    Effect of Woven Fabric Biodegradable Polyglycolic Acid on Joint Resurfacing with Fresh Chondrocytes in a Rabbit Model (2007)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: To evaluate the effectiveness of the cell-material in situ on joint resurfacing, a wovenfabric polyglycolic acid (PGA) treated with fresh chondrocytes was used for repairing cartilagedefects. Full-thickness defects were created in the weight-bearing surfaces of the femoralintercondylar fossa in a rabbit model. The defect was filled with and without PGA under surgicalcondition. Before implantation, chondrocytes were co-cultured with PGA for one day. The animalswere sacrificed at eight weeks after implantation and evaluated grossly and histological score.Morphological examination showed that for PGA/chondrocytes group, the repaired tissue appearedsimilar in color and texture to the surrounding articular surface. While for the untreated control, nocartilage-like tissue was observed at all defects, but connective fibrous tissue. Histological analysisrevealed neochondrogenesis and clusters of cartilage matrix with specific safranin-O staining for thePGA/cell group. The Gross and histological evaluation indicated a significantly higher score forPGA/cell group than for PGA and control group. These results suggest that the woven fabric PGAmay facilitate the formation of cartilage tissues by providing a biodegradable and good-handlevehicle for the delivery to and retention of organized cell matrix constructs in vivo site. It mighttherefore enhance neochondrogenesis because of the superior biodegradable and biocompatible ofPGA scaffold sheet, while the more suitable biological environment might sustain cell growth andin situ cell function, suggesting a promising candidate for functional tissue engineering of clinicalenvironment

    Simulation of magnetoresistive response in a small Permalloy strip : 37th Annual conference on magnetism and magnetic materials (1993)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 73 (1993), S. 6504-6506

    Notes: A micromagnetic simulation program has been used to calculate the magnetoresistance of a free-standing 4 μm×1 μm×200 A(ring) Permalloy strip for a variety of numerical hysteresis loops in which a constant bias field is applied along the easy axis and a variable field is applied along the hard, in-plane axis. The main purpose of this study is to correlate noise in the magnetoresistive response with micromagnetic behavior and to show that the noise is considerably reduced by the application of the bias field. Two different methods for evaluating the magnetoresistive response are discussed.

    Dynamical micromagnetics of a ferromagnetic particle: Numerical studies : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: We have developed a general purpose dynamical micromagnetic code to solve the damped Gilbert equation using the finite element method. We report a study of magnetization switching in a ferromagnetic prolate ellipsoid with aspect ratio of 4.6:1. Switching starts with curling at the middle of the particle, then continues with more complex magnetization configurations, heavily influenced by the damping constant. In general, lighter damping produces more sharply defined domain walls. The critical field for switching has a mild dependence on the damping constant. © 1996 American Institute of Physics.

    Notes: NURBS surface representation, combined with Differential Evolution (DE), enables us toperform automated non-imaging reflector design. The overall result is a simple automated nonimagingreflector design technique and only a little data such as desired illuminance distribution andsearching limits are needed. Merit functions specific to non-imaging reflector design are presented.Using different merit functions, the generated illuminance distribution can be uniform as well asconcentrated. DE is performed to obtain the reflector that generates the desired illuminancedistribution. The photometric distributions are calculated through Monte-Carlo ray tracing and theilluminance value is used to calculate the merit function value. The validity of the proposedapproach is demonstrated by optimization examples. Almost the same uniform illuminancedistribution can be obtained using the algorithm proposed in this paper as that obtained by edge-raymethod.A concentrated illuminance distribution can also be generated using the algorithmproposed

    Notes: Summary Four three-armed poly(glycidyl ether)s with biphenyl mesogenic group and various lengths of spacer, new side-chain liquid crystalline polymers, were synthesized by cationic ring-opening polymerization of the corresponding monomers in the presence of 2,2-dihydroxymethylbutanol and BF3·OEt2 as initiator. The structures of the obtained poly(glycidyl ether)s were verified by 1H and 13C NMR spectroscopy, and their liquid crystalline behaviors were studied by differential. scanning calorimetry (DSC and optical polarizing microscopy (OPM).

    On Some Polyhedra Covering Problems (2000)
    Springer
    Journal of combinatorial optimization 4 (2000), S. 437-447 
    Details
    ISSN: 1573-2886
    Keywords: computational geometry ; polyhedra covering ; NP-hard
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mathematics
    Notes: Abstract Let P 0, P 1 be two simple polyhedra and let P 2 be a convex polyhedron in E 3. Polyhedron P 0 is said to be covered by polyhedra P 1 and P 2 if every point of P 0 is a point of P 1 ∪ P 2. The following polyhedron covering problem is studied: given the positions of P 0, P 1, and P 2 in the xy-coordinate system, determine whether or not P 0 can be covered by P 1 ∪ P 2 via translation and rotation of P 1 and P 2; furthermore, find the exact covering positions of these polyhedra if such a cover exists. It is shown in this paper that if only translation is allowed, then the covering problem of P 0, P 1 and P 2 can be solved in O(m 2 n 2(m + n)l)) polynomial time, where m, n, and l are the sizes of P 0, P 1, and P 2, respectively. The method can be easily extended to the problem in E d for any fixed d 〉 3.

    Notes: The synthesis of 1-propenyl ether-functionalized siloxanes (PFS) has been achieved by the controlled, rhodium-catalyzed, chemoselective hydrosilation of 1-allyloxy-4(1-propen-oxy) butane with various H-functional siloxanes. It was shown that the hydrosilation pro-ceeds exclusively at the allyl ether group of 1-allyloxy-4(1-propenoxy) butane without par-ticipation at the 1-propenyl ether group. The photoinduced cationic polymerization of these monomers was studied using various analytical techniques and found to take place very rapidly. © 1995 John Wiley & Sons, Inc.

    Topics: Chemistry and Pharmacology
    Notes: The monoterpene diepoxides isoascaridole (III), γ-terpinene diepoxide (V), and limonene diepoxide (VIII) were prepared from the corresponding hydrocarbons and their reactivity in photoinitiated cationic polymerization examined. Both V and VIII underwent facile and rapid polymerization to give crosslinked polyethers III, but although highly reactive, did not undergo crosslinking polymerization. With the aid of model compounds it was determined that the rearrangement of one of the epoxy groups of III takes place in the presence of photogenerated acid to give an epoxy ketone (XIII) as the primary product. XIII undergoes very sluggish polymerization. © 1995 John Wiley & Sons, Inc.
