units causes a change in the reference frequency of 6.4 PPM (1/156250). Once again, this might not sound like much, but considering that you might want to keep within 50 microseconds from the system time, it could mean that you exceed that limit after a few seconds without...
The amount of Th-229 should be represented as ppm per final Ac-225 activity. For Ra-225 contamination (40 keV, 30% yield) can be measured after ~ 12 h, if no Ra-225 present, minimal detectable activity (MDA) should be used. Radio-HPLC analysis As previous research shows the ...
All qualitative data were imported into NVivo 12 Pro data software managing tool. A deductive thematic analysis was employed using the domains and constructs outlined in the updated CFIR [11] as a guide. Not all constructs were represented in the focus group transcripts and emergent areas were n...
The GIWAXS technique is a powerful tool for the collection of 2D brag diffractions (spots, arcs, or rings) from certain crystal planes, enabling accurate phase identification and orientation analysis23,24,25,26,27. We first adopted ex-situ GIWAXS to investigate the crystallization of PEA-based...
In order to cope with the need for a higher flexibility (to test, compare and use new line broadening models) and with the request for additional features, the existing code imple- menting WPPM has been redesigned and improved. The result is a general 249 tool for nonlinear least squares ...
Project portfolio management (PPM) is a tool-supported process for optimally selecting and managing the organization's "portfolio" of projects. PPM can provide real value, but many organizations are finding implementing PPM difficult. Th... Anaheim,PP Management,EDUCAUSE,... - 《Anaheim》 被引量...
which can induce failure of the simulation. Morse bond parameters should be available from the outset to run simulations continuously and applied once the reaction has reached the desired degree of conversion. To aid in this setup, we developed a tool for Morse bond parameterization and a sample...
If Iran plans to limit its greenhouse gas concentrations up to 450 ppm equivalent to carbon dioxide based on scenario 450 [25], new eco-friendly policies should be set to safeguard the environment. Roughly one-third of the greenhouse gas emissions shared in this country are associated with the...
When the concentration of lithium-6 in tumor cells is 40 ppm, the contribution of the dose of the nuclear reaction of neutron absorption by lithium will be 55% of the total physical dose, which is sufficient for therapy with a selective accumulation of lithium in tumor cells (in the calcula...
