Article Synopsis
- Researchers are exploring a method to lower the cost of III-V solar cells by detaching them from their growth substrate, allowing for the reuse of the substrate to produce multiple cells.
- The study focuses on smoothing the faceted surfaces left on GaAs(100) substrates after spalling to enable the growth of high-quality solar cells.
- The smoothing process can be influenced by the choice of epilayer material and the introduction of impurities or dopants, which significantly affect the smoothness and rate of surface improvement.
Article Synopsis
- A 20-year-old man with a complex medical history involving Legg-Calve-Perthes disease and hip issues underwent multiple surgeries including arthroscopic femoroplasty and allografting.
- The procedures aimed to repair fragmented bone and improve hip function, culminating in a valgus-producing derotational femoral osteotomy and periacetabular osteotomy.
- At the one-year follow-up, the patient showed complete healing of the femoral head and successfully returned to his active lifestyle, marking a first in the use of arthroscopic allografting for this condition.
Background: Non-compressible abdominal hemorrhage (NCAH) is the leading cause of potentially preventable deaths in both civilian and military austere environments, and an improvement in mortality due to this problem has not been demonstrated during the past quarter century. Several innovations have been developed to control hemorrhage closer to the point of injury.
Objective: This review assessed NCAH interventions in civilian and military settings, focusing on austere environments.
Sprint and jump performances represent performance-determining parameters in individual and team sports. Fluctuations in performance depending on the daytime raise the question of the best time to train and compete. Given the scarce research on females, this study aimed to analyze the influence of daytime on sprint and jump performances and to investigate whether the performance difference is related to the chronotype.
