[The financial activity of district hospitals of the Irkutsk general-governorship in the end of XIX century].

The article presents results of the study of archive sources and reference publications. The unknown facts of subsidization of district hospitals of the Irkutsk general-governorship, items and amount of current and supernumerary expenses and sources of financial allocations are revealed. The scope of financial accountability made up by directors and hospital supervisors, office and council of hospitals as well care of charge of patients is impressive.

[The comparative evaluation of heterogeneity of urban and rural population aging at the regional level].

The article considers the process of population aging, which is evidently specific in economically developed countries for last quarter of the XX century. The increasing of population size older than able-bodied age in urban and rural population in the Irkutsk Oblast that is demonstrated by aging coefficient dynamic. In all studied territories increasing of this coefficient is revealed that characterizes transition of aging process in most areas of residence of urban and rural population to the level of III-IV stages (old and deeply old population).

[The Irkutsk department of the Society of struggle with contagious diseases: history of establishment, structure, tasks, sources of financial appropriations].

The article considers chronologies of events of the opening in the city of Irkutsk of the Irkutsk branch of the Society of struggle with contagious diseases, located in St.Petersburg. It is emphasized that socially necessary need for protection against contagious diseases contributed to organization of the Branch of the Society of Struggle with Contagious Diseases.

Direct Probing of Vibrational Interactions in UiO-66 Polycrystalline Membranes with Femtosecond Two-Dimensional Infrared Spectroscopy.

UiO-66 is a benchmark metal-organic framework that holds great promise for the design of new functional materials. In this work, we perform two-dimensional infrared measurements on polycrystalline membranes of UiO-66 grown on c-sapphire substrates. We study the symmetric and antisymmetric stretch vibrations of the carboxylate groups of the terephthalate linker ions and find that these vibrations show a rapid energy exchange and a collective vibrational relaxation with a time constant of 1.

Nature of hydrated proton vibrations revealed by nonlinear spectroscopy of acid water nanodroplets.

We use polarization-resolved femtosecond pump-probe spectroscopy to investigate the vibrations of hydrated protons in anionic (AOT) and cationic (CTAB/hexanol) reverse micelles in the frequency range 2000-3500 cm-1. For small AOT micelles the dominant proton hydration structure consists of H3O+ with two OH groups donating hydrogen bonds to water molecules, and one OH group donating a weaker hydrogen bond to sulfonate. For cationic reverse micelles, we find that the absorption at frequencies >2500 cm-1 is dominated by asymmetric proton-hydration structures in which one of the OH groups of H3O+ is more weakly hydrogen-bonded to water than the other two OH groups.
