PDC-109 is the prevalent secretory protein from bovine seminal vesicles that binds to the midpiece of sperm once they pass the ampulla of the vas deferens during emission. Thereby, the protein changes biophysical membrane properties, eventually resulting in increased sperm motility. To elucidate the underlying biochemical mechanism, we have studied the ion-pumping activity (Ca(2+)-ATPase) in me...

A low carbon, high efficiency and high quality power supply scheme for Distributed Generation (DG) in a micro-grid is presented. A three-phase, four-leg DG grid-interfacing converter based on the improved structure of a Unified Power Quality Conditioner (UPQC, including a series converter and a parallel converter) is adopted, and improved indirect and direct control strategies are proposed. It ...

PDC (pyruvate dehydrogenase complex) is a multi-enzyme complex comprising an E1 (pyruvate decarboxylase), an E2 (dihydrolipomide acetyltransferase) and an E3 (dihydrolipoamide dehydrogenase). PDC catalyses the decarboxylation of pyruvate and forms acetyl-CoA and NADH. In the human malaria parasite Plasmodium falciparum, the single PDC is located exclusively in the apicoplast. Plasmodium PDC is ...

The asymmetric unit of the title heterometallic coordination polymer, [Cu(3)Eu(2)(C(7)H(3)NO(4))(6)(H(2)O)(6)](n), contains one Eu(III) and two Cu(II) atoms, three pyridine-2,4-dicarboxylate (pdc)(2-) anions and three water molecules. One Cu(II) atom is located on an inversion center and is N,O-chelated by two pdc(2-) anions in the equatorial plane and further coordinated by two carboxyl-ate O ...

This document deals with the problem of passive fuzzy controller design state-derivative feedback approach for nonlinear stochastic singular systems. Recently, systems have a greater focus on literature because they can keep more physical system characteristics than conventional At first, Takagi-Sugeno models are used to represent Then, and parallel distributed compensation method employed cont...

A model reference adaptive control method is proposed for uncertain nonlinear characteristics of spacecraft attitude control system. This method combines fuzzy control methodology and nonlinear feedback linearization methodology, which made the closed-loop system stable and the state of fuzzy system track the state of reference model according to the parallel distributed compensation theory and...
