The Anatomical Record, EarlyView.This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Numerical Simulation of Turbulence Flows in Shear Layer
Archives of Metallurgy and Materials, 2014 For various problems of continuum mechanics described by the equations of hyperbolic type, the comparative analysis of scenarios of development of turbulent flows in shear layers is carried out.

AN IMPROVED TURBULENCE MODEL FOR ROTATING SHEAR FLOWS
Proceeding of Second Symposium on Turbulence and Shear Flow Phenomena, 2001 In the present study, we construct a turbulence model based on a low-Reynolds-number non-linear k–ϵ model for turbulent flows in a rotating channel. Two-equation models, in particular the non-linear k–ϵ model, are very effective for solving various flow ...

Effective pretreatment of wet microalgal biomass to enhance lipid extraction in biodiesel production
Biofuels, Bioproducts and Biorefining, EarlyView.Abstract Biodiesel is a viable alternative to fossil fuels. Identifying and evaluating nonedible sources is essential to address ecological concerns and meet energy demands. Microalgae are effective for lipid production but their rigid cell walls hinder bioproduct release making the process energy‐intensive and costly.

Turbulence lifetimes: what we can learn from the physics of glasses
, 2012 In this note, we critically discuss the issue of the possible finiteness of the turbulence lifetime in subcritical transition to turbulence in shear flows, which attracted a lot of interest recently.

Psilocybin Production With Genetically Modified Aspergillus nidulans Under Pressurized Conditions
Biotechnology and Bioengineering, EarlyView.Shake flask cultures of psilocybin‐producing A. nidulans were investigated with respect to nitrogen source, rheology, power input, and oxygen availability, and subsequently scaled to a stirred tank reactor scale based on specific power input to develop and optimize a pressurized bioprocess.

Inflectional instabilities in the wall region of bounded turbulent shear flows [PDF]
The primary thrust of this research was to identify one or more mechanisms responsible for strong turbulence production events in the wall region of bounded turbulent shear flows.

Hydrogel Embedding of Mesenchymal Stem Cells Supports Extracellular Vesicle Production
Biotechnology and Bioengineering, EarlyView.This study investigates the effects of 3D culture conditions on extracellular vesicle (EV) production by mesenchymal stem cells (MSCs) in a gelatin‐based hydrogel matrix (GelMA). The EVs from both conditions were found to have similar morphological, molecular, and functional properties, but 3D cultures produced more total EVs per volume.
