Building efficient and flexible feature-based indices
(Elsevier, 1990)
If database management systems are to play an important role in CAD/CAM technologies, building engineering indices must be a primary task even though it is beyond conventional database practice. Information regarding design ...
Biaxial Yield for Nonlinearly Viscoelastic Materials with a Strain Clock
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-03)
A constitutive equation with a dilatation dependent reduced time is used to model the mechanical response of solid amorphous polymers such as polycarbonate. Such constitutive equations have the property that stress relaxation ...
Phosphate entry into erythrocytes at high levels
(Elsevier, 1962-05-21)
Human red blood cells reach an equilibrium of phosphate distribution at 37[deg] much faster with 0.11 M or intermediate levels than with 0.02 M and lower phosphate levels. Other divalent anions added to 0.02 M phosphate ...
Inhibierung des humanen B12‐verarbeitenden Enzyms CblC durch Antivitamine B12 – Kristallstruktur des inaktiven ternären Komplexes mit dem Kosubstrat Glutathion
(Wiley-VCH, 2017-06-19)
Antivitamine B12 gewinnen als robuste B12‐Dummys zunehmend biomedizinisches Interesse. Das potenzielle Antivitamin B12 2,4‐Difluorphenylethinylcobalamin (F2PhEtyCbl) wurde hergestellt, und seine 3D‐Struktur in Lösung und ...
Fabrication of in situ TiC reinforced aluminum matrix composites Part I: Microstructural characterization
(Kluwer Academic Publishers; Springer Science+Business Media, 1998-11)
In the present work traditional ingot metallurgy plus rapid solidification techniques were used to in situ produce Al-TiC composites with refined microstructures and enhanced dispersion hardening of the reinforcing phases. ...
Chemical Reagents for Investigating the Major Groove of DNA
(Wiley Periodicals, Inc.Oxford University Press, 2001-07)
Chemical modification provides an inexpensive and rapid method for characterizing the structure of DNA and its association with drugs and proteins. Numerous conformation‐specific probes are available, but most investigations ...
Statistical Emission Image Reconstruction for Randoms-Precorrected PET Scans Using Negative Sinogram Values
(IEEE, 2003-10-19)
Many conventional PET emission scans are corrected for accidental coincidence (AC) events, or randoms, by real-time subtraction of delayed-window coincidences, leaving only the randoms-precorrected data available for image ...
Topology Optimization of Thermally Actuated Compliant Mechanisms Considering Time-Transient Effect
(Elsevier, 2003-12-02)
Thermal transducers, which can be regarded as thermally actuated compliant mechanisms, have found a wide range of applications, due to easy accessibility of heat source, and due to their good controllability and reliability. ...
