X-ray Theses Samples For Students

Introduction:

Nanobiotechnology serves as an imperative technique in the development of clean, nontoxic, and eco-friendly procedures for the synthesis and congregation of metal NPs having the intrinsic ability to reduce metals by specific metabolic pathways. Silver nanoparticles are particularly interesting nanoscale systems due to the ease with which they can be synthesised and modified chemically. Synthesis of silver nanoparticles has been widely researched due to their interesting size and shape-dependent properties [26]. These novel properties can be tailored by controlling their size, shape, composition, structure and crystallinity. Due to their size features and advantages over available anti-microbial properties, chemical imaging ...

Introduction

It is generally noted that the development of dosimeters to measure neutron exposures has been slow for many years in comparison to the development of gamma and x-ray dosimeters. Exposures to x-rays and gamma rays have been determined from glass dosimeters and film badges. By applying these dosimeters, personnel exposure to radiations caused by radioactive substances can be measured to standard accuracy. However, the uncertainty may arise due to variation in readings as a result of orientation of the wearer of the dosimeter to the source during exposure. On the other hand, NTA film has been the only neutron dosimeter ...

Even with the stricter security measures that have been put in place in the U.S. since September 11, 2011, a terrorist attack like that planned by Nizar Hindawi and the Syrian government against an El Al plane might have succeeded. He had been provided with a suitcase bomb containing Semtex, which was virtually undetectable by x-ray or other screening devices, and was using a ‘cut-out’ to actually carry the bomb aboard the plane, an accomplice who did not know she had a bomb and would have been killed with the rest of the passengers had it gone off. Only a very alert security staff ...
