Authors: Kuppusamy Ramya , Nikolovski Srete , Teekaraman Yuvaraja
Published: October 2023

In the current energy usage scenario, the demands on energy load and the tariffs on the usage of electricity are two main areas that require a lot of attention. Energy forecasting is an ideal solution that would help us to better understand future needs and formulate solutions accordingly. Some important factors to investigate are the quantity and quality of smart grids as they are significantly influenced by the transportation, storage, and load management of energy. This research work is a review of various machine learning algorithms for energy grid applications like energy consumption, production, energy management, design, vehicle-to-grid transfers, and demand response. Ranking is performed with the help of key parameters and is evaluated using the Rapid Miner tool. The proposed manuscript uses various machine learning techniques for the evaluation of power quality performance to validate an efficient algorithm ranking in a grid-connected system for energy management applications. The use of renewable energy resources in grid-connected systems is more common in modern power systems. Universally, the energy usage sector (commercial and non-commercial) is undergoing an increase in demand for energy utilization that has substantial economic and ecological consequences. To overcome these issues, an integrated, ecofriendly, and smart system that meets the high energy demands is implemented in various buildings and other grid-connected applications. Among various machine learning techniques, an evaluation of seven algorithms—Naïve Bayes, artificial neural networks, linear regression, support vector machine, Q-learning, Gaussian mixture model, and principle component analysis—was conducted to determine which algorithm is the most effective in predicting energy balance. Among these algorithms, the decision tree, linear regression, and neural networks had more accurate results than the other algorithms used. As a result of this research, a proposal for energy forecast, energy balance, and management was compiled. A comparative statement of various algorithms concludes with results which suit energy management applications with high accuracy and low error rates.

Published: October 2023

The transportation demands of people are increasing day by day depending on the population, and the number of vehicles in traffic is causing various problems. To meet the energy needs of vehicles, there is a huge burden on countries in terms of fossil fuels. In addition, the use of fossil fuels in vehicles has a serious impact on environmental pollution. Various studies have been carried out to prevent unnecessary fuel consumption and emissions. Behavior of drivers, who are important components of traffic, are carefully examined in the context of this subject. Driver distraction causes various environmental problems as well as traffic safety issues. In this study, the negative situations that arise as a result of drivers waiting at traffic lights dealing with their mobile phones are discussed. Roadside observations are made for drivers at considered intersections in Erzurum Province, Turkey. As a result of these observations, delays at selected intersections due to mobile phone use are calculated. Unnecessary fuel consumption and emissions due to delays are also analyzed. An annual fuel consumption of approximately 177.025 L and emissions of 0.294 (kg) NOX and 251.68 (kg) CO2 occur at only selected intersections. In addition, a second roadside observation is made in order to analyze driver behavior and the most preferred type of mobile phone usage is determined. It is seen that drivers mostly exhibit the “Talking” and “Touchscreen” action classes. Considering the economic conditions and environmental pollution sensitivities of countries, attempts have been made to raise awareness about fuel consumption and emissions at traffic lights.

Authors: Dong Chunfeng , He Jun , Du Longzheng , Yang Jing
Published: October 2023

Based on the data of China’s A-share listed companies from 2008 to 2021, this article explores the impact and mechanism of executives with environmental experience on corporate environmental performance (CEP) and finds that executives with environmental experience significantly improve CEP. The heterogeneous analysis shows that the improvement effect of executives with environmental experience on CEP is more significant in non-state-owned enterprises, non-heavy-polluting enterprises, and enterprises in regions with higher levels of marketization. The mechanism test shows that important channels for executives with environmental experience to improve CEP include attracting green investors, promoting green innovation, and obtaining government environmental subsidies. Further analysis shows that under the governance of executives with environmental experience, the improvement of CEP is conducive to strengthening corporate social responsibility and enhancing enterprise value. The research conclusions provide direct evidence for improving CEP and achieving sustainable development for enterprises and society.

Published: October 2023

Generation Z (Gen Z) accounts for 40% of the world’s consumer population. Its representatives set the market trends that will shape products and services in the near future. Taking into account the potential and characteristics of Gen Z, it seems reasonable to ask questions such as the following: To what extent are young people engaged in pro-environmental actions? Is awareness of the state of environmental degradation and consumer pragmatism related to nationality? The main purpose of this article is to assess the attitudes and pro-environmental behavioral patterns of young consumers in Poland and Germany. We conducted a review of studies available in the literature related to trends in the behavior of consumers from Gen Z and the greening of consumption. Moreover, we carried out empirical research using CAWI (Computer-Assisted Web Interviewing) methodology, with the participation of representatives of Gen Z. This study showed differences between Gen Z representatives from Poland and those from Germany in terms of their attitudes and declarations towards pro-environmental market behavioral patterns. This research has revealed a higher sensitivity towards the degradation of the environment among young consumers from Germany and has shown a lower level of environmental awareness among the representatives of Gen Z from Poland.

Published: October 2023

As populations and economies have grown rapidly, questions of land development and use have intensified. It has become a major global concern to achieve sustainable land use practices. This study reveals evolution of the spatiotemporal pattern of land development intensity of counties in Shandong Province by introducing a land development intensity measurement model combined with three-dimensional trend surface and spatial autocorrelation analyses. Geodetector and geographically weighted regression models were employed to demonstrate the interplay and spatiotemporal heterogeneity between development intensity and drivers. The empirical results show that the value of land development intensity of counties in Shandong Province shows a general growth trend, with the number of counties with higher values gradually increasing and the number of counties with lower values gradually decreasing. We also found that the spatial heterogeneity of land development intensity across counties in Shandong Province is significant, and the spatial distribution pattern is basically consistent with the “one group, two centers and three circles” strategy proposed by the Shandong Provincial Government. There is also a positive spatial correlation and clustering effect of land development intensity of counties in Shandong Province. High (low) value clusters are concentrated in core hot (cold) counties, driving some of the surrounding counties towards radial development. The alteration in the intensity of county land development is a complex occurrence that is shaped by numerous factors. Among these, GDP per capita and population density have the primary influence on land development of counties in Shandong Province. To achieve coordinated regional social, economic, and environmental benefits, land development within the county should adhere to the principle of adapting to local conditions and implement differentiated development strategies according to different development intensities.

Published: October 2023

Silk fibroin (SF) holds promise for the preparation of matrices for tissue engineering and regenerative medicine or for the development of drug delivery systems. Regenerated fibroin from Bombyx mori cocoons is water-soluble and can be processed into scaffolds of various forms, such as fibrous matrices, using the electrospinning method. In the current study, we studied the correlation between concentrations of fibroin aqueous solutions and their properties, in order to obtain electrospun mats for tissue engineering. Two methods were used to prevent solubility in fibroin-based matrices: The conversion of fibroin to the β-conformation via treatment with an ethanol solution and chemical cross-linking with genipin (Gp). The interaction of Gp with SF led to the appearance of a characteristic blue color but did not lead to the gelation of solutions. To speed up the cross-linking reaction with Gp, we propose using chitosan-containing systems and modifying fibrous materials via treatment with a solution of Gp in 80% ethanol. It was shown that the composition of fibroin with chitosan contributes to an improved water resistance, reduces defective material, and leads to a decrease in the diameter of the fibers. The electrospun fiber matrices based on regenerated fibroin modified by cross-linking with genipin in water–alcohol solutions were shown to promote cell adhesion, spreading, and growth and, therefore, could hold promise for tissue engineering.

Published: October 2023

Urdbean leaf crinkle disease (ULCD) affects mainly the urdbean or blackgram (Vigna mungo (L.) Hepper) causing distinct symptoms that often result in serious yield losses. It has been known to occur for more than five decades and is considered to be of viral etiology. The identity of the causal agent, often referred to as the urdbean leaf crinkle virus, is not unequivocally proved. There are few attempts to characterize the causal agent of ULCD; however, there is no unanimity in the results. Recent attempts to characterize the causal agent of ULCD using next-generation sequencing of the virome of ULCD-affected urdbean plants indicated the involvement of cowpea mild mottle virus; however, without conforming through Koch’s postulates, the etiology of ULCD remains inconclusive. Claims of different insect vectors involved in the transmission of ULCD make this disease even more mysterious. The information available so far indicates that either two different viruses are causing ULCD or a mixture of viruses is involved. The identity of the virus/es causing ULCD still remains to be unambiguously ascertained. In this review, we attempt to analyze information on the various aspects of ULCD.

Immune dysregulation and cancer treatment may affect SARS-CoV-2 vaccination protection. Antibody production by B-cells play a vital role in the control and clearance of the SARS-CoV-2 virus. This study prospectively explores B-cell seroconversion following SARS-CoV-2 immunization in healthy individuals and non-small cell lung cancer (NSCLC) patients undergoing oncological treatment. 92 NSCLC patients and 27 healthy individuals’ blood samples were collected after receiving any COVID-19 vaccine. Serum and mononuclear cells were isolated, and a serum surrogate virus neutralization test kit evaluated SARS-CoV-2 antibodies. B-cell subpopulations on mononuclear cells were characterized by flow cytometry. Patients were compared based on vaccination specifications and target mutation oncological treatment. A higher percentage of healthy individuals developed more SARS-CoV-2 neutralizing antibodies than NSCLC patients (63% vs. 54.3%; p = 0.03). NSCLC patients receiving chemotherapy (CTX) or tyrosine kinase inhibitors (TKIs) developed antibodies in 45.2% and 53.7%, of cases, respectively, showing an impaired antibody generation. CTX patients exhibited trends towards lower median antibody production than TKIs (1.0, IQR 83 vs. 38.23, IQR 89.22; p = 0.069). Patients receiving immunotherapy did not generate antibodies. A sub-analysis revealed that those with ALK mutations exhibited non-significant trends towards higher antibody titers (63.02, IQR 76.58 vs. 21.78, IQR 93.5; p = 0.1742) and B-cells quantification (10.80, IQR 7.52 vs. 7.22, IQR 3.32; p = 0.1382) against the SARS-CoV-2 spike protein than EGFR patients; nonetheless, these differences were not statistically significant. This study shows that antibodies against SARS-CoV-2 may be impaired in patients with NSCLC secondary to EGFR-targeted TKIs compared to ALK-directed treatment.
Effects of a Single Session of Whole Body Vibration Compared to Multiple Sessions—An Updated Review and Meta-Analysis
Authors: Dincher Andrea
Published: October 2023

Parkinson’s disease is an incurable neurological disease. Only the symptoms can be treated with medication or exercise therapy. The present analysis is intended to show how whole-body vibration training affects the symptoms of Parkinson’s disease, distinguishing between acute and long-term effects. Methods: online databases (EMBASE, PubMed, PEDro) were searched for reviews, meta-analyses and new studies since the previous most recent review/meta-analysis. Studies with at least a medium methodological quality (PEDro score at least 5 points) were selected. Results were presented as forest plots that indicated standardized mean differences with 95% confidence interval. Results: Sixteen studies were found with a PEDro-score of at least 5 points. Of these, three studies were excluded from the qualitative analysis because the necessary data, such as standard deviation or control group results, were missing. The effect sizes are very mixed. In some parameters there is no effect, in others a very strong effect. The effects in the comparison between single and multiple treatments are similar. Discussion: The different effects may be partly due to the different vibration frequencies or sentence durations, as well as to different valid test procedures. Conclusions: Since the study situation still does not show clear results, further studies must follow that compare different frequencies, sentence durations and vibration types with each other, so that training recommendations can be given on this basis.
Influencing Factors and Nutrient Release from Sediments in the Water Level Fluctuation Zone of Biliuhe Reservoir, a Drinking Water Reservoir
Authors: Li Weijia , Xu Shiguo , Chen Xiaoqiang , Han Dongning , Mu Baoquan
Published: October 2023

Significant amounts of nitrogen and phosphorus in sediments will be released into the overlying water during the flood season in the water level fluctuation zone (WLFZ) of reservoirs that undergo periodic drying and flooding. This will result in water quality deterioration of the reservoir. In order to clarify the distribution characteristics and release behavior of nitrogen (N) and phosphorus (P) from sediments in the WLFZ of a reservoir, this study analyzed the sediment distribution characteristics and potential exchange flux sediment–water interface(SWI) through field investigations and sediment core incubation experiments. And the main factors affecting the release of N and P through the incubation experiments in sediments of the WLFZ in the reservoir were determined. Our findings indicated that the sediment in the WLFZ serves as the primary source of NH4+-N and acts as a sink for NO2-N in the overlying water of sediment. The concentration of NH4+-N in the interstitial water of sediments is the key factor that affects the water quality of Biliuhe Reservoir. Total nitrogen content of surface sediments in the WLFZ of Biliuhe Reservoir ranges from 1052.52 ± 49.39 to 3520.54 ± 30.31 mg/kg. High concentrations of N pollution are the primary increased risk of eutrophication in Biliuhe Reservoir during summer. The sediment N and P release flux of BLH1 located in the main stream is 1.67 ± 1.06 and 12.32 ± 2.42 mg·(m2·d)−1, respectively, which is smaller than that of BLH2 (3.27 ± 2.15 and 15.19 ± 2.36 mg·(m2·d)−1, respectively), BLH3 (4.24 ± 1.74 and 17.02 ± 2.47 mg·(m2·d)−1, respectively) and BLH4 (7.78 ± 2.03 and 20.56 ± 2.38 mg·(m2·d)−1, respectively) located in the tributary. It indicates that the water conveyance project located in BLH1 has an impact on nutrient scouring of sediments in the WLFZ at this site. The main water environment factor affecting the release of N and P in the sediment of the WLFZ is dissolved oxygen (DO). And the Pearson correlation coefficients between TN and TP with DO were −0.838 and −0.777, respectively (p < 0.05). At the same time, the diffusion of nutrients in the sediments can be effectively inhibited by maintaining a certain DO concentration in the overlying water.

Published: October 2023

Relevance.Prognosis of the dentofacial system (DS) development in children with dentofacial deformities (DD) is an urgent medical and social problem since the prognosis of the DS development will allow timely prescription and provision of adequate therapy, which will significantly reduce the risks of severe DD development in children. Machine learning methods have proven to be a reliable tool for predicting a patient's health status and evaluating the effectiveness of treatment methods. Therefore, it seems interesting to use this modern toolkit to build predictive models that allow us to assess the change in the condition of DS in children with DD after orthodontic treatment (OT) at different ages or without OT.

Purpose.The study aimed to build a set of predictive models for assessing the severity of the dentofacial system condition in 3.5-4-year-old children after and without orthodontic treatment.

Material and methods.The study used the data on the DS of children aged 3-5 years (n=50), 6-9 years (n=100), 10-12 years (n=100) and 13-17 years (n =100). The author's program was developed in Python 3.11 using the sklearn, pandas, and xgb libraries in Anaconda to build the predictive models.

Results.We developed nine models of the DS condition in children aged 3-12 years, three of which make predictions for the DS development after the OT (one - in the group of 3 – 5-year-old children, the second – in the group of 6 – 9-year-old children and the third – in the group of 10 – 12-year-olds) and six models predict the development of the DS without OT. Three out of 6 models predict DS development without OT at 3-5 years: the first makes a prediction of the DS condition for 6-9 year-olds; the second – for 10-12 year-olds; the third – for 13-17-year-olds. The accuracy of the models ranges from 82 to 86%. Two models out of 6 predict the DS development for children with DD who did not receive OT at 6-9 years old: one – at 10-12 years old, the second – at 13-17 years old. The accuracy of the models ranges from 92 to 97%. The sixth model makes predictions of the DS condition in children aged 13-17 years who did not receive OT at the age of 10-12 years. The accuracy of the model is 94%. In addition, we built three models that predict the DS condition in 3.5-4 years after the OT: the first model predicts for 3–5-year-old children; the second – for 6–9-year-olds; and the third - for children of 10–12 years old. The accuracy of the models ranges from 82 to 90%.

Conclusion.All obtained models will be used to build a web application for predicting the DS state severity in children after the orthodontic treatment and without the latter.

Electrocatalysts for Formic Acid-Powered PEM Fuel Cells: Challenges and Prospects
Authors: Cheng Hongfei , Wang John , Wu Chuan , Liu Zhaolin
Published: October 2023

In view of the drawbacks of rechargeable batteries, such as low mass and volumetric energy densities, as well as slow charging rate, proton exchange membrane fuel cells (PEMFCs) are reckoned to be promising alternative devices for energy conversion. Currently, commercial PEMFCs mainly use H
2
as the fuel, but the challenges in generation, storage, and handling of H
2
limit their further development. Among the liquid fuels, formic acid possesses the merits of low flammability, low toxicity, slow crossover rate, faster reaction kinetics, and high volumetric H
2
storage capacity, thus being considered as the most promising energy carrier. It can be used as the energy source for direct formic acid fuel cells (DFAFCs) and formic acid-based H
2
-PEMFCs, which are also called indirect formic acid fuel cells (IFAFCs). A common issue hindering their commercialization is lacking efficient electrocatalysts. In DFAFCs, the anodic electrocatalysts for formic acid oxidation are suffering from stability issue, whereas the cathodic electrocatalysts for oxygen reduction are prone to poisoning by the permeated formic acid. As for IFAFCs, CO and CO
2
impurities generated from formic acid dehydrogenation will cause rapid decay in the catalytic activity. High working temperature can improve the CO and CO
2
tolerance of catalysts but will accelerate catalyst degradation. This review will discuss the mitigation strategies and recent advances from the aspect of electrocatalysts to overcome the above challenges. Finally, some perspectives and future research directions to develop more efficient electrocatalysts will be provided for this promising field.
Nondestructive Nonlinear Optical Microscopy Revealed the Blackening Mechanism of Ancient Chinese Jades
Authors: Chen Yaxin , Wang Rong , Ji Minbiao
Published: October 2023

Jade is most valued in Chinese culture since ancient times. For unearthed jade artifacts, the alteration color resulting from weathering effects and human activities provides information for cultural heritage conservation, archaeology, and history. Currently, the noninvasive 3-dimensional characterization of jade artifacts with high chemical and spatial resolution remains challenging. In this work, we applied femtosecond pump–probe microscopy and second harmonic generation microscopy techniques to study the black alteration of an ancient jade artifact of the late Spring and Autumn period (546 to 476 BC). The direct cause of the “mercury alteration” phenomena was discovered to be the conversion of metacinnabar from buried cinnabar in the tomb. Furthermore, a 3-dimensional optical reconstruction of the black alteration was achieved, providing a high-resolution method for analyzing the blackening mechanism without the need of sample damage. Our approach opens up new opportunities to extract microscopic spatiochemical information for a broad range of alteration colors in jade artifacts.

The study aims to examine the environmental threats to social and economic human well-being in today’s unclear circumstances, as well as find a leveling tool for the business ‒ state ‒ society system. At the present stage, the most significant environmental threats in various regions of the world are identified as follows: increased carbon and methane emissions, air pollution, and lack of public water access. A comparative analysis of effects on the environment and the achievement of environmental goals in sustainable development in various countries is carried out. Russia’s place in the ranking of spreading environmental threats is determined. Financial and implementation trends for measures aimed at protecting environmental wellness and eliminating environmental threats in Russia are analyzed. The study reveals an increase in the state’s budget spent on environmental pro-tection from 2010 to 2021, as well as in the commissioning of water and air pollution protection facilities, including sewage treatment. A decrease in the circulation water supply system and trapping and processing facilities for end gases’ harmful substances is detected. The authors have determined that Russia is far behind developed countries in the European Union in terms of environmental inno-vations implemented by organizations. Based on the positive practice of foreign states, directions for supporting social and economic human well-being are substantiated through the implementation of measures aimed at preventing environmental threats’ onset and spread.

Aim. To compare the long-term outcomes of the catheter ablation (CA) using remote magnetic-guided navigation (RMN) and manual radiofrequency CA (MAN) in patients with congenital heart defect (CHD) and incisional atrial tach-yarrhythmias (AT).

Methods. In this retrospective study cohort, 67 patients were included with CHD and AT. CHD were classified based on complexity (simple, moderate, and complex) according to ACC/AHA guidelines 2008. Fifty-seven (85%) patients underwent at least one surgical procedure for CHD correction before CA. The patients were divided into the     two groups regarding CA approach: the MAN group (n=42) and the RMN group (n=25). The primary endpoitnts was long-term freedom from any AT, including atrial fibrillation. Key secondary endpoints included perioperative and late complications. To compare freedom from any AT between the groups, 1:3 propensity score matching was applied, and 63 patients were matched. The matching was exact on CHD complexity. The weighted matched observations were assessed with univariate Cox regression with any AT as the outcome.

Results. The median follow-up period was 20 months. In the matched MAN and RMN groups, 92.3% and 83.3% patients, respectively, had incisional АТ (p=0.27), the other patients having additionally AF. The mean fluoroscopy time was statistically significant lower in the RMN group compared with MAN (р=0.009) with longer procedural duration   in the RMN group (p<0.001). There was no statistically significant difference in perioperative and late complications. The freedom from any AT 36 months after CA was 78.9% in the matched RMN group and 47.2% in the matched MAN group. The comparison of freedom from any AT between the groups yielded p=0.040, hazard ration 0.32 [95% confidence interval 0.11; 0.95].

Conclusion. RMN CA was superior over manual CA with respect to long-term freedom from AT in patients with CHD with similar safety profile.

The four caliphs in Islamic history are called al-rasyidin hulefaur. Based on this, the author tries to discuss the leadership of the Rashidun Khulafaur. (2) to find out who the Rashidun Khulafah were, and (3) to find out the development of Islam as a political force. The research method used in this research is historical research method. The results of this study are first, the history of Islamic civilization during the al-Kulafa era, then who the Rashidun Caliphate was and the development of Islam in political power.
Adolescents and violent extremism in the online space
Authors: Kozlova I. V.
Published: October 2023

The article argues that belonging to destructive subcultures is an important risk factor for adolescents’ problem behavior. The relevance of the study is due to the fact that participation in online space represents a significant aspect of teenagers’ involvement in extremist and terrorist movements. The author has attempted a systematic review of the role of the Internet and social networks in the violent radicalization of adolescents, outlined ways to prevent extremism in adolescents and intervene in violent radicalization. The purpose of the study is to assess the relationship between extremist adolescent subcultures and the use of the Internet, and to examine the role of various factors in introducing adolescents to destructive subcultures on the Internet. As research methods, quantitative and qualitative types of analysis of adolescent behavior were used to identify the reasons for their involvement in destructive subcultures on the Internet, and a systematic review of scientific publications related to risk factors contributing to deviant behavior among adolescents was performed. The author concludes that the importance of ideology for adolescents follows, rather than precedes, entry into extremist subcultures. Joining a group is part of grouping, which is especially significant during adolescence. Preventive actions that start within the family are one solution to keep adolescents away from criminal acts. State programs of social orientation of adolescents and their positive empowerment are also necessary.

Eles são abundantes e aplicados em várias áreas, pois proporcionam estruturas em nanoescala com diversas propriedades como biodegradabilidade, atoxicidade, biocompatibilidade e maior reatividade. Este estudo prospectivo mapeou documentos de patentes sobre nanobiopolímeros, com o objetivo de obter informações sobre as tendências do setor, por meio da base de dados European Patent Office, pela combinação de palavras-chave. Os Estados Unidos são o principal país depositante de patentes e têm também os principais inventores, institutos e empresas depositantes. Países asiáticos e emergentes, como o Brasil, também figuram entre os países de destaque. Os polissacarídeos são as principais matrizes utilizadas para a obtenção e/ou aplicação dos nanobiopolímeros, e a celulose e o amido são os mais empregados. Observou-se uma boa diversidade de compostos nanobiopoliméricos. De maneira muito explícita, o setor da saúde é o que mais se destaca nas aplicações das nanoestruturas biopoliméricas (em que figuram as áreas médica e farmacêutica). Outros setores como embalagens, aplicação de aglutinantes, encapsulação e tratamento de água também figuraram entre as aplicações.

There are many pediatric patients who visit the Cibogo Health Center to get dental health services, but when dental services are about to be carried out, many children feel anxious and afraid when they will have their teeth examined, therefore it is important to divert attention to children to reduce excessive anxiety during dental and oral health services. The purpose of this study was to analyze the anxiety level of pediatric patients before and after showing cartoon films on the anxiety level of pediatric patients. The research method used was a pre-experimental design method with a one group pretest and posttest research design. At the beginning of the one group pretest posttest design, observations were made through the pretest first, then given treatment or intervention, then given a posttest so that you can find out the changes that occurred before and after being given treatment or intervention. The sample used in this research is Accidental Sampling.The results of the study showed that there was an effect of the distraction technique of showing cartoon films on the level of anxiety in pediatric patients. The conclusion of this study is the anxiety level of pediatric patients at the time before being given a distraction with the criteria of anxiety 36.7%, Very Anxious 23.3%; The anxiety level of pediatric patients after being given a distraction with the criteria of anxiety was 13.3%, Very anxious was not there (0%) and wilcoxon test results with a significance value of 0.014. The conclusion is that there is an influence of the distraction technique of showing cartoon films on the anxiety level of pediatric patients.
ЧИСЛОВІ ДОСЛІДЖЕННЯ ДВОСТАДІЙНОГО ПРОЦЕСУ ТЕРМОХІМІЧНОЇ ПЕРЕРОБКИ БІОМАСИ В УСТАНОВЦІ З ФІКСОВАНИМ ШАРОМ ПРОДУКТИВНІСТЮ 1250 КГ/Ч

Published: October 2023

З використанням побудованих моделей, що описують процеси піролізу біомаси (Bagasse) та газифікації її коксозольного залишку, отримано детальну інформацію про конструктивні характеристики реактора, вихід і склад піролізних газів, аеродинаміку, тепломасообмін і хімічне реагування газодисперсного середовища. Ці результати були використані під час розробки двох оригінальних конструкцій установок термохімічної переробки біомаси продуктивністю за Bagasse 1250 кг/год і 232,3 кг/год (на суху масу). В установці з великою продуктивністю, 1250 кг/год, на один піролізер припадає два газифікатори для конверсії коксозольних частинок Bagasse: внутрішній газифікатор продуктивністю 68 кг/год та зовнішній – 271 кг/год. У разі малої продуктивності, 232,3 кг/год, на один піролізер встановлюється лише зовнішній газифікатор.

На відміну від існуючих установок термохімічної переробки біомаси, тут з реактора виходять два різні за складом та теплотворною здатністю синтетичні гази: низькокалорійний генераторний газ (об'ємні частки) − CO2 = 3,38 %, CO = 32,56 %, H2 = 17,2 %, H2О = 4,29 % та N2 = 42,570 % з теплотворною здатністю 5971 кДж/нм3 і середньокалорійний піролізний газ − CO2 = 11,2 %, CO = 38,56 %, H2 = 26,9 %, C1.16H4 = 22,76 % (70 % CH4+30 % C2H4), C6H6.2O0.2 = 0,31 % та N2 = 0,32 % з калорійністю 17904 кДж/нм3.
Challenges and Prospects of University Advancement Centres in Nigerian Universities
Authors: Agbarakwe Ugochukwu Henry
Published: October 2023

Nigerian Universities are grossly underfunded. But the underfunding is a worldwide phenomenon. In the face of this underfunding the US universities have maintained their top ranking in the world and South Africa have maintained their’s in Africa. One major secret of these universities’ performance is their ability to raise funds from alternative sources through the University Advancement centers. Nigerian universities, beginning with University of Port Harcourt, Bayero University Kano, University of Ibadan, Ahmadu Bello University and University of Jos, through the promptings and assistance of the MacArthur and Carnegie foundations, have established the Advancement centres. But unlike the experience of the US and South African universities, the Nigerian universities have reaped very sub-optimal benefits from these centres. This paper presents and discusses the challenges faced by these centres and what can be done to reposition the centres to start tapping from the large pool of funds existing both within the country and internationally for the development of their universities. This will improve their infrastructure and lead to the production of quality human capacity and research outputs needed by the economy for economic advancement.
The Inhibition Characteristics of Moringa oleifera Leaf Extract on Mild Steel in Tetraoxosulphate (VI) Acid and Sodium Hydroxide Environments

The inhibiting effects of Moringa oleifera leaves extract on the corrosion of mild steel in 0.5 M and 1.0 M both of H2SO4, and NaOH solution have been investigated using weight loss techniques. A total of 72 mild steel coupons of dimensions 10 mm x 5 mm x 5 mm were suspended using nylon strings in beakers containing the media with the leaf extract, obtained by Reflux method in concentrations of 5 ml, 10 ml, 15 ml and 20 ml respectively. The setup was allowed to stand for 28 days with a coupon withdrawn from each beaker at 7 days interval for corrosion analysis. The corrosion rate profiles showed behaviors similar to those of passivating metals that begins with a steep rise in corrosion rate and progressively decreases with increasing exposure time. However, it was noticed that at an exposure time of 14 days, the coupon in the 5 ml concentration experienced a sporadic rise in corrosion rate, which we attribute to the collapse of the passive film as a result of system agitation. The inhibition efficiency of the leaf in both media was significant, suggesting that it can be used as a green and eco-friendly alternative to the synthetic and rather hazardous inhibitors in use today. In conclusion, when compared, it was established that the inhibition potentials of the leaves were better in H2SO4 than in NaOH.
