    Notes: Abstract Atmospheric aerosols are a crucial link in the physical processes, involved in the formation and growth of precipitating clouds. Extensive aerosol measurements in surface air and in the lower troposphere were made at inland and coastal stations of different regions in India. At inland stations, the hygroscopic fraction of the total aerosol content is found to be a useful characteristic for distinguishing between the monsoon and summer airflow, as well as an indicator for a good or a badly developed monsoon. At coastal stations, however, this feature is not observed. Measurements as a function of height brought out that the aerosol varied widely in air over different seasons. During monsoon, the hygroscopic fraction was found highest at the cloud base level and was closely linked to the development of rain. Details of these investigations are presented.

    Notes: Summary Aircraft observations were made on cloud droplet size distribution in 19 cases of seeded warm cumulus clouds in three meteorologically different regions. An examination of the data suggested the following: (i) In all the 5 cases at Bombay (maritime), and in 6 out of the 7 cases at Poona (modified maritime) the values of median volume diameter, maximum cloud droplet size and liquid water content showed increase after seeding as compared to what they were before. The increases noticed in the median volume diameter ranged up to 48% at Bombay and 478% at Poona. The liquid water content and the maximum droplet size respectively increased upward of 56% and 25% at Bombay and 60% and 31% at Poona. (ii) In 4 out of the 7 cloud cases at Rihand (continental), the values of the parameters referred to above showed increase. The median volume diameter increased up to 372%. The liquid water content and the maximum droplet size increased upward of 160% and 66% respectively. (iii) In the cloud cases wherein the values of the parameters decreased after seeding, the decreases noticed ranged up to 94%. (iv) More unstable conditions prevailed on the days when the seeded clouds showed visible rain than on the days when they did not.

    Notes: Abstract  We describe a case of diabetic muscle infarction which had atypical features of hyperintensity of the affected muscle on T1-weighted images. Biopsy was performed which revealed diffuse extensive hemorrhage within the infarcted muscle. We believe increased signal intensity on T1-weighted images should suggest hemorrhage within the infarcted muscle.
