Fluoro-copolymer contains structural element(s) of formulae (I) and (II) or 2 or structural elements (II), such that at least one element has a fluoro substituent: PB = a polymer backbone of continuous covalent carbon-carbon (C-C) bonds; Z, Z = OM or ONR4 or in one case only X...
Continual low energy malady as well as fibromyalgia-like signs or symptoms are a vital part of the phenome regarding schizophrenia: neuro-immune as well as opioid method correlates. Posted on May 8, 2025 Salmon consuming a diet containing cholesterol did not show any alteration in incremental th...
Two mathematical approaches, applied to predict the toxicity of all the possible binary equitoxic mixtures of Co, Cd, Cu, Zn and Pb, were compared to the data of their inhibition effect on V. fischeri, revealing a complex pattern of possible interactions [48]. Moreover, Cd appears much ...
Before all, a clear definition of "EDC" itself should be dis- cussed. Should the choice of a certain EDC value be determined by a certain time of reaction in a specific solution (concentration of the redox compound and redox potential)? Should the EDC include a putative fraction of elec-...
