Authors: Vargas F. , López M.E. , Ageorges H. , Fauchais P.
Published: December 2022

In the present work, the effect of coating toughness on the wear resistance of alumina-titania coatings was studied. Two parameters were modified: Al2O3-TiO2 ratio and particle size distribution. Coatings were obtained by atmospheric plasma spraying on a carbon steel disc. Coating toughness was measured by indentation tests, while wear resistance was determined by ball-on-disc measurements. The results show that coatings with higher toughness exhibit better wear resistance.

Objective of the Paper: To draw the attention of pediatricians, otorhinolaryngologists, general practitioners to the possibilities of irrigation therapy in the treatment of acute respiratory viral infections in children. Key points. Irrigation therapy is widely used for the prevention and treatment of acute infections of the upper respiratory tract in children, and is an effective and safe method. However, there are no indications in the clinical guidelines about the exact concentrations of saline solutions, the method of irrigation therapy, and its duration. For use in acute respiratory viral infections in children at different periods of the disease, it is preferable to use a slightly hypertonic solution of sea water in the form of a fine spray. In the acute period, irrigation therapy reduces the need for the use of decongestants and antibiotics. In the subacute and post-viral periods, it promotes the regeneration of the ciliary epithelium. Conclusion. The addition of Ascophyllum nodosum brown algae extract to solutions for irrigation therapy can increase the effectiveness of treatment, promote faster relief of inflammation in the nasal cavity, and restore the mucosa due to the anti-inflammatory, antimicrobial, and immunomodulatory properties of fucoidans. Keywords: acute respiratory viral infections, irrigation therapy, children, sea water, brown algae.

Purpose: quality assessment of hydrometric conditions for attracting anad-romous fish migratory along the river Western Manych in the fish passage channels of the Ust-Manych waterworks. Materials and methods. The factual basis of the study was the data of hydrological surveys carried out on the Ust-Manych fish passage channels, designed to allow fish spawners to pass to their spawning grounds. Generally accepted methods and techniques were used while conducting surveys, processing experimental data, their analysis and generalization. Results and discussion. Data have been obtained and calculations of hydrological characteristics have been made in the sections of the river Western Manych, corresponding to the location of the entrances to the fish channels, for two and three-month periods of the spring-summer spawning run of migratory fish. Differences in the values of water levels in the downstream of the Ust-Manych waterworks depending on the duration of the observation period were determined. Experimental data and calculated dependences to determine the average flow rates in the control sections for a wide range of changes in flow rates and water levels were obtained. The determined hydrological data of the river and the hydrometric data of fish passage channels constituted an empirical basis for assessing the quality of conditions for attracting fish from the river Western Manych to the entrances to the canals. It has been found that the quality indicator of conditions at different ratios of the values of the factors of influence for one fish passage channel was 27.3–45.3 %, and for the second channel it varies within 15.1–21.6 %. Conclusions. Data were obtained on hydrological values characterizing the section of the river Western Manych from the Ust-Manych waterworks to the alignment of its confluence with the river Don. An assessment of the hydrometric conditions quality for attracting fish migrating along the river to spawning grounds at the entrances to fish passage channels is made.

«Внедрение в мазунинскую культуру тураевско-харинских групп»: к дефиниции типов
Authors:   Удмуртский федеральный исследовательский центр Уральского отделения РАН, Красноперов Александр
Published: December 2022

Формулировка проблемы объединяет три самостоятельных блока. «Классический» ха-ринский культурный комплекс представлен находками в подкурганных погребениях поясной гарниту-ры, обильно украшенной зернью. Датируется VI в. Группы разделены территориально, но разделение на самостоятельные археологические культуры нецелесообразно. Культурные отличия становятся суще-ственно заметны только в после-харинское время. Во всех ареалах (Коми Республика, Пермский край, Удмуртия) харинские древности развиваются на гляденовской основе. Можно говорить о выделении двух более ранних этапов V в. и последней четверти IV– начала – первой половины V в. Тураевские курганы представляют собой изолированное явление в Прикамье. Типологические связи материалов ограничены перечнем из примерно десяти комплексов. Хронологически они синхронны самым ранним пред-пред-харинским комплексам, но реальной связи между Тураевскими курганами и харинскими мо-гильниками нет. Мазунинская культура в «классическом» виде прекращает существование во второй по-ловине IV в. В конце IV в. перестают совершаться погребения на всех могильниках к северу от р. Камы и на большинстве могильников к югу от нее. Территория запустевает. Мазунинские «этнографические» элементы с материалами V в. изучены только на Бирском и Бахмутинском могильниках в сочетании с керамикой «чандарского» типа. Хронология появления новых керамических групп пока не ясна. Факти-чески, мазунинская культура заканчивается до совершения первых погребений в Тураевских курганах и в харинских могильниках.

В статье впервые публикуются и анализируются материалы, полученные при исследо-вании венгерского погребения 3 кургана 7 группы «ДОТ» у с. Глиное Слободзейского района на левобе-режье Нижнего Днестра. Захоронение было совершено в прямоугольной яме возле юго-восточной полы насыпи. Костяк лежал в вытянутом положении на спине, головой на запад-юго-запад. У левого плеча находилась левая плечевая кость овцы. Подобный обряд зафиксирован не только в венгерских могилах Северного Причерноморья, но и восточнее – в Подонье, в Поволжье и на Урале. В качестве жертвенных животных венгры использовали не только овец, но и лошадей, а также крупный рогатый скот. В ногах была поставлена деревянная колода. У левого колена был найден железный нож, у левой стопы – желез-ная пластина. Поверх левого крыла таза лежали две серединные костяные накладки от лука. На правой лучевой кости располагались остатки колчана в виде пяти железных наконечников стрел и железного шила. Под правым запястьем, у крыла таза, зафиксированы фрагменты железного кресала и кресальный кремень. Аналогии наконечникам стрел, а также радиоуглеродные даты позволяют датировать захоро-нение концом IX– первой половиной X вв. Это погребение, вместе с ранее исследованными на левобе-режье Нижнего Днестра венгерскими могилами, позволяет фиксировать пребывание венгров в регионе с середины IXпо середину X вв.
Paradise of Wisdom

Published: December 2022

Antique traditional medical theories created by old medical doctrines and their historical background have been significantly mentioned today by medical historian scholars. Persia and India had many interactions in different perspectives, such as knowledge, religion, and traditions. One of the most considerable aspects of the relationship between Indians and Persians is the transmission of basic theories of their medical doctrines. As it is reported in many historical texts from the first ages of the Islamic era in Iran, a large number of medical texts were gathered from contiguous civilizations in Iran by order of the Abbasid Caliph. They were then translated into Arabic, Syriac, and Persian. So, Persian physicians and authors used them that way. One of the earlier physicians who reflected the viewpoints of Indian medicine in his famous medical textbook entitled “Paradise of Wisdom” is Ali ibn Sahl Rabban al-Tabari (3rd century A.H./9th century A.D.). Persian physicians in the Islamic golden age (8th to 16th A.D.) played an astonishing role in the development of medical knowledge in several aspects through physician innovations and expression and evaluation of different ideas about medicine. In this regard, some of the Indian medical theories were expressed by a famous Persian physician, Ali ibn Sahl Rabban al-Tabari. Ali ibn Sahl Rabban al-Tabari was a Persian physician of the 3rd century A.H./9th century A.D. He wrote the book Firdous al-Hikmah (or Paradise of Wisdom), the first encyclopedia of Islamic medicine in Iran. The book introduces and describes the basics and therapeutic procedures adopted in Indian medicine, along with procedures of Persian and Greek medical doctrines, by discussing the basic medical theories in these three doctrines. In this paper, we discuss the reflection of traditional Indian medicine as described in Firdous alHikmah and its influence on later medical texts.

Published: December 2022

BACKGROUND: Pole vaulting involves trunk flexion, extension, and rotation, which may place the lumbar spine under stress. Repeated pole vaulting may cause lumbar disc degeneration (DD) and lumbar spondylolysis (LS); however, this phenomenon is yet to be established. OBJECTIVE: This study aimed to determine the difference in the maximum joint angles of the shoulder, hip, and trunk during pole vaulting between male pole vaulters with and without lumbar DD or LS. METHODS: This retrospective study included 17 male pole vaulters. Four high-speed cameras were used to record the pole vaulters at 240 Hz. Radiography and magnetic resonance imaging were used to examine the lumbar spine in all athletes. Differences in the data between two sets of groups were analyzed using the unpaired t-test or the Mann-Whitney U test. RESULTS: There was a significant difference in the maximum joint angle of hip flexion between pole vaulters with and without lumbar DD (p= 0.03). CONCLUSION: Pole vaulters with lumbar DD may use lumbar flexion instead of hip flexion during the rock-back movement. Moreover, LS may occur due to repeated failed vaulting. Therefore, trunk stability and functional movements should be prioritized to prevent organic changes in the lower back.

Published: December 2022

BACKGROUND: There is a sex-related difference in strength and endurance in trunk muscles: males have more strength while females have more endurance. OBJECTIVE: Investigate sex-related differences in motor control strategies in back muscles during isometric contractions (IC) in the Sorensen test posture. METHODS: Thirty-six healthy and young volunteers performed different tasks: three maximal voluntary contraction (MVC) tests recorded with a bio-feedback force sensor, and followed by five loaded IC (LIC) tests using bodyweight and loads of 0 to 8 kg with a 2-kg step. Surface electromyography was used to measure the activity of bilateral lumbar paravertebral (LP) and quadratus lumborum (QL) muscles. RESULTS: Sex-related and load-related differences in EMG amplitudes were highlighted during LIC tests. Females showed significantly (p-value = 0.02) greater EMG amplitude for the highest load (8 kg) than males. Besides, significant differences between low (2 and 4 kg) and high (6 and 8 kg) loads for both LP and QL muscles and for both sexes were observed. Finally, for MVC tests, males produced significantly (p-value = 1.02e-4) greater strength during MVC tests (4.25 ± 1.37 N/kg vs 2.60 ± 0.78 N/kg). CONCLUSION: The results were clinically relevant to bring attention to load strategy during rehabilitation, particularly in females who seemed to recruit the QL muscle more.

Authors: Bhimavarapu Usharani , Sreedevi M.
Published: December 2022

Fine particulate matter (PM2.5) is one of the major air pollutants and is an important parameter for measuring air quality levels. High concentrations of PM2.5 show its impact on human health, the environment, and climate change. An accurate prediction of fine particulate matter (PM2.5) is significant to air pollution detection, environmental management, human health, and social development. The primary approach is to boost the forecast performance by reducing the error in the deep learning model. So, there is a need to propose an enhanced loss function (ELF) to decrease the error and improve the accurate prediction of daily PM2.5 concentrations. This paper proposes the ELF in CTLSTM (Chi-Square test Long Short Term Memory) to improve the PM2.5 forecast. The ELF in the CTLSTM model gives more accurate results than the standard forecast models and other state-of-the-art deep learning techniques. The proposed ELFCTLSTM reduces the prediction error of by a maximum of 10 to 25 percent than the state-of-the-art deep learning models.

Published: December 2022

The traditional healthcare systems require more data storage and not a quick responsive mode. The new era of intelligent healthcare systems uses advanced frameworks and devices to work with Internet of things (IoT), Cloud Computing, edge computing devices, and the Internet of Medical Things (IoMT). These technology adoptions may drastically increase healthcare systems performance and are available anytime and anywhere to replace traditional medical methods – the organizations in the network exchange the patient data that has been gathered. The healthcare systems are therefore susceptible to a variety of threats. The attacker may exploit many attacks during the transmission. This paper introduces a novel mechanism of A Secure Robust Privacy-Preserving Authentication and Key Agreement Framework for Mobile Healthcare Applications. The proposed framework collects the patient’s data using wearable devices called sensors, and the collected data is shared with various entities using a secure mechanism. The proposed framework uses Elliptic Curve Cryptography (ECC). Digital sign is created and validated through the Elliptic Curve Digital Signature Algorithm (ECDSA). Security properties of the proposed framework are analyzed through standard model checking tool Automated Validation of Internet Security Protocols (AVISPA). The suggested protocol is simple to develop and can withstand network-related threats.

Authors: Yenkikar Anuradha , Babu C. Narendra
Published: December 2022

Airlines operate in a competitive marketplace and must upgrade their services to meet customer safety and comfort. Post-pandemic, the government and airlines resumed flights with many restrictions, the impact which is unexplored. An increasing number of customers use social media to leave reviews and in this age of Machine Learning (ML), if a model is available to automatically polarize flyer sentiments, it can help airlines upscale. In this work, a custom dataset is scraped from Twitter by including online reviews of five Indian airlines. Multiclass sentiment analysis using three classifiers, support vector machine, K-nearest neighbor and random forest with word2vec and TF-IDF word embeddings is implemented. AirBERT, a fine-tuned deep learning attention model based on bidirectional encoder representation from transformers is proposed. From results, it is observed that on ML, Random Forest with TF-IDF performs the best but the graphical processing unit and domain corpora trained AirBERT outperforms all the other models with an accuracy of 91%. Indigo airlines and Jet Airways received the maximum percentage of positive and negative reviews respectively. In performance comparison with three existing models on the USA airlines tweets dataset, the proposed model outperforms others trained on general domain corpora and matches state-of-the-art TweetBERTv2 model accuracy. The model can be deployed by airlines and other service industries to implement a customer relationship management (CRM) system.

Published: December 2022

A Computer Aided Diagnosis (CAD) framework to diagnose Pulmonary Edema (PE) and covid-19 from the chest Computed Tomography (CT) slices were developed and implemented in this work. The lung tissues have been segmented using Otsu’s thresholding method. The Regions of Interest (ROI) considered in this work were edema lesions and covid-19 lesions. For each ROI, the edema lesions and covid-19 lesions were elucidated by an expert radiologist, followed by texture and shape extraction. The extracted features were stored as feature vectors. The feature vectors were split into train and test set in the ratio of 80 : 20. A wrapper based feature selection approach using Squirrel Search Algorithm (SSA) with the Support Vector Machine (SVM) classifier’s accuracy as the fitness function was used to select the optimal features. The selected features were trained using the Back Propagation Neural Network (BPNN) classifier. This framework was tested on a real-time PE and covid-19 dataset. The BPNN classifier’s accuracy with SSA yielded 88.02%, whereas, without SSA it yielded 83.80%. Statistical analysis, namely Wilcoxon’s test, Kendall’s Rank Correlation Coefficient test and Mann Whitney U test were performed, which indicates that the proposed method has a significant impact on the accuracy, sensitivity and specificity of the novel dataset considered. Comparative experimentations of the proposed system with existing benchmark ML classifiers, namely Cat Boost, Ada Boost, XGBoost, RBF SVM, Poly SVM, Sigmoid SVM and Linear SVM classifiers demonstrate that the proposed system outperforms the benchmark classifiers’ results.
An efficient multilevel thresholding segmentation method based on improved chimp optimization algorithm
Authors: Fu Xue , Zhu Liangkuan , Wu Bowen , Wang Jingyu , Zhao Xiaohan , Ryspayev Arystan
Published: December 2022

To improve the traditional image segmentation, an efficient multilevel thresholding segmentation method based on improved Chimp Optimization Algorithm (IChOA) is developed in this paper. Kapur entropy is utilized as the objective function. The best threshold values for RGB images’ three channels are found using IChOA. Meanwhile, several strategies are introduced including population initialization strategy combining with Gaussian chaos and opposition-based learning, the position update mechanism of particle swarm algorithm (PSO), the Gaussian-Cauchy mutation and the adaptive nonlinear strategy. These methods enable the IChOA to raise the diversity of the population and enhance both the exploration and exploitation. Additionally, the search ability, accuracy and stability of IChOA have been significantly enhanced. To prove the superiority of the IChOA based multilevel thresholding segmentation method, a comparison experiment is conducted between IChOA and 5 six meta-heuristic algorithms using 12 test functions, which fully demonstrate that IChOA can obtain high-quality solutions and almost does not suffer from premature convergence. Furthermore, by using 10 standard test images the IChOA-based multilevel thresholding image segmentation method is compared with other peers and evaluated the segmentation results using 5 evaluation indicators with the average fitness value, PSNR, SSIM, FSIM and computational time. The experimental results reveal that the presented IChOA-based multilevel thresholding image segmentation method has tremendous potential to be utilized as an image segmentation method for color images because it can be an effective swarm intelligence optimization method that can maintain a delicate balance during the segmentation process of color images.
Patient Reported Outcome Measures in Adult Spinal Muscular Atrophy: A Scoping Review and Graphical Visualization of the Evidence
Authors: Slayter Jeremy , Casey Lauren , O’Connell Colleen
Published: December 2022

BACKGROUND: Spinal Muscular Atrophy (SMA) is a hereditary neuromuscular disease with an estimated prevalence of 1/10 000 births. SMA is increasingly recognized as a multi-system disease with a need to study additional under-recognized health domains such as quality of life, fatigue, bulbar function, respiratory function, and independence. OBJECTIVE: Identify and assess reported evidence from the literature investigating Patient Reported Outcome Measures (PROMs) in adults with SMA. Develop a novel method drawing from network theory to graphically depict the literature, PROMs, and supporting psychometric evidence. METHODS: A scoping review was completed following PRISM-ScR, COSMIN and JBI scoping review guidelines. Literature investigating PROMs in adult SMA or neuromuscular disease was identified from peer-reviewed and grey databases. A network graph was derived from extracted data. RESULTS: 5292 articles were retrieved, 81 articles met inclusion criteria; corresponding to 31 unique PROMs. Only two PROMs were developed specifically for SMA. Few PROMs covered multiple domains of health. Most PROMs were incompletely validated, focusing on concurrent validity, and few assessed responsiveness or internal consistency. CONCLUSIONS: PROMs are emerging tools for monitoring and assessing adults with SMA. Despite their potential benefits, additional validation studies should be completed prior to their use for clinical decision-making. Network graphics may represent a technique to aid in the visualization of evidence supporting a scoping review.
Development of a pulse-width-discriminating 3He position-sensitive detector system
Authors: Sato Setsuo , Kajimoto Ryoichi , Inamura Yasuhiro
Published: December 2022

In many neutron scattering experiments, 3He-gas position-sensitive detectors (PSDs) are employed to obtain high-quality data. However, the exact position where a neutron is detected cannot be determined if two or more neutrons are simultaneously captured at different positions. This results in noise and degrades the quality of the data. In particular, such noise is a serious source of spurious scattering in inelastic neutron scattering instruments equipped with a large number of long PSDs recently developed at pulsed neutron sources. Herein, we introduce a pulse-width-discriminating PSD system that monitors the pulse width and height of the collected data. The system utilizes previously developed neutron-readout boards and removes instances of two or more simultaneous captures from the data to significantly improve the performance of PSDs. We also propose a new program to monitor the pulse width from PSD data using a hardware function implemented for other purposes. We confirm that the noise decreases to a level almost equal to that of the background. Although the developed program is applied to an inelastic scattering experiment, it is applicable to other types of experiments in which mispositioned signals should be eliminated as noise.

Double-differential cross-sections of the 9Be(p,xn) reaction are newly evaluated based on the Wakabayashi’s function and neutronics analysis up to 12 MeV for a new nuclear data library, JENDL-5. We devoted our efforts especially to the re-optimization of the absolute cross-sections and the interpolation of the neutron energy spectra. Through the comparisons between the thick target yield measurements and Monte-Carlo simulations at different proton energies and neutron emission angles, we conclude that JENDL-5 gives the best evaluation in the world.

A high flux neutron source based on a vacuum-insulated tandem accelerator (VITA) and a lithium target has been proposed and developed at the Budker Institute of Nuclear Physics in Novosibirsk, Russia. We describe VITA which provides a dc proton/deuteron beam with an energy within a range of 0.6–2.3 MeV with a current from 1 nA to 10 mA. VITA is also capable of producing α-particles through the 7Li(p,α)α and 11B(p,α) α α reactions, 478 keV photons through the 7Li(p,p ′ γ)7Li reaction and positrons through the 19F(p,e+e−)16O reaction. We present several applications of this source: boron neutron capture therapy, nuclear cross sections determination, lithium target study, radiation blistering of metals during proton implantation and the radiation testing of promising materials.

BACKGROUND: Americans with disabilities have historically faced substantial barriers to employment participation. The state-federal vocational rehabilitation (VR) program has played an important role in increasing the employment opportunities of Americans with disabilities through the provision of services and supports designed to lead to high-quality employment, independence, self-sufficiency, and full integration into the community. OBJECTIVE: The Vocational Rehabilitation Technical Assistance Center for Quality Employment (VRTAC–QE) was designed to bring together the broad range of existing quality employment strategies and supporting practices, identify and implement new ones, and incorporate them into an integrated training and technical assistance plan, consistent with the circumstances and priorities of each State VR agency that requests technical assistance. METHOD: In the present paper, we present the results of a needs assessment survey conducted among State VR rehabilitation counselors and professionals in cooperating rehabilitation agencies and services. RESULTS: The purpose of the present study was to determine technical assistance and training needs of State VR counselors in four practice domains: (a) outreach services, (b) pre-employment transition services, (c) vocational rehabilitation services, and (d) employment services. CONCLUSION: Implications and future directions are also discussed.
The efficacy of competitive integrated employment versus segregated employment for persons with disabilities: A systematic review

BACKGROUND: Although competitive integrated employment (CIE) has been established as a goal of employment policy and practice for individuals with intellectual and developmental disabilities (IDD), many still receive segregated vocational services for subminimum wage. This persistence of segregated vocational services has occurred despite substantial previous research recommendations and policy directives to encourage CIE. OBJECTIVE: The purpose of this systematic review was to examine whether recent research might provide further evidence of the role of segregated vocational services in contributing to or detracting from positive outcomes. METHOD: Our review searched peer-reviewed literature from seven electronic databases and screened 589 peer-reviewed articles based on inclusion criteria established following PRISMA guidelines— resulting in a final sample of five studies. In the second phase of our analysis, we provide a comparison of segregated and integrated vocational services in terms of individual outcomes. RESULTS: Our findings provide further evidence against the use of segregated vocational services for individuals with IDD. CONCLUSION: Implications of these findings for future research, policy, and practice are provided.

BACKGROUND: Adequate, accessible public transportation is essential to fully address social and economic disparities that exist among individuals with disabilities. Despite removal of many physical barriers within transportation systems, significant barriers to public transportation for people with disabilities are still widespread. OBJECTIVE: Transportation is commonly cited as an obstacle to employment for individuals with disabilities, and as a result, a thorough analysis of specific factors influencing the use of public transportation by individuals with disabilities is necessary to fully understand patterns of use. METHOD: The current study used a national sample of individuals with disabilities in pursuit of employment to investigate characteristics that predict the receipt of transportation services by vocational rehabilitation personnel. RESULTS: Results indicate individuals who were not employed, who were receiving welfare and/or TANF, who were homeless, who were living in rehabilitation facilities, and/or who were living in substance abuse treatment centers were more likely to receive transit services from vocational rehabilitation programs. Also, individuals with substance use problems, mental health disorders, HIV/AIDS or other immune deficiency disorders, and/or people from racial or ethnic minority backgrounds were more likely to receive transit service support from vocational rehabilitation programs. CONCLUSION: Improvement in transportation services for individuals with disabilities is needed on a systems and individual level. State rehabilitation counselors can evaluate the extent high-risk clients identified in this study can benefit from transit services as well as other wrap around services that can improve their engagement in VR services leading to better employment outcomes.

The popularity of mobile food delivery apps (MFDAs) and the online food delivery industry surged during the COVID-19 epidemic. Despite the explosive growth in the use of these apps, relatively limited research has been done to determine what affects their continuous use. This study predicts the continuous use of MFDAs and explores the variables that influence this utilization using a novel machine learning (ML) based approach. The machine learning models included four distinct constructs (i.e., features): perceived compatibility, convenience, online reviews, and delivery experience. These features were measured using a survey instrument. Eight different machine learning (ML) models, ranging from basic decision trees to neural networks, were deployed. All eight models achieved high prediction accuracy of above 93%, with the CatBoost model having the highest accuracy among them at 98%. Feature importance analysis revealed perceived compatibility to be the most important factor impacting the continuous usage of MFDAs followed by convenience, online reviews, and delivery experience respectively. The study’s findings have ramifications for MFDA marketing and design. Given the significance of perceived compatibility, MFDA marketing campaigns should have a strong emphasis on highlighting how well these apps fit with the users’ lifestyles.
Industrial adoption and transition towards sustainable renewable energy

Published: December 2022

A global revolution is called upon to transition into renewable sources of energy from fossil fuels in an accelerated manner by various countries to become net zero carbon emitter with self-committed timelines. This study identified carbon dioxide emissions and participation of renewable energy in total energy supply as two major dimensions and discusses the impact of various independent variables quantitively by multipanel regression in timeseries and countries for comparative correlation analysis. Theme based industry expert interviews adds qualitative dimension to the study. The results suggest that country’s energy need and availability of fossil fuels within, determines the RE adoption rate, while countries with high reliance on coal and crude are shifting towards RE sources. Investments in research and development in hydrogen, fuel cells and storage are yet to make an impact in this direction since they are recent in this long game of energy transition.
