a total of 711 beta-hemolytic streptococci were isolated from throat cultures of patients during 1970-73. these strains were grouped in parallel by the precipitin and bacitracin paper disk method. the former method was estab­lished as the standard by which the bacitracin technique was compared. the difference in results was about 5.67%. the greatest error (5.4%) was seen with non-group a strain...

Energy consumption in Iran is a subject of debate. Some may think that oil is cheap in Iran and thus no need for this kind of research. This simple minding is erroneous first because Iran subsidizes billion dollars each year for the imported diesel fuel specially for agricultural use and second because energy studies reveal the degree of professionally using the technology. We can easily find t...

We present a new long-duration parallax event from the OGLE-II database, sc5 2859, which has the second longest time-scale ever identified (tE = 547.6 +22.6 −7.8 days). We argue that both the lens and source reside in the Galactic disk, making event sc5 2859 one of the first confirmed examples of so-called disk-disk microlensing. We find that the source star is most probably located at a distan...
