Sweep Optimization to Reduce Aerodynamic Loss in a Transonic Axial Compressor with Upstream Boundary Layer Ingestion [PDF]

Journal of Applied Fluid Mechanics
The aerodynamic performance of axial compressor rotors is negatively affected by the ingestion of boundary layer fluids upstream. As the boundary layer becomes thicker, the blade tip load increases and the local loss is aggravated, especially under off ...

Effect of casing treatment on performance of an inlet stage for a transonic multistage compressor [PDF]

An inlet stage of a transonic compressor was tested with three rotor tip casing treatment configurations: blade angle slots, circumferential grooves, and axial skewed slots.

Estimation and rapid identification of later stages during embryonic development of the oviparous lizard Sceloporus aeneus (Squamata: Phrynosomatidae)

The Anatomical Record, EarlyView.
Abstract Stages of embryonic development for reptiles have been presented in tables that may include all or part of embryonic development. When oviposition occurs in some lizards, embryos are already in the later stages of development; likewise, the size of the eggs increases as incubation time progresses.

Comparison of Two Fourier-Based Methods for Simulating Inlet Distortion Unsteady Flows in Transonic Compressors

Aerospace
The aerodynamic performance of transonic compressors, particularly the stall margin, is significantly influenced by inlet distortion. While time-marching methods accurately simulate such unsteady flows, they can be time-consuming.

Multi‐method analysis for the three‐dimensional reconstruction of muscle fascicles from DiceCT datasets

The Anatomical Record, EarlyView.
Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

Nanomaterial‐based immune therapeutic strategies in neurodegenerative diseases

BMEMat, EarlyView.
This review highlights the immunomodulatory potential of nanomaterials (NMs) in treating neurodegenerative diseases (NDs). It focuses on their roles in regulating innate and adaptive immune responses to maintain immune homeostasis. By providing insights into these mechanisms, the review lays the groundwork for innovative NMs therapeutic strategies to ...

Environmental Regulation at the Crossroads: A Review of Catalysts and Barriers in Circular Economy Transitions

Business Strategy and the Environment, EarlyView.
ABSTRACT Amid growing resource pressures, environmental regulation plays a critical role in enabling the transition to a circular economy (CE). This study conducts a systematic literature review to synthesize how different regulatory approaches—command‐and‐control, market‐based, voluntary, and reflexive—affect CE transitions across economic and ...
