The dependence of the permittivity, on uniaxial pressure of ceramics in the paraelectric, ferroelectric and relaxer phases has been investigated for BaTiO3, Pb(ZrTi)O-3 and Pb(Mg1/3Nb2/3)O-3. In the paraelectric ic phase, upon the application of stress, a ...
DSA type electrodes (IrOx/Ti) were prepd. by induction heating technique which allows a rapid decompn. of the precursor under anaerobic conditions. With this type of electrode, an activation process is obsd. in cyclic voltammetry which can be related to th ...
We studied the possible involvement of corticosteroids in the establishment and long-term expression of contextual fear conditioning and questioned whether a corticosteroid action might be dependent upon stimulus intensity at training. Experiments included ...
Putative intersubunit electrostatic interactions between charged amino acids on the surfaces of the dimer interfaces of leucine zippers (g-e' ion pairs) have been implicated as determinants of dimerization specificity. To evaluate the importance of these i ...
We illustrate the propagation of light in a new type of coupling mask for lensless optical lithography. Our investigation shows how the different elements comprising such masks contribute to the definition of an optical path that allows the exposure of fea ...
An algorithm for connection admission control (CAC) in the case where connections are of the variable bit rate (VBR) type and the trunk carrying the multiplexed VBR connections is itself a VBR connection. ...
The light-induced degrdn. of Tinopal DMS-X, a stilbene type fluorescence whitening agent (FWA) which is quite resistant to biodegrdn., is described. This substance has been chosen for the study of the titania-induced degrdn. of polycyclic stilbenes since i ...
In Al0.3Ga0.7As/GaAs quantum wells bordered by ultrathin (one or two monolayers) AlAs layers, the AlAs layer has been shown to provide a well for electrons at high pressure [Phys. Rev. B 45, 11 846 (1992)]. In this work, the same type of structures but gro ...
A classification of models for animating synthetic actors is proposed. The classification depends on the motion control method used (geometric, physical, or behavioral) and the type of actor interaction (single actor, actor-actor, actor-environment, and an ...
Mutations of the glycoprotein rBAT cause cystinuria type I, an autosomal recessive failure of dibasic amino acid transport (b(0,+) type) across luminal membranes of intestine and kidney cells. Here we identify the permease-like protein b(0,+)AT as the cata ...
