Authors: Liu Jiaqi
Published: December 2024

This paper systematically describes the design and optimisation strategy of wireless charging technology for implantable medical devices. Starting from the theoretical basis of magnetically coupled resonant wireless power transmission (MCR-WPT), an efficient transmission circuit is designed and the resonant circuit characteristics are analysed. Meanwhile, the effects of the outer diameter, the number of turns of the transmitting coil and the turns spacing on the magnetic flux density and the AC internal resistance are obtained through the principle analysis. The coil parameters are adjusted through simulation experiments to improve the transmission efficiency. Then, the safety and stability of the device are ensured by temperature-power double closed-loop control. Then the closed-loop phase-shift control strategy is introduced to ensure that the system can output power stably in complex environments. In this paper, a low-power, safe and high-efficiency wireless energy transmission system is built, which provides a comprehensive and in-depth technical reference for the development of wireless power supply technology for implantable medical devices.

Major clinical findings on the types of impressions used in implant-supported prostheses: a systematic review
Authors: Martinez Ygor Souza , Moreira Janaína Cardoso
Published: December 2024

Introduction: The key to obtaining perfect prostheses depends on the passive fit between its connector and the implant itself. The compromised fit between the contact surfaces of implant-supported prostheses creates uncontrolled stresses in the components and peri-implant tissues, evoking biological and mechanical complications. Objective: It was to review the scientific literature on the types of impression used in implant prostheses. Methods: The PRISMA Platform systematic review rules were followed. The search was carried out from July to August 2024 in the Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 111 articles were found, and 44 articles were evaluated in full, and 23 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 06 studies with a high risk of bias and 31 studies that did not meet GRADE. Minimizing contraction appears to be the most important factor in ensuring an accurate impression for this technique. Digital printing has achieved high patient acceptance, reduces possible impression and master mold errors, reduces time in the chair, provides a three-dimensional image of the preparation, and ease of communication between the clinician and the laboratory. However, there is a dearth of scientific data regarding implant fingerprints and their accuracy. Research on implant fingerprinting has been limited to a few in vitro studies and case reports.
Predicting sustainability for slowtourism events
Authors: Angelaccio Michele , Zappitelli Lucia
Published: December 2024

The increasing demand for slow tourism in rural regions is leading many organizations to reorganize events by planning new strategies able to predict the impact of incoming visitors and new stakeholders. Typical economic benefit-cost analysis often cannot be used in such contexts in which it is hard to predict socio-economic impacts that are the most relevant. In this way, a methodology like the SROI Method, based on a wide set of indicators and a flexible analytical method, could give a prediction estimation useful to predict socio-economic impacts and tailored for a wide set of people. In this paper we consider three examples taken from small villages around Rome for which a set of events has been analyzed through a revised SROI Method in which we calculate the corresponding SROI value and compare it under a set of revised stages named as—SMARTOUR SROI focused on Slow Tourism Planning. The proposed evaluation methodology obtained by the application of the SROI Method to smart tourism stages is a first example of new sustainable analysis for slow tourism. The result shows that the methodology always gives a positive evaluation by highlighting the main issues related to the impact of slow tourism in such emerging scenarios. Moreover, in the discussion we can show that the case of the historical train example gives the best result due to the particular impact of such a typical scenario.

This study examined the nexus between monetary policy and sustainable development goals number ten in Nigeria from (1987 to 2022). The data for this study were collected from secondary sources, which include World Bank and World Development Indicator online data base, previous studies, as well as journals articles. The estimation techniques used for this study were econometrics tools to run the regression, unit root test, ARDL, Bound Test, and granger causality tests. The results from the study showed that there is combination of I (1) and I (0) among the variables based on the stationarity test conducted. The ARDL test result shows that there is existing of long relationship through the bound test, of F-statistics 5.63 at 10 and 5 per cent respectively. The granger causality test indicated bidirectional causality and no causality relationship among the variables. The results of the short run and long run indicated that the monetary policy has both positive and negative impacts on SDG-10 in Nigeria. The study recommends that the government should consider the inflationary and exchange rates in Nigeria in order to tackle the level of inequality among the citizens. This can be effectively carried out through a stringent price control for goods and services as well as implementing a fixed exchange rate policy that would restrict the ever-declining value of naira relative to dollar exchange rate. If effectively articulated, it will ensure equitable distribution of income and wealth among the citizens in the country. The major scientific novelty introduced in this study is the measurement of inequality using Gini Coefficients based on SDG-10 perspective.

The increasing emergence of bacterial resistance against antibiotics or antibacterial drugs has challenged the development of antibacterial agents like nanoparticles which have received increased attention due to their antibacterial activity against pathogenic bacteria. In this investigation, zinc oxide, copper oxide, and silver (ZnO, CuO, and Ag) nanoparticles were chemically synthesized by sol-gel, wet chemical precipitation, and chemical reduction procedures, respectively. Characterization of nanoparticles was performed using UV-Visible and Fourier-Transform Infrared (FTIR) spectroscopy. Antibacterial activity of nanoparticles was analyzed against Staphylococcus aureus and Salmonella typhi. UV-Visible spectroscopy of ZnO, CuO, and Ag nanoparticles showed peaks at 375, 225, and 400 nm, respectively, and indicated optical properties of the nanoparticles, thereby confirming their formation. FTIR analysis showed presence of Zn-O and Cu-O bonds in ZnO and CuO nanoparticles, respectively, and various functional groups in Ag NPs. Antibacterial studies conducted against S. aureus and S. typhi reflected no antibacterial activity by ZnO and CuO nanoparticles individually, while Ag NPs showed good antibacterial effects against both pathogenic bacteria. Additionally, the antibacterial activity of ciprofloxacin impregnated with Ag NPs against S. aureus showed a synergistic effect.

Authors:   JSW Steel Limited, Toranagallu, Bellary, India, Mohapatra J.N. , Satish Kumar D. ,   JSW Steel Limited, Toranagallu, Bellary, India
Published: December 2024

In this study hot-rolled (HR) 2.8 mm thick DP980 steel was water quenched (WQ) in laboratory from various temperatures to simulate welding-induced microstructures. The HR and WQ (925◦C) samples were tempered in the temperature range 200–600◦C to study the temper-induced changes in microstructure, mechanical properties, and their correlation with the magnetic properties. Microhardness, yield strength, and ultimate tensile strength of the steels were increased along with the coercivity while ductility, remanence and maximum inductions were decreased with increase in austenitization temperature for the enhancement of martensites. A reversing trend in the above properties was found with increase in tempering temperature due to the softening of the steel. However, the decreases in the properties were higher at the higher tempering temperatures in WQ samples compared to the HR samples for the stress relaxation in the steel due to reduction in density of dislocations produced during water quenching and softening of martensites.

Published: December 2024

The COVID-19 pandemic, which emerged as a global health crisis, catalyzed diverse responses, including the integration of traditional medicine (TM) systems. The prevention and control of COVID-19 is examined in this study in relation to Sinhala medicine, a well-known TM system in Sri Lanka. TM in Sri Lanka is a valuable medical system that has been developed from the social culture and experience of the people of Sri Lanka, which has a long history. From the past to the present, a great contribution has been made in managing various health challenges in Sri Lanka through this TM system. Among health challenges, the epidemic is a condition that causes small to large-scale disasters. The main research question of the study is What is the role and treatment of Sinhala medicine in the face of the COVID-19 pandemic? The main research objectives are to document the traditional Sinhala medical treatments employed during the COVID-19 pandemic and to understand the cultural significance of these practices in preventing and controlling infectious diseases. As an exploratory research using the mixed method based on qualitative data and quantitative data, the Pragmatist paradigm was utilized by the researcher with a phenomenological research design. There, the study area covering the 03 districts of Colombo, Monaragala, and Anuradhapura was selected purposefully and 2 samples were selected from the study area as a sample of 15 traditional medicine practitioners and a sample of 60 elderly people over 50 years of age. The study revealed a number of treatments used in Sinhala medicine to prevent the COVID-19 pandemic, including medicines, dietary habits, disinfection techniques, rituals and social practices. This research uncovered a wealth of valuable knowledge about TM remedies under the ICH and TCH of Sri Lanka, while uncovering their new trends and functions in the present day. Considering the conclusions of the research, it appears that traditional medicine in Sri Lanka has adopted practices with rich knowledge about epidemic disease prevention and control and has improved them to suit modern society. Also, it was clear that the advice given in legal form regarding epidemics by modern medicine has been done in ritual form by TM since the past.

Published: December 2024

Although there are several frameworks for the synthesis of form, and for the automated development of geometric shapes, studies in the systematic analysis of architectural forms and their automation are still underrepresented. This paper describes a framework for computer-aided geometric form analysis. It illustrates the framework's applicability by an example from precedent architectural design. The form analysis framework is developed theoretically and further translated into a computer code that is written in the AutoLISP language to fit its graphic operation system. Application of the framework and its computerized code demonstrates its power as a promising analytical tool that can help designers analyze precedents' morphological structure more efficiently.

The MC states for this study were adopted from a previous one, based on performance brackets. The Markov chain displayed a satisfactory level of prediction for the probability of a university moving from one level to another. The distribution of university rankings could be well defined to determine the performance of a university.
Addressing Today's Software Risks Requires an Assurance-Educated Workforce
Authors: Woody Carol S.
Published: December 2024

There is a significant gap in the current acquisition and engineering workforce's knowledge, skills, and support resources needed to address software and supply chain risk. This gap is widened by two factors: the growing reliance on software to handle system functionality and the exponential increase in cyber attacks. These factors underscore the importance of ensuring that all acquisition software functions as intended and is free from vulnerabilities that can create or contribute to existing cybersecurity issues. However, acquirers, developers, program managers, systems engineers, and decision makers typically lack the knowledge required to create and comply with these requirements. Determining who should be trained and how they should be trained has been an ongoing discussion in the software community for several years. In this paper, we summarize the efforts currently underway to address gaps in workforce knowledge, skills, and support resources based on recent publications and panel discussions held by the Software Assurance Supply Chain (SSCA) forum.

Authors: Зибарева О. В.
Published: December 2024

Важливість теми дослідження полягає у зростаючій потребі забезпечення соціальної безпеки як на національному, так і на глобальному рівнях, особливо в умовах сучасних глобалізаційних викликів. Актуальність дослідження зумовлена необхідністю формування нових підходів до вирішення соціальних загроз у світі. Метою дослідження стало проаналізувати еволюцію концепції соціальної безпеки та окреслити основні тенденції її розвитку в національному і глобальному контекстах. Дослідження побудовано на міждисциплінарному підході із використанням історико-логічного, системного та порівняльного методів. Аналізується процес формування соціальної безпеки через призму історичних етапів, а також з огляду на сучасні тенденції глобалізації. Підхід передбачає системне вивчення факторів, що впливають на соціальну стабільність та їхню взаємодію на різних рівнях. Запропоновано гіпотезу, що глобалізація суттєво впливає на соціальну безпеку, трансформуючи її від національно-орієнтованої до багаторівневої концепції. Використано історико-логічний метод для виявлення етапів еволюції соціальної безпеки, порівняльний аналіз для зіставлення національних та глобальних підходів, а також методи аналізу та синтезу для систематизації даних. Прогностичний метод застосовано для визначення перспектив розвитку соціальної безпеки. У статті досліджено теоретичне та практичне співвідношення понять «соціальний захист», «соціальне забезпечення» та «соціальна безпека». Проаналізовано історичні передумови виникнення цих категорій та їх трансформацію в наукових і правових дискурсах. Наголошено на тому, що соціальний захист є ширшим поняттям, яке охоплює заходи підтримки вразливих верств населення через механізми соціального забезпечення. Окрему увагу приділено категорії «соціальна безпека», яка формується як стратегічний інструмент забезпечення стабільності та добробуту суспільства. Визначено три ключові рівні соціальної безпеки (державний, суспільний та індивідуальний), а також сучасні підходи до її вимірювання в контексті глобальних викликів ХХІ століття. Стаття розкриває зв'язок соціальних витрат з ВВП країн, демонструючи залежність стабільності суспільства від ефективної соціальної політики. Проведено порівняльний аналіз соціальних витрат у країнах ОЕСР, що підкреслює роль державних пріоритетів у забезпеченні соціального добробуту. Автор робить висновок про необхідність інтегрованого підходу до соціального захисту та безпеки як засобу мінімізації ризиків та досягнення соціальної гармонії.

Clarification of fire characteristics in a road tunnel based on numerical and laboratory studies
Authors: Lanchava Omar
Published: December 2024

Critical velocity for longitudinal ventilation, as is accepted under the emergency ventilation strategy, is a decisive factor to prevent backlayering. The results of physical and thorough numerical modeling showed that the critical velocity in inclined tunnels in case of descending ventilation and of strong fires would no longer be an important indicator within the projects. Besides, the location of the fire has a significant impact on the thermal physics and aerodynamics of the ventilation flow and the surrounding mining massif. A natural consequence of this is significant variation in critical velocity and backlayering length, which greatly affects the planning and implementation of life-saving measures. The article presents scenarios of underground fire development and analysis of accompanying processes, performed using numerical modeling in the FDS environment. The variation of the critical velocity of longitudinal ventilation, the length of the reverse flow of combustion products and the gradient-factor depending on the fire power, tunnel geometry and other variabilities is shown. It is noted that the critical value of the Froude number, like the critical ventilation rate, are not constant values in complex processes occurring underground. Specific numerical examples show that thermally and mechanically conditioned ventilation flows are algebraically summed, and without considering these circumstances, the processes of rescuing people from underground fires will certainly become more complicated. The paper found, both theoretically and through numerical modeling, that severe fires in tunnels can cause dynamic pressures greater than the static pressure of the fans. The observed dynamic pressures can reverse downward ventilation flows in tunnels with slopes of 3% or more. This work puts on the agenda not only a thorough detailed description and analysis of fire cases, but also the need to develop a clear algorithm of actions taking into consideration the geometry, location, natural conditions and ventilation systems of a specific tunnel, taking into consideration also the scenario of the expected fire. The results obtained should be communicated to rescuers and tunnel service workers through theoretical studies and training. The proposed paper is socially oriented, aimed at improving emergency ventilation technology and thus increasing safety in case of fires in road tunnels, which is an important socio-political and public task.

Appendicitis is one of the most common abdominal emergencies. Patients are usually presented with lower right abdominal pain, nausea, vomiting and fever. Acute appendicitis is a challenging clinical diagnosis, and patients with suspected appendicitis can be diagnosed by Ultrasound (US) or computed tomography (CT) according to the hospital protocol and patient clinical condition. The aim of this study is to investigate the value of CT in diagnosing suspected cases of acute appendicitis. Retrospective research to evaluate the role of CT scan in the diagnosis of acute appendicitis, based on data received from King Abdulaziz university hospital in Jeddah, from January 2017 to January 2022. A total of 204 patients (121 Males and 83 Females) ranging in age from 2 to 91 years presented with acute appendicitis were included. The collected data included age, gender, patients' complaints, medical history, laboratory tests, radiology reports, operations, and pathological results. The most prevalent age group was 10-30 years old. Most patients (77%) presented with typical appendicular pain, while (56%) presented with vomiting. CT was requested for 142 patients while 35 patients were referred to Ultrasound. Both modalities were done to 27 patients. The Commonest finding in CT scan was dilated appendix with sensitivity of 84% with 100% overall diagnostic sensitivity. CT is a sensitive tool used to diagnose acute appendicitis and its complications. It is recommended to be used as the primary imaging modality in cases of acute appendicitis.
Nghiên cứu tác động các yếu tố dinh dưỡng đất tới sự phân bố của cây Bò khai (Erythropalum scandens Blume) tại huyện Võ Nhai, tỉnh Thái Nguyên

Cây Bò khai có tên khoa học là Erythropalum scandens Blume. Trong dân gian cây Bò khai được coi là loại rau vừa có tác dụng làm thực phẩm, vừa có tác dụng làm thuốc chữa bệnh. Cây Bò khai được “thuần hóa” trở thành cây hàng hóa và được nhân giống tại nhiều địa phương trên cả nước trong đó có tỉnh Thái Nguyên. Tuy nhiên cây Bò khai xuất hiện trong tự nhiên đang có xu hướng giảm dần, nguyên nhân có thể do môi trường tự nhiên thay đổi đã làm thu hẹp vùng phân bố hoặc do tình trạng khai thác quá mức của con người. Để phát triển vùng trồng cây Bò khai, nghiên cứu đã tiến hành đánh giá mối tương quan giữa yếu tố dinh dưỡng đất và sự phân bố của cây Bò khai tại khu vực Khu bảo tồn thiên nhiên (KBTTN) Thần Sa - Phượng Hoàng, huyện Võ Nhai, tỉnh Thái Nguyên. Nghiên cứu sử dụng phương pháp phân tích mẫu đất tại các ô tiêu chuẩn và phương pháp phân tích thành phần chính (PCA) bằng phần mềm thống kê PRIMER5. Kết quả nghiên cứu chỉ ra cây Bò khai có mức độ tương quan cao nhất với tỷ lệ phần trăm Ca (%) trong đất, tiếp đến là nitơ, mùn, lân, kali tổng số và pHKCl. Trong khi đó, ở ngoài tự nhiên sự xuất hiện của cây Bò khai tại huyện Võ Nhai, tỉnh Thái Nguyên thường ở những vị trí trên cao, đất có tỉ lệ đá lẫn nhiều, độ tàn che khá, ít xuất hiện ở những trạng thái rừng giàu. Điều này phù hợp với sự xuất hiện của cây Bò khai tương quan rất chặt nhưng ngược chiều với một số yếu tố như trạng thái rừng, màu sắc đất và tỷ lệ rễ cây trong đất.

Đăng ký đất đai theo mô hình phi địa giới hành chính đã được áp dụng ở tỉnh Đồng Nai từ năm 2017. Mục đích của nghiên cứu là đánh giá kết quả chuyển nhượng, tặng cho, thế chấp, xóa thế chấp quyền sử dụng đất theo mô hình phi địa giới. Nghiên cứu đã phỏng vấn 100 người sử dụng đất nộp hồ sơ tại Văn phòng đăng kí (VPĐK) tỉnh Đồng Nai; phỏng vấn 50 lãnh đạo và cán bộ chuyên môn thuộc Văn phòng Đăng ký đất đai, cơ quan thuế; sử dụng thang đo Likert 5 cấp để đánh giá. Kết quả nghiên cứu cho thấy tỷ lệ hồ sơ đăng ký chuyển nhượng, tặng cho chiếm tỷ lệ cao và dao động từ 42,59 - 48,83% so với tổng số hồ sơ chuyển nhượng, tặng cho; giao dịch thế chấp, xóa thế chấp chỉ chiếm từ 14,76 - 24,58% so với tổng số giao dịch thế chấp, xóa thế chấp trên địa bàn toàn tỉnh. Số lượng và tỷ lệ % hồ sơ thực hiện mô hình phi địa giới có xu hướng tăng trong giai đoạn 2019-2022. Người dân thực sự đã quan tâm và đánh giá rất cao mô hình này do rất dễ tiếp cận dịch vụ, cơ sở vật chất rất tốt, rất dễ thực hiện thủ tục, rất hài lòng với cán bộ tiếp nhận hồ sơ và sự phối hợp rất tốt với các bên liên quan. Chất lượng hệ thống hồ sơ địa chính được cán bộ đánh giá là có sự ảnh hưởng rất lớn tới hoạt động đăng ký phi địa giới hành chính. Nghiên cứu chưa đánh giá tác động của mô hình phi địa giới tới hoạt động của các chi nhánh VPĐK cấp huyện.

Paddy fields in the northern part of Turkey are concentrated in the Bafra Plain in Mid-Black Sea region, where the highest wheat and leguminous production is performed. Turkey's longest river, Kızılırmak, flows into the Bafra plain. For this reason, it can be said that the most fertile lands in our country are in Bafra Plain and its surroundings. The aim of the present study is to determine the awareness of paddy producers located in the Bafra Plain about smart agriculture applications. A field survey has been conducted at the plain and the results were analyzed. Interviews were conducted in September 2024 with a total of 150 participants coming from different villages. 44% of farmers had more than 100 da paddy field each. At the end of the research some striking results were obtained. The level of awareness along with their reasons were determined. Awareness of smart agricultural tools was low at all. But, hopefully (3.3%) of farmers declared that the smart agriculture practices is and will keep on being important for the future in rice farming.
