If there were enzymatically inactive B subunits in a solution containing lactate dehydrogenase (LD) B4 prepared from the hemolysates of heterozygous individuals with LD-B subunit deficiency, the inactive subunits would compete with normal subunits for antibodies to the B4 subunit. Using the activity of normal LD-B4 as an index, we could ascertain the proportion of free antigen (LD-B4) and antib...

489 Abstract: The presence and distribution of Griffonia Simplicifolia I-B4 (GSA I-B4) and Calcitonin Gene Related Peptide (CGRP) were studied in the nodose ganglion (NG) (inferior ganglion of the vagus nerve), sphenopalatine ganglion (SPG) and superior cervical ganglion (SCG) of the rat. GSA I-B4 labeling was found in all ganglia tested. Neither SPG nor SCG cell bodies stained with CGRP were u...

In this paper, a new topology for boost Z-source inverterbased on switched-inductor cell is proposed. The operating modes of the proposed inverter are analyzed and also a suitable control method to generate the trigger signals of the inverter is presented. Having a common earth between the input source and inverter and capability to generate a higher voltage gain by using lower amounts of the d...

Recently, the evolution of single phase multilevel inverters has been escalation due to its preference over traditional one. In this paper proposed a new topology of single phase Nine level inverter with less number of power elements for grid connection. In this proposed inverter have ten switches and their switches operate with fundamental frequency. The proposed inverter produced nine level o...

 When utilized at low amplitude modulation indices, existing multilevel carrier-based PWM strategies have no special provisions for this operating region, and several levels of the inverter go unused. This paper proposes some novel multilevel PWM strategies to take advantage of the multiple levels in both a diode-clamped inverter and a cascaded Hbridges inverter by utilizing all of the levels ...

The paper describes an investigation of fault tolerant control strategies for permanent magnet synchronous motor (PMSM) driven by a fault-tolerant inverter. The inverter is a topology-modified inverter with fault-tolerant capability, which can be configured as the standard 3-phase 6-switch inverter and reconfigured as 3-phase 4-switch or 2-phase 4switch inverter under the fault condition. By an...

There is strong trend in the photovoltaic (PV) inverter technology to use transformer less topologies in order to acquire higher efficiencies. The general function of multilevel inverter is to synthesis desired voltage from solar source. This inverter has advantageous of industrial applications. The use of converters will increase losses and cost in conventional methods. The proposed seven leve...

A six-level inverter system for an open-end winding induction motor drive is presented in this paper. Multilevel inversion is achieved by feeding an open-end winding induction motor with a 3-level inverter from one end and a 2-level inverter from the other end of the motor. The 3level inverter used in the proposed drive, is realized by cascading two 2-level inverters. The combined inverter syst...

In this paper, a new family of single-stage high step-up boost voltage inverter based on transformer is proposed, called T-Z source inverters. By replacing two inductors in the classical Z-source inverter with two transformer, the proposed inverter produces a very high boost voltage gain when, the turn ratio of the transformer is larger than one. Compared to the trans-Z source inverter, the pro...
