Use of X-ray microanalysis for study of cation distribution in potassium deficient pumpkin roots
Acta Societatis Botanicorum Poloniae, 2014 Ice slices of root tissues were investigated by X-ray microanalysis. It is shown that the cytoplasm of the meristematic and differentiated cells of potassium dificiest roots maintains a high potassium level.

An Alternative Cure: The Adoption and Survival of Bacteriophage Therapy in the USSR, 1922–1955
Journal of the history of medicine and allied sciences, 2018 :Felix D'Herelle coined the term bacteriophage in 1917 to characterize a hypothetical viral agent responsible for the mysterious phenomenon of rapid bacterial death. While the viral nature of the "phage" was only widely accepted in the 1940s, attempts to

Effects of clouds on the radiative heat exchange in the atmosphere.
Geofísica Internacional, 1975 Las nubes son los principales reguladores del flujo radiativo. A su vez las nubes mismas están sujetas a efectos directos e indirectos de la radiación. Los efectos directos se producen mediante absorción y emisión de radiación por las nubes.
