Published: December 2023

The strategy to reduce the high infant mortality rate (IMR) is by placing midwives in the village. One of the tasks of village midwives is the prevention of complications through early detection, which is indicated by the performance of midwives based on neonatal coverage. Situation awareness is an important component of decision making that has a significant impact on the performance of the village midwife's duties, so the purpose of this study was to analyze the effect of the role of situation awareness on the performance of the village midwife's duties in detecting problems in young infants. Quantitative research was designed using a cross sectional study. All village midwives became the population and were determined based on the results of a sample calculation of 151 village midwives who would be taken proportionally. The research variables were situation awareness and task performance. The instrument used a questionnaire and analyzed using Simple Linear Regression. The results explained that the consistent value of task performance was 43.041. B situation awareness value (regression coefficient) 0.917. The regression coefficient is positive that the direction of the influence of situation awareness on task performance is positive. Decision making in simple linear regression is 0.000 <0.05 with the t value showing 8.256> from the t table of 1.97, which means that situation awareness has an influence on the performance of the village midwife's duties.  Situation awareness is a predictor that is able to influence task performance for village midwives in providing care to neonates in early detection of problems in young infants.

Waiting time significantly associated with facility.
An Optimality-Theoretic analysis of stress in the Bani Sulaim dialect
Authors: Al Solami Majed
Published: December 2023

This study presents an Optimality-Theoretic analysis of stress assignment in a Bedouin Hijazi Arabic dialect. The proposed analysis includes several constraints, among which are NONFIN, which disallows stress word-finally, FBIN, which requires words to be minimally bimoraic, IAMBIC, which requires feet to be right headed, and WSP, which stipulates that heavy syllables are stressed. Importantly, the ranking relations between these constraints solve certain issues found in previous rule-based accounts of the dialect, namely accounting for trochaic stress in disyllabic words and stress in words with final heavy syllables. Trochaic stress in previous studies was seen to result from the interaction between extrametricality and foot binarity requirements, where final syllable extrametricality is revoked only in disyllabic words in favor of satisfying foot bimoraic weight. Words with final stress, on the other hand, were not accounted for in previous studies. The current study shows that Optimality Theory adequately accounts for trochaic stress and words with a final heavy syllable.
A contrastive analysis of aspect in English and Moroccan Arabic
Authors: Boubekri Abdelhakim , Ech-Charfi Ahmed
Published: December 2023

This study endeavors to undertake a comparative analysis of aspect in English and Moroccan Arabic, hereafter referred to as MA, adopting a cognitive linguistic approach, with special attention to the categorization of different situation types as proposed by Radden and Dirven (2007). It also aims to highlight the aspect areas that may challenge Moroccan EFL learners when acquiring this English grammatical construction. The study reveals that aspect is treated differently in English and MA. English aspect hinges on the viewing frame adopted. Therefore, the shift from one viewing frame to another results in the change from one situation type to another. By contrast, in MA, the perfective use calls for the adoption of a maximal viewing frame. However, the imperfective use calls for two interpretations: the event can be seen with either a maximal or a restricted viewing frame. In the absence of elements that co-determine the aspect in MA, general context is the only indication of the appropriate interpretation. The differences in the aspectual systems of English and MA may lead to difficulties in language acquisition. MA learners attempting to learn English, and vice versa, may face challenges in learning both the grammatical structure and its associated meanings.
Między radością a smutkiem. O nadziei w poezji Nikołaja Karamzina
Authors: Dąbrowska Magdalena
Published: December 2023

The paper presents the poems by Nikolay Karamzin (1766–1826), which refer to hope. They include the following groups of texts: 1) reflection poems: To myself (1795), The song (1795), The hope (1796), To an unfaithful (1796), Sorrow and joy (1797), The coast (1802); 2) occasional poems: about the Tsar Pavel I (1796), about G. Khovanski (1796) and about P. Pelski (1803); 3) poems touching upon the life of a poet and poetry: To a poor poet (1796) and The talents (1796). Some poems are autobiographical (The coast was written after the death of Karamzin’s first wife). The hope, which is based on a comparison of a human’s life to a journey, is considered the most meaningful of his texts. According to Karamzin, life is filled with joy and sorrow, expectation and disappointment, but hope makes the plans easier to achieve, and brings a man closer to the goal. The meaning of his poems is optimistic after all. Karamzin’s letters to Ivan Dmitriev, a poet and a friend, serve as an interpretive background in the article.
Leksykalne wykładniki emocji pozytywnych w tekście polskim w porównaniu z rosyjskim przekładem
Authors: Rudyk Anna
Published: December 2023

This article analyses Polish nouns denoting selected positive emotional states in comparison to their equivalents in the Russian text. The factual material was taken from Katarzyna Kołczewska’s book entitled Kto, jak nie ja? and its translation into Russian, and includes sentences containing the above-mentioned nouns and their equivalents from the target text. The conducted analysis allows us to state that the nouns denoting emotions recorded in translation dictionaries, despite the presence of exact equivalents, are translated by means of lexemes modifying their meaning both in the quantitative aspect (by using lexemes indicating emotional states of higher or lower intensity), as well as in the qualitative aspect. In addition, the emotional meaning of selected nouns is conveyed in the target text by means of words referring to other parts of speech, often co-occurring with the main dictionary equivalent. The study has shown that despite the presence of established equivalents in translation dictionaries, the meaning of nouns naming selected positive emotions is conveyed in different ways in the Russian translation text. The presented repertoire of textual equivalents is by no means complete and final. The study concludes that the repertoire remains open, and textual realizations are not always consistent with the equivalents proposed by the dictionary.
Moral Reorientation through the Emulation of Christ in the Teachings of Joseph Ratzinger – Pope Benedict XVI
Authors: Kluz Marek
Published: December 2023

The aim of this publication is to outline a moral reorientation through the emulation of Christ based on the teachings of Josef Ratzinger – Benedict XVI. The study used the method of source analysis and synthesis of the researched content, which provided an insight into the fundamental thoughts of Joseph Ratzinger – Benedict XVI. In a contemporary society which is undergoing dehumanisation, individuals who are receptive to values can often become disoriented and struggle to find their rightful place in the world. Therefore the moral state of modern humanity requires a fundamental change. An individual capable of providing healing to human beings challenged in their development, and reinstating a sense of purpose to their existence on Earth is needed. Responding to the demands of the modern era, Pope Benedict XVI identifi ed Christ as the cornerstone for the conversion of human hearts and minds. The relationship with Christ, which is central to the concept of emulation, is essential for being a genuine Christian. Emulating Christ within the temporal continuum of a Christian’s life necessitates addressing personal problems and the surrounding reality through the lens of the Gospel’s principles.

Monitoring drought dynamics using remote sensing-based combined drought index in Ergene Basin, Türkiye
Authors: Gümüş Kerim Aykut , Balçık Filiz Bektaş , Esetlili Tolga , Kahya Ceyhan
Published: December 2023

Remote sensing-based approaches have gained widespread usage in drought monitoring studies. However, relying on single-variable drought indices may be inadequate to provide a comprehensive understanding of drought dynamics. In this study, principal component analysis was employed to derive a combined index, namely, the combined drought index (CDI), from multiple indices such as vegetation condition index, temperature condition index, precipitation condition index, and soil moisture condition index. The CDI was subsequently employed to analyze drought occurrences in the Ergene Basin-Türkiye period from 2001 to 2020 (May to October) using MODIS data. Correlations were computed with standardized precipitation index (SPI) and standardized precipitation evapotranspiration index (SPEI) at 1-, 3-, and 6-month scales and crop yield. The results revealed that drought incidents transpired in the Ergene Basin for at least 1 month annually. May exhibited the wettest, while September stood as the driest month. The severity of drought and its spatial extent displayed an increasing trend followed by a subsequent decline during the aforementioned period. The CDI demonstrated stronger correlations with the 1-month standardized indices than the 3- and 6-month SPI-SPEI. A robust correlation of 0.79 was also observed between the CDI and the crop yield. In general, the CDI performed well in determining the spatial and temporal patterns of the historic droughts. As a result, the CDI could be leveraged to develop effective drought monitoring and management, which could help mitigate the negative impact of drought in the fragile environment of the Ergene Basin.

Background

The field of nanomedicine has attracted much interest and is now serving as the impetus for many revolutionary advances in the pharmaceutical industry.

Objectives

In the current exploration, we intended to fabricate the zinc/sodium alginate/polyethylene glycol/d-pinitol nanocomposites (ZSP/D-Pin/NCs) and evaluate their antimicrobial and anticancer properties against MG-63 cells.

Methods

ZSP/D-Pin/NCs were synthesized and characterized using several techniques and their cytotoxicity was examined against osteosarcoma MG-63 cells and normal 3T3 cells using the MTT assay. The levels of oxidative stress and apoptotic protein were examined using assay kits and fluorescence staining.

Results and Conclusion

The findings of several characterization studies revealed the development of agglomerated and crystalline ZSP/D-Pin/NCs. The antimicrobial assay demonstrated that ZSP/D-Pin/NCs substantially inhibited the growth of pathogens. Additionally, the MG-63 cell viability, which was exposed to several doses (1–20 µg) of ZSP/D-Pin/NCs, showed a remarkable decrease at various time periods, i.e., 24, 48, and 72 h without showing toxicity in 3T3 cells. The results of the fluorescence staining assay demonstrated that ZSP/D-Pin/NCs considerably increased apoptosis in the MG-63 cells by triggering oxidative stress. The antioxidants were reduced and upregulated the Bax and caspase expressions in ZSP/D-Pin/NC-treated MG-63 cells.

Authors: Qiao Meiying , Yao Wenhao , Gao Kefei , Du Heng , Zhao Kaidong
Published: December 2023

This paper presents a new method for in-field calibration of accelerometers to address the problems of low efficiency and high cost associated with traditional calibration methods. A nonlinear mathematical model of the accelerometer is established, and the cost function is analysed and deduced the cost function. Then, an adaptive Northern Goshawk Optimisation (NGO) algorithm based on prior knowledge enhancement is introduced. A method of collecting multi-position data with a hand-held accelerometer is introduced, and the proposed algorithm is used to in-field calibrate nine parameters of the accelerometer’s nonlinear error model. In addition, simulation is used to compare the results of calibrating the accelerometer using the proposed algorithm and the original algorithm, demonstrating the superiority of the proposed algorithm. Finally, experimental results confirm that the proposed method can rapidly calibrate accelerometer error parameters without relying on complex equipment and with greater accuracy than traditional methods.

Izražavanje emocije sreće u hrvatskim i talijanskim frazemima
Authors: Mušac Vini
Published: December 2023

U ovome radu istražit će se način izražavanja sreće u hrvatskoj i talijanskoj frazeologiji i utvrditi postoje li podudarnosti u dvama jezicima s obzirom na plan izraza i na pozadinsku sliku frazema. S jedne strane frazeološka će raščlamba biti osnovana na frazemima čija je jedna od sastavnica sreća (biti lud od sreće) i tal. gioia (essere pazzo di gioia) i njezini sinonimi ili djelomični sinonimi kao što su radost, veselje, fortuna i sl. u hrvatskome, odnosno felicità, allegria, fortuna i sl. u talijanskome te leksemi čije značenje upućuje na druge emocije povezane sa srećom kao što su zadovoljstvo, tal. contentezza. S druge strane analiza će se temeljiti na somatskim frazemima iz čijega se značenjskoga plana iščitava emocija sreće (imati osmijeh od uha do uha i  avere un sorriso da un orecchio all'altro). S treće strane analiza će se temeljiti na nesomatskim frazemima čija pozadinska slika upućuje na emociju sreće (biti u sedmome (devetome) nebu i essere al settimo cielo). U radu se pokazuje da se frazeološki korpus dvaju jezika u velikoj mjeri podudara na planu izraza i sadržaja, ali i da svaki od korpusa sadrži specifičnosti koji su odraz kulture, nataloženoga zajedničkog narodnog iskustva i pogleda na svijet.
Applying Harm Reduction Principles to the Work of Social Workers and “Equal – Equal” Peer Counsellors
Authors: Butvilas Tomas , Petuškaitė Aistė , Žibėnienė Gintautė , Bubnys Remigijus
Published: December 2023

This article presents a study on individuals who provide harm reduction services following the “Equal – Equal” principle – “Equal – Equal” consultants. Their activities are not regulated or extensively studied in Lithuania, but they are being implemented in practice. Both at the scientific and practical levels, there is a discussion about the effectiveness of “Equal – Equal” interventions, so it is likely that services provided on the “Equal – Equal” principle will be integrated into the system of assistance for individuals using psychoactive substances in the future. The study aimed to reveal how “Equal – Equal” consultants and one of the “traditional” harm reduction service providers – social workers – apply harm reduction principles when providing services to individuals using psychoactive substances.
During the study, the “Equal – Equal” principle was revealed, harm reduction principles were identified, and the main similarities and differences in the application of harm reduction principles between professional service providers – social workers and “Equal – Equal” consultants were determined. The qualitative study found that collaboration with communities using psychoactive substances is not typical for the activities of social workers. This group is more inclined to focus on client abstinence, and there is a related moral judgment of the client. Social workers apply the principle of collaboration with the client on a broader scale than “Equal – Equal” consultants. The application of the autonomy principle in social work is complicated by the “double mandate dilemma.” “Equal – Equal” consultants view psychoactive substance use in a very pragmatic way, emphasizing problem-solving strategies based on humanism. Both groups prioritize client life and health protection, rely on an individual approach to the client, and experience difficulties due to emotionally driven desires to influence client decisions.

Published: December 2023

High rearing densities (kg of fish per rearing unit volume) can impact fish health and growth. This study evaluated the stress levels (as indicated by blood glucose) and growth of juvenile Shasta strain rainbow trout (Oncorhynchus mykiss) reared at three densities in 1.8-m diameter circular tanks for 111 days. Initial and final rearing densities for each treatment were: low (4.48 and 47.56 kg/m3), medium (5.96 and 60.60 kg/m3), and high (7.49 and 72.42 kg/m3). Throughout the experiment, blood glucose levels from individual fish were not significantly different among the three density treatments. At the end of the experiment, total tank weights and gain were significantly greater in the high-density treatment than the medium-density treatment, which in turn was significantly greater than the low-density treatment. However, percent gain was significantly greater in the low-density treatment. Feed conversion ratio was significantly lower in the high-density treatment compared to the low-density treatment, with the ratio in the medium-density treatment similar to the other two treatments. The results of this study indicate that higher rearing densities do not negatively impact juvenile Shasta strain rainbow trout stress or hatchery rearing performance.

Authors: Kaur Harveen
Published: December 2023

Cough, dyspnea, and chest pain are some of the clinical signs of giant bullae, while in some cases it may be asymptomatic. A pneumothorax can be difficult to identify from giant bullae. A middle-aged patient who had a persistent cough and increasing dyspnea with exertion arrived to the emergency room (ED). A right tension pneumothorax was anticipated based on clinical examination findings, however chest radiography, followed by a contrast-enhanced CT (CECT) scan of the chest showed that the right and left hemithorax were both occupied with giant bullae. Pulmonary tuberculosis (PTB) was diagnosed with sputum for acid-fast bacilli analysis and cartridge based nucleic acid amplification testing (CBNAAT). He was started on antituberculous therapy (ATT) and bullectomy was scheduled for TB-related giant pulmonary bullae.

Published: December 2023

Glyphosate, which has been documented as a contaminant in tea, promotes the proliferation of human breast cancer cells (MCF-7). Tea, on the other hand, includes various antioxidants, including epigallocatechin gallate (EGCG), which may protect against cancer cell proliferation. The purpose of this research is to determine the preventive effect of concentrated brewed green tea on MCF-7 development caused by glyphosate. The glyphosate concentration that promotes MCF-7 development was determined using a serial concentration of glyphosate. Glyphosate concentrations of up to 64 mg/L were shown to have no effect on MCF-7 cell proliferation. Concentrated brewed tea and EGCG 200 mg/L have the potential to suppress MCF-7 cell proliferation in the presence of glyphosate up to 512 mg/L. The combination of glyphosate and concentrated brewed tea or EGCG protects against glyphosate toxicity via altering the expression of tumor suppressor protein (p53).

Published: December 2023

Soil bacteria from tropical environments play a significant role in resolving various environmental issues, including biodegradation. Exploratory research on biodiversity is crucial to develop and harness the potential of different types of soil bacteria that are highly abundant. The bacterial diversity in landfills is typically high due to the decomposition of organic and inorganic waste, creating a favorable medium for the growth and development of soil bacteria. This study aims to assess the candidates of xenobiotic degrading indigenous bacteria from the Probolinggo City landfill using Next Generation Sequencing (NGS) method. The research stages include: 1) sampling, 2) isolation of genomic DNA from samples using the ZymoBIOMICS DNA MiniPrep Kit from Zymo Research, 3) amplification of isolated DNA with primers 16S 27F – 1429R, 4) sequencing the results of DNA amplification with NGS, 5) downstream analysis of the results using software Pavian Krona Tools, and 6) narrative analysis review to identify the candidates of xenobiotic degrading indigenous bacteria. The results show that soil samples from the Probolinggo City landfill exhibited a high diversity of bacterial communities. Based on NGS analysis, 2400 bacterial species were identified, comprising 56 genera, 17 orders, 4 classes, and 4 phyla, with respective abundances of Proteobacteria (70%), Firmicutes (15%), Planctomycetes (2%), and Cyanobacteria (0,3%). Based on the narrative analysis review, several bacteria in the Probolinggo City landfill exhibited potential as: 1) polypropylene-degrading bacteria, including Bacillus cereus, B. licheniformis and B. thuringiensis. 2) styrofoam degrading bacteria, namely Bacillus amyloliquefaciens, Bacillus cereus, Bacillus firmus and Pseudomonas aeruginosa. 3) total ammonia nitrogen (TAN) reducing bacteria, including Bacillus megaterium. 4) pesticide degrading bacteria Profenofos and Chlorantraniliprole, including Bacillus stearothermophilus. and 5) tannic acid degrading bacteria, including Pantoea dispersa. These results indicate that the Probolinggo City landfill is a good habitat for various xenobiotic-degrading bacteria, then the isolation of specific bacteria can be designed using an appropriate selective medium.

Authors: Firdayani Firdayani , Listiana Shelvi , Witanto Billy
Published: December 2023

Emodin (6-methyl-1,3,8-trihydroxyanthraquinone) is a natural anthraquinone derivative with potential pharmacological such as cytotoxic effects. The structure modification could be performed to determine the functional groups that have the role of substance activities. In this study, we modified one hydroxy group in the emodin structure to become dimethyl carbamoyl moiety. Emodin was reacted with dimethyl carbamoyl chloride and potassium carbonate to create 3-dimethyl carbamoyl emodin. The structure of the product was elucidated using mass spectrophotometer (MS), Fourier transform infrared (FTIR), proton and carbon nuclear magnetic resonance (H-NMR and C-NMR). These substances were tested for cytotoxicity against HepG2 cell lines using the MTT assay. According to the evaluation, 3-dimethyl carbamoyl emodin is less cytotoxic than emodin. As a result, the hydroxy group at the C3 position of emodin has been identified as a functional component that contributes to its cytotoxic effect.
The Potential Effect of Honey-derived D-Allulose in Counteracting Hyperglycemia by Time and Dose Dependent Manner in Diabetes Mellitus
Authors: Sari Flori R.
Published: December 2023

Diabetes mellitus has become a worldwide burden due to its persistent, chronic hyperglycemia. D-allulose, a monosaccharide sugar with a 180.16 molecular weight, is widely used as a low-calorie sweetener, is not involved in glucose-related metabolism, and thus does not alter insulin and pancreatic function. This study aimed to evaluate the potential role of honey-derived D-allulose in acute and sub-chronic diabetes mellitus. Diabetic Sprague-Dawley rats were divided into 9 groups and treated with 0.1, 0.2, and 0.4 g/kg BW honey-derived D-allulose for 28, 56, and 84 days. Post-prandial blood glucose levels and body weight were measured every 4 weeks. Significant reductions in post-prandial blood glucose levels were observed on days 56 and 84 treatment with 0.1 g/kg BW D-allulose. More significant reductions were observed on days 28, 56, and 84 of treatment with 0.2 or 0.4 g/kg BW D-allulose. Eighty-four days of treatment with 0.4 g/kg BW D-allulose significantly reduced post-prandial blood glucose levels compared to all groups. We identified that honey-derived D-allulose reduced post-prandial blood glucose levels in a dose- and time-dependent manner. Thus, honey-derived D-allulose may provide beneficial support for diabetic conditions not only as a sweetener but also as a pharmacological treatment.

Published: December 2023

In the pursuit of environmentally responsible chemical processes, we conducted a thorough assessment of the green metrics associated with the Cannizzaro reaction using p-anisaldehyde and benzaldehyde under solvent-free conditions. This research elaborates the application of two different methods i.e., reflux and ultrasonication, applying potassium hydroxide (KOH) as the reagent. The progress of the Cannizzaro reaction was methodically followed via thin-layer chromatography (TLC), and the resulting products were characterized using various techniques, including melting point analysis, Fourier-transform infrared spectroscopy (FTIR), and gas chromatography-mass spectrometry (GC/MS). To measure the environmental impact and sustainability of these reactions, a multifaceted approach was used. Green metrics were evaluated by the state-of-the-art Environmental Assessment Tool for Organic Syntheses (EATOS) software, combined with the Andraos algorithm. Moreover, energy consumption calculations were evaluated. Reasonable analysis of the green metrics results was undertaken in the framework of prevailing literature, permitting to measure the level of eco-friendliness attained. Experimental findings revealed optimal conditions for the Cannizzaro reaction concerning p-anisaldehyde at a temperature of 50 °C for 90 minutes, resulting in remarkable of p-anisyl alcohol and p-anisic acid in 95.16% and 95.04% yields, respectively. Likewise, the reaction involving benzaldehyde reached its peak performance at 50 °C for 2 hours, giving benzyl alcohol and benzoic acid in 96.17% and 97.22% yields, respectively.

The objective of the current study was to evaluate the effect of lactation on oocyte quality and in vitro embryo production in Gyr (Bos indicus) cows. A total of 187 multiparous cows (92 lactating and 95 non-lactating) were subjected to a single session of follicular aspiration. Follicle puncture was performed on a random day of the estrous cycle, without prior application of hormonal drugs. The reco­vered oocytes were subjected to maturation, fertilisation, and in vitro culture. The results indicated that in lactating Gyr cows had the following values of studied variables: number of follicles visualised (22.1±11.38), number of recovered oocytes (17.4±10.21), number of grade III oocytes (7.0±5.86), rate of viable oocytes (72.1±13.11%), number of blastocysts D7 (2.5±2.26) and blastocyst rate (18.3±15.61%), in relation to non-lactating cows (27.7±11.53; 21.1±10.06; 9.8±6.08, 77.4±10.08%; 4.9±3.34; 30.2±15.41%, respectively). In conclusion, the lactation period in Gyr cows affects the performance of in vitro embryo production programmes.

The aim of this study was to detect illegal adulteration of beef meat products with meat from other species. Samples (n=120) of industrial and handmade beef products were randomly collected from retail outlets in Assiut city, Egypt: raw beef burger, oriental beef sausage, beef kofta, and beef luncheon (30 samples each). Samples were analysed using agar gel immunodiffusion (AGID) and modified AGID (MAGID) assays. Results showed that 17.5% of examined products were adulterated with chicken meat. MAGID detected that 14.1% of samples were adulterated with donkey meat, whereas all AGID results were negative. Human tissue was detected in 8.3% (AGID) and 10% (MAGID) of examined samples. Histological examination was then used to detect foreign tissue, and all categories of products were found to be adulterated, and some of them - contaminated with human blood cells. Polymerase chain reaction analysis confirmed that MAGID was more accurate and sensitive than AGID, especially for false negative AGID results. Consumers are advised not to consume too much of the studied meat products to avoid exposure to adulterated or contaminated products that might constitute a health hazard.

Published: December 2023

In the mid-1990s, a copper dagger of the Cucuteni-Vădastra type was found in the Lublin-Volhynian culture cemetery at Strzyżów, south-eastern Poland. The dagger was customized as a pendant and deposited in an inhumation burial that contained the remains of an adult male and over ten other grave offerings dating to the 2nd quarter of the 4th millennium BC. This paper presents the results of archaeological and metallographic examinations of the dagger from Strzyżów and relates them to a wider cultural context of the region. The results of our study show that the dagger has no signs of use-wear, and furthermore indicate that the metal used for its production is fahlore copper which could have been sourced from the Slovak Ore Mountains. The two other Cucuteni-Vădastra type daggers that were discovered in the vicinity of Strzyżów mark the Western Volhynian Upland as a distinct cluster of the Cucuteni-Vădastra dagger industry in Europe. Furthermore, the daggers from Poland evidence a close relationship between the Lublin-Volhynian culture and the Cucuteni-Tripillia complex and attest to the intercultural landscape of the Eastern Carpathians region during the Eneolithic

The barrow site in Zbudza is located in the East Slovak Lowland. In 1980, Elena Miroššayová carried out excavations on the burial mound (no. 1) located behind th old Jewish cemetery. The central burial pit and clusters of pottery and traces of hearths were discovered. Some potsherds the possess ornamentation typical for the Corded Ware culture. The charcoal found near the burial pit were radiocarbon dated to 4140±35 BP (Poz-151727), which can be correlated to the years 2866–2632 BC. At the site in Zbudza and the neighbouring Trnava pri Laborci, thanks to the LIDAR data, about 20 burial mounds in various states of preservation and different chronological positions were registered. Some of them should be associated with the presence of the Corded Ware and Yamna cultures from the 3rd millennium BC. Geophysical prospection of burial no. 2 located in the part of the village called “Imrička” was conducted in 2021.
Developing the optimal chemical composition of heat-resistant Cr-Ni steel for aerospace equipment
Authors: Mishchenko Valeriy , Kripak Alona , Tonkonoh Dmytro
Published: December 2023

The object of research in this work is the processes of forming the microstructure and mechanical properties of heat-resistant steels depending on their chemical composition.
The microstructure and high-temperature mechanical properties of austenitic heat-resistant chrome-nickel steels of the proposed chemical composition were investigated in the work. The microstructure study determined the grain size and topography of inclusions in steels. Based on the results of mechanical tests, a multifactorial experiment was planned, which made it possible to establish the relationship between the mechanical properties of steels with alloying elements selected as factors. The obtained regression equations were used to estimate the quantitative influence of each alloying element on the corresponding mechanical properties.
Analysis of the results of the experiment made it possible to determine the optimal chemical composition of steel for gas turbine engines used in the aerospace industry, as well as in the metallurgy of titanium production.
It is shown that the state of solid solution and heat-resistant niobium and molybdenum carbides (chromium carbides dissolve at a temperature of 950 °C) are an important factor that significantly affects the structure, mechanical, and service properties of heat-resistant steel. The austenite structure is provided by the required amount of nickel.
The resulting indicators of heat resistance of steels of different compositions, tested at temperatures of 850 °C, 950 °C, and 1050 °C, proved the superiority of steel with a higher content of carbon and chromium and a lower content of nickel.
The mechanism of steel strengthening and the influence of alloying with carbon, chromium, and nickel on it have been determined. The optimal chemical composition of heat-resistant steel on an iron-nickel basis for operation at a temperature of 950 °C has been established

The object of the study is the automotive industry of the Republic of Kazakhstan. The subject of the study is the management of the decision-making process in assessing the consumer capabilities of potential customers of car dealerships, the process of forecasting car pricing.
A method using a global search engine optimization algorithm, a forest conveyor line with a random forest model with Bayesian optimization (RFBO), is proposed.
The algorithm of the method is as follows:
– obtaining and processing initial data taking into account the degree of uncertainty;
– formation of the optimization vector;
– creation of descendant vectors;
– ordering of vectors in descending order;
– reducing the dimension of the feature space;
– knowledge base training.
In the presented work, data from websites www.m.Kolesa.kz, www.Cars.com and the average values of the median salary in the Republic of Kazakhstan were used to create a knowledge base, the program code of the platform was created using the Visual Studio Code in the Python language.
The task to be solved was to predict car prices and assess the consumer capabilities of potential car dealership customers.
We evaluate our solution based on a dataset that was created by analyzing several car classified sites and data on potential customers. Our results show that the accuracy of the model training was 92.1 %, and the accuracy of forecasting car prices and evaluating the consumer capabilities of potential customers was 87.3 % – this is primarily due to lower prediction errors than those of the estimated regressors using the same set of input data, high-quality object mapping and a more competitive RFBO algorithm, superior to simple linear models.
The developed software solution should be used for making automated management decisions by car dealerships and credit organizations

The object of the study is decision support systems. The subject of the study is the decision-making process in management problems using the flying squirrel algorithm (FSA), an advanced genetic algorithm and evolving artificial neural networks.
A solution search method using an advanced FSA is proposed. The study is based on the FSA algorithm for finding a solution regarding the state of an object. Evolving artificial neural networks are used to train FSA, and an advanced genetic algorithm is used to select the best FSA. The method has the following sequence of actions. Input of initial data and setting agents on the search plane take place. After that, numbering FSA in the flock and setting the initial fitness function are carried out. Then, the quality of food in the FSA search area is determined, and the classification of trees (food sources) for FSA is carried out. The next step is the creation of new locations by FSA gliding, formation of the FSA action algorithm in the presence of a predator. After that, the FSA seasonal monitoring conditions are checked, the stop criterion is checked, and new FSA positions are generated taking into account the degree of data noise.
The originality of the proposed method lies in setting FSA taking into account the uncertainty of the initial data, advanced global and local search procedures taking into account the noise degree of data on the state of the analysis object. The method makes it possible to increase the efficiency of data processing at the level of 21–25 % due to the use of additional advanced procedures. The proposed method should be used to solve the problems of evaluating complex and dynamic processes in the interests of solving national security problems

Published: December 2023

A neural network was developed to predict the effect of phosphorus on spring wheat yields. The focus is on the neural network, including its structure, parameters, training methods and results related to phosphorus effects on spring wheat yields. An algorithm for developing a neural network model is also presented.
The study was conducted to address the critical need for developing a neural network to predict the effect of phosphorus on spring wheat yields in the Republic of Kazakhstan.
For data analysis, input data were used that cover the period from 2012 to 2022, including climatic indicators, regional features and phosphorus application. The target variable is spring wheat yield. To ensure the accuracy of the study, the data were preprocessed and standardized, and an outlier and variance analysis was performed. The developed neural network was trained and tested to obtain the best results. The mean squared error was used as a metric for evaluating the quality of forecasting. Additionally, indicators such as mean absolute error and coefficient of determination were considered.
The results of the study showed an MSE of 7.12, indicating that the model agrees well with the data and makes accurate predictions, which also suggests its practical relevance. The correlation analysis of the features showed that phosphorus application and spring wheat yield have a positive relationship. These results can be very useful for agriculture and farming enterprises, as they allow optimizing phosphorus application to the soil and increasing wheat yields
