Green Spaces of Omsk in Late 19th — Early 20th Centuries: Projects and Initiatives for Greening City

Beijerinck and the bioluminescent bacteria: microbiological experiments in the late 19th and early 20th centuries.

Microbiological research in the days before specialized equipment, or even electricity, required a great deal of ingenuity. The revival of 90-year-old bioluminescent bacteria from Beijerinck's laboratory in Delft prompted a review of his work with these microorganisms and revealed their use in simple techniques for the investigation of, among other things, sugar metabolism in yeasts, oxygen gen...

Research on iodine deficiency and goiter in the 19th and early 20th centuries.

In 1811, Courtois noted a violet vapor arising from burning seaweed ash and Gay-Lussac subsequently identified the vapor as iodine, a new element.

Hospital admissions for peptic ulcer and indigestion in London and New York in the 19th and early 20th centuries.

The occurrence of peptic ulcer increased rapidly in all Western countries from the 19th to the 20th century, attributed to a possible epidemic of Helicobacter pylori, a new pathogenic strain, or a change in host susceptibility. The early trends in hospital admissions for peptic ulcer and dyspepsia in London and New York during the 19th century are reviewed to test these hypotheses.
