Published: November 2023

Mobile phone handsets utilized by individuals of all ages been heavily grows popular as a wireless communication device. Every mobile phone produces electromagnetic radiation at radio frequencies (RF). The specific absorption rate is used to calculate how much of this energy is absorbed by the human skull. Standard guidelines state that sold phones must fall below a specified SAR. This paper aims to evaluate the Specific Absorption Rate (SAR) and E-field strength for mobile phone radiation exposure on a head model who is 40 years old and a 5-year-old child. The human skull is represented in this model as a six-layered sphere made up of the brain, CSF, dura, bone, fat, and skin. Various layers of the head's SAR distribution have been measured as an impact of radiation from mobile phones exposure using the 1800 MHz frequency. Earlier research were used to consider the dielectric properties of tissue layers. The human head and mobile phone antenna is modelled in this research using ANSYS HFSS. A hand-held mobile phone's dipole antenna type is considered for RF exposure. It is seen how EM absorption in various tissue layers for both adults as well as child head. SAR comparisons between the adult and child head reveal that the child head absorbs greater power due to the distinctive layerwise head shape, conductivity, permittivity, and permeability of the two head models. Excess EM absorption may have negative physiologic implications for human health specifically impact on child physical and mental health.

Communication skills are an essential component to connect and interact with other individuals in an organization. Mastery in leadership communication is important for youth to become successful leaders. The aim of this study is to develop a measurement model of youth leadership communication. The youth’s leadership communication model consists of three constructs namely interpersonal communication, persuasive communication, and problem-solving skills. The questionnaire was distributed among 384 respondents from youth associations members in Terengganu, Malaysia. The data were analyzed using Amos version 23. The constructs and indicators were accepted as measurement elements, including the loading factor, average variance extracted (AVE), composite reliability (CR), the square root of AVE (√AVE) and at least three fit indexes accepted for model fitness. The results indicated all constructs were significant when the values of loading factor (0.852–0.964), AVE (0.834), CR (0.938), and the square root of AVE (0.913) achieved all the required criteria. The results of confirmatory factor analysis (CFA) from three constructs of youth leadership communication within the 31 indicators suggested were acceptable. Finally, this study successfully developed a measurement model of youths' leadership communication models. These models can be applied by youth to improve communication skills, individual and organizational leadership, and identify further research areas.

Hazard Risk Reductions Should Not Be Communicated as Relative Risk Reductions for Death in Cancer Clinical Trials: Intentional or Inadvertent?
Authors: Dueñas-Gonzalez Alfonso
Published: November 2023

In the last four decades, median survival has increased in advanced cervical cancer from 7.1 months with single-agent cisplatin to 24 months with doublet chemotherapy plus bevacizumab and pembrolizumab. Coinciding with the emergence of targeted therapy, we observe higher pricing of novel cancer drugs and results presentation aimed to positively impact the audience. The first could result in poor drug affordability and financial toxicity, while the second can give patients a magnified sense of progress. In this review, we briefly comment on study designs that may favor obtaining positive results but, most notably, how results are presented in the latest randomized clinical trials in advanced cervical cancer. We found that survival results are expressed in Hazard Risk (HR) reductions but communicated as a Relative Risk (RR) reduction for death. The HR of the control to the experimental regimen is given by exp[β]. An HR of 0.7 means an HR reduction of 30%. Risk reduction derived from HR may lead to a belief that the intervention can eliminate the chance of the event occurring, but a decreased HR means a reduction in the speed of the event happening, not the chances of it occurring. On the contrary, the “risk reduction” based on RR means that patients have less chance of having the event because RR is a binary measure (alive or dead). Furthermore, Absolute Risks and Number-To-Treat (NNT), in addition to Relative Risk, are omitted. The issue of how the results of cancer clinical trials are presented deserves open discussion. After all, it is the patient’s right to make an informed decision before embarking on any cancer treatment.

Published: November 2023

Access to healthcare is largely dependent on where you live and how much money you have. It is far from equally accessible to all. The National Health Service (NHS) was established in 1948 to improve access to reasonable standards of healthcare to all residents of the United Kingdom (UK) and to ensure that this was free at the point of delivery. The NHS has been described as ‘the envy of the world’ despite the well-documented challenges it faces. The NHS has driven quality and consistency of clinical care within the UK for decades, and along with universities and many other organisations, it has also fostered a reputation for excellent academic research and teaching. However, the long shadow of the UK’s colonial past on health care provision elsewhere is increasingly recognised. Far from producing and sharing its ‘commonwealth’ equally with people inhabiting the countries it colonised, the UK has been accused of exploiting them in a variety of ways. This opinion piece describes and discusses the past and present influence of the UK in African healthcare and offers some examples of practices that might facilitate improved clinical and academic outcomes for all marginalised people in the near future.

Published: November 2023

Ultrasonic testing results can be affected by differences in acoustic properties of the material under test such as attenuation and velocity. Weld flaws can be missed or incorrectly rated, or incorrectly located in the material. The goal of this study was improving the quality of ultrasonic testing of welds. The objective of the study was to assess the variation in acoustic properties of structural steels used for the construction of highway bridges. This paper discusses the results of measurements of the acoustic properties of 43 different material heats that show different grades of steel plate used in bridges. Normal incidence shear wave transducers were used to measure shear wave speeds and acoustic anisotropy ratios. Results showed significant variations in wave velocities in the different steels that is unaddressed in contemporary welding codes for bridges in the US.

Published: November 2023

Electro Magnetic Acoustic Transducer (EMAT) is one of the Ultrasonic Testing (UT) techniques frequently used for flaw detection, thickness measurements, and characterization of metals and metallic alloys. However, the manual inspection of components or structures using EMAT has several drawbacks. Firstly, it can be time-consuming, labor-intensive, and physically demanding, mainly if the components or structures are located in remote or hard-to-reach areas. Moreover, manual inspection is susceptible to human error and subjectivity, leading to inconsistencies and inaccuracies in the inspection results. Finally, a manual inspection can be expensive, especially if specialized equipment or personnel are required. To overcome these problems, we have designed a robotic system that contains two Universal Robots (UR) with a customized gripper attached to its tooltip. These grippers have EMAT sensors attached to the fingertips and a camera to help identify the position of the pipe. We made a few modifications to the gripper to optimize the point of contact and ensure that the EMAT sensors make good contact with the pipe. The attached stereo depth camera to the back of the gripper is used to get positional feedback for the UR5 robotic arms. We incorporated simple fiducial markers onto the pipe setup such that they were placed on spots on the pipe where we wanted to perform our tests. With the help of the stereo camera, we obtained the real-time position of these fiducial markers. We generated a motion path for the robotic arms to move from one position to another.

Published: November 2023

An ultrasonic spectroscopy method (UltraSpecTM) has proven to be useful for some inspections and material characterization studies where conventional NDE techniques were inadequate. Manual scanning can be time consuming and can result in arm fatigue, so an automated solution is desired. The automated solution must include discrete point acquisition, separate pitch and catch elements, a custom fixture, the ability to apply force perpendicular to the surface, 3D motion control and fine resolution. This paper highlights the successful integration of the UltraSpec method with a cobot (collaborative robot) as a portable, automated 3D scanning solution. The cobot automation was accomplished by defining the surface to be scanned using a laser profile scanner, creating a grid of acquisition locations, and controlling the data acquisition process within the UltraSpec software. The automated UltraSpec data acquisition results in a lower scan time, consistent force-feedback data collection, and improved position consistency.

Published: November 2023

The quality and mechanical properties of components built with metal additive manufacturing (AM) are highly dependent on the microstructure formed during solidification. There currently exists a need for ex-situ qualification of materials for accurate characterization of microstructural features. Here we investigate advanced laser-based ultrasound techniques for measuring microstructural features such as anisotropy and residual stress, which are common in AM fabricated metals. Here we employ zero group velocity (ZGV) resonances to characterize material anisotropy and to quantify uniaxial stress in tensile stress measurements of aluminum alloy dog bone samples.

Published: November 2023

Synthetic-aperture radar (SAR) imaging techniques are used for producing microwave and millimeter-wave 3D high-resolution images of multi-layered non-conductive composite structures. This paper presents the utility of SAR algorithms when imaging non-planar geometries. Generally, curved and non-planar geometries result in distortion and clutter in the produced SAR images due to variations in refractions and distances to the surface of the sample. These variations result in distortion and clutter in the resultant SAR images. Furthermore, multi-layered SAR algorithms are not applicable to such geometries, which limits the efficacy of the SAR algorithm. In order to reduce image distortion and allow for using multi-layered SAR algorithm, a method is described and used to compensate for variations in the distance of the antenna to the sample surface. After this compensation, multi-layered SAR algorithms are used to produce focused and clutter-free images.

Metal additive manufacturing (AM) is a critical capability for Industry 4.0, with particular potential in the aerospace and medical industries. Its ability to create dense metal parts with intricate geometries makes it appealing for demanding environments requiring specific thermal and mechanical properties, as well as long-term reliability. However, limitations such as low surface quality and buried porosity have hindered widespread adoption of metal AM. Numerous inspection and monitoring methods have therefore been explored to enhance the as-printed component quality. This study evaluates the feasibility of real-time 3D temperature field monitoring using eddy current (EC) measurements, particularly relevant for powder bed fusion (PBF) AM approaches. Analytical thermal and electromagnetic (EM) models were used to demonstrate underlying principles. By integrating thermal distribution maps into 3D EC numerical models, we calculate temperatures in AM-relevant materials using EC-induced voltages and EM signal features. Optimized EC frequencies were determined through experimentally-validated EM simulations.

Published: November 2023

The open-ended rectangular waveguide (OERW) technique is widely used for microwave materials characterization to simultaneously and accurately estimate thickness and electrical properties of layers in multi-layered structures. When evaluating thin (i.e., with respect to wavelength) and conductor-backed structures, one must consider a tradeoff between probe footprint and property estimation accuracy, which can be impacted by measurement error due to using a finite flange. This work investigates the utility of a waveguide iris, for certain applications, by which to limit effective probe footprint while reducing the measurement error caused by using a finite flange. Numerical simulation results show the potential effectiveness of using a square iris to decrease finite flange error and remain sensitive to changes in the structure’s properties.

The industrial revolution shifted the dependence on manufacturing from human labor to machinery. The world has embraced the production of complex geometries with higher throughput and lower material waste. AM is evolving in material selection and processing methods and has garnered interest in the manufacturing of critical and active parts for high-impact applications such as: aerospace, biomedical, energy and automotive sectors. The use of radiography, thermography, optical methods, ultrasound, and acoustic emission have effectively detected defects in AM. Some of the anomalies observed include residual warpage, cracking, poor fusion, and filament breakage. Natural printed surface of large format additive manufacturing (LFAM) has large and rough ridges for the surface finish. While post-process machining is an additional manufacturing process and adds on to time and cost, it also provides a smooth surface finish to the surface which reduces noise and attenuation of the acoustic waveform during the AE monitoring. This research investigates how surface roughness affects the acoustic waveform. Its findings demonstrate the optimal surface finish for AE to provide effective structural health monitoring (SHM) for LFAM. By understanding the effects of the interactions of the AM surface with the AE propagation and attenuation, this method becomes an effective method to identify defects in real time and increases the overall efficiency of the print process unlike other NDE methods that cannot actively detect defects during the print process.
Beta-Stabilized Ti-5Al-5Mo-5V-3Cr Primary and Secondary Phase Characterization using Ultrasonic Attenuation

Published: November 2023

Ti-5Al-5Mo-5V-3Cr (Ti-5553) is a beta-stabilized titanium alloy being evaluated for its use in additive manufacturing. The development of effective nondestructive characterization tools will be critical for successful insertion of Ti-5553 into applications. The microstructure of Ti-5553 can be modified significantly, through heat treatments alone, to produce single β-phase microstructure or dual α-β microstructure with variations on the types and quantities of the α phase in a β matrix. In this work, a set of heat treatments was chosen to obtain a range of microstructures, followed by an investigation of the ultrasonic response to gauge the degree to which these variations could be detected. Ultrasonic attenuation was selected because of its ability to detect differences in grain size and, potentially, the existence and limited details of secondary phases . Initial results show a very distinctive difference in attenuation between the single phase β and the α+β microstructures, and smaller, but still significant, differences among the α+β microstructures indicating that this approach merits further development.

Published: November 2023

Array element locations are a necessary input for ultrasonic imaging algorithms. This effort studies a recently developed algorithm that determines the relative array element locations of a flexible ultrasound array applied to a non-flat surface. A numerical investigation of the optimization-based method for determining relative array element locations compares the actual locations of the elements to those determined by the algorithm, and images produced with the actual element locations versus those estimated by the algorithm. The algorithm performance is evaluated in two example regions with complex boundaries. The error of relative array element location estimates is characterized, and the impact on the resolution of the total focusing method with full matrix capture is demonstrated.

Published: November 2023

The variability in ultrasonic attenuation of narrow-gap improved electroslag welds (NGI-ESW) and submerged arc welds (SAW) was assessed through experimental testing of machined weld specimens with side drilled hole (SDH) reflectors. The specimens were assessed using a 2.25 MHz conventional UT probe and a 5 MHz PAUT probe. NGI-ESW welds had significant variability depending on the position of the sound path in relation to the structure of the weld, with increased average attenuation and increased scatter in amplitude when sound passed through any portion of the weld metal. One NGI-ESW specimen was fabricated from with thermo-mechanically controlled processed (TMCP) base metal which resulted in additional scatter for scans through the base metal due to acoustic anisotropic behavior. SAW welds had much less attenuation variations than the NGI-ESW welds, but scans through the weld metal had larger amplitude variations than scans through the base metal only.

Published: November 2023

Purpose: This research aims to suggest a checklist for successful implementation of future community development projects by analyzing three community development projects implemented in the Tigray region of Ethiopia applying Sustainable Livelihood Framework (SLF).
Originality: While there exist various studies dealing with community development programs, there is only few studies that attempt to empirically analyze the positive effects and negative effects of community development programs. Thus, this research intended to empirically examine differences between development theories and practices using three projects that have been implemented in Tigray region.
Methodology: Case study was conducted through qualitative research methods such as Key Informant Interview, Focus Group Discussion in analyzing three community development projects implemented in Tigray region of Ethiopia. The elements of each project were analyzed based on 5 assets, strategies, and outcomes of the Sustainable Livelihood Framework(SLF) to evaluate the sustainability of the project.
Result: In the Koraro project, community participation in every stage was absent, which weakened the sustainability of the positive outcomes. Second, AbrehaAtsbeha project was community-based, participatory, and integrated, which led to agile implementation. Lastly, in Maymekden and Addis Alem project, meaningful community participation was not made, which resulted in unsustainable outcomes.
Based on these results, this study suggests that the success of community development projects depends on factors such as community participation and investments in livelihood assets.
Conclusions and Implication: This result implies for the development actors that the community development project outcomes should be sustained through local resources and build a sense of ownership in the community

Authors: Chabanenko D. V. , Farionik T. V.
Published: November 2023

Micronutrients, or micronutrients, are an essential component of the diet of farm animals and play a key role in their health and performance. The importance of trace elements in physiological processes and ensuring the normal functioning of the animal body is highlighted. Micronutrients affect growth, fertility, the state of the immune system, the health of the skin and coat, and metabolism. This scientific study emphasizes the importance of a balanced consumption of trace elements in the diet of farm animals to achieve high-performance indicators and ensure their overall health. It is essential to consider that the deficiency or excess of trace elements in the diet of animals can lead to various problems with health and productivity. Therefore, accurate, balanced nutrition and control over the content of trace elements are critical aspects of animal husbandry. It is essential to consider that different species of animals can show different vulnerability to trace elements, and therefore, it is necessary to ensure the correct balance of trace elements in the diet of each species of animal to preserve their health and productivity. This article describes the feeding of deficient trace elements and their chelated compounds (Fe, Cu, Mn, Co, Zn). The research aimed to investigate the content of microelements (Cu, Pb, Mn, Co, Zn, Cd, Ni, Fe) in the blood of young cattle after correcting diets with deficient microelements. The obtained results show that the level of trace elements increased slightly in the animals of the 2nd, 3rd, and especially the 4th experimental group. Thus, at the end of the experiment, the content of trace elements in the cattle of the experimental groups was higher than in the animals of the control group. The highest amount of trace elements in the blood was observed in the fourth experimental group, which was fed chelated compounds of trace elements (methionates) in the following doses: CuMet(0.05), MnMet(0.1), ZnMet(0.1), FeMet(0.05), CoMet(0.03) mg/kg body weight.

Published: November 2023

Food fortification is one of the most important processes for improving the nutritional quality and quantity of food products. Currently, the development of new recipes for dairy products is one of the driving forces of the dairy industry. The purpose of this study was to determine the suitability of the developed hard cheese with flax seeds for storage under the conditions defined by the standard. Microbiological studies were performed according to standard methods, which included the preparation of samples for the study, carrying out tenfold dilutions and sowing them on selective and storage media. Coliform bacteria and lactic acid microorganisms were determined according to DSTU 7357:2013, Salmonella and Listeria bacteria according to DSTU EN 12824:2004 and DSTU ISO 11290-1:2003, respectively. The developed Gouda-type hard cheese with flax seeds showed high microbiological indicators, which characterize its safety and quality, during storage at the temperature regime t... +5 ± 1 °C for 45 days. In particular, according to the amount of coliform bacteria, the product during 45 days of storage had a titer one order of magnitude higher than the maximum allowable limit (0.01 g), and according to the content of Staphylococcus aureus, it had an amount almost 20 times lower than the maximum allowable standard. Pathogenic microorganisms such as L. monocytogenes and Salmonella spp. were not detected in 25 g of the product during the entire storage period. At the end of the storage period, the number of lactic acid bacteria in the cheese was 8.0 ± 0.1 × 108 CFU/g. Therefore, the hard rennet cheese with flax seeds developed by us should show functional properties, both due to the content of flax seeds – a source of omega-3 fatty acids, and due to the vital activity of lactic acid microflora.

Introduction. In the course of time and due to the development of science and technology, the understanding of the effective university foreign language classroom has changed. The most significant change took place during the pandemic when all the students had to attend online classes. Nevertheless, our assumption is that in view of the nature of the subject itself, teaching and learning languages either online or offline to science or humanitarian majors has common characteristics relevant to any type of the classroom. It has specific characteristics related to different educational traditions, ethnic cultures, learning environments, and primarily to the agents (both teachers and students) involved in the process. The purpose of this article is to explore what ideas are frequently proposed by researchers worldwide and their implementation in university foreign language classrooms in Russia and China both in online and offline types of teaching and learning. Materials and methods. The study involved 61 university teachers of foreign languages from Russia and China who answered the questions of the questionnaire. A combination of both qualitative and quantitative methods of action research was used in the study. The methods included a literature review, the development of teacher questionnaires, a comparative study, data analysis and data visualization. Results. The study has revealed the major trends that are apparent in university foreign language teaching and learning both online and offline. They are related to learner-centered (60% of Chinese teachers / 23% of Russian teachers), interactive (15% of Chinese teachers / 30% of Russian teachers) and fostering learners’ engagement (55% of Chinese teachers / 25% of Russian teachers) with an emphasis on the development of overall students` communication, social and thinking abilities (100% of Chinese teachers / 95% of Russian teachers). Among the didactic tools used by foreign language teachers in both countries interactive tasks are prevalent with 95% и 100% of the Chinese and Russian teachers choosing them respectively. Conclusion. The differences revealed during the study need further research due to a limited number of the teacher participants. The conclusions obtained in this study will help to understand the main trends in modern foreign language teaching and learning, and assist foreign language teachers in choosing appropriate classroom techniques for their practices in line with more specific aims and content.

Dubovitskaya, 2010), Questionnaire "The resilient of an adult" (A. V. Makhnach, 2013). Research results. Qualitative and quantitative analysis helped to distribute students into three groups with different levels of adaptation to the educational environment of the university. So, 20% of students are adapted at a high level; 65.16% - at the average level; 14.84% - at a low level. Every fourth student is resilient (25.81%). They have the potential to deal with difficult life situations, as well as for self-development and personal growth. Every sixth (18.06%) has low hardiness, and slightly more than half (56.13%) has moderate hardiness. A correlation study showed that the higher the resilience of students, the higher their adaptability, acceptance of themselves and others, emotional comfort, internality, motivation "acquisition of knowledge" (r = .363; p < 0.05; r = .358; p < 0 .05; r = .670; p < 0.01; r = .630; p < 0.01; r = .521; p < 0.01; r = .683; p < 0.01). Conclusion. The resilient of students is associated with the successful adaptation of students. Viable students are highly satisfied with the social position in the student group, the effectiveness of their educational activities; emotional comfort; acceptance of self and others; infernality and activity; the motive of obtaining knowledge. Purposeful psychological work to improve the resilient of students will contribute to their successful social and psychological adaptation

Introduction. As China enters the aging population society, there is a higher demand for the quantity and quality of elderly care services, and further triggers the continuous demand for elderly care service talents in China. Some Chinese higher vocational colleges have set up majors in elderly care service management, and continuously transfer students to elderly care service institutions, but the mobility is still relatively high by survey. In this case, analyzing the factors affecting interns’ retention has become a major issue. Study participants and methods. Students who majored in elderly care services at a local higher vocational college in Wenzhou, China, and had internship experience in nursing institutions were chosen as the study's subjects. Students must complete an 8-month internship program, which includes a post-internship and a graduation internship. Non-probability sampling was utilized to extract the sample. For the questionnaire survey on internship duration, 100 higher vocational graduate students majoring in elderly care services were chosen, and 15 interns were chosen for interviews., and then they were analyzed using a qualitative comparative analysis method (QCA). Results. The analysis results for QCA: The personal psychological capital of the interns was the first core factor in any case. At the same time, even if there was no family support and high workload factors, the interns could stay as long as they can get a satisfactory internship salary and satisfactory accommodation & diet; Or even if there was no satisfactory internship salary and satisfactory accommodation & diet factors, as long as they had family support and low workload design, interns also could stay. While according to the data survey, 67% of students did not finish their internships, and 37% of those students departed their positions before the mandatory four months had passed. This is sufficient evidence that internship retention rates are quite poor among higher vocational students in China who major in senior care services. Practical significance. Good psychological capital, family support, and a moderate workload were all necessary for the internship to be successful. The internship requires an environment that cater the full supports intern. The ministry human resource management, needs to play a significant role in enforcing the policy to monitor the system that supports the internship process, ensuring that the business community is informed about internship-related concerns, and support the internship support system.

Problem and objective. In the current situation of intensive and forced use of information technologies and teaching tools in higher education, there is a problem of developing personality-developing forms and methods of using these technologies in the practice of university training. The aim of the study is to present and implement the methods of applying information technology, activating the personal potential of students. Research methods. The conceptual design of the study was based on person-centered didactic and psychological approaches and methods. The experimental work involved 58 students and 10 teachers of the Belgorod National Research University and the Belgorod State Technological University named after V.G. Shukhov. Diagnostic monitoring used methods of psychological testing: Questionnaire of motivational orientation (T. Amabile scale), Hardiness Survey (adaptation of S. Maddi test), General Self-Efficacy Scale (GSE), Self-organization Questionnaire, Purpose-in-Life Test (PIL). Statistical data processing included methods of parametric statistics and analysis of the significance of differences (Student's t-test). Results of the study. The authors have developed and put into practice a set of methods for stimulating the personal potential of students using information technology. The corpus of these methods included author's innovations (method of microsocial learning network), as well as modifications of a number of developing methods: dialogue, imaginative, case, game, quest, command-network. The application of these methods in practice has shown their sufficient promise. According to psychological monitoring data, the students of the experimental group have an increase in intrinsic motivation (tEMP = 2,7); there is an increase hardiness (tEMP = 4,7) due to higher involvement in the life process (tEMP = 2,8) and readiness for risk (tEMP = 3,3); confidence in self-efficacy grows (tEMP = 1,2), indicators of self-organization of activity increase: purposefulness (tEMP = 5,2), perseverance (tEMP = 4,6), ability to plan (tEMP = 2,7); there is a higher sense of meaningfulness of life (tEMP = 4,5) due to an increase in interest in life as a process (tEMP = 5,1) and life productivity in terms of self-realization (tEMP = 3,2). Conclusion. The methods of using information technologies in education presented in the study have no exact analogues in contemporary researches. Their uniqueness lies in the indirect use of these technologies as tools of personalizing educational communications. The complex application of the proposed methods makes it possible to introduce information technologies to stimulate students' activity as subjects of full-fledged learning activities in the context of digitalization, which is the practical significance of the work done.
