Water scarcity is a severe problem in Tunisia, particularly in the northern region crossed by the Medjerda River, where groundwater is a conjoint water resource that is increasingly exploited. The aim of this study is to delineate the groundwater potential zones (GWPZs) in the Lower Valley of the Medjerda basin by using single benchmark machine learning models based on artificial neural network (ANN), random forest (RF), and support vector regression (SVR), and by developing a novel hybrid...

This study examined the prevalence of addictive Internet behavior and its links with mental health among pre-service teachers in Ghana. A descriptive, correlational design was employed with 405 pre-service teachers from colleges of education and a public university in Ghana participating in this study. The sample completed a sociodemographic survey about loneliness, life satisfaction, depression, self-esteem, and the Internet addiction scales (abridged form). The results revealed that there...

The article is devoted to the agricultural technology of growing mallow (Malva l.) in the field. Growing mallow is a simple process. Regular moderate watering, loosening the soil and weeding, timely removal of wilted flowers are mandatory requirements in caring for mallow. KEY WORDS: roots, buds, leaves, sprouts, seedlings, pests, fertilizers, leaves.

ABSTRACTTailings dam is the main heavy metal pollution source in mining areas. In this study, the concentration of heavy metals in soil and water from upstream and downstream of the tailings dam was analyzed. The concentration of As, Cd, Cu, Ni, Pb, and W in tailings soil exceeded the standard value but Hg and Zn in the tailings soil were far below the standard. Average concentrations of As, Pb, and W in soil samples were above the upstream reference soil. The level of As and Pb decreases,...

Most of research conducted on Learner-Centered Pedagogy (LCP) in sub-Saharan region recommend further exploration of its implementation. This study sought to look into it with particular interest in learner-centred application at University of Rwandan - College of Education.The study adopted a mixed method approach with a sample size of 278 teacher educators and student teachers.The findings revealed teachers’ positive perceptions of learner-centred pedagogy with a grand mean of 3.70 and...

Purpose: The significance of school environmental factors to girls’ education remains central because they have tremendous influence in the quality of teaching and learning of pupils as well as the extent of attention they pay to lessons when in classrooms. This suggests that schools that fail to provide a conducive atmosphere for teaching and learning may hardly achieve the best in their pupils especially in the area of academic performance. This scenario continues to be among the reasons...

Mosquito-borne pathogens are transmitted mainly during blood feeding by infective female mosquito vectors. Blood meals’ digestion stages reveal necessary entomological information for retrospective assessment and future plan for vector control. This study was done to assess the blood digestion stages of Anopheles gambiae and Culex quinquefasciatus mosquitoes and their relationships with climatic conditions in school dormitories in Egor, Oredo and Ikpoba Okha Local Government Areas (LGAs) of...

One of the most important concerns affecting humanity today is climate change that has led to increased frequency of natural disasters that threaten social and economic stability to populations. Zambia’s vulnerability to the threat of disasters remains high because the country still lacks an effective Early Warning System (EWS). This study recognises the need to evaluate various Machine Learning (ML) algorithms, that have been successfully implemented in disaster prediction, in order to...

In his seminal and highly influential work Pedagogy of the Oppressed (1970), the Brazilian scholar Paulo Freire refers to education as “becoming an act of depositing, in which the students are the depositories and the teacher is the depositor.” Freire strongly criticizes what he calls “the banking model” of education, whether in schools colleges or universities. This model of pedagogy is prevalent and dominant in many countries of the world, and in Algeria–the country under focus in this...

Agricultural production can achieve sustainability by appropriately applying agricultural mechanization, especially in developing countries where smallholding farmers lack sufficient agricultural machinery for their farming operations. This paper aimed to study the extent to which small-, medium-, and large-scale farms in the Delta of Egypt use agricultural mechanization in their wheat crop farming operations. K-means clustering was used to aggregate and analyze the scenarios implemented by...

The study investigated Literature-in-English teachers' assessment literacy and practices in Nigeria. The mixed method design was adopted, and the participants were 47 secondary school teachers selected from 47 schools in the Ibadan metropolis, Oyo, State, Nigeria. Teachers’ Assessment Literacy Test (r=.78), Class Assessment Checklist, and Interview Guide were used to collect quantitative and qualitative data. The quantitative data were analyzed using the descriptive statistics, and the...

This study was carried out in order to determine the initial distribution of Mediterranean fruit fly Ceratitis capitata Wiedemann (1824) (Diptera, Tephrididae) in Algeria, the area now occupied and assess the role of climate change in determining its current distribution. The various surveys and trapping of adults indicate that in addition to the coastal, sub-coastal and Argan regions, this fly is also present in oases. It is reported in all the traditional oases where fruit trees are...

Background: Vaccine hesitancy is a global problem. This phenomenon is context specific and has a changing nature. It may be difficult to address vaccine hesitancy with a one-size-fits-all approach. The causes of vaccine hesitancy should thus be known in order to properly address this phenomenon. The aim of this study was to explore vaccine hesitancy in students attending a South African university. Methodology: The study was performed via an electronic survey, namely the Student Vaccine...

The Paris Agreement has highlighted the worldwide significance of adaptation. Many investors are considering the effects of climate change and resource scarcity when making decisions. Even while the whole amount of the environmental harm caused by climate change is yet unknown, recent scientific evidence is more frightening, and many governments are taking substantial measures to avert a calamity. The financial innovations and mechanisms created to ease the transition to a low-carbon economy...
