Physical-Mechanical Properties of Superhard Nanocomposite Coatings on Base Zr-Ti-Si-N

Medžiagotyra, 2013
Hard and super hard coatings of Zr-Ti-Si-N of from 2.8 μm to 3.5 μm thickness were fabricated using a vacuum arc source with high frequency stimulation. The samples were annealed in vacuum and in air at 1200 °C. It was found that films with a high Zr and

Guidelines for Pediatric Radiotherapy Simulation: A Report From the Children's Oncology Group Radiation Oncology Discipline

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric radiation therapy presents unique challenges compared to adult treatments, including those of immobilization, potential need for sedation, and the critical importance of accurate, reproducible positioning. Additionally, heightened attention to imaging doses is necessary to minimize long‐term toxicity in survivors.

Biochips: Focusing on Surfaces and Surface Modification

, 2004
Thousands of genes and their products (i.e., proteins) in a given living organism function in a complicated and orchestrated way that creates the mystery of life. In “genomics”, briefly genes of organisms, their functions and activities are investigated.
