Our previous work has shown that both induction, after addition of inducer, and loss of ability to produce allophanate hydrolase, after removal of inducer, proceed more rapidly than expected from the reported half-life of messenger ribonucleic acid in Saccharomyces cerevisiae. As a basis of rectifying these observations, we have characterized induction and repression of allophanate hydrolase sy...

We describe a sequence of reciprocal interactions between cloned inducer T cells and antigen-presenting cells (APC) that results in selective depletion of the antigen-reactive inducer cells. We show that corecognition of antigen and I-A by hapten-reactive inducer T cell clones results in (a) release of macrophage-activating factor (MAF) and other lymphokines, (b) expression of lytic activity by...

This document deals with the design of a Permanent Magnet Synchronous Motor (PMSM) to peripherally drive counter-rotating pump inducer. The motor/pump is associated using rim-driven principle where motor’s active parts are located at periphery inducer blades. It proposes Halbach array permanent magnets for rotor motor. solution allows generation Sinusoidal Electromotive Force (EMF). Therefore, ...

The inducer specificity and kinetics of induction of the ara operon were examined in Escherichia coli B/r. A difference in the kinetics of induction was found between our B/r strains and the K-12 strain previously described by Schleif. The roles of active transport and metabolism of inducer, and of cell density, in induction were studied. d-Fucose and beta-methyl-l-arabinoside were competitive ...

We measured contrast detection thresholds for a small (3.6 x 3.6 arc min) square target in the presence and absence of spatially identical pedestal stimuli, and of a spatially non-overlapping inducing line (3.6 x 23 arc min). Results for the pedestal stimuli replicated the classical "dipper function", thresholds being reduced by near-threshold pedestals and increased at higher pedestal contrast...

The inducer is often used to prevent cavitation in a centrifugal pump. However, it may lead deterioration of the performance pump when poorly matched with impeller. Numerical simulations are employed study effects matching, specifically, axial space and circumferential deflection between impeller, on performance. results show that destroys rotational symmetry velocity distribution at inlet resu...

Given that biochemical circuits can process information by using analog computation, a question is: What compute? This paper considers the problem of to distinguish persistent signals from transient ones. We define statistical detection over reaction pathway consisting three species: an inducer, transcription factor (TF) and gene promoter, where inducer activate TF active bind promoter. model c...

Chiral lanthanide complexes can be prepared by choosing the achiral antenna ligand and chiral inducer independently. With this modular approach, optimized for use in efficient CP-OLEDs may obtained.
