hydrogen as an ideal energy carrier can play a very important role in future energy systems for hydro-gen production can be used a variety of technologies and sources. one of the most promising methods for large-scale hydrogen production is thermo-chemical water decomposition using heat energy from nuclear, solar and other sources. the water splitting thermo-chemicals cycles are processes where...

Background: To assess whether Bromocriptine Rebound Method (BRM), can improve pregnancy outcomes after intracytoplasmic sperm injection (ICSI) cycles. Materials and Methods: In this prospective study, we analyzed data from a total of 117 women who underwent ICSI cycles. Pregnancy outcomes and hormonal data were compared between long protocol and BRM groups. Ovulatory women with normal serum pro...

We characterize the distributions of short cycles in a large metabolic network previously shown to have small world characteristics and a power law degree distribution. Compared with three classes of random networks, including Erdős-Rényi random graphs and synthetic small world networks of the same connectivity, both the metabolic network and models for the chemical reaction networks of planeta...

Approach • Review all published papers, reports, patents, etc. in the past 25+ years that relate to thermochemical water-splitting cycles, in general, and solar driven cycles, in particular. • Use FactSageTM program to perform chemical equilibrium calculations. • Employ HYSYS/ASPEN Plus chemical process simulation (CPS) program for developing process flowsheet, process analyses and optimization...

BACKGROUND Cycles of covalent modification are ubiquitous motifs in cellular signalling. Although such signalling cycles are implemented via a highly concise set of chemical reactions, they have been shown to be capable of producing multiple distinct input-output mapping behaviours - ultrasensitive, hyperbolic, signal-transducing and threshold-hyperbolic. RESULTS In this paper, we show how th...

  Purpose: To assess whether bromocriptine-rebound method (BRM) can improve pregnancy   outcomes compared to long protocol after intracytoplasmic sperm injection cycles (ICSIs).   Materials and Methods: A total of 114 women underwent ICSI. Pregnancy outcomes and   hormonal data were compared between two groups, i.e. long protocol and BRM. Ovulatory   women with normal serum prolactin levels wer...
