Perovskite Type

Starting with a history of the fundamental science, currently, the perovskite structures exemplify the extensive manifestation of crystal chemistry which is associated with the smart synthesis techniques to develop a new type of material. The perovskite structures exhibit the most efficient single accomplished ceramic host. Perovskite structured nanomaterials had originated from CaTiO3. They are made up by the assembling of distinct materialistic components and follow the general configuration ABX3. Perovskite type metal oxide nanomaterial shows a wide range of ferroelectric, piezoelectric, and pyroelectric properties along with numerous optoelectrical effects. They get the facility to the various advanced technical applications due to the excellency in their properties. The photocatalytic activity may be one of the plausible and impulsive applications of that very special type of materials. Most elements in the periodic table are able to take part in designing the perovskite-type materials. Perovskite structured nanoparticles (NPs) are applying rapidly for global development because of their higher responsiveness and degree of function, large surface area, size-dependent properties etc and unfold the new possibilities in the field of nanotechnology.

The Relationship

A post-anthropocentric epistemological assemblage becomes indispensable in the investigation of the ecology of the Romanian novel. We examine the interactive relationship of various dynamic systems, such as 1) the evolution of the Romanian novel, 2) the modes of representation of the environment, and 3) the social-political history of the autochthonous space. Using a wide range of methodological perspectives, this paper also examines the relationship between literature and the Earth sciences, thus envisioning a new type of literary history where the Romanian novel should be thought as existing within hyper-objects, such as the climate, agriculture, wilderness, pollution, biosphere, cultural politics, capitalism, or geology. The article finally addresses the issue of zoopoetics both as an object of study in the MDRR digital archive (1845-1947) and as a reading strategy, thus, favoring the relationship between animality and narrativity.

Adults Who Stutter

Purpose This study explored group experiences and individual differences in the behaviors, thoughts, and feelings perceived by adults who stutter. Respondents' goals when speaking and prior participation in self-help/support groups were used to predict individual differences in reported behaviors, thoughts, and feelings. Method In this study, 502 adults who stutter completed a survey examining their behaviors, thoughts, and feelings in and around moments of stuttering. Data were analyzed to determine distributions of group and individual experiences. Results Speakers reported experiencing a wide range of both overt behaviors (e.g., repetitions) and covert behaviors (e.g., remaining silent, choosing not to speak). Having the goal of not stuttering when speaking was significantly associated with more covert behaviors and more negative cognitive and affective states, whereas a history of self-help/support group participation was significantly associated with a decreased probability of these behaviors and states. Conclusion Data from this survey suggest that participating in self-help/support groups and having a goal of communicating freely (as opposed to trying not to stutter) are associated with less negative life outcomes due to stuttering. Results further indicate that the behaviors, thoughts, and experiences most commonly reported by speakers may not be those that are most readily observed by listeners.

This introduction surveys the rise of the history of emotions as a field and the role of the arts in such developments. Reflecting on the foundational role of the arts in the early emotion-oriented histories of Johan Huizinga and Jacob Burkhardt, as well as the concerns about methodological impressionism that have sometimes arisen in response to such studies, the introduction considers how intensive engagements with the arts can open up new insights into past emotions while still being historically and theoretically rigorous. Drawing on a wide range of emotionally charged art works from different times and places—including the novels of Carson McCullers and Harriet Beecher-Stowe, the private poetry of neo-Confucian Chinese civil servants, the photojournalism of twentieth-century war correspondents, and music from Igor Stravinsky to the Beatles—the introduction proposes five ways in which art in all its forms contributes to emotional life and consequently to emotional histories: first, by incubating deep emotional experiences that contribute to formations of identity; second, by acting as a place for the expression of private or deviant emotions; third, by functioning as a barometer of wider cultural and attitudinal change; fourth, by serving as an engine of momentous historical change; and fifth, by working as a tool for emotional connection across communities, both within specific time periods but also across them. The introduction finishes by outlining how the special issue's five articles and review section address each of these categories, while also illustrating new methodological possibilities for the field.

Early English

Literature written in England between about 500 and 1100 CE attests to a wide range of traditions, although it is clear that Christian sources were the most influential. Biblical apocrypha feature prominently across this corpus of literature, as early English authors clearly relied on a range of extra-biblical texts and traditions related to works under the umbrella of what have been called “Old Testament Pseudepigrapha” and “New Testament/Christian Apocrypha." While scholars of pseudepigrapha and apocrypha have long trained their eyes upon literature from the first few centuries of early Judaism and early Christianity, the medieval period has much to offer. This article presents a survey of significant developments and key threads in the history of scholarship on apocrypha in early medieval England. My purpose is not to offer a comprehensive bibliography, but to highlight major studies that have focused on the transmission of specific apocrypha, contributed to knowledge about medieval uses of apocrypha, and shaped the field from the nineteenth century up to the present. Bringing together major publications on the subject presents a striking picture of the state of the field as well as future directions.

Dmitrii Mendeleev (1834–1907) is a name we recognize, but perhaps only as the creator of the periodic table of elements. Generally, little else has been known about him. This book is an authoritative biography of Mendeleev that draws a multifaceted portrait of his life for the first time. As the book reveals, Mendeleev was not only a luminary in the history of science, he was also an astonishingly wide-ranging political and cultural figure. From his attack on Spiritualism to his failed voyage to the Arctic and his near-mythical hot-air balloon trip, this is the story of an extraordinary maverick. The ideals that shaped his work outside science also led Mendeleev to order the elements and, eventually, to engineer one of the most fascinating scientific developments of the nineteenth century. This book is a classic work that tells the story of one of the world's most important minds.

<p>Although solvent-ligand interactions play a major role in nanocrystal synthesis, dispersion formulation and assembly, there is currently no direct method to study this. Here we examine the broadening of <sup>1</sup>H NMR resonances associated with bound ligands, and turn this poorly understood descriptor into a tool to assess solvent-ligand interactions. We show that the line broadening has both a homogeneous and a heterogeneous component. The former is nanocrystal-size dependent and the latter results from solvent-ligand interactions. Our model is supported by experimental and theoretical evidence that correlates broad NMR lines with poor ligand solvation. This correlation is found across a wide range of solvents, extending from water to hexane, for both hydrophobic and hydrophilic ligand types, and for a multitude of oxide, sulfide and selenide nanocrystals. Our findings thus put forward NMR line shape analysis as an indispensable tool to form, investigate and manipulate nanocolloids.</p>

The purpose of the article is to study the dynamics of electronic dictionaries development abroad and in Ukraine using methods of analysis of scientific sources, comparison, generalization and systematization. Electronic dictionaries have been found to be a relatively new phenomenon in the lexicographic market, evolving from machine-readable dictionaries, exact copies of paper editions to complex digital lexicographic systems with a powerful arsenal of functions over the decades. The stages of development of autonomous and online dictionaries are described. Electronic dictionaries due to the advanced search capabilities, speed, simplicity, ease of use, accessibility and compactness have gained popularity among a wide range of users. Today they are used in many spheres of human activity – scientific, educational, professional, everyday communication. However, the analysis of the current level of development of Ukrainian electronic resources indicates a shortage of electronic dictionaries both common and terminological vocabulary. The lack of electronic dictionaries is due to a number of objective problems, both practical and theoretical, that is why research in the field of domestic computer lexicography is a promising area of further research.

At the present stage, Kazakh musical culture is heterogeneous. It represents traditions coexisting at the same time and interacting with each other: Kazakh ethnic and newly established composer school (tradition). Examining changes in cultural landscapes of the 20th century I reveal the peculiarities of interaction and dialogue between two kinds of culture: ethnic and global (endogenous and exogenous). The procedures include the complex study of the history of Kazakh culture in the 20th century, stylistic analysis of traditional and composer’s music, semiotic approach to intercultural interaction, as far as a comparative analysis of oral and written music of 19th and 20th centuries. On one hand, dramatic changes in the structure of music culture were caused by external objective reasons: new industrial and postindustrial civilization phases (urbanization and information technologies); intensification of interaction with western (mainly Russian) cultures, etc. On the other hand, some changes were inspired by inner factors: diverse development of local song and kui (dombyra piece) traditions; Soviet cultural policy. As a result new type (or layer) of national culture – Kazakh composers’ music – appeared. It was connected with the formation of a national style based on transcriptions and borrowing. Traditional music was influenced by new social institutions (philharmonic halls, theatres, radio, conservatoire) that caused changes in the creative process (decrease of oral transmission, lack of traditional social context) as well as in the style (virtuoso performance, new genres of songs).
