By‐product of heparin extraction as a sustainable alternative to enhance the use of nitrogen in agriculture

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract This study evaluates the potential of a new organic fertilizer derived from porcine intestinal mucosa (designated BHE), a by‐product of the heparin extraction process, as a sustainable nitrogen (N) source for agriculture. The work was conducted in two stages: (i) chemical and spectroscopic characterization of BHE compared with poultry litter ...

Mutation type‐specific transcriptomic signatures and readthrough therapy rescue in SMC1A‐related developmental and epileptic encephalopathy

open access: yesEpilepsia, EarlyView.
Abstract Objective This study was undertaken to investigate the molecular consequences of pathogenic variants in the SMC1A gene—particularly those associated with developmental and epileptic encephalopathy (DEE85)—and to evaluate the therapeutic potential of ataluren in restoring SMC1A function and mitigating disease‐related transcriptomic and genomic ...

Design of HAWT Rotor for Non‐Uniform Inflow Conditions: A Theoretical and Experimental Approach for Shear Flow

open access: yesEnergy Science &Engineering, EarlyView.
This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

Two‐Layer Optimal Control Strategy of Thermal Power Unit Coupled With Hybrid Energy Storage System in Frequency Regulation

open access: yesEnergy Science &Engineering, EarlyView.
An optimized two‐layer TPU‐HESS operation strategy enables adaptive power allocation, mitigates regulation delay, and enhances AGC performance by 6.4% over conventional control methods. ABSTRACT With the growing penetration of renewable energy, its intermittency and fluctuation have imposed increasingly stringent regulation requirements on thermal ...
