Titanium Aluminide (TiAl) alloys are intermetallics that offer low density, high melting point, good oxidation and corrosion resistance compared to Ni-based superalloys.As a result, these alloys are used in aero-engine parts such as turbine blades, fuel injectors, radial diffusers, divergent flaps, and more.During operation, aero-engine components
The study aimed to investigate the impact of posterior element and ligament removal on the maximum von Mises stress, and maximum shear stress of the eight-layer annulus for treating stenosis at the L3-L4 and L4-L5 levels in the lumbar spine.Previous studies have indicated that laminectomy alone can result in segmental instability unless fusion is p
This study aimed Mobiles to assess the current land data acquisition system, data sharing mechanism and major challenges in Ethiopia.A total of 26 institutions working mainly on land data collection, management, dissemination, and use were purposively selected.Data were collected from these institutions using face-to-face interviews, focus group di
HTTP-based video streaming technology is DRY/DAMAGED CONDITIONER widely used in today’s video delivery services.The streaming solution uses the adaptive bitrate (ABR) algorithm for better video quality and user experience.Despite many efforts to improve the quality of experience (QoE), it is very challenging for ABR algorithms to guarantee h
Abstract Background Developmental pluripotency-associated 3 (Dppa3, also called Stella or PGC7) is a principal maternal protein specially expressed in pre-implantation embryos, embryonic stem cells (ES cells) and primordial germ cells (PGCs).It plays critical role in the regulating of DNA methylation in zygotes and oocytes.However, the effect of Dp
