This article focuses on Barbara Bray, an English woman of letters who worked for several decades with the BBC as a translator and adaptor plays novels radio, but also critic scriptwriter. Evidence found at Written Archives Centre reveals that Bray was very vocal about her rights multitasking cultural agent: when she didn’t fight better fees, demanded variety skills involved in work intercultura...

Land degradation and the associated soil acidity are critical challenge for crop production in Ethiopian highlands. Since liming is expensive, farmers have developed an alternative agroforestry system by integrating Acacia decurrens into their landscapes. The expansion rate of this was assessed over last three decades. effects charcoal-making kiln sites on properties were investigated five year...

The point of zero charge (PZC) is an inherent electrokinetic property biochars (BC). It influences the adsorption process under certain pH conditions. Herein, we report method determination PZC values ten standard BCs. We used salt addition to select BCs with suitable properties for methylene blue (MB) removal from aqueous solutions. were obtained by pyrolyzing five different biomasses at two d...

The previous papers of this series (Bray, Thorpe & White, 1951, 1952e; Bray, Humphris, Thorpe, White & Wood, 1952b, c, d) reported a study of the kinetics in vivo of some reactions involving benzoic acid and some of its precursors, certain precursors of phenols and a series of substituted phenols. A mathematical model was worked out which could account for the effect upon metabolic fate of dose...

in this study, cross linked chitosan resin (ccr) was prepared by cross linking chitosan with glutaraldehyde, and then î±-ketoglutaric acid-modified chitosan resin (kcr) was obtained by modifying ccr with î±-ketoglutaric acid. the sorption behavior of methylene blue (mb) on kcr and ccr from aqueous solution was investigated. the effect of various experimental parameters (e.g. initial ph, sorbent...

We address the problem of evaluation multiloop Feynman integrals by means their Mellin-Barnes representation. After a brief overview available capabilities through open source toolkits and application in various circumstances, we introduce new code MBcreate which allows one to automatically deduce concise representation for given parametric integral. A thorough discussion its implementation use...
