In oxygenic photosynthetic organisms the PSI-C polypeptide, encoded by the psaC gene, provides the ligands for two [4Fe-4S] centers, FA and FB, the terminal electron acceptors in the photosystem I (PSI) complex. An insertion mutation introduced in the psaC locus of the filamentous cyanobacterium Anabaena variabilis ATCC 29413 resulted in the creation of a mutant strain, T398-1, that lacks the P...

By employing the convolution theorem of Laplace transforms, some asymptotic formulas and integral representations of the gamma, psi and polygamma functions, and other analytic techniques, this note provides an alternative proof of a monotonicity and convexity property by N. Elezović, C. Giordano and J. Pečarić in [4] to establish the best bounds in GautschiKershaw inequalities. Moreover, some (...
