Structural, grammatical and linguocultural aspects of the meteorolexeme "halun" in the Mongolian languages
Authors: Barinova Bairta Valer'evna , Mushaev Vladimir Naranovich
Published: April 2024

The article analyzes the meteorological vocabulary in the Mongolian languages, which characterizes hot weather. The linguistic means of expressing hot weather in the worldview of the Mongolian peoples can be represented as integral and consistent natural phenomena that are systematically used by traditional speakers in direct, figurative, comparative, evaluative and metaphorical meanings. The object of the study is nominative units (words, phrases, phraseological units) in Mongolian languages that characterize hot weather. Special attention is paid to the analysis of the compatibility of the "halun" meteorological system. The bearers of a nomadic civilization are directly dependent on the natural and climatic features that determined the state of nomadic management, orientation and location of a person in nature and society. The relations of nature, man and the animal world, reflected in the ethnic consciousness of native speakers, had their own systemically categorical forms of expression in linguistic pictures of the world. For the Mongolian peoples, in addition to universal verbal forms of expression of these relations, the whole variety of linguistic and cultural approaches was used to express figuratively comparative and evaluative aesthetic means of language. This article uses a descriptive method, a comparative method, a method of linguistic and cultural analysis of lexical units. In the linguistic picture of the world of a traditional native speaker, the halun lexeme "heat, depending on the temperature regime, can denote different degrees of heat manifestation: from ordinary heat to incredible, exhausting heat, affecting the physical condition of a person. As examples, the author uses Mongolian lexicographic sources, texts of artistic and folklore works, in which lexemes denoting hot weather were analyzed from meteorological vocabulary. Meteorological vocabulary characterizing hot weather is considered in the article from the point of view of their composition, semantics, morphological-syntactic and lexico-semantic method of education. The peculiarity of artistic and folklore texts makes it possible to consider a specific lexeme in its various combinations, which makes it possible to fully reveal the features of the semantic structure of the word. In this aspect, meteorological names characterizing hot weather in the Kalmyk language are considered and systematized for the first time.
Representation of the lyrical "I" in the poetry by A. Podgornova
Authors: Muromtseva Alena Olegovna
Published: April 2024

The multidimensional study of women's poetry is one of the promising strategies of modern Russian literary criticism, which allows us to reveal not only the tools of women's writing, but also the female mentality, feminine identity, and the peculiarities of reflection by a female author of the natural and social world. Among the female authors, a special place is occupied by the Erzya poet Alina Podgornova, whose works trace postmodern trends. The subject of the research in the article is the means of representing the lyrical "I" in the poet's poems. The purpose of the work is to analyze a number of the author's works, to determine the system of images through which the lyrical "I" is represented, to trace their conditioning by the postmodern worldview of the poetess. The material was composed of poems from the collections "Except rhymes", "Stranded" ("Thought"). The methodological basis of the work is determined by the structural and semantic analysis of the lyrical text, through which the structural components of the poetic image, its semantic organization, and symbolic semantics are described. The scientific novelty of the study is determined by the fact that, in the stated aspect, A. Podgornova's lyrics are for the first time considered and introduced into the context of Russian literary criticism. The article argues that the emotional and psychological state of the lyrical heroine A. Podgornova is due to the author's worldview and axiological concept, his perception of the world as chaos, moral apocalypse. The poetess's worldview is filled with negative social manifestations that destroy the spiritual and moral essence of a person, leveling universal values. The conclusions and provisions presented in the article expand the understanding of the state and development of modern Mordovian literature.

Authors: Shcherbakova Milena Viktorovna , Komlev Nikita Pavlovich
Published: April 2024

The subject of the study is the media linguistic features of the text of a tabletop role-playing game (TRPG). The purpose of the work is to identify the essential features of the media text and answer the question: can media accompaniment of a tabletop role–playing game be considered a media text? Despite the sufficient elaboration of the topic of media communications on the Internet, the research material is a little-studied phenomenon. The research material is transcripts of sessions of the board RPG "Dungeons & Dragons" from fragments of the TV show "Critical Role" on streaming platforms. The study examined the emergence and development of the media text concept, noting a significant expansion of this term semantics in the context of media globalization. Further, the typological properties of the media text as an object of linguistic media research were systematized and the text of the TRPG was analyzed for compliance with existing criteria. The article used descriptive and comparative methods; a statistical method to assess the popularity of the TRPG. When working with the transcript of the game, Python programming methods were implemented: to increase clarity and create a correct text transcription. As a result, conclusions were drawn about the presence of such media linguistic features in the media accompaniment of TRPG as collective authorship, hypertextuality, interactivity and etc., which constituted the scientific novelty of the study. Comparative analysis by criteria allowed us to trace qualitative changes in the typology of media texts. In addition, the expediency of expanding the terminological apparatus of media linguistics was emphasized, which correlates with the study of transmedia narration. The results of the observations can be applied to improve the text-generation that accompanies the gameplay, and can also be used to conduct similar studies based on the speech material of TRPGs.
Images of Traditional Chinese Medicine Doctors in Chinese Literature
Authors: CHEN KUO
Published: April 2024

Since ancient times, doctors have usually played the image of rescuers who save lives. As a symbol-rich image, "doctor" often enters the scope of writers' creativity and becomes a typical creative theme. This paper explores the image of Traditional Chinese Medicine (TCM) doctors in literature. The purpose of the study is to understand how TCM practitioners are portrayed and represented in literature, to analyze their social and cultural influence and their impact on people's perceptions and attitudes towards TCM. The relevance of this article is that it can help people to better understand the position and image of TCM in different historical periods and cultural environments, as well as its relationship with society, culture and people's lives. The subject of this paper is the image of TCM doctors in literary works of a certain period, region or cultural context such as ancient works, modern literary works and works of specific writers. By analyzing the images in different works, the diversity of such images of TCM physicians such as wise doctors and mysterious healers can be demonstrated. This paper uses methods of literary analysis, including close reading of the text, character analysis, plot and theme study. The text is also studied in the context of historical and cultural context to understand the views and attitudes of the society of the time towards TCM and doctors. The scientific novelty of studying the image of traditional Chinese medicine in Chinese literature gives us an interdisciplinary perspective that integrates literature with medicine and cultural studies and offers new ways to deeply understand TCM culture and human perception of health. The results of the study indicate the diversity of TCM physicians' images in the literature. In addition, the findings may reflect different understandings and evaluations of TCM in different periods and cultural contexts.
Analysis of temporal and spatial systems in chinese linguoculture (on russian language background).
Authors: Qiu Taorui
Published: April 2024

The present article is dedicated to the concepts of time and space as a fragment of the Russian and Chinese linguistic worldviews. Notions of time are fundamental to any culture and people's worldview, hence in this study, we attempt to "unify" the aspects of Chinese and Russian time and space that we have identified through research. Our research object, as a fragment of the Russian linguistic worldview, is connected with notions of time and space. The subject of our investigation is the linguistic means in which Russian speakers' notions of time are expressed, considered against the backdrop of the Chinese language in lexical, semantic, and grammatical aspects.The aim of the study is to identify and describe the main features of the representation of time in Chinese and Russian languages, as well as to highlight the main differences in the representation of time and space in the Chinese and Russian linguistic worldviews. Structural-semantic, linguacultural, and comparative analysis methods are employed to analyze the conceptual models of time in these two languages. The scientific novelty of this article lies in the attempt to use a spatial model to describe the concept of time in order to identify possible temporal dimensions in language, as well as in attempting to interpret and generalize the notions of time from the perspective of the cognitive perception of Chinese language speakers. The theoretical significance of this article lies in the endeavor to specify the cognitive perception of language speakers through the analysis of historical and cultural origins of time models, as well as in generalizing some regularities of time expression in modern languages. Studying the fundamental concept of time and space models contributes to the further development of cognitive models, translation, teaching Russian and Chinese as foreign languages etc.
Sociocultural and linguodiscursive characteristics of irony
Authors: Gornostaeva Anna Alekseevna
Published: April 2024

The article is a review of existing scientific views on irony as a phenomenon at the junction of several disciplines. Definitions of this phenomenon are presented from the point of view of philosophical, aesthetic, anthropological, literary, linguistic approach. The views on irony as a category of the comic, a worldview category, as a way of perceiving and comprehending reality are listed. The author points out that in the process of communication, irony is a kind of barrier to dividing participants into "ironic" and their "victims", that is, those who are able to interpret irony and the "uninitiated". Discursive irony is considered as a product of interaction, cooperation between the author and the addressee, as a result of which an ironic effect may arise (if the ironic utterance is correctly interpreted) or not (in the case of a communicative failure).  Various interpretations of the concept of "irony" are considered in comparison, arguments are given justifying the author's agreement / disagreement with existing formulations. The focus of the article is on irony, an effect that arises as a result of interaction between interlocutors: the ironic speaker and the recipient who perceives and interprets irony. The author's contribution to the development of the theory of discourse is expressed in the analysis of irony in English and Russian linguistic cultures. The article highlights the main socio-cultural and linguodiscursive characteristics of irony. The conclusion is made about the importance of irony in communication, about its role in the verbal and emotional intelligence of the participants of the discourse. The novelty of the research lies in the fact that in the proposed work irony is considered as an integral characteristic of modern English and Russian discourse, which ensures that the speaker achieves the fulfillment of a communicative intention. The main result of the work is the postulate about the ethnostilistic labeling of irony, which opens up wide prospects for studying the features of irony in national discourses. The data presented in the article can be used for the further development of ethnostilistics, linguistic pragmatics, and the theory of intercultural communication.
Rethinking the (Un)just Transition: A Review of the Impact of Neoliberal Approaches to Energy Governance in South Africa
Authors: Lekunze Angwe Rachel
Published: April 2024

South Africa has demonstrated a firm commitment to a just transition from coal to renewable energy sources by outlining a roadmap for the decommissioning of its coal-fired power stations and procuring clean energy. Ideally, this is a laudable response to climate change and a pathway to a sustainable future. However, the just transition is not inherently just because of the underlying neoliberal policies that underpin it, and which are, to a large degree, not in South Africa’s best interests. The purported just transition has unintended results, such as undermining South Africa’s energy sovereignty, perpetuating existing global power imbalances, aggravating energy poverty, and leading to many economic and social injustices. This paper uses doctrinal legal research to explore the influence of neoliberal policies in South Africa’s just transition towards renewable energy. It argues that a truly Just Energy Transition must be grounded in South Africa’s best interests and should not sacrifice the country’s energy sovereignty for a perceived greater good at a time when giant economies in the West, which are responsible for the bulk of activities which contribute to climate change, are revamping their coal-fired power stations and buying South Africa’s coal for their own heating, lighting, and industry. To achieve this, the paper examines the duplicity arising from what may be perceived as an embrace of neoliberal policies in fighting climate change by phasing out existing energy sources at a time when economic activity in the country is retreating due to the lack of a consistent and reliable energy supply. As such, the paper makes a case for an energy-sovereign South Africa that prioritises domestic control over energy resources, promotes renewable energy deployment that is socially just and equitable, and empowers communities to shape their energy futures. It argues that for South Africa to attain energy sovereignty, it must look into its own resources and revisit the neoliberal aspects of its law and policy that compromise its ability to fight energy poverty.
A Critical and Comparative Analysis of the Regulation of the Office of the Chairman in Contemporary South African Companies
Authors: Cassim Rehana
Published: April 2024

The role of chairman of the board of directors of a contemporary company has evolved from procedural and ceremonial to complex and demanding. This article examines the appointment, tenure, functions, and liabilities of this position, as regulated by the Companies Act 71 of 2008, the JSE Limited Listings Requirements, and the King IV Report on Corporate Governance for South Africa 2016. The aim is to ascertain whether the guidance provided to chairmen on their appointment, tenure, functions, and liabilities is clear and adequate to guide them on what is expected of them in contemporary companies. Company law in the United Kingdom and Australia is compared because this area of law has been extensively developed in these jurisdictions and may offer guidance on the regulation of the office of the chairman of South African companies. The article contends that the guidance provided to a chairman by South African legal instruments is neither clear nor adequate. It identifies several shortcomings in the regulation of the chairman and makes recommendations to enhance the South African statutory and corporate governance provisions regulating the chairman.

В статье представлены экспериментальные данные по определению расхода воды через горизонтальные трубки круглого сечения, имеющие различный диаметр. Определена зависимость объемного расхода от перепада давления, показано, что основными параметрами, определяющими характер течения жидкостей в горизонтальных трубках являлись радиус трубки и динамическая вязкость жидкости. Рассмотрено течение дистиллированной воды в трубках с диаметрами 0.95·10-3 м, 1.6·10-3 м и 2.0·10-3 м при избыточном давлении от 0,266 кПа до 4 кПа. Показано, что зависимость объемного расхода от избыточного давления остается линейной при 0.95·10-3 м во всем рассмотренном диапазоне давлений. Увеличение радиуса трубки повышает вероятность возникновения флуктуаций скорости и появления радиальной составляющей скорости, т.е. возникновения элементов турбулентной струк­туры. В связи с этим при диаметрах трубки 1.6·10-3 м и 2.0·10-3 м установлено отклонение режима течения воды от ламинарного характера при значениях давления более 1,3 кПа и 1 кПа, соответственно. Зависимость объемного расхода от давления для 40% водного раствора CaCl2, трансформаторного, трансмиссионного и моторного масел с коэффициентами динамической вязкости от 2·10-3 Па·с до 182·10-3 Па·с остается линейной вплоть до диаметров трубок 5÷6·10-3 м. Результаты экспериментов изображены в виде номограммы зависимости коэффициента  от радиуса трубки при различных значениях коэффициента вязкости μ, анализ которой позволяет предсказать, каков будет характер течения исследуемой жидкости при заданных значениях радиуса трубки и коэффициента динамической вязкости.

Published: April 2024

Diblock oligomeric peptide-polymer amphiphiles (PPAs) are biohybrid materials that offer versatile functionality by integrating the sequence-dependent properties of peptides with the synthetic versatility of polymers. Despite their potential as biocompatible materials, the rational design of PPAs for assembly into multi-chain nanoparticles remains challenging due to the complex intra- and intermolecular interactions emanating from the polymer and peptide segments. To systematically explore the impact of monomer architecture on nanoparticle assembly, PPAs were synthesized with a random coil peptide (XTEN2) and oligomeric alkyl acrylates with unique side chains: ethyl, tert-butyl, n-butyl, and cyclohexyl. Experimental characterization using electron and atomic force microscopies demonstrated that tail hydrophobicity impacted accessible morphologies. Moreover, characterization of different assembly protocols (i.e., bath sonication and thermal annealing) revealed that certain tail architectures provide access to kinetically trapped assemblies. All-atom molecular dynamics simulations of micelle structure formation unveiled key interactions and differences in hydration states, dictating PPA assembly behavior. These findings highlight the complexity of PPA assembly dynamics and serve as valuable benchmarks to guide the design of PPAs for a variety of applications including catalysis, mineralization, targeted sequestration, antimicrobial activity, and cargo transportation

Published: April 2024

Underutilized wastewaters containing dilute levels of reactive nitrogen (Nr) can help rebalance the nitrogen cycle. This study describes electrodialysis and nitrate reduction (EDNR), a reactive electrochemical separation architecture that combines catalysis and separations to remediate nitrate and ammonium-polluted wastewaters while recovering ammonia. By engineering operating parameters (e.g., background electrolyte, applied potential, electrolyte flow rate), we achieved near-complete recovery and conversion of Nr in both simulated and real wastewaters. EDNR process demonstrated long-term robustness and recovered >100 mM ammonium fertilizer solution from 8.2 mM Nr-containing agricultural runoff. EDNR is the first reported process to our knowledge that remediates dilute real wastewater and recovers ammonia from multiple Nr pollutants, with an energy consumption (245 MJ/kg NH3-N in simulated wastewater, 920 MJ/kg NH3-N in agricultural runoff) on par with the state-of-the-art. Demonstrated first at proof-of-concept and engineered to technology readiness level (TRL) 5, EDNR shows great promise for distributed wastewater treatment and sustainable ammonia manufacturing.
Enhancement of interlayer exchange coupling via intercalation in 2D magnetic bilayers: Towards high Curie temperature
Authors: Mishra Suman , Park In Kee , Javaid Saqib , Shin Seung Hwan , Lee Geunsik
Published: April 2024

Two-dimensional magnetic materials are considered as promising candidates for developing next-generation spintronic devices by providing the possibility of scaling down to nanometers. However, a low Curie temperature is a crucial problem for practical applications, being intimately related to weak interlayer exchange coupling. Here, by using density functional theory calculations, we show that interlayer exchange coupling can be enhanced by intercalating 3d transition metals (Sc to Zn) into a bilayer of CrI3 and NiI2. It is found that intercalated Ni and Cr atoms exhibit strong antiferromagnetic coupling with the CrI3 and NiI2 host layers, respectively. This enhances the ferromagnetic interlayer exchange coupling between the host layers by many folds compared to pristine CrI3 and NiI2 bilayer. Moreover, both intercalated compounds show the out-of-plane magnetic anisotropy with half metallic nature, which makes them ideal candidates for spintronics application. Thereby our work provides a rational approach to raise the Curie temperature of non-metallic two-dimensional magnets by intercalation.
Micellar (Photo-)Catalysis driven by IR-Active Semiconductor Surfactants
Authors: Polarz Sebastian , Jaschke Marian , Siroky Stephan , Kalies Stefan , Weber Nils , Heisterkamp Alexander
Published: April 2024

In micellar catalysis, one uses aggregates formed by surfactants as nanoreactors for performing chemical reactions. A special class of tailor-made surfactants containing catalytically active sites opens new perspectives in micellar catalysis. Little is known about the combination of such surfactants with photocatalysis. Molecular semiconductors are presented, which simultaneously have amphiphilic properties and are made of a hydrophilic fullerenol head group attached to dye molecules as the hydrophobic entity. The first generation of those surfactants produces reactive oxygen species (ROS) when exposed to light in the UV/Vis range. The concept of the current paper is that one can drive the photocatalytic process also using low-energy photons in the near-infrared region. For this purpose, NIR-active dye molecules were selected and attached to the fullerenol head. It is shown that a fullerenol - aminostilbene compound representing the second generation of semiconductor surfactants fulfills all requirements. It forms aggregates in water that are catalytically active. Moreover, two-photon experiments with lamda = 780 nm were performed, indicating successful ROS production and, thus, photocatalytic activity.
TS-tools: Rapid and Automated Localization of Transition States based on a Textual Reaction SMILES Input
Authors: Stuyver Thijs
Published: April 2024

Here, TS-tools is presented, a Python package facilitating the automated localization of transition states (TS) based on a textual reaction SMILES input. TS searches can either be performed at xTB or DFT level of theory, with the former yielding guesses at marginal computational cost, and the latter directly yielding accurate structures at greater expense. On a benchmarking dataset of mono- and bimolecular reactions, TS-tools reaches an excellent success rate of 95% already at xTB level of theory. For tri- and multimolecular reaction pathways – which are typically not benchmarked when developing new automated TS search approaches, yet are relevant for various types of reactivity, cf. solvent- and autocatalysis and enzymatic reactivity – TS-tools retains its ability to identify TS geometries, though a DFT treatment becomes essential in many cases. Throughout the presented applications, a particular emphasis is placed on solvation-induced mechanistic changes, another issue that received limited attention in the automated TS search literature so far.

Published: April 2024

The immobilization of molecular electrocatalysts on conductive electrodes is an appealing strategy for enhancing their overall activity relative to analogous molecular compounds. In this study we report on the interfacial electrochemistry of self-assembled 2D nanosheets of graphene nanoribbons (GNR-2DNS) and analogs containing a Rh-based hydrogen evolution reaction (HER) catalyst (RhGNR-2DNS) immobilized on conductive electrodes. Proton-coupled electron transfer (PCET) taking place at N-centers of the nanoribbons was utilized as an indirect reporter of the interfacial electric fields experienced by the monolayer nanosheet located within the electric double layer. The experimental Pourbaix diagrams were compared with a theoretical model which derives the experimental Pourbaix slopes as a function of parameter f, a fraction of the interfacial potential drop experienced by the redox-active group. Interestingly, our study revealed that GNR- 2DNS was strongly coupled to glassy carbon electrodes (f = 1), while RhGNR-2DNS was not (f = 0.15). We further investigated the HER mechanism by RhGNR-2DNS using electrochemical and X-ray absorption spectroelectrochemical methods and compared it to the homogeneous molecular model compounds. RhGNR-2DNS was found to be an active HER electrocatalyst over a broader set of aqueous pH conditions than its molecular analogs. We find that the improved HER performance in the immobilized catalyst arises due to two factors. First, redox-active bipyrimidine- based ligands were shown to dramatically alter the activity of Rh sites by increasing the electron density at the active Rh center and providing RhGNR-2DNS the improved catalysis. Second, the catalyst immobilization was found to prevent catalyst aggregation that was found to occur for the molecular analog in the basic pH. Overall, this study provides valuable insights into the mechanistic by which catalyst immobilization can affect the overall electrocatalytic performance.
Enhancing the control of boron epoxy cross-ply laminated composite plates through intelligent implementation of PZT sensor and actuator
Authors: K. Dileep Kumar , M. Lova Kumari
Published: April 2024

Piezoelectric materials find diverse applications in structural engineering, particularly in fields like condition monitoring, smart control, and testing. The captivating interplay between their mechanical and electrical properties has garnered significant attention, showcasing immense potential for practical utility. Notably, these materials boast costeffectiveness, lightweight characteristics, compact size, exceptional dynamic capabilities, swift responsiveness, enduring stability, and remarkable energy conversion efficiency. In our research initiative, we delve into a study concentrated on the symmetric surface attachment of two piezoelectric patches or actuators onto composite laminate plates. The goal is to induce a bending effect in the laminate by applying equal-magnitude electric voltages with opposite polarities to these symmetrically positioned piezoelectric actuators. The determination of the bending moment involves the application of principles related to elasticity and piezoelectricity. To scrutinize the displacement and natural frequency of the composite plate influenced by this bending moment, we utilize plate theory and derive analytical solutions. Furthermore, these piezoelectric patches, affixed to the composite laminate plate's surface, double as vibration actuators. We subject the plate to loads to investigate its vibration response in a simply supported rectangular configuration. This excitation is achieved by applying time-harmonic voltages to the piezoelectric patches. Throughout our study, we compute analytical solutions for both deflection and vibration amplitude, presenting numerical results that depict the static deflection and vibration amplitude of the plate. Additionally, a parametric study is conducted to elucidate the influence of piezoelectric actuator size and placement on cross-ply composite laminate plates.

Authors: Chen Dongmei
Published: April 2024

Objective: To analyze the value of ultrasound imaging combined with serum indicators in evaluating the invasiveness of papillary thyroid cancer (PTC). Methods: One hundred and fifty patients with papillary thyroid cancer admitted to our hospital from September 2019 to December 2022 were selected. Pathological tissue testing was performed on all patients. According to the size, shape, boundary, internal echo, and characteristics such as microcalcification, the patients were divided into the PTC metastasis group (n = 55) and the PTC group (n = 95). The detection rate of ultrasound imaging combined with serum indicators and the invasiveness of PTC were observed and analyzed. Results: The detection rate of ultrasound imaging combined with serum indicators in both groups was significantly better than that of ultrasound imaging and serum indicators (P < 0.05). The detection rate of ultrasound imaging combined with serum indicators was compared between the groups. The removal rate of the PTC metastasis group was significantly better than that of the PTC group (P < 0.05). The levels of thyroid-stimulating hormone (TSH), thyroglobulin (Tg), thyroglobulin antibodies (TgAb), and thyroid autoantibodies (TPOAb) in the PTC group were lower than those of the PTC metastasis group (P < 0.05). Conclusion: Ultrasound imaging combined with serum indicators like TSH, Tg, TgAb, and TPOAb has important clinical significance in evaluating the invasiveness of PTC.
Averaging of a normal system of ordinary differential equations of high frequency with a multipoint boundary value problem on a semi-axis
Authors: Levenshtam V. B.
Published: April 2024

A multipoint boundary value problem for a nonlinear normal system of ordinary differential equations with a rapidly time-oscillating right-hand side is considered on a positive time semi-axis. For this problem, which depends on a large parameter (high oscillation frequency), a limiting (averaged) multipoint boundary value problem is constructed and a limiting transition in the Hölder space of bounded vector functions defined on the considered semi-axis is justified. Thus, for normal systems of differential equations in the case of a multipoint boundary value problem, the Krylov-Bogolyubov averaging method on the semi-axis is justified.
Family model and family-gender roles in the assessments of modern youth
Authors: Kuznetsov V. O. , Saveleva Zh. S.
Published: April 2024

Modern trends in changing the marriage and family attitudes of  modern youth are characterized by the transformation of gender roles. Based on  a questionnaire survey of modern youth, social attitudes of young people were  obtained regarding the gender distribution of roles in the sphere of decision-making, financial security of the family, parenthood, organization of everyday  life and a favorable climate in the family, as well as the assessment of these areas  in the parental family. Data indicate an egalitarianization of the family model,  but in relation to the sphere of family provision, this trend is less pronounced.  Young people more often name love as the reasons for starting a family, followed  by socio-psychological comfort and having children.

Fundamento: A qualidade de vida e o nível de autocuidado de indivíduos hipertensos pode ser influenciada por diversos fatores. O conhecimento destes fatores no município de Arapiraca-AL pode auxiliar na implementação de políticas públicas direcionadas.

Objetivo: Descrever a qualidade de vida e o nível de autocuidado dos pacientes com Hipertensão Arterial (HA) do município de Arapiraca, nos anos de 2019-2020. 

Métodos: Estudo observacional transversal envolvendo 100 indivíduos com diagnóstico clínico de HA. A avaliação foi composta por uma ficha de avaliação de dados clínicos e pessoais e três questionários: Qualidade de vida em hipertensão arterial (MINICHAL-BRASIL), Perfil de autocuidado da hipertensão (PAC- HTN) e Questionário de percepção de hábitos saudáveis (QPHAS). 

Resultados: A média de idade dos indivíduos avaliados foi de 64±11,52 anos, 74% do sexo feminino e 67% eram sedentários. A qualidade de vida dos entrevistados foi considerada satisfatória. A adesão ao tratamento não medicamentoso foi baixa, principalmente no que se refere a prática de atividade física, alimentação e monitorização da PA em casa.

Conclusão: Os participantes apresentaram boa qualidade de vida, porém com baixa adesão à terapia não medicamentosa, interferindo no autocuidado desses pacientes.
Ecology of an alluvial-seepage lake: El Campillo (SE Madrid, Spain)
Authors: Álvarez Cobelas Miguel
Published: April 2024

The gravel-pit lake number of Madrid County is high arising from the dramatically-growing building industry in the last decades, which has needed huge quantities of materials coming from nearby alluvial plains, giving rise to newly-formed lakes. Some of those lakes are close to streams and experience the indirect influence of riverine and alluvial environments, as is the case for Campillo lake, which is located in the lower Jarama catchment. This contribution reviews its available ecological knowledge, also supplying information previously unknown. In addition to the aforementioned water inputs, with the accompanying nutrient income, the occurrence of a Northern gypsum cliff is important because 1st it supplies runoff sulphate to the lake and 2nd summer dynamics in anoxic lake layers is associated with its partial reduction to sulphide and the behaviour of iron and manganese. This low transparency, stratifying lake is dominated by a stable phytoplankton in the long-term where the cyanobacterium Planktothrix agardhii prevails. Its status is hypertrophic, albeit long-term analyses suggest that the phosphorus concentration is declining, a fact that could arise from its recent partial abatement in the Jarama river. Finally, more updated and widened knowledge on lake biodiversity is necessary and some remedial actions to improve its environmental quality are suggested. El número de lagunas de gravera existentes en la Comunidad de Madrid es elevado, como resultado de la enorme actividad constructora en las últimas décadas, la cual ha necesitado gran cantidad de materiales de construcción extraídos de ellas. Algunas se encuentran muy próxi¬mas a los ríos y la influencia indirecta tanto del medio fluvial como del acuífero aluvial sobre las mismas es muy patente, como en el caso de la laguna del Campillo, situada en el tramo bajo del río Jarama. Este artículo revisa los conocimientos existentes sobre dicho ecosistema, aña¬diendo mucha información inédita. Además de la citada alimentación hídrica, que lleva aparejada la entrada de nutrientes al lago, resulta muy importante la presencia de un acantilado yesífero septentrional que aporta sulfato a la laguna por escorrentía y cuya dinámica estival en las zonas anóxicas de la laguna se asocia con su reducción parcial a sulfuros y con la de hierro y manga¬neso. El ecosistema, de escasa transparencia y térmicamente estratificado durante buena parte del año, está dominado por un fitoplancton estable a largo plazo donde reina la cianobacteria Planktothrix agardhii, y es hipertrófico, si bien los datos sugieren que las concentraciones de fósfo¬ro han disminuido desde hace unos años, lo cual podría deberse al reciente descenso de dichas concentraciones en el río Jarama. En cuanto a los organismos, el conocimiento de la biodiver¬sidad lacustre necesita ampliarse y actualizarse. Este artículo propone también algunas medidas para mejorar el ecosistema.
