Systemic Racism in Canadian Higher Education: A Rapid Scoping Review of 22 Years of Literature
Authors: Cranston Jerome , Bennett Alexandria
Published: October 2024

Although the ideals of higher education promote learning and personal growth irrespective of an individual’s social identity including their perceived or declared race, systemic racism continues to subject Indigenous, Black, and otherwise racialized students, staff, and faculty to unwelcoming academic cultures and, at times, hostilities. The aim of this rapid scoping review was to identify and analyze some of the available peer-reviewed, published research literature between 2000 and 2022 focused on systemic racism in the Canadian higher education context. The authors analyzed 32 articles included in the scoping review to identify the theoretical frameworks used to situate each study. In addition, the analysis surfaced concepts related to how systemic racism is structured and enacted. Using a thematic analysis, a narrative summary is also presented to describe the experiences of Indigenous and racialized staff, students, and faculty. This study offers insight to those committed to building healthier academic communities through understandings of systemic racism as it is theoretically framed, conceptualized, and experienced.
COVID-19 Caregiving Avalanche: The Impact on Emotional Exhaustion on Female Natural Science and Engineering Academics
Authors: Vadnais Arlana , Peter Tracey , Dengate Jennifer , Farenhorst Annemieke , Mavriplis Catherine
Published: October 2024

Gender disparity persists in the personal caregiving of children and older adults, and in professional caregiving duties, with many workplace policies and cultures favoring the “ideal worker” and presenting significant and continuing barriers to female caregivers’ professional success and well-being. The recent pandemic both highlighted and augmented this disparity as schools, daycares, and adult care facilities closed or implemented restrictions. This study interprets results from the July 2021 Canadian Natural Sciences & Engineering (NSE) Faculty Workplace Climate Survey by empirically assessing the impact on emotional exhaustion of the increased caregiving burden during the COVID-19 pandemic on female academics in the highly masculinized NSE fields. Results indicate that women were more likely to experience emotional exhaustion even when other factors were considered. Collegiality and inclusion were found to be protective factors, illustrating important implications for, and the retention and support of, success and well-being of female NSE academics.

Authors: Thaivalappil Abhinand , Stringer Jillian , Young Ian , Burnett Alison , Bhattacharyya Anit , Papadopoulos Andrew
Published: October 2024

Many post-secondary institutions contain organizational values, which describe enduring beliefs that support strategic priorities and guide members of an organization. Relatedly, the adoption of health-promoting frameworks calls on embedding health within post-secondary institutions’ core values. The study objective was to map Canada’s post-secondary values to determine how health is integrated within value statements. Mixed methods were used to map institutional values, contextualize well-being, and identify thematic messages of health-related content contained within values. Most institutions espoused values (n = 64, 71%), yet only a small proportion of these institutions espoused health within their value statements (n = 7, 11%). Qualitative analysis revealed three thematic messages: (i) health as a descriptor for other institutional priorities, (ii) wellness broadly acknowledged or embedded within non-health values, and (iii) well-being as a core value or commitment. These novel findings suggest more institutions must embed health as a core value to demonstrate institutional commitment.

Published: October 2024

Nigeria’s vocational skill acquisition programme aimed to reduce the rate of unemployment. However, the programme seems to be facing some difficulties, such as poor funding by the Nigerian government, a shortage of qualified trainers for the teaching and supervision of trainees, poor monthly remuneration for the trainers, and a lack of up-to-date equipment and training infrastructure for garment-making. With the above challenges facing the programme, the research also evaluated the level of skills acquired by the trainees before becoming professional practitioners, particularly as different garment-making styles required specific techniques of sewing. This study examined one hundred and six (106) registered trainees’ competencies at the vocational skills acquisition centres through the administration of a set of questionnaires. Twenty –two (22) vocational skill acquisition centres in Ondo State offering the fashion design trade were selected for the study. The results revealed that trainees demonstrated exceptionally high proficiency in tasks such as “Trim seams” and “Replace buttons,” with over 97% rating their competency at level 5. This indicated that they performed these tasks “Very Well.” Other skills like “Stitch darts,” “Press darts,” and “Apply facings” also showed trainees’ high proficiency at performing the tasks, with the majority of them at level 5. However, some tasks revealed a small percentage of trainees’ skills at levels 2 to 4, indicating areas needing improvement.

Assessing the Effect of Leverage on the Performance of Firms in an Emerging Economy
Authors: Amoako Mr David , Domina Attafuah Dr.Edward
Published: October 2024

Leverage has been argued to be a crucial factor in determining profitability, and a number of studies have looked at its direct impact on firm performance, but the conclusions have been equivocal and contested. Using a dynamic panel model, the study attempted to contribute to the growing literature by first examining the impact of leverage on firm performance in Ghana, as well as the moderating function of firm size. The study’s data came from listed companies. The study’s sample consisted of all the companies listed on the Ghana stock exchange with particular focus on the financial firms. Dynamic panel estimation approach, specifically Arello and Bond GMM estimation technique was used for the analyses. The results show that the effect of leverage on firm performance depends on the size of the firm. For small firms, leverage has negative effect on performance. But as firms increase in size, the negative effect of increasing leverage reduces and turns positive for very large firms. The study recommended that leaders at the firm’s helms of affairs can consider diversifying their products and service in order to expand their reach and increase their size which can positively affect performance. The study finally recommends that further studies should be conducted on all firms and on all financial firms listed on the Ghana stock exchange.

Published: October 2024

Objective: To determine the pattern of blood culture isolates and antibiogram for salmonella at tertiary care hospital and identify frequency of multi-drug resistance and XDR.
Methodology: This descriptive, cross-sectional analysis was carried out on enteric fever/salmonella infected patients from 1-02-2020 to 31-10-2020 at Pediatrics Unit – II (Liaquat University Hospital). Children of either gender, aged 1 to 15 years, who presented with fever lasting more than 3 days, abdominal pain, headache, diarrhea, vomiting, or constipation, and who had a positive blood culture for Salmonella, were included. Data was collected into a structured questionnaire, containing enquiries pertaining to basic biodata, sociodemographic details, clinical presentation, and culture sensitivity (type of microbe and its drug sensitivity). The data obtained was analyzed using SPSS v. 21.0.
Results: Mean age of the children was 9.12 years, with males comprising 63.4%. Fever and abdominal pain were the most common clinical symptoms. In terms of antibiotic sensitivity, Cefixime and Ceftriaxone were effective in 83.9% and 85.7% of cases, respectively, while Ciprofloxacin showed 81.3% sensitivity. Both Meropenem and Azithromycin were 100% effective. Among the 14 multidrug-resistant cases, Ciprofloxacin had the highest resistance rate (11 cases), while Cefixime and Ceftriaxone were resistant in 9 and 8 cases, respectively. Meropenem and Azithromycin showed no resistance in any case.
Conclusion: Enteric fever remains a serious threat to child health, with rising multidrug resistance. While some drugs like Meropenem and Azithromycin are still 100% effective, they must be used carefully to prevent further resistance development.

Published: October 2024

Purpose

Cryoablation is one of the methods of treating patients with renal cancer with curative intent. This procedure is not widely available in Poland due to the lack of reimbursement until April 2023. The purpose of this study is to present the results of the first experiences in cryoablation of renal cell carcinoma in Poland.

Material and methods

Patients with renal cell carcinoma in T1a stage (up to 4 cm in diameter) were treated with percutaneous cryoablation between December 2020 and December 2023. All patients were disqualified from surgical treatment due to age, comorbidities, or history of nephrectomy. Diagnosis was confirmed by computed tomography (CT)-guided core needle biopsy that was performed 2-4 weeks before cryoablation.

Results

Twenty-five patients underwent CT-guided cryoablation of T1a renal cancer. The mean age of the patients was 77 years (43-91 years). The mean diameter of lesions was 27 mm (15-40 mm). None of the patients presented with local or distant recurrence within the mean 12-months of follow-up period (100% progression-free survival). Urine leak treated with a stent was detected in one patient. Four patients died within the follow-up period, but none of the deaths was directly related to the procedure.

Conclusions

Cryoablation is an effective and safe procedure and should be available to more patients in Poland.

Authors: Mukhanbetkaliyev E. E. , Mukhanbetkaliyeva A. A. , Аbenova А. Zh. , Berdikulov M. A. , Abdrakhmanov S. K.
Published: October 2024

Background and Aim. Epidemiologically significant objects are objects related to veterinary activities, requiring strict control and supervision, since violation of sanitary and hygienic requirements imposed on them, deterioration of the epidemiological situation at these objects can contribute to the emergence and spread of diseases, which in turn will lead to large negative economic, environmental and social consequences. This research aims to develop conventional designations of objects that have epidemiological significance in the country for their subsequent use in cartographic analysis, forecasting, and risk assessment of the spread of infectious diseases.Materials and Methods. Conventional forms were developed for almost all objects that may have any epidemiological significance. These facilities were relatively categorized into 4 areas: veterinary, agricultural, municipal, and other epidemically significant facilities. Conventional forms of designation of epidemically significant objects were developed using the CorelDraw program.
Results. In total, symbols have been developed for 48 epidemiologically significant objects, including 14 veterinary, 17 agricultural, 7 municipal, and 10 other objects. The shape of all symbols was defined as a quadrangle with equal sides, while each group of symbols has its color for the border of the figure. The design and drawing of each symbol were developed in such a way that both specialists and ordinary users could visually understand what this sign meant.Conclusion. The developed symbols will allow more effective use of information and communication technologies for forecasting and assessing the risk of spreading the most relevant contagious diseases in our country. This will subsequently allow more effective preventive and anti-epizootic measures.
Keratinolytic testing for diagnosing dermatophytosis in small domestic animals
Authors: Smagulova A. М. , Glotova T. I.
Published: October 2024

Background and Aim. Keratin is used as a structural element by numerous animal groups. Because of the strength and stability of keratin, few organisms can break it down and use it as a food source. Only a few insects, bacteria, actinomycetes, and fungi can use keratin as their sole carbon and nitrogen source. The enzymatic ability of fungi to degrade keratin has long been considered a key innovation in the evolution of animal dermatology. The aim of the work is to develop keratinolytic tests for use and to identify their pathogenicity in the diagnosis of dermatomycetes of small domestic animals.Materials and Methods. There were investigated the strains of the genera Trichophyton, Microsporum, and animal hair. The diagnosis for the detection of keratinolytic properties was carried out on three tests: hair perforation, nutrient media with grind animal hair and keratin hydrolysate. Results. The authors of this article present studies for diagnosing dermatophytosis in small domestic animals for pathogenicity using three keratinolytic tests: hair perforation, the addition of ground animal hair, and keratin hydrolysate to the culture medium. The three tests demonstrated high keratinolytic activity, which manifested as the formation of pegs on hair and the appearance of a clearing zone in the culture media under the influence of keratinase. It was also established that in media containing hair and keratin hydrolysate, the growth of cultures was faster, and the cultures did not exhibit pleomorphism, which is a positive aspect in terms of the accuracy and speed of diagnosis.Conclusion. Keratinolytic test allows to determine the pathogenicity of small domestic animal dermaticosis pathogens. The test showed that cultures do not form pleomorphisms, which contributes to the accurate identification of pathogens.

A Study on Solutions to Improve Voltage Quality and Continuous Power Supply in Distribution Power Substations
Authors: Thanh Thuy Nguyen Thi
Published: October 2024

This paper proposes some solutions to improve voltage quality and continuous power supply for electric load in distribution power substations. For the solution of using voltage tap changer in the transformer, voltage ratio can be regulated and helps to improve voltage quality for electric loads at the secondary side of the transformer. For the solution of using reserved generator, the structure of power circuit will be proposed to create another source that can replace electric power in case of having a failure at one of transformers. For the solution of using uninterruptible power supplies, their designing structure will be proposed to have many switching operations such as manual/remote/automation to limit the ability to overload and increase their lifetime. A thirteen-bus grid, called E13 grid, will be also introduce in this paper to evaluate operating parameters and the effectiveness of proposed solutions. Simulation carried out by ETAP software will show the meaning of each proposed solution to improve voltage quality for all buses in the grid and ensure continuous power supply in different operating case studies. Power losses in these case studies will be also evaluated to show the overload problem of the uninterruptible power supply in case of having different length of cable after it. Simulation results will make detailed about proposed ideas and their meaning when applied in real distribution power substations.

Published: October 2024

Food-to-food fortification is a worthwhile approach for elevating the standard of nutrition of populations. This study evaluated the quality characteristics of cookies produced from blends (%) of yellow root cassava known as provitamin A cassava (PVAC) and Bambara groundnut (BG) flours (100:0, 80:20, 60:40, 40:60, 20:80 and 0:100). The formulated cookies were evaluated for physical properties, colour parameters, anti-nutritional factors, proximate, mineral, beta-carotene, sensory properties and in vitro protein digestibility using standard methods. Moisture content of the enriched cookies (5.75-6.74%) was within permitted moisture level for cookies that will not encourage the growth of microorganisms. Increased substitution with BG flour resulted to increase in protein (3.46-16.33%), ash (2.64-4.26%), fat content (21.66-24.63%), and energy value (458.88-480.69 kcal/100g) respectively. Cookies with high beta-carotene content (47.06-91.39µg/100g) were produced as a result of incorporating PVAC flour to the composite flours. The mineral content of the cookies was shown to have decreased with increasing Bambara substitution for calcium and sodium whereas an increase with increasing Bambara substitution was recorded for magnesium, phosphorus, potassium, iron and zinc respectively. Physical properties of the cookies ranged from 8.31-9.02g weight, 4.08-4.53cm diameter, 0.54-0.68cm thickness, 6.04 – 8.46 spread ratio and 4.13-5.66kg breaking strength. Anti-nutritional factors in the cookie samples were within acceptable limits. Sensory analysis revealed that PVAC60:BG40 was the limit for moderate acceptance based on organoleptic characteristics. In-vitro protein digestibility revealed that the enriched cookies are highly digestible (76.05-81.06%) and improved with increased Bambara flour substitution. This investigation showed that the production of cookies from PVAC and BG flours gave rise to products with improved nutrient composition, digestibility, sensory properties and permissible/safe antinutrient limit which can be optimized for value addition. It is inferred that the nutrient-rich cookies made in this study would help treat vitamin A deficiency, protein energy malnutrition, and other conditions linked to poor/under nutrition.

The number of fish was 108 fish of three different species (Cyprinus carpio, Silurus triostegus, Liza abu). 66 of them were infected with Bothriocphalus achelognathi and 42 of them were not infected. The current study was conducted to know the effect of infection with the parasite Bothriocphalus achelognathi  on the chemical characteristics of fish meat such as (protein, fat, moisture) and the biochemical characteristics of blood such as (total protein, cholesterol, glucose). And blood characteristics such as (RBC, WBC, PCV) and compare them with healthy fish. The results showed a significant decrease in protein values in the muscles of infected fish, and healthy liza abu fish recorded the highest increase in muscle protein. A significant decrease (P≥0.05) was also observed in the percentage of fat in the muscles of infected fish, while there were no significant differences in the moisture percentage. As for blood biochemical tests (total protein, cholesterol, glucose). The results showed a significant decrease in the values of total protein in the blood of infected fish except for silurus triostegus fish, where there were no significant differences (P≥0.05). As for cholesterol and glucose, a significant decrease was recorded in all infected fish. The results of blood tests in the fish of the current study showed differences in blood parameters between healthy fish and those infected with the parasite Bothriocphalus achelognathi  and it was found that there was a significant increase in the number of white blood cells in all infected fish compared to healthy fish, with a significant decrease in the number of red blood cells in the fish, as well as the ratio of the measurement of the Packed cell volume.

In today’s world, adopting new technology is essential to sustain future production. Nanotechnology is becoming increasingly popular due to its efficiency in various scientific applications. In agriculture, nanomaterials significantly enhance the effectiveness of fertilizers and pesticides. Nano fertilizers, in particular, require very small quantities and leave negligible residues, making them environmentally friendly. With this in mind, an experimental trial was conducted during the winter (Rabi) season of 2023-2024 at the Department of Soil Science, HSTU, Dinajpur. The trial used a randomized complete block design (RCBD) with 7 treatments and three replications, focusing on nano-urea i.e., T1 = Control, T2 =100% RDF, T3 = Only Nano urea (3 sprays), T4 = Nano urea (3 sprays) + rest all (no urea), T5 = 50% urea + Nano urea (3 sprays) + rest all, T6 = No urea + no Nano + rest all and T7 = Only urea, respectively. The results revealed that most of the growth parameter with tuber yield was achieved highest in treatment T5, which involved 50% urea combined with nano-urea (3 sprays) and all other standard practices, followed by treatment T2 with 100% recommended doses of fertilizers (RDF). Nano-urea showed promising results in terms of dry matter percentage, chlorophyll content, % protein, and starch levels. It proved to be economically viable by reducing the use of chemical fertilizers by 50%, controlling nutrient release from the soil, providing crops with precise nutrient amounts, increasing yield, and maintaining environmental safety through improved nutrient use efficiency.

The hospital environment is a known reservoir for microbial contamination, particularly on inert surfaces, medical devices, and apparatus, posing significant health risks. This study addresses the antibacterial efficacy of four synthetic disinfectants—M.P.C. Hand Gel, M.P.C. Save Spray, Sani Wash, and Actoman Plus—against various bacterial strains isolated from Nasiriyah hospitals, including Gram-negative bacteria (Escherichia coli, Enterobacter spp., Acinetobacter spp.) and Gram-positive bacteria (Staphylococcus aureus). Despite the widespread use of disinfectants in healthcare settings, the comparative effectiveness of these specific products remains underexplored. Using standard microbiological techniques, the study evaluates the disinfectants' effectiveness against the targeted pathogens. Results indicate varying degrees of antibacterial activity, with implications for improving infection control protocols in hospital environments.

A global experiment was conducted in a private nursery for the purpose of studying the effect of fertilization and biofertilization methods on the vegetative and flowering growth of two varieties of geranium plants. Three factors were used in the experiment, such as the first factor using two varieties of geranium (the white and the red variety), the second factor represented the use of 3 concentrations of Biohealth biofertilizer (0.0, 5.00 and 10.00 mg L-1), while the third factor was the use of four types of irrigation water (tap, distill, well water and drainage water). Completely Randomized Design (C.R.D.), with three replicates for each treatment, each treatment contained three experimental units, with 3 pots for each experimental unit. Least Significant Difference (L.S.D.) was applied at the 0.05 level in data analysis. The results of the experiment showed that there were no significant differences between the two varieties on roots number and plant height, while it differed significantly in all other characteristics. Concentration was superior to all of the studied traits except for root length and plant height. Irrigation with distilled water produced a significant improvement in all characteristics except for root length, which was superior to the method of irrigation with well water.
