    Calculation of magnetic moments in Ho2C3 nanocrystals : The 6th joint magnetism and magnetic materials (MMM)-intermag conference (1994)

    Notizen: A general approach to the computation of effective magnetic moments in rare-earth carbides is described, and details of this calculation for Ho3+ ions in Ho2C3 are presented. This calculation is designed to explain the reduced magnetic moments, relative to free ion values, measured by dc SQUID magnetometry for Ho2C3 nanocrystals. Crystal-field splittings of the rare-earth ion in a particular symmetry site are determined by the operator equivalent method. Using the eigenvalues and eigenfunctions of the crystal-field Hamiltonian, the effective magnetic moment is then determined. For Ho3+ ions in Ho2C3, this method predicts a reduced magnetic moment, but the degree of reduction depends on the energy-level splittings and, therefore, the temperature. This magnetic moment is compared with previous experimental results, and the implications of the formal carbon charge, screening, and temperature are discussed.

    The influence of applied voltage on cutting forces in slow speed wood cutting (1980)
    Springer
    Wood science and technology 14 (1980), S. 63-68

    ISSN: 1432-5225

    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Maschinenbau
    Notizen: Summary Slow speed wood cutting tests were carried out in which cutting forces were measured as a function of applied tool-work electrical potential. The cutting tool and workpiece were electrically insulated so that there was no current flow. Applied potential had no discernible effect on the cutting forces measured in the cutting of unextracted and extracted wet wood.

    Experimental studies on band saw blade vibration (1981)
    Springer
    Wood science and technology 15 (1981), S. 145-159 
    Details
    ISSN: 1432-5225

    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Maschinenbau
    Notizen: Summary The band saw blade vibration under non-moving and moving conditions has been experimentally studied for band saw blades unfitted with saw tension and back crown, fitted only with saw tension, and only with back crown. The lateral natural frequency of a band saw blade was found to decrease by fitting saw tension in a saw blade, but there was little or no effect for blades having only back crown. The torsional natural frequency of a band saw blade increased by fitting saw tension in a saw blade, but again there was little or no effect of fitting back crown in a blade. The lateral natural frequency decreased by tilting the upper wheel for the band saw blades investigated. On the contrary, when the upper wheel was tilted the torsional natural frequency increased for an untensioned blade with no back crown, and blades fitted only with back crown, however, there was little or no effect for a band saw blade fitted only with tension. The lateral and torsional natural frequencies significantly affected the over all self-excited displacement vibration of band saw blades. However, the displacement vibration due to the frequency of the number of wheel rotation affected significantly the over all self-excited displacement vibration of a band saw blade fitted with excessive back crown.

    3H-ACh release from guinea pig gallbladder evoked by GABA through the bicuculline-sensitive GABA receptor (1984)

    Notizen: Summary We investigated the effect of GABA on the spontaneous efflux of 3H-acetylcholine (ACh) from the isolated guinea pig gallbladder loaded with 3H-choline. Application of GABA (10−5 M) caused a significant increase in the fractional rate of tritium efflux. This GABA-evoked efflux of ACh was inhibited by the perfusion of tetrodotoxin (10−6 M) and Ca-free medium. Nipecotic acid (10−4 M) did not affect the GABA-evoked release of ACh, indicating that ACh was not released by the entry of GABA into cholinergic nerve terminals. Bicuculline (10−6 M) and furosemide (10−6 M), the chloride ion channel blocker, inhibited the GABA-evoked ACh release. The application of muscimol (10−5 M), but not baclofen (10−5 M) also produced an increase in the fractional rate of ACh release. Thus, the GABA receptors involved in the increase of ACh release are bicuculline-sensitive. The GABA-evoked release of ACh was not altered by the perfusion with hexamethonium (10−5 M), thus indicating the presence of GABA receptors on the postganglionic cholinergic neurons. These findings suggest that bicuculline-sensitive GABA receptors probably coupled to a Cl− ionophore are present on postganglionic cholinergic neurons and are involved in the increase of ACh release in guinea pig gallbladder.

    The effects of wood-fiber directions on acoustic emission in routing (2000)
    Springer
    Wood science and technology 34 (2000), S. 237-252 
    Details
    ISSN: 0043-7719

    Thema: Land- und Forstwirtschaft, Gartenbau, Fischereiwirtschaft, Hauswirtschaft , Maschinenbau
    Notizen: Abstract The purpose of this study was to investigate the causes of changes in acoustic emission (AE) signals corresponding to changes in grain orientation in routing. Both the AE signals and the state of cutting process were recorded on high-speed video cameras in an attempt to clarify the relationships between them. Based on the results, it appeared that generated AE was closely related to the state of cutting, as well as the surface finish. The greater the AE, the more severe the cutting performance for inclination angles. The greatest AE was generated when machining failures – fuzzy grains – were produced. Concerning the annual ring angle, the AE count rate, lowest at 0 degrees, slightly increased until 75 degrees, and then rapidly reached its maximum at 90 degrees. Changes in the slope angle had also an effect on the AE signal. The AE count rate, highest at the 0 degrees, gradually decreased until 75–105 degrees, and then increased to reach its maximum at 180 degrees. Moreover, there were correlations between the AE count rate and surface roughness. Therefore, acoustic emission has shown promise for the monitoring of the surface roughness including various cutting conditions.
