In the article the results of study of the structure and micro-hardness of the surface layer of 38Cr2MoAl steel after volumetric quenching and high tempering, followed by ion-plasma nitriding, in comparison with electromechanical surface hardening (EMSH) are presented. Experimentally confirmed, that after the EMSH of 38Cr2MoAl steel, a gradient microstructure of finely dispersed martensite, bainite and austenite with a residual hardness of up to 8100 HV MPa and a depth of up to 0.8 mm is formed in the surface layer. At the same time, the maximum microhardness of the surface layer is not on the surface, but at a depth of 0.1 mm. The EMSH is formed by gradient surface layers of metal of high hardness on the surface of products. For a wide range of machine parts, EMSH can be used as a finishing treatment, since it is not accompanied by the presence of defects in the decarburization of the surface layer and deterioration of roughness. After ion-plasma nitriding for 8 hours, the microhardness of the surface layer of 38X2MYA steel was 9030 HV MPa at a depth of 0.1 mm and 8650 HV MPa at a depth of 0.2 mm. At a depth of 0.3 mm, the microhardness of the surface after nitriding and EMP are almost equal, respectively 7230 and 7170 HV MPa. The results of wear tests according to the “rubber roller — fixed sample” scheme and the American Society for Testing and Materials (ASTM G65) “Standard Method for Measuring Abrasive Abrasion using the “Dry Sand” Installation/Rubber wheel” showed high wear resistance of nitrided samples. However, with the continuation of the tests, due to the shallow depth of the nitrided layer (up to 0.3 mm), the wear resistance of the nitrided and hardened samples is leveled. The practical significance of the study is associated with the possibility of reducing the cost of manufacturing parts from nitrided steels by hardening the executive surfaces of the products of the EMSH. In addition, the EMSH allows steel 38Cr2MoAl for surface hardening and subsequent finishing by finishing turning on metal-cutting machines.

Research on optimization method of flotation kinetic model based on molybdenite particle size effect
Authors: Wan He , An Yanni , Qu Juanping , Zhang chonghui , Xue Jiwei , Wang Sen , Bu Xian zhong
Published: April 2023

Flotation kinetic models can be applied to describe the flotation process and to predict mineral recoveries. However, the size composition of the target minerals in the feed ore fluctuates considerably, resulting in insufficient accuracy with flotation kinetic models. There have been many studies that focus on the investigation of flotation kinetics with different particle sizes, while the optimization methods for flotation kinetic models based on particle size effects have not been reported. In this paper, flotation tests, optical microscope observations, and particle size analysis were used to identify the reasons for the decrease in accuracy of the flotation kinetic model due to changes in the composition of molybdenite particle size. Additionally, an optimization method for the flotation kinetic model was developed based on the particle size effect. The test results show that the accuracy of the flotation kinetic model for fixed particle size minerals is very high, but the predicted results for flotation recoveries of different particle size mineral mixtures have large deviations. The poor accuracy might be due to the autogenous carrier effect caused by the particle size composition fluctuating considerably. The optimization method for the flotation kinetic model is based on the particle size effect. The model can accurately describe the flotation process of molybdenite with different size compositions of molybdenite and predict the flotation recovery of molybdenite.

Published: April 2023

The use of digital technology has become a useful and also a preferred process in the realization of dental prosthetic restorations, because through it, superior quality dental prostheses are obtained in terms of aesthetics, accuracy of execution and durability. CAD/CAM technology is changing all aspects of dentistry, making dental restoration processes much easier and more efficient for dentists, patients and dental technicians. The materials that can be used to manufacture dental restorations designed using Exocad software depend on the type of restoration (crowns, bridges, veneers, etc.) and the manufacturing method (milling with a 3-, 4-, or 5-axis CAM device); available materials include: PMMA (polymethyl methacrylate) and zirconia. Using digital technology, in this study we performed 6 fixed prosthetic restorations, of which 5 unidental restorations (5 dental crowns) and 1 pluridental restoration (a 4-element dental bridge); of the 6 prosthetic restorations, 3 restorations will be fixed by cementing on dental abutments, and 3 restorations will be fixed by screwing on implants. Digital technology allows the use of higher quality materials, resulting in more resistant and more aesthetic prosthetic restorations; helps reduce the occurrence of errors; obtaining a better marginal adaptation and a perfect adaptation to the anatomical structures of the patient s teeth.

Authors: Horsth Dienifer F L , Primo Julia de O , Balaba Nayara , Anaissi Fauze J , Bittencourt Carla
Published: April 2023

Green chromium and red iron oxides are technically important pigments due to their high color intensity, good dispersibility in paints, and superior hiding power. We report on the synthesis of colored pigments of mixed oxides with a corundum-type structure. The pigments are obtained via the addition of coloring ions to boehmite from recycled metallic aluminium. X-ray diffractometry (XRD) and Raman spectroscopy confirmed the crystallographic phase. Additionally, the oxidation state 3+ responsible for the greenish (chromium) and reddish (iron) coloration of the mixed oxides was confirmed by XPS and visible-light absorption measurements. The colorimetric stability of the oxides in acid and alkaline environments was evaluated. After 240 h of exposure to harsh environments, both pigments demonstrated stability and showed no strong color difference.

Authors: Pehlivan Başak , Duran Erdoğan , Pehlivan Veli Fahri , Koyuncu İsmail
Published: April 2023

Aim: Dexmedetomidine; it is widely used in anesthesia and intensive care. We aimed to examine and compare the cytotoxic, reactive oxygen species (ROS) and apoptotic effects of dexmedetomidine on kidney cells (Hek-293) in vitro at two different high and cumulative doses.
Material and Methods: The half-maximum inhibitory concentration (IC50) dose of dexmedetomidine on Hek-293 cells was determined using the 3-[4,5-dimethylthiazol-2yl]-2,5-diphenyltetrazolium bromide (MTT) method. Then at two different doses of the drug; apoptotic effects were determined by Annexin-V Method, morphological examinations were determined by Acridine Orange Ethidium Bromide Method and intracellular ROS levels were determined by flow cytometry.
Results: The IC50 value of dexmedetomidine for Hek-293 cells was determined as 64.6559 μg/mL. Compared with the control group, doses of 50 and 100 µg/mL of dexmedetomidine tended to show cytotoxicity (p<0.05). dexmedetomidine was found to have a lower cytotoxic effect at a dose of 50 μg / mL than at a dose of 100 μg / mL (p<0.05).
Conclusion: In the study, it was determined that dexmedetomidine increased intracellular ROS more than clinical doses at two different concentrations on Hek-293 cells, cytotoxic doses caused an increase in ROS in cells and induced apoptosis. We think that the toxic effects of dexmedetomidine can be prevented with the data obtained from this study and further studies.

Published: April 2023

Knowledge exchange and transfer are very important in a R&D environment driven by knowledge and technology. This paper aims to study the structural evolution features of the Collaborative Innovation Network (CIN) of college students from the perspective of knowledge flow. The knowledge flow among the collaborative innovation relationships of college students has not only produced many innovation achievements and high innovation conversion values, but also promoted knowledge sharing and increased regional economic benefit. To figure out the structural evolution features of CIN from the perspective of knowledge flow, at first, this paper explores the network-shaped knowledge flow pattern, constructs a model that can reflect the innovators’ citation of innovation knowledge and the interaction between related factors and their interaction space, and analyzes the distance attenuation of knowledge flow of CIN and its evolution trend. Then, this paper combines the structure of CIN with the evolutionary game, builds an Evolutionary Game (EG) model of CIN, and analyzes the evolution law of college students’ collaborative innovation behavior in CIN. At last, this paper gives experimental results and verifies the validity of the proposed model.

Published: April 2023

The Internet of Things (IoT) is an interconnected network of electronic objects, machines, and physical items in our environment. Wireless Sensor Network is the key component of Internet of Things. Wi-Fi is used by IoT to link home appliances to the internet so that they may be managed and controlled remotely. Sensors were used in WSN technology to sense and gather data from various smart home components, then send it to a gateway. In this paper, the performance of IoT based WSN had been examined when the Jammers interfered with the normal operation of the network and caused deficiency in network from the delay, throughput and data dropped points of view which they are important parameters to examine the performance of any network. The aim of this paper is to improve the degradation in performance caused by Jammers using three Ad Hoc routing protocols (AODV, OLSR and GRP) in number of different Riverbed Modeler Simulation scenarios for different audio and video applications. The results showed that the Ad Hoc routing protocols played a significant role in network performance. AODV had been investigated a better delay and data dropped improvement with acceptable throughput improvement while OLSR had the best throughput among other routing protocols with acceptable improvement in delay and data dropped. According to the research, an intelligent system should be used to decide whether a route is used for applications with a high throughput requirement or low delay and data loss.

Authors: Liu Xia , Cao Jia-Nan , Liu Tao , Zhong Huan , Liu Mi , Chang Xiao-Rong , Liu Qiong
Published: April 2023

Objective:

The objective of this study was to observe the effect of herb-partitioned moxibustion (HPM) on the gut microbiota of rats with diarrhea-predominant irritable bowel syndrome (IBS-D).

Materials and Methods:

A total of 48 male rats were randomly divided into a normal control group and an irritable bowel syndrome (IBS) model group. Using acetic acid irrigation and constraint stress, an IBS-D rat model was developed. After the model was made, the IBS rats were divided into IBS, HPM group, and pinaverium bromide (PB) group. The HPM received HPM for 20 min every day, while the PB was given gastric perfusion once a day for 14 days. After modeling and treatment, the abdominal withdrawal reflex, fecal character score, and fecal water content of rats were scored, and a 16S rRNA sequencing analysis was performed on the gut microbiota.

Results:

After treatment, the fecal character score and fecal water content in the HPM increased significantly, while visceral sensitivity decreased. Investigation of 16S rDNA sequencing revealed that α-diversity was reduced in the IBS, and HPM could increase the diversity of flora. The flora structure of IBS-D rats changed. HPM can increase the abundance of probiotics such as Akkermansia and reduce the abundance of opportunistic pathogens such as Bacteroides and Prevotella. Functional prediction analysis showed that the HPM was mainly related to the bacillary secret system, tricarboxylic acid cycle, and other pathways.

Conclusion:

HPM can regulate the gut microbiota of rats with IBS-D.

Published: April 2023

Over-exploitation coupled with adverse effect of increased human activities and lack of standard plantation endangers the germination of Lannea microcarpa seeds. An experiment was carried out to check the effect of different pre-sowing treatments on seed germination of African Grape (Lannea microcarpa L.). Pot trials was conducted during dry season at Botanic garden, Department of Plant Science and Biotechnology, Faculty of Life Science, Federal University Dutsin-Ma, Katsina State using completely randomized design (CRD). Seeds were subjected to three different concentrations of sulphuric acid, hot water, cold water, physical treatment and untreated seed as control and were analyzed independently to obtain the best treatment periods. To remove the fungal spore and exudate, a total of nine hundred and sixty (960) viable seeds were selected and surface sterilized in 1.0% Sodium-hypochlorite (NaOCl) for 1 minute and rinsed three (3) times in sterile distilled water. 20 viable seeds were sown for each polypot. In chemical pre-sowing treatments, maximum germination percentage (85.00%) and early days to seedling emergence (8.00 days) were significant (P≤ 0.05) in seed treated with 50% dilute H2SO4 for 1 hour when compared to control and other time intervals. Similarly, in physical pre-sowing treatment, days to early emergence of the seedling were recorded in seed with full-sided scarification (6.00 days). Highest germination percentage (90.00 %) and early days to seedling emergence (6.00 days) were recorded in seed immersed in hot water for 10 minutes when compared to untreated (15.00 days). In Seeds immersed in cold water, the result did not produce significance differences (P> 0.05) among the treatments except for seeds immersed in cold water for 8.00 hours (80.00%) and early days to seedling emergence (6.00 days) when compared to other treatments and the untreated seed (15.00 days). These results suggested that seed with full-sided scarification (6.00 days), seed immersed in hot water for 10 minutes (6.00 days) and cold water for 8.00 hours (6.00 days) used in this study were optimum for the best treatments inducing emergence breakage of seed coat and the technology could be applied to generate seedling for future breeding programme.

The Internet of Things (IoT) refers to the billions of physical devices that are now connected to the internet, collecting and sharing data all over the world. IoT has permeated almost every aspect of human life in recent times, encompassing cities, houses, tertiary institutions, production plants, businesses, agriculture, hospitals, and medical centers. Africa is currently experiencing a delayed adoption of technology particularly IoT technology in the educational sector. Nigeria has immense IoT potential. If it is properly implemented, will likely result in enhanced productivity across all economic sectors, and a higher standard of living for the people. The impact of IoT in Nigeria, however, is not obvious this could likely be due to poor knowledge, poverty, insufficiency and lack of electricity especially in rural areas, religion, corruption, government policy, and the like. User acceptability is essential for the successful adoption of any information technology (IT) or information system. This study investigated the behavioral intentions of students and staff at tertiary institutions in Kaduna metropolis to adopt IoT technology for educational purposes. Also to check how strong the Unified Theory of Acceptance and Use of Technology (UTAUT) predictors were in predicting students and staff willingness to embrace IoT technology. The data was collected from 300 respondents through the use of an online questionnaire (google form). SPSS 25 and AMOS 26 were the statistical tools utilized to capture and evaluate the questionnaire data. Based on the research theoretical model and the research hypothesis, the empirical findings suggest that the factors of Performance Expectancy, Effort Expectancy, and Facilitating Condition positively influence Behavioral Intentions to use IoT technology, whereas Social Influence has no positive influence on Behavioral Intentions to use IoT technology for educational purposes in tertiary institutions in Kaduna state metropolis.

Authors: Musa M.I , Imam T.S
Published: April 2023

Hadejia-Nguru wetland has been known to be a productive area of Agricultural engagements and fisheries activities allowing for intensive farming and fishing activities, effluents from agricultural activities, sewage, and chemical seepages enter this water body. This study investigated the levels of several heavy metals Mercury (Hg), Lead (Pb), Cadmium (Cd),Chromium (Cr), and Aluminum (Al) in O. niloticus tissues (gills, liver, muscle) collected from five sampling sites in the study area. Tissue histology and the presence of antioxidant enzymes revealed the degree of tissue damage and stress in fish. The results for heavy metals showed concentrations in the order Hg>Cr>Pb>Al>Cd, which are higher than the maximum residue limits recommended by FAO and WHO. Superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA), and reduced glutathione (GSH) activities were observed at high concentrations in gills, liver, and muscle. Liver of the fish showed a high level of SOD concentration of 18.3μg/ml, followed by a concentration of 16.93 μg/ml in the gills, and CAT with a concentration of 1.48 U/ml was observed in the liver, MDA was highest in the liver with a concentration level of 1.08n/mol and there was no significant difference between MDA concentrations in liver and other organs (P < 0.05). Reduced glutathione levels of 18.36 μg/ml was seen in the liver of the fish. Histopathology of the select organs i.e. gills, liver and muscle cells showed that the organs of the fish were affected by the level of toxicity in the Hadejia-Nguru environment. The presence of metal toxicity, antioxidant enzymes, and tissue damage in fish is an indication of contamination and serves as a means for monitoring the safety of freshwater organisms.

The success of bio-fortification of cassava for production of vitamin A rich cassava granules commonly known as garri depends on the consumers’ acceptance. The study aimed at determining the quality of bio-fortified and traditional cassava granules. Four sample types were used for the study. This includes the bio-fortified sample and three traditionally prepared samples. The cassava granules samples were analyzed for functional properties, nutrient and anti-nutrient composition and sensory quality. Data obtained were subjected to analysis of variance (ANOVA) and means were separated using Duncan multiple range test. Results obtained indicated that there was significant (p<0.05) difference in the bulk density, swelling capacity and water holding capacity. Ijebu white cassava granules recorded the highest swelling capacity (3.80 %) while Ohafia cassava granules had the lowest swelling capacity (2.42 %). Ohafia cassava granules had the highest bulk density (0.65 g/cm3) and water absorption capacity (413.5 %) while the Ijebu white cassava granules had the least. The study revealed that Ohafia cassava granules had the highest crude fiber (7.10 %), ash (0.60 %) and moisture content (10.25 %). While the highest protein (2.59 %) and vitamin A (21.11 μg/g) were found in bio-fortified cassava granules There was significant difference in the moisture content, crude fiber, protein, ash and vitamin A. The hydrogen cyanide content of Ohiafia yellow cassava granules had the lowest value of 2.8 mg/kg while the Ijebu white cassava granules recorded the highest value (4.5 mg/kg). There was no significant (p<0.05) difference in the colour and the taste of the cassava granules samples. The Oyo white cassava granules followed by the fortified cassava granules were the most preferred for texture, aroma and overall acceptability. Bio-fortified cassava granules had comparative quality properties with the traditional cassava granules and could be beneficial in formulating diet rich in vitamin A and protein.

In this research, the blade element momentum (BEM) theory of a horizontal axis wind turbine (HAWT) blade with 1 kW power output has been analysed for one station across the six geopolitical zones. Twenty years wind speed data (2000 – 2020) obtained from Nigeria meteorological Agency (NIMET) Head quarter, Abuja. In an effort to optimally explore and utilize wind energy, an optimal design of wind turbine blade needs to be obtained. Therefore, a computational method to analysed and optimize the performance of the wind turbine blades needs to be developed. For that purpose, a computational method based on the Blade Element Momentum (BEM) theory is developed in this study. In this method, the blade of a wind turbine is divided into several elements and it is assumed that there is no aerodynamic interaction amongst the elements. Furthermore, this (BEM) method incorporated with equations from momentum and blade element theories to obtain equations which are useful in wind turbine blades design process. In this research a computed result for aerodynamic characteristics based on BEM theory shows that, Maiduguri Metropolis is suitable for surface wind electrification among the selected stations with an estimated maximum wind power of 1.774𝑘𝑊 at total lift to drag ratio (𝐹𝐿/𝐹𝐷) of 27.2674 and a mean relative velocity of 14.99m/s. There is an agreement with my findings and that of other researchers.

Developing potent adulticidal and larvicidal products for mosquito control remains a major control strategy for several mosquito-borne parasitic disease. The bio-efficacy of Hippocratea africana and Lasianthera africana methanol leaf extracts were assessed against the larvae of Anopheles gambiae. Plant extracts were shade dried at room temperature and powdered coarsely. Extracts concentrations used for larvicidal bioassays were 0.15, 0.30, 0.45, 0.60 and 0.75 w/v. Observations were made after 24, 48 and 72 h of exposure. The LC50 and LC90 of L. africana and H. africana against the larval of Anopheles species were determined. The larvicidal activities of both plant extracts increased as their concentrations and duration of exposure increased. The highest concentrations (0.75 w/v) of the extract of H. africana resulted in the highest mortality (85%) at 72 h. The highest concentrations (0.75 w/v) of the extract of L. africana resulted in 70% mortality. No death of larvae A. gambiae occurred in the control experiment. Mortality of A. gambiae larvae increased significantly as the concentration of the extracts were increased (r = 0.648, p < 0.0001). Increase in the mosquito larval mortality was significant for H. africana (r = 0.634, p = 0.005), and L. africana (r = 0.854, p < 0.0001), but H. africana was a more potent larvicide. This study has shown that leaf extract of H. africana and L. africana could be incorporated in the formulation of potent larvicides against Anopheles gambiae.

Published: April 2023

The forces of digital technologies are cohesive, penetrative and ubiquitous with the propensity to transform every human activity. Thus, the tempo of religious practices within the influence of this digital pull cannot remain unaffected. This study examines the influence of digital technologies on religious endeavours in the era of Global Information Culture (GIC), particularly on global missions and how humans cannot escape the glue. Descriptive and phenomenological techniques were adopted to x-ray the concepts. The study also identifies the roles of GIC in supporting socio-economic development, influencing cultural and cross-cultural practices, and affecting religious and inter-religious relationships. The study submits that innovations in the GIC have influenced spirituality and Christian witnessing in the 21st century and concludes that in the current webbed dispensation, humanity becomes techno-sapiens and remains so even in their religious practices. The paper, therefore, recommends that stakeholders in the religious sector and practitioners of mission need to embrace and imbibe GIC for their maximum output in their respective endeavours.
