Authors: Kausar Ayesha
Published: July 2024

Among carbon nanoparticles, fullerene has been observed as a unique zero-dimensional hollow molecule. Fullerene has a high surface area and exceptional structural and physical features (optical, electronic, heat, mechanical, and others). Advancements in fullerene have been observed in the form of nanocomposites. Application of fullerene nanocomposites has been found in the membrane sector. This cutting-edge review article basically describes the potential of fullerene nanocomposite membranes for water remediation. Adding fullerene nanoparticles has been found to amend the microstructure and physical features of the nanocomposite membranes in addition to membrane porosity, selectivity, permeation, water flux, desalination, and other significant properties for water remediation. Variations in the designs of fullerene nanocomposites have resulted in greater separations between salts, desired metals, toxic metal ions, microorganisms, etc. Future investigations on ground-breaking fullerene-based membrane materials may overcome several design and performance challenges for advanced applications.

Effects of Azotobacter spp., mycorrhizal fungi and shade treatments on plant growth and chlorophyll content in boxwoods plants
Authors: Sarı Ömer
Published: July 2024

In this study, two important commercial species, Buxus microphilla and B. herlandii, were evaluated. People do not want polluting and toxic fertilizers used to cultivate the plants they use for nutrition, and they do not want the plants they use as ornamental plants. The study investigated the effects of mycorrhizal and bacterial applications on plant growth and chlorophyll content. As a result of the study, it was concluded that bacterial applications on the development of boxwoods are more effective than mycorrhizal applications. Shading further increased the effect of the applications. In B. microphilla, in a 70% shade, plant height increased by 18.5% with mycorrhizal application, and plant width increased by 29.7% with bacterial application. In B. herlandii, bacterial application increased plant height by 13.3% and plant width by 20.4%. In shadowless application, the amount of chlorophyll in B. herlandii leaves was found to increase by 47.20% with bacteria and in B. microphilla, it increased by 65.86. In shadow application in B. herlandii, leaves were found to increase by 76.70% with bacteria; in B. microphilla, it increased by 94.93%. It was concluded that the bacteria application is more effective than others because Azotobacters fix the free nitrogen in the air to the boxwood soil, which needs continuous nitrogen for growth and development. For this reason, N-fixing bacteria applications to the soil can be used as an alternative to chemical fertilizer applications in boxwood cultivation or hedge formation.

Authors: Kowalska Beata , Szczech Magdalena
Published: July 2024

The consumption and sale of ready-to-eat products, i.e., fresh-cut vegetable salads and fruit, have been growing tremendously in the present time. Therefore, the microbial safety of such products is of great concern. In the current study, a survey of general microbiological contamination (mesophilic bacteria, yeasts, molds, Enterobacteriaceae, coli bacteria, Enterococcus, Lactobacillus, and Escherichia coli) of fresh-cut vegetable salads and berry-packed fruits available in Polish supermarket was undertaken.In ready-to-eat salads, the high number of mesophilic bacteria ranged from 6.43 to 8.56 log10 cfu g–1, and also Enterobacteriaceae with mean value from 3.45 to 4.08 log10 cfu g–1 was detected. Mesophilic bacteria, yeast, and Enterobacteriaceae were detected in all salad samples. The molds were detected in 45% of salad samples, and their mean number ranged from 0.63 log10 cfu g–1 in salads with carrot or beetroot to 1.80 log10 cfu g–1 in salads with rocket.Berry fruit was also heavily microbiologically contaminated. In particular, the means of mesophilic bacteria, molds, and yeasts were high. The number of molds detected in fruit samples, especially in raspberry samples, could be alarming. Enterobacteriaceae, Enterococcus, and coli bacteria were detected in a few samples of berry fruit. None of the ready-to-eat salads and fruit samples were contaminated by Escherichia coli.Based on the tests that were conducted, it was found that the microbiological quality was not satisfactory. The findings suggest that following hygienic measures during processing and handling, the microbiological quality of vegetable salads and berry fruit available in Polish markets should be improved.
Research of Casting and Solidification of Steel Ingots by Application of Low-Melting Materials
Authors: Kantoríková E. , Moravec J.
Published: July 2024

The article describes the simulation of the casting of the low-melting material stearin into a mold, which serves as a real simulation basis for monitoring the displacement during the solidification of steel ingots. The physical properties and occurrence of shrinkage are comparable for both liquid stearin and molten steel. In this way, it is possible to easily monitor the solidification of ingots after casting, while the entire simulation takes place at low temperatures, which is experimentally simpler and more practical than trial casting steel at high temperatures. The process is convenient, simple, fast and cheap. The essence is therefore the application of a new perspective on the mentioned process and its transfer into foundry practice. The temperature drop in the entire volume of the sample was monitored from filling the mold to cooling to ambient temperature and the formation of shrinkage, which was monitored and evaluated in the internal body of the ingot. The tests confirmed the suitability of selected material for this method of experimental work because they were able to capture the real behavior of the cast steel in the mold. The method proves to be suitable for industrial applications where similar multidimensional castings are produced.

Published: July 2024

Efforts to miniaturize and customize electronic devices have attracted considerable amounts of attention in many industrial fields. Recently, due to its innovative printing technology with the capability of printing fine features onto non-planar substrates without masks, aerosol jet printing (AJP) is emerging as a promising printed-electronics technology capable of meeting the requirements of various advanced electronic applications. In this research, a novel manufacturing process based on AJP is proposed in order to fabricate highly flexible and conductive customized temperature sensors. To improve the flexibility and conductivity of the printed tracks, a silver nanoparticle/carbon nanotubes composite ink is developed. Customized temperature sensors are then designed and fabricated based on the optimized process parameters of AJP. It was found that the CNTs served as bridges to connect silver nanoparticles and defects, which could be expected to reduce the contact resistivity and enhance the flexibility of the printed sensor.

Published: July 2024

LaYO3 which has phase stability at high temperature is introduced as a promising candidate for reaction-preventing crucible materials with Uranium-Zirconium (U-Zr) melt containing rare-earth elements (RE). RE is composed of rare-earth elements such as Nd, Ce, Pr and La. The LaYO3 material was synthesized by a solid-state reaction method at elevated temperature according to a pseudo-phase diagram of LaYO3 and Y2O3. Green compacts blended with La2O3 and Y2O3 powder were made by the Cold Isostatic Pressing (CIP) method, with La2O3 and Y2O3 powders varying with molar ratios from 1.0 to 1:2. LaYO3 synthetics were fabricated at sintering temperatures ranging from 1450°C to 1600°C. LaYO3 pellets sintered at below 1550°C showed a highly dense orthorhombic phase with a perovskite structure, resulting in an enhancing reaction-resistant effect with RE.

Published: July 2024

Recent advances in artificial intelligence have opened up new avenues for microstructure characterization, notably in metallic materials. Physical and mechanical properties generally depend on the microstructure of the metallic material. On the other hand, microstructural characterization takes time and calls for specific techniques that don’t always lead to conclusive results quickly. To address this issue, this research focuses on the application of artificial intelligence approaches to microstructural categorization. We demonstrate the advantages of the AI approach using an example of Al-Si alloy, a material that is widely employed in a variety of industries. To specify a suitable convolutional neural network (CNN) approach for the microstructural classification of the Al-Si alloy, CNN models were trained and compared using DenseNet201, Inception v3, InceptionResNetV2, ResNet152V2, VGG16, and Xception architectures. Resulting from the comparison, it was determined that the developed supervised transfer learning model can execute the microstructural classification of Al-Si alloy microstructural images. This paper is an attempt to advance methods of microstructure recognition/classification/characterization by using Deep Learning approaches. The significance of the established model is demonstrated and its accordance with the literature data. Also, necessity is shown of developing material models and optimization through systematic microstructural investigation, production conditions, and material attributes.

Published: July 2024

This study demonstrates the development of a unique hybrid thermoplastic composite using reduced Graphene oxide (rGO) content and Zirconia (ZrO2) nanoparticles into the Ultra-High Molecular Weight Polyethylene (UHMWPE) biomaterials for continuous loading conditions. Specimens with different loadings of rGO (0 to 1.5 wt.%) and ZrO2 (5 to 10 wt.%) were fabricated using liquid phase ultrasonication followed by the hot press moulding method. The samples were analyzed using Thermogravimetric Analysis (TGA), Impact (Izod) testing, and Dynamic Mechanical Analysis (DMA). The developed material feasibility was assessed using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDX) analyses. The findings revealed that the 1 wt.% rGO/5 wt.% ZrO2/UHMWPE sample improved the storage modulus by 66.15%, and the Impact absorbed energy by 11.33% compared to the pristine UHMWPE. The proposed nanocomposite could be endorsed for artificial joints, prostheses, and other Artificial Bio-Bearing (ABB) applications.

This study assessed the morphology and chemical composition of coir coconut husk carbon fiber, as well as the impact of fiber diameters on the physical and mechanical properties of polylactic acid composites. Researchers are studying polylactide acid, a biodegradable material. This eco-friendly material’s excellent features, generated from sustainable and renewable sources, have drawn many people. Malaysia’s high coconut fiber output made coir husk a popular commodity. Coconut fibers are lignin, cellulose, and hemicellulose. Alkaline treatment eliminates hemicellulose, oil, wax, and other contaminants from coir fibers and removes lignin. Fourier Transform Infrared Spectroscopy and Scanning Electron Microscopy were used to examine the treated coconut fibers’ chemical modification analysis and morphology. Coconut coir husk was carbonized to produce carbon fiber using a furnace operated at 300°C for 2 hours. Fiber and polylactic acid were mixed in different fiber sizes (0, 53 μm, 75 μm, and 212 μm) via extrusion and injection processing techniques. The results showed that the alkali treatment reduced the hydroxyl (-OH) group and separated the area from the carbonyl (C=O) group of coconut coir husk, which changed the filler’s hydrophilicity. The fiber size of 212 μm was discovered to have the highest tensile and flexural strength values. According to testing, the modified material structure had a better surface fill-matrix bond. Thus, generalized fiber sizing and characterization methods were developed. Regardless of the matrix, this method can characterize natural fiber strength and interfacial shear strength of varied diameters and solid contents.

Authors: Chadha K. , Tian Y. , Spray J.G. , Aranas Jr. C.
Published: July 2024

Microstructure and texture analysis were conducted employing electron backscatter diffraction (EBSD) technique on laser powder bed fusion (LPBF) fabricated pure Ni. The texture analysis of the hot isostatic pressed (HIP) and as-printed (AP) samples were done utilizing orientation distribution function (ODF) maps. The AP sample comprises mostly of <110>||BD fiber texture with insignificant presence of twins. In contrast, the HIP sample has <111>||BD grains. It was found that the development of the texture <111>||BD was due to the deformation linked to the HIP process. In addition, HIP generated a substantial fraction of Σ3 coincident site lattice boundaries (CSL) because of pure Ni which is a medium stacking fault energy (SFE) element.
Czy wiedza leczy demokrację?
Authors: Kaczmarczyk Michał
Published: July 2024

Artykuł dotyczy przemian statusu i funkcji wiedzy w nowoczesnym, zróżnicowanym funkcjonalnie społeczeństwie. W szczególności przedmiotem rozważań autora jest relacja między przemianami wiedzy – jej funkcji i charakteru – oraz tendencjami populistycznymi w polityce ostatnich lat. Autor formułuje trzy hipotezy dotyczące możliwego związku między wiedzą a wzrostem populizmu. Ich podstawą jest bardziej ogólna diagnoza współczesności zaczerpnięta z prac Niklasa Luhmanna i interpretacja pochodzącej od niego koncepcji inkluzji społecznej. Jak wnioskuje autor artykułu, era nowożytna jest areną inkluzji o bezprecedensowej skali, a proces ten zmienia formy dystrybucji wiedzy oraz jej charakter. Wedle jednej z zaprezentowanych hipotez przemiany te wpływać mogą na samorozumienie obywateli i komunikację polityczną.
The Impact of Economic Development on Environmental Pollution in Romania. A Research Based on Kuznets' Environmental Curve
Authors: Gheorghe Maria
Published: July 2024

The current paper aims to study the application of this theory in the current economic context in Romania, contributing to filling the gaps in the existing research on this subject. Thus, in the practical part of the paper, a non-linear regression model was created using the volume of greenhouse gases as the dependent variable (representing environmental degradation) and the GDP per capita as the independent variable (representing the economic development of the country). The results suggest a significant impact of economic development on environmental pollution in Romania between 1990 and 2022. The positive correlation between GDP per capita and greenhouse gas emissions, as indicated by the positive coefficient of DPIB (1), underscores the importance of managing economic growth sustainably to mitigate environmental impacts. This finding aligns with Kuznets' environmental curve theory, which proposes that initially, rising per capita income can result in higher pollution and greenhouse gas emissions as developing nations prioritize economic advancement over environmental concerns. However, as economies progress and mature, there is an opportunity for the adoption of cleaner technologies, the implementation of environmental regulations, and investments in sustainability, potentially leading to a reduction in both greenhouse gas emissions and pollution.

Published: July 2024

The drylands of Africa are experiencing food insecurity due to prolonged drought and water scarcity which has a negative effect on crop production. In the drylands of Sub-Saharan Africa, many small holder farmers are experiencing low crop yields and economic returns as a result of poor soil fertility and water scarcity. This is because of the inappropriate soil and water conservation strategies used in the region. Zai pits have been used as a soil and water conservation strategy in the drylands of Africa in combination with integrated soil fertility management (ISFM) options to improve soil fertility, increase the overall crop yields and the economic returns. This review deals on the role of zai pits and integrated soil fertility management options in improving productivity for the small holder farmers in the drylands of Sub-Saharan Africa. Zai pits have been used to harvest water which ultimately improves soil moisture for crop production with the different fertility inputs applied in the pits for nutrient efficiency. To evaluate productivity and profitability in zai tillage system, yield, benefit cost ratio (BCR) and net benefits are used. In this study, different studies by researchers on the use of zai pits and integrated soil fertility management options have been discussed and this would be beneficial for other researchers who have interest in this field. Most studies have indicated that the zai pit technology is an important soil and water conservation strategy which in combination with the integrated soil fertility management (ISFM) options improves crop productivity in terms of yield and economic returns.

Authors: Aperribay-Bermejo Maite
Published: July 2024

El agua, como cualquier otro recurso natural, es un recurso muy preciado pero a su vez finito. El consumo desmedido y numerosas prácticas agrarias y empresariales, así como los fenómenos meteorológicos extremos están provocando que el agua sea un bien cada vez más escaso y al mismo tiempo más contaminado. Tal y como reconoce la Organización de Naciones Unidas (s. f.), el agua es esencial no solo para la salud sino también para la reducción de la pobreza, la seguridad alimentaria, la paz, los derechos humanos, los ecosistemas y la educación. El agua es básica para la vida, y en ese sentido educar en la importancia del agua –y de la naturaleza en general– es imprescindible. El presente trabajo proporcionará una introducción a la Educación Ecosocial, una educación basada en valores como la justicia social y medioambiental. Asimismo analizarán una serie de obras de la Literatura Infantil y Juvenil, lecturas que proporcionarán un marco inmejorable para trabajar conjuntamente la educación literaria y la educación ecosocial. El respeto al medioambiente, la defensa de la igualdad o el reconocimiento del valor de la diversidad lingüística y cultural centrarán los análisis, que serán complementados mediante propuestas de acciones que capaciten al alumnado para ser agentes de cambio social.

Published: July 2024

The bacteria Staphylococcus aureus, a normal component of human flora, is easily mutated and antibiotic-resistant, leading to the creation of Methicillin-Resistant Staphylococcus aureus (MRSA). This bacterium is a difficult-to-control nosocomial infection in healthcare settings, so it must be stored using specialized preservation agents, like DMSO, to investigate the nature and characteristics of these bacteria for prevention, control, and therapy. The purpose of this study was to evaluate the survival of MRSA bacteria that had been kept in a DMSO solution at various temperatures and periods. This study was carried out between July and October2022 using a one-shot study case research design, data analysis, and quantitative descriptive analysis. According to the findings, MRSA bacteria held in 15% DMSO solution lost viability over time and at various storage temperatures. Among various bacterial species held at various storage temperatures, MRSA bacteria had the lowest colony loss rate (-20 °C). Based on the findings of this study, it can be said that the preservation of MRSA bacteria at freezing temperature (-20 °C) and storage length of one month resulted in the greatest survivability of the bacteria when stored in 15% DMSO solution.
Clean energy in Latin America: the case of Mexico
Authors: Bochkova Angelina Aleksandrovna
Published: July 2024

The subject of the study is clean energy in Latin American countries, the object of the study is renewable energy sources in Mexico. The purpose of the study is to determine the role of renewable energy sources in the economic development of Latin American countries using the example of Mexico. The author examines in detail such aspects of the topic as the development of alternative energy sources in Mexico, its impact on the country's GDP growth rate; factors affecting the production of clean energy in Latin America on the example of Mexico. Special attention is paid to the opportunities that open up to the country due to the active transformation of the Mexican energy complex. In addition, the author examines alternative energy sources and their impact on the economic development of the Latin American region using the example of Mexico. In order to achieve this goal, general scientific methods of systematic and comparative analysis, the method of generalization, methods of grouping and classifying quantitative and qualitative data, methods of quantitative data analysis were used. The main conclusions of the study are that today the production of renewable energy sources has little effect on the volume of the Mexican economy, but there is an active development of clean energy sources in Mexico, and in general, throughout the Latin American region. This is proved by the econometric model constructed by the author. The model shows which source of clean energy is developing at the fastest pace and which sources account for the bulk of production. The novelty of the study lies in the fact that the author analyzes how the development of alternative energy sources in Mexico affects the country's GDP growth rate. In addition, the study identified an alternative energy source that has a greater impact on the economic development of the country, as well as identified factors affecting the production of clean energy in Latin American countries, using the example of Mexico.
Y-chromosomal ancestors: on the problem of genetic and genealogical nomination
Authors: Nilogov Aleksei Sergeevich
Published: July 2024

The article deals with the problem of the nomination of patrilineal contiguities determined on the basis of genome-wide sequencing of the male sexual Y chromosome. As a result of the detection of irreversible mutations (single nucleotide polymorphisms), it becomes possible to name our distant ancestors using SNP marker indices. Having previously justified the method of "sniping as naming", we have increased the nominative retrospective on the reconstruction of phylogenetic and genealogical lines. Thanks to the use of index names of Y-chromosomal mutations, it was possible to indirectly fill in the proper names of those neighbors who lived earlier in the preserved archival and documentary fund of genealogical sources. We are talking about onomatization as a process of resurrecting the names of ancestors whose genetic traces appeared in our Y chromosomes in the form of snip mutations, in fact attributing a specific male progenitor, who for the first time had an irreversible neutral ONP. The DNA molecule, like a biological document, contains information about our origin hundreds of thousands of years deep, being a genetic cemetery of lucky ancestors. The more human Y chromosomes are sequenced, the more names of proper male ancestors will be reconstructed on the Y-haplodreve. Despite the fact that the nomenclature of SNPs is constantly changing, including due to the synonymization of designations depending on developers and laboratories, the fact of nominative reconstruction of our phylogenetic neighbors through large-scale genome-wide sequencing remains immutable. On the example of the genetic-genealogical (genealogical) reconstruction of the author's patrilineal line, the prospects of a comprehensive (interdisciplinary) study of human patrilineal kinship are shown.
Union of Writers of Khakassia 1992-1998. The role of personality
Authors: Akhremchik Olga Gennadyevna
Published: July 2024

The oldest and most authoritative creative union in the Republic of Khakassia is the Union of Writers. In the 1990s, the system of organizing the economic life of the writers' organization was destroyed, and the work of the association during this period was dictated by the need to preserve the experience of organizational work accumulated in Soviet times, to find new mechanisms for further existence and creative development. The subject of the study is the activity of N.M. Akhpasheva as chairman of the Union of Writers of Khakassia (1992–1998). She was able to maintain the capacity and authority of the creative association. The object of the study is the Union of Writers of Khakassia as a creative association that has a direct impact on the development of culture of the Republic of Khakassia. Special attention is paid in the study to the mechanism of activity of the regional writers' department and the influence of the personality of the chairman, N. M. Akhpasheva, on it. In the process of work, special historical research methods were used: problem-chronological, historical-genetic, historical-comparative, historical-systemic. The narrative method (sometimes called descriptive-narrative) was used for a coherent presentation of documents examined in the archives about the activities of N.M. Akhpasheva and the Writers' Union. For the first time, the paper attempts to analyze the peculiarities of the relationship between the chairman of the Union of Writers of Khakassia N.M. Akhpasheva and colleagues within the creative union, its relationship with the authorities and society of the Republic of Khakassia in the period 1991–2021. The scientific novelty lies in the study of creative guidelines in the most influential creative association of the selected period. The author pays attention to the contribution of the chairman of the creative organization N.M. Akhpasheva to the development of national and regional culture. When analyzing archival documents of this period, the directions of activity are traced, new approaches in organizing the activities of writers are identified, and the conclusion is made about the importance of the role of the creative association and its chairman in the culture of the republic of this period. All this gives us the right to present a general panorama of the activity of the chairman and the creative union, the role of individual representatives in the cultural and historical life of the Republic of Khakassia during the selected period, as well as in clarifying the main forms of activity of the association.
Positive and negative paradigms of personal functioning and development in the pre-retirement and retirement ages
Authors: Budyakova Tatyana Petrovna , Pronina Angelika Nikolaevna
Published: July 2024

The presented article is devoted to the problem of identifying and describing life paradigms in old age. The theoretical part shows the advantages of the paradigmatic approach in gerontopsychological research. The value of its variability is emphasized, when paradigms can be changed, modified or evaluated in accordance with established personal meanings and values. The theoretical part also analyzes the existing models of life paradigms in late ontogenesis. Special attention is paid to paradigms that include a victimological context. It is shown that foreign paradigms, in particular, the paradigms of yoga and the "American dream" cannot be successfully implemented into Russian culture due to value contradictions. It is noted that the least studied element of life paradigms are the principles of life, which have become the subject of study in the empirical part of the study. Biographical, autobiographical and meaningful content analysis were used as research methods. The material of the analysis was the content of forums on the Internet dedicated to the problems of the elderly, the participants of which were pre-retirees and pensioners. The scientific novelty of the study consists in identifying and describing the basic and particular life principles that make up the positive and negative paradigms in later life. Thus, such general principles as concreteness, anticipativeness, variability, priority, anxiety, vulnerability, responsibility, forgiveness, etc. were formulated. It is concluded that the positive paradigm in old age is an anti–victim paradigm, that is, a behavior model based on the anti-victim Self-concept that ensures the safety of the individual in old age, and an ineffective one is victimized, contributing to the transformation of an elderly person into a victim of circumstances, primarily subjective. Life paradigms in old age should change with changes in living conditions and health conditions. The paradigmatic principles differ depending on gender.
Phonetic Adaptation as a Way of Incorporating Borrowed Legal Terms in the Yakut and Kyrgyz Languages
Authors: Гаврильев С.Л.
Published: July 2024

Фонетическая адаптация как способ инкорпорации иноязычной лексики ранее не являлась предметом изучения в якутской юридической терминологии, также в данном направлении не проводились исследования в ракурсе лингвистической компаративистики. Выбор якутского и киргизского языков для сравнения обусловлен генетической близостью языков, схожестью отдельных этапов исторического развития народов, возможностью обоюдного заимствования теоретических и практических разработок. Целью исследования является описание отличий и универсалий в адаптивных инструментах в синхронии и диахронии. Для достижения этой цели ставятся задачи выявления, анализа и классификации закономерностей и способов трансформации заимствованных юридических терминов. Фактический материал для исследования отобран методом сплошной выборки. Источниками стали законодательные акты, отраслевые, переводные, орфографические словари якутского и киргизского языков. При анализе материала использованы описательный метод, методы обобщения, аналогии, статистического подсчета, компонентного, сравнительно-исторического, фонетического анализов. Особенности исторического развития народов обусловили наличие большого количества заимствований из русского языка в якутской терминологии и из арабского, персидского, русского языков в киргизском. В более ранний период при устном заимствовании ассимиляция терминов происходила естественным образом по мере их поступления. Именно в этот период возникли общие закономерности трансформации заимствований, подчинения их фонетическим нормам языков-реципиентов. Для советского периода развития якутской и киргизской терминологии характерным является искусственная адаптация заимствований, которая во многом базировалась на ранее выработанных принципах «естественной» терминологии. В современный период в условиях двуязычия фонетическая адаптация теряет свою привлекательность и продуктивность. В ходе настоящего исследования выявлены, классифицированы и описаны наиболее характерные для якутского и киргизского языков виды фонетической адаптации.
