Glauber modeling of high-energy nuclear collisions at the subnucleon level [PDF]
, 2016 Glauber models based on nucleon--nucleon interactions are commonly used to characterize the initial state in high-energy nuclear collisions, and the dependence of its properties on impact parameter or number of participating nucleons.

Factors that influence the stability of the FDG
Saúde & Tecnologia, 2015 Introduction – The absence of a cyclotron for production of 2-[18F]Fluor-2- -deoxy-D-glucose (18F-FDG) is now a reality for most of the centers where Positron Emission Tomography (TEP) exams are held in. It is therefore important to ensure the quality of

Local, transient tensile stress on the nuclear membrane causes membrane rupture
Molecular Biology of the Cell, 2019 Cancer cell migration through narrow constrictions generates compressive stresses on the nucleus that deform it and cause rupture of nuclear membranes. Nuclear membrane rupture allows uncontrolled exchange between nuclear and cytoplasmic contents.

Severe Accident Simulation of the Laguna Verde Nuclear Power Plant
Science and Technology of Nuclear Installations, 2012 The loss-of-coolant accident (LOCA) simulation in the boiling water reactor (BWR) of Laguna Verde Nuclear Power Plant (LVNPP) at 105% of rated power is analyzed in this work. The LVNPP model was developed using RELAP/SCDAPSIM code.
