Surface-crosslinked superabsorbent polymer (SAP) particles having a clay in the vicinity of the surfaces of the SAP particles a clay are disclosed. The clay is added to SAP particles during surface crosslinking to substantially reduce the generation, and recycling, of SAP fines, and to provide SAP particles having an improved acquisition rate of fluids and an improved permeability of a fluid through the swollen SAP particles. Diaper cores and absorbent articles containing the surface crosslinked SAP particles also are disclosed.

摘要:
A method implemented in the form of a computer simulation code for evaluating the free energy of binding between polypeptide amino acid residues and one or more molecular fragment types is presented. The basis of the method is a novel weighted Metropolis Monte Carlo approach for sampling the grand canonical ensemble. By making use of the properties of the grand canonical ensemble, the affinity of fragments for binding in the vicinity of each protein residue can be efficiently computed. The binding volume associated to each fragment-residue pair is estimated on the basis of a simple proximity criteria, and a useful affinity mapping of the protein surface can be obtained in this way. The analysis of such data for various fragment types provides valuable information to help identify protein binding sites, as well as to identify key fragments used for building potential drug leads.

摘要:
Methods and systems for determining the affinity between polypeptide amino acid residues and one or more molecular fragments, and for using the affinity values to aid in drug design including a computer simulation which calculates the interaction energy between a polypeptide and at least one molecular fragment. An affinity value is then assigned to at least one fragment and residue pair if the fragment is in the vicinity of the residue. Affinity values are used to rank fragments, build ligands and determine binding sites.

A display as for images and/or information comprises a plurality of light-emitting fibers disposed in side-by-side arrangement to define a viewing surface. Each light-emitting fiber includes a plurality of light-emitting elements disposed along its length, each having two electrodes between which are applied electrical signals to cause the light-emitting element to emit light to display a pixel or sub-pixel of the image and/or information. The light-emitting fiber includes an electrical conductor disposed along its length to serve as a first electrode, a layer of light-emissive material disposed thereon, and a plurality of electrical contacts disposed on the light-emissive material to serve as the second electrodes of the light-emitting elements, and are formed in a continuous process wherein a transparent fiber passes through a plurality of processing chambers for receiving the electrical conductor, the light-emissive layer and the plurality of electrical contacts thereon. The method of making a light-emitting fiber comprises providing a length of a fiber, forming a first electrode along the fiber, depositing a light-emitting material along the fiber in electrical contact with the first electrode, and forming a plurality of second electrodes along the fiber in electrical contact with the light-emitting material.
