Authors: Nathaniel Wanmi , Onoja Benedict , Shawulu Clinton , Jibrin Imam
Published: August 2022

Demand for dog is on an increase because they are used as watchdog, hunting and its breeding serves as a source of income to both rural and  urban dwellers. As demand is increases, breeders often mate dogs at premature age thereby causing several complications from conception to  birth. This study was aimed at considering the post-natal development of the uterus from histomorphological aspects and to correlate features to  attainment of puberty. Hysterectomy was carried out to secure the uterus from Day 2, Week 4, Week 8, Week 12 and Week 20. This developmental  study attempted highlighting some silent microanatomical parameters, including the circular muscle, longitudinal muscle, myometrial glands,  blood vessels and epithelial features of the uterus in the Nigerian indigenous bitch. The inner circular muscle and the germinal epithelium were the  first microstructures to be observed on day 2 and week 4 of postnatal development respectively. Within these range of development, little or no  histological variations occurred. Simple columnar epithelium and longitudinal smooth muscle were seen on the twelfth week. The inner circular  muscle and outer longitudinal muscles made up the fundamental component of the smooth muscle. The significant of this study is to indicate  histological changes that takes place within the uterus and this finding show some corresponding relationship that exist between age and uterine  development, an indicator for determining puberty.

Oestrogens are steroid hormones that influence the growth, differentiation, and functioning of many target organs, including the male and female  eproductive organs. Menopause, an important sign of aging in women is characterized by oestrogen depletion, which is associated with many  menopausal problems. Oestrogen supplements that are mostly used are not readily safe and have been reported to cause serious health hazards  Phytoestrogens are plant compounds that are essentially correspondent to oestradiol (17-β oestradiol) and can relate with oestrogen receptors to  elevate and/or prohibit oestrogenic responses. This study therefore aimed at evaluating the possible therapeutic efficacy of Allium sativum and  Allium cepa on oestrogenic activities of adult ovariectomised wistar rats. Adult Wistar rats were ovariectomized, then administered various doses of  the extracts for 28days, then sacrificed and tissues harvested for analysis. Results shows Allium cepa and quercetin to increase endometrial  thickness, increase neural cells in synaptophysin stained cells of hippocampus and dentate gyrus. A conclusion of Allium cepa possessing similar  strogenic properties as estradiol group in these ovariectomized  rats was drawn, which can offer some ameliorative effects of estrogen deficiency.

Published: August 2022

Calvarial intrasutural bones (CIB) incidences are known to vary in different populations. The objective of this study was to determine the frequency,  location, number and gender difference if any, of CIB in Nigerian skulls. This descriptive observational study included 96 adult skulls. Out of 96  subjects, 58 were males and 38 were females (M:F=1.5:1). The mean age was 50.2±16.5 years (19-83 years). Most of the skulls studied (56%) had CIB.  Sixty percent of the males and 50% of the females had CIB (p=0.318). The lambdoid suture (33.3%) and lambda (20.8%) area were the most common  sites for CIB. When present, CIB were mainly on the right (43.8%). The bregma, pterion and coronal suture were rare sites for CIB in this study population. These results established that CIB are common in adult Nigerian skulls and that there is no significant association between presence of  CIB with gender or age. This variation should be taken into consideration in patient evaluation and surgical planning.

Published: August 2022

Reoccurring Fulani-farmer crisis in Nigeria as a result of the destruction of farmland and arable crops by cattle during grazing has led to a high rate of loss of life and properties. To address this problem, this research work proposed a shape- based ANN-Fourier descriptor cattle recognition system. Twenty samples of each of cattle, deer, dog, elephant, horse, and camel were obtained from the UCL database. Colour space conversion and a simple image binarization were performed to obtained image segmentation. Edges of the images were extracted, and Discrete Fourier Transform was applied on the edges to obtain the Fourier descriptors. Ten Fourier descriptors were used to train feed-forward back propagation artificial neural networks for cattle recognition systems. The effect of increasing database size, the number of images used for training and testing, and threshold value were investigated. It was observed that there was no effect of increasing the size of the database on the system performance. For better accuracy, sensitivity, specificity, and precision, it was observed that a good threshold value must be carefully chosen and 75% of the image must be used for training and 25% for testing respectively. With twenty image samples, each for cattle, deer, camel, dog, horse, and elephant in the database, fifteen out of twenty samples were used for training, five for testing, and the threshold value of 0.6, 98.7% sensitivity, 98.8% specificity, 98.8% accuracy and 94.5% precision were achieved. This result provides a good method for cattle detection and recognition system.

Newcastle Disease Virus (NDV) constitutes a major constraint to the poultry production system in Nigeria. This study was carried out to investigate the seroprevalence of NDV antibodies in local chickens (Gallus domesticus) slaughtered in five different live bird markets (LBMs) in Kaduna metropolis, Nigeria. Three hundred blood samples were collected and screened for antibodies against NDV using Haemagglutination Inhibition (HI). An overall seroprevalence rate of 23% (95%:CI18.5-28.0) was recorded in this study. Seroprevalence based on different LBMs revealed a higher prevalence of 28.3% (95% : Cl 18.0-40.7) in Sabo market, followed by Sokoto road market 26.7% (Cl:16.7-38.9), Kawo market 18.3% (95% Cl: 10.0-29.6), Railway market 13.3% (Cl:6.4-23.5), and the lowest prevalence was recorded in central market 11.7% (Cl:5.2-21.7). The difference in seroprevalence among the LBMs was not statistically significant (p > 0.05). Higher seroprevalence of NDV antibodies in female birds 30.5 % (Cl: 24.1-37.6) was recorded compared to male 13.9% (Cl: 8.3-21.4). The study indicated that NDV is endemic in the population. LBMs location had no significant influence on the seroprevalence of NDV in the study area. The difference in seroprevalence between sexes was statistically significant (p < 0.05). Therefore, this study demonstrated the need for a regular strategic vaccination programme against NDV in local chickens in Kaduna metropolis.

Vernonia glaberrima plant is used traditionally in the treatment of cancer, diabetes and malaria in North central Nigeria. This study was designed to evaluate the cytotoxic effect of chloroform extract of Vernonia glaberrima and isolate some bioactive constituents. Neutral red cytotoxicity assay was performed using breast cancer (MCF7), cervical cancer (HeLa) and Liver cancer (HepG2) cells upon exposure to predetermined concentrations of the chloroform extract. The cell viability was determined colorimetrically after 72 hours of incubation. The extract was fractionated using silica gel column chromatography and preparative TLC. Isolated compounds were characterized using FTIR and NMR spectroscopy. The extract inhibited 50% cell proliferation of MCF7, HeLa and HepG2 cells at an IC50 value of 14.02 ± 0.03, 15.78. ± 0.04, and 16.77± 0.1 μg/mL, respectively. Two compounds namely, lupeol (1) and betulinic acid (2) were isolated from the extract. The two isolated compounds have been previously reported in literature to possess anticancer activities. Hence, the findings from this study demonstrate the potential anticancer properties of chloroform extract of Vernonia glaberrima.

There is strong evidence linking low glycaemic diets and reduced risk of developing diabetes mellitus (DM). This study was designed to develop low glycaemic index (GI) food using rice. Rice was subjected to enzymatic treatment at 40 °C for 8 mins for destarching. After the incubation, the proximate composition and GI of the processed rice were determined. Proximate analysis was carried out using the standard methods of AOAC, whereas GI was assessed using a postprandial oral glucose test. The results showed a significant reduction (p < 0.05) in percentage carbohydrates in the processed rice compared with the unprocessed control. Other parameters such as % moisture and lipids were also reduced in the processed rice when compared with the unprocessed control. Furthermore, the percentage of proteins and fibres were significantly increased in the processed rice compared to the unprocessed control. The GI of the processed rice was 69.86% as against the 86.43% of unprocessed rice, representing a 16.57% reduction. Overall, the results suggest that the enzymatic treatment of the rice have the potential of reducing both the starch content and GI of the rice. This can be explored in the development of a diabetic diet.

Land use, land cover (LULC) change technique is essential for measuring ecological quality, environmental sustainability, and uncontrolled development at various spatiotemporal scales. To construct effective land use management plans, the probable future scenario of LULC changes can be easily detected utilizing a simulation technique.This study monitors and models spatiotemporal land-use changes in Okomu National Park over two decades (2000 – 2020) to project forest cover changes for the near future. A probabilistic cellular automata (CA) model was created and used to simulate land-use changes with the aim of predicting future land-use scenarios. Landsat7 ETM+ satellite images for years 2000, 2005, 2010, 2015, and 2020 were classified into Forest and Non–Forest using a maximum likelihood supervised classification algorithm. A probabilistic cellular automata model using Moore’s neighborhood with a Von Neumann extension was used to simulate land-use changes for years 2005, 2010, 2015, and 2020 with the year 2000 as the base year.The overall classification accuracy for the years under study was 98.18%, 97.52%, 96.33%, 91.67%, and 94.61%with overall kappa coefficients of 0.97, 0.96, 0.95, 0.86, and 0.91 respectively. State transition probabilities for 2000–2005, 2005–2010, 2010–2015, and 2015–2020 were calculated from the classified images. Simulation accuracywas 77.46%, 74.1%, 70.98%, and 78.27% for the year 2005, 2010, 2015, and 2020 respectively. Projections were made for years 2025 and 2030 and it shows a 27.41% decline from the base year by 2025 anda 29.90% decline by 2030.The amount of forest cover in the actual and simulated land-use changes shows a gradual drop from 185.15 km2 in the base year 2000 to 136.07 and 135.30 km2 in the year 2020, respectively.Spatial simulation models, which provide a scientific basis for supporting sustainable forest management based on different simulation scenarios alsocontribute significantly to the implementation framework for the United Nations' Reducing Emissions from Deforestation and Forest Degradation (REDD/REDD+) program, as well as reference scenarios for REDD/REDD+ incentive payments.

This study evaluated the immunomodulatory potential of aqueous extract of polyherbal formulation (PHF) in cyclophosphamide (CP)- induced immunosuppression in Wistar albino rats. The rats were randomly divided into six (6) groups of four (4) rats each. The normal control group received 10 ml/kg b.w of normal saline for 28 days orally. The Positive control group received 50mg/kg b.w of Levamisole Hydrochloride for 28 days orally.  Cyclophosphamide (CP) control group had 10 mg/ kg b.w of CP for three days subcutaneously.  While the Treatment control group received 1500 mg/ kg b.w of PHF orally for 28 days. Treatment 1 group received 10 mg/ kg b.w of CP for three days subcutaneously, followed by oral administration of 1500 mg/ kg b.w of PHF for 28 days.  Lastly, Treatment 2 group received 1500 mg/ kg b.w of PHF for 28 days orally, followed by subcutaneous administration of 10 mg/ kg b.w of CP for three days. On the first day prior to any intervention, 1 ml of the blood sample was collected from each rat which serve as a pre-treatment sample. At the end of the experiment (after 28 days), a blood sample was collected from each rat which serve as a post-treatment sample. The serum concentration of IFN-ã, IL-4, and IL-10 were determined using the ELISA technique. For pre-treatment samples, there was no statistically significant difference in the mean serum concentration of the cytokines across the groups (p >0.05). For post-treatment samples, there was a statistically significant difference in the mean serum concentration of IFN-ã (p < 0.0001) and IL-4 (p<0.001) across the groups. There was a significant difference when normal controls were compared with other groups in IFN-ã and IL-4 (p <0.05). No significant difference was observed in IL-10. The formulation seems to neutralise the immunosuppressive condition and induce immunostimulatory activity on the immune cells responsible for the secretion of IFN-ã and IL-4.

De Ritis described the ratio between the serum levels of liver enzymes; aspartate transaminase (AST) and alanine transaminase (ALT). The central role of the liver in metabolism makes it a necessity that it functions optimally during chemotherapeutic administration, hence the consideration of associated parameters in the management of breast cancer. This study was conducted in University of Calabar Teaching Hospital, Calabar. It included 40 cases of pathologically diagnosed breast cancer female patients who were accessing post-operative chemotherapy. Another 40 apparently healthy females drawn from the general population served as controls. Ethical approval and written informed consent were duly sought and obtained. The present study measured the levels of total and conjugated bilirubin as well as the enzyme activities for a spartate aminotransferase, alanine aminotransferase and alkaline phosphatase. Additionally, Unconjugated bilirubin derived from total and conjugated bilirubin as well as De Ritis ratio computed from aspartate aminotransferase and alanine aminotransferase were calculated. Standard colorimetric methods were used to determine the measured parameters, while derived parameters were calculated. The data obtained were analyzed in Statistical Package for Social Sciences (SPSS) using students t-test at 95% confidence level with p-value of ≤ 0.05. Apart from alanine aminotransferase that of the chemotherapy courses showed some observable effect on both derived parameters; Unconjugated Bilirubin and De Ritis ratio. The later showed a stable pattern of increment after commen cement of post-operative chemotherapy. This study indicates that routine assessment of hepatic function and De Ritis ratio should be determined as part of breast cancer management.

Service in a cultural context is needed. God set an example by entering into the context of human culture through Jesus Christ. The disciples and the Apostle Paul also preached the Gospel by adjusting themselves to the enculturation and acculturation of the local culture. This study aims to examine the attitude of the apostle Paul's enculturation and acculturation. The method used is qualitative with hermeneutic and literature studies. The research found that Paul applied God's wisdom in his outreach based on the awareness of love and awareness as a messenger of the gospel. He mingled with lowly people, felt what they felt, followed their way of life and general rules without having to taint the principles of truth that had been engraved in him. In a sense, even though Paul lived in a mingling with them, Paul did not compromise on sin. This is done so that evangelism can be done effectively.

Published: August 2022

Nowadays green buildings have become popular due to their efficiency in utilising energy and resources. While green construction is concerned, it is equally critical to establish a comfortable, healthy, and productive work environment. The classroom’s physical environment is widely known to effect academic performance and musculoskeletal discomfort. A two-part questionnaire was used to ascertain students' perceptions of the effect of the physical environment in classrooms on their reported musculoskeletal discomfort and academic performance at Cyprus International University in the green building. The results demonstrated that students' perceptions of the physical environment of the classrooms were completely appropriate for getting an education. A Kruskal-Wallis H test and a Post hoc analysis were involved in determining whether there was a relationship between demographic data and categorical variables. The results showed that age, weight, height, education level, and GPA are influenced the effect of classroom design on musculoskeletal discomfort. Likewise, height, education level, and GPA are found to be influential factors of the effect of classroom design on academic performance. The findings indicated that students' physical discomfort in the classroom is concentrated in the neck, right shoulder, upper back, and right forearm region.
Atomistic Simulation of the Effect of Temperature on Mechanical Properties of some Nano-Crystalline Metals
Authors: Igwe Isaiah Eze , Batsari Yusuf Tajuddeen
Published: August 2022

For materials with high ductility, malleability and conductivity, temperature will have significant impact on the material properties. This is especially true for pure elemental metals which have a wide range of applications due to their ultrahigh strengths. Recently, the study of damage mechanism at the nano- and micro level has attracted a significant interest and research. However, the current understanding of deformation mechanisms in nanocrystalline metals in relation to atomic structure and behavior is insufficient. In this study, atomistic simulation of uniaxial tension at nano-scale was performed at a fixed rate of loading (500 ms^-1) on some nano-crystalline face centered cubic metals (Al, Cu, and Ni), to study the nature of tensile deformation at different temperatures using the embedded-atomic method (EAM) potential function. The simulation results show a rapid increase in the stress up to a maximum value followed by a sharp drop when the nanocrystal fails by ductile dislocation. The drop in the stress-strain curves can be attributed to the rearrangement of atoms to a new or modified crystalline structure. Additional simulations were run to study the effects of temperature on the stress-strain curve of nano-crystals. The result shows that increasing temperature weakens the ductility of these nanomaterials. In this investigation, the strain corresponding to yielding stress is observed to be lower with increasing temperature. Finally, the evolution of crystalline microstructure during the entire tensile process was investigated. The atomistic simulation result of tensile deformation at nanoscale obtained in this study agree with plasticity phenomenon observed in macroscale.

Published: August 2022

Image recognition includes the categories of object localization, object identification, and image categorization. Despite
the fact that these terms are sometimes used interchangeably, object detection and object localization are not the same. Similar to
this, categorizing photographs and pinpointing their locations are two separate processes that shouldn't be mixed up. It's
important to evaluate how well these models work with data points that haven't been seen before while creating machine
learning models for use in the real world. To assess how well different models perform when applied to actual data points, we use
an assessment metric. The most popular way for gauging the success of an image localization operation is IoU. "Intersection over

Avicenna’s Šifāʾ from Safavid Iran to the Mughal Empire: On Ms. Rampur Raza Library 3476
Authors: Bertolacci Amos , Dadkhah Gholamreza
Published: August 2022

The paper aims at providing a comprehensive description of the manuscript Rampur, Rampur Raza Library 3476 (ḥikma 112), which contains three of the four main parts of Avicenna’s philosophical magnum opus, the Kitāb al-Šifāʾ  (the Book of the Cure or: of the Healing). This manuscript documents important developments in the history of Arabic-Islamic philosophy. First, it attests a precise intellectual genealogy within the influential Daštakī family from Shiraz, several exponents of which can be identified as successive owners of this manuscript at the turn of the ninth/fifteenth and tenth/sixteenth centuries, among whom one should mention Ṣadr al-Dīn Moḥammad Daštakī Šīrāzī (d. 903/1498), the founder of the so-called “Šīrāzī school” of philosophy; Ġeyās̱ al-Dīn Manṣūr Daštakī Šīrāzī (d. 948/1542), son of the preceding and author of the first extant commentary on the Ilāhiyyāt (Science of Divine Things, or Metaphysics) of the Šifāʾ in Arabic presently known; and Fatḥollāh Šīrāzī (d. 997/1589), a student and possibly also a relative of Ġeyās̱ al-Dīn Manṣūr Daštakī Šīrāzī, one of the main advocates and promoters of rationalism in India. Second, copied in 718/1318, the manuscript at hand highlights a crucial phase of the transmission of Avicenna’s Šifāʾ, at the pivotal juncture between the most ancient phase of dissemination of the work (fifth to seventh/eleventh to thirteenth centuries) and the later period of its manuscript production (ninth to fourteenth/fifteenth to twentieth centuries). Third, it offers a concrete and insightful specimen of the intellectual exchanges between the Safavid (1502–1736) and the Mughal (1530–1707) empires in the seminal and formative phase of cultural life in Iran and India in the tenth/sixteenth century, in an itinerary that from Shiraz, the place of origin of the Daštakī family, goes eastward in the direction of the Mughal court of Akbar I (r. 963–1014/1556–1605) until it reaches the Raza Library of Rampur at some point.

In this study, enhanced linearity and wide linear range current adder and subtractor circuits based on cascode current mirrors are presented. Among other analogue signal processing devices, the described circuits can be employed in operational transconductance amplifiers (OTA), Gm-C filters, and amplifiers. To enhance current mirroring performance, the suggested circuits use the cascode current mirror topology. A 1.8-volt supply and TSMC 0.18-micron CMOS technology were used to model the suggested circuits. The suggested circuits have an allowed error percentage of less than 2.5% and perform well in the current range of 0 to 80 A. The outcomes of the SPICE simulation have shown how well the proposed circuits work.

Published: August 2022

This paper provides a brief overview of the development of computer architecture and its impact on approaches to the presentation of appropriate information and computer education. The relative constancy of the concepts that were applied in the architecture of the computer influenced that the classical approaches to the appropriate education are kept until today. The changes that occurred in architecture during the development of computer technology, in conjunction with technological development, required a corresponding adjustment in the sphere of education. The turning point was the advent of the microprocessor, which introduced the x86 architecture into education. The beginning of the new century was marked by the ARM architecture. And today, the RISC-V architecture is emerging more and more as a new design challenge.

Learning temperature measurement procedures is extremely important for students of the technical professions. The previous practice was mostly based on the study of contact methods of measurement, however, due to the progress of technology, there is a need for a more detailed introduction to non-contact temperature measurement procedures, such as thermovision. When studying thermovision, in addition to the thermovision camera, the software supplied with it is also used to analyze the obtained thermograms. However, in most cases this software is not suitable for use in a teaching process. Due to this, the paper presents a solution based on the use of a different type of software compared to the traditionally used software during the introduction to thermovision procedures. The entire code for the software was developed in the Python programming language using elements of computer vision, image analysis and other capabilities that Python offers through its various modules. The entire environment intended for learning was implemented using virtualization techniques. An adequate virtual machine was implemented using free software and open source software.

A Self-Learning Object Detection Method Based on Highly Reliable Sample Mining
Authors:   College of Information Engineering, Henan University of Science and Technology, Luoyang, China., Li Di
Published: August 2022

Visual object detection is an artificial intelligence technique that locates specific objects from images, which is of great significance for practical applications. However, training general object detection models require many manually annotated images, bringing more labour and time cost. In order to improve the adaptability of the object detection model to the data environment changes, this paper proposes a self-learning object detection system based on high-reliability sample mining. We first train a SampleNet that can better mine reliable training samples from unlabeled data. We then use the combination of SampleNet and the basic object detection model to build a complementary residual training framework, continuously improving the sample mining ability and object detection tasks during the training process. The experimental results show that SampleNet can stably provide reliable pseudo samples for model training, and the complementary residual training framework improves the performance of basic object detection tasks.

Abstract

This study provides a theoretic framework for price promotions on seasonal events and popular events, such as anniversary, Christmas, and World Soccer Cup. Firms engage in collective price promotions seems to contradict economic wisdom because promotions are less likely to stand out among competitors in popular events. In a rational expectations model, this study shows all players’ performance improve in the equilibrium. Furthermore, even less-famous goods benefit from collective price promotions in which the theoretic framework can provide a guideline to manufacturers and retailers.
