“…64 Soil, for him resulted from the accumulation and cycling of humus (decaying organic matter), a decomposition process, in which bacteria and fungi played the central role. 65 By creating a place for microbiology in soil science during its formative period, Kostychev prepared the way for Vinogradskii's soil microbiology in the 1890s. Dokuchaev (1846Dokuchaev ( -1903 contributed most to the founding of scientific soil science.…”

In 1890, Sergei Nikolaevich Vinogradskii (Winogradsky) proposed a novel life process called chemosynthesis. His discovery that some microbes could live solely on inorganic matter emerged during his physiological research in 1880s in Strassburg and Zurich on sulfur, iron, and nitrogen bacteria. In his nitrification research, Vinogradskii first embraced the idea that microbiology could have great bearing on agricultural problems. His critique of agricultural chemists and Kochian-style bacteriologists brought this message to the broader agricultural community, resulting in an heightened interest in biological, rather than chemical methods to investigate soil processes. From 1891 to 1910, he directed the microbiological laboratory at the Imperial Institute of Experimental Medicine in St. Petersburg, Russia, where he expanded his chemosynthesis research to a broad investigation of the manifold significance of autotrophic organisms in soil processes. This work and that of his students attracted the serious attention of agricultural chemists and soil scientists in Russia and abroad, changing essentially the way they understood and investigated the role of microbes in the soil. His student, Vasilii Omelianskii, effectively integrated Vinogradskii's approach into Russian and Soviet, and international agricultural microbiology. Vinogradskii's activities in the late 19th century reflect the changes occurring more broadly in science. At that time, microbiologists such as Louis Pasteur, Eugenius Warming, and Martianus Beijerinck were contributing new laboratory methods and theoretical perspectives to incipient disciplines closely related to agriculture: ecology, soil science, and soil microbiology.

“…Good consistency between precise y-ray energies and coincidence relations lead to the establishment of the first excited state at 497 (3/2+) and the two isomeric states at 613 (7/2+) and 714 (1112-) keV respectively which correspond to the 499, 619 and 726 keV levels of ref. [8].…”

“…Apart from the earlier l15Sb decay and Coulomb excitation measurement [5-71, Ivanov et al [8] have studied this nucleus through the 1161n(p,n) reaction, using a NaI detector. They found isomeric states at 726 and 619 keV and measured the conversion coefficients of the two de-exciting transitions.…”

An in-beam study of excited states in 115Sn has been made through the reactions 115In(p,n)115Sn, 112Cd(α,n)115Sn, 115In(d,2n)115Sn, and 113Cd(α,2n)115Sn. A level scheme containing 21 levels is proposed on the basis of the following measurements: γ-ray energies and intensities, excitation functions, conversion electron intensities, γ-γ- and e-γ-coincidences and angular distribution of γ-rays. The position of an odd parity state above the h11/2- single particle state is discussed.
