Room Of One's Own

This first serious attempt at an autobiographical accounting has forced me to sit still long enough to compile my thoughts about a long personal and scientific journey. I especially hope that my trajectory will be of interest and perhaps beneficial to much younger women who are just getting started in their careers. To paraphrase from Virginia Woolf's writings in A Room of One's Own at the beginning of the 20th century, “for most of history Anonymous was a Woman.” However, Ms. Woolf is also quoted as saying “nothing has really happened until it has been described,” a harbinger of the enormous historical changes that were about to be enacted and recorded by women in the sciences and other disciplines. The progress in my chosen field of study—the chemical basis of enzyme action—has also been remarkable, from the first description of an enzyme's 3D structure to a growing and deep understanding of the origins of enzyme catalysis.

Perfume encapsulates are widely used in commercial products to control the kinetic release of odorant molecules, increase storage stability and/or improve deposition on different substrates. In most of the cases, they consist of core-shell polymeric microcapsules that contain fragrance molecules. A current challenge is to design and produce polymeric materials for encapsulation that are both resistant and non-persistent. The selection of such eco-friendly formulations is linked to a deep understanding of the polymeric material used for encapsulation and its biodegradation profile. To collect this information, pure samples of capsule shells are needed. In this article we present an innovative quantification method for residual volatiles based on pyrolysis-GC-MS to enable validation of sample quality prior to further testing. The presented analytical method also led to the development of a robust and comprehensive purification protocol for polymers from commercial samples. Standard techniques are not suited for this kind of measurement due to the non-covalent embedding of volatiles in the 3D structure of the polymers. We demonstrated the confounding impact of residual volatiles on the estimated biodegradability of fragrance encapsulates.

Room Of One's Own

Woolf’s essays fall into many genres, including book reviews, literary criticism, biography, memoir, and occasional pieces. As a student of the essay and its history, she studied the form from Montaigne, Hazlitt, Pater, and Beerbohm and through their work she learned to make the essay her own, reinventing the genre to argue for a uniquely female and feminist perspective. Woolf’s deep understanding of the essay’s form, her drive to construct a female literary history and female narrative form, culminate in A Room of One’s Own (1929), where she employs a feminist rhetoric of affect and emotion. Woolf’s particular contribution to the essay includes a new kind of literary history that focuses on women, gender, and politics. Hers is a uniquely feminine and feminist voice created through a visceral and sensual rhetoric that addresses the body’s response to experience and exploits emotions in order to persuade her readers.

Abstract The Research Collaboratory for Structural Bioinformatics Protein Data Bank (RSCB PDB) provides a wide range of digital data regarding biology and biomedicine. This huge internet resource involves a wide range of important biological data, obtained from experiments around the globe by different scientists. The Worldwide Protein Data Bank (wwPDB) represents a brilliant collection of 3D structure data associated with important and vital biomolecules including nucleic acids (RNAs and DNAs) and proteins. Moreover, this database accumulates knowledge regarding function and evolution of biomacromolecules which supports different disciplines such as biotechnology. 3D structure, functional characteristics and phylogenetic properties of biomacromolecules give a deep understanding of the biomolecules’ characteristics. An important advantage of the wwPDB database is the data updating time, which is done every week. This updating process helps users to have the newest data and information for their projects. The data and information in wwPDB can be a great support to have an accurate imagination and illustrations of the biomacromolecules in biotechnology. As demonstrated by the SARS-CoV-2 pandemic, rapidly reliable and accessible biological data for microbiology, immunology, vaccinology, and drug development are critical to address many healthcare-related challenges that are facing humanity. The aim of this paper is to introduce the readers to wwPDB, and to highlight the importance of this database in biotechnology, with the expectation that the number of scientists interested in the utilization of Protein Data Bank’s resources will increase substantially in the coming years.

This paper analyses Gottemann's spatial model in relation to his complex biography which took place during some of the great historical changes of the 20th century. In particular, it relates the concept of Megalopolis to his theoretical wrigtings in political geography. The development of the latter ones could not be fully understood without referece to his "transhumance" between the two sides of the Atlantic from 1941 to 1961.

AbstractDuring the 20th century, there have been numerous scholarly attempts in studying, analyzing and even to some extent, criticizing the issues pertaining to the contacts, impacts and relations between the Muslim world and the West. However, when dealing with these issues, the geography should not be limited to the Muslim world and the West, Europe in particular, but it should cover both Europe and Asia taken together where the earliest civilizations took place and by the 7th century, Islamic civilization flourished in the center of domain civilizations. With a wider and more positive look, the four articles by the academicians, (namely Danial M. Yosuf, Ali Çaksu, Anke Iman Bouzenita and Mesut Idriz), selected to be featured in this edition will contribute not only to this field of study but also avoid or remove the barriers and concentrate on the bridges between the Islamic world and the Eurasia. All the articles are original works and published for the first time in this volume The focus of this special edition is on the paradoxes between the Islamic and Eurasian worlds.

Висвітлюється процес зародження жанру «вуличної» (батярської) пісні як важливого елементу міської музичної субкультури в контексті принципових історично обумовлених змін у житті полікультурної громади Галичини кінця XIX – першої третини ХХ ст. Розглянуто виняткову за вагомістю у формуванні традицій популярної пісенності Галичини творчість січового стрілецтва та плеяди митців, що несли національну та регіональнупатріотичну символіку, виконували функції своєрідного мистецького протиставлення чужорідним впливам окупаційних режимів. Виявлено, що репертуарна традиція міської пісенної субкультури Галичини, як і творчість митців УСС та її фольклоризовані форми, будучи усталеною нормою широкого народного вжитку для західноукраїнських територій, поступово проектується на подальші процеси жанротворення та має значний впливна тенденції розвитку популярно-естрадної пісенності регіону.Ключові слова: естрадна пісня, патріотична пісня, міська пісенна субкультура, пісні Січових стрільців, регіональна пісенна традиція. The article highlights the process of formation of the genre of street («batiarskiy») song as an important element of the urban musical subculture in the context of fundamental historical changes in the life of the multicultural community of Galicia region at the end of the 19th – the first third of the 20th century. The exceptional importance of the creativity of Sich Riflemen and a whole galaxy of artists, who carried national and regional patriotic symbolism, ,performed the functions of a peculiar artistic opposition to alien influences of the occupation regime in forming of the traditions of the popular song of Galicia is considered in a separate perspective. It is revealed that the repertoire tradition of the urban song subculture of Galicia, as well as the creativity of the Ukrainian Sich Riflemen’s artists and its folklorized forms, being the established norm of widespread popular use for the western Ukrainian territories, is ,,gradually projected on further processes of genre formation and certainly has a significant influence on the trends of popular development.Key words: variety song, patriotic song, urban song subculture, the songs of Sich Riflemen, regional song ,tradition.

AbstractThis article presents a microhistory of an early 20th-century Tunisian intellectual, Salih Suwaysi, within the context of cross-regional (Maghrib–Mashriq) literary and intellectual trends. Analyzing Suwaysi's use of the conventional literary genre of maqāmāt illustrates his deep understanding of the problems caused by France's occupation of Tunisia and highlights the significance of historical and contemporary urban space for the author. Revitalized during the nahḍa period, maqāmāt were employed by writers to address issues and problems facing contemporary society, in contrast to some of the earlier maqāmāt that focused on language and language structure more than on narrative content. Suwaysi followed his eastern Mediterranean, especially Egyptian, contemporaries in turning to this genre to convey his critical commentaries on social, religious, and political life under the French Protectorate in Tunisia.

Creative works of amateur authors are significant in the reflection of ethnic culture in the provincial periodicals. In the publications of “Kurskie eparhialinie vedomosti” (“Kursk diocesan Gazette”) the fact of existence and dynamic development of the clergy subculture in the Kursk province was fixed. The study of peculiarities concerning the concept of “a Small Motherland” in the poetic experience of provincial authors will allow to reconstruct the important parts of the cultural space in pre-1917 Russian province and also to promote the deep understanding of provinces’ role in literary process at the end of the XIX — the beginning of the XX century.
