Single-phase induction machines are found in various appliances such as refrigerators, washing machines, driers, air conditioners, and fans. Large concentrations of single-phase induction motor loads such as air conditioners and other motorcompressor loads can adversely impact the dynamic performance of a power system. An understanding of the dynamics of this type of induction machine is needed...
EKSTEEN, P. A . L. & HUISMAN S, H. Interferon induction by bluetongue virus and bluetongue virus ribonucleic acid. Onderstep oort]. vet . R es. 39(3), 125-132 (1972). The stimulation of interferon synthesis by bluetongue virus and by bluetongue virus ribonucleic acid was investigated in order to determine if there is a difference in the mechanism of induction. The molecular mass of the interfer...
Main flux saturation in induction machines plays an important role in a number of operating regimes and therefore has to be accounted for in the process of modelling. The current state space model of a saturated induction machine has gained substantial popularity recently as an excellent tool for transient and steady-state time domain analysis of induction motor drives when the main flux satura...
The bisphosphine-catalyzed double-Michael addition of dinucleophiles to electron-deficient acetylenes is an efficient process for the synthesis of many nitrogen-containing heterocycles. Because the resulting heterocycles contain at least one stereogenic center, this double-Michael reaction would be even more useful if an asymmetric variant of the reaction were to be developed. Aminophosphines c...
Chronic lymphocytic leukemia (CLL) remains an incurable disease that requires innovative new approaches to improve therapeutic outcome. Many Ferula species, including F. asa-foetida, synthesize terpenyloxy coumarins. One of these coumarins is umbelliprenin, which has been implicated with induction of apoptosis in some cancer cell lines. In this study induction of apoptosis by umbellipre...
pretreatment of adults of iraq strain of afhstephenst with a sub-letlial dose of pcrmethrin resulted in a 65% enliancemenl of tolerance to this insecticide. similarly, pre-exposure of dub-lpr larvae to a sub-lethal dose of pcrmethrin resulted in increased tolerance to pcrmethrin. for the sensitive ind-s strain, the inductive effect was smaller. tiie results of bioassays of resistant and suscept...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
It has been shown recently that double-stranded ribonucleic acid (RNA) from different sources stimulates the release of interferon into the circulatory system when injected intravenously into rabbits. The same RNA preparations protected mice from viral infections and prevented the viral cytopathic effect in cultures of rabbit kidney cells (A. K. Field et al., Proc. Natl. Acad. Sci. U.S. 58:2102...
Apoptosis mediated by Fas ligand (FasL) interaction with Fas receptor plays a pivotal regulatory role in immune homeostasis, immune privilege, and self-tolerance. FasL, therefore, has been extensively exploited as an immunomodulatory agent to induce tolerance to both autoimmune and foreign antigens with conflicting results. Difficulties associated with the use of FasL as a tolerogenic factor ma...
