Consideration of ways to improve the efficiency of deep well drilling

The object of the research is the composition of the bottom of the drill string when installing screw amplifiers. One of the biggest problems is the place of installation of the screw amplifier in the arrangement of the bottom of the drill string and its influence on the dynamic properties of the rock-crushing tool. The results of the study of the influence of the use of a screw amplifier on the efficiency of drilling deep wells were obtained. According to the results of research, it was determined in particular that the imposition of vibrations often causes a change in the nature of the interaction of the bit with the hole rock, therefore, the installation of the amplifier at different points of the layout will have different effects on the drilling performance. It is shown that the kinetic energy accumulated by the weighted drill pipes, when the amplifier is installed above the bit, is transmitted through the screw mechanism to the rock-destroying tool (bit) and is an operation that leads to an increase in drilling performance. Thanks to the conducted research, it has been proven that the property of the drill string elements and the disturbances of the oscillatory processes of various nature acting on them are related to the dynamic loading of its elements due to the installation of the amplifier in different places of the layout of the bottom of the string. This is due to the fact that the proposed screw amplifier is used with a friction fuse, which causes the rotary movement of the screw under the action of the torque and the translational movement of the nut together with the overbit mass attached to the bit. In most practical cases, especially during deep drilling, bits fail due to the destruction of the rolling bearings of the roller bit, which leads to jamming of the roller bit and leaving them in the holes. For practical use, the proposed design uses a friction fuse, which connects the bit to the drill pipe column through an elastic element. Analytical studies and performed calculations show that this screw amplifier will effectively ensure the destruction of any rocks, especially during overloads without slippage of reaches and be used for the construction of wells in native mining and geological conditions.

Study of the Structure and Properties of Concrete Modified with Nanofibrils and Nanospheres

The application of modifying nanoadditives in the technology of cement composites is currently a relevant and widely researched topic in global materials science. The purpose of this study was to investigate new nanoadditives—nanofibrils made from synthesized wollastonite (NF) and nanospheres from corundum (NS)—produced by LLC NPK Nanosystems (Rostov-on-Don, Russia) as a modifying additive. During the experimental investigations, the mechanical properties of cement pastes and concrete were examined. This included an analysis of the density, compressive and bending strength, as well as water absorption of concrete that had been modified with NF and NS additives. X-ray phase and microstructural analyses of concrete were performed. It was established that modification of cement composites with NF and NS additives had a beneficial effect on their properties, and the optimal amount for both types of additives was 0.3% by binder weight. The highest recorded enhancements in compressive and flexural strength of concrete with 0.3% NF were 7.22% and 7.04%, respectively, accompanied by a decrease in water absorption by 4.70%. When modifying concrete with 0.3% NS, the increases in compressive and flexural strength were 2.71% and 2.48%, and water absorption decreased by 1.96%. Modification of concrete with NF and NS additives did not have a significant effect on the change in concrete density, which was no more than 1%. Based on the results of phase analysis, it was established that concrete with NF and NS additives were characterized by the presence of five main phases: quartz, portlandite, calcite, larnite, and olivine-Ca. It was found that compositions with 0.3% NF and NS differed from the control composition by the presence of such a phase as olivine-Ca. Microstructural analysis confirmed the effectiveness of NF and NS additives. The microstructure of the modified concretes was distinguished by the extensive occurrence of clusters composed of calcium silicate hydrate zones. The conducted studies prove the possibility of using NF and NS as modifying nanoadditives in the technology of cement composites. The addition of nanofibrils from synthesized wollastonite is the most effective and promising and is recommended for use in real construction practice.

A bluffer’s guide to academic literacies: can we communicate a complex set of ideas in simpler terms?

I have often felt sceptical about the idea of academic literacies (AL), which presents a highly influential account of ‘how students learn to write at university’ (Lea and Street, 1998). AL theory has had a significant impact on the field, but some things about it bother me. Key ideas are frequently expressed in very abstract terms (it is hard to justify this comment in an academic context, but bear with me). Research has recognised difficulties in outlining AL’s core principles to students (Lea, 2016, p.91), and ‘the exact nature of the relationship between [its component] approaches’ (Hilsdon, Malone and Syska, 2019). It can be hard to convert the lofty AL aims of emancipation or transformation into practice. As theories go, it clearly thinks of itself as on ‘the right side of history’, and perhaps it is. However, having recently spent time wrangling with AL literature, I have developed more of a (grudging) respect for its insights and possible uses in practice. Drawing on theoretical writing and case studies of AL in use, this session aimed to identify the AL insights which are most relevant for the day-to-day practice of Learning Developers and present them in more concrete terms. In doing so, I hope to make this theory ‘meaningful, relevant and accessible to all’ (for Hockings’ definition of ‘inclusive’, see Hockings, 2010, p.1). After brief comments on its context and aims, I presented a short series of my ‘translations’ from AL into everyday English for use in everyday Learning Development practice.

Barriers to access to local produce in an early childhood setting in rural Appalachia

This case study examines young children’s access to fresh local produce in childcare settings in rural Appalachia. In-depth, semi-structured interviews with childcare center directors participating in farm to early care and education programming were conducted in the spring of 2023. Centering the per­spective of childcare directors, this research explores why farm to school programming is diffi­cult to implement. It specifically addresses the bar­riers preventing early childcare centers from pro­viding access to fresh and local produce to enrolled children. Eight primary obstacles to implementing farm to early care and education programming were identified: lack of staff; too wide a variety of tasks for directors; the “extra” work that fresh pro­duce requires; lack of knowledge about how to grow food; lack of required kitchen equipment; need for additional funding; unclear or out-of-date regulations about food safety; and a lack of paren­tal time. Limitations of the research include the specific geographic location of the study and the long-lasting implications of the COVID-19 pan­demic. Recommendations drawn from this case study include improving communication between childcare centers and regulatory agencies; creative use of alternative gardening practices; participating in a regional food hub; and improved funding.

Exploring factors influencing complementary feeding practices of mothers with infants aged 6-23 months in Sidoarjo Regency, Indonesia: A qualitative study

Complementary feeding (CF) is crucial in a child’s first thousand days of growth. This study aimed to explore the factors influencing mothers’ use of CF practices in the Sidoarjo Regency. We conducted a descriptive qualitative study in June-August 2023 in Sedati District, Sidoarjo Regency and collected information from ten mothers with children aged 6-23 months using purposive sampling. In-depth interviews were carried out to gather data on the mothers’ experiences and perspectives regarding CF practices. The qualitative data were interpreted using thematic analysis. The three key themes were emanated included ‘complementary feeding practices’, ‘individual perspectives’, and ‘social support’. The result highlighted the diversity of practices, varying individual beliefs, and the impact of support systems. These findings provide insights into the complexities of CF practices and underline the need for targeted educational programs and support systems to enhance CF practices.

Comparing the Validity of CAM-ICU and CAM-ICU-7 for Delirium Assessment based on Simulation

Purpose : This study aimed to compare the validity and user evaluations of the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) and its 7-item version (CAM-ICU-7) for delirium assessment. Methods : Thirty-six intensive care unit (ICU) nurses from four university hospitals participated in this simulation-based methodological study. Four standardized patients with normal cognition, subsyndromal delirium, hypoactive delirium, and hyperactive delirium were recruited. The participants assessed all four standardized patients using the CAM-ICU and CAM-ICU-7. We analyzed the validity, assessment time, and user evaluations of both tools. DeLong’s test and the paired t-test were used for comparisons. Results : The CAM-ICU showed sensitivity, specificity, and accuracy of 80.6%, 94.4%, and 84.0%, respectively, with an Area Under Curve (AUC) of 87.5%. CAM-ICU-7 demonstrated a sensitivity, specificity, and accuracy of 90.7%, 97.2%, and 92.4%, respectively, with an AUC of 94.0%. The CAM-ICU-7 showed a better AUC than the CAM-ICU for detecting subsyndromal delirium (<i>p</i> =.029). However, the CAM-ICU-7 required more time for assessment across all patient types (<i>p</i>＜ .001). ICU nurses reported that the CAM-ICU was faster to administer, whereas the CAM-ICU-7 was easier to use, better at detecting delirium, more effective at reflecting changes in delirium, and had a higher intention to use in clinical practice. Conclusion : The CAM-ICU-7 demonstrated superior validity compared to the CAM-ICU. Despite requiring more time, ICU nurses evaluated the CAM-ICU-7 as more useful. These findings support using the CAM-ICU-7 for delirium assessment in ICU settings.

중국인 학습자의 신문 기사 제목 이해 연구: 고급 학습자의 어휘력을 중심으로

Objectives The purpose of this study is to measure how vocabulary knowledge(both quantitative and qualitative) affects Chinese advanced learners when they understand the newspaper title. Methods To this end, a preliminary experiment was first conducted with four advanced learners (2 at Level 5 and 2 at Level 6). The preliminary experiment was used to address any ambiguities in the test materials and to adjust the number and order of the presented items. Based on the results of the preliminary experiment, a formal experi-ment was carried out with 60 advanced Chinese learners, divided into two phases: the first phase and a second phase involving post-experiment interviews. Additionally, this study conducted a statistical analysis of the col-lected data using SPSS 24.0, employing independent sample t-tests and paired sample t-tests. Results As a result, since advanced learners already have a certain quantitative vocabulary knowledge, there is little obstacle to understanding the title of newspaper without specific vocabulary. Conversely, it was found that a lack of qualitative vocabulary knowledge made it difficult to understand the title of newspaper with specific vocabulary. In particular, in the case of ‘vocabulary with figurative meaning’ and ‘the idiomatic phrases’ of the newspaper title, it was found that learners had more difficulty understanding the newspaper title. Conclusions Therefore, in order to improve the skilled vocabulary and practical vocabulary use of foreign learners, it is necessary to devise educational methods for these vocabulary in the future.

Extending the π‐Conjugation of a Donor‐Acceptor Covalent Organic Framework for High‐Rate and High‐Capacity Lithium‐Ion Batteries

AbstractRealizing high‐rate and high‐capacity features of Lihium‐organic batteries is essential for their practical use but remains a big challenge, which is due to the instrinsic poor conductivity, limited redox kinetics and low utility of organic electrode mateials. This work presents a well‐designed donor‐acceptor Covalent Organic Framework (COFs) with extended conjugation, mesoscale porosity, and dual redox‐active centers to promote fast charge transfer and multi‐electron processes. As anticipated, the prepared cathode with benzo [1,2‐b:3,4‐b′:5,6‐b′′] trithiophene (BTT) as p‐type and pyrene‐4,5,9,10‐tetraone (PTO) as n‐type material (BTT‐PTO‐COF) delivers impressive specific capacity (218 mAh g−1 at 0.2 A g−1 in ether‐based electrolyte and 275 mAh g−1 at 0.2 A g−1 in carbonate‐based electrolyte) and outstanding rate capability (79 mAh g−1 at 50 A g−1 in ether‐based electrolyte and 124 mAh g−1 at 10 A g−1 in carbonate‐based electrolyte). In addition, the potential of BTT‐PTO‐COF electrode for prototype batteries has been demonstrated by full cells of dual‐ion (FDIBs), which attain comparable electrochemical performances to the half cells. Moreover, mechanism studies combining ex situ characterization and theoratical calculations reveal the efficient dual‐ion storage process and facile charge transfer of BTT‐PTO‐COF. This work not only expands the diversity of redox‐active COFs but also provide concept of structure design for high‐rate and high‐capacity organic electrodes.

Relevance: The adhesive activity of the oral microbiome to new generation materials is the subject of study by the global medical community, and the issue of choosing structural materials is still being discussed in the scientific community and is of a controversial nature. Objective: To study the adhesion of representatives of the oral microbiome to samples of modern dental materials under experimental conditions (in vitro). Materials and methods: Samples of photopolymer resins for 3D printing: Dental Crown LCD, Dental Sand A1-A2, Dental Clear Pro, (n=30), (1-3 groups), thermoforming plates for vacuum forming: EV Gasket Bleaching 080, Bioplast multicolor 3.0*123 mm, Bioplast color 3.0*125 mm (n=30), (groups 4-6); clinical isolates of the microbiome as test strains: Staphylococcus aureus, Streptococcus oralis, Neisseria subflava, Actinomyces oris, Candida albicans (n=5). Research methods: experimental, microbiological, cultural, analytical and statistical. Results: The degree of adhesion of representatives of the oral microbiome to the studied structural materials is in the range from 0 to 4.91 (Ia) and depends on both the species composition of the microbiome and the physico-chemical properties of the materials. The high adhesion index for all microbiota groups was noted for vacuum forming materials (4.91), and the lowest was Dental Crown LCD (0), which makes it possible to recommend it for practical use. Conclusions: The choice of structural material should be made, including taking into account the adhesive activity of the oral microbiome in order to reduce the risk of complications. It is recommended to give preference to materials with a low adhesive activity index.

Surfactant-driven modifications to AlFeO3 for degradation of emerging antibiotic contaminants

We show that residues of unused antibiotics Sulfamethoxazole (SMZ) and tetracycline (TC) in wastewater can be treated by photocatalytic degradation. Here, a magnetic photocatalyst known as aluminum ferrite (AlFeO3) is employed to assess the degradation of SMZ and TC under visible light conditions. The structural and functional properties of co-precipitated AlFeO3 with four different surfactants are examined. The little-known relevance of surfactant usage in AlFeO3 synthesis, its characteristics, and its impact on emergent particle morphology for SMZ and TC degradation is reported. The results indicate that the catalyst can completely (100 %) degrade SMZ and TC in ∼60 mins. We propose a distinct degradation pathway for the same. Significantly, AlFeO3 can decompose TC and SMZ to yield rather small compounds (m/z ∼ 60), thereby showing potential for practical use. Also, the use of different surfactants indicates that surface potential plays a significant role in photocatalytic degradation. Despite the large size and low surface area, AlFeO3 performed well due to the surface potential of the catalyst. Findings suggest that using bulk catalysts with adjusted surface potentials offers sufficient performance, thereby bypassing the need for nano-sizing and concern about nano-toxicity. Further, the magnetic property of AlFeO3 facilitates the recovery and reuse of the catalyst post-degradation.

Identifying possible ways for adapting an open wagon for transporting containers

The object of this study is the processes of perception and redistribution of loads in the supporting structure of a open wagon loaded with containers, taking into account the new scheme of their fastening. For safe transportation of containers in an open wagon, it is suggested to use a removable module. This module works according to the principle of an intermediate adapter between the container and the open wagon body. Fastening of the module itself in the open wagon is carried out through the fitting stops, which are placed on the floor of the open wagon. Mathematical modeling was carried out to determine the longitudinal dynamic load acting on the container fixed according to the new scheme in the open wagon. To this end, a mathematical model was built that characterizes the longitudinal movements of the "open wagon - removable module - container" system. Determination of the accelerations that act on the supporting structure of the open wagon loaded with containers was also carried out by means of computer simulation. Verification of the formed model of the dynamic load of the open wagon was carried out according to the F-criterion. Also, as part of the study, a modal analysis of the load-bearing structure of a open wagon loaded with containers was carried out, which made it possible to assess its traffic safety. A feature of the results obtained as part of the research is that the proposed design of the removable module could be used not only for fastening containers but also for transportation of other types of cargo. The field of practical application of the results is railroad transport, including other transportation industries. The conditions for the practical use of the results are a symmetrical scheme of loading the body of a open wagon with containers. The results of this study will contribute to increasing the efficiency of container transportation and the profitability of railroad transport

Development of data-efficient training techniques for detection and segmentation models in atrial septum defect analysis

The object of this research is to develop a data-efficient pipeline for the detection of atrial septal defects (ASDs) using echocardiographic images. ASDs are common congenital heart defects that can lead to serious health issues if not diagnosed early. Rising mortality rates due to undetected ASDs highlight the urgent need for improved diagnostic methods. To address the problem of limited annotated medical data hindering accurate detection models, this study fine-tuned the SegFormer model for precise segmentation of cardiac structures in echocardiography images, focusing on the four-chamber heart view essential for ASD detection. By integrating SegFormer with the YOLOv7 detection model, known for real-time object detection, the ASD regions within the segmented heart structures were accurately identified. This cross-referencing ensures anatomically accurate diagnoses and reduces false positives. The study results demonstrate that despite limited data, the integrated method achieves high accuracy and speed, outperforming traditional models. This improvement is explained by the synergy between SegFormer’s transformer-based segmentation and YOLOv7’s efficient detection capabilities. The distinctive feature of our approach is the successful integration of these models in a data-efficient manner, enabling effective ASD detection even with scarce data. The scope of practical use includes deployment in clinical settings with limited resources, requiring only echocardiographic equipment and basic computational resources. By providing clinicians with a reliable tool for ASD detection, the study supports timely interventions in pediatric cardiology, ultimately improving patient outcomes and enhancing care consistency

Microporous Polyethylene and Cellulose Composite Separators for Reversible Lithium Electrode in Lithium Rechargeable Batteries

AbstractThe lithium metal anode is the best candidate for high energy density batteries because of its high specific capacity and low negative potential. Rechargeable lithium metal batteries (RLMB) have not yet been commercialized. The key factors that limit the practical use of RLMB are the formation and growth of lithium dendrites during the lithium deposition process and the reaction of the lithium anode with the organic solvent of the electrolyte, quantified by the Columbic efficiency (CE). To suppress the lithium dendrite formation and to improve CE, many approaches such as the formation of a protective layer on the lithium electrode and the use of additives to the electrolyte have been proposed. In this study, the effect of a thin cellulose film to improve CE of lithium deposition and stripping on the lithium electrode was examined. The cycle performance of a Li/Li symmetrical cell with a cellulose and polyethylene composite separator was examined for a carbonate electrolyte and an ether electrolyte. The improvements of CE were observed for both electrolytes with the cellulose film separator. The improvement could be explained by the good wettability of the cellulose film separator with the electrolyte.

Implementation of spectral methods on Ising machines: toward flow simulations on quantum annealers

Abstract We investigate the possibility and current limitations of flow computations using quantum annealers by solving a fundamental flow problem on Ising machines. As a fundamental problem, we consider the one-dimensional advection-diffusion equation. We formulate it in a form suited to Ising machines (i.e., both classical and quantum annealers), perform extensive numerical tests on a classical annealer, and finally test it on an actual quantum annealer. To make it possible to process with an Ising machine, the problem is formulated as a minimization problem of the residual of the governing equation discretized using either the spectral method or the finite difference method. The resulting system equation is then converted to the Quadratic Unconstrained Binary Optimization (QUBO) form through the quantization of variables. It is found in numerical tests using a classical annealer that the spectral method requiring a smaller number of variables has a particular merit over
the finite difference method because the accuracy deteriorates with the increase of the number of variables. We also found that the computational error varies depending on the condition number of the coefficient matrix. In addition, we extended it to a two-dimensional problem and confirmed its fundamental applicability. From the numerical test using a quantum annealer, however, it turns out that the computation using a quantum annealer is still challenging due largely to the structural difference from the classical annealer, which leaves a number of issues toward its practical use.

Temperature stable (1-x)BaAl2Si2O8-xBa3V2O8 (0.2 ≤ x ≤ 0.5) microwave dielectric composite ceramics for LTCC applications

BaAl2Si2O8 microwave dielectric ceramics possess dielectric properties of low permittivity (εr) and low loss, coupled with low synthesis cost, making them promising for commercialization. However, the hexagonal structure undergoes high-temperature phase transitions that deteriorate thermal shock resistance and durability, hindering its practical use. In this work, we report temperature-stable BaAl2Si2O8-Ba3V2O8 low temperature co-fired ceramics (LTCC). The combination of Ba3V2O8 and G9 glass achieved a near-zero τf and a thermal expansion coefficient of ∼ 8.5 ppm/℃, significantly enhancing the temperature stability of BaAl2Si2O8 ceramics. By employing ion substitution and enhancing lattice disorder, the components of G9 glass were strategically designed to successfully induce hexagonal-to-monoclinic transformation of BaAl2Si2O8 phase. The dielectric properties of 0.5BaAl2Si2O8-0.5Ba3V2O8-9 wt% G9 sintered at 900 ℃ were εr ∼9, Q×f ∼22,000 GHz and τf ∼ +1.9 ppm/℃. Good chemical compatibility with silver powders was confirmed by further investigation of the co-firing behavior. This work provides attractive candidate for BaAl2Si2O8-based LTCCs and an available approach for modifying BaAl2Si2O8 ceramics.

Human capital development practices and performance of business organizations in imo state

The study examined human capital development practices and performance of business organizations in Imo State. It specifically focused on the influence of developmental human capital development and collaborative human capital development practices on market share and customers’ satisfaction of business organizations. The study employed a descriptive survey research design. The population of the study was 96 (ninety-six) registered business organizations in Imo State. The entire population of the study was used due to its manageable size. Data was collected with a structured questionnaire designed by the researchers. The questionnaire was validated by two professionals in the field of measurement and evaluation of the principal researcher’s institution, and the reliability of the instrument was determined with test re-test which yielded a coefficient of 0.87. Data was collected through physical contact with the respondents. Data collected was analyzed with mean and standard deviation. Analysis of the data collected revealed that both developmental and collaborative human capital development practices have positive influence on both market share and customers’ satisfaction of business organizations. Thus, it was recommended that: management of organizations should prioritize the use of developmental human capital development approaches like training and development, performance appraisal, and performance counseling to prepare their employees for higher performance; and management of organization should encourage the use of collaborative human capital development practices like goal setting, role-clarification, and interpersonal relations to increase the productivity of their employees.

The Effectiveness of Applying Evidence-Based Practices Based on the Torres Model and its Impact on Improving the Teaching Competencies of Special Education Teachers

The use of evidence-based practices (EBPs) in the field of special education requires full awareness from special education teachers of how to choose and successfully apply EBPs, which contribute greatly to improving the learning outcomes of their students and may even contribute more to raising the level of teaching competencies (TCs) in these teachers. The current research aimed to apply EBPs according to the Torres model (TM) and examine their impact on improving TCs. The sample consisted of 64 special education teachers in Al-Ahsa. The research employed a quasi-experimental approach using components developed by the researcher: a card of EBPs evaluation, a scale of TCs, and a training program. The results showed the superiority of the first experimental group (which was trained according to the TM) over the second group (which was trained in the usual way) in applying EBPs and TCs. The research recommended the importance of knowledge and application of the TM by special education teachers to ensure the successful practice of EBPs with their students and to raise the level of teachers' TCs.
