Abstract Background and Objectives: The aim of this study was to determine the hepatitis C virus (HCV) infection rate of recipients of different batches of anti‐D immunoglobulin associated with an outbreak of HCV infection which occurred in 1977 and its relationship to the polymerase chain reaction (PCR) status of the implicated

Operation and Control of HV D-C Transmission
IEEE Transactions on Power Apparatus and Systems, 1964The special requirements on control of inverters for HV (high-voltage) d-c transmission have led to a special control system, which is described. Co-operation between regulators at each end of the transmission is necessary in reducing the consequences of disturbances in the converters.

Performance Evaluation of S+C+L-Band Optical Transmission over G.652.D and G.654.E Fibers
Conference on Lasers and Electro-Optics, 2022We evaluate the performance of 150-nm SCL-band optical transmission over 1280-km G.652.D and G.654.E fibers. By optimizing power allocation and system configuration, SCL-band long-haul transmission enables the same performance as commercial C-band system.

Abstract We carried out experiments with virus infected females on the horizontal transmission of Drosophila C virus on artificial culture medium and under controlled conditions. The numerical results made it possible to build up an empirical model.

For a real band-limited periodic signal, there are reconstruction formulas that realize the ideal discrete-to-continuous (D/C) conversion within one period of the signal. However, the previous results may not be suitable for general complex band-limited periodic signals.

Submarine cable for 100-kv D-C power transmission
Electrical Engineering, 1954A 100-KV D-C submarine cable, 60 miles long and weighing approximately 1,000 tons, has been laid in the Baltic Sea and will be used for transmission of about 20,000-kw d-c power between the mainland of Sweden and the Isle of Gotland.

High-Voltage D-C Transmission: General Background and Present Technical Status
IEEE Transactions on Power Apparatus and Systems, 1964The keys to practical application of high-voltage (HV) direct current for power transmission are the rectifier and inverter, which supply the high voltage required for terminals of the d-c line. The grid-controlled mercury-arc tube with grading electrodes has proved to be a suitable valve in such converters.

IEEE Transactions on Automatic Control, 1978
A new algorithm, which is an extension of [1, algorithm II], is presented to determine the transmission zeros of the system \dot{x}=Ax+Bu, y=Cx+Du denoted by (C,A,B,D) . The algorithm is based on the observation that for nondegenerate (C,A,B,D) systems, the set of transmission zeros of (C,A,B,D) are contained in the finite eigenvalues of the closed ...

Contributions to Mineralogy and Petrology, 1974
Ten specimens of plagioclase feldspars (An100 to An25) have been examined by transmission electron microscopy using dark field and direct lattice imaging. The specimens are classified into two groups: (i) those that have been quenched from the melt (synthetic An100, An95, An66 and An50) and (ii) those that have been cooled relatively slowly (An94, An77,

The HIVNET 012 trial in Uganda showed that mother-to-child transmission (MTCT) of HIV-1 can be prevented by providing pregnant women and their infants with a single dose (SD) of the antiretroviral drug nevirapine (NVP). Safety and efficacy of 1- or 2-dose NVP prophylaxis for prevention of MTCT have been documented in other studies.
