Authors: OluGbenro Adedeji Ogundipe
Published: September 2024

Nigeria has a complicated legal and regulatory environment. This complicated history brings to mind the oft-quoted Biblical phrase, “There was no king in Israel, and every man did what was right in his own eyes.” (New King James Version Bible, 1982 Judges 17:6) As the technological landscape began to change, strong legislative frameworks are now required to guarantee the security, accessibility, and integrity of digital information. Since enacting the Nigeria Data Protection Regulation (NDPR) in 2019, and the subsequent passing into law of the Nigeria Data Protection Act (NDPA) 2023, and establishing the Nigeria Data Protection Commission (NDPC), Nigeria has reached landmark milestones in Nigeria's journey toward improving data protection and privacy. This paper provides a comprehensive analysis of the recent developments in Nigeria's data protection landscape and implications for digital records management in government agencies and businesses. This paper further tries to examine the implications of these developments for digital records management within Government Agencies and Businesses. It will also provide a brief history of digital records in Nigeria. Furthermore, it will analyze key provisions of the NDPA and the NDPC's strategic priorities and identify opportunities and challenges for aligning records management practices with the new framework. The paper also reviews the relationship between records management and organizational credibility in Nigeria, discussing how proper record management is crucial for the credibility of public institutions and organizations in Nigeria. Additionally, it attempts to show the benefit of data-driven regulatory approaches to assist organizations in navigating Nigeria's complex regulatory landscape. This paper offers recommendations for businesses, agencies, and regulators to utilize the NDPA and its strategies to enhance the adoption of digital records management. The methodology for selecting and analyzing sources involved a comprehensive literature review and policy analysis, focusing on key legal documents, academic articles, and reports from relevant agencies.

Introduction: Bryophyllum pinnatum (B. pinnatum/BP), a medicinal plant known for its diverse pharmacological properties, has been traditionally used for treating various ailments. This study investigated its potential therapeutic effects against MSG-induced oxidative stress and neurotoxicity in Wistar rats, employing both in vivo and in-silico approaches. Methods: Forty-eight adult Wistar rats (n=48) were divided into six groups: control group, MSG group, and treatment groups receiving BP extract and B.pinnatum flavonoid-rich fractions. Biochemical markers such as LDH, MDA, CAT, GST, and AChE were assessed. Neurotransmitter levels of glutamate and GABA were also measured. Molecular docking and MM GBSA analyses were conducted using Maestro 12.8v to evaluate the binding affinities of 10 B.pinnatum compounds with Nrf2 protein, NMDA receptor, and acetylcholinesterase. ADMET profiling was performed using SwissADME and ADMETlab 3.0. Results: MSG increased LDH and MDA levels significantly, while decreasing CAT, GST, and AChE levels, indicating oxidative stress and neurotoxicity. Treatment with B.pinnatum extracts and fractions mitigated these effects, restoring antioxidant enzymes/neurotransmitter levels and reducing lipid peroxidation. In silico studies showed B.pinnatum compounds exhibiting substantial binding affinities for Nrf2, NMDA receptor and acetylcholinesterase, correlating with their neuroprotective effects observed in vivo. ADMET profiling confirmed the drug-like properties of these compounds. Conclusions: B. pinnatum methanolic extract and its flavonoid-rich fraction demonstrated significant antioxidant and neuroprotective effects against MSG-induced toxicity in Wistar rats. There was significant difference in the activity levels of the flavonoid fractions as compared to the crude extract in LDH and AChE, however, the difference was only relative in MDA, CAT and GST.

This review paper of literature highlights the importance of greenhouse urban farming technology, hydroponics, aeroponics, aquaponics, vertical farming and applications of Internet of Things (IOT) technologies. The greenhouse farming is a well known modern agriculture technology for optimal plant growth. Hydroponics, a soilless cultivation technique using nutrient solutions under controlled conditions, is used for growing vegetables, high-value crops, and flowers. Vertical farming is a popular trend in hydroponics that involves stacking multiple layers of plants in a vertical arrangement. This farming method saves space, reduces water usage, and increases yields per square foot of growing area. In comparison to conventional greenhouse cultivation, hydroponics requires less fertilizer, pesticides, and water due to the precise control over their distribution. The term “Internet of Things (IOT)” is a system of interconnected computing devices, sensors, objects, microcontrollers, and cloud servers that can transmit data across a network and control other devices remotely without human intervention. A better management of nutrient solution in hydroponic systems requires optimum pH, electrical conductivity (EC), or ions concentration. The three main greenhouse farming gases (GHGs) emissions in hydroponics hi-tech urban farming are nitrous oxide, methane and carbon dioxide (CO2). To measure the levels of CO2 in hydroponics, the more intermediate to advanced grower can use a CO2 monitoring and controllers system. Hydroponic vertical farming is in infancy in India. Although hydroponic vertical farming units for production of crops like strawberry, lettuce and other leafy vegetables, foliage and flowers are functioning in major metros of India. However, the organized hydroponic vertical farms for production of food crops are not available in India. Therefore, only a few successful hydroponic vertical farms have been built in India mainly due to the initial high price tag on construction and the cost of maintaining them afterwards. Another disadvantage is carbon footprint of hydroponic vertical farming is very high, and discourages its applications.

Published: September 2024

Garfish is a small pelagic species that has long been used as a raw material for dry fish production from Maluku called balobo dried fish. Many species of Garfish have been exploited but the species Hyporhamphus quoyi has not much been informed. This study aims to understand the reproductive aspects of Garfish consisting of measuring the sex ratio, changes in the gonad maturity stages (GMS) and counting the size of the first size gonad maturity. Located at the waters of Apara village, Aru Archipelago Regency, this study was conducted using a balobo net from November to December 2023. The catches were identified, measured its fork length (FL cm) and dissected to examine its reproductive organ.  The Chi-squire heterogeneity test was occupied to measure sex ratio at different sizes. GMS was accessed based on the morphology of testis and ovary. First size maturity was calculated using Spearman-Karber method. The target fish captured by the balobo net consists of the Hemirhamphus far and Hyporhamphus quoyi. The ratio of male and female Hyporhamphus quoyi is unbalanced (c2=8.36; df=1; P=0.0038) but the sex ratio based on the length distribution of fish is not significantly different ( c2=6.92; df=6; P =0.328). Changes in GMS during the observation period indicate the occurrence of spawning in November. Balobo fish reach gonad maturity at FL = 24.9cm for females and FL = 26.8cm for males. Since the optimum size of the fish Hyporhamphus quoyi caught by balobo net is 27cm, this net produced legal sized of fishes.

Solving One-Dimensional Non-Linear Klein-Gordon Equations via Combining Adomian Polynomials and Rohit Transform Method
Authors: Gupta Rohit , Gupta Rahul
Published: September 2024

In this study, one-dimensional non-linear Klein-Gordon equations are solved by applying the integral transform known as the Rohit transform method. The approximate solutions of one-dimensional non-linear Klein- Gordon equations are obtained by combining the Adomian polynomials with the Rohit transform. To show the effectiveness and performance of the Rohit transform method, five one-dimensional non-linear Klein- Gordon type equations are considered and solved. The graphs of the solutions obtained are plotted to indicate the generality and clarity of the proposed method. It can be easily verified that the proposed method yielded the results that satisfy their corresponding non-linear Klein-Gordon equations. The integral Rohit transform combined with Adomian polynomials brought progressive methodologies that offer new insights on the problems (i.e., one-dimensional non-linear Klein-Gordon) examined in the paper, distinguishing itself from existing methods and doubtlessly beginning up new research instructions. Moreover, it reduces the complexity that occurs when non-linear Klein-Gordon are solved by other methods available in the literature. It provided precise results for the specific problems discussed in the paper, surpassing the capabilities of different methods in terms of decision, constancy, or robustness to noise and disturbances.

Authors: K. H. Moussa Yusra , Alwehab Abdelwehab A.
Published: September 2024

The expansion of building blocks at the expense of agricultural land is one of the main problems causing climate change within the urban area of a city. The research came to determine these indicators, as a study was conducted on the expansion of the building blocks in three municipalities in the city of Baghdad for a period of four decades extended in the form of time cycles for the period (1981-2021) and using ArcMap GIS 10.7 technology. Then, the impact of this expansion on temperature rates was evaluated, as they are the most important climatic elements due to their significant effect on the rest of the elements. The results showed a clear, direct relationship between the increase in urban expansion rates and the corresponding rise in temperature rates, which results in urban heat islands. The results for the last time cycle showed high expansion rates for the municipalities of Al-Kadhimiya, Al-Shaala, and New Baghdad (62.2, 82.4, and 92.1), respectively, and were offset by high-temperature rates (25.2, 25.49, and 25.67) for the same municipalities, respectively, as the highest rates were recorded in the New Baghdad municipality, followed by the municipality of Al-Shaala, in second place, then the municipality of Al-Kadhimiya, with the lowest rates due to its location on the Tigris River.

Published: September 2024

Theoretically, the AlxGa1-xAs/GaAs superlattice is studied as a function of optical energy with and without bias. The transfer matrix approach has determined the transmission coefficient and resonant tunnelling current density. The number of barriers is estimated at N = 3, and the concentration ratio (the mole fraction value) x at 0.1, 0.2, and 0.3 is fixed. The number of cells in the well is established at (ncw) = 5, while the number of barrier cells (ncb) is changed from 1 to 5 for both biases. This study shows that the change in the number of barrier cells plays a crucial role in the tunnelling of charge carriers and the transmission probability of charge carriers through the depletion regions. Thus, changing the current density is based on the purpose to be applied. In addition, the values ​​of current density at the reverse bias are higher than that in the forward bias, which is explained by the bias controlling the energy levels of the superlattice. It is worth noting that there are many practical applications in which this system can be used, including solar cells, detectors, and light-emitting diodes.
Synthesis of PPy-MnO2 Nanocomposite for Utilization in Supercapacitor Applications
Authors: Hameed Firas J. , Ibrahim Isam M.
Published: September 2024

Polypyrrole (PPy) nanocomposites were prepared using chemical oxidation and were combined with manganese oxide (MnO2) nanoparticles. The PPY-MnO2 nanocomposite was synthesized by integrating PPy nanofibers with varying volume ratio percentages of MnO2 dopant (10, 30, and 50% vol. ratio). The structural features of the PPy and PPy-MnO2 nanocomposite were investigated using X-ray diffraction (XRD).  Fourier transfor infrared (FTIR) spectroscopy was used to demonstrate the molecular structures of primary materials and the final product of PPy, MnO2, and PPy- MnO2 nanocomposites. Field Emission Scanning Electron Microscopy (FESEM) showed that the morphology of PPy consisted of a network of nanofibers. Increasing the volume ratios of manganese oxide added to the PPY nanofiber led to the increase of manganese oxide nanoparticles on the surface of the PPY nanofiber network. This resulted in a noticeable alteration in the structure of the nanocomposite. It has been observed that the nanocomposites demonstrate a significant level of pseudocapacitive activity.  The highest capacitance of 236 F/g was observed when pure PPy was doped with 30% MnO2 compared to 125 F/g of the pure PPy.
Physical Properties Studies of Magnesium Phthalocyanine (MgPc) Thin Films of Different Annealing Temperatures Prepared by Pulsed Laser Deposition Technique
Authors: G. Adnan Noora , K. Hassan Eman
Published: September 2024

Magnesium Phthalocyanine (MgPc) was deposited on a glass substrate by pulsed laser deposition (PLD) using Q-Switching Nd:YAG laser with wavelength 1064 nm, repetition rate 6 Hz, at room temperature (300K) and different annealing temperatures (373, 473, and 573)K under vacuum condition of 10-3 torr. All films were annealed for one hour to attain crystallinity. X-ray diffraction (XRD) of MgPc powder indicated that MgPc crystallizes in polycrystalline with a monoclinic structure. While comparing the MgPc films, it was observed that the intensity of the characteristic peak increases with temperature, and the crystallization exhibited a monoclinic structure typical of the β-form. The Miller indices, hkl, values for each diffraction peak in the XRD spectrum were calculated. The characteristic peak of Phthalocyanine (MgPc) was found at 2θ value 6.9137ᵒ with the hkl value of (100) for both MgPc powder and deposited thin films. Field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray spectroscopy (EDX) analyses indicated that crystallinity improved and surface morphology was enhanced with the rise in annealing temperature and showed uniform-sized grains. They also assisted in identifying the optimal parameters that yielded the best structural properties for the film. The optical properties of MgPc thin film showed two absorption bands. The MgPc thin films exhibit transport and onset direct energy gaps (Eg) for all samples. Additionally, the absorption coefficient (α) was calculated using Lambert Law, revealing a slight dependence on the annealing temperature.

Authors: Abdulameer Maha .F. , Khalaf Thamer H.
Published: September 2024

In this research, the dynamics of double-head streamer discharge initiation, propagation, interaction and breakdown in the air under different pressure values were presented. The double-head streamer discharge dynamics were analysed within a plane-to-plane electrode configuration. That was done through many aspects proposed, such as electron density, electric field, space charge density and streamer propagation speed. The simulation performed using ‘COMSOL Multiphysics’ is based on the finite element method and was carried out with the fluid model. The fluid model describes the movement of particle concentrations using partial differential equations (PDEs) together with Poisson’s equation; Poisson's equation and charge concentrations determine the electric field distribution in space. According to the results, as the pressure increased from (1, 2 and 3atm), the evolution time of the streamer increased from (0.563 to16.29ns) with the same breakdown voltage of 19kV. This means that the double-head streamer discharge developed faster with the decrease in pressure.

We conducted a study to determine the most effective method of preserving lentil seeds for future sowing. The experiment involved six different types of storage containers: cotton cloth bags, tin containers, earthen pots, plastic containers, polythene bags, and gunny bags. We also used four plant extracts: Piper betel (Betel leaf), Azadirachta indica (Neem), Allium indica (Garlic), and Swietenia mahagoni (Mahagani). We measured the vigor index and germination percentage at 2, 4, and 6 months after storage, and then documented the fungal connection. In a separate experiment, we conducted a pre-sowing seed treatment using botanicals and biological agents such as garlic (5% w/v aqueous solution), datura (5% w/v aqueous solution), mehogoni leaf extract (5% w/v aqueous solution), mehogoni seed extract (5% w/v aqueous solution), and fern leaf extract (5% w/v aqueous solution). We treated the seeds with various substances to suppress seed-borne fungi, including ash coating (10 g kg-1 seed), fresh cow dung coating, a solution of cow urine (5% v/v water), Provax-200 (2 g kg-1 seed), and an untreated control group. In terms of germination, vigor index, and seed infection, the lentil seeds stored in a polythene bag with neem leaf extract significantly outperformed the other treatments. We found that the durability of lentil seeds significantly decreased as the storage time increased. The seed treatment fungicide Provax-200 had a significant impact on lowering the presence of fungus (by 87.41%) and boosting the germination percentage (by 39.49%) of lentil seeds.

Beverages are an important part of the food sector their storage is also one of the most critical issues. This study investigated the effects of different storage temperatures and times on physicochemical properties, flavonoid and organic acid contents of soda, sherbet and ice tea produced by adding sour grape concentrate. Changes in the flavan-3-ol content of ice tea were also measured during the storage period. The beverages were stored in three different conditions, cold storage (~4°C), room temperature (~24°C) and controlled storage (20±1°C), for six months and analyzed every two months. Storage temperatures and time affected the total soluble solids and acidities of the beverages (p≤0.05). Tartaric acid decreased during storage, especially during the first two months in sherbets. Ice tea and soda drinks were found more stable than sherbets. The malic acid was found the major organic acid in beverages. Flavonoid content in ice tea was higher than others. The flavonoid concentrations of ice tea stored at 20 and 24°C and of sherbet at 4°C were statistically significant as a function of storage time while these values were not significant for ice tea stored at 4°C and of sherbet at 20 and 24°C (p≤0.05). Concentrations of flavan-3-ols varied with storage conditions. The levels of epicatechin, epigallocatechin and epigallocatechin gallate in ice tea samples decreased between an average of 43.72 and 71.15% at the end of six months of storage. Principal component analysis separated two months storage from other storage periods and perfectly discriminated the studied flavan-3-ols except catechin. Soluble solid and brix-acid ratio also dissociated similarly to flavan-3-ols.

The purpose of this research presents the research results obtained from a numerical simulation using the ABAQUS/CAE version 2019 finite element software. This study tested the shear behavior of T-beams made of reinforced concrete (RC). The structure is reinforced with a carbon fiber reinforced polymer (CFRP) bar embedded through a section (ETS). The numerical validation approach implicated using numerical analysis on the experimental data collected from twelve reinforced concrete (RC) T-beams divide into two groups each group include reference beam, the field of numerical analysis was expanded to encompass the examination of many aspects, such as the impact of the diameter of CFRP bars. The main objective of this project is to create a computational model that accurately transcribes the complex nonlinear properties inherent in beams. This work conducts a comparative investigation of computational and experimental models, with a specific focus on their load-deflection features and cracking patterns. The study found that the average ratio of ultimate load to deflections in numerical model simulations for beams was 1.011, whereas in experimental testing it was 0.928. The research findings establish a clear correlation between the diameter of CFRP bars and the stiffness of a beam, assuming a constant angle of inclination and spacing.

This study investigated how family socioeconomic status (SES), parenting stress, and home learning environment collectively shape children’s early academic learning concurrently and longitudinally. Drawing on the family investment model and the family stress model, we tested mediational models in which family SES predicted children’s early academic skills through parenting stress and home learning environment. Participants were 130 Hong-Kong-Chinese toddlers (76 girls; Mage = 33.09 months). Children’s early language, literacy, and math skills were measured at two timepoints six months apart. Parents reported families’ demographic information, parenting stress, and home learning environment at Time 1. Cross-sectional findings showed that family SES positively predicted children’s concurrent language and math skills through the mediation of home learning environment. Parenting stress negatively predicted children’s concurrent language, literacy, and math abilities through the mediation of home learning environment. Moreover, longitudinal findings indicated that home learning environment mediated the relationship between parenting stress and children’s math skills six months later after controlling for children’s prior level of math skills. However, the chained mediation paths involving both parenting stress and home learning environment as mediators serially between family SES and child outcomes were not significant. This study demonstrates the interwoven effects between family factors on promoting children’s early learning, highlighting the pivotal role of the home learning environment in multiple mediating processes.
Hybrid Block Chaotic Compressive Sensing and Chaotic Scrambling Algorithms for Color Image Encryption System
Authors: H. Sahar Asaad , A. Hussein Al-Delfi Hussein , F. Hassoon Ali
Published: September 2024

This paper suggests a new image encryption algorithm based on block compressive sensing (BCS) and chaotic scrambling techniques. With compressive sensing (CS), signals can be sampled much lower than the Nyquist-Shannon rate while preserving their information content.  BCS can be used as a one-step process by using a 3D logistic chaotic map, the measurement matrix is used as a secret key for encryption.  BCS algorithm used an individual image reconstruction algorithm that leverages l_1norm minimization to promote signal sparsity, and a smoothing operator to enhance image quality. An encrypted image is first decomposed into three sub-images based on the tricolor theory; then, a discrete wavelet transform is used to sparsely process the three decomposed images. A 2D Henon map is used to scramble the compressed image after compression. This process further enhances the security of the system by increasing the complexity of the encryption process. The results showed that the proposed system provides better security and has a lower computational complexity than other methods. Furthermore, the proposed system is resistant to known attacks such as brute force and statistical attacks.
