Feat ures of continuing formati on of stochastic cult ure of schoolchildren in the conditions of dista nce learning

The article describes the essence of continuity in the formation of a stochastic culture of students in the conditions of distance learning. The author’s definition of the concept “continuity in the formation of stochastic culture of students of a general education school in the conditions of distance learning” is given. There are the basic conditions of a teacher’s possession of the highest level of stochastic culture, due to which the formation of an integral personal quality, which is a generalized indicator of stochastic competence, takes place in schoolchildren. Modern information and communication technologies used in a series of developed distance classes in statistics, combinatorics and probability theory for grade 11 students are proposed. These ICT contribute to the successive formation of elements of stochastic culture in the conditions of distance learning. The article emphasizes that the use of ICT in teaching stochastics is an effective methodological tool, through which significant results can be achieved in the educational process.

PHOTOCATALYTIC OPTIMIZATION OF MR DYE BY K-ZnO AND ZnO CATALYSTS UNDER VISIBLE IRRADIATION

The lucubration on the visible light methyl red (MR) degradation using K-ZnO and undoped ZnO photo catalyst was investigated. The successive formation of K-ZnO was ascertained by several techniques such as scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), and UV-Visible spectrophotometer and solid state UV-Vis band gap energy determination by comparing the Kubelka-Monk equation with Tauc equation and the energy band gap was calculated to be 3.28ev. The influence of reaction variables such as MR concentration, reaction pH, catalyst loadings and temperature have been investigated for both process. The kinetics model was developed for both doped and undoped ZnO photocatalyst using pseudo first and second order kinetics, the result indicated that both doped and undoped ZnO followed pseudo first order kinetics due to higher correlation coefficient (R2) value of 0.985 and 0.922 with rate constant (k) of 0.026 min-1 and 0.062 min-1, respectively. Based on the rate constant value (k) obtained at different reaction temperatures, the Arrhenius expression was derived. The derived activation energy (Ea) for the degradation of MR by K-ZnO photocatalysis was 32.109x103JK-1. The optimum condition for K-ZnO showed nearly complete degradation (95%) of the dye molecules with slightly higher degradation efficiency compares to ZnO (91%).

CONTINUITY IN THE CONTENT OF TEACHING PROJECT AND RESEARCH ACTIVITIES OF SCHOOLCHILDREN, BACHELOR'S AND MASTER'S STUDENTS ON THE EXAMPLE OF THE DISCIPLINE “FOREIGN LANGUAGE”

The article is devoted to the consideration of the process of the successive formation of metasubject results in the framework of project / research activities of students in the context of learning foreign languages. In this regard, the requirements for the degree of formation of metasubject skills formed within the subject of "Foreign language" at various levels of education and taking into account the stages of project activity (including research project) – goal setting, organization and planning, implementation, reflection, presentation. The article describes a project conducted by the Department of foreign languages and linguodidactics of Irkutsk state University called "the Future in the project", implemented in the framework of the subjects "Methodology of teaching foreign languages" at the University and "Foreign language" at school in order to implement the continuity of the content of teaching project/research activities of students at different levels of education.

Transition metal-free approach to azafluoranthene scaffolds by aldol condensation/[1+2+3] annulation tandem reaction of isocyanoacetates with 8-(alkynyl)-1-naphthaldehydes

A transition metal-free aldol condensation/[1+2+3] annulation reaction of isocyanoacetates with 8-(alkynyl)-1-naphthaldehydes has been developed for the general synthesis of azafluoranthenes. This domino reaction enables successive formation of three new bonds...

Pyrazoles: ‘one-pot’ synthesis from arenes and carboxylic acids

A rapid and efficient method for ‘one-pot’ synthesis of pyrazoles from (hetero)arenes and carboxylic acids via successive formation of ketones and β-diketones followed by heterocyclization with hydrazine has been developed.

Removal of pyrazinamide and its by-products from water: Treatment by electro-Fenton process and feasibility of a biological post-treatment

This paper reports a study on oxidative degradation and mineralization of pyrazinamide in an aqueous medium at pH = 3 and room temperature (≈ 19 °C) by the electro-Fenton process, using carbon felt as a cathode and platinum as an anode. The degradation/mineralization is assessed by the chemical oxygen demand by analyzing applied current intensity and concentration of Fe2+ catalyst. Thus, the main objective is to determine the optimal values of these parameters. Some stable intermediate products have been identified using highperformance liquid chromatography and liquid chromatography tandem mass spectrometry, which show the successive formation of the aromatic/cyclic organics and aliphatic intermediates. The second part of this work corresponds to the study of the biodegradability giving by the ratio: BOD5/COD during the mineralization of pyrazinamide by EF in order to examine the possibility of combining electro-Fenton with a biological posttreatment.

Shaping the National Body: Physical Education and the Transformation of German Nationalism in the Long Nineteenth Century

The following article reconstructs the curricular story of physical education between the Prussian prohibition (1820) and reintroduction (1842) and broad dissemination of ‘gymnastic exercises’ between 1842 and 1871 and its full implementation around 1900 in Germany, focusing on the interrelation between constitutional reforms, nationalism and the development of a state-directed educational system, directed towards making the loyal future citizens. The successive formation of a German nation-state is being understood as the historical context of the implementation of gymnastics in the school curriculum; a process that in its success depended on the rise of nationalism as a dominant political ideology in the course of the nineteenth century.

Stereospecific reductive coupling polymerization of bis(benzylic gem-dibromide)s via formation of a trans-CC bond

Stereospecific polymers are constructed by stereospecific reductive coupling polymerization of bis(benzylic gem-dibromide)s via successive formation of a trans CC bond.

TRACING A CULTURAL MEMORY: COMMEMORATION OF 1857 IN THE DELHI DURBARS, 1877, 1903, AND 1911

ABSTRACTThe three imperial durbars held in Delhi for the coronation of British monarchs as the rulers of India were gatherings of royalty, administration, and the military, organized in the years 1877, 1903, and 1911. As impressively invented, improvised, and self-styled orientalist representations of the late Victorian tradition, these durbars were pageants of power, prestige, and authority, creations of their organizing viceroys: Robert Lytton (1877), George Curzon (1903), and Charles Hardinge (1911). But, as this article shows, they were also commemorative exhibitions of the triumphant memory of the event of 1857 (variously called the Indian Mutiny, Sepoy war, War of Independence), especially in Delhi which had to be emphasized regularly for perpetuating myths about British superiority and invincibility. Spread over a period of thirty-five years, these rituals of commemoration were performed through four illustrative choices. These were the selection of site, selection of mutiny veterans as participants, the construction of mutiny memorials, and contribution to the growth of mutiny pilgrimage tours. Drawing attention to the successive formation of 1857 as a seminal ‘cultural moment’ through its periodic commemoration, the present article brings to focus the enduring significance of the event for the British empire in India, which had to be re-visited time and again for purposes of legitimation and cultural appropriation.
