    Sensitive Catalase Test for End-point Temperature of Heated Chicken Meat (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 59 (1994), S. 0

    Notes: Our improved method enables detection of catalase-related activities as a biochemical marker for estimating cooking end-point temperature (EPT). The broad range of inactivation temperature in chicken tissues was first determined to be 〉 68°C and 〈C 72°C. Then samples were heated to EPTs from 69 to 71.5°C at 0.5°C intervals. The catalase activity at 23 and 37°C was followed up to 120 min. The probability of obtaining a positive result with an EPT of 69°C was 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:00221147:JFDS494:ges" location="ges.gif"/〉0.99 after 45 min when incubated at 23°C. This probability decreased to 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:00221147:JFDS494:ges" location="ges.gif"/〉0.03 as EPT increased to 71°C. Higher incubation temperatures (37°C) increased the probability of positive results.

    Dynamic domain instability and popcorn noise in thin-film heads : 38th Annual Conference on Magnetism and Magnetic Materials (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 75 (1994), S. 6391-6393 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: The effects of dynamic domain instability on popcorn noise probabilities were studied by correlating the measured popcorn noise probabilities with the instantaneous observations of dynamic domain states of thin-film heads during and after writing. Heads with large peak popcorn noise probabilities at intermediate values of write current amplitude were observed to exhibit asymmetric domain patterns and occasional popping wall motion in the yoke structure during writing. The occurrences of dynamic domain instability were imaged by comparing many instantaneous domain patterns at 10 μs after a specific write current excitation. Delayed-relaxation Barkhausen wall jumps near the backgap closure were observed occasionally in several noisy heads. Quantitative correlation between the probabilities of popcorn noise and dynamic domain instability was also obtained in a very noisy head. Dynamic domain instabilities in the yoke are thus responsible for the peak popcorn noise probabilities in thin-film heads.

    Dynamic response of domain walls on the air-bearing surface of thin-film heads : 38th Annual Conference on Magnetism and Magnetic Materials (1994)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 75 (1994), S. 6394-6396 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The domain configurations on the air-bearing surface (ABS) of inductive thin-film recording heads were studied. It was found that, instead of being a single domain structure, the ABS of a thin-film head usually has multidomains. The direction of the domain walls is neither parallel nor perpendicular to the gap plane. The magnetization was found to be in the plane of the ABS along the track width, with the magnetizations on the two sides of the domain walls either "head-to-head'' or "tail-to-tail.'' The domain walls are slanted in order to spread the magnetic charges along the wall over a larger region, thereby reducing magnetostatic energy in this configuration. The responses of the domain walls are not all in phase, and they are generally out of phase with the rotational process along the gap edge. The magnetization configuration on the ABS and in the throat and the sloped region were investigated in one head and correlated with the domain walls on the ABS.

    Domain structures and dynamics near the backgap closure of thin-film heads : 35th annual conference on magnetism and magnetic materials (1991)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 69 (1991), S. 5414-5416 
    Details
    ISSN: 1089-7550

    Topics: Physics
    Notes: Statically unstable spikelike reversed magnetic domains emanating from the backgap closure of thin-film heads have been observed with high-frequency (1–20 MHz) and high-current amplitude (20–80 mA p-p) drive fields by using a wide-field magneto-optic domain observation system with a 10-nsec exposure time. The spikelike domains are repeatedly nucleated and annihilated within the drive cycle and do not remain after removal of the excitation. The formation of spikelike domains is due to the magnetization rotation back to the nearest easy directions after fanning out near the backgap closure to carry the spreading flux out of (or converging flux into) the backgap closure. The spikelike domains block the flux flow into and out of the backgap closure at excitation frequencies above 10 MHz due to the slow domain annihilation process. It is speculated that occasional failure of these spikelike domains to annihilate after a write pulse could lead to noise when they suddenly collapse during read out.

    Mevva ion source for the application of material surface modification : Proceedings of 5th international conference on ion sources (1994)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 65 (1994), S. 1295-1297 
    Details

    Source: AIP Digital Archive
    Topics: Physics , Electrical Engineering, Measurement and Control Technology
    Notes: Several versions of Mevva ion sources have been developed in our institute since 1988. It operates in a pulsed mode with a pulse length of 1.2 ms and a repetition rate of up to 50 pps. A time-averaged beam current of 10 or 50 mA has been extracted at 30–80 kV from Mevva IIA-H and Mevva IIB, respectively. In order to develop surface modification of materials by ion implantation we have constructed three kinds of Mevva ion source implantation systems. High dose (3–5×1017 cm−2) implantation with Ti, Ce, Y, and Ti+C, etc. has been carried out for improving the lifetime of metal cutting tools, relay contacts, dies, and some sophisticated components.

    Relaxation processes in hyperbranched polyesters (1994)

    Polymer bulletin 32 (1994), S. 679-685

    Notes: Summary Dielectric permittivity and loss have been measured over the frequency range 10-2 Hz-10 kHz between 100 K and 350 K for samples of 50/50 mixtures of each of two hyperbranched polyesters, one five-generation hydroxy functional (5G-OH) and one threegeneration alkyl-terminated polymer (3G), with dielectrically inactive linear polyethylene. The thermal transitions of the hyperbranched polymers were studied with differential scanning calorimetry. Three relaxation transitions were found in 5G-OH: α, the glass-rubber transition and two subglass processes denoted β and γ showing Arrhenius temperature dependence both with an activation energy of 96±2kJ mol-1. The low temperature process could be assigned to motions of the terminal hydroxyl groups whereas β is due to reorientation of the ester groups. Sample 3G showed only a glass transition and one subglass process being assigned to reorientation of the ester groups. The high activation energy (202 kJ mol-1) of this process indicates that the ester groups are highly constrained in this polymer.

    Topics: Biology , Medicine
    Notes: Abstract The hypothesis that biophotons display a high degree of coherence was tested by measuring photocount statistics (PCS) of the ultraweak photon emission from three living organisms (cucumber seedling, mungbean seedling and soybean rhizobium bacteroids) with a high-sensitivity single-photon counter. For comparison, the same experiments were performed for laser beam, randomized laser beam, chemiluminescence from autoxidation of luminol and the dark counts of the equipment. Photocount distributions, close to Poissonian, were observed for the three tested biological systems but not for the pure chemiluminescence of luminol.
