We successfully demonstrate a record real-time transmission over 3600-km G.652.D fiber with at least 7.9-dB OSNR margins using commercially available 200-Gb/s PDM-QPSK transponders, which reserves more than 3-dB engineering link budget for each 100-km span.

Viral Hepatitis B, C and D (Parenteral Transmission).
Abstract: Viral hepatitis B, C, and D are major global health problems characterized by chronic liver infection and significant morbidity and mortality. These hepatotropic viruses are primarily transmitted through parenteral routes, including contaminated blood products, unsafe injections, intravenous drug use, and perinatal exposure.

In 1978-79 a single-source outbreak of hepatitis C occurred in 2533 women who had received virus-contaminated anti-D immunoglobulin. Children and husbands of 74 women with self-limited, and of 86 women with chronic, hepatitis C were followed up for over 10-15 years.

D-C transformers and transmission
Electrical Engineering, 1938T. C. Lennox and E. V. De Blieux in a very interesting paper “A D-C Transformer,” published in the Transactions section of the September 1938 issue of Electrical Engineering on pages 554 to 558, describe a device using a mechanical commutator in conjunction with stationary transformers to transform direct current from one voltage to another.

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.

Preferential in-utero transmission of HIV-1 subtype C as compared to HIV-1 subtype A or D
AIDS, 2004To determine whether different HIV-1 genotypes present in a single cohort, in Dar es Salaam, Tanzania, showed differences in timing for transmission from mothers to their infants.We determined the maternal viral load, transmission time, and the HIV-1 envelope (env) subtype of 253 HIV-1-infected infants enrolled in a randomized double-blind placebo ...

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.

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.
