Abstract The paper describes a theoretical study and exploration of authors in the field biomechanics. lung parenchyma is focused, its elastic behaviour under physiological mechanical load, pressure change during breathing. Anatomical view to human respiratory system generally introduced first together with more detailed description alveolus. Then appropriate theory elaborated, aimed on mathema...

Using a new NMR correlation-peak imaging technique, we were able to investigate noninvasively the spatial distribution of carbohydrates and amino acids in the hypocotyl of castor bean seedlings. In addition to the expected high sucrose concentration in the phloem area of the vascular bundles, we could also observe high levels of sucrose in the cortex parenchyma, but low levels in the pith paren...
