RESUMO
The article deals with the results of an anonymous testing of HIV infections in Yugoslavia. The presence of anti-HIV-antibodies was examined in the blood of pregnant patients, randomly selected, in a Ward where about 3000 artificial abortions were carried out in the first trimester of pregnancy in a six-month period. On the basis of the obtained results one patient of 177 tested women was infected by HIV virus. At the same time, it can be presumed that among 3000 pregnancies there were many anti-HIV positive persons. It should be emphasized that the staff was not aware of HIV infection in one patient, and that in Yugoslav epidemiological conditions a HIV infected person could unexpectedly be detected without preliminary findings and data.

The authors followed up a pregnant woman with Addison's disease. Prior to, and throughout pregnancy, she received hydrocortisone in daily doses of 20 mg. The basic disease did not deteriorate during pregnancy. The pregnancy was terminated in the 41st week of gestation by induced labour. The infant's birth weight was below the 10th centile for the gestational age. Apgar score was 6. During the puerperium, the maternal basic disease got worse, requiring the increased substitution therapy. Both the mother and child discharged in good condition, on the 11th postpartal day.

An experimental device successfully upconverts ir radiation in the 3.2-5.0-microm wavelength range simultaneously to "visible" light at 0.80-0.88 microm, while preserving frequency coding and is thus applicable to ir spectroscopy. The 1.8-microm bandwidth of ir radiation that is upconverted without temperature or phase match tuning is the largest yet reported. The over-all system quantum efficiency of the upconverter/spectrometer system is 0.01% and could be improved to 0.4%.
RESUMO
Spectroscopic observations of the two stars near the pulsar CP 1919+21 are not sufficiently conclusive to permit an identification of either object with the source of the radio pulses. However, our most extensive series of photometric observations of a region of sky near the radio source position, which region includes the brighter of the two stars, suggests an approximately sinusoidal variation. It is significant that the period of the variation is double the period of the radio pulsations.
RESUMO
In stellar astronomy, the future of automation techniques lies in their application to the largest telescopes. In such a case, the cost of automation is small compared to that of the telescope project as a whole, and is well repaid in the savings in observing time. A "stand-alone" capability for manual operation in event of computer breakdown is usually provided for systems like this; an example is the 107-inch (272-cm) telescope under construction at the McDonald Observatory of the University of Texas, which will be associated with an IBM 1800 computer.
