Chemical genesis

One should note overall, that while some of these suggested mechanisms may in the future prove to have a role in the control of smooth muscle contraction, in chemically skinned preparations maximum force development follows activation by the MLCK active subunit in extremely low Ca " ion concentrations. The conclusion can hardly be avoided that phosphorylation alone is sufficient for activation, and if another mechanism is involved, it is not necessary for the initial genesis of force. If such mechanisms are operative, then they might be expected to run in parallel or consequent to myosin phosphorylation. A possible example of this category of effect is that a GTP-dependent process (G-protein) shifts the force vs. Ca ion concentration relationship to lower Ca ion concentrations. This kind of mechanism calls attention to the divergence of signals along the intracellular control pathways. 

Further dramatic changes can happen in chemical reactivities of gold clusters with diameters smaller than 2nm. The contribution of support materials including metal oxides, carbons, and polymers to the genesis of unique catalytic properties may be much greater than in the case of NPs and therefore may provide an expanding new field of research.

The genesis of signals is directly connected with the interaction between the entities of the sample (see Fig. 2.13) and the form of matter and energy represented in Fig. 3.2. This interaction produces the signal as a result of a chemical reaction, an electrochemical, physicochemical or physical process, e.g. by a neutralization or precipitation reaction, an electrolytical process, or by interactions between radiation and particles on the one hand and the sample species on the other. 

Going further even than Muir, some eminent chemists stridently opposed modem alchemy and the transmutation hypotheses emerging to explain radioactivity. Toward the end of his life, Mendeleev, for example, became quite concerned about the implications of radioactivity for his scientific and chemical world view. As Michael Gordin explains, Mendeleev s most salient exposure to radioactivity, and the genesis of most of his hostile views of the phenomenon, was his visit to the Curies laboratory in Paris in 1902. What he saw evoked similar worries as the Spiritualists had. He wrote in his Paris notebook ... [M]ust one admit whether there is spirit in matter and forces Radio-active substances, spiritualism (Gordin 2004,213). Mendeleev...

The chemical and isotopic compositions of various earth materials now make up the data used to build models to explains the formation of the Earth, its evolution the genesis of the different terrestrial units continents, mantle, core, ocean etc.. .. From a descriptive and qualitative early stage, geochemistry has become explanatory and quantitative. In this new context modeling is a key method.
