“Mask Herself Behind London Fog”: The Image of Early 20th-Century British Woman in Japanese Writer Noguchi Yonejiro`s Perception

The article was submitted on 13.05.2023.В центре внимания статьи – проблемы восприятия британских женщин в произведениях японских путешественников эпохи Мэйдзи, в частности, в работах японского писателя Ногути Ёнэдзиро. Было выявлено, что развитие контактов между Японией и Британией в заданный период стало причиной поездок японских подданных на Британские острова либо для знакомства с передовым британским опытом в экономической сфере, либо прохождения обучения в университетах. Участники путешествий 50–70‑х гг. XIX в. – студенты, политики и историки – оставили впечатления в виде записей и дневников, в которых затрагивали в том числе и гендерный вопрос: положение британских женщин, отношение к ним со стороны мужчин. Замечания очевидцев стали основой – «предобразом» – для заметок последующих путешественников. В дальнейшем подписание «Договора о Торговле и Мореплавании между Великобританией и Японией» в 1894 г. и трансформация отношений между государствами на равноправных началах к началу XX в. сделали практику путешествий доступной для обычных подданных. В этот период на Туманном Альбионе оказались не только студенты, но и преподаватели английского языка и писатели. Так, писатель Ногути Ёнэдзиро (1875–1947) прибыл в Британию в ноябре 1902 г. для публикации сборника стихотворений «С Восточного моря» на английском языке. На основе источников пребывания Ногути в Лондоне – автобиографии и сборника «13 лет Британии и США» – авторы статьи делают попытку сконструировать образ британской женщины во время первой поездки писателя. Помимо вышеупомянутого «предобраза», образ британской женщины в восприятии Ногути Ёнэдзиро базировался на девятилетнем опыте проживания писателя в Америке с 1893 по 1902 гг. и непосредственной коммуникации с британками в Лондоне. Ногути описывал их социальное положение, стиль, манеры. Тем не менее, замечания писателя мало отличались от представлений британцев того времени о соотечественницах и были стереотипными по своей сути.The article focuses on the problems of British woman perception in Japanese Meiji travellers` works, in particular, in the works of Japanese writer Noguchi Yonejiro. It was stated that relation development between Japan and Great Britain at that time had caused Japanese national`s trips to the British Isles in order to learn about advanced British experience in economic sphere or accomplish university training. 1850–1870s travellers, such as students, politicians, historians, left their impressions in the form of notes and diaries which touched upon, aside from other aspects, gender issues, for instance, British women social position and men attitude towards them. Their remarks had become the basis – “pre-image” – for future travellers` notes. Later on, the signing of “The Anglo-Japanese Treaty of Commerce and Navigation” in 1894 and relation transformation on equal principles between sides by the early 20th century made travels accessible to ordinary Japanese nationals. During that time not only students, but also the English language teachers and writers went to Great Britain. To exemplify, writer Noguchi Yonejiro (1875–1947) came to the British Isles in November 1902 to publish anthology “From the Eastern Sea” in English. Based on the sources of Noguchi`s stay in London, like autobiography and “13 Years of Great Britain and America” compilation, authors of this article try to construct a British woman image during writer`s first trip. Apart from abovementioned “pre-image”, Noguchi Yonejiro`s perception was based on his nine-year-stay in America from 1893 to 1902 and faceto-face communication with British women in London. Noguchi described their social position, style and manners. Nevertheless, writer`s remarks slightly differed from British perceptions of that time and were stereotypical in fact

Investigation of the effect of preliminary modification of solutions on the properties of precipitated hydrated zirconium oxides

In this study, hydrated zirconium oxides and yttrium stabilized zirconia powders were synthesized by precipitation. Influence of preliminary solution modification, namely preliminary heating of the solutions and the addition of sulfate ions was investigated. It is shown that the addition of sulfate ions leads to a decrease in the size of aggregates and an increase in the specific surface area of the particles. The greatest increase in the specific surface area was observed during precipitation of a preliminary heated solution with the addition of sulfate ions. © Published under licence by IOP Publishing Ltd.Ministry of Education and Science of the Russian Federation, Minobrnauka: 14.581.21.0028, RFMEFI58117X0028Research and DevelopmentThe work was supported by Act 211 Government of the Russian Federation, contract № 02.A03.21.0006.The study was financially supported by the Ministry of Education and Science of the Russian Federation within the framework of subsidizing agreement of October 23, 2017 (No. 14.581.21.0028, unique agreement identifier RFMEFI58117X0028) of the Federal Target Program “Research and development in priority directions of the progress of the scientific and technological complex of Russia for the years 2014–2020.” 5.

INFLUENCE OF THE CALCINATION TEMPERATURE OF ZIRCONIUM DIOXIDE ON THE PROPERTIES OF CERAMICS

Samples of zirconium oxide were synthesized and ceramics were made on their basic. It has been studied that a decrease in the calcination temperature of zirconium dioxide leads to an increase in the density, strength and hardness of ceramics.Данная работа выполнена при поддержке совета по грантам Президента Российской Федерации СП-2022

The Effect of Synthesis Conditions of Layered Gadolinium-Terbium Hydroxides on the Properties of Hybrid Phosphor Powders

In this work, hybrid phosphors powders based on layered Gd-Tb nitrate hydroxide, synthesized by controlled double-jet precipitation, as a result of intercalation of terephthalate ions, were obtained. The influence of the pH value of the synthesis on the properties of hybrid phosphor was studied

INFLUENCE OF THE SALT BACKGROUND ON THE PROPERTIES OF LAYERED GADOLINIUM HYDROXONITRATES, OBTAINED BY THE PRECIPITATION METHOD AT A CONSTANT VALUE OF PH

The work shows that the salt background has a significant effect on the process of precipitation of gadolinium hydroxonitrate: at a salt concentration below 5 M, the formation of particles occurs in a layer-by-layer buildup mode; at a concentration above 5 M, layered build-up does not occur. The properties of gadolinium hydroxonitrate particles are also largely determined by the nature and concentration of the salt background

BULK AND GRAIN BOUNDARIES CONDUCTIVITES OF LaYO3:CAO IN WET AND DRY AIR

Impedance spectroscopy was used to measure the conductivity of La1-x/2Y1-x/2CaxO3-α (x=0.1-10) at T=700-200оС and pH2O = 0.04-2.5 kPa. The bulk and grain boundaries conductivities were separated over the entire temperature range. It is found that the bulk and grain boundaries conductivities depend on the temperature and the wet of air.The highest proton conduction has been detected in the solid solution ofLa0.985Y0.985Ca0.03O3-α under wet air (pH2O=2.5kPa)

STUDY OF THE EFFECT OF THE VALUE OF PH ON THE SHAPE AND SIZE OF ZIRCONIUM DIOXIDE PARTICLES STABILIZED WITH A MIXTURE OF REE

The work is aimed at investigating the pH value of precipitation on the size and shape of zirconium dioxide particles stabilized with a mixture of REE. It is shown that an increase in the pH value leads to a decrease in the average particle size, when the particle shape becomes more rough
