В§Simplifies the strict process of вЂњneutron flux-activation calculation-residual doseвЂќ calculation by using highly visible geometry arrays and keeping control of the whole calculation process without the risks of вЂњblack boxвЂќ use of other solutions. Highly specialized in the analysis of radiation transport problem by the use of three-dimensional Monte Carlo tools, mainly MCNP (Monte Carlo N-Particle) family of codes.

The wide experience with the use of MCNP and ACAB (Activation Abacus Code) codes allows the creation and easy use of this program instead of the long processing times of automated routines using MCNP+FISPACT (inventory code capable of performing modelling of activation, transmutations and depletion induced by neutron, proton, alpha, deuteron or gamma particles incident on matter). It is being used in metallic components inside fission reactor vessel and inside reload cavity during dismantling operations.

The process of automation and residual dose calculation may take 1 hour for a 15 layers case of such 50Г—50 voxels array. It also provides the source distribution of photons produced in the decay of such nuclides and calculate the dose around the structure produced by the different nuclides. It decomposes the 3D geometry in a set of layers of approximately 50Г—50 voxels and allows using the energy-detailed neutron flux in these voxels to determine the activity of nuclides of interest at each layer.

The technology consists in a software which automates the process of calculation of neutron activation of a structure or component and the residual dose around this structure or component. 3, pp.DOWNLOAD THE TECHNOLOGY DESCRIPTION Description of the Technology

Journal: Journal of Alzheimer's Disease, vol. Keywords: Aging, AlzheimerвЂ™s disease, dementia, memory, neuropsychology This study highlights the utility of considering interactions between dementia risk factors and a patientвЂ™s unique cognitive history. Conclusion: The finding that different risk factors for LOAD were associated with specific memory trajectories may reflect the existence of resilience or vulnerability factors that modify the individual influences of risk/protective factors. Results: Predictors of incident dementia differed across trajectory groups: older age only incurred independent risk in stable groups, education did not incur independent protection in the rapidly declining group, depression only incurred independent risk in the stable-low group, stroke incurred independent risk in the two extreme groups, and APOE-Й›4 only incurred independent risk in the rapidly declining group. Participants included 2,593 racially/ethnically diverse older adults (mean age of 76 at study entry) in the Washington Heights-Inwood Columbia Aging Project. Methods: Risk factors for incident LOAD were compared across previously-validated groups of older adults exhibiting different memory trajectories (вЂњStable-High,вЂќ вЂњStable-Low,вЂќ вЂњDecliner,вЂќ вЂњRapid DeclinerвЂќ) using stratified Cox regressions. This line of research may lead to more individualized risk profiles. Objective: Th is study examined how dementia risk factors differ across subgroups of older adults defined by memory trajectory. However, it is not known whether these risk and protective factors differ for individuals who are cognitively stable versus those already experiencing declines. ДЄbstract: Background: Previous research has identified multiple risk and protective factors for late onsetВ AlzheimerвЂ™s disease (LOAD).
