radiation exposure on foetus.I would like to discuss about the amount of radiation exposure in a pregnant woman during fluoroscopic guided closed femoral Interlock nailing as radiation has significant...

Hawking radiation in moving plasmas

Bi-metricity and Hawking radiation are exhibit in non-relativistic moving magnetohydrodynamics (MHD) plasma medium generating two Riemannian effective spacetimes. The first metric is a flat metric although the speed of ”light” is given by a time dependent signal where no Hawking radiation or effective black holes are displayed. This metric comes from a wave equation which the scalar function co...

Radiation exposure in pediatric dentistry: Current standards in pedodontic radiology with suggestions for alternatives

Introduction The most frequent radiographic examination for children is a dental radiographic examination. During the years from 1961 to 1970, there was a 34% increase in the number of dental radiographic visits for children (Table 1). During this same interval, there has been decline in the average number of films exposed per visit. The trend, therefore, is for increasing numbers of children t...

Moving Field Radiation Therapy

divides into the Lorisiform lemurs and the Lemuriform lemurs. There is some justification for this, yet the unique features of the Malagasy (Lemuriform) lemurs does argue that the nocturnal lorises of Asia and Africa are better kept in a separate category. But here we go arguing terminology, a deplorably bad habit which Sir Wilfred has noted is a characteristic trait of students of the Primates...
