THE SINGLE-PHASE TRANSFORMER AS A SOURSE OF CURRENT HARMONICS
Dynamics of Systems, Mechanisms and Machines, 2017 The aim of the paper is to calculate the maximum magnetic induction value of the transformer's core which provides a specified value of current distortion. To solve this problem, an experimental study was made on the dependence of the magnetic induction on Total Harmonic Distortion for current.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

THE RESEARCH ON SPECIAL ELECTRONIC POWER TRANSFORMER
Electrica, 2009 In many circumstances, three-phase AC power supply is not always the best choice for utility applications. In fact, there is a rating of three-phase to single-phase, three-phase to dual-phase and three-phase to multiphase transformers being in operation ...

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Identification of Transformer Parameters Using Dandelion Algorithm
Applied System InnovationResearchers tackled the challenge of finding the right parameters for a transformer-equivalent circuit. They achieved this by minimizing the difference between actual measurements (currents, powers, secondary voltage) during a transformer load test and ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
