Conducting night cardiorespiratory monitoring in patients with chronic obstructive pulmonary disease allows us to identify 4 clinical and pathogenetic variants of breathing during the night hours. The course of chronic obstructive pulmonary disease without obstructive sleep apnea syndrome in older patients with a long history of the disease, severe obstructive disorders and pulmonary hypertension can lead to nocturnal hypoxemia and poor quality of night sleep.. Patients with chronic obstructive pulmonary disease with obstructive sleep apnea syndrome and persistent nocturnal hypoxemia against the background of effective sipap therapy need additional low-flow oxygenotherapy during the night hours. Patients with severe chronic obstructive pulmonary disease without obstructive sleep apnea need low-flow oxygen therapy at night.

PUBLIC PERCEPTION AND USE OF URBAN GREEN SPACE (UGS): A STUDY FROM VADODARA, GUJARAT
Authors: Joshi Dr. Janak .P. , Bhatt Dr. Bindu.M.
Published: April 2023

Context/Background: The size and availability of urban green spaces (UGSs) are frequently considered among the most important parameters of the quality of life and environmental sustainability of urban areas. UGSs also offer direct benefits to urban residents, including but not limited to health promotion. Given the functional benefits of green spaces on human well-being in particular, it is important to understand how people perceive these spaces and their benefits.
Aims/Objectives: This research had a concern to situate issues of the benefits of green space amongst a broader exploratory study which explored the holistic experience of green spaces for contemporary city residents.
Methodology: The study was conducted for a sample of 300 adults (aged 16 and above) living in urban areas of Vadodara across the representation available of gender, education, and professional background The interviews were conducted face to face, on weekends, weekday evenings, and other times when visitors were in large numbers . The responses were converted into frequency and percentage.
Results: Amongst the visitors, it is seen that a lesser proportion of women visitors visit the park than men. Visitors value urban green spaces most for ‘environmental’ and ‘psychological and health. Service class visit for health benefits while business persons for socializing. A majority of respondents are happy with UGS quality. The visitors accompanied by family members as parks are attractive places for recreational activities with families and contribute to improved social interaction. Residents of the most active ages (25–55) tend to make shorter trips.
Conclusions: The contributions of urban green spaces to community health and well-being can be through improvements in ambient environmental quality, more opportunities for healthy lifestyles, and opportunities to come in contact with nature.

Supernova Dust Evolution Probed by Deep-sea 60Fe Time History
Authors: Ertel Adrienne F. , Fry Brian J. , Fields Brian D. , Ellis John
Published: April 2023

There is a wealth of data on live, undecayed 60Fe (t
1/2 = 2.6 Myr) in deep-sea deposits, the lunar regolith, cosmic rays, and Antarctic snow, which is interpreted as originating from the recent explosions of at least two near-Earth supernovae. We use the 60Fe profiles in deep-sea sediments to estimate the timescale of supernova debris deposition beginning ∼3 Myr ago. The available data admits a variety of different profile functions, but in all cases the best-fit 60Fe pulse durations are >1.6 Myr when all the data is combined. This timescale far exceeds the ≲0.1 Myr pulse that would be expected if 60Fe was entrained in the supernova blast wave plasma. We interpret the long signal duration as evidence that 60Fe arrives in the form of supernova dust, whose dynamics are separate from but coupled to the evolution of the blast plasma. In this framework, the >1.6 Myr is that for dust stopping due to drag forces. This scenario is consistent with the simulations in Fry et al. (2020), where the dust is magnetically trapped in supernova remnants and thereby confined around regions of the remnant dominated by supernova ejects, where magnetic fields are low. This picture fits naturally with models of cosmic-ray injection of refractory elements as sputtered supernova dust grains and implies that the recent 60Fe detections in cosmic rays complement the fragments of grains that survived to arrive on the Earth and Moon. Finally, we present possible tests for this scenario.
Phylogeny and classification of Endromidae (Lepidoptera: Bombycoidea) based on mitochondrial genomes
Authors: Deng Min , Zwick Andreas , Chen Qi , Liao Cheng-Qing , Wang Wei , Wang Xing , Huang Guo-Hua
Published: April 2023

The small, relict-like moth family Endromidae is well-established within the superfamily Bombycoidea, but relationships within the family have remained vague for the last decade, primarily due to very limited taxon sampling. This resulted in the explicit removal of all internal suprageneric classification by Zwick et al. (2011) when they synonymized Mirinidae and the bombycid subfamilies Oberthueriinae and Prismostictinae with Endromidae. Nucleotide and amino acid data sets of the 13 mitochondrial, protein-coding genes from representatives of 13 of the 16 accepted endromid genera were used to estimate phylogenetic relationships based on maximum likelihood and Bayesian inference methods. The results strongly support Endromidae as a monophyletic group and enable the establishment and diagnosis of four subfamilies (Endrominae, Mirininaestat. rev., Oberthueriinaestat. rev. and Prismostictinaestat. rev.). Within subfamily Oberthueriinae, we establish three tribes: Oberthueriinistat. rev., Andracinitribe nov. and Mustiliinitribe nov. We provide morphological diagnoses and a genus-level checklist for the three tribes. Promustilia yajiangensis Wang, X. & Zolotuhin, 2015 is transferred to Mustilizans as M. yajiangensiscomb. nov. to establish reciprocal monophyly of the two genera, and Andraca gongshanensis is transferred to Pseudandraca as P. gongshanensiscomb. nov. We also synonymize Andraca (Chrypathemola)syn. nov. with Andraca (Andraca), as the latter is deeply nested within the former.

Action Cœur de Ville : la proximité pour développer durablement nos territoires
Authors: Mouchel-Blaisot Rollon
Published: April 2023

Pendant cinq décennies, on a trouvé pertinent d’éloigner de plus en plus nos concitoyens des emplois, commerces, services et activités. Ce modèle urbain isolant les habitants, vidant nos beaux cœurs de ville et détruisant nos espaces naturels, agricoles et forestiers a implosé, car insoutenable économiquement, écologiquement et socialement. C’est en réaction à cette vision mortifère que le programme national Action cœur de ville a été imaginé en 2017, afin de soutenir les villes dites moyennes en redynamisant leur cœur de ville, en stoppant l’étalement urbain et en ré-imaginant une ville plus attractive, naturelle et inclusive, pour tous. Le caractère transversal d’Action Cœur de Ville, politique prioritaire du gouvernement quasiment coconstruite avec les destinataires, vise à répondre au mieux aux projets des collectivités portés par les maires, au plus proche des préoccupations et envies des habitants et des acteurs locaux. Ainsi, ce programme national, s’appuyant sur des collectivités dynamiques formant un réseau territorial unique en Europe, est pleinement mobilisée sur les défis des trois grandes transitions de notre temps : écologique, économique et démographique. C’est dans et avec les territoires que les solutions pourront être trouvées.
Les mobilités au cœur de la transition sociale-écologique
Authors: Mayer-Rossignol Nicolas
Published: April 2023

Pour la Métropole de Rouen Normandie, dixième métropole de France avec plus de 500 000 habitants et 71 communes, les mobilités sont l’un des principaux leviers de la transition écologique en conciliant décarbonation des transports et inclusion sociale dans les espaces urbains comme ruraux. Cette stratégie s’appuie sur différents axes comme le renforcement récent de l’offre de transports en commun, le développement du covoiturage, l’augmentation de la part du vélo, la montée en capacité des parkings relais permettant de faire le lien entre les différentes parties du territoire, la sécurisation du stationnement des vélos et de nombreuses autres mesures. La métropole rouennaise représente par les entreprises et laboratoires implantés sur le territoire un écosystème très favorable d’innovations pour les mobilités de demain : l’arrivée prochaine de l’entreprise néerlandaise Ebusco, fabricante de bus électriques, qui va installer dans la métropole son siège social français ainsi qu’un établissement de production d’envergure européenne en est une illustration.
Dans les grandes régions, le préfet de région éloigné des territoires conduit à la renaissance du préfet de département
Authors: Cochet Arnaud
Published: April 2023

Si le décret du 16 février 2010 a partagé les rôles entre préfets de région et de département, des matières restent propres au niveau départemental. Depuis 2019, année de la réforme de l’organisation territoriale de l’État, l’échelon départemental et l’accroissement de ses pouvoirs de gestion a été renforcé. Plus récemment, depuis 2022, la loi relative à la différenciation, la décentralisation, la déconcentration et portant diverses mesures de simplification de l’action publique locale crée la possibilité pour le préfet de région de déléguer sa signature au préfet de département. Dans le même mouvement, les préfets de département se voient confier le rôle de délégués de nombreuses agences et l’on assiste depuis quelques années à un dépassement de cet échelon à travers le rôle croissant dévolu aux sous-préfets d’arrondissement. La proximité apparaît comme indispensable dans la conduite des politiques publiques au service des citoyens locaux et conforte de fait l’échelon départemental et intradépartemental.

Le rôle de la transmission intergénérationnelle de l’esprit d’entreprise dans la performance : cas des entrepreneurs du secteur informel au Cameroun
Authors: Abbo Mohamadou , Sangué-Fotso Robert
Published: April 2023

La prédominance des entreprises de l’informel contraste avec la rareté des travaux dans les économies africaines. S’appuyant sur la théorie de l’effectuation, ce travail a pour objectif d’examiner la transmission intergénérationnelle de l’esprit d’entreprise des unités de production informelle (UPI) sur la performance. À partir de la base de données de la deuxième Enquête sur l’Emploi et le Secteur Informel (EESI 2) portant sur 3 560 entrepreneurs, des analyses ont été effectuées sur la base de la méthode des moindres carrés ordinaires (MCO). Les résultats montrent que les entrepreneurs informels dont la mère exerçait une activité d’entrepreneur ont un avantage qui s’explique par la transmission de compétences managériales et par la transmission d’un capital social. Cet avantage est encore plus important sous l’influence d’autres facteurs liés à l’entrepreneur de l’informel comme la polygamie, la religion, l’existence des salariés et l’expérience. Les résultats contribuent au renforcement de la littérature sur la transmission intergénérationnelle de l’esprit d’entreprise en identifiant les caractéristiques liées à l’entrepreneur qui améliorent la performance.
Krasnoselskii-type results for equiexpansive and equicontractive operators with application in radiative transfer equations
Authors: Ahmad Niaz , Mehmood Nayyar , Abdeljawad Thabet , Mukheimer Aiman
Published: April 2023

In this paper, we study the results of fixed points for the operator equations of type $ x = H(\digamma x, x) $ using the idea of measure of noncompactness and assuming that the operator $ \digamma $ is $ k $ -set contractive (strictly $ k $ -set contractive, or a continuous) and the family $ \{H(u, .):u\} $ is equiexpansive or equicontractive. The obtained results are generalization of Krasnoselskii type fixed point results. Some examples are given to elaborate new concepts. We use the main result to find the existence of solutions for the stationary radiative transfer equation in a channel. We demonstrate our theory with an example by comparison of an approximate solution with the exact solution.

This paper presents the proofs of the higher integrability and regularity of weak solutions to a class of variation-inequality problems that are formulated by a non-Newtonian parabolic operator. After obtaining the gradient estimate, the higher order integrability of the weak solution is analyzed. We also examine the internal regularity estimate of the weak solution by utilizing a test function of the difference type.
Impact of Organizational and Supervisory Support Perceptions on the Turnover Intentions of Working Mothers-to-Be
Authors: Agarwal Bhawna , Nelson Merlin Mythili
Published: April 2023

The purpose of the paper is to examine the various factors that influence turnover intentions of working women at the threshold of motherhood. The impact and interrelationships of variables like organisational and supervisory support perceptions, flexible-work-options, work-family conflict, job and family satisfaction, and their effect on turnover intentions are examined. A questionnaire survey of 203 working women of three categories—women undergoing infertility treatment, pregnant women, and new mothers of the Indian IT sector—was conducted and hypotheses tested through structural equation modelling. Results validated the model developed and confirmed the causal relationships whereby employees working in family-supportive work environments experienced lower levels of work-family conflict, and reduced work-family conflict thereby led to greater job and family satisfaction followed by lesser turnover intentions. The study reiterates the need for organisations to offer specific policies that allow working-women to continue their careers as they go through motherhood.

The study aims to explore the online attention received by the top twenty highly cited publications on plagiarism published between 2011 to 2020 from India by using the observation method. The bibliographical data were collected from SCOPUS database and the altmetric data were collected by using the altmetric harvesting tools AltmetricIt and PlumX. The study's findings show that the citation count and the Altmetric Attention Score of the top twenty highly cited publications on plagiarism published between 2011 to 2020 from India are much lower than those from other countries. The Spearman correlation analysis of the citation count and AAS shows that they are not correlated. The study hopes that in the future, the publications to be published from India on important subjects such as plagiarism will have a more significant online impact on the research community and will help the authors and the publishers to understand the current status of the popularity of their research publications and the impact they have made on the research community.
The State of Ethical AI in Practice
Authors: Hinton Charlene
Published: April 2023

Despite the prolific introduction of ethical frameworks, empirical research on AI ethics in the public sector is limited. This empirical research investigates how the ethics of AI is translated into practice and the challenges of its implementation by public service organizations. Using the Value Sensitive Design as a framework of inquiry, semi-structured interviews are conducted with eight public service organizations across the Estonian government that have piloted or developed an AI solution for delivering a public service. Results show that the practical application of AI ethical principles is indirectly considered and demonstrated in different ways in the design and development of the AI. However, translation of these principles varies according to the maturity of the AI and the public servant's level of awareness, knowledge, and competences in AI. Data-related challenges persist as public service organizations work on fine-tuning their AI applications.
Thixotropic Magnetorheological Fluid for Controlled Vibration Mounts
Authors: Gordeev B. , Ermolaev A. , Titov E.Yu. , Titov D.Yu.
Published: April 2023

The article is devoted to the development of the composition of a thixotropic magnetorheological fluid and a laboratory setup for determining the properties and characteristics of magnetorheological fluids. The magnetorheological fluid was developed on the basis of copolymers of methyl methacrylate and n-butyl methacrylate, a mixture of diethylbenzenes, dioctylphthalate, oleic acid, and carbonyl iron of the P-10 grade. To impart thixotropic properties to the magnetorheological fluid, a 1% solution of modified urea is added. For the study of magnetorheological materials, a laboratory setup was developed that allows one to measure the yield stress, plastic viscosity, flow curves, magnetorheological characteristics and the magnetization curve. The setup includes two hydraulically connected cylindrical vessels and one external cylindrical vessel filled with the investigated magnetorheological fluid between two poles of a powerful magnet. The shear stress is determined through the magnitude of the viscous friction force that occurs when a load immersed in the liquid is evenly lifted, and the strength and induction of the magnetic field are determined by means of two Hall sensors.
Integration of System Reliability Theory into Quantitative Risk Assessment
Authors:   Sikorsky a Lockheed Martin Co., Hewitt John , Pham Loan
Published: April 2023

Quantitative Risk Assessment has become essential for rotorcraft safety risk management. A major objective of Quantitative Risk Assessment (QRA) is to predict the number of future events (risk projection) associated with a hazard. QRA is a datadriven mathematical and statistical process that typically involves a specific failure mode of a single component. However, there are cases of component multiplicity e.g. multiple instances of a specific component on one aircraft whose interdependency would impact the risk projection. In such cases, a comprehensive system reliability approach needs to be integrated with QRA to accurately forecast future risk.
Intelligent Helipad Detection from Satellite Imagery
Authors:   Rowan University, Specht David ,   FAA William J. Hughes Technical Center, Johnson Charles , Bouaynaya Nidhal , Rasool Ghulam
Published: April 2023

Location data about U.S. heliports is often inaccurate or nonexistent in the FAA's databases, which leaves pilots and air ambulance operators with inaccurate information about where to find safe landing zones. In the 2018 FAA Reauthorization Act, Congress required the FAA to collect better information from the helicopter industry under part 157, which covers the construction, alteration, activation and deactivation of airports and heliports. At the same time, there is no requirement to report private helipads to the FAA when constructed or removed, and some public heliports do not have up to date records. This paper proposes an autonomous system that can authenticate the coordinates in the FAA master database, as well as search for helipads in a designated large area. The proposed system is based on a convolutional neural network model that learns optimal helipad features from the data. We used the FAA's 5010 database and others to construct a benchmark database of rotocraft landing sites. The database consists of 9,324 aerial images, containing helipads, helistops, helidecks, and helicopter runways in rural and urban areas, as well as negative examples, such as rooftop buildings and fields. The dataset was then used to train various state-of-the-art convolutional neural network models. The outperforming model, EfficientNet-bθ, achieved nearly 95% accuracy on the validation set.
Gli ammonoidi della Formazione di Besano pubblicati da Airaghi nel 1912 conservati al Museo Kosmos di Pavia
Authors: Pieroni Vittorio
Published: April 2023

Ammonoids from the Besano Formation published by Airaghi in 1912 kept at the Museo Kosmos in Pavia. The ammonoids from the Besano Formation described by Airaghi in two works in 1912, belonging to the collections of the Museo di Storia Naturale di Milano, as well as many other historical collections stored in this museum, have been lost during World War II. However, some plaster casts of these specimens were recently found among the material stored in the new Museo Kosmos in Pavia during a reorganization of the deposits. The plaster casts, probably made by Airaghi, were obtained from the original specimens corresponding to some species erected by Airaghi and coming from the mine of Tre Fontane (Mt. San Giorgio, Switzerland). Lacking original specimens and related stratigraphic data, the present material is herein reclassified and considered as complementary for the corresponding neotypes, previously stated by Rieber in 1973. Among the taxa not revised in literature, two new combinations are here proposed: Serpianites marianii (Airaghi 1912) and ?Nevadites bassanii (Airaghi 1912). With these plaster casts we also uncovered some original specimens never described. The majority of the material is paired with the original labels by Airaghi. These ammonoids are characteristic of the lower and upper Secedensis Zone (Upper Anisian, Middle Triassic) of the Besano Formation. It is very likely the herein described specimens were collected in the beds belonging to the Secedensis Zone of the mine Tre Fontane which have been completely removed in the first years of excavation activity.

Generic structure potential analysis of Christian street evangelism in Southwestern Nigeria
Authors: Ajayi Michael T.
Published: April 2023

Christian street evangelism is one of the Bible-based doctrinal practices found among Nigerian Christians, especially in Southwestern Nigeria. Studies have examined language use in Christian activities, including sermons in church services, at funerals and in marriage ceremonies. However, no scholarly attention has been paid to a linguistic description of language use in Christian street evangelism, which, although sit hares some features with other contexts of Christian activities, manifests some elements that characteristically define it within the series of Christian evangelistic activities. This study, therefore, is a generic structural potential analysis of Christian street evangelism in Southwestern Nigeria. Data were gathered using ethnographic techniques. Data comprised fifteen observed street evangelism activities randomly sampled in different cities in Southwestern Nigeria. Data were subjected to discourse analysis within the purview of Halliday and Hassan’s (1985) Generic Structure Potential (GSP) theory. Findings reveal Christian street evangelism features five obligatory elements: songs, greetings, sermon, prayer and finis; and three optional elements: declaration of purpose, call for confession, and welcome to the fold.

Published: April 2023

Since 1982, the olfactory system of creatures has piqued the interest of academics who seek to create a comparable system. Despite its mysterious nature, the first stage has been successfully completed with the development of the E-nose. Its extended applications have opened new doors for researchers, ranging from food quality testing to bomb detection and even, more recently, identifying those infected with the coronavirus. In this talk, we will review the structure and sensor behavior of the E-nose, as well as its applications, such as odour source localization and various applications in agriculture. The challenge of odour identification has prompted researchers to employ robots with sensors to investigate and locate odour sources. The present study aims to synthesize documented research and provide a fresh perspective on odour localization research efforts and tests conducted. The study highlights previous attempts to equip robots with sensors to explore the real indoor or outdoor environment. Initially, a review was conducted to investigate various aspects of the sector and the obstacles involved.

MoveNet has been employed to extract the anatomical key points from RGB video frames. Different subjects from different camera angles were employed to make the approach person-independent. Diverse Machine learning models such as Decision tree, support vector machines, XGboost, and random forest classifiers were employed using extracted keypoints for training the model for estimating human activity during posture estimation monitoring. SMS are sent to the designated person with the raising of buzzer alarm in case of anomalous behaviour detection.
Deep Biased Matrix Factorization for Student Performance Prediction
Authors: Huynh-Ly Thanh-Nhan , Le Huy-Thap , Thai-Nghe Nguyen
Published: April 2023

In universities that use the academic credit system, selecting elective courses is a crucial task that can have a significant impact on a student's academic performance. Students who perform poorly in their courses may receive formal warnings or even face expulsion from the university. Thus, a well-designed study plan from a course recommendation system can play an essential role in achieving good academic performance. Additionally, early warnings regarding challenging courses can help students better prepare and improve their chances of success. Therefore, predicting student performance is a vital component of both the course recommendation system and the academic advisor's role. To this end, numerous studies have addressed the prediction of student performance using various approaches such as association rules, machine learning, and recommender systems. More recently, personalized machine learning approaches, particularly the matrix factorization technique, have been used in the course recommendation system. However, the accuracy of these approaches in predicting student performance still needs improvement. To address this issue, this study proposes an approach called Deep Biased Matrix Factorization, which carries out deep factorization via multi-layer to enhance prediction accuracy. Experimental results on an educational dataset have demonstrated that the proposed approach can significantly improve the accuracy of student performance prediction. By using this approach, universities can better recommend elective courses to their students as well as predict student performance, which can help them make informed decisions and achieve better academic outcomes.

Amphibian skin is extremely permeable to environmental contaminants and their health is inextricably linked to environmental health. Hence the objective of this study was to evaluate the level of pesticide contamination in amphibian tissues and their environment (soil and sediment) at Ojo Camp-Ugboke cocoa plantations in Edo State, southern Nigeria using HP 5890 series gas chromatography system coupled with an Electron Capture Detector (ECD). Data obtained showed that thirteen organochlorine pesticides, one triazine herbicide, carbamate, and organophosphate were found in high concentrations. All pesticides components were detected in amphibian tissues, most with higher concentrations than other samples. The high permeability of amphibian skin is responsible for the detected in-tissue concentrations. Pesticide residues in amphibian tissues are not only harmful to their health, but also pose a health risk to those who consume amphibian meat as a delicacy. Local farmers' unabated/unregulated use of pesticides may contribute in amphibian population decline. For a healthier environment, it is best to increase public awareness while also supporting routine monitoring and regulation by relevant agencies.

The effect of ternary mixtures of polycyclic aromatic hydrocarbons in Clarias gariepinus was investigated. Apparently healthy juvenile fish (n = 90) weighing 19.7±1.8 g were exposed to sublethal concentrations of naphthalene, phenathrene and benzo[a]pyrene over a period of 35 days after which liver biomarker analyses were carried out on blood plasma fraction. The observed total plasma protein was 35.1 g/L while the albumin and total bilirubin concentrations were 15.9 g/L and 4.6 μmol/L respectively. The plasma concentrations of the liver enzymes were 25.27 IU/L, 9.37 IU/L, and 28.01 IU/L for alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP) respectively. While there were significant declines in plasma total protein and albumin, significant elevation was observed in plasma total bilirubin. Significant increases were also observed in the activities of the liver enzymes, alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP). Exposed liver and gill sections showed histopathological alteration. There was steatosis accompanied with moderate dense infiltrates in the liver while the gills showed channel dilatations with hyperplasia. Findings from this study suggest that PAH mixtures cause changes in the activities of liver metabolic enzymes as well as alter the normal architecture of liver and gills in exposed aquatic organisms.

The challenge of environmental toxicity and the associated unrelenting efforts of man to abate or eradicate its hazards are lifelong efforts. The present study investigated the impact of Ikhueniro dumpsite leachate in Benin City, Nigeria on the hematological blood profile and blood film of Wistar rats. A total of 30 Wistar rats were acclimatized for two weeks and randomly distributed into three groups A to C; group A served as control, while groups B and C were orally administered Leachate only and Leachate + Abatement (Dialium guineenses aqueous leaf extract), respectively, once every 48 hours for 30 days. After the exposure period, the surviving rats in group A and half of the rats in group B and C were examined and sacrificed. The experiment continued with the remaining rats in groups B and C. Group B was given only clean water and C only abatement  following ealier stated schedule, after which the surviving rats were sacrificed and samples collected. Hematological analysis showed that leachate administration in Wistar rats caused an increase in white blood cells (27.65%), platelet count (13.35%), and platelet crit (45.45%); with a decrease in red blood cell count (7.52%), hemoglobin (5.40%) and hematocrit (6.12%) of Wistar rats when compared to the control. Geimsa-stained blood film revealed the presence of polymorphs and basophils in the blood film of rats administered dumpsite leachate. Nevertheless, when leachate administration was stopped in the group of rats where it was previously administered, there was a slight improvement in some blood hematological indices. However, the administration of Dialiumguineense leaf extracts better-improved blood hematological indices. The findings of this study indicate that Ikhueniro dumpsite leachate negatively impacted blood hematological indices in Wistar rats. Dumpsite leachate should be handled and treated carefully to avoid potential health hazards in animals.

Published: April 2023

The study examined the effectiveness of linkage mechanism in community development activities (CDAs) in Edo State Nigeria using Data collection through structured questionnaire administration to157 local leaders and 31 extension agents. Results shows obtained show that informal linkage mechanisms like social gathering (18.5% and 22.6%) was very low among local leaders and extension agents while 21.0% of local leaders and all (100%) sampled extension agents used community visits and joint problem identification. Majority (66.6% and 75.0%) of local leaders and extension agents perceived use of linkage mechanisms effective in community development activities. 77.1% of local leaders and 77.4% of the extension agents indicated incompatibility of government policies as serious(% ≥ 50) constraint in the use of linkage mechanism in CDAs by local leaders and the extension agents. Significant difference existed between effectiveness of linkage mechanisms between local leaders ( = 43.15) and extension agents (  = 21.86) in facilitating community development activities in the study area as t-test value obtained was 6.72. The study recommends effective linkage mechanism in community development activities; community developers encouraged and assisted through the formulation of compatible policies which would enhance and promote use of linkage mechanisms in community development activities/efforts.

Published: April 2023

The objective of this study was to extract oils from seeds and seed shells of Trichilia dregeana growing in Ethiopia. The oils were extracted using Soxhlet extraction technique and an organic solvent (n-hexane). The yields of the oils were in the range of 39.64-55.4%. The physicochemical properties of the oils such as density, acid value, saponification value and peroxide values were 0.8 ± 0.004 -0.84±0.014g/mL, 0.039±0.004 -5.667 mg KOH/g, 75.82±0.0 - 102.01±0.0 mg KOH/g and 0.01±0.01-0.0182±0.0, respectively. The results showed that all the observed physicochemical data of the oil products to be consistent with literature reported data for oils from seed crops and seeds of Trichilia species. GC-MS analyses also showed that all the oils contain palmitic acid (14-69%). Oleic acid and Linoleic acids were also found in different amounts. Elaidic acid was found (86%) only in one seed shell extract. Soaps were prepared using the extracted oils and alkali solution via saponification process. The properties of the soaps were found to be 9.10-9.81, 8-25.5% and 0.373-0.682 for pH, moisture contents and total alkali contents, respectively. These data and the data for foam and cleaning abilities of the prepared soaps were found to be in the acceptable limit. The results also suggested that Trichilia dregeana seeds and seed shells are rich in oils. High yields of oils from seeds and seed shells suggest their future potential in soap making and also as inputs for biofuel production. This could have significant contribution to economy of a given community where the plant grows in abundance.

Published: April 2023

This study examines the activities of alanine aminotransaminase (ALT) and aspartate aminotransferase (AST) in the liver of 30 adult Wistar rats exposed to nutmeg for 30 days. 1 g of nutmeg was administered to group A (n=10), 2 g of nutmeg to group B (n=10) and group C (n=10) was used as the control. Enzyme activities were assayed in both serum and liver (tissue homogenate) spectrophotometrically. Results obtained showed a significant increase (p < 0.05) in level of AST in serum of rats in group A and B (20.2±7.29 and 23.2 ± 3.27 U/L) when compared to the control group (14.8± 1.78 U/L) while serum ALT level was significantly reduced (5.2± 1.78 and 4.2 ± 0.04 U/L) compared to the control group (7.0 ± 2.6 U/L) but the differences based on dosage was statistically insignificant (p≥ 0.05). The enzyme activities in liver tissue homogenate showed a significant increase (p˂ 0.05) in AST levels (13.8 ± 1.14, 14.6 ± 1.78 and 12.8 ± 0.08 U/L) among test groups and between controls but ALT levels though lower in treated groups than control, was statistically insignificant (p≥ 0.05) among test and between control group (4.6 ± 1.34, 4.0 ± 0.08 and 5.8 ± 0.03 U/L). Differences in enzyme activities due to nutmeg administration may lead to hepatocellular injury as well as myocardial infarction. The results suggests that dosage and long-term consumption of nutmeg could have severe health implication as it affects liver function as well as other associated organ of the body.

Published: April 2023

Bread is one of the basic and popular foods consumed by the majority of the Nigerians irrespective of their ethnic or socioeconomic status. Potassium bromate (KBrO3) is well known bread enhancer. Because of its negative health effects it has been banned in Nigeria and other countries. This paper aims to reviews studies on the use of KBrO3 in bread to ascertain the safety of the bread products and to also evaluate bakers’ compliance with specified regulations. The paper also assesses the possible reasons for the use of KBrO3 by the bread bakers (intentional or unintentional?) as well as addressed what regulatory bodies need to do to improve the bakers’ compliance. Fourty seven (47) articles were evaluated and 95.74% of them reported the presence of potassium bromate in the bread samples analysed, which suggests that use of Potassium bromate in bread production in Nigeria is very common and breads sold in Nigeria are unsafe for human consumption. This high usage may be attributed to factors such as bromine in wheat flour, adulterated improvers or due to use of brominated flour. Also, economic gain, high cost of ingredients and poor enlightenment and enforcement may also be contributing factors. Therefore, regulatory bodies need to adopt strategies such as Post-marketing Surveillance (PMS), on the-spot analysis, effective monitoring and enforcement, stringent regulations, and sustained routine and surveillance inspections to at least reduce, if not eliminate, the use of KBrO3 as bread enhancer.
