Method For Calculating Characteristic Frequency Ab (Rechargeable Batteries), Alisher Ganisher Ugli Bozorov

Technical science and innovation

A method for calculating the characteristic frequency is proposed, based on automatic interpolation of the frequency dependence of the reactance and subsequent calculation of the characteristic frequency as one of the roots of the interpolation function. The developed algorithm allows you to calculate the characteristic frequency from only 4 points of the frequency dependence of the reactance. In this case, the error in calculating the resonant frequency parameter does not exceed ~2 Hz.

Obviously, the values of the coefficients of the equation depend on the number of resistance values X and the corresponding frequencies of the test signal. The indicated …

Muramyl Peptide Blend Ameliorates Intestinal Inflammation And Barrier Integrity In Caco-2 Cells, Dmytro M. Masiuk, Victor S. Nedzvetsky, Giyasettin Baydas

Karbala International Journal of Modern Science

Intestinal barrier function depends on epithelial adhesion, which restricts permeability and microbial invasion from the internal environment. Impairment of barrier integrity and gut function is closely linked to pro-inflammatory changes. Inflammation is often the primary factor that provokes gut function disorders. The anti-inflammatory potential of postbiotics has been reported in recent years. Muramyl peptides (MPs) are small signaling molecules that stimulate intracellular pathogen receptors and can regulate cell responses. However, the molecular mechanisms of MPs' effects on intestinal cells remain unknown. The study of MPs treatment on lipopolysaccharide (LPS)-challenged Caco-2 intestinal cells aimed to investigate the postbiotic effects on intestinal …

Magnetized Neutral 2sc Color Superconductivity And Possible Origin Of The Inner Magnetic Field Of Magnetars, Shuai Yuan, Efrain J. Ferrer, Alejandro Pinero

Physics & Astronomy Faculty Publications

In this paper, the neutral 2SC phase of color superconductivity is investigated in the presence of a magnetic field and for diquark coupling constants and baryonic densities that are expected to characterize neutron stars. Specifically, the behavior of the charged gluons Meissner masses is investigated in the parameter region of interest, taking into account, in addition, the contribution of a rotated magnetic field. It is found that up to moderately high diquark coupling constants the mentioned Meissner masses become tachyonic independently of the applied magnetic-field amplitude, hence signalizing the chromomagnetic instability of this phase. To remove the instability, the restructuring …

Servant-Leadership, Self-Reflection, And Self-Transcendence, Ryan Schmidt

International Journal of Servant-Leadership

Whether it be income, gender, or race inequity, the gap between the haves and have-nots in the United States continues to increase, yet most people remain only concerned with themselves (Singh, 2012). Even without intention, injustice can fester. Following Robert Greenleaf’s (1977/2002) premise that caring for others is the foundation of a good society, servant-leadership provides a vision for doing the necessary inner work to achieve self-awareness before engaging with the outer work of the world. When individuals better understand the conditions governing their thoughts, feelings, and actions, the potential exists to achieve self-transcendence, re-orienting their lives outward in the …
