    DETERMINING THE ACCURACY OF COHERENT OPTICAL IDENTIFICATION OF DIATOMS (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of the American Water Resources Association 15 (1979), S. 0 
    Details

    Notizen: : The discriminating capability of a coherent optical processor in identifying diatom species was tested using 25 species selected by diatom taxonomists. A 25 × 25 matrix of auto- and cross-correlations was used for this purpose. In no case did cross-correlation signals approach the intensity of auto-correlations indicating that false identifications were extremely improbable. Shape and height differences of the cross-correlation signals can be attributed to variations in diatom shapes, sizes, and cell wall morphology.

    Dynamic and static recordings of the comfortable zone (1978)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 5 (1978), S. 0 
    Details
    ISSN: 1365-2842
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: A dynamic and a static method of assessing the comfortable zone by means of a screw jack were compared in 12 subjects. Recorded under dynamic conditions the average width of the comfortable zone was approximately 3·0 mm, and under static conditions approximately 5·0 mm (P 〈 0·0001). It is suggested that in the dynamic experiments the larger output from receptors in the chewing system was responsible for the narrower zone, i.e. the more precise assessments of the comfortable zone.

    A new intra-oral screw jack (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 4 (1977), S. 0 
    Details

    Thema: Medizin
    Notizen: A new pattern of screwjack for assessing the vertical dimension for occulusion utilizing an edentulous patient's proprioceptive sensation is described. It provides a greater range of movement than other, giving infinitely variable heights between 9 and 21 mm. The elements being captive, it cannot come to pieces in use.Laboratory experiments were contrived to define the magnitude of reading errors and the play in the screw threads. It was found that, only in instances where a graduation related closely to the datum mark, did errors of interpretation arise. These were found to exceed the height set for test purposes by 0·1 mm consistently. An error of this order is of no practical significance clinically and is no impediment to such an application of the device. Mean play in the new pattern jacks was 0·01 mm compared to 0·05 mm in the Timmer versions.In a clinical experiment the performance of the screw was compared to that of Timmer. Statistical evidence was found which suggested a functional difference between the two, the new pattern being significantly more accurate.

    Short-term changes in the perception of comfortable nandibular occlusal positions (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 4 (1977), S. 0 
    Details

    Thema: Medizin
    Notizen: In search of a new clinical method for determining the occlusal height of full dentures, the perception of the comfortable zone was studied in fifteen edentulous patients. In each experimental session perceptual changes were recorded from forty-four consecutive applications of a screw jack per subject. Two stages in perceptual acuity were found. An initial stage, in which only minor variations occurred among the final screw adjustments which the subjects made when they assessed the borders of the comfortable zone. In the ensuing stage greater variations emerged, indicating a deterioration in the ability of the subjects to disciminate.

    A comparative study of three different approaches to the comfortable zone (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 4 (1977), S. 0 
    Details
    ISSN: 1365-2842
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: By means of a screw jack device, applied to thirteen edentulous subjects, the comfortable zone was approached in three different ways, by the central, the internal and the external approaches. Correspondingly, the zonal borders behaved differently. Applying the central approach it was found that the initial height of the screw jack had a lingering effect upon subsequent adjustments of the screw. Moreover, lower border data collected by the external approach distinguished themselves form other zonal border data by showing a signifincantly lower susceptibility to successive adjustments. The study suggests that muscle activity is a factor on which the perceptual mechanism relies, when a zonal border is assessed subjectively by a patient.

    The delay time of tooth vibration signal recorded at facial skin surface (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 7 (1980), S. 0 
    Details
    ISSN: 1365-2842
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: The onset of a tooth vibration signal with a mini acceleration pickup attached to the skin on the forehead was delayed by 0.1788 ms on average after the actual tooth impact. When the signal was recorded at the zygomatic arch, the delay time was 0.1008 ms on average, which was significantly shorter than that obtained from the forehead (P 〈 0.001). The difference due to a transposition of the vibrated tooth was also smaller (0.025 〈 P 〈 0.05) and had almost no effect on the intensities of the tooth flipping force. The delay time was even more prolonged when a poor frequency specification pickup and/or low pass filter were applied.

    Condylar displacements related to dynamic and static recordings of the comfortable zone (1979)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of oral rehabilitation 6 (1979), S. 0 
    Details
    ISSN: 1365-2842
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Medizin
    Notizen: In a previous study it was found that the distance between the borders of the comfortable zone was considerably wider when the zone was recorded statically rather than dynamically. However, it was not reported how condylar displacements may be related to the zonal borders. Therefore, an attempt is made in the present study to translate zonal border recordings into the equivalent amount of condylar rotation. Using a dental articulator, it was found that the condyles rotated 4.96°, when the comfortable zone was recorded statically, and 2.50°, when the zone was recorded dynamically. The difference, 2.46°, was statistically significant (P 〈 0.001).

    Determination of pH in reversed micelles (1982)
    Springer
    Colloid & polymer science 260 (1982), S. 697-701 
    Details
    ISSN: 1435-1536
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Chemie und Pharmazie , Maschinenbau
    Notizen: Abstract The pH in the reversed micellar system of di(ethylhexyl) sodium sulfosuccinate (Aerosol OT, AOT) / phosphate buffer solutions/octane was determined by a P-NMR technique, and pHs in the reversed micelles containing buffer solutions other than the phosphate buffer solution were measured by the spectrophotometric method with the aid of Phenol Red. pHs in reversed micelles were found to be substantially determined by the buffer capacity of buffer solutions solubilized into the systems. By means of both the methods, pKa of Phenol Red in the systems was found to be 7.7, which is almost consistent with that in water. Analysis of Na-NMR spectra indicates that the mobility of the sodium ion of AOT is independent of the molar ratio of water to AOT when the ratio is above 7 and is restricted strongly by the interaction with the sulfonate group of AOT. The relationship between pH and the mobility of the sodium ion was discussed on the basis of the data of Na-NMR spectra.
