The coronavirus disease 2019 pandemic impacts all aspects of life.While the focus is biased towards the direct health and economic impacts associated with the pandemic, there is increasing concern and recognition that the current crisis has had differential impacts and that those who are vulnerable, are more likely to bear the brunt of the unintended consequences of the lockdown and other measures to curb the spread of the virus.The COVID-19 pandemic has been foregrounded as a 'perfect...

The transport sector is a prominent source of increasing fuel consumption and greenhouse gas (GHG) emissions. Electric vehicle (EV) is deemed an appealing solution for those problems. However, due to the variation in charging demands, the high penetration of electric vehicles may cause different problems to the distribution network and its reliability. Therefore, several approaches are employed to predict the EVs charging demand and avoid the corresponding challenges. This paper compares the...

Africa struggles with the double burden of disease, bearing the highest disease burden in the world and also having the most severe health workforce shortage. Only four countries on the continent meet the WHO-recommended density of 4.45 health workers per 1000 people. This physician shortage has been attributed to a variety of factors including shortfalls in medical education and medical schools' capacities. This commentary aims to reveal the gap and 'underrated' problem of inadequate...

Fogo volcano belongs to the Cape Verde Archipelago, and it is one of the most active volcanoes in the Atlantic Ocean, which most recent eruption occurred from November 2014 to February 2015. We analyzed ambient seismic noise recordings of three different networks deployed in the island, totalizing 14 seismic stations, to derive a crustal 3D shear-wave crustal velocity model of the volcano. Through the phase cross-correlation technique followed by a time-domain phase weighted stack, we were...

The prevalence of dementia in Blacks/African Americans (AAs) is almost twice that of Whites. Inequities in access to health care, socioeconomic conditions, and diabetes contribute to this disparity. Poorly controlled diabetes, which is more prevalent in Blacks/AAs, causes microvascular disease and neurodegeneration and increases dementia risk. Improving glycemic control, therefore, may prevent cognitive decline. To address this issue, we developed Diabetes Regulation for Eyesight and Memory...

Global agricultural production, in particular, is of increasing concern to the major international organizations in charge of nutrition. The rising demand for food globally due to unprecedented population growth has led to food insecurity in some populated regions such as Africa. Another contributing factor to global food insecurity is climate change and its variability. World and African agricultural production in particular are of increasing concern to the major international organizations...

This paper aims to test econometrically to analysis climate change on food security and other which includes economic growth, population growth and agriculture sector. This paper employed data for the period 1971–2020 from open data bank from (WDI) World development indicator and analyzed this data using Vector Autoregressive Approach (VAR), Granger Causality Approach, Autoregressive Distributed lag mode approach (ARDL) and Error Correction Approach (ECM). Empirical evidence displays, food...

The study was conducted to determine effectiveness of a training intervention in increasing use of misoprostol in management of incomplete abortions.A quasi-experimental study with training intervention on use of misoprostol in treatment of incomplete abortion.Five secondary-level public hospitals in Malawi, one in urban and four in semiurban settings. Three intervention and two control sites.Records of women treated for first-trimester incomplete abortion from March to May 2020 (baseline)...

<span lang="EN-US">The study of learners’ conceptions of geological concepts has been the subject of several studies in the field of earth science didactics. The majority of these studies show that learners have misconceptions that can be an obstacle to learning Earth sciences. The present work aimed to identify the views of second year undergraduate students on plate tectonics to identify some of the barriers to teaching this unifying scientific theory across the different disciplines...

Wars, whether of full-scale invasion and military aggression or on a lower scale of intensity, destroy educational infrastructure and aspirations. But during war, education can also hold out the possibility for alternatives. Using South Africa in the 1980s as a case of low-intensity war, this article shows how parts of the system became militarised but also how an alternative vision was created through and in education. Nationalism, militarism and gendered identities romanticising war and...

Mantle xenoliths from a Pliocene (∼2 Ma) pyroclastic cone of the Jabal Eghei Volcanic Complex (south Libya) are studied for unravelling depletion-, deformation- and metasomatic events within this part of the Saharan Metacraton. The xenoliths are fertile Cpx-rich spinel lherzolites texturally distinguished into protogranular (hereafter: undeformed – UX) and porphyroclastic/equigranular (deformed – DX) types. The extent of depletion is estimated at 5–10% (olivine-spinel compositions) and 3–13%...

In the present work, we investigated the bio-uptake of 4 MTE (Ni, Cd, Pb, Zn) in the thalli of some species of lichens near a road crossing the Dar-Chichou forest (NE- Tunisia). In the absence of previous studies on the lichenic heritage of this forest, the objectives of this work are. first of all to identify for the first time the lichen species present in the forest, to determine the impact of this road pollution on certain physiological parameters of these pioneer species, such as the...

To investigate inequalities of health insurance coverage (outcome) at subnational level, and the effects of education and poverty on the outcome.Secondary analysis of Demographic and Health Surveys. The outcome variable was health insurance ownership.The Democratic Republic of the Congo.Women aged 15-49 years (n=18 827).Findings indicated significant spatial variations of the health insurance ownership which ranged from 1.2% in Bandundu and Kasaï Oriental to 15.5% in Kinshasa the Capital...

Species distribution modelling is gaining popularity due to significant habitat shifts in many plant and animal species caused by climate change. This issue is particularly pressing for species that provide significant ecosystem goods and services. A prominent case is the valuable African rosewood tree (Pterocarpus erinaceus) that is threatened in sub-Saharan Africa, while its present distribution, habitat requirements and the impact of climate change are not fully understood. This native...

Floods have a terrible impact on people's lives and property all around the world. In this study, we evaluated the modeling capabilities of two Machine Learning (ML) approaches such as Naive Bayes Tree (NBT) and Naive Bayes (NB) and four Multi-Criteria Decision-Making (MCDM) analysis techniques MABAC (multi-attributive border approximation area comparison), TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), VIKOR (Vise Kriterijumska Optimizacijaik Ompromisno Resenje),...

Autosomal recessive non-syndromic hearing loss (ARNSHL) is very heterogeneous at the molecular level with ˃75 genes being involved. In this study, whole exome sequencing (WES) was applied to investigate the molecular defect in an Egyptian male child with sensorineural hearing loss. The patient also exhibited mild neurological and overt orodental abnormalities. Novel nonsense mutation (p.Arg187*) in the ESRRB gene has been detected resulting in early protein truncation. ESRRB gene is coding...
