Water is one of the prime necessities of life for the survival of man and a host of other living things. Access to potable water supply over the years has been difficult in developing countries leading to high rates of water borne diseases, hence the need to assess the hydrogeological potential of Obada-Oko in Ewekoro Local Government Area of Ogun State. The study investigated aquifer distribution and locations of possible sites where boreholes and hand-dug wells could be drilled for potable and uncontaminated groundwater supply. The study area falls within a transition zone between sedimentary and basement complex rocks of southwestern Nigeria. Vertical Electrical Sounding (VES) and 2-Dimensional Electrical Resistivity Tomography (2D ERT) surveys were carried out using Schlumberger and Wenner arrays respectively. Resistivity data were acquired using Campus Tigre resistivity meter at twelve VES points and six 2D traverses of lengths varying from 100 to 150 m. The resistivity data obtained from 2D ERT were inverted using RES2DINV software while IPI2WIN and WinResist software were used for VES data interpretation. A maximum of five geoelectric layers namely: topsoil, clayey soil, clayey sand, sandy soil, weathered/fractured and fresh basement were delineated beneath the traverses. The weathered and fractured layers had resistivity varying from 20 to 690 Ωm and thickness varying from 12 to 27 m. The 2D ERT models showed three layers: top layer, weathered layer and fresh basement. The topsoil thickness varies from 1 to 10 m while fractured/fresh basement layer thickness vary between 6 and 13 m. The maximum depth of penetration of 2D ERT and VES were 13 m and 31 m respectively. Productive hand-dug wells/boreholes could be sited on traverses 2, 3 and 6; VES points 6 and 12 were suspected to have high groundwater potential. Though the longitudinal conductance values revealed protective capacity rating to be mostly within poor category, which made the aquifer system highly vulnerable to contamination. Physical and chemical results of analyzed water samples fell within permissible limit of World Health Organization (WHO) and Nigerian Standard for Drinking Water Quality (NSDWQ) limit for drinking purposes. Piper trilinear diagram interpretation showed calcium and chloride to be the dominant cation and anion respectively. Groundwater potential tends to be high in five locations in the study area with suitable aquiferous media for groundwater extraction.

Although herbal medicines are less potent compared to synthetic drugs in some cases, but are still considered less toxic less side effects. Cryptolepis sanguinolenta stem ethanol extract (CSSE) is a reportedly potent antimalarial plant with dearth of data on the safety and efficacy on the brain and heart of animals. This study evaluated the safety and efficacy of CSSE in animal models. Thirty albino rats were randomly distributed into five groups (n=6). Group A=distilled water (control), Groups B-E=250, 500, 1000, and 2000 mg/kg body weight extract, respectively, for 21 days. Phytochemicals and biochemical analyses were performed using standard method. Total protein (TP), direct bilirubin (DB), total bilirubin (TB), alanine transaminase (ALT), and aspartate + transaminase (AST) were evaluated in liver. Na+ -K+ -ATPase, Ca2+ -Mg2+ -ATPase, and AST were evaluated in heart. Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) and nitric oxide (NO) were evaluated in brain. Lipid profiles, malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and glutathione Stransferase (GST) were evaluated in serum as well. The results revealed that CSSE contained alkaloids, glycosides, steroids, terpenoids and proteins at 35.11, 9.80, 52.35, 22.61 and 30.32 mg/100g, respectively. CSSE significantly increased (p<0.05) liver TB and AST, heart AST, and MDA and GST, while total cholesterol and AChE was reduced. However, no significant difference (p>0.05) was observed in triglycerides, high density lipoprotein cholesterol, TP, DB, liver ALT, Na+ -K+ -ATPase, Ca2+ -Mg2+ -ATPase, BChE, NO, SOD and CAT in the subjects. CSSE also kept histo-architecture of the subjects intact. Hence, CSSE induced mild alterations in biochemical parameters and tissues of the subjects without an observable damage, hence relatively safe for consumption.

This study was conducted to determine the prevalence and level of contamination of Naira notes in circulation in Ile Ife, Osun State, Nigeria. Nine hundred and sixty (960) Naira notes comprising all denominations were collected randomly from commercial bus drivers, point of sales (POS) operators, bread sellers and open market traders between October 2023 and March 2024. The parasite egg/cysts were recovered using a standard parasitological procedure. Two hundred and thirty-seven (237) Naira notes harboured one or more parasites giving an overall prevalence of 24.7%. Ten parasites were recovered which include Ascaris lumbricoides (14.1%) Taenia spp (7.8%), Enterobius vermicularis (5.9%), Entamoeba histolytica (3.4%), Trichuris trichiura (0.6%), Ancylostoma duodenale (5.0%), Giardia lamblia (1.3%), Fasciola hepatica (1.6%), Entamoeba coli (4.7%) and Balantidium coli (0.6%). The highest prevalence of contamination was recorded in N100 notes (60.0%) followed by N200 Naira notes (26.7%) while the joint lowest contamination rate of 10% was recorded in N10 Naira and N20 Naira notes respectively. Old notes were more contaminated (29.8%) than the newly redesigned notes (4.6%) and higher parasitic contamination was recorded among paper notes (27.7%) than the polymers (18%). Mutilated Naira notes were more contaminated (85.7%) than very dirty ones (50%). Based on the source of currency, Naira notes collected from commercial drivers had the highest contamination (38.8%). Statistical associations were recorded between parasitic contamination of currency and currency denomination, currency type, source of currency note, and physical condition of Naira note (P˂0.05) except among currency materials where a nonsignificant association was recorded (P˃0.05). This study has revealed that currency notes in circulation in IleIfe, are contaminated with a variety of parasites that pose a significant risk to public health and it is essential to promote good personal hygiene practices, such as washing hands regularly, especially after using the toilet and handling currency notes.

Authors: Ahmed M.K. , Ali M.H. 
Published: January 2025

A bundle of ₦500 and ₦1000 notes were analyzed using Raman spectroscopy to simultaneously detect and localize multiple counterfeit notes mixed with genuine ones in the bundle. The research applied machine learning techniques, specifically Multiview non-negative matrix factorization (Mv-NMF) and 2D correlation analysis, to detect and assess the spectral similarity between the bundle contents and a reference genuine note, identifying individual spectra as either genuine or counterfeit. Furthermore, an approach was provided for the spatial localization of each sample bank note within a bundle, offering a detailed visualization of all banknotes in the bundle simultaneously. This research showcases the potential of Raman spectroscopy in molecular forensic analysis of a bundle for detecting and identifying the spectral signatures of multiple bank notes with a single banknote's security features, offering a viable alternative to existing individual banknote analysis and detection methods. The research may also be applicable to any security documents with a unique substrate paper that can be bundled together. Our findings offer significant benefits to financial authorities, legal institutions, and intelligence organizations around the world for the smart identification of multiple counterfeited notes.

Screening ultrasound is essential in emergency services, providing a fast and accurate tool for detecting pathologies associated with renal colic like hydronephrosis or urinary obstruction. Its portability, real-time imaging, and lack of radiation make it ideal for environments with limited resources, such as peripheral basic emergency services in Portugal, where the described case occurred.
The use of screening ultrasound by trained professionals based on theoretical and practical teaching enables an immediate response to clinical questions in emergency contexts. This article emphasizes the importance of ultrasound in the initial assessment of patients with renal colic and suspected hydronephrosis/urinary obstruction, aiding decisions regarding treatment and referral to specialists.
In this study, a patient was admitted to a basic peripheral emergency service with symptoms of renal colic. The initial ultrasound revealed discrete hydronephrosis and perirenal fluid, with bilateral patency of the urinary jets. Based on these results, conservative treatment with pain relief medication was initiated. As the patient improved, the physician decided to continue monitoring the patient with follow-up ultrasounds on an outpatient basis here, imaging improvements were observed. By the third day, perirenal fluid was no longer visible, the degree of pelvicalyceal dilation had decreased, and the patient was asymptomatic. By the seventh day, there were no signs of pelvicalyceal dilation or perirenal fluid, and the patient remained asymptomatic.
Screening ultrasound contributes to patient safety by enabling early detection of urinary pathologies and reducing the burden on central hospitals by redirecting simpler cases that can be managed on an outpatient basis with appropriate follow-up, thereby avoiding risks to the patients.

Abstract –The millennial generation is estimated to be a voter group with a very large proportion, in the city of Denpasar itself reaching 52% in the 2024 elections. This potential must be maximized by the state as an effort to increase human resources amidst the challenges of the demographic bonus in the progress of Indonesian democracy. Differences in educational background levels are the cause of social, economic and political inequality, including the accessibility of information resources. Encouraging apathy and pragmatism among youth. The lack of education about civic politics is a dilemma and the consequences are logical, where the country wants quality elections. If we look at the past few years, interest in politics among the younger generation is very minimal, this is due to a lack of socialization regarding the importance of politics for the progress of the Indonesian state. Where this will also affect the quality of human resources themselves, what is meant by this is the younger generation

Published: January 2025

Delay differential equations (DDEs) are extensively utilized in fields such as control systems, biology, and engineering to model processes where current states depend on past states, effectively accounting for time lags. Key applications include population dynamics, epidemic modeling, and economic systems, where delayed responses significantly influence system behavior. This paper presents the first extension of the Optimal Auxiliary Functions Method (OAFM) to second-order and third-order DDEs. The strength of this method lies in its convergence control parameters and auxiliary functions. Notably, the OAFM guarantees the convergence of approximate solutions after just one iteration, without requiring assumptions about small or large parameters. The method demonstrates both effectiveness and efficiency, with its accuracy validated through graphical and numerical results. Additionally, the results obtained are compared with those from the least squares method. Auxiliary functions and convergence control parameters are employed to further manage the convergence of the OAFM.
