Entropy Generation Analysis due to Permeable Exponential Stretching in Boundary Layer Flows

Heat Transfer, EarlyView.
ABSTRACT Entropy generation represents the irreversible loss of useful energy in thermal–fluid systems, directly reducing efficiency in applications, such as microelectronics cooling, nanofluid‐based heat exchangers, and polymer processing. This study investigates entropy generation in a two‐phase viscoelastic nanofluid flow over a permeable ...

Alcohol Septal Ablation in Hypertrophic Obstructive Cardiomyopathy: Long‐Term Follow‐Up of Deformations and Hemodynamics

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background A detailed evaluation of hemodynamics, supportive morphology, and deformation may help uncover the pathophysiology of hypertrophic obstructive cardiomyopathy (HOCM) and the changes wrought by alcohol septal ablation (ASA). Purpose To investigate the global cardiac volume, myocardial deformation, and hemodynamic characteristics ...

Sub-Alfvénic Turbulence: Magnetic-to-kinetic Energy Ratio, Modification of Weak Cascade, and Implications for Magnetic Field Strength Measurements

The Astrophysical Journal
We study the properties of sub-Alfvénic magnetohydrodynamic (MHD) turbulence, i.e., turbulence with Alfvén mach number M _A = V _L / V _A < 1, where V _L is the velocity at the injection scale and V _A is the Alfvén velocity.

Precision Restoration to Minimize Soil Loss in a Watershed in the Atlantic Forest Domain

Land Degradation &Development, EarlyView.
ABSTRACT The Turvo River Watershed, located in the Zona da Mata region of Minas Gerais and part of the Doce River Basin, faces serious problems of erosion and soil degradation, which compromise and reduce the quality of local water resources. Given this scenario, it is essential to implement environmental recovery strategies that prioritize the ...

Analysis of Turbulence and Turbulence Kinetic Energy Dynamics in Complex Terrain

Journal of Geophysical Research: Atmospheres
AbstractBoundary layer processes and turbulence in a complex terrain are influenced by thermally driven flows, as well as dynamically forced flows when ambient wind interacts with orography. This paper investigates the variability in turbulence kinetic energy (TKE) with elevation and topography in a shallow high mountain valley in the Canadian Rockies.

Impact of Formulation Ingredient Compatibility on Encapsulation of Hydrophobic Substances in Polymeric Nanocarriers Prepared by Nanoprecipitation

Macromolecular Materials and Engineering, EarlyView.
Encapsulation of hydrophobic drugs in poly(lactic‐co‐glycolic) acid (PLGA) nanoparticles strongly depends on solvent and polymer compatibility. By linking Hansen solubility parameters with atomic force microscopy (AFM), scanning electron microscopy (SEM), and differential scanning calorimetry (DSC) analyses, the work reveals predictive markers of ...

An energy-constrained profile parameterization of shear-driven turbulence in the interior ocean

Frontiers in Marine Science
This paper proposes an energy-constrained profile parameterization of both turbulent kinetic energy dissipation rate (ϵ) and vertical diffusivity (κ), for shear instability-induced turbulence that is initiated in an initial unstable layer (IUL) where the

Thermometer Ions, Internal Energies, and In‐Source Fragmentation in Ambient Ionization

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Ionization and fragmentation are at the core of mass spectrometry. But they are not necessarily separated in space, as in‐source fragmentation can also occur. Here, we survey the literature published since our 2005 review on the internal energy and fragmentation in electrospray ionization sources.
