Intensification of copper and chromium (VI) removal from solutions in magnetic field

Possibility to replace mechanical stirring by the magnetic field induced one was shown for considerable intensification of Си (II) and Cr (VI) ion biosorption by the yeast Saccharomyces cerevisiae 1968. Combined method of metal ion recover, including Си (II) and Cr (VI) ion sorption by yeast Saccharomyces cerevisiae and Си (II) and Сг (VI) cementation on a surface of a steel matrix, is tested in case of magnetic field induced stirring.Рассмотрена возможность использования магнито-гидродинамического перемешивания (вместо механического перемешивания) для интенсификации биосорбции ионов Си (II) и Cr (VI) при помощи дрожжей Saccharomyces cerevisiae 1968. В работе проверяется комбинированный метод извлечения ионов металла, который состоит из сорбции ионов Си (II) и Cr (VI) дрожжами Saccharomyces cerevisiae и цементации ионов Си (II) и Сг (VI) на поверхность стального элемента в случае перемешивания индуцированным магнитным полем.В даній роботі розглядається можливість використання магніто-гідродинамічного перемішування (замість механічного перемішування) для інтенсифікації біосорбції іонів Си (II) та Сг (VI) за допомогою дріжджів Saccharomyces cerevisiae 1968. В даній роботі перевіряється комбінований метод видалення іонів металу, який включає в себе сорбцію іонів Си (II) та Сг (VI) дріжджами Saccharomyces cerevisiae та цементацією іонів Си (II) та Сг (VI) на поверхню стального елементу, у випадку перемішування індукованого магнітним полем

The impact of visualization tools in distance english language learning: the experience of the russian university teachers

The article is aimed at a detailed examination of the prerequisites for the introduction of visual content into the educational process in the foreign language course during distance learning and at defining a list of prerequisites for its successful processing by students. The article proves that the search for new trends and approaches to education leads to new goals and new types of knowledge. All innovations in higher education contribute to the formation of a new image of future professionals. The relevance of the problems of higher education technologization is associated with the countless number of innovations, among which the authors single out the visualization of educational information in distance learning. The article shows the importance of visualization in distance education. The given technology includes both visual presentations of information and the development of visual thinking during the educational process. Educational material and an effective visual teaching method allow making the educational process interesting and nonstandard and increasing students' motivation to learn English. Thus, the visualization of educational information is a tool for distance learning technology. The article identifies the preferable visualization tools based on the survey of students based on the results of the use of visualization in distance English language learning. According to the summary of the results of distance English language learning, it is proposed to divide the visualization process into several stages
