Developing earth-abundant, active and stable electrocatalysts which operate in the same electrolyte for water splitting, including oxygen evolution reaction and hydrogen evolution reaction, is important for many renewable energy conversion processes. Here we demonstrate the improvement of catalytic activity when transition metal oxide (iron, cobalt, nickel oxides and their mixed oxides) nanopar...

let φ be a w  -continuous homomorphism from a dual banach algebra to c. the notion of φ-connes amenability is studied and some characterizations is given. a type of diagonal for dual banach algebras is dened. it is proved that the existence of such a diagonal is equivalent to φ-connes amenability. it is also shown that φ-connes amenability is equivalent to so-called φ-splitting of a certain s...

Nucleosome deposition occurs on newly synthesized DNA during DNA replication and on transcriptionally active genes via nucleosome-remodeling complexes recruited by activator proteins and elongating RNA polymerase II. It has been long believed that histone deposition involves stable H3-H4 tetramers, such that newly deposited nucleosomes do not contain H3 and H4 molecules with their associated hi...

Abstract. The problem of splitting a homotopy equivalence along a submanifold is closely related to the surgery exact sequence and to the problem of surgery of manifold pairs. In classical surgery theory there exist two approaches to surgery in the category of manifolds with boundaries. In the rel ∂ case the surgery on a manifold pair is considered with the given fixed manifold structure on the...

Staged programming languages assign a stage to each program expression and evaluate each expression in its assigned stage. A common use of staged languages is to describe programs where inputs arrive at different times or rates. In this paper we present an algorithm for statically splitting these mixed-staged programs into two unstaged, but dependent, programs where the outputs of the first pro...

The electron spin resonance (ESR) spectra of 15NOand 14NO-ligated Hb Kansas have been measured at 77 K in the range of pH 5 to 10. At low pH the ESR spectrum is the composite of a type I and a type II spectrum which changes to another composite of a type I and type II spec­ trum at high pH. For the definition of type I and type II spectra and the correlation of these types with two tertiary con...

In this study, we implemented the different approaches to compare their time efficiency. MMB-FCA, EFP-FCA and FCF are the previous approaches which were (re-)implemented in this study. Additionally, our new method called FFCA, together with three improved versions of the FCF method, namely W-FCF (FCF without splitting reversible reactions), WR-FCF (FCF without splitting reversible reactions and...

Due to the rapid development of industrialization, recycling and utilization industrial by-products have received extensive attention. In this paper, binary, ternary, quaternary composite cementitious materials were prepared using steel slag, blast furnace fly ash, effects different on concrete properties explored. A variety solid wastes mixed, batches with high mechanical durability by adjusti...

background: the aim of this study was to evaluate the efficacy of arterial blood gases (abgs) in determining the type of intoxication. methods: medical charts of all patients who had referred to the toxicology ward of baharloo hospital between january 2009 and december 2009 were evaluated. after excluding the patients with multi-drug toxicity, data, including age, sex, type of intoxication (the...
