Equilibrium phase formations below 600 K in the parts Ag2Te–FeTe2–F1.12Te–Ag2Te and Ag8GeTe6–GeTe–FeTe2–AgFeTe2–Ag8GeTe6 of the Fe–Ag–Ge–Te system were established by the electromotive force (EMF) method. The positions of 3- and 4-phase regions relative to the composition of silver were applied to express the potential reactions involving the AgFeTe2, Ag2FeTe2, and Ag2FeGeTe4 compounds. The equilibrium synthesis of the set of phases was performed inside positive electrodes (PE) of the electrochemical cells: (−)Graphite ‖LE‖ Fast Ag+ conducting solid-electrolyte ‖R[Ag+]‖PE‖ Graphite(+), where LE is the left (negative) electrode, and R[Ag+] is the buffer region for the diffusion of Ag+ ions into the PE. From the observed results, thermodynamic quantities of AgFeTe2, Ag2FeTe2, and Ag2FeGeTe4 were experimentally determined for the first time. The reliability of the division of the Ag2Te–FeTe2–F1.12Te–Ag2Te and Ag8GeTe6–GeTe–FeTe2–AgFeTe2–Ag8GeTe6 phase regions was confirmed by the calculated thermodynamic quantities of AgFeTe2, Ag2FeTe2, and Ag2FeGeTe4 in equilibrium with phases in the adjacent phase regions. Particularly, the calculated Gibbs energies of Ag2FeGeTe4 in two different adjacent 4-phase regions are consistent, which also indicates that it has stoichiometric composition.
This article is review and informative. A web application was created from a series of maps that provide the user with information about the 150-year history of the department of geodesy of Lviv Politechnic National University. With the help of maps, you can get the necessary information about the scientific-pedagogical and auxiliary staff of the department.
Транспортний сектор України потребує суттєвих змін у землекористуванні відповідно до міжнародних угод. Необхідно систематизувати поняття земель транспорту, проаналізувати тенденції щодо використання земель для таких цілей в розрізі власників землі та землекористувачів, а також окреслити перспективи розвитку землекористування транспортного сектора України. Відсоток аукціонів на які виносять землі транспорту залишається невеликим, оскільки землі транспорту не користуються попитом на земельних торгах. Це можна пояснити відсутністю фінансово-спроможних учасників аукціону серед українців, недостатню наповненість бюджетів та недостатнє висвітлення роботи аукціонів. Слід зауважити, що для Львівської області відсоток аукціонів для земель транспорту складає до 40% усіх аукціонів в Україні, що свідчить про розвиток транспортної галузі на території області.
The article is review and informative. A web application has been created from a series of maps that provide the user with information about the history of the Department of Cartography and Geospatial Modeling of Lviv Polytechnic National University. With the help of a series of maps, you can get the necessary information about the scientific-pedagogical and auxiliary staff of the Department of Cartography and Geospatial Modeling.The data was processed and a database was created in the Microsoft Excel spreadsheet editor, which was used to create an interactive web map of the scientific-pedagogical and auxiliary staff of the Department of Cartography and Geospatial Modeling of Lviv PolytechnicNational University.The methods of cartographic representation are described, namely, the method of localized icons and the method of cartograms, which were used when laying out interactive web maps. The entire algorithm for laying out, editing interactive web maps and creating the web application consisting of a series of such web maps is described step by step and in detail.As a result, the series of interactive web maps of employees of the Department of Cartography and Geospatial Modeling of Lviv Polytechnic National University, localized by place of birth, was obtained. Most of the teachers who worked or currently work at the Department of Cartography and Geospatial Modeling were born in Lviv Oblast and studied at Lviv Polytechnic Institute or Lviv Polytechnic National University.The result of the research is the web application with the series of maps: “Scientific-pedagogical and auxiliary staff of the TMPGM department”, “Scientific-pedagogical and auxiliary staff of the CGM department”, “Number of teachers of TMPGM and CGM departments by regions of Ukraine (as a percentage of the total number of teachers from Ukraine)”.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
