From The Gongola to The Forcados: Colonial Water Transport and Economic Development In Nigeria
Authors: Bello Muhammad A. , Ya’u Usman Isah
Published: January 2025

In the course of European imperial expansion, movement was done through rivers to penetrate the interior of Africa and establish colonial rule, thereby promoting commercial and industrial development at the expense of Africans. Following the British imperial penetration of the Nigerian area and the military conquest of its peoples, they utilized navigable rivers from the South to the North in the transportation of goods and services to a number of port-towns for redistribution and consumption in the hinterland. European manufactured goods were brought to the Nigerian coastal areas, including Burutu, one of the major ports through which goods were imported and evacuated by cargo ships. Through Burutu port on the Forcados River in the Niger Delta, large quantities of imported goods were transported by ships to Lokoja on the Niger River, Makurdi and Numan on the Benue River, to Nafada and Dadin Kowa ports on the Gongola River. At the same time, large tons of agricultural and forest products were exported through the same waterway. This paper, which is based largely on the use of archival records, examines the process of the utilization of the Gongola River flood waters in Northern Nigeria in the colonial water transportation of goods and services to the Forcados River in Southern Nigeria, thereby facilitating the process of the economic development of the country.

Authors: Najat Mohammed  , Tahani Mohammed  , Nisreen Farag
Published: January 2025

Chronic kidney disease (CKD) is a serious health problem that can lead to end-stage renal disease. Patients with CKD are usually suffered from anemia, which is one of the major consequences of kidney damage which in turn lead to reduce quality of life, increased risk of cardiovascular disease and cognitive impairment. The study aimed to assess the hematological abnormalities in the CKD patients during pre-dialyzed conditions in EL-Beyda City. The study was included 107 patients who are attended to Nephrology Department in EL-Bayda Medical Center in the period from November 2021 to March 2022. The study was included all CKD stages and were not on dialysis and they were following upped by these centers regularly each month. Data sources were obtained from the personal interview with patients and the records files in Nephrology units. Blood samples were taken in EDTA tube to measure complete blood counts (CBC) include hemoglobin (Hb), hematocrit (HCT), Mean cell volume (MCV), Mean cell hemoglobin (MCH), Mean cell hemoglobin concentration (MCHC), white blood cells (WBC) and platelets count (PLT), as well as renal function tests (blood urea and creatinine). The data were analyzed by Minitab version17. Out of 107 patients were included in this study, 63(58.8%) of patients were females and 44(41.1%) were males, The majority of patients had chronic diseases which could be the contributing cause of CKD; 62% were suffered from hypertension, 40% suffered from diabetes. Anemia was the main abnormality in our study which observed in 49 of participants (45.8%) while the others were non anemic accounting 54% (14.6±0.23). There was a significant difference in the mean of hemoglobin and hematocrit between anemic and non-anemic participants (p- value=0.000). Red cell indices showed normocytic normochromic anemia, thrombocytopenia was noticed in 7 (14%) of patients and leukocytosis was reported in 9 (18%) of them. We can conclude that developing of anemia in CKD patients is associated with poor outcomes and requires a careful management to avoid comorbidities.

The article provides an overview of anthropogenic factors negatively affecting the geosystems
of the Ilek River basin. The accumulation of chemical elements and their introduction
into the environment result from human industrial and agricultural activities. The article
examines natural and anthropogenic causes that adversely impact the qualitative composition
of surface waters in the Ilek River basin. It also considers the hydrological regime of
the Ilek River and its major tributaries based on field observations conducted in 2024.
The study identifies natural and anthropogenic factors that have been influencing the geosystems
of the Ilek River basin for decades. Results of chemical analyses of surface water samples from
key sites demonstrate a clear correlation with elements of the technosphere. It has been established
that first- and second-order tributaries of the Ilek River, located in the northeastern part of the
basin, are polluted with heavy metals due to mining and geological exploration activities.
The Water Pollution Index (WPI) was calculated for the Ilek River and its major tributaries.
The findings indicate that while the water bodies of Aktobe oblast, which remain underresearched, generally meet surface water quality standards, the surface waters in the middle
reaches of the Ilek River are classified as highly polluted. This highlights the necessity for
more comprehensive investigations to prevent further deterioration and to develop measures
for reducing pollution levels.

According to world research, over the past decades there has been a tendency for air temperature
to rise and an increase in the frequency of extreme weather events. The study of the climatic
predisposition of individual regions to extreme events, in particular fires, is an urgent problem
of our time. The main purpose of this study was to define current trends in air temperature in
Eastern Kazakhstan on an annual, seasonal and monthly scale. The non-parametric Mann-Kendall test and Sen’s slope estimation were used for the analysis, and the co-kriging method
was used to interpolate the data to obtain areal distribution. As a result of the study, it was
revealed that in most of Eastern Kazakhstan, there has been an increasing trend in average and
maximum temperatures significantly. It was also noted that the main statistically significant
changes are observed in the spring and summer seasons. Changes at some stations were reached
from 0,2 to 1,0 °C in ten years. The most consistent and significant trends in temperature
increase were recorded in March and April.

The results of the analysis of the authors' field and office research materials, video and photo,
morphometric characteristics, and meteorological conditions that preceded forming the debris
flow on June 30 in the Shymbulak River basin presents in the paper. Economic activity in the
catchment area of the Shymbulak River basin created unstable conditions that determined
forming the debris flow during rainfall on June 30. It was established, that disturbance of the
soil-vegetation covers during the slope profiling and planning work for ski slopes increases
the probability of forming debris flows in the Shymbulak River basin. A significant share of
the blame for encouraging and permitting the design and construction of ski slopes in the
debris flow hazards areas lies with scientific and government organizations responsible for
environmental protection. Identifying factors and mechanisms of debris-flow forming helps
to solve the problems for debris flow forecasting.

The article identifies the main factors that determine the resistance of pine forests to the effects
of fires. These factors primarily include: the diameter of the stand, the distance to the crowns,
the depth of the roots, the reserves of forest fuels, the amount and height of undergrowth, and
the participation of hardwoods. The article provides an integral assessment of the degree of fire
resistance of pine forests of Kostanay region. The assessment of the degree of fire resistance
is based on the use of a point system by finding the sum of the weight coefficients for the
territory of Kostanay region. Pine forests were selected for the study, on the territory of the
Novonezhinsky, Kalininsky forestry within the Semiozero forestry, as well as the Western
Forestry within the Basaman forestry. The data show that as a result of calculations, most
of the pine forests of the Novonezhinsky forestry of the Semiozerny forestry are assessed as
highly fire-resistant.

This article examines the influence of various natural factors on the formation of landscape
and soil complexes in the Zhaiyk River basin. The key components considered in the study
include soil types, topography, and natural landscapes. The analysis reveals that the soils
of the region range from chestnut and chernozem to sod-podzolic and solonetz soils, which
determine the characteristics of vegetation and agricultural potential. Soil complexes are
largely shaped by topography, water regime, and climatic conditions. Based on cartographic
data obtained from satellite imagery and digital terrain models, an analysis was conducted
to assess the distribution of soils and their relationship with vegetation types, water
bodies, and other natural features. The results of the study reveal important patterns in the
distribution of soil types and assess their role in the region’s ecosystems, providing practical
insights for land resource management, agriculture, and environmental conservation in the
Zhaiyk River basin. Topography, in turn, affects water exchange and erosion processes,
which significantly influence soil types and their distribution. Special attention is given to
identifying the interrelationships between soils, topography, and vegetation, as well as the
role of these factors in the formation of sustainable ecosystems. The findings confirm that
the complex interaction of topographical and soil features influences the distribution of
landscape zones, which is crucial for planning agricultural activities and nature conservation.
The Impact of Implementing AI-Generated Audio Transcriptions on English Majors’ Cognitive Load
Authors: Nguyen Ngoc Ly , Nguyen Thi Phuoc Loc
Published: January 2025

AI has become a daily personal tutoring system to address the needs of English majors, particularly those seeking a revolution in listening methods. Automatic AI-Generated Audio transcriptions (AIGATs) can improve learners' listening comprehension (Cao, Yamashita, & Ishida, 2018); however, there are concerns that if AI transcriptions lack thoroughness, it may negatively affect learners' cognition. Within the confines of this study, we investigate how AIGATs engender a profound impact on 86 English majors’ cognitive load (CogL) and their perspectives towards the applications of AIGATs. The participants were divided into two groups: one was exposed to the listening practice sessions with AIGATs, and the rest with their own transcriptions (PTs). Data is collected through CogL scales on AIGATs and PTs groups, respectively. A semi-structured interview was conducted to examine the AIGATs group’s perspectives. The findings revealed statistically significant differences in the two groups’ CogL test scores. Using AIGATs helps students lower their CogL test scores and enhance their cognitive abilities in handling task complexity. This research provides valuable insights for integrating AI into language education, helping educators create more efficient language instruction methods for English learners in the digital age.

Published: January 2025

In this study, the quality of some pepper species, collected in Ba Ria – Vung Tau, Vietnam in March 2022, was investigated. The content of oleoresin and piperine was evaluated based on the species, size, ripeness, and density of the peppercorn. Piperine content in the peppers was determined by spectrophotometry (UV-Vis) and high-performance liquid chromatography (HPLC). In addition, the study also examined the quality of white pepper. The results showed the Vinh Linh pepper had high oleoresin content (23.72±0.01%, second only to Sri Lankan pepper) but there were no outstanding records in piperine content among all investigated pepper species. For the size parameter, the piperine content on the dry material declined from the smallest peppercorn size of 2.50-4.00 mm (4.94±0.32%) to the largest size > 5 mm (2.66±0.09%). The oleoresin and piperine recovery efficiency of Vinh Linh pepper tended to stop or decrease when entering the ripening stage. Specifically, ripe peppercorns had low oleoresin content (15.92±0.51%). Similarly, from density of 600 to 300 g/L, the lower the density of pepper, the higher the piperine content (3.11±0.09% to 5.04±0.05%) was found. Furthermore, black pepper obtained 2 times higher oleoresin content than white pepper, but the piperine content was lower by many times. This research shredded light on the classification of the Vietnamese pepper for suitable applications in the commercial market.

Published: January 2025

This text addresses the need to transform art education in the Spanish university context, emphasising the opportunity offered by service-learning in art galleries. It is based on the restrictions of education and visual culture in current curricula, as well as the lack of demand from a contemporary society that, nevertheless, values practice and learning with active methodologies. Through an analysis of 1835 art galleries, we seek to identify service-learning experiences that integrate university students with young audiences, promoting a dynamic and interactive educational approach and compared with a reference project of an artistic-social nature. The study is structured based on a literature review, a quantitative data analysis and a qualitative approach to systematise the results, collected in an instrument designed ad hoc. In addition, the importance of cultural and artistic competence in education is emphasised, together with the promotion of cooperation and coexistence in a diverse environment.  The scarce presence of service-learning activities in the framework of the arts has led to the proposal of an educational model that transcends the traditional curriculum and provokes practical and meaningful learning that prepares university students for the challenges of the 21st century.

Authors: Yunta Valbuena Maribel , Merchán Arroyo Sara
Published: January 2025

Currently, excessive exposure to digital screens has generated a negative impact in various social and educational spheres, increasing the prevalence of refractive errors, particularly myopia. According to the World Health Organization's (WHO) meta-analysis in the World Report on Vision (2020), the number of children and adolescents with myopia is expected to increase by 200 million between 2000 and 2050. Technological advances have made the use of electronic devices a daily necessity, and their excessive use among children and adolescents is causing a premature deficit in visual function, as well as affecting physical, social, and cognitive development. Due to the lack of knowledge about visual health and the damage caused by screens, it is necessary to develop new strategies to prevent early-onset myopia. This study, conducted in an educational center in the Community of Madrid, found that 45% of students have never undergone eye examinations, and 44% of teachers recognize early symptoms of myopia in children. Using a mixed-method approach, based on the application of surveys, interviews and direct observation, the aim is to identify variables related to screen use and exposure to prevent their impact on the increase of myopia among Early Childhood and Primary Education students. It provides strategies and educational guidelines to raise awareness and train students, families, and teachers about visual damage and its repercussions on development. This work will help create awareness about the importance of proper visual health and the responsible use of electronic devices.

Authors:   Research Scholar, SJB College of Research Centre, University of Mysore, L. A Sanjay
Published: January 2025

This research has explored the nature of investment strategies by venture capitalists in Bangalore, mainly in terms of deal generation, geographic proximity, monitoring of deals, exit strategy, and evaluation of deals. It is basically to determine which are the prominent factors influencing their investment decisions along with their priorities. The adopted methodology for conducting this research work is exploratory, based on a sample population of 100 venture capitalists identified through convenience sampling. A structured questionnaire was used to collect data, and the responses were analysed on a five-point Likert scale. Multiple regression techniques were applied in SPSS to test the relationships among variables. The results indicate that deal evaluation and exit vehicles are the most important factors, whereas geographic proximity exerts the least influence, thus contesting conventional assumptions. Structured mechanisms of evaluation and robust exit strategies are the only means towards investment success. These findings have theoretical contributions to investment decision-making literature and practical implications toward venture capitalists, but a sample size and focus on a particular region bring about the need to carry out further research to make the generalizability better.

Published: January 2025

- Early and accurate diagnosis of malaria is important for effective treatment and reduction of mortality rates. Traditional microscopy and manual cell counting methods are labor-intensive and prone to errors. This project introduces an innovative solution in the form of an automated cell counting system. The system is designed to efficiently identify and count red blood cells (RBCs), distinguishing between uninfected and malaria-infected cells with high precision. The proposed system will overcome the limitations of conventional methods by automating the counting process, with reduced processing time and minimized human error. The approach promises to deliver faster and more accurate diagnostic reports, which would facilitate early detection and treatment of malaria. The efficiency of the model will be judged based on the precision in the identification and enumeration of cells as well as its capability to provide diagnostic reports with a speed far more superior than that of the manual procedures. Finally, this automatic system will lead to an efficient diagnosis, improved patient care, and a further contribution to the fight against malaria.

A Review on Autologous Platelet-Rich Plasma (Prp) Associated with Split Thickness Skin Grafting (Stsg) in the Treatment of Chronic Non-Healing Ulcers
Authors:   Associate professor & Head clinical preceptor, Krishna Teja Pharmacy College,, Pavithra C.
Published: January 2025

Chronic non-healing ulcers present a significant clinical challenge due to their prolonged healing times and resistance to conventional treatments. Recent advances in regenerative medicine have introduced autologous platelet-rich plasma (PRP) as a promising therapeutic option. PRP, known for its high concentration of growth factors, has been shown to accelerate wound healing by enhancing tissue regeneration and angiogenesis. When combined with split-thickness skin grafting (STSG), PRP offers a synergistic approach to the management of chronic ulcers. This review evaluates the efficacy of PRP in conjunction with STSG in the treatment of chronic non-healing ulcers, drawing on recent clinical studies, case reports, and trials. The review highlights the biological mechanisms of PRP in wound healing, the procedural considerations in integrating PRP with STSG, and the clinical outcomes associated with this combined approach. Findings suggest that the use of autologous PRP alongside STSG significantly improves graft acceptance, reduces healing time, and promotes faster epithelialization, ultimately leading to better wound closure and patient recovery. However, the need for standardized protocols and further large-scale studies is emphasized to establish consistent guidelines for its use in clinical practice. This review aims to provide healthcare professionals with an updated perspective on this evolving treatment modality for chronic non-healing ulcers.

KEY WORDS: Chronic ulcers, Platelet-rich plasma, Split-thickness skin grafting, Regenerative medicine, Wound healing, Tissue regeneration.

This study focuses on the effects of the perception of physical elements on the perception of emotions and communication with cartoons of people of different ages and cultures classified by nationality and age range. The objectives of this research were: 1) to analyze the physical characteristics that affect emotional perception and communication; 2) to analyze and compare the relationship between the physical elements of an image comprising cartoons, emotional perception, and communication. This was a quantitative and qualitative study with a population and sample of 300 volunteers from three nationalities and three age groups: Thai, Japanese, and American. The tools used in this study were questionnaires and interviews using a 5-level estimation scale. Data analysis utilized statistics for comparative analysis and determined the mean and standard deviation. The results showed that the emotional and sensory perception levels were very high, with a mean of 4.06 and standard deviations of 0.89. Emotional characteristics create emotional perception and strengthen emotional awareness, which are at a high level, with a mean of 3.95 and a standard deviation of 0.95. Characters and scenes create emotional perception; deformed character ratios create emotional and sensory perception; natural scenes generate emotional and sensory perception; 2D shapes can generate emotional and sensory perception; depth of field generates emotional and sensory perception; and light and shadow generate moderate emotional and sensory perception, with a mean of 3.80 and standard deviations of 0.97. The scene produced a low level of emotional and sensory perception, with a mean of 3.66 and standard deviations of 1.07. Large characters generate very little emotional perception, with a mean of 3.52 and a standard deviation of 1.04. However, the analysis also shows that a p<0.05 value is considered statistically significant. Similarly, the interviews showed that the artistic elements were at the highest level of perception generation, and they were also able to analyze and compare physical characteristics according to the set objectives.

The Nariinsukhait deposit is the largest Jurassic coal deposit in southern Mongolia. A total of 90 core samples were obtained from a 493.1 m deep borehole in the central part of the deposit and tested for proximate analysis and caking properties, while 29 composite samples were analyzed for maceral composition and random vitrinite reflectance. The thick seam V stands out for its better quality compared to the upper seams, with an average ash content of 12.4% (ad), total sulfur of 0.5% (ad), volatile matter of 36.7% (daf), inherent moisture of 0.6% (ad), calorific value of 6,600 kcal/kg (ar), and a G index of 84 (ad). Seam V is characterized by higher inertinite content (32.2 vol.%), and lower vitrinite (58.0 vol.%) and mineral matter contents (6.7 vol.%) relative to the upper seams. Additionally, this seam has a higher rank, with random vitrinite reflectance (Rrand) of 0.77%, compared to 0.65-0.70% for the upper seams. According to MNS 6457:2023 standards, seam V is classified as “1/3 coking coal”, while the upper seams are classified as “high volatile gas coal”. Based on TPI, GI and A/I indices, seam V was deposited in oxic, ombrotrophic mire, whereas the upper seams were formed in mesotrophic and rheotrophic mires with high water tables and less oxic conditions. Due to these depositional environments, seam V exhibits higher inertinite, lower ash, and lower sulfur contents than the upper seams. The rank of the Nariinsukhait coals is comparable to that of Jurassic coals in central Mongolia, while the maceral composition and coal quality of the upper seams align with those of Jurassic coals. Seam V is distinct in its high inertinite and low total sulfur contents. The Nariinsukhait coal is primarily semi-soft coking coal (2/3 of total coal resources) and is also suitable as high-quality PCI coal. Further detailed studies are recommended to evaluate its potential for liquefaction and as a coking coal blend.

Social media sites like Instagram, Facebook, and Twitter frequently give individuals access to the breathtaking natural features of other places through visuall y appealing images that travellers and influencers share. The study aimed to explore how social media influences people's views about ecotourism. This research study was conducted using a quantitative research design. Using a survey approach, the data was gathered from (n=313) respondents based on purpose sampling who were active social media users. The sample consisted of males and females from Rawalpindi and Islamabad, Pakistan. For data collection, a self-design questionnaire consisted of three parts, i.e., demographic information of the respondents, social media use and eco-tourism based on the Likert scale. The data collection tool was designed on Google Forms and was distributed through Facebook, WhatsApp and Instagram. The study findings showed that social media is an effective instrument for public education, awareness-building, and conservation activities. It helps to sell and promote ecotourism experiences and destinations, empowers local communities, and shifts consumer behaviour towards sustainability. The research concluded that ecotourism when adeptly managed via social media with a focus on social, cultural, and environmental sustainability, will shape its outcomes. This sector has the capacity to utilize social media's transformative power to foster a more resilient and inclusive future for our planet and its inhabitants through collaborative efforts and informed decision-making.

A aderência ao tratamento é essencial no tratamento medicamentoso de doenças crônicas como a hipertensão arterial e o diabetes, com o objetivo de controlar e prevenir ou retardar o surgimento de complicações. No entanto, a avaliação da concordância as orientações que aderem ao tratamento medicamentoso precisa ser examinada em  âmbitos globais, específicos e individuais, considerando que sua compreensão está necessariamente associada ao estudo sistemático dos mesmos processos que devem guiar a análise do processo saúde-doença: os processos estruturais da sociedade, que constituem o âmbito global; os padrões de reprodução social (produção e consumo) das diferentes classes e frações de classes, que constituem o âmbito específico; e a compreensão abrangente de fenômenos biológicos e comportamentais que compõem os padrões característicos de saúde desses grupos e de seus indivíduos, que constituem o âmbito individual. O objetivo deste trabalho é avaliar a adesão ao tratamento medicamentoso em pacientes diabéticos e hipertensos da unidade básica de saúde Campo Belo, em Gurupi- To, analisando também o perfil socioeconômico, comportamental e de saúde destes pacientes, estabelecendo a relação entre estes fatores com a adesão ao tratamento medicamentoso, com o propósito de promover a melhor adesão ao tratamento e aumentar a efetividade terapêutica.

Este artigo apresenta uma análise das alterações nas propriedades mecânicas de argamassas de cimento e areia com a adição de açúcar refinado, quando submetidas a altas temperaturas. O objetivo do estudo é compreender, sob uma perspectiva científica, o uso empírico amplamente difundido da adição de açúcar às argamassas de cimento para retardar o tempo de pega e aumentar a resistência mecânica a temperaturas elevadas. Para alcançar esse objetivo, foram confeccionados corpos de prova cilíndricos e prismáticos, utilizados em ensaios mecânicos e análises de propriedades em amostras com e sem adição de açúcar. Estas amostras foram submetidas a diferentes temperaturas, variando entre 25°C e 750°C, por períodos previamente determinados. Adicionalmente, foram realizados ensaios no estado fresco da argamassa, incluindo a determinação dos tempos de pega, consistência e densidade. A análise dos resultados demonstrou que, para o traço adotado, o aditivo proporcionou melhorias significativas nas resistências mecânicas até 300°C. Acima de 450°C, o aditivo não apresentou impactos significativos nas propriedades mecânicas da argamassa. Observou-se ainda que a adição de açúcar retardou o tempo de pega, aumentou a fluidez da mistura, reduziu a absorção de água e a porosidade, além de incrementar a densidade da argamassa.
