“Estate topos” is usually considered in the works of authors who had estates or for a long time were living in estates of their relatives and friends. Significantly less attention is paid to the characterization of the “estate topos” in the texts of the authors, who, due to class restrictions, were not the owners of the estates and their frequent guests. In the literature of the Russian Silver Age, these are primarily the poets of the “peasant concord” group: N. Klyuev, S. Ese nin, A. Shiryaevets, S. Klychkov and oth- ers. For them, the most important and often the earliest in time of development of the source of knowledge about the Russian estate was Russian literature. The poets got an idea of estate complexes from personal experience. Elements of these complexes become symbols, each of which has a semantic filling formed over a long period. Revolutionary events of 1917–1921 lead to the rapid death of the estate world. If Klyuev in the early post-revolutionary years welcomed this process, then for Shiryaevets the Russian estate is inseparable from peasant life, Esenin is characterized by the transfer of elements of landlord complexes to the space of the peasant estate, in the heritage of Klychkov, like some other authors, an important role is played by a garden connected not only with the landowner estate, but also with peasant life, with the Garden of Eden.

Although cyclo[18]carbon has been theoretically and experimentally investigated since long time ago, only very recently it was prepared and directly observed by means of STM/AFM in condensed phase (Kaiser et al., <i>Science</i>, <b>365</b>, 1299 (2019)). The unique ring structure and dual 18-center π delocalization feature bring a variety of unusual characteristics and properties to the cyclo[18]carbon, which are quite worth to be explored. In this work, we present an extremely comprehensive and detailed investigation on almost all aspects of the cyclo[18]carbon, including (1) Geometric characteristics (2) Bonding nature (3) Electron delocalization and aromaticity (4) Intermolecular interaction (5) Reactivity (6) Electronic excitation and UV/Vis spectrum (7) Molecular vibration and IR/Raman spectrum (8) Molecular dynamics (9) Response to external field (10) Electron ionization, affinity and accompanied process (11) Various molecular properties. We believe that our full characterization of the cyclo[18]carbon will greatly deepen researchers' understanding of this system, and thereby help them to utilize it in practice and design its various valuable derivatives.

Acid-sensing ion channels (ASICs) are proton-gated Na+ channels. Being almost ubiquitously present in neurons of the vertebrate nervous system, their precise function remained obscure for a long time. Various animal toxins that bind to ASICs with high affinity and specificity have been tremendously helpful in uncovering the role of ASICs. We now know that they contribute to synaptic transmission at excitatory synapses as well as to sensing metabolic acidosis and nociception. Moreover, detailed characterization of mouse models uncovered an unanticipated role of ASICs in disorders of the nervous system like stroke, multiple sclerosis, and pathological pain. This review provides an overview on the expression, structure, and pharmacology of ASICs plus a summary of what is known and what is still unknown about their physiological functions and their roles in diseases.

Computer systems for primates to listen to audio have been researched for a long time. However, there is a lack of investigations into what kind of sounds primates would prefer to listen to, how to quantify their preference, and how audio systems and methods can be designed in an animal-focused manner. One pressing question is, if given the choice to control an audio system, would or could primates use such a system. In this study, we design an audio enrichment prototype and method for white-faced sakis that allows them to listen to different sounds in their regular zoo habitat while automatically logging their interactions. Focusing on animal-centred design, this prototype was built from low fidelity testing of different forms within the sakis’ enclosure and gathering requirements from those who care for and view the animal. This process of designing in a participatory manner with the sakis resulted in an interactive system that was shown to be viable, non-invasive, highly interactive, and easy to use in a zoo habitat. Recordings of the sakis’ interactions demonstrated that the sakis triggered traffic audio more than silence, rain sounds, zen, and electronic music. The data and method also highlight the benefit of a longitudinal study within the animals’ own environment to mitigate against the novelty effect and the day-to-day varying rhythm of the animals and the zoo environment. This study builds on animal-centred methods and design paradigms to allow the monitoring of the animals’ behaviours in zoo environments, demonstrating that useful data can be yielded from primate-controlled devices. For the Animal-Computer Interaction community, this is the first audio enrichment system used in zoo contexts within the animals own environment over a long period of time that gives the primate control over their interactions and records this automatically.

Experimental procedures used for the study of reinforcement to concrete bond have been hampered for a long time by inconsistencies and large differences in the obtained behavior, such as bond strength and mode of failure, depending on the specimen form and setup used in the test. Bond is controlled by the mechanics of the interface between reinforcement and concrete, and is sensitive to the influences of extraneous factors, several of which underlie, but are not accounted for, in conventional pullout test setups. To understand and illustrate the importance of specimen form and testing arrangement, a series of computational simulations are used in the present work on eight distinct variants of conventional bar pullout test setups that are used routinely in experimental literature for the characterization of bond-slip laws. The resulting bond strength increase generated by unaccounted confining stress fields that arise around the bar because of the boundary conditions of the test setup is used to classify the tests with respect to their relevance with the intended use of the results. Of the pullout setups examined, the direct tension pullout test produced the most conservative bond strength results, completely eliminating the contributions from eccentricity and passive confinement.

Opening Paragraph

Opening ParagraphSeen in the widest perspective, 1787 is only one date among the uncounted tens, perhaps hundreds, of thousands of years during which the present Sierra Leone has been inhabited. Archaeologists have done disappointingly little work there. But it is clear from their findings (and by implication from findings in the rest of forest-belt West Africa) that people have lived there a very long time. Though traditional historiography always tends to present the peoples of Sierra Leone as immigrants from somewhere else, the language pattern suggests continuous occupation over a very long period. As Paul Hair (1967) has shown, there has been a striking linguistic continuity in coastal West Africa since the fifteenth century. Nor is there evidence to suggest that before that period stability and continuity were not the norm.

On the eighth day, chemical analysis began. Adam, recovering after cooperating with God in creating Eve, felt the first pangs of hunger. Looking around, he spied a pile of stones left over after creation of some nearby mountains. He rejected a soft friable sandstone and chose a hard granite rock, took careful aim at a rabbit, and hit it squarely between the eyes. This was the basis for the first real meal in the Garden of Eden. A day or two later, Eue took a whiff of the rabbit carcass, thought for a moment, then fed it to the dog.Thus, the first chemical analytical instruments were Adam's eye and hand and Eve's nose. These, plus taste, sufficed by themselves for a long time thereafter but, eventually, refinements were necessary.

Insight Into

The article gives an insight into criminological problems of bullying in school phenomena. Although the term “bullying” is a modern word, such behaviour has been known for a long time. Bullying is a manifestation of violent behaviour, which threatens the victim's health and safety. The aim of this article is to describe and analyse bullying as a form of expression of violence, showing the criminological aspects of this phenomenon. To achieve the aim of the article the following tasks are defined: to provide the theoretical and practical framework of the research phenomenon, to study and evaluate certain elements of the criminological characterization of the bullying: the description of a victim and a perpetrator, the evaluation of factors and directions of prevention. Theoretical analysis methods such as deconstruction, descriptive and complex analysis, and empirical research methods – document analysis, comparison and compilation were employed in this study.

This article is based on interviews with fifteen children, whose parents have addiction problems. Purpose: To contribute to in-depth understanding of children's situation when parents have ceased abusing drugs or alcohol. Method: An explorative interview study with childhood sociology and symbolic interactionism as theoretical framework. Outcome: The end of the abuse gives children space to feel how they feel, to reflect on the impact of the addiction on their health and personality, and to try changing themselves and their lives. Their need for processing may last for a long time. It can take time and be difficult to build up the relationship with the parent. Children can still feel care responsibility but also distrust and worry about relapses. However, teenagers can see opportunities to move on with their own life. If the abuse ends only for one of two parents with addiction problems, children are still affected by addiction. Conclusion: Children's need for processing in relation to the parents can both be time consuming and last for a long period of time, regardless of if the child lives with the parent or not. Children may need help for their own part but also in relation to the parent. Professionals should be encouraged to work with a family perspective, regardless of organizational divisions and if parents and children live together or not. This requires structures, procedures and resources for collaboration across organizational boundaries.
