A hybrid method based on the structural equation model (SEM) and a fuzzy cognitive map (FCM) was developed to study influences of construction safety risks (CSR) metro tunnels constructed by mining project risk (PR). An SEM used identify verify correlations between CSR PR. FCM adopting verified standardized causality path coefficient in SEM. On this basis, predictive reasoning diagnostic were p...

where q(x) and r(x) are real valued and all have period a. Also q(x) is piecewise continuous, r ′′(x) is piecewise continuous in (0,b) and (b,a) where 0< b < a and r(x)≥ r0 (> 0). Those values of complex parameter λ, for which periodic or antiperiodic problem associated with (1.1) and the x-interval (0,a) has a nontrivial solution y(x,λ), are called eigenvalues. An equation giving the eigenvalu...

It was stated in previous papers (Avis, Bergel & Bray, 1955; Avis, Bergel, Bray, James & Shooter, 1956; Avis, Bergel & Bray, 1956) that the enzymie activity of purified xanthine oxidase from cow's milk, like that of other enzymes, deteriorates in aqueous solution under a variety ofmild conditions. Since then we recorded in a preliminary communication (Bergel & Bray, 1956) the stabilizing effect...

In this paper global linear independence, local linear independence and HH older continuity of the solution of the ve-coeecient reenement equation (x) = 4 X k=0 c k (3x ? k); ^ (0) = 1; are considered. Especially we construct HH older continuous solution of the above reene-ment equation which is globally linearly independent but locally linearly dependent. Also multiresolution and explicite con...

The reagent 1-ethyl-3-(3-[14C]trimethylaminopropyl)carbodiimide (ETC) was used to identify specific carboxyl groups on the cytochrome bc1 complex (ubiquinol-cytochrome c reductase, EC 1.10.2.2) involved in binding cytochrome c. Treatment of the cytochrome bc1 complex with 2 mM ETC led to inhibition of the electron transfer activity with cytochrome c. Sodium dodecyl sulfate-polyacrylamide gel el...
