    Electrophoretic deposition and its use to synthesize ZrO2/Al2O3 micro-laminate ceramic/ceramic composites (1993)
    Springer
    Journal of materials science 28 (1993), S. 6274-6278 
    Details
    ISSN: 1573-4803

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Electrophoretic deposition has been employed to synthesize yttria-stabilized zirconia (YSZ)/alumina, laminar microcomposites with a total of 80 layers, 〉2mm. 10 wt% solids, ethanol suspensions of YSZ or Al2O3 powders were deposited layer by layer. The deposited samples had a green density, ~60% theoretical. The deposition process was characterized by the rate-of-deposition as a function of voltage and the microstructure of the sintered, theoretically dense samples was characterized by optical and electron microscopy. Microindentation was used to explore the mechanical properties of the laminates.

    Interaction of positronium with Co2+ and Cu2+ ions in aqueous solutions (1994)
    Springer
    Journal of radioanalytical and nuclear chemistry 181 (1994), S. 201-209 
    Details
    ISSN: 1588-2780

    Topics: Chemistry and Pharmacology , Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract Interactions of positronium in aqueous solutions of Co2+ and Cu2+ ions have been investigated at room temperature (297 K) at varying concentrations using both lifetime and Doppler broadening of annihilation radiation techniques. In the case of Co2+, the results indicate spin conversion reaction alone. However, in the case of Cu2+, oxidation is predominant with a small contribution of spin conversion reaction. The corresponding rate constants have been evaluated.

    Bacillus fermentation of soybeans (1993)
    Springer
    World journal of microbiology and biotechnology 9 (1993), S. 295-299 
    Details
    ISSN: 1573-0972
    Keywords: Bacillus ; Enterococcus ; fermentation ; kinema ; soybean
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Abstract Kinema fermentations of Indian and Canadian No. 1 soybeans by Bacillus sp. DK-W1 and by mixed cultures of Bacillus sp. DK-W1 and Enterococcus faecium DK-C1 were essentially identical. The viable cell count of Bacillus increased from an initial 105 to 1010 c.f.u./g wet wt after 48 h incubation at 37°C. The pH of the fermentation dropped from an initial 6.9 to about 6.4 after 8 h and then rose to 8.6 after 32 h, with a coincident increase in proteolytic activity and ammonia concentration. The fermentations containing E. faecium and Bacillus exhibited a greater initial pH decline and a slightly retarded subseqent increase in pH compared with fermentations with Bacillus only. The presence of E. faecium had no detectable effects on growth of the Bacillus, proteolytic activity, ammonia production or the final pH of the fermentations.

    Replacement of the urinary bladder with rectum (1994)
    Springer
    Pediatric surgery international 9 (1994), S. 567-570 
    Details
    ISSN: 1437-9813
    Keywords: Rectum ; Bladder substitute
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract The rectum can be used as a substitute for the urinary bladder such that the normal outlet for feces at the anus is left undisturbed and continent. Perfect and complete continence is achieved by creating a narrow neck of the rectal bladder with a sphincter around it and a narrow urinary outlet, a neourethra, also with a sphincter around it. Three different types of anomaly necessitating reconstruction of the urinary bladder were operated upon by this procedure. Three patients are doing well in respect to micturition and defacation, having achieved total continence for both.

    ISSN: 1437-9813
    Keywords: Duplication of bladder and urethra ; Dextrocardia with situs inversus

    Topics: Medicine
    Notes: Abstract A rare case of mirror-image dextrocardia with inverse visceroatrial relationship associated with a double symphysis pubis and splitting of the lumbosacral spine and duplication of the bladder and urethra is reported. The clinical findings and investigations are described. An embryological explanation is also suggested.
