BINDERS FROM SECONDARY RAW MATERIALS OF COAL ENRICHMENT WASTE FOR CONSTRUCTION OBJECT ERECTION USING THE 3D PRINTING METHOD
Authors: Rudin A.A. 
Published: September 2024

Formulation of the problem. The 3D printing construction technology is one of the modern methods of rapid construction, which allows for a significant automation of the building process while achieving high precision in the fabrication of complex configurations using equipment (3D printers) controlled by software to define precise coordinates of the printed structure model. The main materials for construction 3D printing technology are composite mixtures based on binders. Cement or composite binders can be used as binders [1]. The cement production technology involves the firing of its components at 1 450 °C, which requires significant energy resources and affects its final cost and the overall mixture. The utilization of coal enrichment waste, which contains clay minerals, quartz, pyrite, and a small amount of carbonates, impurities, and combustible substances, allows for reducing the consumption of technological fuel and the firing temperature of the binder by harnessing the heat-generating properties of coal inclusions. Thus, coal enrichment waste can be used as a fuel component in obtaining the binder. The purpose. Based on the conducted research, it can be concluded that the use of component binders derived from coal enrichment waste shows promise in the construction of buildings using 3D printing technology. By harnessing the heat-generating properties of these waste materials, it is possible to reduce the consumption of technological fuel and firing temperature required for binder production, consequently lowering CO2 emissions into the atmosphere and reducing the final cost of the construction mixture for 3D printing.

Authors: Korolyanchuk D.G. , Ovcharenko V.I. , Girin O.B. 
Published: September 2024

Purpose of research. The main factors that reduce the protective properties of electrocrystallized coatings are the formation of volumetric defects − pores, as well as the occurrence of microgalvanic couples at grain boundaries, that is, on surface defects of the crystalline structure. Creating a non-porous structure in electrocoatings, eliminating the formation of surface defects in metal/alloy layers, as well as the possibility of replacing chromium coatings, which are obtained from toxic electrolytes, are urgent tasks. Materials and methodology. In the work, it was proposed to use electrocoatings with Ni−P alloy as protective layers on products that increase corrosion resistance. An X-ray determination of the phase composition of Ni−P electrochemical deposits was carried out. The surface morphology and corrosion resistance of coatings were studied. Results. Samples of electrochemical coatings of pure nickel and nickel-phosphorus alloy were studied. It has been established that during the formation of nickel coatings with the addition of phosphorus ions, the surface morphology has practically no pores, amorphization of deposits occurs, due to which the protective properties, namely, corrosion resistance, are improved. Scientific novelty. Factors have been identified that influence the increase in corrosion resistance of coatings − the absence of a porous structure and the formation of an amorphous state. Conclusions. The influence on the structure and properties of electrochemical coatings of a nickel-phosphorus alloy has been studied. It has been established that the addition of phosphorus ions to the nickel plating electrolyte leads to the formation of an amorphous structure in the coatings, and layers of the Ni−P alloy appear practically without the presence of pores. It has been established that the effect of increasing the corrosion resistance of the electrochemical coating with a nickel-phosphorus alloy (by 30 %) is due to the formation of an amorphous structure of the solidifying metal liquid while preventing the crystallization process during electrochemical deposition.

Published: September 2024

Sources of information on the use of combined pest control measures for a sustainable ecofriendly environment are germane in poultry production. A multistage sampling procedure was used to select 120 respondents using an interview schedule. Data collected on socioeconomic characteristics, sources of information, pest prevalence, constraints, and utilisation of Integrated Pest Management (IPM) in Kwara State were analysed with percentages, frequency, weighted mean score, mean, Chi-square, and Pearson’s Product Moment Correlation at α 0.05. The result shows that respondents were members of the Poultry Association of Nigeria (PAN) (96.7%) with mean age and years of business experience were 43.0±9.9 and 7.3±5.8years respectively. Most of the respondents had tertiary education (84.2%) and produced broilers (51.7%) in four cycles a year (57.5%). The most utilized IPM information sources were from co-farmers (68.3%) and workshops (67.5%); with the most prevalent pest being flies (x̅=1.48) and was low for 54.2% of the respondents. The respondents’ most utilised IPM method was the prompt elimination of dead birds from the flock (x̅=2.86) which was high for 60%. However, respondents’ most prominent constraint to IPM usage was the government’s insufficient pesticide subsidy (x̅=2.69); and was high for 60.0%. A significant relationship existed between respondents’ IPM usage and sources of information like family (X2=0.938; p=0.005) and internet (X2=1.000; p=0.000); years of education attainment (r=0.022; p=0.021), prevalent pest (r=0.577; p=0.051) and constraints to IPM usage (r=0.186; p=0.012). IPM information sources positively influence its utilisation, hence such sources should be empowered by the relevant stakeholders for a sustainable eco-friendly environment.

Published: September 2024

Differential-pressure pipe sticking is one of the main problems that occurs during drilling operations, leading to an increase in the non-productive time (NPT). To address this problem, the industry uses a range of spotting fluids to enable the recovery of a differentially stuck pipe effectively. Thus, any delay in solving this problem can turn into a difficult rescue operation that can eventually lead to the abandonment of the well in extreme conditions. Therefore, it is crucial to choose the appropriate spotting fluid that is suitable for the specific mud composition, as using an unsuitable spotting fluid may result in dangerous conditions. Additionally, other factors can further complicate the process of freeing a stuck pipe. Therefore, for prevention, remediation, and enhancing the recovery of stuck pipes, it is important to understand the root causes of the pipe sticking issue, the conditions that lead to it, and the operational mechanisms of various spotted fluids and their application areas.
This paper studies the challenges of pipe sticking during drilling operations, particularly emphasizing differential pipe sticking, and the role of spotting fluids in releasing pipe sticking. It discusses the testing and evaluation methods used to choose appropriate spotting fluids while rejecting the inferior options, highlighting the benefits and disadvantages.
This study, which was conducted at Well NR-A in the Nahr Umr field in southeastern Iraq, aims to address the problem of differential stuck pipes. By employing a stuck pipe list check table, the mechanism of this problem was diagnosed, resulting in a thorough analysis of the causes of differential stuck pipe and subsequent steps necessary to release the stuck pipe. Finally, recommendations are presented to improve testing and evaluation methods, overcoming the limitations of conventional methods.
Identifying the high potential zones for hydraulic fracture propagation / Eastern Baghdad field
Authors: Ihsan Amani , Al- Ameri Nagham Jasim 
Published: September 2024

For a reservoir with high storage capacity and low ability to produce, the serious problem is the sharp reduction in the recorded well productivity within a short period. One solution to this problem is to create hydraulic fractures that increase formation permeability and keep its production at high rates for a sufficient time. The field under study is the East Baghdad oil field of three formations: Saadi, Tanuma, and Khasib. Knowing the geomechanical behavior of these reservoirs has a critical effect on the success of hydraulic fracturing operations. In this study, rock stress magnitude and direction, rock elasticity, rock strength to fracturing initiation, and all these parameters in addition to petrophysical properties will be used to identify whether the hydraulic fracturing operation could be successful or not. An integrated modeling of the studied reservoir is an essential step including 1-D geomechanical evaluation of many formations in order to choose the perfect layer to create hydraulic fracture. Then, a 3-D distribution of geomechanical properties and petrophysical properties was presented to make a perfect selection of these properties. The geomechanical evaluation of the reservoirs under study is supported by experimental evaluation of core samples including Energy Dispersive X-ray spectroscopy (EDS), Scanning Electron Microscopic (SEM) image, and thin section (TS) image. The results show that a reduction in the calculated geomechanical properties in terms of Poisson ratio young modulus and compressive strength are favorable for candidate layer selection. Among the studies of rock mechanical properties, it is also noticed that unconfined compressive strength is a crucial parameter for best layer selection. The suitable depths for fracturing jobs are given in detail in this study using brief data collected from four wells.

Выявление ненормативной лексики является важнейшей задачей, позволяющей создавать эффективные системы модерации контента в современной цифровой эпохе. Но когда нет аннотированного материала, это становится особенно сложным на языках с ограниченными ресурсами. Данное исследование в первую очередь занимается поиском ругательств на казахском языке, который считается малоресурсным языком. Чтобы решить эту проблему, мы создали новую тактику, основанную на сетях долговременной двунаправленной памяти (BiLSTM), которые продемонстрировали удивительную эффективность в задачах обработки естественного языка. Благодаря двунаправленному компоненту архитектуры BiLSTM мы можем фиксировать как долгосрочные зависимости, так и контекстные отношения во входном тексте. Это позволяет лучше распознавать ненормативную лексику. Чтобы уменьшить нехватку аннотированных данных в условиях с ограниченными ресурсами, мы также применяем стратегии трансферного обучения.
Мы показываем эффективность предложенного нами метода с помощью обширных экспериментов с набором данных казахского оскорбительного языка, что дает самые современные результаты в распознавании оскорбительной речи на казахском языке с низким уровнем ресурсов. Кроме того, мы исследуем эффективность нашей стратегии, используя различные настройки моделей и подходы к обучению. Результаты этого исследования дают ценную информацию о методах обнаружения ненормативной лексики на языках с ограниченными ресурсами и открывают путь к разработке более эффективных систем модерации контента, адаптированных к конкретным языковым контекстам.

The current study aimed to find out the prevalence of nonspecific lower back pain among the nurses of medical wards and emergency units. For this purpose, a cross-sectional study was conducted in various public and private hospitals in Okara, Pakistan. A sample size of 150 female nurses was considered for the study. Moreover, convenient sampling technique and questionnaires were used along with the Oswestry Disability Index to evaluate the lower back pain and the Numeric Pain Rating Scale was used to gauge its severity. Data analysis was performed using SPSS version 22 software.Among 150 female nurses, 44.7% were between 20-30 years old, 36.0% were aged 31-40, and 19.3% were aged 41-50. Out of these 150 female nurses, 61 worked in the medical ward and 89 were working in the emergency department. Statistical analysis with a p-value < 0.05 indicated a significant difference in the occurrence of lower back pain between these two groups. The medical ward had a lower prevalence of 42.3% as compared to the emergency department that had 63.1%, respectively. Conclusively, it was observed that a significant work-related health concern is the incidence of non-specific lower backaches among nurses working in hospital wards and emergency rooms. As compared to nurses in medical wards, emergency room nurses appeared to experience more intensified lower back discomfort due to prolonged working hours.

Mastering Artifact Correction in Neuroimaging Analysis: A Retrospective Approach
Authors: Oliveira Alícia , Cepa Beatriz , Brito Cláudia , Sousa António 
Published: September 2024

The correction of artifacts in Magnetic Resonance Imaging (MRI) is increasingly relevant as voluntary and involuntary artifacts can hinder data acquisition. Reverting from corrupted to artifact-free images is a complex task. Deep Learning (DL) models have been employed to preserve data characteristics and to identify and correct those artifacts. We propose MOANA, a novel DL-based solution to correct artifacts in multi-contrast brain MRI scans. MOANA offers two models: the simulation and the correction models. The simulation model introduces perturbations similar to those occurring in an exam while preserving the original image as ground truth; this is required as publicly available datasets rarely have motion-corrupted images. It allows the addition of three types of artifacts with different degrees of severity. The DL-based correction model adds a fourth contrast to state-of-the-art solutions while improving the overall performance of the models. MOANA achieved the highest results in the FLAIR contrast, with a Structural Similarity Index Measure (SSIM) of 0.9803 and a Normalized Mutual Information (NMI) of 0.8030. With this, the MOANA model can correct large volumes of images in less time and adapt to different levels of artifact severity, allowing for better diagnosis.
