Predictive Formula For Electron Range Over A Large Span Of Energies, Anne C. Starley, Gregory Wilson, Lisa Montierth Phillipps, Jr Dennison

A model has been developed to predict the approximate penetration depth into diverse classes of materials for a broad range of energetic incident electrons (<10 eV to >10 MeV, with better than 20% accuracy). The penetration depth—or range—of a material describes the maximum distance electrons can travel through a material, before losing all of its incident kinetic energy. This model leads to a predictive formula that estimates the penetration depth for materials without the need for supporting data, but rather using only basic material properties and a single fitting parameter (Nv, described as the effective number of valence electrons). Nv …10>

The penetration range of energetic electrons into diverse materials can be modeled approximately with a simple fit. This fit is a function of a single parameter, Nv, which describes the effective number of valence electrons. Using the Continuous-Slow-Down-Approximation (CSDA) for energy deposition in a material, a composite analytical formula has been developed which estimates the range or maximum penetration depth of incident electrons for energies from10 MeV with an uncertainty of

Introduction:
Most congenital heart disease [CHD] is diagnosed and treated in early childhood with parents responsible for decision-making. The adolescent assumes this role in preparation for transition to an adult congenital heart program. We studied the knowledge base of our adolescent CHD patients and their parents.
Methods:
Established CHD patients, >11 y.o. and their parents, were independently surveyed in the outpatient clinic. Participation was voluntary. Cardiomyopathy, electrophysiology and transplant patients were excluded. Scores were assessed as full, partial or incomplete.
Results:
Most (98% parents; 83% adolescents) reported that their cardiologist had provided education. Adolescents provided a full (49%) and partial …

Background:
Studies have reported a knowledge gap Studies have reported a knowledge gap among adolescent and young adult heart heart transplant patients upon transitioning to adult cardiology practices.
This population is vulnerable to life-threatening complications as they progress to adult care.
Framework/Methods:
We assess the current knowledge deficit of our adolescent and young adult patients and their caregivers in order to inform pediatric providers of their unique needs as they prepare to transition.
Heart transplant patients >10 yrs and their caregivers completed a written questionnaire prior to a clinic visit. 17 questions were asked including the need for …
