Published: July 2024

Asherman's syndrome is a mysterious, multifaceted disease characterized by the formation ofintrauterine synechiae, up to complete obliteration of the uterine cavity. This is a very controversial topicbecause of its pronounced effect on both the reproductive prognosis (infertility, habitual miscarriage) andgynecological symptoms (menstrual dysfunction of the type of oligo-amenorrhea). Although the syndromehas been extensively studied, there is no clear evidence of both its prevention and effective treatment. Themain reason for the formation of intrauterine adhesions is recognized by most authors as endometrial injury.Understanding the pathogenesis of their formation is necessary to prevent the development of endometrialfibrosis and sclerosis. The review article presents in detail the causes of the disease, risk factors, clinicalmanifestations, and methods for diagnosing this syndrome. Therapeutic measures are presented in step-bystep low-traumatic ways to eliminate intrauterine adhesions with subsequent restoration of menstrual andreproductive functions. Particular attention is paid to anti-relapse prevention through the prescription ofintrauterine anti-adhesion gels.

In pediatric practice, septic shock (SS) is a serious, urgent condition with a high incidence and increased risk of death. Intensive therapy in this condition is based on provision of volume-expansion fluid management, prescription of antibiotic medications, and vasopressor support. Urgent care for children is provided in an intensive care unit and includes mandatory determination of the aetiology of SS (by inoculation of blood samples for sterility), provision of venous access and continuous monitoring of vital signs with measurement of lactate levels. The intensity of respiratory support changes according to the following stepwise logic: oxygen therapy – non-invasive ventilation – mechanical ventilation. When providing fluid management to a patient with SS, preference is given to crystalloid solutions. Antibacterial therapy is devised empirically and must be administered within the first hour of ICU admission. If fluid management proves insufficient to ensure stable hemodynamic parameters, vasopressor support is provided by administering inotropic agents, vasodilators and inodilators (norepinephrine, epinephrine, dopamine and dobutamine). Evidence on the effectiveness of corticosteroids in children and adolescents with SS is lacking. Knowledge of the latest algorithms of intensive treatment of SS in pediatric practice will enhance the quality of care and improve the therapeutic prognosis in this category of patients.

Published: July 2024

Glycocalyx (GC) is represented by protein-polysaccharide compounds lining the inner surface of endothelial cells in the form of a gel. GC plays an important role in the regulation of vascular homeostasis, controls vascular wall permeability and microvascular tone, prevents microvascular thrombosis and participates in the regulation of leukocyte adhesion. Damage of endothelial HA is a part and initial link of pathophysiological processes underlying the development of complications of diabetes mellitus (DM). In most cases of DM is accompanied by degradation of HA caused by hyperglycemia, which leads to impaired microcirculatory perfusion and organ dysfunction. Further study of HA, determination of its contribution to the development of diabetes complications is a very promising area of research. In this review, we analyze the main mechanisms of destruction and the role of HA in the pathophysiological mechanisms of the development of DM complications. Although numerous studies indicate a significant role of HA dysfunction in the development of micro- and macroangiopathies in the outcome of diabetes, many aspects of pathophysiological processes are still unexplored and require further research.

Authors: Mihsen Hayder Hamied , Hussain Alaa Frak , Hatem Raghad Saad
Published: July 2024

Background: Mesoporous materials like MCM-41 silica are highly regarded for their structural features and applications in adsorption and catalysis. This study enhances MCM-41's ability to adsorb cobalt and copper ions by introducing amine and Schiff-base groups, boosting its affinity for these pollutants and aiding in their removal from water solutions. Aims: To prepare MCM-41@NTPE and MCM-41@NTPE-BSAL and use them to adsorb heavy pollutants like cobalt and copper divalent ions from aqueous solutions. Methods: Mesoporous materials (MCM-41@NTPE and MCM-41@NTPE-BSAL) derived from rice husk were used as low-cost adsorbents for the adsorption of Co(II) and Cu(II) ions from aqueous solutions. Uptake experiments were performed to determine adsorption parameters like ion concentration, pH, exposure time, and adsorbent mass. Results: MCM-41@NTPE and MCM-41@NTPE-BSAL were characterized by FT-IR, FESEM-EDX, TEM, N2-adsorption–desorption, XRD,AFM and TGA/DTA. FT-IR confirmed the presence of silanol and siloxane groups. XRD and TEM indicated highly ordered hexagonal arrangements. N2–adsorption–desorption analysis revealed average pore diameters of 42.468 nm and 40.417 nm, total pore volumes of 0.094 cm3g?1 and 0.3384 cm3g?1, and specific surface areas of 8.873 m2g?1 and 37.802 m2g?1 for MCM-41@NTPE and MCM-41@NTPE-BSAL, respectively. TGA showed three mass reduction steps. Adsorption assessment showed pH 6 and 5 were optimal for Co(II) and Cu(II) uptake, respectively, and uptake increased with initial concentration and exposure time. Discussion: XRD confirmed the hexagonal mesoporous structure, while BET analysis displayed amorphous natures. TGA suggested MCM-41@NTPE and MCM-41@NTPE-BSAL have potential for stability, although decomposing between 15-900°C. Electron microscopy revealed ordered hexagonal arrangements. The materials demonstrated high efficacy in extracting copper and cobalt ions from aqueous solutions. Conclusions: Two mesoporous silica materials (MCM-41@NTPE and MCM-41@NTPE-BSAL) were prepared from rice husk by functionalizing MCM-41. Adsorption assessment showed uptake depended on exposure time, pH, initial concentration, and adsorbent mass. MCM-41@NTPE-BSAL exhibited better ion uptake than MCM-41@NTPE.

Enhancing Patient Outcome Predictions Through Differential Privacy with Optimized RNN Model Applied to Electronic Health Record
Authors: Ritunsa Mishra
Published: July 2024

This study introduces a novel method for predicting patient admission and discharge events using Electronic Health Records (EHR) while prioritizing the protection of personal privacy. Our approach utilizes a Simple Recurrent Neural Network (RNN) model enhanced with a Differential Privacy mechanism to strike a balance between high-accuracy outcome predictions and the confidentiality of patient data. At the core of our methodology is the application of a Simple RNN to EHR data, which facilitates the prediction of whether a patient will be admitted to or discharged from a healthcare facility. To strengthen data confidentiality, we integrate Differential Privacy by injecting controlled noise into the dataset, ensuring that our model’s predictions preserve the privacy of individual patient records.
We conducted experiments using six different classifiers to implement our privacy-preserving prediction strategy. Among these, the Random Forest classifier emerged as the most accurate, proving the effectiveness of our method in providing reliable predictions without compromising privacy. In contrast, the XG Boost classifier showed the least precision, indicating some limitations in its ability to balance privacy with predictive accuracy. This research significantly advances the field of healthcare informatics by presenting a sophisticated solution that combines cutting-edge predictive models with stringent privacy safeguards. Our findings highlight the critical need to maintain a delicate balance between achieving precise clinical predictions and upholding the moral responsibility to protect patient privacy in the modern landscape of digital health records.

Objective: The percent-free prostate specific antigen (%fPSA) could enhance total PSA (tPSA) with regards to early prostate cancer detection by increasing its specificity. However, due to significant physiologic differences across races, the optimal cut-off level for %fPSA may vary. We aimed to determine optimal %fPSA cut-off level for Thai men aged between 50 to 80 years whose tPSA score ranged from 4-10 ng/mL and to evaluate its corresponding diagnostic properties, specifically sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The secondary endpoint is the relationship between Gleason Grade Group and %fPSA value. Materials and Methods: A total of 184 male patients from age 50-80 years whose tPSA was between 4-10 ng/ml were enrolled onto the study. Their %fPSA were measured before undergoing transrectal ultrasonography (TRUS) guided prostate biopsy, which procured at least 10 cores. All histologic reports were reviewed and confirmed for further analysis. Results: Out of the 184 patients registered the final diagnoses were 31 (16.84%) were positive for prostate cancer and the other 153 (83.16%) had benign prostate hypertrophy (BPH). At %fPSA cut-off of ≤ 10%, the sensitivity would be 22.6%, specificity 95.4%, PPV 50.0% and NPV 85.9%. However, at a %fPSA cut-off of ≤ 20%, the sensitivity was 77.4%, specificity 32.7%, PPV 18.9%, and NPV 87.7%. The %fPSA value has a direct relationship with sensitivity and NPV whereas it is inversely proportional to specificity and PPV. Lower %fPSA is associated with higher risk of prostate cancer. The area under the curve (AUC) of ROC curve was 0.65. The incidence of prostate cancer among patients with Gleason Grade Groups 1, 2, 3, 4, and 5 were 41.94%, 32.26%, 16.13%, 6.45%, and 3.23% respectively. The mean %fPSA scores among those groups were 14.75%, 17.64%, 10.19% ,13.33%, and 15.65% respectively. Conclusion: The decision to undergo prostate biopsy in Thai males with a tPSA score between 4-10 ng/ml can be guided by %fPSA, which proved to be an effective and useful predictive tool. The cut-off level of %fPSA ≤ 20% had the highest diagnostic properties in Thai men in our study which yielded a sensitivity of 77.4%, specificity of 32.7%, PPV of 18.9%, and NPV 87.7%. If %fPSA was ≥ 30%, there was no risk of prostate cancer in this cohort. In addition, with regard to disease severity, we found that %fPSA level is not associated with the Gleason Grade Grouping.
Techno-Economic Assessment of Electricity Generation From a Medium-Scale CSP-PV Hybrid Plant Using Long-Duration Storage
Authors: McGregor Craig , Pretorius Johannes , Attieh Annitta , Hoffmann Jaap
Published: July 2024

The South African electricity sector is transitioning from a single utility buyer model to an open market model due to increasing utility tariffs, the energy crisis, sustainability goals, and enabling legislation. As a result, the private sector is seeking to procure private power generation technologies, with solar photovoltaics (PV) and onshore wind being the primary choices. However, the integration of these technologies is limited due to their variability and lack of dispatchability. Concentrating solar power (CSP) tower technology combined with long-duration storage is gaining traction in high solar resource regions due to efficiency improvements and cost reductions. This paper evaluates a medium-scale CSP-PV hybrid plant’s technical and economic feasibility in South Africa, focusing on cost savings, energy security, and sustainability. The study identifies a hybrid plant suitable for large power users, with independent power producers (IPPs) developing such a plant using non-recourse project finance and energy sold to large users through long-term power purchase agreements (PPA). The first-year PPA tariffs are determined using a typical project finance model developed for local market conditions. Depending on the plant design and the off-taker’s utility tariff structure, the plant offers cost savings (and average tariffs) ranging from 9.25% (at 78 USD/MWh) to 17.58% (at 81 USD/MWh). Hybrid plants are expected to become more feasible and “bankable” with improving technology and decreasing costs in South Africa.

Authors: Morosini Ettore , Rodriguez de Arriba Pablo , Salah Salma I. , Illyés Viktoria , Guerif Xavier , Ruggiero Marco , Di Marcoberardino Gioele , Manzolini Giampaolo
Published: July 2024

This work summarizes the methodology developed within the H2020 EU project SCARABEUS for the analysis of innovative CO2-based mixtures used as working fluid in transcritical cycles for CSP applications. By adding a specific quantity of carefully selected dopant to CO2 it is possible to reach a high mixture critical temperature, suitable for air cooled cycles at very high minimum temperature in hot environments with high efficiencies. Along the methodology, some results related to the design of the turbine and the heat exchangers for the innovative mixtures are presented, including a focus on the system integration between the power block and the solar plant: as such, these results can be considered as interesting research outcomes to widen the knowledge on innovative solutions for efficient power cycles. The new power cycles are foreseen to drastically increase the profitability and cut the specific cost of CSP systems with respect to the state-of-the-art
Vacuum Loss Detection of PTC in CSP Plants via Temperature-Sensors
Authors: Kraft Thomas , Bern Gregor , Rohani Shahab , Schmitz Mark , Platzer Werner
Published: July 2024

The efficient operation of a solar field is an essential factor for the commercial operation of a concentrating solar power (CSP) plant. In addition to predictive control for the highest possible constant outlet temperature at high mass flow, efficient operation also includes early detection of defective components and heat losses. This work presents a method for non-invasive heat loss detection as a strong indication for vacuum losses, based on measured operational data of Andasol III, an operating 50 MW parabolic trough collector (PTC) plant located in southern Spain. To detect vacuum losses via this method, mass flow rate and temperature reduction are determined separately for each individual loop via the analysis of a short-term temperature rise of the heat transfer fluid (HTF) during preheating. While the temperature reduction was measured directly, the mass flow was determined via the thermal time-of-flight (ToF) method using the same installed temperature sensors. By measuring thermal step responses during the preheating of the solar field at nighttime operation, the influence of fluctuating direct normal irradiance (DNI), misalignment of the absorber tubes and an offset in collector focus was circumvented. In the scope of the presented work, single loops were detected, which show a higher heat loss at lower mass flow rate and therefore have an increased probability of a higher vacuum loss. Better localization and early detection of these vacuum losses would allow the corresponding absorber tubes to be renewed at the economically and environmentally best time, improving the efficiency of the solar field and thus the entire CSP plant.

Published: July 2024

Introduction: Understanding the meaning and significance of comfort for people in palliative care can be a challenge for nurses when defining care. Objective: To map the available scientific evidence on nursing care that promotes comfort for people in palliative care. Materials and methods: This is a literature review based on the Joanna Briggs Institute and PRISMA-ScR guidelines. A complete search was conducted in the Medline Complete, Cinahl Complete, Scopus, Web of Science, Repositório Científico de Acesso Aberto de Portugal, and OpenGrey databases. Primary studies were included, with quantitative, qualitative, or mixed methods designs, published between January 2014 and March 2023, in Portuguese, English, or Spanish. The search syntax was adjusted for each database. A combination of MeSH, text words, and indexing terms using the boolean operators AND and OR was used. Truncation * was used to enhance the search. Results: 681 articles were found, of which 239 were duplicates. A total of 442 studies were analyzed and 409 were excluded for not reflecting the theme. The full texts from 33 articles were retrieved, of which eight were included in the review. Comfort-promoting nursing care integrates the physical, psychospiritual, environmental, and sociocultural dimensions. Of particular relevance are the implementation of pharmacological measures, respect for religious and cultural beliefs, encouragement for the presence of family members, communication, and the relaxation of rules. Conclusions: Promoting comfort for patients in palliative care includes direct care and support for the family. The individualization of care and the response to specific needs can result in relief, ease, and transcendence.
Protagonismo negro e as novas abordagens da historiografia do pós-abolição
Authors: Santos Fernando de Oliveira dos
Published: July 2024

A publicação do livro Protagonismo negro em São Paulo: História e Historiografia em outubro de 2019, sinaliza para os resultados fecundos de um campo de pesquisa que tem se consolidado na historiografia brasileira, qual seja, o pós-abolição. Todavia, a elaboração dessa obra evidencia muito mais do que isso se pensarmos que o desenvolvimento de um determinado ramo da historiografia não ocorre de forma estanque ao desenvolvimento da consciência coletiva. É fato assente que não apenas a historiografia, mas outras áreas das ciências humanas têm se debruçado no estudo de temas relacionados às questões raciais. Em certa medida, isso é resultado do entrelaçamento de vários processos, como as demandas pautadas pelos movimentos sociais, os debates que emergem nos campos acadêmico, político, educacional, nas redes sociais, e até mesmo os eventos e as influências do cenário internacional são componentes dessa atmosfera reflexiva.

Por fim, propomos a hipótese de que a partir de textos do autor voltados para o debate contemporâneo no interior da esquerda e da sociedade britânica como um todo, é possível localizar as motivações e as preocupações políticas que o levaram a se concentrar sobre o tema.

A negregada instituição
Authors: Salvadori Maria Angela Borges
Published: July 2024

Para os historiadores que trabalham com temas da genericamente chamada “cultura popular” inúmeras dificuldades se apresentam. Uma delas é a própria impossibilidade de usar um termo tão genérico para conhecer e analisar essa realidade. Contudo, se essa dificuldade existe, o modo de encará-la tem trazido resultados surpreendentemente bons pois, ameaçados por generalizações simplistas, os historiadores percorrem um caminho de pesquisa intensa e recortam objetos bastante específicos, procurando olhá-los por dentro e também nas relações que estabelecem com outros grupos sociais. Diante da dificuldade em precisar este e outros conceitos, também enfrentada por Eugênio na introdução, a saída é tentar entendê-los tal como existiram em determinados momentos históricos (ver, por exemplo, a introdução, especialmente a página 2).

Blockchain technology in financial services: enhancing security, transparency, and efficiency in transactions and services
Authors: Emmanuel Paul-Emeka George  , Courage Idemudia  , Adebimpe Bolatito Ige
Published: July 2024

Blockchain technology revolutionizes financial services by enhancing security, transparency, and efficiency in transactions and services. This paper examines the fundamental aspects of blockchain, including its core concepts and components, and explores its application in financial services. Blockchain's cryptographic hashing, decentralization, and immutability significantly improve security by preventing tampering and reducing fraud risks. Increased transparency through immutable audit trails, real-time updates, and open ledgers fosters trust among customers, regulators, and institutions. Furthermore, blockchain streamlines operations by automating processes, reducing intermediaries, and expediting transactions, resulting in substantial cost reductions and improved efficiency. Despite these advantages, challenges such as scalability, interoperability, regulatory uncertainty, and environmental impact must be addressed for widespread adoption. The prospects of blockchain in financial services are promising, with potential applications in decentralized finance, digital identity verification, and central bank digital currencies. This paper underscores the transformative potential of blockchain technology in creating a more secure, transparent, and efficient financial ecosystem.
Defending the Candid Gaze: Theory, the Archive, and Depolicing Street Photography
Authors: Mountfort Paul
Published: July 2024

Since practically the dawn of photography, there have been concerns over street photography’s invasive and potentially exploitive nature, from late nineteenth-century tropes of pests and “sneaky characters” trailing women in public parks to more recent panics over “camera fiends” and even state security warnings of the need to be vigilant of photographers potentially casing infrastructure for terrorist attacks. This article argues, using potted history and critical theory, that such straw-man arguments distract from the real dangers that the policing and curtailment of public photography pose, characteristic, as they are, of authoritarian regimes where control over taking and circulating images is an integral part of oppressive state and corporate apparatuses. Street photography’s implicit role in the construction of an archive of aesthetic and documentary value can be understood as a type of resistance to such threatened microfascisms.
Politics and Violence in Representation of Acid Attack Victims in the Media: A Feminist Discursive Perspective
Authors: Sharma Saumya
Published: July 2024

In recent times, narratives of acid attack survivors have become common in the media (newspapers and magazines), showcasing them simultaneously as fashion models and victims of a heinous crime. In a similar vein, the Hindi film Chhapaak underscores the barbarity of an acid attack and the subsequent struggles for justice by the protagonist. Drawing on feminist critical discourse analysis and insights from Nancy Fraser on cannibal capitalism, this article analyzes the discursive construction of acid assault victims through select extracts from media articles and the film to highlight the politics of representation of the survivors and their ordeals against patriarchal and androcentric arrangements in society. Linguistic analysis (through speech acts, vocabulary, and presupposition) reveals contradictory discourses of celebration and discrimination in the media in relation to fashion, where the acid survivors are used not only to increase awareness about the offense but also to promote sales of garments. The discourses of rampant unemployment, gender-based oppression, and racial violence, despite laws regulating the sale of acid, underscore the cannibalizing tendencies of a capitalist society that seeks to devour and shun women after incapacitating them. Furthermore, the complicity of public agencies (legal, medical, and governmental) hints at apathy, callousness, and the systemic violence symptomatic of a profit-driven capitalist society.
Carved panels in the Council Hall of Stieglitz Academy Museum: artistic sources and iconography
Authors: Карпов А.В. , Мутья Н.Н.
Published: July 2024

Предмет статьи — исследование своеобразия стилистических и иконографических решений Зала Совета Музея училища барона А.Л. Штиглица (1885–1895, архитектор М.Е. Месмахер), истоком которых явились памятники искусства эпохи итальянского Возрождения. Резные скамьи хора церкви Сан-Пьетро в Перудже (La basilica di San Pietro a Perugia), исполненные во второй четверти XVI в., послужили изобразительным источником для создания декоративных панелей скамей в Зале Совета. В статье анализируются особенности иконографии резных панелей, основанной на сочетании орнаментальных и сюжетных мотивов Античности и Ренессанса, что соответствовало задуманной М.Е. Месмахером концепции интерьеров Музея училища как ретроспективы исторических художественных стилей.

The subject of the article is the originality of the iconographic and stylistic solutions of the Council Hall at the Stieglitz Academy Museum (1885–1895, architect Maximilian Messmacher). Art monuments of the Italian Renaissance became the sources of these solutions. The carved benches of the choir of St. Peter church in Perugia (La basilica di San Pietro a Perugia), crafted in the second quarter of the 16th century, served as a pictorial source for the creation of decorative panels of benches in the Council Hall. The article provides the analysis of the features of carved panels iconography based on a combination of ornamental and plot motifs of Antiquity and the Renaissance. This corresponded to Messmacher’s concept of the Academy Museum interiors as a retrospective of historical artistic styles.

В статье впервые представлены материалы о жизни и творчестве скульптора Е.П. Тархановой-Антокольской. Она не получила профессионального художественного образования, ваянием начала заниматься под руководством родного дяди, известного скульптора Марка Антокольского. Елена Павловна принимала активное участие в художественной жизни Петербурга, с успехом экспонировала произведения на выставках в Императорской Академии художеств. Ее натурные зарисовки «Читающая старуха», «Вышивальщица», «Краковский тип», «На балконе» и другие нередко получали положительные отзывы критиков. Единственной известной монументальной работой Тархановой остается надгробный памятник мужу, профессору И.Р. Тарханову, находящийся в Некрополе мастеров искусств (Государственный музей городской скульптуры, Санкт-Петербург). В статье рассматривается история его создания в соавторстве с архитектором Е.Е. Баумгартеном. В 1920–1930 гг. Тарханова-Антокольская продолжала работать в портретном жанре, а также по заказу Института по изучению мозга и психической деятельности создала необычную серию детских бюстов с различными патологическими медицинскими изменениями.

The article presents for the first time materials about the life and work of the sculptor E.P. Tarkhanova- Antokolskaya. She did not receive a professional art education, she began sculpting under the guidance of her uncle, the famous sculptor Mark Antokolsky. Elena Pavlovna took an active part in the artistic life of St. Petersburg, successfully exhibited works at exhibitions at the Imperial Academy of Arts. Her full- scale sketches «The Old Woman Reading», «The Embroiderer», «The Krakow type», «On the Balcony», etc., often received positive reviews from critics. The only known monumental work of Tarkhanova remains the tombstone monument to her husband, Professor I.R. Tarkhanov in the Necropolis of Art Masters (The State Museum of Urban Sculpture, St. Petersburg). The article discusses the history of its creation in collaboration with architect E.E. Baumgarten. In the 1920s and 1930s, Tarkhanova-Antokolskaya continued to work in the portrait genre, and also created, by order of the Institute for the Study of the Brain and Mental Activity, an unusual series of children’s busts with various pathological medical changes.
The problem of comparison analysis of old Russian graffiti
Authors: Точилова Н.Н. , Желомонова Д.К.
Published: July 2024

Древнерусские граффити изучаются на протяжении длительного времени и являются важным источником информации о духовной, политической и повседневной жизни древнерусского общества. Граффити можно разделить на две категории — надписи и рисунки, нанесенные на поверхности предметов и архитектурные плоскости. Много внимания уделяется эпиграфической составляющей граффити, в то время как рисунки-граффити, как правило, изучаются лишь в контексте надписей. Однако многие изображения имеют не только сюжет, но и ярко выраженные стилистические особенности. Это позволяет поставить вопрос о необходимости изучения рисунков-граффити методами искусствоведческого анализа, что поможет в дальнейшем расширить представления о духовной составляющей повседневной жизни средневекового человека, а также даст возможность проследить отражение образов высокого искусства в повседневности.

Old Russian graffiti are an important resource of the spiritual, political and daily lives of medieval society. These images were studied for a long time. Graffiti could be divided into two groups–inscriptions and drawings, were traced on surfaces of artefacts and architectural surfaces. Much attention was paid to epigraphy when drawings were researched in a contest of inscriptions. However various images there is more to narrative than stylistic features. This equates to raising a question about the need to study artistic graffiti by methods of Art History. This could further expand ideas about the spiritual component of the daily life of medieval people, and will also provide an opportunity to trace the reflection of images of high art in daily life.
