Long term bending behavior of ultra-high performance concrete (UHPC) [PDF]
Constructii: Journal of Civil Engineering Research, 2014 Unlike normal concrete (NC) the behavior of ultra-high performance concrete (UHPC) is different under long-term efforts, if we refer to creep, shrinkage or long-term deflections.

Advanced Engineering Materials, EarlyView.The present work reports the microstructural, mechanical, and texture evolution of a dissimilar combination laser‐welded maraging steel with 4340 steel. This is important for aerospace applications. The demand for dissimilar welding is growing rapidly with the requirement of efficient and durable joints.

DEFLECTED PRESENTATION IN LABOR. [PDF]
JAMA: The Journal of the American Medical Association, 1902 The obstetrical terminology lacks in general exactness and precision. This is especially true, so far as slightly deflected head presentations are concerned. Not only in occasional papers and in general practice, but in textbooks which are considered standard books the normal head presentation is spoken of as vertex presentation, while there is no ...

Advanced Engineering Materials, EarlyView.The influence of Fe particle size on in situ alloying of Fe–SiC powder blends in PBF‐LB/M is revealed. Contrary to expectations, the coarser Fe fraction provides a broader crack‐free processing window and slightly improved elemental homogeneity while producing higher but more variable hardness. The results highlight a complex trade‐off between particle

Interception and deviation of near earth objects via solar collector strategy [PDF]
, 2008 A solution to the asteroid deviation problem via a low-thrust strategy is proposed. This formulation makes use of the proximal motion equations and a semi-analytical solution of the Gauss planetary equations.

Advanced Functional Materials, EarlyView.Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.
