Biogeochemistry of Estuaries offers a comprehensive and interdisciplinary approach to understanding biogeochemical cycling in estuaries. Designed as a text for intermediate to advanced students, this book utilizes numerous illustrations and an extensive literature base to impart the current state-of-the-art knowledge in this field. While many of the existing books in estuarine science are comprised of edited volumes, typically focused on highly specific topics in estuaries,Biogeochemistry of Estuaries provides, for the first time, a unique foundation in the areas of geomorphology, geochemistry, biochemistry, aqueous chemistry, and ecology, while making strong linkages (trhoughout the text) to ecosystem-based processes in estuarine sciences. Estuaries, located at the interface between land and the coastal ocean are dynamic, highly productive systems that, in many cases, have been historically associated with development of many of the great centers of early human civilization. Consequentially, these systems have and continue to be highly impacted by anthropogenic inputs. This timely book takes the foundational basis of elemental cycling in estuarine and applies it to estuarine management issues. Biogeochemistry of Estuaries will be welcomed by estuarine/marine scientists, ecologists, biogeochemists, and environmentalists around the world.

At present, the problem of establishing disability is a point at issue in Russia. Despite the fact that medical criteria for disability are being developed very actively, high-quality methods for assessing social hallmarks are still lacking. Since disability is a phenomenon inherent in any society, each state forms a social and economic policy for people with disabilities in accordance with its level of development, priorities and opportunities. We have proposed a three-stage model, which includes a system for the consistent solution of the main tasks aimed at studying the causes and consequences of the problems encountered today in the social protection of citizens with health problems. The article shows why the existing approaches to the determination of disability and rehabilitation programs do not correspond to the current state of Russian society and why a decrease in the rate of persons recognized as disabled for the first time does not indicate an improvement in the health of the population. The authors proposed a number of measures with a view to correcting the situation according to the results of the study.

Background: Frontotemporal Dementia (FTD) is a neurodegenerative disorder which asymmetrically affects the frontotemporal lobe, characterized by behavioural abnormalities, language impairment, and deficits of executive functions. Genetic studies identified mutations causing the disease, namely Microtubule Associated Protein Tau (MAPT), Granulin (GRN) and chromosome 9 open reading frame 72 (C9orf72) mutations, which contributed to elucidate the molecular pathways involved in brain depositions of either Tau or TAR DNA-binding protein 43 (TDP43) inclusions. However, in the majority of sporadic FTD patients, the mechanisms triggering Tau or TDP43 protein deposition are still to be uncovered. Objective: We aimed to present an extensive evaluation of literature data on immune homeostasis in FTD, in order to provide potentially evidence-based approaches for a disease still orphan of any treatment. Methods: A structured search of bibliographic databases from peer-reviewed literature was pursued focusing on autoimmunity in the brain and FTD. Results: One-hundred-fourteen papers were included in this review. The majority of studies (32) were represented by extensive literature revision on immunity, central nervous system (CNS) and autoimmunity; neuroimaging papers (11) in autoimmune diseases were evaluated, and immunomodulatory approaches (25) were revised. Six papers were found specifically related to FTD and autoimmune hypothesis, the other papers referring to current state of art on FTD. Conclusion: Overall this review contribute to expand the knowledge of a possible immune hypothesis in FTD, suggesting therapeutic perspectives in autoimmune related neurodegeneration, to reduce or revert the disease.

AbstractContinuous multi-channel monitoring of biopotential signals is vital in understanding the body as a whole, facilitating accurate models and predictions in neural research. The current state of the art in wireless technologies for untethered biopotential recordings rely on radiative electromagnetic (EM) fields. In such transmissions, only a small fraction of this energy is received since the EM fields are widely radiated resulting in lossy inefficient systems. Using the body as a communication medium (similar to a ’wire’) allows for the containment of the energy within the body, yielding order(s) of magnitude lower energy than radiative EM communication. In this work, we introduce Animal Body Communication (ABC), which utilizes the concept of using the body as a medium into the domain of untethered animal biopotential recording. This work, for the first time, develops the theory and models for animal body communication circuitry and channel loss. Using this theoretical model, a sub-inch$$^3$$ 3 [1″ × 1″ × 0.4″], custom-designed sensor node is built using off the shelf components which is capable of sensing and transmitting biopotential signals, through the body of the rat at significantly lower powers compared to traditional wireless transmissions. In-vivo experimental analysis proves that ABC successfully transmits acquired electrocardiogram (EKG) signals through the body with correlation $$>99\%$$ > 99 % when compared to traditional wireless communication modalities, with a 50$$\times$$ × reduction in power consumption.

Abstract A standardized terminology for the anatomy of pectoral- and dorsal-fin spines in the order Siluriformes is proposed based on an extensive literature review and direct examination of representatives of the order. The adult anatomy of the spines is described in detail. Terminology of various spine parts are reviewed and standardized, each term provided with a synonymic list organizing previous usage. Most of the structures treated have been recorded and named in the literature, but some are herein named for the first time. A quantitative approach is proposed for orienting decisions on name usage, aiming at minimizing differences between the terminology proposed and the vast amount of pre-existing literature, herein called the cost function. It is expected that this system will aid efforts in organizing the chaotic anatomical nomenclature of the appendicular skeleton in Siluriformes, and provide a solid basis for advances in comparative anatomy and nomenclature. The proposed terminology system has potential application on a number of fields that utilize information from catfish spines, ranging from taxonomy to phylogenetic systematics to paleontology and archaeology.

Cultural studies as a humanities researcher takes the place of an expert. The relevance of this topic is due to the lack of development of the issues of “culture-based studies” in Ukrainian culturology. There is a lack of translated into French or Ukrainian languages of French sources published since 1975. French culturological science, which developed after 1975, is almost not represented in Ukrainian culturology. The present stage of the development of French historiography, which lies at the heart of cultural history, and cultural studies, is associated with increased attention to social knowledge. This stage is characterized by the deployment of a “critical turn”, which proceeds from the following principles: the interdisciplinary approach, the significance of cultural expertise, the severity of publications and the multiplicity of their forms, multidisciplinarity. The “critical turn” affects the following spheres of knowledge: la Culturologie, les Études culturelles, les Sciences de la Culture. The article substantiates the relevance of the use of the concept of “culture-based studies” to the definition of processes that are unfolding within the framework of French humanities and are associated exclusively with the theoretical formations in the context of the social sciences. The purpose of the article is to outline a map of culture-based studies in the field of French humanitaristics. The methodology of the article is based on the application of interdisciplinary and multidisciplinary approaches to research in the field of culturology. Also, methodological developments in the field of “critical turn” and the achievements of the sociological circle and the interdisciplinary discussion club “Eranos” were applied. The scientific novelty of the article is to substantiate the appropriateness of the use of the concept of “culture-based studies” on the definition of processes that are unfolding within the framework of French humanitaristics and relate exclusively to theoretical formations in the context of social sciences. This concept to the field of Ukrainian culturology is introduced for the first time. Also, for the first time, the place and forms of culturology in French humanities were clarified. Conclusions. Working with a source base and methodology is one of the points that are compulsory on the way to the solution of the tasks, the main of which is the formation of the body of fundamental works for French history (including the history of culture) and historiography of the period since 1975 year to the present day. On the basis of this building, there is the prospect of building an alternative national cultural history project addressed to the vector of the French historiographical, historical-anthropological and cultural-related issues in the field of social knowledge. The article presents the arguments why it is appropriate to use the concept of “culture-based studies” in the context of conducting research in relation to French humanitaristics, in particular, the modern period of its development.

This paper analyzes the current state of landscaping in Ishim. The data on the qualitative and quantitative characteristics of woody plants have been obtained for the first time; the assessment of trees and shrubs state is based on the analysis of the vitality index. A database of green plants within 21 objects in Ishim was created and analyzed. The paper also contains data on the species diversity of trees and shrubs in Ishim. It turned out that the objects under study have trees and shrubs placed in special dividing strips, linearly, in rows or in small compact groups, less often they are planted singly. The species composition is represented by 47 species from 28 genera, 16 families and 2 divisions. The biomorphological structure is represented by trees (25, or 53% of species) and shrubs (22, or 47% of species). The total composition of tree and shrub plantations, determined by the number of trunks (bushes) and the percentage of woody plants, is 2854; the composition of the preserved ones is 2 815 (99%) pieces; the ones assigned for removal are 39 (1%) pcs. The vitality index shows that among 85% of the studied objects of the town at the time of the survey were healthy, among 10% of the objects they were qualified as damaged, among 5% of them were severely damaged. Based on the results of examining crowns and trunks of woody plants, signs of diseases and pests, a plan of measures for the treatment, restoration and preservation of woody plants was drawn up and recommendations were given for caring, sanitary felling and removal of single specimens.

The purpose of the article is to analyze support of the independent processes, using any tool of information technology (IT) outside of the information system (IS) in the enterprise environment. The useful tool of IT could be the software (SW) ATOM, an ontology-driven web based application. Changes in IS are very expensive, complicated and risky, but it should be suggested solution omitted. The extensive literature review of the current state of the topic is added. The chosen process is innovation; the life cycle of innovation is explained: suggestion of innovation, demand for the solution of innovation, the final solution of innovation, and project for implementation of innovation. The methodology of an ontology preparation for the SW application includes design scheme of classes and associations between classes, preparation table of assignment characteristics to classes, and implementation of an ontology design in SW ATOM. The real possibility to support independent processes outside of IS using an ontology-driven application was experimentally verified and confirmed, and the result of research work could be used for any process outside of IS. Limits of the proposed solution consist of only experimental laboratory verification. For the practical use, it should be necessary first to prepare a prototype for the corporation IS in an enterprise environment.

Sanitary and microbiological researches of a coastal surface water of the southern part of Lake Baikal (from the Listvyanka to the Tanghui) were conducted in June, 2017. Total number of bacteria varied over a wide range – from 0.93 million сells/ml up to 2:05 million сells/ml, with an average 1.41 ± 0.3 million сells/ml. Biomass of bacteria varied from 11.05 to 305.00 mg С/m3, with an average of 123.34 mg С/m3. Coastal waters of the southern site of Lake Baikal mainly had a beta-meso-saprobic status in June, 2017. The total microbial number was determined with the use of the test systems for the first time. The values of the total microbial number were less than 1 000 COU/ml and varied from 9 to 412 COU/ml. Innovative test systems Petrifilm are of great interest for rapid assessments of the sanitary and microbiological status of reservoirs directly in the field conditions.

Pindar's Odes, blending beauty of poetic form and profundity of thought, are one of the wonders of Ancient Greece. Composed in the first instance to commemorate athletics victories, they fan out like a peacock's tail to illuminate with brilliant subtlety and imagination the human condition in general, and how our moments of heroic achievement are inevitably tempered by our mortal frailties. This edition aims to make for the first time a selection of these wonderful, but complex, poems accessible and enjoyable not only to scholars and advanced students but especially to sixth-form students and non-Classicists (including anyone interested in Pindar's influence on English poetry). While particular attention is paid to elucidating Pindar's cryptic chains of thoughts and to explaining the significance of the myths in the odes, much greater help than usual in this series is given with translating the Greek. The selection, which contains Pindar's most famous poem (Olympian 1) and two particularly charming mythical stories (in Pythian 9 and Nemean 3), illustrates Pindar's range and variety by including odes commemorating victors at each of the four major games. The book presents Greek text with translation, commentary and notes.
