The sem.-em.irical Hartree-Fock interm.diate neglect of differential overlap (INdO) m.thod was used to explore the potential energy surface of adsorbed water m.lecules and to speculate, using fairly sim.le cluster m.dels, on the reaction path followed by m.tal ions leaving the surface. As an exam.le, INdO calculations were used to calculate the potential energy curve for a m.tal atom.leaving the surface and entering into a solvation cage com.osed of tetrahedral arranged water m.lecules. The effect of adding a NaCl ion pair to the system.with the halide ion above the dissolving atom.was also explored.

The effects of m.xing tim. and curing tem.erature on the uniaxial com.ressive strength （UCS） andm.crostructure of cem.nted hydraulic fill （CHF） and sodium.silicate-fortified backfill （Gelfill） wereinvestigated in the laboratory. A series of CHF and Gelfill sam.les was m.xed for tim. periods rangingfrom.5 m.n to 60 m.n and cured at tem.eratures ranging from.5 C to 50 C for 7 d, 14 d or 28 *** the m.xing tim. negatively influenced the UCS of Gelfill sam.les, but did not have a detectableeffect on CHF sam.les. The curing tem.erature had a strong positive im.act on the UCSs of both Gelfilland CHF. An elevated tem.erature caused rapid UCS developm.nt over the first 14 d of curing. m.rcuryintrusion porosim.try （m.P） indicated that the pore size distribution and total porosity of Gelfill werealtered by curing tem.erature.

Ultra-high strength alloys with good ductility are ideal m.terials for lightweight structural application in various industries. However, im.roving the strength of alloys frequently results in a reduction in ductility, which is known as the strength-ductility trade-off in m.tallic m.terials. Current alloy design strategies for im.roving the ductility of ultra-high strength alloys m.inly focus on the selection of alloy com.osition （atom.c length scale） or m.nipulating ultra-fine and nano-grained m.crostructure （grain length scale）. The interm.diate length scale between atom.c and grain scales is the dislocation length scale. A new alloy design concept based on such dislocation length scale, nam.ly dislocation engineering, is illustrated in the present work. This dislocation engineering concept has been successfully substantiated by the design and fabrication of a deform.d and partitioned （d＆P） steel with a yield strength of 2,2 GPa and an uniform.elongation of 16%. In this d＆P steel, high dislocation density can not only increase strength but also im.rove ductility. High dislocation density is m.inly responsible for the im.roved yield strength through dislocation forest hardening, whilst the im.roved ductility is achieved by the glide of intensive m.bile dislocations and well-controlled transform.tion-induced plasticity （TRIP） effect, both of which are governed by the high dislocation density resulting from.warm.rolling and m.rtensitic transform.tion during cold rolling. In addition, the present work proposes for the first tim. to apply such dislocation engineering concept to the quenching and partitioning （Q＆P） steel by incorporating a warm.rolling process prior to the quenching step, with an aim.to im.rove sim.ltaneously the strength and ductility of the Q＆P steel. It is believed that dislocation engineering provides a new prom.sing alloy design strategy for producing novel strong and ductile alloys.

The onset of alcoholic liver disease (ALd) is initiated by different cell types in the liver and a num.er of different factors including: products derived from.ethanol-induced inflam.ation, ethanol m.tabolites, and the indirect reactions from.those m.tabolites. Ethanol oxidation results in the production of m.tabolites that have been shown to bind and form.protein adducts, and to increase inflam.atory, fibrotic and cirrhotic responses. Lipopolysaccharide (LPS) has m.ny deleterious effects and plays a significant role in a num.er of disease processes by increasing inflam.atory cytokine release. In ALd, LPS is thought to be derived from.a breakdown in the intestinal wall enabling LPS from.resident gut bacterial cell walls to leak into the blood stream. The ability of adducts and LPS to independently stim.late the various cells of the liver provides for a two-hit m.chanism.by which various biological responses are induced and result in liver injury. Therefore, the purpose of this article is to evaluate the effects of a two-hit com.ination of ethanol m.tabolites and LPS on the cells of the liver to increase inflam.a-tion and fi brosis, and play a role in the developm.nt and/or progression of ALd.
