Published: January 2024

This paper aims to investigate the mechanical and metallurgical properties of magnesium AZ91 composite. Zinc and Aluminium were selected as reinforcement particles in the Magnesium metal matrix composite. The composites 88.5%Mg-9%Al-1.5%Mn-1%Zn, 87.5%Mg-9%Al-2.5%Mn-1%Zn, 86.5%Mg-9%Al-3.5%Mn- 1%Zn, 85.5Mg-9%Al-4.5%Mn-1%Zn, 84.5%Mg-9%Al-5.5%Mn-1%Zn and 83.5%Mg-9%Al-6.5%Mn-1%Zn are prepared through powder metallurgy. The hardness and compressive tests are used to investigate the mechanical properties of the magnesium composite. The results of the mechanical properties indicate that manganese plays a vital role in improving the hardness of the AZ91 composite. The thermogravimetric analysis investigated the weight ratio % at the 400OC. The scanning electron. microscopic analysis was used to investigate the reinforcement particle's bonding level and the defects on the composite. Based on the results, the manganese plays a vital role in improving the mechanical properties of the AZ91 composite.

Published: January 2024

Production of fuels and chemicals from renewable biomass is crucial to sustainability of bio-based economy. In this study, anaerobic digestion of corn stover (CS) was carried out to produce biogas under mesophilic conditions. The study also investigated the potential of corn stover digestate ash as a potential source for biosilica production. A cumulative volume of 930 mL of biogas was produced with methane content of 85.87%. Higher and lower calorific values of biogas were calculated to be 36.30 MJ/m3 and 32.70 MJ/m3, respectively. Calcination of raw CS (RCS) and the digestate (CSD) was carried out at 600 °C for 3 hours. The samples generated, raw corn stover ash (RCSA) and corn stover digestate ash (CSDA) were characterized using X‐ray fluorescence (XRF), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscope (SEM), and X‐ray diffractometer (XRD). The XRF results revealed that CSDA biosilica content was 60.49%, which was 34.84% higher than RCSA. There was reduction in most of the metallic impurities in CSDA compared to RCSA. Potassium oxide was drastically reduced from 12.34% to 1.60%, while Al2O3 was reduced from 7.17% to 6.95%. SEM images showed the changes in the surface morphology of RCSA and CSDA, while FTIR spectra identified the changes in the key functional groups present in the samples. The study showed that CS and its digestate could serve as profitable renewable feedstocks for bioenergy production and bio-based chemicals like silica.

Published: January 2024

Possession of virulence factors such as extended spectrum beta lactamase (ESBL) by pathogens generally exacerbates morbidity as well as increases healthcare costs. This study determined the production of ESBL among Escherichia coli isolated from the urinary tracts of subjects attending General Hospital, Minna, Nigeria. One hundred and fifty (150) urine samples were collected from subjects and cultured on CLED agar for the isolation of E. coli. Antibiotic susceptibility testing was done using Kirby Bauer disk diffusion method, while the phenotypic identification of ESBL-producing strains was carried out using double disk synergy test. All results were interpreted based on Clinical and Laboratory Standards Institute guidelines. In all, 26 (17.33%) out of the 150 urine samples cultured had E. coli; out of which 23 (88.5%) were subsequently found to be ESBL producers. Among the E. coli isolates, high rates of antibiotic-resistance was observed against nalidixic acid (100%), cefdinir (88.4%), cefotaxime (84.6%) and cefpodoxime (84.6%), while remarkable sensitivity to tarivid (46.1%), ciprofloxacin (38.4%) and gentamicin (34.6%) was also detected. This study has established the involvement of ESBL-producing E. coli in urinary tract infections in the study area. Rational prescription of antibiotics against pathogens generally is highly recommended to halt the spread of resistance.

Published: January 2024

Anti-diabetic activity of aqueous extract of Chrysophyllum albidum stem bark (AECASB) in female Wistar rats was investigated to confirm or refute the purported use and the underlying mechanism of action of C. albidum stem bark in the management of type 1 diabetes in Nigeria traditional medicine. Seventy female rats (180.60 ± 8.50 g) were assigned into seven groups. Rats in Group 1 (non-diabetic) were orally administered 1 mL of distilled water, while animals in Groups 2-7 were made diabetic and orally administered 1 mL of distilled water, 2.5 mg/kg body weight (bwt) of glibenclamide, 25, 50, 100 and 200 mg/kg bwt of AECASB, once daily for 14 days, respectively. Fasting blood glucose (FBG) levels of the rats were determined on days 0, 1, 4, 7, 10 and 14. Other biochemical, hematological parameters and pancreas histology of the rats were also determined/examined. The 25 mg/kg bwt of AECASB produced the most significant (p < 0.05) reversal on the alloxan treatment-induced increases in FBG, biochemical and hematological parameters and regenerated the pancreas. In conclusion, the 25 mg/kg bwt of aqueous extract of C. albidum stem was the effective in the management of diabetes and might have acted via regeneration of the pancreas, enhancement of glucose utilization and reduction of blood glucose.

Introduction Pakistan possesses a larger stone burden in paediatric patients. In the paediatric population, proper and timely diagnosis of renal stones to get the best stone-free rates is essential. This study aims to assess CT-KUB as a diagnostic tool for renal stones in the paediatric population before PCNL. Methodology This is a retrospective, cross-sectional study. Patients between 1 – 15 years with a diagnosis of renal stones were included in the study. Radiological investigations including Ultrasound KUB, X-ray KUB, and before the procedure, CT-KUB were documented. Pre-operative, per-operative, and postoperative complications are used to assess the success of the procedure. The statistical package of Social Sciences 22 was used to enter, sort, and analyze the data. Variables were analyzed in mean ± standard deviation and frequency and percentages. The chi-square test was used to assess the significance of mean differences keeping the p-value as ≤ 0.05. Results The mean age was 4.7 ± 3.8 years with a range of 1 -14 years. After the procedure, 104 (86.6%) were rendered stone-free after the first setting. Only 1 (0.8%) was converted to an open case (Pyelolithotomy). The mean stone size encountered was 1.3 ± 0.7 cm in greatest dimension as measured on the CT scan. Postoperatively, there was a hemoglobin drop of 2.3 ± 0.5 g/dl noted, mean operative time was 94.8 ± 17.4 minutes. Conclusion CT KUB proves to be an important and accurate preoperative diagnostic tool in assessing patients with renal stones in the paediatric population.

ПЛАСТИЧЕСКИЕ ТРЕНИНГИ ДЛЯ ПРОФЕССИОНАЛЬНЫХ АКТЕРОВ В ТЕАТРАХ КАЗАХСТАНА
Authors: Ембергенова Альфия 
Published: January 2024

Профессиональное дополнительное образование важно в любой сфере. Оно помогает профессионально расти, быть в курсе актуальных трендов, тем самым развивать компанию. К сожалению, в Казахстанском театральном искусстве не проводятся лаборатории, резиденции, школы для действующих актеров, как это принято в зарубежных странах. Только маленькая доля театров проводит образовательные мероприятия для своих артистов, приглашая мастеров из других городов и стран.
Современное театральное искусство ставит новые задачи перед режиссёрами, актерами и театрами в целом. Спектакли приобретают визуальный, экспериментальный, перформативный формат. Пластическое решение сцен стало широко применяемым решением режиссёров в Казахстане. Однако профессиональная подготовка актеров не всегда может соответствовать ожиданиям режиссёра, что сказывается на итоговом результате.
Данное исследование основано на личном опыте автора, который проводил тренинги по пластике для профессиональных актеров. В основу статьи легли результаты тренингов, проведенных в разные годы в период с 2016 года по 2022 год в Казахском Государственном Академическом театре для детей и юношества имени Г. Мусрепова, Туркестанском музыкально-драматическом театре, Корейском Государственном театре, Кызылординском музыкально-драматическом театре им. Н. Бекежанова. Программу тренингов составил опыт автора, полученный за время обучения и стажировок в Dell’Arte International School of Physical theatre в США, Paris Summer Academy во Франции, Janacek Academy of Music and Performing arts (JAMU)в Чешской Республике, Gecko physical theatre company в Великобритании, проектах СТД РФ в России. Статья является теоретическим осмыслением практического опыта. Автор поднимает вопрос важности дополнительного послевузовского образования для профессиональных актёров.
PAPEL DE LA CONTABILIDAD Y LA AUDITORÍA FORENSE EN EL SISTEMA PENAL ACUSATORIO EN LA REPÚBLICA DE PANAMÁ
Authors: Burton Mauricio , Concepción Sosa Marta 
Published: January 2024

El Sistema Penal Acusatorio que rige en Panamá desde septiembre de 2011 trajo nuevos retos para los profesionales de la Contabilidad, muy en especial para aquellos que se dedican a la auditoría forense y al peritaje contable, siendo uno de esos retos la modalidad de la oralidad que rige el Sistema Penal Acusatorio. La Contabilidad siempre ha sido un elemento importante para la justicia puesto que por medio de los informes presentados permite a la fiscalía tener elementos que le ayuden en sus investigaciones y por medio de la intervención oral realizada por los profesionales contables permite a los jueces aclarar conceptos para determinar la culpabilidad o no de un acusado. Por lo antes expuesto es importante que el auditor o contador conozca la importancia de su rol en el Sistema Penal Acusatorio con el objetivo de mejorar su desempeño y aportar con su trabajo a la justicia.
Creación de un Modelo Matemático para Perfeccionar la Dinámica de los Barcos, en la Industria Naval, en el 2023
Authors: Villarreal Cisneros Jorge Antonio 
Published: January 2024

La dinámica que presenta los barcos se perfeccionó, por medio de la mecánica analítica, el cual determina la naturaleza real de los navíos. El objetivo de este proyecto de investigación es construir un modelo de barco mediante las ecuaciones de Euler-Lagrange y no por el método clásico de Newton. La importancia de construir un modelo de barco basado en estas ecuaciones, es que permite tener un barco más resistente a las perturbaciones.
La intención de proponer este modelo matemático permitirá entender, no solo la mecánica del barco, sino también establecer su eficiencia. La metodología empleada es de enfoque cuantitativo, con un nivel de investigación aplicativo, debido a que se construyó un modelo matemático del barco basado en el principio de mínima acción de Hamilton para obtener las ecuaciones de movimiento. Además, se empleó el software Matlab para simula la cinemática y dinámica del barco diseñado a partir del modelo matemático empleado. El resultado que se obtuvo demuestra que el modelo matemático utilizado es adecuado para comprender la cinemática y dinámica de los barcos.
Understanding Accreditation Requirement Trends of Teaching Occupation in Occupational Therapy Curricula
Authors: Mernar Thomas J. , Herzberger Leighan 
Published: January 2024

Abstract
Accreditation standards covering occupation have evolved across recent versions of the Accreditation Council for Occupational Therapy Education’s (ACOTE®’s) academic B content standards. Because occupational therapy and occupational therapy assistant academic programs are required to provide evidence of compliance with each B content standard, the level of students’ learning of occupation warrants attention. The revised Bloom’s taxonomy offers a useful framework for examining hierarchical learning action verbs that underpin the degree of complexity of students’ learning of occupation within the ACOTE standards. In this column, we provide an analysis of action verbs across ACOTE standards from 2006 to the most recent, 2018 version. The findings reveal a reduction in accreditation requirement trends covering occupation in both lower and higher order cognitive skill levels as described in the revised Bloom’s taxonomy. We advocate for increased curricular content centered on the foundations of occupation so that students and future practitioners can increasingly apply, analyze, evaluate, and creatively use occupation in the classroom and in practice.
Studying the Specificity of Research Reporting for Ayres Sensory Integration® Interventions in the Published Literature: A Scoping Review
Authors: Choudhury Ishanie , Tarver Talicia , Davis Mary , Reynolds Stacey 
Published: January 2024

AbstractImportance: A contributing factor to the gap between research publication and clinical implementation is the lack of specificity used when reporting findings.Objective: This scoping review used the Rehabilitation Treatment Specification System (RTSS) to determine which elements of specificity are most often present and omitted from research using Ayres Sensory Integration® (ASI).Data Sources: The following databases were searched: PubMed, CINAHL, PsycINFO, Cochrane Library, and ERIC.Study Selection and Data Collection: Eligible studies used ASI in an outpatient setting with children who had sensory integration or processing difficulties. Studies selected were quantitative (Level 1, 2, 3, or 4), available in full text, peer reviewed, and published in English within the past 20 yr.Findings: Of the 22 studies that met inclusion criteria, 100% included ingredients (actions of the therapist), 63% included mechanisms of action (reasoning behind these actions), 86% included targets, and 23% described client progression. We also found that 49% of all ingredients were listed in conjunction with a target, 15% were listed in conjunction with a mechanism of action, and 11% were listed in conjunction with both a target and a mechanism of action.Conclusions and Relevance: Findings indicate that many studies list ingredients but often omit the mechanism of action. This omission makes replication of the intervention increasingly difficult and prevents a deeper understanding of the clinical reasoning process behind the intervention.Plain-Language Summary: Gaps identified in this scoping review highlight inconsistencies in the reporting of treatment specificity that may affect the replication and translation of Ayres Sensory Integration® (ASI) research into practice.
