The signal to noise ratio for these measurements is optimized by reducing the contribution of scattered radiation and of system noise. The CT principle of image reconstruction is also applicable in nuclear medicine imaging, with the goal of achieving contrast improvement and quantitative assessment of ...
The TEM’s principle uses transmitted electrons as the name suggests. It gives valuable information about the sample’s internal structure, morphology, tension, and sample composition, while SEM gives information about the sample’s surface and the shape. The incident electron beam diffracts the ...

Chapter 1. Basic aspects of atom The atomic physics is the products of the first third of 20 th century. The study of the micro-world of atoms caused a revolution of physical thoughts, a revolution of fundamental ideas of classical physics, such as ...
To facilitate the standard practice of therapeutics based on the principle of evidence-based medicine, updated guidelines for esophageal cancers are published by the National Comprehensive Cancer Network.97 The Japan Esophageal Society has also edited guidelines for the diagnosis and treatment of ...
A single semiconductor with a bandgap of 1.6–2.0 eV could in principle enable the overall reaction.[89, 94] However, due to the low photovoltage (as limited by the difference between the flatband potential of the semiconductor and the electrochemical potential of the desired reactions) and the...
[…] Because the allosteric site need not, and typically does not, resemble the active site, any signal can, in principle, be used to control the function of any appropriately designed protein. (Ptashne and Gann 2002: 6f.) Regulators, i.e., activators and repressors, play the role of ...
