Cerebral venous thrombosis (CVT) are underdiagnosed in sub-saharan Africa where publications are uncommon. Our study aim was to describe the CVT diagnostic and therapeutic features through a senegalese case series. A monocentric retrospective and prospective study was conducted at the adult Neurology department of Fann Teaching Hospital in Dakar (Senegal), between January 01, 2013 and April 30, 2020. It had included all CVT cases diagnosed by neurovascular imaging. Seventy CVT cases were...

Nakanbé River watershed in the West Africa Sahel (WAS). This study aims to better understand the hydrological behavior of WAS watersheds, which experienced Sahelian hydrological paradoxes (SHP). Budyko framework was employed to evaluate the impact of climate change, environmental change and climate-environment interaction on surface runoff change in seven nested watersheds (38 – 21,178 km2) over the period 1965–2018. Based on time-series stationarity statistical tests, the study period was...

This study has examined traditional coping systems, emerging adaptation strategies and barriers to the adoption of these strategies. Structured questionnaires on coping and adaptation strategies were conducted among Nyangatom households, expounded by focus group discussions and key informant interviews. Correlations between times series (1987–2016) on rainfall, temperature and the local perceptions on CC were examined. The time series analysis confirmed pastoralists' perception that the...

A suite of Neoproterozoic island arc volcanic and plutonic rocks are exposed in the Hamash area of the south Eastern Desert of Egypt. The volcanic assemblage includes metabasalt, a group of andesites with subordinate basalts (the Hamash Volcanics), and felsic volcanic porphyry. The plutonic rocks include a diorite-tonalite series, fine-grained granite, and granite porphyry. The volcanic rocks are generally sub-alkaline and feature a strong depletion in Nb and Ta. The metabasalt belongs to...

Solar prediction models are essential in developing countries such as South Africa as most meteorological stations are unable to consistently measure this quantity. Quantification of solar radiation is of great significance for the adoption and application of renewable energy systems. Machine learning models are infamous for their high prediction capacity and low input requirements. This study's foremost intention was to investigate the efficacy of using the most widespread machine learning...

Abstract Education plays a key role in socio-economic development. Transport to school is the main obstacle for students in Sub Saharan African to acquire better educational achievement. In Tanzania, urban roads are heavily congested, and long traffic jams hinder early arrival to schools whereas in rural areas schools are remotely located. Electrically assisted bicycle, simply e-bicycle, presents a promising alternative means of individual commuting. However, there is a lack of knowledge...

Statistical models predict that the world's population will reach 8.5 billion by the end of 2030. This represents a real threat to our food security and puts the current food production system under pressure. Efficient use of Earth's natural resources is the only solution to facing future challenges such as global hunger. The implementation of precision agriculture using new technologies such as artificial intelligence, big data, IoT and remote sensing is the first step towards this goal. In...

Introduction: The promotion and maintenance of a healthy lifestyle remains a persistent challenge globally. As a result, the deleterious effects of chronic diseases are escalating globally. But, nevertheless healthy diet and physical activity practices are not yet assessed among university students in Ethiopia. Therefore, this study was aimed at assessing healthy diet and physical activity among Mekelle university students from September 2019 to June 2020. Methods: We used cross-sectional...

Aims Somaliland is a de facto state in the horn of Africa. It unilaterally declared independence from rest of Somalia in 1991. Medical education in Somaliland started in the year 2000. Aim of the study is to explore the feasibility of teaching program for the country by its future potential psychiatry educators. The initiative started in 2019 to seek trainees with interest in academic psychiatry and support them with medical education skills. This is intended to prepare them for leading...

This work investigates Mesoproterozoic volcanic rocks of the Haiber Flats, Barby, Welverdiend and Kairab Formations, and associated intrusive rocks in the Konkiep Terrane. Various correlations have been made in the past and recent dating work yields contrasting ages. U–Pb dating of zircons is applied in combination with Sm–Nd and Lu–Hf isotopes to determine the age, assess correlation and ascertain the much-debated tectonic setting. Ion probe U–Pb zircon dating yields ages of 1218 ± 5 Ma,...

In this paper, the water resources system in Qena governorate was proposed by studying the natural and hydrogeological conditions of the governorate, including its location, groundwater, climate and rain. Also Studying the Social and economic conditions of the study area including its population, crops, drinking water and etc. Through the water balance model and a Water Shortage Quality Index on 3 scenarios: the base case scenario in 2018, the realistic scenario in 2050 without any...

Abstract Disregarding research not published in English may pose a risk to finding solutions for urgent global concerns, such as biodiversity loss, or climate change. To assess the extent of this ‘missing voice’, we compared the representation of 22 languages in scientific publications on climate change in Africa, indexed by widely used databases. Between 87 % and 95 % of publications were in English, with a small, but noteworthy, number in languages of the former European colonisers of...

Complementary and alternative medicine (CAM) is commonly used, but many physicians have limited knowledge of CAM despite its widespread use. Therefore, this study sought to assess the knowledge, attitude, and practice of medical students on complementary and alternative medicine in the management of COVID-19.A descriptive cross-sectional study was conducted among 150 medical students from three Federal Universities in South West, Nigeria. A self-administered semi-structured online Google...

In this essay, I explore the asymmetry of value and power inherent in African communitarian philosophy's assumptions about personhood and the implications of these assumptions for disabled people's access to healthcare in the COVID-19 pandemic era. While African communitarian philosophy forms the fulcrum on which people in an African community thrive and survive, it is also essentially laden with an ontology of exclusion that prioritizes some people as persons over other people who are cast...

It is essential to understand the relationship between pubertal rites and the goals of socioeconomic insertion of children to school. Formal education promotes girls' rights and contributes to the creation of an egalitarian society. It empowers women to make better informed life choices. This survey used ethnographic data from the pubertal rites "Famian Bla" in Baoule Iffou County and "Yikee" in Toura County, Cote d'Ivoire as a reference point to examine the law of obligatory education of...
