Published: December 2023

Abstract Objective To define cut-off points for the values of the Maximum Handgrip Strength (MGS) test in long-lived elderly people. Method Cross-sectional study with a sample of long-lived elderly people, octogenarians and nonagenarians, healthy and functionally independent (robust group) and frail (fragile group). The MHS test was performed in triplicate, with the highest value obtained being considered. Sensitivity, specificity and cut-off values were calculated using the Receiver Operating Characteristic Curve (ROC). The Brazilian cut-off points and those of the European Consensus on Sarcopenia were used for the comparison study. Results 121 elderly people were evaluated, with a mean age of 84.5±5.3 years, 65 (53.7%) female, 46 (38%) from the frail group and 75 (62%) from the robust group. Cut-off points for MHS of 27 kgf for men and 19 kgf for women were found. Sensitivity and specificity values for men’s cutoffs were 94.44 and 65.79, respectively. For woman, they were 85.71 and 67.57. Based on these cutoff points, 23 (38.3%) individuals from the robust group were classified as having competitive strength, and therefore with probable sarcopenia, while according to the Brazilian and European cutoff points, the number is 35 (44.3%) and 14 (33.3%). Conclusion The study defined cut-off points for the oldest-old population and showed that the cut-off points defined so far for the Brazilian elderly population were not adequate for the oldest-old.

A new record of green spore in Lomaria (Blechnaceae, Polypodiospida)
Authors: Gasper André Luís de , Machado Giesta Maria Olmedo , Karkow Mariana Hartmann , Funez Luís Adriano
Published: December 2023

Abstract Fern spores play a vital role in dispersal. The unique features of spores, such as size, thickness, and ornamentation can aid in taxonomic decisions and division of groups. Moreover, certain species of ferns possess green spores containing chlorophyll, an uncommon feature that can reinforce the evidence of relatedness within a specific group. Lomaria spannagelii is a Neotropical species endemic to Brazil, and, even though green spores have been reported in its sister species, Lomaria nuda and Lomaria discolor, the presence of these spores has not yet been investigated in L. spannagelii. In this study, we investigated the morphology of L. spannagelii spores and sporangia, and, additionally, we determined the chromosome count of the species. Our results showed that the analyzed species has green spores, a characteristic shared with L. nuda and L. discolor, and has 2n = 64 chromosomes. This discovery provides new insights into this fern genus and emphasizes the importance of spore color and chromosome count in systematic and evolutionary studies of ferns.

Published: December 2023

Abstract Seasonality is one of the main characteristics of a tropical dry forest that affects the structure of ecological communities. In this context, we evaluated the seasonal diversity of ferns and insects in the tropical dry forest of Morelos, Mexico, to determine whether a relationship exists between the presence of each of these two groups. Hill’s numbers indicated differences in the diversity of both groups according to season. In the rainy season, we recorded the highest diversity of ferns, with 6,471 individuals. In contrast, in the dry season, we recorded only 293 individuals. Regarding the insects, we collected 723 individuals in the rainy season and 171 individuals in the dry season. The order Orthoptera was the most abundant (50%). The best-represented functional group according to feeding guild was that of chewing herbivores. Correlation analysis revealed a positive relationship between insect and fern abundances since, for both groups, the minimum abundance was presented in the dry season and the maximum abundance in the rainy season. We recorded 12 orders of insects associated with eight ferns in the rainy season. Seasonal studies that consider different biological groups are necessary to understand how changes in resource availability shape temporal patterns of species diversity.

Published: December 2023

Abstract Ferns and lycophytes are plants often overlooked in most floristic inventories, leading to considerable gaps in the knowledge of their diversity and geographic distribution. To address this issue, we conducted a study aimed at reducing these gaps for the restingas of Santa Catarina, south Brazil. This involved conducting a series of field works in strategic sites within the municipality of Laguna, representing all three main restingas phytophysiognomies (herbaceous/subshrubby, shrubby, and arboreal), across different abiotic conditions and conservation degrees. Two species of lycophytes (one family) and 31 ferns (14 families) were recorded in the restingas of Laguna, almost three-quarters of the diversity reported for the restingas of the state of Santa Catarina. Besides, 11 of these species are mentioned here for the first time for Santa Catarina restingas. These numbers were obtained through extensive field surveys, but considering the area of restinga remnants, some of which are still relatively unexplored, it is plausible that the diversity of ferns and lycophytes in Laguna may be even greater. These findings reinforce the need to carry out floristic surveys aimed at ferns and lycophytes in the different phytophysiognomies of the restinga, because only with an increase of sampling effort, considering the environmental heterogeneity, it will be possible to better estimate the diversity of these and other plant groups. This study also provides important data for the management and conservation of the restingas, which are among the ecosystems historically most impacted by human activities.

Authors: Reis Atiles , Oliveira Maria Izabel Ramalho de , Bial Marcela , Mynssen Claudine Massi
Published: December 2023

Abstract The Jardim Botânico do Rio de Janeiro (JBRJ) has an arboretum with 58 hectares of green space, including thematic collections. The ex situ collection of ferns and lycophytes is in two greenhouses: Mestre Valentim and the Shade Greenhouse of Horto Florestal. Although the JBRJ Arboretum is a cultivated area, it is adjacent to Parque Nacional da Tijuca (PNT), which is a fragment of the Atlantic Forest that may influence the flora in the garden. Specimens were collected and identified between 2020 and 2023 from all areas of the JBRJ, including the greenhouses. There are 101 species of ferns and lycophytes that belong to 47 genera and 24 families. Pteridaceae (21%) and Polypodiaceae (19%) are the most species-rich families. The collections in the Mestre Valentim and Shade greenhouses comprise 70 species, 35 genera, and 20 families. Five cultivated species are at risk of extinction: Adiantum mynsseniae, Dicksonia sellowiana, Anemia blechnoides, Doryopteris rediviva, and Pteris congesta. Most of the species inventoried in the JBRJ collection are native to Brazilian ecosystems (70%), including 10 endemic species. A list of species found in the JBRJ, with information about the location, distribution range, vouchers and type of occurrence (collection or spontaneous), is provided.
Morphogenesis of the gametophyte of Physematium montevidensis (Woodsiaceae)
Authors: Martinenco María Luz , Arana Marcelo Daniel , Luna María Luján
Published: December 2023

Abstract In vitro spore culture and gametophyte characteristics may contribute understanding the life cycle in different fern taxa and also to systematic and taxonomic studies. The family Woodsiaceae contains two genera: Physematium and Woodsia. Physematium montevidensis is the only species recognized for South America, and up to now, no information has been recorded on the gametophytic phase. The aim of this work is to study the development pattern, the morphology and sexual expression of the gametophyte of Physematium montevidensis to provide information about its reproductive biology. The germination pattern was of the Vittaria-type and the gametophyte development of the Aspidium-type. Gametangia appeared 30-40 days after spore germination. Both, cordiform bisexual and spatulate-elongated male gametophytes developed in the cultures. The sporophytes emerged near 3 months after spore sowing. The gametophyte development of Physematium montevidensis and its morphological features are broadly similar to those registered in other taxa of Woodsiaceae.
Climatic triggers of the phenophases of Elaphoglossum macrophyllum in Southern Brazil
Authors: Graeff Vanessa , Müller Andressa , Junges Fernando , Bauer Danielle , Oliveira Marciel Teixeira de , Schmitt Jairo Lizandro
Published: December 2023

Abstract Although ferns have a prominent floristic position with their richness center in Atlantic Forest in Brazil, the effect of climate on their phenophases is still poorly known. This group shows different phenological patterns due to the great latitudinal extent, the strong climatic seasonality of this forest, and the leaf dimorphism found in some species. In this scenario, we evaluated the phenological events of Elaphoglossum macrophyllum and related them to climatic factors. Fertility, leaf renewal, and leaf senescence in E. macrophyllum were analyzed based on the monthly survey of 152 plants growing for two years in the subtropical Atlantic Forest, Brazil. The three analyzed phenophases showed the same intra-annual pattern regarding continuity, regularity, and seasonality along the two years, revealing a phenological pattern for the specie. The generalized additive models for location, scale, and shape (GAMLSS) indicated that photoperiod was the most important trigger for fertility and leaf renewal. Temperature, as an important phenology modulator, was related to leaf renewal and senescence. Our data indicate that E. macrophyllum, an endangered species in southern Brazil, withstands the consequences of seasonal climatic variations without the individual mortality, total leaf shedding, or fertility loss.

Published: December 2023

Abstract Dicksonia sellowiana (Dicksoniaceae) is a tree fern characteristic of the mixed ombrophilous forests of southern Brazil in the Atlantic Forest. Due to its extensive use in the past for making garden pots, this species is at risk of extinction. The objective of this study was to evaluate the phytochemical composition of D. sellowiana leaves and their structures and correlate it with their antioxidant potential. Measurements of moisture content, extraction yield, preliminary phytochemical analysis, chemometric analysis by 1H NMR PCA, UPLC-PDA-MS analysis, total polyphenol content, and antioxidant activity were conducted on the leaves and their structures. The phytochemical composition confirmed the presence of polyphenols, including tannins and flavonoids (derived from kaempferol), with higher concentrations in the pinna and lower in the rachis. The pinnule exhibits high diversity and concentration of phytochemical compounds, which justify its antioxidant activity due to the presence of polyphenols. In conclusion, this study highlights that the pinnae and leaves of D. sellowiana exhibit a similar and more diverse phytochemical composition compared to the other evaluated structures, showing higher concentrations of polyphenols and antioxidant activity. The results reinforce the preservation of the endangered species and its potential as a resource for pharmacological and nutritional phytochemical compounds.

Ethnographic studies in Information Science: bibliometric analysis in the Web of Science database
Authors: Bufrem Leilah Santiago , Freitas Juliana Lazzarotto , Araújo Paula Carina de
Published: December 2023

Abstract Ethnography has been recognized as a valuable methodological resource in Information Science research. In this study, we describe Information Science scientific articles on ethnography — and others that use ethnographic methodologies — indexed in the Web of Science database. Bibliometric research found 803 articles indexed in the database’s Core Collection, covering the period from 1979 to 2020. The analysis of these articles shows that 2016 concentrates the highest number of publications (65), and points to Michael D. Myers as the most productive and most cited author in WoS. Among the 15 most productive institutions with research on this topic, the University of Toronto stands out with slightly more than half of the total number of articles. Moreover, the Health Sciences stand out with articles focused on management and information systems. This study thus contributes to understanding the difficulties of research in this field, which result from the transformations and obstacles common to the various ethnographic research approaches and its emerging nature in Information Science.

Published: December 2023

Abstract Society is undergoing unprecedented transformations caused by big economic, political, technological, social and mostly demographic changes. In this line, the role and weight of older adults turns more important due to the modifications such transformation will bring about in their characteristics, needs, expectations and goals as regards their personal, economic, political, technological and social aspects. This situation has given rise to the concept of Silver Economy, which broadly speaking represents that part of the economy related to the demographic change caused by aging population, including all those economic activities, products and services intended to meet the needs of older adults. Its being a growing field of knowledge makes it complex to identify the driving forces and agents that boost its development and therefore to promote and consolidate this new concept. In accordance with this opportunity, this piece of research maps the main research themes available in literature, making use of SciMAT-based smart bibliometric tools and techniques. In addition to other actions, this research makes it possible to identify the main themes, who the relevant agents are, the pioneering countries in this field, and the more productive organizations and sources. To this end, the Scopus database has been used as main source, bearing in mind that it concentrates 281 publications from 1979 to 2022 related to older adults and their role in economic, political, technological and social development, which has resulted a detailed frame of reference on Silver Economy.

Published: December 2023

Gold nanoparticles (AuNPs) have gained significance due to their size and shape. The current study aimed to prepare AuNPs by using green - plasma jet and calculate the cellular toxicity of those manufactured nanomaterials. Aqueous gold tetrachloride salts (HAuCl4·4H2O) and essential oil of lemon peels in different ratios (0:10, 1:9, 2:8, and 3:7) were used to produce AuNPs. The synthesized green-prepared gold was characterized by ultraviolet-visible (UV-vis), X-ray diffraction (XRD), and field emission scanning electron microscopy (FESEM). UV-vis spectrum showed the highest absorption at 540 nm, and the patterns of XRD at the ratio (2:8) showed four peaks occurred at peaks at 2θ = 38.1, 44.3, 64.5, and 77.98. FESEM study illustrated that the AuNPs particle sizes range between (38-76 nm). The cell toxicity results have shown the effectiveness of the green synthesized AuNPs on the breast cancer (AMJ13) cell line. The breast cancer (AMJ13) cell line is found to be more inhibited when the concentration of AuNPs reaches 100%. According to the findings, creating nanoparticle materials for the therapy of breast cancer cells using green-cold plasma is a potential technique.

Changing the working conditions of the mineral wool cupola during the transition from an open type to a closed one
Authors: Matyukhin V. I. , Matyukhina A. V.
Published: December 2023

The widespread use in the industry of mine furnaces of the wagon type requires the organization of management of their gasdynamic and thermal regime. In the mode of operation of a cupola with an open grate, its thermal mode is characterized mainly by the peripheral movement of gases with a significant difference in the ratio of heat capacities of gas flows and materials. The use of forced removal of exhaust gases from the shaft furnace contributes to an earlier transition from a peripheral to a predominantly central movement mechanism. By increasing the degree of rarefaction on the grate to 0,71‒0,73 bar, it is possible to increase the level of melt temperature, temperature pressure and air blast flow, exhaust gas temperature while improving the conditions of heat exchange between gases and heated materials. This process will be accompanied by a continuous decrease in the productivity of the unit with an improvement in the stability of the melting process. A further increase in the level of rarefaction on the grate contributes to the gradual transition of the mechanism of movement of gases from the peripheral to the central one with a deterioration in the parameters of the wagon melting.
Cancelling of Announced Elections: Possible Reasons, Conditions, Procedure, and Legal Consequences
Authors: Podshivalov Vladimir
Published: December 2023

The article reasons the possibility and the necessity to make provisions in the Russian electoral legislation for a new legal institution which can be denominated as “cancelling of announced elections” or “early discontinuance of electoral campaign”. The terminological issues for denomination of the legal institution are discussed. The paper shows various circumstances to decide the cancelling of the announced elections (changes in the territorial organization of the public authorities; changes on the legal regulation; execution of the court decision aimed to restore the someone’s rights; mistake made in announcing of the elections, and others). The article discusses which of the mentioned circumstances should be referred to in the electoral legislation and which way the reference should be done. The proposed mechanism allows to take into account the cases when continuation of electoral campaign does not have any meaning and (or) results in violation of the citizens’ rights to elect or to be elected. The author believes the decision to cancel the announced elections, including the case of cancelling the decision to announce the elections, must be exercised exclusively by the court. Steps to be taken by electoral commissions and candidates to implement the decision to cancel the announced elections are analyzed. The practice of the Constitutional Court of the Russian Federation and the Supreme Court of the Russian Federation is examined to make recommendations for the law-making authorities to achieve the proper balance of the public and private interests in the field. The author proposes the optimal juridical technique to amend the Russian electoral and procedural legislation and makes specific law-making suggestions.
Subject of Private International Law: Formation of Doctrinal Ideas
Authors: Aslanyan Natalya
Published: December 2023

The formation of doctrinal ideas about the subject of private international law has been going on for more than a century, but this process cannot be called either completed or successful. It is incomplete since until now the understanding of the subject of the science of private international law is debatable and is replete with a wide variety of interpretations. It is unsuccessful, because the prevailing understanding of the subject of the science of private international law does not correspond to the scientific canons. The article shows that in the pre-revolutionary jurisprudence the scientific views both on private international law in an objective sense (as the set of conflict rules) and on the subject of science of private international law were characterized by certainty and reflected correlation between a fragment of reality (object) to be studied and the field of jurisprudence studying the given fragment of reality. In the post-revolutionary period of the development of Russian science, pre-revolutionary ideas about private international law as a conflict of laws were rejected due to ideological and political reasons, which led to a significant change in views on the subject of the science of private international law. In private international law, in an objective sense, both conflict of laws and substantive and procedural norms began to appear, as a result the subject of the science of private international law has been transformed into a theoretical construct that does not have clear boundaries. This approach was consolidated in the Soviet period and today forms the basis of the dominant doctrine. The author justifies the conclusion that the doctrine does not correspond to the scientific requirements to the differentiation of scientific knowledge, since the postulated provisions contradict scientific standards defining the subject of science, and the current state of affairs impedes building a general theory of private international law.
On the Issue of Applying the Civil Law to the Property Relations of Spouses by Analogy
Authors: Tolstikova Olga , Kostyunina Olga
Published: December 2023

The relationship between the norms of civil and family law in determining the legal status of the property of spouses within the framework of contractual relations is considered. It is noted that due to the novelty of the institution of contractual property relations for Russia, the peculiarities of the Russian citizens’ mentality, expressed in the predominance of the emotional component of marital relations over the rationality of regulating property relations between spouses, the question of the need to establish norms and eliminate gaps, conflicts when choosing a contractual regime of spouses’ relations in Russian law is important. It is argued that the ambiguity in determining the independence of the subject of family law regulation gives rise to contradictions in the implementation of the norms governing contractual relations of family and civil legislation since property disputes between spouses are regulated by family law, which initially follows from the normative prescriptions of Articles 2 and 35 of the Family Code of the Russian Federation, whereas the relations of former spouses go beyond family relations and the norms of the Civil Code of the Russian Federation apply to them. It is concluded that the autonomous regime of regulation of property relations of spouses is more preferable and allows to avoid the participation of the law enforcer in the process of legal regulation, which, in turn, eliminates the need to fi ll in the gaps by analogy of the law. The novelty of the work lies in highlighting additional meanings in the interpretation of the studied norms of the Family Code of the Russian Federation and the formation of the author's point of view on the groups of property relations arising from the regulation of relations that give the right to change the property regime. The study is based on modern doctrinal approaches, taking into account the analysis of scientific hypotheses, law enforcement practice and reviews of opposing legal positions of the courts. A systematic analysis of the structure of the contractual regime in Russian Family law is carried out, other legal structures regulating the property relations of spouses are determined in order to identify gaps in the normative regulation of marriage and other contracts, and ways to solve them are developed.
On the Formation of the Mechanism of Legal Regulation of Relations Related to Cryptoassets in the Era of Global Digitalization
Authors: Savelyeva Maria
Published: December 2023

The sphere of relations in the fi eld of digitalization is conceptually new and requires understanding and regulation as an international phenomenon. The article examines the historical and technological determinants of the creation of cryptoassets, the peculiarities of the legal regulation of relations related to crypto assets in Russia and foreign countries. Taking into account the achievements in the field of digital technologies, the economic and legal actuals of the global digital market, various types of cryptoassets are characterized, their attributes are listed, and a classification of digital phenomena in the field of law is proposed. The correlation is analyzed and the criteria for distinguishing the new concepts of «digital law», «token», «cryptoassets», «digital currency» and «cryptocurrency» are defined. The paper presents a comparison of the legal regulation of new technological phenomena in Russia and other countries. After analyzing the legal regime of crypto assets, the author comes to the conclusion that the concept of «digital rights» used in international law differs from the concept of «digital rights», which has entered Russian civil law. Conceptual approaches to the legal regulation of digital assets are at the stage of formation, modern practice demonstrates many conflicts, the presence of gaps and the absence of regulatory legislation. The technological aspects of the creation and turnover of cryptoassets are considered, revealing the advantages of blockchain technology, thanks to which a unique digital asset was created that has a revolutionary potential to change the entire global financial system. It is concluded that Russia, as a technological power, should take part in the development of adequate and clear rules for mediating the turnover of digital assets as an extraterritorial phenomenon.

Besides, the article highlights the insufficient practical orientation of criminalistic studies, as well as insufficient feasibility and productivity of suggested practical recommendations on crime investigation. In order to eliminate the abovementioned flaws, the author developed his own recommendations for strengthening cooperation with practical workers, wider use of court and investigation experience in theoretical research, and the use of modern technologies.
Theoretical and Legal Problems in the Sphere of Operative Search Activities
Authors: Melikhov Alekhander
Published: December 2023

In terms of the general theory of state and law, there is a number of problems in ensuring national security within the framework of the goals and tasks of operative search activities of internal affair’s departments. They include insufficient use of dialectic, systemic, functional, structural, specific historical approaches in modern research, and the analysis of the “security” category in isolation from the theory of social systems and the theory of management. The question of judicial technique is still relevant in connection with how accurately the concept of “security” is reflected in legislation, its distinction from similar legal concepts, the identification of its place in the system of Russian law, correlation between security and other functions of law, and a clear definition of the key principles of ensuring security. The doctrinal and normative solution of these problems will be relevant for teaching future lawyers such subjects as “Basics of the Theory of National Security”, “Operative Search Activities”, and other legal disciplines, it will also help specify the role and significance of operative search activities in the implementation of such a function of the Russian state as crime counteraction.
The Use of Information Technologies in Crime Investigation
Authors: Bessonov Aleksey
Published: December 2023

The digitization of various spheres of state and public life not only gives rise to new ways of committing crimes, but also presents new opportunities for crime investigation work. In the modern world, the products of digitization are an important source of evidentiary and search information, they also act as an instrument of detecting and studying digital traces in crime investigation. A separate sphere of research is algorithms of artificial intelligence, and the possibilities of using them in criminalistics and the investigation of criminal activities. Serial crimes are used as an example to showcase the possibility of applying AI algorithms to construct a search portrait of a serial offender, to find serial crimes in a mass of unsolved crimes, and to identify the suspect. Further improvement of preliminary investigation is impossible without the use of modern digital technologies, which sets new tasks for the science of criminalistics.

Published: December 2023

One of the trends in the development of the financial market in recent years is the increased competition between brokers as a result of a massive influx of private investors into the securities market in 2020–2021. Improving competition in the market of brokerage services is one of the conditions to improve the quality of investor service and, as a result, to strengthen the processes of transformation of savings into investments across the economic system of the Russian Federation. Issues related to the competition of brokers in the securities market have not sufficiently explored, while they are extremely important for mobilizing endogenous investment processes. To address this issue the authors investigated the current state and potential for the development of competition among brokers. The study establishes a scientific understanding of the place and role of competition in the brokerage services market, provides classification of competition methods, and describes the model of modern competition in Russian brokerage services market. The authors identified the main problems in the activities of brokers in the context of the development of competitive relations. The result was an analysis and generalization of current trends in the development of competition processes in the field of brokerage and the problems arising from them, as well as the proposal of solutions to the identified problems through the prism of improving competitive relations between brokers.

Authors: Khitrova Tatyana , Pyanzin Stanislav
Published: December 2023

The article deals with the urgent issue of building an information and analytical system that is to be used for solving strategic and operational problems of logistics, which retail and wholesale trade companies are facing currently. The problems of logistics arise in the companies that have significant nomenclature of goods and materials in the conditions of uncertain demand. The diversity in «behavior» patterns of material objects requires the use of numerous models for inventory management within a single system. It is concluded, that this approach cannot be implemented in practice in spite of the high level of scientific elaboration that calculation methods show. The article considers the possibility to select and implement the management model, which fits in with the characteristic features of logistic process in the company and ensures its effective performance through modern information technologies. The authors propose an approach, which allows reducing the dimension of variety of inventory management models given the acceptable level of their generality without decreasing the effectiveness of the results. The text also provides the conceptual provisions for the information system development, which ensure the inventory management models implementation.

Success of the state economic policy depends on a number of external and internal factors, condition of national economy as well as on external economic relations. Implementation of state macroeconomic policy is directly linked to approaches of the state to regulation of its inflation constituent, which became especially relevant during the pandemic.
The article examines the experience of Russia and China in .their conduct of the anti-inflation policy as the countries which were initially oriented to planning economy with intensive industrialization. However after the 90-s of the 20th century the economies diverged in terms of goals and instruments used for implementation of their macroeconomic policy.
By analyzing the existing theoretical and factual materials, the article demonstrates the link between inflation rate in the country and some factors. These factors include: instruments of national monetary policy; level of industrialization in the country and competitiveness of national industrial sector; dependence of national economy developments on world oil prices (commodity dependent production and export); participation of the country in the sanction policy. The authors expect that the inflation rate in Russia will further exceed the corresponding figure in China.

Introduction: Crusted scabies are a rare manifestation of scabies characterized by uncontrolled proliferation of mites in the skin. Crusted scabies are a severe variant of highly contagious scabies. Various cutaneous, neurologic and immunologic diseases have been described to predispose to crusted scabies. Case presentation: The presented case is a 7-month-old male. He was hospitalized at the Clinic of Dermatovenerology, due to hyperkeratotic changes in the palms and food, papules throughout the body, and nail changes all of these accompanied by scratching. Initially, it was diagnosed as atopic dermatitis, hyperkeratosis palmoplantaris, and onychomycosis mani. The changes had started to appear five months ago. Also, the mother of the child presents the papules throughout the body, also associated with itching as classical scabies. Conclusion: Crusted scabies are a severe variant of highly contagious scabies. Is known the failure of the immune system to suppress the proliferation of the mite is an important cause of crusted scabies development. Crusted scabies usually do not present as an acute eruption as in classical scabies. The eruption is slow in onset and insidious in progression. In the present case, we learned that in the stimulation of the condition, there was a major role in the application of topically fluoride steroids.

Published: December 2023

In this study, a manganese dioxide (MnO2/polyaniline (PANI)/ single-walled carbon nanotube (SWCNT) nanocomposite electrode was prepared for pseudo-supercapacitors. To reduce the internal resistance of the electrode, increase the capacitance stability, and reduce the cost of single-walled carbon nanotubes, SWCNT was subjected to two-step acid etching. The purity of SWCNT was improved from ~95% to 99.98%. In addition, SWCNT was functionalized by this process. Thus, a nanocomposite was formed by coating PANI around SWCNT. MnO2/PANI/SWCNT were synthesized using the hydrothermal method. Morphological, chemical and thermal analyses of the synthesized nanocomposite structure were carried out. In addition, X-ray diffraction (XRD) was used to determine the crystal structure. Electrochemical analyses were performed using a three-electrode system in a 1 M KOH electrolyte solution. Cyclic voltammetry (CV) and galvanostatic charge-discharge (GCD) measurements were performed. The capacitance of the nanocomposite electrode at 400 cycles was 314 mF/cm2, and the capacitance retention stability was calculated at 73.24%. The results showed that the capacitance stability was high, and the supercapacitor was sensitive to redox reactions.
