Published: July 2024

Se realizaron dos estudios para evaluar el surgimiento de descripciones emergentes después de cuatro tipos diferentes de entrenamiento en discriminación condicional de segundo orden, así como sus efectos en pruebas de transferencia y de mantenimiento. En cada experimento se emplearon estudiantes universitarios distribuidos en cinco grupos de cuatro sujetos, cada grupo asignado a un diferente tipo de entrenamiento o a una condición control sin elaboración de descripciones. Se emplearon: a) entrenamiento correctivo con 50% de ensayos con solución; b) entrenamiento correctivo con 100% de ensayos con solución; e) entrenamiento no correctivo con 50% de ensayos con solución; y d) entrenamiento no correctivo con 100% de ensayos con solución. En los dos estudios se utilizaron pruebas de transferencia intramodal y extramodal. En el primer estudio, las descripciones emergentes se elaboraron después del entrenamiento antes de las pruebas de transferencia, mientras que en el segundo estudio las descripciones se elaboraron después de la transferencia. En el primer estudio se observó que el grupo entrenado correctivamente con 100% de ensayos con solución mostró mayor correspondencia y precisión en las descripciones de sus respuestas de igualación, y las ejecuciones en la transferencia y la postprueba correspondieron con el porcentaje de aciertos en el entrenamiento para todos los grupos. En el segundo estudio el grupo entrenado correctivamente con 50% de ensayos de solución mostró el mejor desempeño en adquisición, pero las ejecuciones en las pruebas de transferencia la postprueba y la elaboración de descripciones no correspondieron en muchos de los casos con los porcentajes de aciertos en el entrenamiento. Se examina el papel de la ubicación temporal de las descripciones en la facilitación o interferencia del entrenamiento respecto de la transferencia y el mantenimiento.

Published: July 2024

The article emphasizes that wood is a flammable material, flames spread quickly, which poses a threat to building structures. Therefore, it must be protected by effective means of fire protection. Regulatory and technical documentation is presented, which establishes requirements for the quality of fire protection of wooden structures. Using the example of state reserve enterprises, it is shown that there are many methods of fire-resistant treatment of wooden structures with flame retardants. Among them are the impregnation of wood with inorganic salts and the application of coatings on an organic basis. These include impregnation of wood with inorganic salts and application of coatings on an organic basis. It is shown that the specified methods of processing have disadvantages during application and operation, which include the moistening of wood under the influence of external natural factors, which leads to the dissolution and leaching of salts, increased smoke formation, and the formation of toxic combustion products. The constituent parts of the intumescent coating are proposed and their effectiveness in relation to fire protection of wood is determined. Depending on the content of PVA-dispersion, a change in the coefficient of swelling was determined, which is in the range from 14.3 to 25.1. Thus, it was determined that when mineral fillers are added to the composition of the organo-mineral composition in the amount of 10%, it helps to increase the coefficient of swelling from 30 to 36.7, which is 1.5...1.84 times greater than the value of the coefficient of swelling of the optimal composition of the organo-mineral composition without fillers. The article presents research on the creation of fire-resistant intumescent coatings capable of providing a wide range of fire-resistant and operational properties. After testing samples treated with an intumescent coating, under the action of a burner flame, a sample weight loss of no more than 6% was obtained, and the temperature of flue gases did not exceed 184ºС, which refers the treated wood to the group of non-combustible materials. Thus, the intumescent coating provides the first group of fire protection efficiency.
Keywords: building structures, fire-resistant treatment, state reserve enterprises, intumescent coatings, fire-resistant properties, efficiency.
CITY-STATE IN THE TREATISE BY J. V. ANDREAE: A VISION OF HARMONY AND ORDER
Authors: Fedak A.
Published: July 2024

The article highlights the features of the architecture and urban planning structure of the utopian city-state described by the German theologian Johannes Valentinus Andrea in the treatise «Description of the Republic of Christianopolis» which was written in 1619. The aim of this article is a detailed analysis and graphic reproduction of the urban planning and architectural features of the utopian city described by J. V. Andreae. One of the tasks is to compare the structure of the city-state he recreated with the layout of the utopian settlements of T. More, T. Campanella and A. F. Doni, as those written in approximately the same period and depicting utopian states located on remote islands.
Republic of Christianopolis is built in the shape of a perfect square, symbolizing order and rationality. Each side of the city is of equal length, and all the streets are laid out to form a regular, neat grid. In the center of the city there is a large square with a temple. This temple serves as the spiritual and civic nucleus of the city, underscoring the significance of religion and communal life in a utopian society. The city-state is divided into different zones according to their functional purpose. There are separate plots for residential buildings, administrative buildings, scientific institutes and agricultural areas. Such planning reflects a desire for efficiency and organization.
Residential buildings are organized in such a way that each family has adequate housing with sufficient space for comfortable living. Gardens are located around the houses, which helps to create a public space for communication and interaction between residents. Despite the utopian nature of the society, the city has defensive structures such as walls and towers, which indicate a desire to protect the city from external threats. The article depicts a schematic general plan of the city of Christianopolis, conventional plans and sections of buildings.
A review of the urban design features in J.V. Andreae's utopia compared to those in the works by T. More, A. F. Doni, and T. Campanella reveals common tendencies typical for that era, such as the ideal city shape, a preference for symmetry and centralized planning. It should be highlighted that in the treatise «Description of the Republic of Christianopolis», there is a more distinct zoning of areas and division of the population.
J. V. Andrea created a utopian society where scientific knowledge and Christian faith are harmoniously combined. Christianopolis is depicted as a place where education and spirituality are integrated, reflecting the ideals of its era and the pursuit of knowledge.
Keywords: utopia, symmetrical planning, urban structure, city fortifications, residential buildings.
EFFICIENCY OF USING FIBER CONCRETE AS CORE FOR STEEL CONCRETE COLUMNS OF SQUARE CROSS SECTION
Authors: Berestianskaya S. , Galagurya E. , Kovalov M. , Kravtsiv L. , Opanasenko O.
Published: July 2024

The article examines the effectiveness of using fiber concrete as a core for reinforced concrete columns with a square cross-section. For this, at the first stage, the calculation of a steel-concrete column with dimensions of 100×100×3 mm, length of 500 mm was carried out using as a core a cross-section of concrete grade C20/25. At the next stage of the research, based on the conditions of the same bearing capacity of the columns, cross-sections were selected using fiber concrete with steel and basalt fibers at different values of the thickness of the steel shell. Steel fiber "Chilyabinka" was used, which was introduced at the rate of 32,536 kg/m3 of concrete. Basalt fiber was used with a length of 12 mm, and was added in the amount of 0.2% of the mass of cement. The dependence of the area of the concrete core and the area of the steel shell on the thickness of the steel shell is plotted. A comparison of the cost and characteristics of reinforced concrete columns with the use of ordinary concrete and fiber concrete with two types of fibers as a core cross-section was also carried out: steel and basalt. Based on research, the following conclusions can be drawn that the use of fiber concrete as the core of a steel concrete column of rectangular cross-section significantly improves a number of characteristics. Thus, with the same bearing capacity and thickness of the shell, the cost of a column with a core made of steel fiber concrete is reduced by 15%, weight by 26%, cross-sectional size by 13% compared to concrete without fiber. The cost of a column with a core made of basalt fiber concrete is reduced by 12%, weight by 21%, cross-sectional size by 9% compared to concrete without fiber. By changing the thickness of the steel shell, you can also influence the characteristics of the column, in particular, reduce the cross-sectional dimensions and weight. But at the same time, the cost of the column increases.
Keywords: fiber concrete, steel concrete, column, bearing capacity
EXPERIMENTAL DETERMINATION OF FLOOR PANELS DEFORMABILITY OF A LARGE-PANEL SYSTEM BUILDING AFTER RENOVATION
Authors: Kalmykov O. , Binkevych K.
Published: July 2024

This paper deals with a field tests of prefabricated reinforced concrete floor panels of a multistory building by the method of hydrostatic loading. Object of study is presented by 3 damaged floor slabs of a 9-storey residential building which was hit during the russian invasion. After renovation of panels using the constructive solution which consists of a reinforced build-up layer in the compressed zone (upper part) and additional external reinforcement in the stretched zone (lower part) connected to each other with the help of anchor connections, a series of tests with water loading were set. For creation of loading an inventory pool was used, which was gradually filled with water at a step of 1kN/m2. Maximum created loading level was 5kN/m2 which corresponds to the operational load. After reaching the maximum load, the panels were left under load for 15 hours and then fully unloaded in steps of 1kN/m2. For each panel two type of tests were established: first when panel had both upper and lower part of reinforcement, and second – when lower reinforcement within steel beams was removed. The idea of dismantling of steel beams connected with previously performed numerical analysis which gave to little difference in deflections of panels for these two cases. Deflection measurements at critical locations along with thorough visual inspection were conducted during the loading and unloading cycles. No damage was observed during the in-situ loading and unloading cycles. Maximum vertical deflection for panel before dismantling of beams lies in the diapason of 1.95-2.1mm and 2.31-2.4mm after they were removed. These results meet the requirements of regulatory restrictions on the maximum deflection equal to 20 mm for this structure. Difference in deflection for two cases doesn’t exceed 20% which allows to abandon the use of lower reinforcement in the form of steel beams in the future. As the size of the pool doesn’t cover the whole panel area, the equivalent uniformly distributed load was also calculated using Lira software.
Keywords. Large panel system house, reinforcement, floor panel, method of hydrostatic loading, deflection.

Authors: Ullah Habib
Published: July 2024

The goal of this study is to describe how market orientation and innovation help Small and Medium-Sized Enterprises (SMEs) in Bangladesh had improved their marketing performance. To do this, a sample of 350 managers and Operations Managers from SME Enterprises in Bangladesh was chosen by purposive sampling technique and studied using structural equation modeling (SEM). This research shows that SMEs' performance would improve if they identify and meet customer needs. Furthermore, a company's ability to build a competitive advantage based on innovation and market orientation is directly correlated to the degree to which the company places a high priority on its customers. The study also found that market orientation and innovation have substantial direct and indirect implications on business success through competitive advantage. This means that competitive advantage considerably moderates the effect of market orientation and innovation on marketing performance, suggesting that a stronger business performance is associated with improved competitive advantage. For business success, managers must invest in customer orientation and innovation performance.

Published: July 2024

In this study, a trisodium citrate (TSC)-assisted hydrothermal method is utilized to prepare three-dimensional hydroxyapatite (3D HA). Understanding the role of TSC in the preparation of 3D HA crystals may provide valuable methods to design advanced biomaterials. As one of the indexes of solution supersaturation, the initial pH (ipH) value can not only directly affect the nucleation rate, but also affect the growth of HA crystals. In this work, the effect of the ipH on the microstructure, particle size distribution, and specific surface area of the 3D HA is explored. Results showed that the morphology of 3D HA transformed from a bundle to a dumbbell ball and then a dumbbell with an increase in the ipH. A corresponding mechanism of such a structural evolution was proposed, providing inspiration for the fabrication of innovative 3D HA structures with enhanced biological functionality and performance.

Published: July 2024

Background

Gut microbiota has significant impact on the cardio-metabolism and inflammation, and is implicated in the pathogenesis and progression of atherosclerosis. However, the long-term prospective association between trimethylamine N-oxide (TMAO) level and major adverse clinical events (MACEs) in patients with coronary artery disease (CAD) with or without diabetes mellitus (DM) habitus remains to be investigated.

Methods

This prospective, single-center cohort study enrolled 2090 hospitalized CAD patients confirmed by angiography at Beijing Hospital from 2017-2020. TMAO levels were performed using liquid chromatography-tandem mass spectrometry. The composite outcome of MACEs was identified by clinic visits or interviews annually. Multivariate Cox regression analysis, Kaplan-Meier analysis, and restricted cubic splines were mainly used to explore the relationship between TMAO levels and MACEs based on diabetes mellitus (DM) habitus.

Results

During the median follow-up period of 54 (41, 68) months, 266 (12.7%) developed MACEs. Higher TMAO levels, using the tertile cut-off value of 318.28 ng/mL, were significantly found to be positive dose-independent for developing MACEs, especially in patients with DM (HR 1.744, 95%CI 1.084-2.808, p = 0.022).

Conclusions

Higher levels of TMAO are significantly associated with long-term MACEs among CAD patients with DM. The combination of TMAO in patients with CAD and DM is beneficial for risk stratification and prognosis.

Subsequently, correlation, regression analyses, and receiver operating characteristic (ROC) curves were conducted to assess the associations between amino acids and clinical indicators.

Results

Thirteen different kinds of amino acids were identified in diabetic patients, as compared with normal controls. The Glutamine/Glutamate (Gln/Glu) ratio was negatively correlated with BMI, HbA1c, serum uric acid, and the triglyceride-glucose (TyG) index, while it was positively correlated with HDL-C. Logistic regression analyses indicated that Gln/Glu was a consistent protective factor for both T2D (OR = 0.65, 95% CI 0.50-0.86) and obesity (OR = 0.79, 95% CI 0.66-0.96). The ROC curves demonstrated that Gln/Glu, proline, valine, and leucine provided effective predictions for diabetes risk, with Gln/Glu exhibiting the highest AUC [0.767 (0.678-0.856)]. In patients with T2D, Gln was the only amino acid that displayed a negative correlation with HbA1c (r = -0.228, p = 0.017). Furthermore, HOMA-β exhibited a negative correlation with Glu (r = -0.301, p = 0.003) but a positive correlation with Gln/Glu (r = 0.245, p = 0.017). Notably, logistic regression analyses revealed an inverse correlation of Gln/Glu with the risk of diabetic kidney disease (OR = 0.74, 95% CI 0.55-0.98) and a positive association with the risk of diabetic retinopathy (OR = 1.53, 95% CI 1.08-2.15).

Conclusion

The Gln/Glu ratio exhibited a significant association with diabetes, common metabolic parameters, and diabetic complications. These findings shed light on the pivotal role of Gln metabolism in T2D and its associated complications.

Hydrogen is expected to become a dominant energy vector in a scenario where renewable energies will prevail over other conventional sources. This suggests that beyond its conventional industrial applications, such as in the chemical industry, hydrogen is poised to find numerous additional uses, including serving as a fuel for internal combustion engines. Consequently, global demand is expected to surge significantly, necessitating the implementation of large-scale hydrogen production units from renewable sources. This is particularly pronounced in Europe, where recent energy directives have set ambitious targets in this regard. Consequently, it becomes imperative to evaluate potential locations suitable for hosting these hydrogen production facilities. In this study, particular attention is directed towards photovoltaic-fed water electrolysis as a method for hydrogen production. This choice is informed by the maturity and affordability of these technologies, coupled with the abundant solar energy resource available in Southern Europe. To this end, it is utilized 23 years of hourly meteorological data obtained from the Portuguese Meteorological Service. This dataset enables the development of typical meteorological year files for nearly 90 stations across mainland Portugal. These files were inputted into a model simulating a 120 MWp photovoltaic plant, utilizing the System Advisor Model. The electricity generated by this plant was subsequently used to simulate the hydrogen production using an in-house developed model for the electrolyser. Finally, the simulation results were used to develop the first atlas for Solar Hydrogen production capacity and cost in Portugal. The techno-economic results indicate that annual specific hydrogen production can achieve values above 30 kg/kWp, with the levelized cost of hydrogen below 4.0 €/kg, especially, in the southern regions (Alentejo and Algarve) and the central-east area (Beira Interior). This makes these regions highly attractive for hosting large-scale photovoltaic hydrogen production plants and very competitive in the hydrogen market, especially with neighbouring countries like Morocco and Spain.
Distributionally robust chance-constrained operation of distribution grids considering voltage constraints

Published: July 2024

The distribution grid experiences node voltage fluctuations due to the growing uncertainty of large-scale renewable energy sources A practical solution is establishing a chance-constrained optimal model to deal with the uncertainties. However, using this method needs to know the accurate probability distribution of node power injections, which has limitations in application. Therefore, this paper proposes a distributionally robust chance-constrained optimization method for power grid operation based on the ambiguity set of probability distributions. Firstly, considering voltage security constraints, this paper establishes a chance-constrained model to minimize the cost of active power regulation. Besides, based on the Wasserstein ambiguity set, a linearized method is proposed to convexify the objective function. Moreover, the conditional risk value (CVaR) is applied to convert the uncertain model into a deterministic model. The effectiveness of the proposed method is validated through optimization results obtained for the modified PG&E69-bus distribution grid.

Published: July 2024

Background

Acute febrile illnesses such as typhoid fever, typhus, and malaria are still major causes of hospital admission in many parts of Ethiopia. However, there are substantial gaps in the monitoring systems, which result in a lack of knowledge about the geographic distribution and role of common pathogens, particularly in rural areas. Thus, this study was aimed at assessing the seroprevalence of typhoid fever, typhus, and malaria among suspected acute febrile patients at the MTU Teaching Hospital and Mizan-Aman Health Center, Southwest region of Ethiopia.

Method

A health facility-based cross-sectional study was carried out from July to October 2022. Blood samples were collected from a total of 384 individuals. Widal and Weilfelix direct card agglutination and tube agglutination test methods were used for the Salmonella enterica serotype Typhi (S. typhi) and Rickettsia infections. The diagnosis of malaria was made using thick and thin blood smears. Questionnaires given by interviewers were used to gather information on risk factors and other sociodemographic factors. The data was analyzed using STATA/SE 14.0.

Result

A total of 371 patients were tested for S. Typhi and Rickettsia infections using direct card agglutination and tube agglutination methods. Using the screening test, 20.5% (76/371) patients were reactive either for O or H antigens or both, of which 55.3% (42/76) were reactive by the titration test at the cutoff value ≥ 1:80. About 17.5% (65/371) were reactive to OX19 antigen by card agglutination test, and of which 58.5% (38/65) were reactive by the titration test at the cutoff value ≥ 1:80. The overall seroprevalence of S. Typhi and Rickettsia infections using combined direct card and tube agglutination techniques was 11.3% (42/371) and 10.2% (38/371), respectively. Out of 384 suspected malaria patients, 43 (11.2%) were found positive either for P. falciparum, 27 (7.03%), or P. vivax, 16 (4.2%).

Conclusion

In this study, typhoid fever, typhus, and malaria were found among symptomatic acute febrile patients. To increase disease awareness, it is necessary to provide sustainable health education about risk factor behaviors, disease transmission, and prevention strategies. In addition, improving laboratory diagnosis services and early treatment may also lower the likelihood of potentially fatal consequences.

The rising problem of plastic pollution is becoming one of the major environmental issues for the world. In the ocean, plastics undergo degradation into smaller microplastics (MPs) and nanoplastics (NPs). Wild fish and farmed salmon would likely be exposed to these NPs and MPs both through skin and through skin wounds. Keratocyte cells, located in the skin epithelial layer, are scavenger cells which may remove foreign materials and maintain the salmon’s health. They are therefore first in line to handle and to suffer from MP and NP exposure. While the impacts of MPs have been well studied in many different organisms, much less is known about the effects of NP exposure, particularly at the subcellular level. Here, we have used holotomographic and fluorescence microscopy to show that both skin and corneal salmon keratocyte cells fully internalize 500–1000 nm polystyrene particles, as well as inorganic 500 nm silica particles. The fact that corneal epithelial cells also take up particles is novel. Furthermore, some of these particles likely end up in lysosomal compartments within 2 hours of exposure. Here, we show that both conventional and new modalities of microscopy have a role to play to understand how micro- and nano particles affect epithelial cells.
Causal relationship between type 2 diabetes and common respiratory system diseases: a two-sample Mendelian randomization analysis
Authors: Chen Jie , Zhang Xiaofeng , Sun Gengyun
Published: July 2024

Background

Type 2 diabetes (T2D) frequently co-occurs with respiratory system diseases such as chronic obstructive pulmonary disease (COPD), bronchial asthma, lung cancer, interstitial lung disease, and pulmonary tuberculosis. Although a potential association is noted between these conditions, the available research is limited.

Objective

To investigate the causal relationship between patients with T2D and respiratory system diseases using two-sample Mendelian randomization analysis.

Methods

Causal relationships were inferred using a two-sample Mendelian randomization (MR) analysis based on publicly available genome-wide association studies. We employed the variance inverse-weighted method as the primary analytical approach based on three key assumptions underlying MR analysis. To bolster the robustness and reliability of our results, we utilized MR Egger’s intercept test to detect potential pleiotropy, Cochran’s Q test to assess heterogeneity, funnel plots to visualize potential bias, and “leave-one-out” sensitivity analysis to ensure that our findings were not unduly influenced by any single genetic variant.

Result

The inverse variance weighted (IVW) analysis indicated a causal relationship between T2D and COPD [Odds Ratio (OR) = 0.87; 95% Confidence Interval (CI) = 0.82–0.96; p < 0.05]. No significant heterogeneity or pleiotropy were observed through their respective tests (p > 0.05), and the statistical power calculations indicated that the results were reliable. The IVW analysis showed a negative causal relationship between T2D and bronchial asthma [OR = 0.85; 95% CI = 0.81–0.89; p < 0.05]. However, the IVW under the random-effects model indicated heterogeneity (p < 0.05), suggesting instability in the results and requiring cautious interpretation. The study found a positive causal relationship between T2D and pulmonary tuberculosis (OR = 1.24, 95% CI = 1.05–1.45, p < 0.05). However, they exhibited pleiotropy (p < 0.05), indicating their instability. No correlation between T2D and interstitial lung disease or lung cancer was observed.

Conclusion

T2D is negatively associated with COPD, suggesting that T2D may reduce the risk of developing COPD. A negative causal relationship between T2D and bronchial asthma has been observed, but the results exhibit heterogeneity. There is a positive causal relationship between T2D and pulmonary tuberculosis, yet the findings suggest the presence of pleiotropy. No significant causal relationship between T2D and lung cancer or interstitial lung disease was observed.

Backgrounds

Freezing of gait (FoG) is a common and debilitating symptom of Parkinson's disease (PD) that can lead to falls and reduced quality of life. Wearable sensors have been used to detect FoG, but current methods have limitations in accuracy and practicality. In this paper, we aimed to develop a deep learning model using pressure sensor data from wearable insoles to accurately detect FoG in PD patients.

Methods

We recruited 14 PD patients and collected data from multiple trials of a standardized walking test using the Pedar insole system. We proposed temporal convolutional neural network (TCNN) and applied rigorous data filtering and selective participant inclusion criteria to ensure the integrity of the dataset. We mapped the sensor data to a structured matrix and normalized it for input into our TCNN. We used a train-test split to evaluate the performance of the model.

Results

We found that TCNN model achieved the highest accuracy, precision, sensitivity, specificity, and F1 score for FoG detection compared to other models. The TCNN model also showed good performance in detecting FoG episodes, even in various types of sensor noise situations.

Conclusions

We demonstrated the potential of using wearable pressure sensors and machine learning models for FoG detection in PD patients. The TCNN model showed promising results and could be used in future studies to develop a real-time FoG detection system to improve PD patients' safety and quality of life. Additionally, our noise impact analysis identifies critical sensor locations, suggesting potential for reducing sensor numbers.
