On the Integrability of Supersymmetric Versions of the Structural Equations for Conformally Parametrized Surfaces
The paper presents the bosonic and fermionic supersymmetric extensions of the
structural equations describing conformally parametrized surfaces immersed in a
Grasmann superspace, based on the authors' earlier results. A detailed analysis
of the symmetry properties of both the classical and supersymmetric versions of
the Gauss-Weingarten equations is performed. A supersymmetric generalization of
the conjecture establishing the necessary conditions for a system to be
integrable in the sense of soliton theory is formulated and illustrated by the
examples of supersymmetric versions of the sine-Gordon equation and the
Gauss-Codazzi equations
Modeling of the oxygen transfer in the respiratory process
International audienceIn this article, we propose an integrated model for oxygen transfer into the blood, coupled with a lumped mechanical model for the ventilation process. We aim at investigating oxygen transfer into the blood at rest or exercise. The first task consists in describing nonlinear effects of the oxygen transfer under normal conditions. We also include the possible diffusion limitation in oxygen transfer observed in extreme regimes involving parameters such as alveolar and venous blood oxygen partial pressures, capillary volume, diffusing capacity of the membrane, oxygen binding by hemoglobin and transit time of the red blood cells in the capillaries. The second task consists in discussing the oxygen concentration heterogeneity along the path length in the acinu
BiocharFX: Production with carbonFX technology, characterization and applications in potting soil related to plant production
Airex Energy started its R&D activities on torrefaction technology in 2010 and has been operating the first and only commercial-scale biocoal plant in Canada since 2015. The company has developed the patented CarbonFXTM process for biomass torrefaction. The biochar produced from this technology can be used for different applications, one of them being as a soil amendment. The biochar produced by Airex Energy is called BiocharFXTM. In Canada, the use of biochar as a soil amendment for agriculture, horticulture or mixed with other porous media, requires a certification from the Canadian Food Inspection Agency.
