In this work we study the Zeeman effect on stratospheric O2 using ground-based microwave radiometer measurements.The interaction of the Earth magnetic field with the oxygen dipole leads to a splitting of O2 energy states, which polarizes the emission spectra.A special campaign was carried out in order to measure this effect in the oxygen emission l
Strain-based design (SBD) plays an important role in pipeline design and assessment of pipelines subjected to geo-hazards.Under such hazards, a pipe can oliver peoples forman r be subjected to substantial plastic strains, leading to tensile failure at locations of girth weld flaws.For SBD, the finite element method (FEM) can be a reliable tool to c
Liver inflammation, injury, and hepatic cell death are caused by external agents (viruses, bacteria, drugs, alcohol, etc.) along with the genetic susceptibility of an individual.Persistent activation of the fibrogenic response in cells leads to liver fibrosis which in turn progresses to cirrhosis and cancer.The dysregulation of the immune system ge
The numerical assessment of reconstructed aortic valves competence and leaflet design optimization rely on both coaptation characteristics and the diastolic valve configuration.These characteristics can be evaluated by the shell or membrane formulations.The membrane formulation is preferable for surgical aortic valve neocuspidization planning since
Introduction.The basic theoretical and methodological approaches to the study of the social well-being of the population of megacities as an integral indicator, as well as current trends in the development of new diagnostic methods are considered.The experience of empirical sociological research is presented, showing methodological algorithms for s
