A physiological model of softwood cambial growth.
Cambial growth was modelled as a function of detailed levelled physiological processes for cell enlargement and water and sugar transport to the cambium. Cambial growth was described at the cell level where local sugar concentration and turgor pressure induce irreversible cell expansion and cell wall synthesis. It was demonstrated how transpiration and photosynthesis rates, metabolic and physio...
متن کاملWoodification: User-Controlled Cambial Growth Modeling
We present a botanical simulation of secondary (cambial) tree growth coupled to a physical cracking simulation of its bark. Whereas level set growth would use a fixed resolution voxel grid, our system extends the deformable simplicial complex (DSC), supporting new biological growth functions robustly on any surface polygonal mesh with adaptive subdivision, collision detection and topological co...
متن کاملGrowth Processes Induced by Estrogenic Hormones
In former investigations we have studied the growth processes which take place in the mammary gland ( 1 j and in the vagina and cervix ( 2 ) of mice under the 'influence of estrogenic hormones, and the conditions under which these .processes become cancerous. The investigations recorded here extend this analysis to the uterus of the mouse. By uterus, we understand that part of the vaginal-cervi...
متن کاملGrowth and Optical Properties Investigation of Pure and Al-doped SnO2 Nanostructures by Sol-Gel Method
SnO2 nanoparticles with different percentage of Al (5%, 15%, and25%) were synthesized by sol-gel method. The structure and nature of nanoparticles are determined by of X-ray diffraction analysis. Also, morphology of the samples is evaluated by SEM. Moreover, the optical properties of the samples are investigated with UV-Visible and FT-IR. The XRD patterns are in...
متن کاملActivation and inhibition of adenylate cyclase by hormones.
Basic features of the hormone-dependent adenylate cyclases The adenylate cyclase system is composed of three basic units (Ross & Gilman, 1980): the receptor R facing the outside of the cell and binding the hormone or neurotransmitter, the GTP regulatory unit N (or G/F), and the catalytic unit C. Both N (G/F) and C face the cytoplasm and react with GTP and MgATP2respectively. Hormone binding to ...
