The midpoint potential of the [2Fe-2S] cluster of the Rieske iron-sulfur protein (Em7 = +280 mV) is the primary determinant of the rate of electron transfer from ubiquinol to cytochrome c catalyzed by the cytochrome bc1 complex. As the midpoint potential of the Rieske cluster is lowered by altering the electronic environment surrounding the cluster, the ubiquinol-cytochrome c reductase activity...

We give an analytic proof for the Hausdorff convergence of the midpoint or derived polygon iteration. We generalize this iteration scheme and prove that the generalization converges to a region of positive area and becomes dense in that region. We speculate on the centroid or derived polyhedron iteration.

we derive whole series of new integral inequalities of the hardy-type, with non-conjugate exponents. first, we prove and discuss two equivalent general inequa-li-ties of such type, as well as their corresponding reverse inequalities. general results are then applied to special hardy-type kernel and power weights. also, some estimates of weight functions and constant factors are obtained. ...

A raster-based algorithm for drawing circles is derived by using the so-called assertion-guided approach to program construction. The initially derived form is slightly different from published ones. It can, however, be transformed into the secondorder midpoint circle-drawing algorithm. Because of the rigour of the approach, the correctness of the derived algorithm is assured. The approach also...

in this paper, the non-linear dynamic response of novel steel sandwich panel with hollow i-core subjected to blast loading was studied. special emphasis is placed on the evaluation of midpoint displacements and energy dissipation of the models. several parameters such as boundary conditions, strain rate, mesh dependency and asymmetrical loading are considered in this study. the material and geo...

BACKGROUND AND OBJECTIVES The precise location of the adductor canal remains controversial among anesthesiologists. In numerous studies of the analgesic effect of the so-called adductor canal block for total knee arthroplasty, the needle insertion point has been the midpoint of the thigh, determined as the midpoint between the anterior superior iliac spine and base of patella. "Adductor canal b...
