Published: December 2023

In many countries, Electronic voting systems have gained significant recognition as a potential solution to enhance electoral processes' transparency, efficiency, and credibility. Elections in Nigeria have been fraught with anomalies even before the advent of the fourth republic, the 2023 general elections inclusive. This paper aims to assess the effectiveness of electronic voting systems in Nigeria by examining the challenges and opportunities associated with their implementation. Methodologically, the explanatory research design was adopted whereby a comprehensive analysis of existing literature and case studies was carried out. This study beamed light on the key issues faced in adopting electronic voting systems in Nigeria and explores their potential benefits. The findings of this research contribute to the current discourse on electoral reforms and provide insights for policymakers, electoral commissions, and stakeholders to make informed decisions regarding the future of electronic voting systems in Nigeria.

The use of large quantity of synthetic dye in process industries to colour products amongst other things has given rise to aqueous effluents containing high level of this pollutant. This paper therefore evaluates the use of isotherm, kinetic and thermodynamic to study the sorption capacities of congo red dye by mercerized sugarcane bagasse (MSB) and benzoylated sugarcane bagasse (BSB) in aqueous solution using batch experimental protocol. Data obtained show that MSB was the most effective adsorbent material, with equilibrium sorption (qe = 13.64 mg/g) after 50 minutes. The optimum pH and dosage for dye uptake were 3.0 and 3.5 g respectively. Sorption of dye by the modified surfaces decreases with increasing temperature and ionic strength. The 4% NaOH presented the best desorption of dye on the adsorbents. Kinetic studies showed pseudo second-order model fit for the experimental data. Adsorption of the anionic dye on the modified surfaces fits the Langmuir isotherm model based on the R2 values. Thermodynamic results showed ∆Go values (-12.42 to -4.16 KJ/mol) for MSB and (-15.13 to -7.55KJ/mol) for BSB, consistent with the spontaneity and feasibility of the sorption process. The uptake of dye by the modified surfaces depicts a random nature at the solid-solution interface and showed that the sorption is exothermic as evidenced by value (0.256-0.334KJmol/K) and (-18.41 to -10.17 KJ/mol) for ∆So and ∆Ho respectively. The results present MSB and BSB as effective sorbent materials for removal of anionic dye from waste effluents.

Having information about the existing stands and their structure within a forest is important, as it helps in understanding the biodiversity depth and climate change adaptation potential. Therefore, the objective of this study was to assess the growth characteristics, diversity and structure of tree species in the Opara Forest Reserve on the Nigeria-Benin Republic Fringes in Oyo State, Southwest Nigeria using appropriate standard techniques. A total of 218 trees were enumerated and assessed. The results indicated that the forest reserve is primarily characterized by the prevalence of savanna species. The dominant species within the study area consists of 80 stands of Anogeissus leiocarpus; Vitellaria paradoxa exhibits the highest mean diameter at breast height (dbh), measuring 100.09 cm and Acacia faidherbia had highest value in height. The forest reserve is characterised by the dominance of trees within the 6-10 metre height range. In conclusion, the forest reserve exhibits a moderate level of species variety with favourable growth characteristics and the average height of the trees are typical of a savanna forest.

Background: Irrational antibiotic use for childhood illnesses is prevalent, especially in developing countries. There is a need to provide evidence-based data for the implementation of antimicrobial stewardship programmes (ASP) in healthcare facilities. This study was conducted to describe the pattern and predictors of antibiotic prescriptions to paediatric patients at the outpatient clinic of Federal Medical Centre Umuahia Abia State, Southeast Nigeria.Method: We conducted a retrospective review of patients’ encounters in one year at the outpatient paediatric clinics (2022). An electronic data extraction form was used to collect information from patient’s case notes. Descriptive, bivariate and multivariate analyses were done using SPSS version 26. The level of significance was set at 5%.Results: Records of 722 encounters were retrieved. A total of 694 antibiotics were prescribed. The antibiotic prescription rate was 74.4% (95% CI: 71.2–77.6). The most frequently prescribed antibiotic was amoxicillin/clavulanic acid (34.9%). Most prescribed antibiotics (53.6%) were in the ‘access’ group of antibiotics. The commonest indication for the use of antibiotics was the treatment of respiratory infections (28.1%). The predictors of antibiotic prescription included younger age (aOR = 2.48; 95% CI: 1.50–3.80), four or more drugs prescribed (aOR = 9.43; 95% CI: 3.90 - 22.10), and therapeutic treatment type (aOR = 3.24; 95% CI: 1.10–9.40).Conclusion: Irrational prescriptions of antibiotics by physicians were prevalent in the paediatric outpatient clinic of the facility. We recommend the implementation of the ASP in the hospital to address irrational antibiotic prescriptions in line with rational drug policy.

Learning media is a means of influencing a teaching and learning process. In the absence of learning media, it is difficult for KBM to be implemented effectively. Without realizing it, learning media has an important role in addition to teachers and students as the main objects in the learning process. In this case it can be concluded that if the learning media is minimal/less then it will hinder the creation of real educational goals. Besides that, the full contribution of the school is also very much needed in creating competent teachers in order to be able to form a conducive and enjoyable student learning enthusiasm that can get encouragement in increasing student motivation in learning. The effectiveness of the assessment is also necessary in the teaching and learning process, because with the assessment the teacher can determine the abilities of each individual/student. Assessment does not only focus on the learning outcomes that have been obtained, but also on the process of how students learn. Assessment also functions as a relationship that influences each other and there is reciprocity between students and teachers, assessment in education also aims to find out the increase in student learning activities, in order to improve and enhance student learning at school and at home. Problems that often occur related to learning media usually occur in schools located in remote areas, which are far from the reach of the government. It can be exemplified by the lack of supply of textbooks and infrastructure such as projectors, etc. that can support success in learning. In this case students have difficulty finding learning resources, so the teacher must contribute to creating learning media to cover these deficiencies, because the teacher has a very big role in changing student learning.

Authors: Paredes Julieta , Gigena Rafael , Iacarino Adriana , Castro Sofía , Ibañez Carolina , Chuang Joaquín , Shinzato Sergio , Bertone Vicente Hugo , Blasi Esteban 
Published: December 2023

Introducción: Las porciones laterovertebrales sacras de las cadenas simpáticas (CSLS) se unen por un asa anastomótica anterior a la articulación sacrococcígea o a la primera vértebra coccígea. Así resulta la formación de un engrosamiento denominado Ganglio Impar (GI). Éste recibe proyecciones nociceptivas y la inervación simpática de las vísceras distales de la pelvis y periné, siendo un blanco de bloqueo nervioso ante patologías dolorosas de la región.
Objetivo: Estudiar la frecuencia de formación, morfología, localización y relaciones del GI y así brindar herramientas para poder abordar la zona con seguridad.
Materiales y método: Se utilizaron treinta y siete preparados cadavéricos de pelvis, uno de ellos seccionado de forma sagital, exclusivamente para la mostración fotográfica. Los instrumentos utilizados fueron: pinza de mano izquierda, tijeras Metzenbaum e Iris, mangos y hojas de bisturí. Por la profunda localización de las estructuras, se realizaron fotografías en 3D.
Resultados. Prevalencia y localización: la formación del GI fue encontrada en el 66,67% de los casos (24/36). De éstos, en el 50% (12/24) situándose anterior a la línea transversa entre la cuarta y quinta vértebras sacras (formación alta); y en el 50% (12/24) a nivel de la articulación sacrococcígea (formación baja). Relaciones: la CSLS se halla profunda a la lámina interureteral, a la fascia presacra y a las inserciones proximales del músculo piriforme (de anterior a posterior). En ausencia del GI, los filetes nerviosos pasan entre el vértice del cóccix y el músculo elevador del ano, tomando relación con los vasos sacros laterales. En caso de presentarse, el GI descansa sobre los vasos sacros medios, estando ambos contenidos en vainas independientes. Las relaciones difieren según la altura de formación. Morfología del GI: del total de los casos, el 29,17% presentó forma rectangular, el 12,5% triangular, y el 58,33% plexiforme. Abordajes: los abordajes fueron practicados a nivel de la línea media, siendo éstos: transsacrococcígeo, intercoccígeo y anococcígeo.
Conclusión: Concluimos que la formación del ganglio es prevalente, y la morfología predominante es la plexiforme. Cabe destacar que todos los elementos de la región presacrococcígea se encuentran detrás de la fascia presacra. El conocimiento de la anatomía y las relaciones del GI resulta de suma importancia para realizar abordajes a la misma. Consideramos que el abordaje más seguro es por la vía transsacrococcígea.
Contribución al conocimiento de los estudios geográficos en la Universidad Nacional de Cuyo.
Authors: Richard Jorba Rodolfo 
Published: December 2023

El presente trabajo es la primera parte de un proyecto que tiene por objeto analizar el nacimiento, desarrollo y afianzamiento de los estudios geográficos en la Universidad Nacional de Cuyo. Sus resultados contribuirán a un enriquecimiento de la historia de la geografía en la región y en el país.
El trabajo analiza la obra geográfica del Prof. Miguel Marzo procurando establecer las conexiones con el pensamiento que dio sustento científico a su formación.
Se revisan obras de los maestros de Marzo, estableciéndose que siguen a dos corrientes principales del pensamiento científico, y se determinan sus posibles influencias en la obra del autor estudiado. Se concluye que predomina en Marzo una concepción historicista y una inclinación hacia la escuela geográfica alemana, aunque en su obra queda en claro su independencia y pragmatismo en función de la realidad espacial argentina, diferente de la europea.

Published: December 2023

В работе приводятся результаты спектральных и фотометрических исследований звезды Ве Хербига AS 310. Фо- тометрические наблюдения показали, что амплитуда сезонных изменений блеска звезды в разные годы меняется плавным образом и достигла максимума ∆V ∼0.6 mag в 2018 г. Спектральные наблюдения звезды выявили пере- менные эмиссионные компоненты в линиях Нα и Нβ. Наши исследования показали, что AS 310 является молодой массивной звездой, которая потеряла околозвездный диск и уже вступила на Главную последовательность.
Spectral and photometric studies of the Be Herbig type star AS 310 are presented. Our photometric observations showed that the amplitude of seasonal variations in the brightness of the star varies smoothly over different years and reached a maximum of ∆V ∼ 0.6 mag in 2018. Spectral observations revealed variable emission components in the Hα and Hβ lines. Our studies have shown that AS 310 is an extremely young massive star, however, it is already on the Main Sequence.
