The electrons that nature uses to reduce CO2 during photosynthesis come from water oxidation at the oxygen-evolving complex of photosystem II. Molecular catalysts have served as models understand its mechanism, in particular O–O bond-forming reaction, which is still not fully understood. Here we report a Ru(iv) side-on peroxo serves ‘missing link’ for species form after rate-determining step. (...

Abstract Background RCTs in surgery are frequently criticised because the standard to which operations performed (quality assurance - QA) is not considered during study design and delivery, risking performance bias. Lack of clarity about surgical QA may also influence successful implementation RCT results into routine practice, it unclear how procedures were undertaken. We developed measures fo...

The majority of contemporary mainstream object-oriented (OO) software is written using nominally-typed OO programming languages. Extant domain-theoretic models of OOP developed to analyze OO type systems miss crucial features of these mainstream OO languages, such as nominality. This paper summarizes the construction of NOOP as a domain-theoretic model of OOP that includes nominal information f...

This study presents the evaluation of some technological and production specifications 20 selected wild olive (oleaster) phenotypes from Hama Province, western–central Syria. The analyses oil quantity showed that (OO) extracted ranged 10.43 to 29.3%. fatty acid composition determined by gas chromatography (m/m%, methyl esters), conforming commercial standards, percentages palmitic (ranged 13.2–...

We determine the points of the epicyclic topos which plays a key role in the geometric encoding of cyclic homology and the lambda operations. We show that the category of points of the epicyclic topos is equivalent to projective geometry in characteristic one over algebraic extensions of the infinite semifield of “max-plus integers” Zmax. An object of this category is a pair (E,K) of a semimodu...

This paper proposes a novel type of Output-Output Correspondence (OO-Corr) termed Transparadigmatic Output-Output Correspondence, which I contrast against two other types of OO-Corr. This is summarized in Table 1. One is Classic OO-Corr (case studies in Benua 1997), which involves a correspondence relation between an output (candidate) [X-Y] and another output [X], which is referred to as the b...
