Predicting PV module service life

SPIE Proceedings, 2013
The International PV Module Quality Assurance Task Force was created in 2011 to develop a rating system that provides comparative information about the relative durability of PV modules. The identification of accelerated stress tests that can provide such comparative information is seen as a major step toward being able to predict PV module service ...

Potential Early Risk Biomarkers for Reduced Forced Expiratory Volume in Children Post‐Hematopoietic Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT We sought to identify potential early risk biomarkers for lung disease in children post‐allogeneic HCT. Patients with pulmonary function tests 3 months post‐transplant and plasma samples between days 7 and 14 post‐HCT were included. Six of 27 subjects enrolled had reduced forced expiratory volume 1 (FEV1) z scores.
