A considerable amount of Hg is retained in flue gas desulfurization (FGD) gypsum from Wet Flue Gas Desulfurization (WFGD) systems. For this reason, it is important to determine the species of Hg in FGD gypsum not only to understand the mechanism of Hg removal by WFGD systems but also to determine the final fate of Hg when FGD gypsum is disposed. In this study, Temperature Programmed Decompositi...

Temperature-programmed desorption (TPD) results after chemisorption of carbon monoxide (CO) and carbon dioxide (CO,) on polycrystalline graphite are presented. CO adsorbs onto graphite with a very low sticking coefficient. After CO Chemisorption, CO (mass 28 amu) desorbs in two temperature regions, between 400 and 700 K and between 1000 and 1300 K, and COz (mass 44 amu) desorbs below 950 K. The...

AIMS To develop and assess a cytochemical technique for the light microscopical detection of oxidase activity in pathogenic bacteria. METHODS Live bacterial cells were deposited on to aminopropylsilane treated glass coverslips by centrifugation, dried, then reacted with either 1% (w:v) n,n,n',n'-tetramethyl-p-phenylene diamine (TPD) or 5 mM diaminobenzidine (DAB) at 37 degrees C. The preparat...

BACKGROUND The 2014 European Union (EU) Tobacco Products Directive (TPD) was negotiated in a changed policy context, following adoption of the EU's 'Smart Regulation' agenda, which transnational tobacco companies (TTCs) anticipated would increase their influence on health policy, and the WHO Framework Convention on Tobacco Control (FCTC), which sought to reduce it. This study aims to explore th...

The purpose of this paper is to provide insight into how rural teachers were empowered to become co-creators of innovative practices in their classrooms. The co-creation was operationalised as a merging of teachers existing knowledge of their subject, context and new knowledge of using mobile tablets towards enhancing their teaching practices in the Eastern Cape Province of South Africa over a ...

reduced dark current enabled a constant responsivity from light intensity of 10 −2 Wcm −2 all the way down to 12 pWcm −2 , resulting in a very large linear dynamic range of 90 dB. [ 5 ] However, the insertion of 25 nm C-TPD between PEDOT:PSS and C 60 interface also blocked the tunneling of electrons (secondary electron injection) into C 60 even under large reverse bias of –6 V, and thus annulle...

BACKGROUND Voluntary lumbopelvic control is compromised in patients with back pain. Loss of proprioceptive acuity is one contributor to decreased control. Several reasons for decreased proprioceptive acuity have been proposed, but the integrity of cortical body maps has been overlooked. We investigated whether tactile acuity, a clear clinical signature of primary sensory cortex organisation, re...

This paper describes the Visible Human (VH) part of the Trans-Pacific Demonstrations of the G7 Information Society-Global Interoperability for Broadband Network (GIBN) Projects. Aiming at a world-wide Visible Human Anatomical Co-laboratory, an application (VHP Viewer) was developed, which was used for data transmission testing (Trans-Pacific Demonstration of Visible Human) through broadband sat...
