Conditions for Stable Equilibrium of the Upright Human Body in the Absence and Presence of External Influence

Authors: Karlo Moistsrapishvili
Comments: 10 Pages. -

Introduction: This paper combines two previous scientific works [1, 2]. It investigates conditions of the equilibrium stability of a cylinder (shaped homogeneous body) in order to study the equilibrium stability of a human body of different proportions. A new method to determine a human body’s common center of gravity is proposed. An optimal bending forward angle at which the degree of the equilibrium stability of an upright standing person reaches its maximum value is defined and relevant conclusions are drawn. In addition, external forces are also introduced, which may disturb the stable equilibrium and cause the body to tumble. The paper also introduces the concept of the coefficient of the stable equilibrium and proposes a formula for its calculation. Finally, a formula is set up to obtain the maximum value of external forces under which the body still maintains the state of equilibrium. Key words: equilibrium stability; common center of gravity; optimal bending; critical angles, stability coefficient, force of gravity, external force, overturning.

Relationship Between Liquid-Liquid Phase Separation and Epigenetic Modification Based on the Boltzmann Distribution

Authors: Fei Xiong
Comments: 9 Pages.

Liquid-liquid phase separation is pervasive in the interior of cells. Elucidating the mechanism of its formation is important both for understanding its physiological function and for predicting prospective drug targets. According to the Boltzmann distribution, we describe a physical relationship between liquid-liquid phase separation and epigenetic modification, suggesting that biochemical metabolism may play an important role in phase separation. It also suggests that liquid-liquid phase separation is universal in the origins of early life because alkaline hydrothermal vents are full of biochemical reactions.

Masks Don’t Work: a Review of Science Relevant to Covid-19 Social Policy

Authors: Denis G. Rancourt
Comments: 13 Pages.

Masks and respirators do not work. There have been extensive randomized controlled trial (RCT) studies, and meta-analysis reviews of RCT studies, which all show that masks and respirators do not work to prevent respiratory influenza-like illnesses, or respiratory illnesses believed to be transmitted by droplets and aerosol particles. Furthermore, the relevant known physics and biology, which I review, are such that masks and respirators should not work. It would be a paradox if masks and respirators worked, given what we know about viral respiratory diseases: The main transmission path is long-residence-time aerosol particles (< 2.5 μm), which are too fine to be blocked, and the minimum-infective-dose is smaller than one aerosol particle. The present paper about masks illustrates the degree to which governments, the mainstream media, and institutional propagandists can decide to operate in a science vacuum, or select only incomplete science that serves their interests. Such recklessness is also certainly the case with the current global lockdown of over 1 billion people, an unprecedented experiment in medical and political history.

Unique Relation Between Human Muscle's Force and the Muscle's Weight

Authors: Yahya A. Sharif
Comments: 2 Pages.

The force used by muscles to lift itself is smaller than the muscles weight in which small muscles force can lift its huge mass.An example is someone lifts his massive 60 kg body with weak feet and calfs muscles when trying to pick a fruit from a tree.
