The study aimed to analyze changes in the clinical and epidemiological aspects of HIV-associated cryptococcal meningitis (CM) patients and to identify factors influencing their prognosis. Clinical data of patients with HIV-associated CM treated in Shanghai, China between 2013 and 2023 were collected. This study included 279 cases, 2.89% of AIDS patients, showing a yearly decrease in CM prevalence among AIDS patients (p < 0.001). Overall mortality was 10.39% with rates declining from a 2013 peak of 15.38% to 0% in 2023 despite no significant temporal pattern (p = 0.265). Diagnosis took an average of 18 ± 1 days post-symptoms, and admission CD4 counts averaged 29.2 ± 2.5 cells/μL, hinting at a non-significant decline. Frequent symptoms included fever (62.4%), headache (61.6%), fatigue (44.1%), and appetite loss (39.8%), with younger patients more likely to initially show signs of meningeal irritation. Logistic regression analysis underscored the prognostic importance of cerebrospinal fluid (CSF) white blood cell (WBC) count and procalcitonin levels. Over the decade spanning from 2013 to 2023, the incidence and mortality rates of CM among AIDS patients exhibited a downward trend. The average duration from the onset of CM to confirmation of diagnosis remained prolonged. CSF WBC count and procalcitonin levels were associated with unfavorable outcomes.

Granuloma is a crucial pathological feature of tuberculosis (TB). The relationship between CD4+ T cells in both peripheral blood and granulomatous tissue, and the integrity of granulomas in Human Immunodeficiency Virus (HIV)–MTB co-infection, remains unexplored. This study collected biopsy specimens from 102 TB patients (53 with HIV-MTB co-infection and 49 only with TB). Hematoxylin and eosin (HE) staining and immunohistochemical staining were performed, followed by microscopic examination of the integrity of tuberculous granulomas. Through statistical analysis of peripheral blood CD4+ T cell counts, tissue CD4+ T cell proportion, and the integrity of granulomas, it was observed that HIV infection leads to poor formation of tuberculous granulomas. Peripheral blood CD4+ T cell counts were positively correlated with granuloma integrity, and there was a similar positive correlation between tissue CD4+ T cell proportions and granuloma integrity. Additionally, a positive correlation was found between peripheral blood CD4+ T cell counts and the proportion of CD4+ T cells in granuloma tissues. Therefore, HIV infection could impact the morphology and structure of tuberculous granulomas, with a reduced proportion of both peripheral blood and tissue CD4+ T lymphocytes.

Published: August 2024

The current study aims to degrade Procion Golden Yellow H-R through ultrasound-induced cavitation coupled with various oxidants. A comprehensive investigation was conducted to examine the impact of parameters, specifically pH, power, and frequency, on the extent of degradation. The primary aim was to optimize degradation by solely utilizing a cavitation reactor where only 23.8% degradation was observed under the established optimum conditions of pH 2.5, frequency of 22 kHz, and power of 200 W. The investigation of the combined process of cavitation with H2O2, Fenton reagent (H2O2/Fe2+), NaOCl, and potassium persulphate (KPS) was subsequently conducted under optimized conditions. The combined operations greatly enhanced degradation with the use of H2O2 loading of 0.1 g/L leading to 53.3% degradation and the H2O2/Fe2+ ratio of 1:0.25 resulting in 94.6% degradation, while the NaOCl quantum of 0.075 g/L yielded 90% degradation and the KPS quantity of 2 g/L resulted in 97.5% degradation in the specific combinations. A toxicity test on two bacterial strains, Staphylococcus aureus and Escherichia coli, was carried out using the original dye solution and after treatment. The various individual and combination processes were compared using the parameters of cavitational yield and total treatment cost. The study elucidates that combining ultrasonic cavitation with KPS is an effective method for treating wastewater containing Procion Golden Yellow H-R dye, especially when implemented at a larger scale of operation.

Published: August 2024

Accurate long–term water resource supply simulation and demand estimation are crucial for effective water resource allocation. This study proposes advanced artificial intelligence (AI)–based models for both long–term water resource supply simulation and demand estimation, specifically focusing on the ShihMen Reservoir in Taiwan. A Long Short–Term Memory (LSTM) network model was developed to simulate daily reservoir inflow. The climate factors from the Taiwan Central Weather Bureau’s one–tiered atmosphere–ocean coupled climate forecast system (TCWB1T1) were downscaled using the K–Nearest Neighbors (KNN) method and integrated with the reservoir inflow model to forecast inflow six months ahead. Additionally, Multilayer Perceptron (MLP) and Gated Recurrent Unit (GRU) were employed to estimate agricultural and public water demand, integrating both hydrological and socio–economic factors. The models were trained and validated using historical data, with the LSTM model demonstrating a strong ability to capture seasonal variations in inflow patterns and the MLP and GRU models effectively estimating water demand. The results highlight the models’ high accuracy and robustness, offering valuable insights into regional water resource allocation. This research provides a framework for integrating AI–driven models with Decision Support Systems (DSSs) to enhance water resource management, especially in regions vulnerable to climatic variability.

To explore the spatial distribution characteristics of soil physical properties and soil erosion in sloping farmland with ridges in the black soil areas of northeast China, sloping farmland with ridges built with woven bags (RW) along the contour lines was selected as the research object, and another sloping farmland was selected as the control (CK). Soil samples were collected from both RW and CK at uniform spatial intervals to measure key indicators of soil properties in the surface layer (0–15 cm), including soil water-holding capacity, soil structure, and annual average soil loss (A). The results showed that: (i) RW exhibited a significantly higher overall field water-holding capacity compared to CK, with soil moisture characteristics more evenly distributed spatially. Soil bulk weight, fractal dimension, and soil aggregate destruction in RW were reduced by 1.09%, 0.65%, and 4.61%, respectively, compared to CK. Additionally, soil total porosity, capillary porosity, mean weight diameter (MWD), and geometric mean diameter (GWD) were more evenly distributed spatially in RW. (ii) On the up-slope, soil water content and DR>0.25 in RW had a higher increase than those of CK. On the mid-slope, soil field water-holding capacity, capillary porosity, MWD, and GWD in RW had a higher increase than those in CK. On the down-slope, RW had a 7.67–10.79% increase in soil water content, saturated water-holding capacity, field water-holding capacity, and capillary water-holding capacity compared to CK, with total soil porosity and soil capillary porosity increasing by 2.84% and 15.51%, respectively. (iii) Annual average soil loss (A) of RW was reduced by 61.85–99.64% compared to CK, based on the China Soil Loss Equation (CSLE). (vi) Soil water-holding capacity and soil structure characteristics of RW showed benefits compared to CK, with the benefits ranging from 1.01 to 1.09, while the benefit of A reached 2.46. This study is significant for understanding the spatial distribution of soil erosion on sloped farmland in black soil areas and for the effective application of soil and water conservation measures.
Degradation of Oxytetracycline in Saturated Porous Media by In Situ Chemical Oxidation Using Oxygen-Doped Graphitic Carbon Nitride and Peroxymonosulfate: Laboratory-Scale Column Experiments
Authors: Nguyen Thanh-Tuan , Kim Do-Gun , Ko Seok-Oh
Published: August 2024

Oxytetracycline (OTC) is frequently detected in groundwater and soil, posing substantial risks to the subsurface environment via persistence, phytotoxicity, changing bacterial communities, and antibiotic resistance. In situ chemical oxidation (ISCO) is one of the best alternatives for removing OTC from groundwater. However, its feasibility has rarely been investigated using columns for which optimal conditions can be obtained for practical applications. Thus, a system consisting of oxygen-doped graphitic carbon nitride (OgCN) and peroxymonosulfate (PMS) (OgCN/PMS) was tested for OTC removal using continuous-flow experiments with columns packed with sand and glass beads (GBs). The sand column exhibited better adsorption and degradation of OTC than the GB column in pulse injection experiments, regardless of whether OgCN was packed. Additional experiments were performed using a column saturated with the OTC solution and another filled with deionized water to simulate ISCO, using GB as the medium, to evaluate the net OTC removal by catalytic oxidation, excluding adsorption. Performance improved with increased OgCN packing, PMS dosage, retention time, and pH. Anions slightly affected the performance due to scavenging and propagation of radicals. These findings indicate the high potential of OgCN/PMS for ISCO and the usefulness of column experiments in field applications.

Published: August 2024

To improve the ride comfort and driving stability of automobiles, an optimal sliding mode control (OSMC) strategy based on the enhanced African vultures optimization algorithm (EAVOA) is proposed. Firstly, the structure and operating principle of a semi-active suspension system (SASS) with a magnetorheological damper (MRD) is comprehensively introduced. Secondly, the OSMC is designed based on a quarter-vehicle suspension model with two degrees of freedom (DOF) to meet the Hurwitz stability theory. Simultaneously, the EAVOA is employed to optimize the control coefficients of the sliding mode surface and the control law parameters. Finally, the EAVOA-OSMC control strategy is utilized to construct the simulation model in MATLAB/Simulink (R2018b), providing a comprehensive analysis for passive suspension systems (PSSs) and suspensions with SMC control. The simulation results demonstrate that the EAVOA-OSMC control strategy outperforms SMC controllers, offering a better control performance in real application.

Published: August 2024

Se estudió el crecimiento de 208 lotes de camarones en condiciones comerciales en la zona de Guayas (Ecuador) alimentados de forma manual al voleo, con comederos temporizados y con hidrófonos. Solo aparecieron diferencias significativas en la Tasa de Crecimiento Específica (TCE) a favor de la alimentación con los hidrófonos, pero no en el Crecimiento Diario (CD) o el Coeficiente Térmico de Crecimiento (CTC). No aparecieron diferencias significativas en el crecimiento de los lotes en función del mes de inicio del lote, cuando se analizaron mediante TCE o CD, pero sí cuando se empleó el CTC, siendo mayores los valores en junio y julio (con temperaturas del agua menores) frente a los lotes de enero y febrero (con temperaturas mayores) lo que reveló un fallo del modelo de crecimiento térmico cuando las temperaturas fueron superiores a 27 ºC. Al aplicar un límite máximo a la temperatura efectiva de 26 ºC, las diferencias desaparecieron, lo que sugiere su inclusión en el modelo CTC para camarón.

Light verb constructions are usually viewed as idiomatic, fixed patterns in linguistic literature (see, for example, Forgács 2015). However, corpus data show that such constructions may exhibit variability, inviting potential exploration from a synonymy perspective. This is exemplified by constructions like barátságot köt [lit. ‘tie a friendship‘] ~ barátságot sző [lit. ‘weave a friendship‘] ~ barátságot épít [lit. ‘build a friendship‘], all conveying the meaning ‘make friends‘. In this particular case study, I investigate patterns (constructional schemas, in brief: constructions) within the construction N-ba/be ‘into N‘ + V, focusing on constructions such as feledésbe V [lit. ‘become forgotten‘ where feledésbe means ‘into oblivion‘], homályba V [lit. ‘become obscure‘ where homályba means ‘into obscurity‘], and sötétségbe V [lit. ‘become dark‘ where sötétségbe means ‘into darkness‘). More specifically, I analyze vari-ations of these light verb constructions (e.g., homályba vész [lit. ‘be lost into obscurity‘] ~ homályba szürkül [‘fade into oblivion‘]), leading to the identification of synonym groups. My research, primarily utilizing the Hungarian National Corpus 2 [Magyar Nemzeti Szövegtár 2], aims to es-tablish, on one hand, which term(s) may assume centrality within synonym circles based on verb variation and the reasons behind it. On the other hand, it seeks to determine the semantic relationships among the aforemen-tioned three circles of synonymy, exploring motivations for both similarities and differences.
Integration of ICT in Schools: Context-Aware ICT Appropriation (CAIA) Model
Authors: Kennedy Ian , Cronjé Johannes
Published: August 2024

The integration of Information and Communication Technology (ICT) into South African schools is problematic due to access inequalities. This study investigated the dynamics of access to and use of ICT in the context of the COVID-19 pandemic. The qualitative study used a phenomenological approach based on a posthuman philosophical framework and used the Actor-network theory (ANT) as a methodological approach to educational technology. Van Dijk's cumulative access model, combined with Jansen's dimensions of digital inequality, was employed as a theoretical and conceptual framework. ANT was used to identify the various actors involved in the process, to examine their interactions, to understand the use of technology, and to assess their integration into educational practices. The study confirms that access does not follow a simplistic linear progression of continuous phases and proposes the Context-Aware ICT Appropriation (CAIA) model that encompasses a broader contextual approach. This research supports the need for a more complex and nuanced understanding of the multifaceted concept of access to ICT, which more accurately reflects how teachers actively interact with technology in an increasingly technology-driven society. The study has contributed to the theoretical and practical aspects of the field and laid the foundations for future research. It is essential to assess the practical effectiveness and capacity of the CAIA model to overcome the limitations of isolated technology interventions. The researcher advocates for future studies to evaluate the applicability and efficacy of the proposed CAIA model in the real world.

Проанализирована лесоводственная эффективность первого приема двухприемных чересполосных постепенных рубок, выполненных 22 года назад в насаждениях сосняка бруснично-багульниково-мшистого Западно-Сибирского северо-таежного равнинного лесного района. Экспериментально доказано отсутствие ветровала и сухостоя в оставленных на доращивание полосах древостоя, а также усыхания тонкомера и подроста предварительной генерации в вырубаемых полосах. Отмечается, что за 22 года, прошедших после первого приема рубки, в вырубленных полосах сформировались сложные 2-ярусные насаждения. При этом верхний ярус сформировался из тонкомера и не подлежащих рубке деревьев, а второй - из подроста ели предварительной генерации и березы сопутствующей генерации. К положительным последствиям чересполосной постепенной рубки следует отнести увеличение доли сосны сибирской (Pinus sibirica Du Tour.) в составе формирующихся древостоев. Для увеличения доли сосны обыкновенной в формирующихся молодняках рекомендуется проведение минерализации почвы за 3-5 лет до первого приема рубки или сразу после его проведения. Замена сплошных, особенно широко лесосечных, рубок на чересполосные постепенные в сосняках северной подзоны тайги Западной Сибири обеспечит предотвращение нежелательной смены пород, сохранение насаждениями защитных функций и биологического разнообразия видов, не прибегая к искусственному лесовосстановлению.

The article touches upon the silviculural analysis of two modes strip gradual felling of the first mode carried out 22 years ago in vaccinium - ledum - mossy pine stands in West Siberian north taiga plain forest area. Experimentally was proved the lack of windfall and deadwood in stand strips left for completion of growing as well as the lack of toner drying and preliminary generation undergrowth in cut over stripes. It is noted that for 22 years after the first harvesting in cut over stripes a complex two-tier planting was formed. At the same time the upper tier was formed from a tonometer and trees that could not be cut and the second from undergrowth of the spruce of preliminary generation and associated generation birch. To the positive consequences of strip gradual felling it should be pointed out the increasing share of Siberian pine (Pinus sibirica Du Tour.) in composition of stands being formed. To crease the share of common pine in forming young growth it is recommended that soil mineralization should be carried out 3-5 years before the first harvesting or immediately after its carrying out. Replacing clear, especially wide logging by strip gradual felling in the northern taiga subzone in western pine forests will prevent undesirable change of species preservation of protective function and biologic diversity of species by planting without resorting to artificial reforestation.

В статье приведены результаты исследований по изучению влияния различных концентраций ауксина ИМК и добавки Экогеля на процесс корнеобразования красной смородины на этапе «укоренение in vitro». Красная смородина - зимостойкая и засухоустойчивая ягодная культура. Для получения высоких и регулярных урожаев красной смородины при закладке плантаций необходимо использовать высококачественный оздоровленный посадочный материал, полученный методом клонального микроразмножения. Ведущую роль при размножении растений играют регуляторы роста, позволяющие управлять процессами регенерации. Для каждой культуры (иногда - сорта) подбор концентраций регуляторов роста осуществляется индивидуально. Выявлено, что количество корней у растений-регенерантов красной смородины увеличивалось при повышении концентрации в питательной среде ауксина ИМК от 0,5 до 1,0 мг/л. При добавлении в питательную среду Экогель 0,5 мг/л оказывает благоприятное влияние на процесс корнеобразования. Добавление в питательную среду MS ауксина ИМК способствует значительному увеличению количества корней у растений-регенерантов смородины в 1,7-2 раза, их суммарной длины - в 1,5 раза по сравнению с контролем. Наличие в питательной среде Экогеля в концентрации 0,5 мг/л способствует увеличению количества корней в среднем от 5,1 до 5,4 см.

The results of studies on the effect of various concentrations of auxin IMC and Ecogel additives on the root formation of redcurrant at the “in vitro rooting” stage. Red currant is a winter-hardy and drought-resistant berry crop. Use high-quality healthy planting material of red currant obtained by the method of clonal micropropagation is necessary to obtain high and regular yields. The leading role in plant propagation is played by growth regulators, which make it possible to control regeneration processes. The selection of concentrations of growth regulators is carried out individually for each culture (sometimes - varieties). The number of roots in regenerant plants of redcurrant increased with an increase in the concentration of auxin IMC from 0,5 to 1,0 mg/l in the nutrient medium. The addition of Ecogel 0,5 mg/l to the nutrient medium has a beneficial effect on the root formation process. The addition of auxin IMC to the MS nutrient medium contributes to a significant increase in the number of roots in currant regenerant plants by 1,7-2 times, its total length - by 1,5 times compared to the control. The presence of Ecogel 0,5 mg/l in the nutrient medium contributes to an increase in the number of roots on average from 5,1 to 5,4 cm.

Полученные результаты исследований свидетельствуют о том, что пероральное применение пробиотического штамма E. faecium L3 на фоне дисбиоза кишечника способствует более быстрому восстановлению ферментов, участвующих в конечном гидролизе белков, жиров и углеводов, а также отмечается выраженная динамика восстановления микробиоценоза кишечника у животных. В результате проведенных исследований установили, что у больных гастроэнтеритом поросят через 14 дней от начала применения Enterococcus faecim L3 в кишечной микробиоте отмечалось снижение содержания Escherichia coli и повышалось содержание лактобацилл и энтерококков (по сравнению с контрольной группой животных). При этом отмечено повышение активности ряда кишечных пищеварительных ферментов (α-амилаза, мальтаза, аминопептидаза N) и снижение активности щелочной фосфатазы. Таким образом, применение пробиотического препарата на основе штамма Enterococcus faecim L3 поросятам в период отъема восстанавливает состав кишечной микробиоты и повышает активность ключевых кишечных пищеварительных ферментов, что ускоряет адаптацию организма животных к новому типу кормления, положительно влияет на обменные процессы, стимулирует рост животных.

The results, which have been obtained, indicate that the oral administration of the probiotic strain E. faecium L3 against intestinal dysbiosis promotes the rapid restoration of enzymes involved in the hydrolysis of proteins, fats and carbohydrates, as well as a pronounced dynamics in the restoration of intestinal microbiocinosis in animals. As a result of the studies, it was found that in the piglets with gastroenteritis 14 days after the start of using Enterococcus faecim L3, a decrease in the content of Escherichia coli was noted in the intestinal microbiota, and the content of lactobacilli and enterococci increased (compared with the control group of animals).At the same time, an increase in the activity of a number of intestinal digestive enzymes (α-amylase, maltase, aminopeptidase N) and a decrease in the activity of alkaline phosphatase were noted.Thus, the use of a probiotic preparation based on the Enterococcus faecim L3 strain for piglets during weaning, restores the composition of the intestinal microbiota and increases the activity of key intestinal digestive enzymes, which accelerates the adaptation of the animal organism to a new type of feeding, positively affects metabolic processes, stimulates the growth of animals.

The article presents data for 2017-2019 on the yield and productivity of crops of arable (corn-spring wheat - oats) and grain-steam with busy steam (busy steam: peas with oats - spring wheat - spring wheat) crop rotations in the Northern forest-steppe of the Tyumen region. The output of feed and grain units for two studied crop rotations is presented. The productivity of grain crop rotation with a busy ferry higher productivity of crop rotation on grain-0.15 t of fodder units/ha, and the output of grain units grain crop exceeded the grain with a busy ferry 0.56 t/ha. The yield of wheat grain after annual grasses (predecessor) in the grain crop rotation with occupied fallow exceeds by 0.92 t / ha the yield of wheat placed after corn in the grain crop rotation. The highest productivity in the grain crop rotation is marked by corn - 5.46 t/ha, which is more than spring wheat by 1.62 t / ha and 0.57 t / ha in comparison with oats. The highest productivity in the grain crop rotation with occupied steam was observed for annual grasses - 5.32 t/ha, wheat first after occupied steam - 4.92 t / ha. units / ha, which is more than the second spring wheat after the occupied pair by 0.52 t. units/ha. In General, the crop rotation productivity was 4.88 t/ha.

Published: August 2024

The article addresses issues pertaining to the teaching of architectural design. These topics have been presented in the context of a didactic project that has been implemented at the Warsaw University of Technology for a duration of 5 years. In 2017, an interdisciplinary and inter-faculty student project was initiated by the Faculty of Architecture at the Warsaw University of Technology. Within the scope of this project, students from five faculties collectively work on a multi-disciplinary building design, employing BIM technology. The fundamental premise of this project lies in fostering close teamwork among students from diverse industries. This coop¬eration entails making joint design decisions, duly considering the requirements of other industries. The coordination and communication within the project team are facilitated through the utilization of BIM tools. The article presents the findings derived from the course, assessing the applica¬tion of such team-based projects in architectural education, and elucidating their significance amidst the changes asso¬ciated with the implementation of new technologies in the realm of design.

This paper attempts to understand how National Architectural Accrediting Board (NAAB) accredited schools of architecture and their faculties have referenced climate change action in required published statements, including school mission statements and faculty biographies. This paper will limit its scope to the first phase of the study, focused on schools in NAAB Region 4, the East Central Region. The paper will present figures and statistics noting the frequency of key terms, while ranking the term value based on internationally recognized documents on climate change action. These findings serve as an initial indication of the level of engagement of architectural educators with climate change action in architectural curricula. The information collected by this study is intended allow the community of architectural educators to better understand the current state of architectural education with respect to this matter, to prompt departmental conversations and commitments, and to ultimately better prepare future architects to address the role of the built environment in the global climate crisis in this time of urgent need.
