    Mechanical Properties of Rough TiN Coating Deposited on Steel by Cathodic Arc Evaporation Technique (2005)
    Oxford, UK : Blackwell Science Inc
    Journal of the American Ceramic Society 88 (2005), S. 0 
    Details
    ISSN: 1551-2916
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Maschinenbau , Physik
    Notizen: We investigate here the axial and transverse mechanical properties of thin (1.5–7 μm) titanium nitride films deposited on high-speed steel by cathodic arc evaporation. The deposited films are rough, the roughness varying with film thickness. Mechanical properties deconvoluted from nanoindentation data show variations with penetration depth and scatter. We explore the effect of film surface roughness on these variations and comment on the possible effects of material heterogeneity and crystal structure on the estimated properties.

    Oxford, UK : Blackwell Publishing Ltd
    Geophysical prospecting 14 (1966), S. 0 
    Details
    ISSN: 1365-2478
    Quelle: Blackwell Publishing Journal Backfiles 1879-2005
    Thema: Geologie und Paläontologie , Physik
    Notizen: The paper describes a transistorised, portable proton precession magnetometer constructed for surface geophysical prospecting. Constructional and circuit details are furnished. The readout of the instrument is digital. The accuracy of measurement is ± 1 part in 20,000. The maximum gradient of the total field under which a satisfactory measurement can be made is about 1 gamma/cm. The sensing head uses a single coil system with distilled water as the proton sample.

    Ultrasound induced lubricity in microscopic contact (1997)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 71 (1997), S. 1177-1179 
    Details
    ISSN: 1077-3118

    Thema: Physik
    Notizen: A physical effect of ultrasound induced lubricity is reported. We studied the dynamic friction dependence on out-of-plane ultrasonic vibration of a sample using friction force microscopy and a scanning probe technique, the ultrasonic force microscope, which can probe the dynamics of the tip–sample elastic contact at a submicrosecond scale. The results show that friction vanishes when the tip–surface contact breaks for part of the out-of-plane vibration cycle. Moreover, the friction force reduces well before such a break, and this reduction does not depend on the normal load. This suggests the presence on the surface of a layer with viscoelastic behavior. © 1997 American Institute of Physics.

    Effect of roughness on the measurement of nanohardness—a computer simulation study (1997)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 71 (1997), S. 1059-1061 
    Details
    ISSN: 1077-3118
    Quelle: AIP Digital Archive
    Thema: Physik
    Notizen: This letter reports a simulation study of depth sensing nanoindentation on a rough surface. The estimated mean hardness and scatter are both influenced by roughness, irrespective of whether there is a genuine variation in mechanical property with deformation volume/depth. The scatter due to roughness always decreases with penetration depth. The roughness dependency of hardness is the product of two terms. The first term is independent of property variation with deformation volume/depth and arises due to the discrete nature of multiple contacts during indentation. The second term is due to property variation with deformation volume/depth, as changing roughness changes the aggregate strength of each contact island. © 1997 American Institute of Physics.

    A signaling and control architecture for mobility support in wireless ATM networks (1996)
    Springer
    Mobile networks and applications 1 (1996), S. 287-298 
    Details
    ISSN: 1572-8153
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Informatik
    Notizen: Abstract This paper presents a signaling and control architecture for mobility support in a “wireless ATM” network that provides integrated broadband services to mobile terminals. A system level protocol architecture for a wireless ATM network is outlined. The proposed protocol stack incorporates new wireless link MAC, DLC and wireless control sublayers, together with appropriate mobility extensions to the existing ATM network control layer. Wireless control and ATM signaling capabilities required for mobility support are discussed, and preliminary solutions are given for selected major functions. Potential extensions to standard Q.2931 ATM signaling are proposed to support handoff and service parameter/QoS renegotiation required for mobility. An associated wireless control protocol for supporting terminal migration, resource allocation, and handoff is discussed. Preliminary experimental results are given which validate the proposed handoff control protocol on an ATM network testbed.

    On forced torsional oscillation of a cylindrical shell of non-homogeneous material by the application of a periodic shearing force at one end (1969)
    Springer
    Pure and applied geophysics 73 (1969), S. 39-42 
    Details
    ISSN: 1420-9136
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Geologie und Paläontologie , Physik
    Notizen: Summary In the present note the author has considered the torsional vibration of a cylindrical shell of non-homogeneous material whose rigidity and density vary linearly with distance from the axis of the shell. It is assumed that one end of the shell is fixed while the other end is acted on by a periodic shearing force, both the inner and the outer curved surface being free from stress at all times.

    Exstrophy of the urorectal septum —report of two cases and embryological review (1992)
    Springer

    ISSN: 1437-9813
    Schlagwort(e): Exstrophy ; Urorectalseptum ; Unusualcongenital malformation

    Thema: Medizin
    Notizen: Abstract For the first time two cases of an unusual congenital malformation are described. Both patients had an isolated defect at the median raphe covered by colonic mucosa extending from a hypospadiac urethral orifice to the anal orifice. After a thorough review of the embryology, the authors designate this anomaly as exstrophy of the urorectal septum.

    Ideal technique and sites for intramuscular injection in infants and children (1989)
    Springer
    Pediatric surgery international 4 (1989), S. 140-142 
    Details
    ISSN: 1437-9813
    Schlagwort(e): Intramuscular injection ; Infants and children
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Medizin
    Notizen: Abstract Complications following intramuscular (IM) injections in infants and children are quite frequent. Various studies have revealed that in most of the cases drugs were either injected into the subcutaneous tissue plane or into the muscle, where a disparity between the volume of injected material and the volume of muscle mass where it was injected was obvious. The consequences were either fat-necrotic abscess or muscle fibrosis leading to deformity of the nearby joint. On the basis of our studies and other observations, the ideal technique of IM injection and the best sites for injection in infants and children are suggested in order to prevent complications.
