13. Modelo e analise do motor de indução bifasico assimetrico com o estator conectado em T
This dissertation has the aim of determining a mathematical model for asymmetrical two-phase induction motor with T-connected stator windings and to investigate some properties such as free acceleration, steady-state torque-speed characteristic and steady-state currents. This motor is designed to operate from supply of two phases and neutral, and a particula

14. INDUCTION MOTOR REDUCED ORDER TRANSFER FUNCTIONS / FUNÇÕES DE TRANSFERÊNCIA DE ORDEM REDUZIDA PARA MOTORES DE INDUÇÃO
Among the electric machines used in industrial system presently one can highlight the induction motors, not only for its large number but also due to the increasing capacity of such machines. Motors, converter and control circuits can be combined under varied ways highlighting the necessity of an adequate modelling for the system as a whole. Based on informa

15. Formic Hydrogenlyase Induction as a Basis for the Eijkman Fecal Coliform Concept
Many Enterobacter species recovered from a relatively unpolluted freshwater stream had the capacity to produce gas from glucose, lactose, and formate at 44.5 C. Composition of the evolved gas was shown to be CO2 and H2, which suggested that the enzyme system formic hydrogenlyase functions as the basis for the Eijkman fecal coliform concept. It is postulated

16. I-E/I-C region-associated induction of murine gamma interferon by a haplotype-restricted polyclonal T-cell mitogen derived from Mycoplasma arthritidis.
Cell-free supernatants from cultures of Mycoplasma arthritidis induced significant levels of interferon when cocultured with murine splenic cells. On the basis of physicochemical characteristics and antibody neutralization studies, the antiviral substance was identified as gamma interferon. Use of inbred and congenic mouse strains established that splenic ce

17. INDUCTION OF STAPHYLOCOCCAL PENICILLINASE BY BENZYLPENICILLIN: EFFECT OF pH, CONCENTRATION OF FERROUS ION AND INDUCER, AND DURATION OF EXPOSURE OF CELLS TO INDUCER
Leitner, Felix (Michael Reese Hospital and Medical Center, Chicago, Ill.), Helen M. Sweeney, T. F. Martin, and Sidney Cohen. Induction of staphylococcal penicillinase by benzylpenicillin: effect of pH, concentration of ferrous ion and inducer, and duration of exposure of cells to inducer. J.

18. CELLS INVOLVED IN THE IMMUNE RESPONSE, XIII. THE NATURE OF THE CELLULAR INTERACTIONS RELATING ANTIBODY FORMATION AND IMMUNOLOGIC TOLERANCE: A UNIFIED HYPOTHESIS
The various cells and cell pathways involved in the induction of the primary humoral immune response have been discussed from the point of view of the unitary, as opposed to the multiple, pathway concept. The immunocompetent cells made unresponsive in the immunologically tolerant animal and the cells capable of responding with antibody formation were conside

19. Agrobacterium tumefaciens Conn IV. Bacteriophage PB21 and Its Inhibitory Effect on Tumor Induction
Strain B2 of Agrobacterium tumefaciens Conn produces plaques when seeded against strain B6-806 of the same organism. From such a plaque, a highly virulent bacteriophage was obtained by use of D'Herelle's technique of selecting for virulent phage. On nutrient agar, this phage, PB21, produced large clear plaques which did not overgrow. Plaques produced on a gl

20. Peptidyl transferase inhibition by the nascent leader peptide of an inducible cat gene.
The site of ribosome stalling in the leader of cat transcripts is critical to induction of downstream translation. Site-specific stalling requires translation of the first five leader codons and the presence of chloramphenicol, a sequence-independent inhibitor of ribosome elongation. We demonstrate in this report that a synthetic peptide (the 5-mer) correspo

21. Statin-induced muscle damage and atrogin-1 induction is the result of a geranylgeranylation defect
Statins are widely used to treat hypercholesterolemia but can lead to a number of side effects in muscle, including rhabdomyolysis. Our recent findings implicated the induction of atrogin-1, a gene required for the development of muscle atrophy, in statin-induced muscle damage. Since statins inhibit many biochemical reactions besides cholesterol synthesis, w

22. The abscisic acid induction of a novel peroxidase is antagonized by cytokinin in Spirodela polyrrhiza L.
The growth regulator abscisic acid (ABA) can be used to induce dormant bud structures (turions) in the duckweed Spirodela polyrrhiza L. In this paper we show that during this process, ABA rapidly induces elevated levels of mRNA transcripts encoding a novel basic peroxidase. In addition, we show that in the presence of the cytokinin kinetin the maintained inc

23. Exposure to crosslinked IgD induces receptors for IgD on T cells in vivo and in vitro.
IgD is a surface immunoglobulin, which is coexpressed with IgM on greater than 90% of mature B cells, but its levels in serum are extremely low compared to those of IgM. It role as a surface receptor has been reemphasized by our recent findings that IgD receptors are induced on helper T cells by exposure to IgD and that such cells have immunoaugmenting prope

24. Cycloheximide induction of xenotropic type C virus from synchronized mouse cells: metabolic requirements for virus activation.
The information for type C RNA viruses is genetically transmitted within the cellular DNA of the normal mouse cell. These viruses can be induced after exposure of cells to two classes of chemicals, inhibitors of protein synthesis and halogenated pyrimidines. The metabolic requirements for activation of one endogenous virus of BALB/c mouse cells by representa
