Beam-Induced Damage Mechanisms and their Calculation [PDF]

, 2016
The rapid interaction of highly energetic particle beams with matter induces dynamic responses in the impacted component. If the beam pulse is sufficiently intense, extreme conditions can be reached, such as very high pressures, changes of material ...

Changes in Body Composition in Children and Young People Undergoing Treatment for Acute Lymphoblastic Leukemia: A Systematic Review and Meta‐Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Ongoing evidence indicates increased risk of sarcopenic obesity among children and young people (CYP) with acute lymphoblastic leukemia (ALL), often beginning early in treatment, persisting into survivorship. This review evaluates current literature on body composition in CYP with ALL during and after treatment.

Impact of temperature and humidity on the thermal decomposition behavior and the ignition characteristics of Si-based pyrotechnic delay composition

FirePhysChem
This study focuses on analyzing the degradation, ignition, and combustion behavior of a silicon (Si)-based pyrotechnic delay mixture. A comparative analysis is conducted between a fresh sample and one exposed to accelerated aging conditions at a constant
