Plasticized bone and soft tissue grafts and methods of making and using same
The present invention provides a plasticized dehydrated or freeze-dried bone and/or soft tissue product that does not require special conditions of storage, for example refrigeration or freezing, exhibits materials properties that approximate those properties present in normal hydrated tissue, is not brittle, does not necessitate rehydration prior to clinical implantation and is not a potential source for disease transmission. The invention replaces water in the molecular structure of the bone or soft tissue matrix with one or more plasticizers allowing for dehydration of the tissue, yet not resulting in an increase in brittleness of the plasticized product, and resulting in compressive and/or tensile properties similar to those of normal hydrated bone.

Semiconductor package and method and system for fabricating the same
A fabrication method of a semiconductor package includes: disposing a first wafer on a substrate having at least a conductive pad; stacking a second wafer on the first wafer, wherein the second wafer has a pre-open area corresponding in position to the conductive pad of the substrate; forming a protection layer on the second wafer; embrittling the protection layer on the pre-open area of the second wafer; and removing the embrittled portion of the protection layer and portions of the second and first wafers so as to form an opening to expose the conductive pad, thereby preventing an adhesive layer from being attached to a cutting tool as in the prior art.. .

Producing rigid polyurethane foams and rigid polyisocyanurate foams
Rigid polyurethane foams or rigid polyisocyanurate foams with low brittleness are produced by the reaction of polyisocyanate polyetherester polyols based on aromatic dicarboxylic acids obtained by esterification of a dicarboxylic acid composition containing aromatic dicarboxylic acids and aliphatic dicarboxylic acids, fatty acids, aliphatic or cycloaliphatic diols having 2 to 18 carbon atoms or alkoxylates thereof, and a polyether polyol having a functionality of not less than 2.. .

Method of patterning electrically-conductive film on flexible substrates
A method of patterning an electrically-conductive film is performed by providing a flexible substrate that carries the electrically-conductive film thereon to form a combined layer. The combined layer is then bent about a radius of curvature, so as to impart a stress on the brittle conductive film along the axis of curvature of the curved surface.

Profiled steel wire with high mechanical characteristics resistant to hydrogen embrittlement
This profiled wire, of nace grade, made of low-alloy carbon steel intended to be used in the offshore oil exploitation sector, is characterized in that it has the following chemical composition, expressed in percentages by weight of the total mass: 0.75<% c<0.95; 0.30<% mn<0.85; cr≦0.4%; v≦0.16%; si≦1.40% and preferably ≧0.15%; and optionally no more than 0.06% al, no more than 0.1% ni and no more than 0.1% cu, the balance being iron and the inevitable impurities arising from smelting the metal in the liquid state, and in that the steel is obtained, from hot-rolled rod stock cooled down to room temperature, and then having a diameter of about 5 to 30 mm, by subjecting this starting rod firstly to a thermomechanical treatment comprising two successive steps carried out in order, namely an isothermal quench, giving it a homogeneous perlitic microstructure, followed by a mechanical transformation operation carried out cold with an overall degree of work-hardening (or reduction ratio) of between 50 and 80% at most, so as to give the wire its definitive shape, and in that the profiled wire thus obtained is then subjected to a restoration heat treatment of short duration carried out below ac1 (preferably between 410 and 710° c.), giving it the desired final mechanical properties.. .

Method of determining reservoir properties and quality with multiple energy x-ray imaging
A method of evaluating a reservoir includes a multi-energy x-ray ct scan of a sample, obtaining bulk density and photoelectric effect index effect for the sample, estimation of at least mineral property using data obtained from at least one of a core gamma scan, a spectral gamma ray scan, an x-ray fluorescence (xrf) analysis, or an x-ray diffraction (xrd) analysis of the sample, and determination of at least one sample property by combining the bulk density, photoelectric effect index, and the at least one mineral property (e.g., total clay content). Reservoir properties, such as one or more of formation brittleness, porosity, organic material content, and permeability, can be determined by the method without need of detailed lab physical measurements or destruction of the sample.
