<p>In a near future, the Sahara and Sahelian regions could experience more rainfall than today as a result of climate change. Wetter conditions in the hottest and driest place of the planet today raise the question of whether the near future might hold in store environmental transformations, particularly in view of the growing human-induced climate, land-use and land-cover changes. Reflecting an enhancement of the global hydrological cycle under warmer conditions, some...

<p>The Main Ethiopian Rift (MER) is the northern portion of the East African Rift System and separates the Eastern and Western plateaus of Ethiopia. The recent volcanic and tectonic activity is largely focused within the rift basin along a 20 km wide zone on the rift floor. Large silicic volcanic complexes are aligned along this central rift axis but their eruptive histories are not well constrained.</p><p>The Bora-Baricha-Tullu Moye (BBTM) volcanic...

<p>Sand and Dust Storms (SDS) are extreme meteorological phenomena associated with high amounts of atmospheric mineral dust. SDS are an essential element of the Earth’s natural biogeochemical cycles but are also partly caused by human factors including anthropogenic climate change and unsustainable land and water management; in turn, SDS contribute to climate change and air pollution. SDS have become a serious global concern in recent decades due to their...

This paper examines the determinants of teacher’s job satisfaction and the implications on their job commitment. The study concentrated on pre-tertiary school teachers in the Greater Accra region, Ghana. Quantitative survey approach based on positivist philosophies research design was adopted in gathering data. Over 96% (676) participated fully in answering questionnaire from a sampling frame of 700. For the analysis of data, a number of descriptive statistical tests and in combination of...

<p>The Danakil depression in the Afar region of Ethiopia marks the change from subaerial continental rifting to seafloor spreading further north in the Red Sea <sup>[1]</sup>. Extension and volcanism in this incipient spreading centre is localised to the ~70-km-long, 20-km-wide active Erta Ale volcanic segment (EAVS), with multiple volcanic centres consisting of a combination of fissures, shield volcanoes and stratovolcanoes...

Globally, there is a growing concern over antimicrobial resistance (AMR) which is currently estimated to account for more than 700,000 deaths per year worldwide. AMR undermines the management of infectious diseases in general especially in pregnancy where significant bacteriuria continues to be a serious cause of maternal and perinatal morbidity and mortality. We therefore aimed to determine the prevalence of AMR and the associated factors among pregnant women with urinary tract infections...

<p>Under- and malnutrition – particularly in the first years of life – can severely impact the physical and mental development of a child. This can have lasting consequences for the child’s future education, health and wellbeing outcomes. At the same time, climate change is expected to intensify the frequency and severity of droughts in many regions of the world, exacerbating concerns about food security and nutrition. Using repeated...

<p>This paper aims to analyze the agronomic drought in a highly anthropogenic  semi-arid region, North Africa. In the context of the Mediterranean climate, characterized by frequent droughts, North Africa is particularly affected. Indeed, in addition to this climatic aspect, it is one of the areas most affected by water scarcity in the world. Thus, understanding and describing agronomic drought is essential. The proposed study is based on remote sensing data from...

Diabetes mellitus is characterized by major changes in the coagulation and fibrinolytic system. The study was aimed at assessing the degree of changes in the coagulation and fibrinolytic system in patients with type 2 diabetes mellitus in North-central Nigeria. This was a hospital based comparative Cross-sectional study involving 78 type 2 diabetics and 78 healthy controls. Full blood count was performed using Sysmex XP 300 according to manufacturer’s instructions. Prothrombin time was...

(1) Background: Nearly one out of ten Ghanaian female adolescents aged 15–19 has experienced childbearing in urban settlements compared to twice this number in the rural populations due to unintended pregnancies. This study assessed the linkages between knowledge, attitudes, and use of contraceptives and adolescent pregnancy in one of the highly affected Municipalities (i.e., Komenda-Edina-Eguafo Abrem [KEEA]) in Ghana. (2) Methods: Employing a facility-based sampling method, 378 female...

Childhood obesity is a major public health concern around the globe as it is associated with adverse consequences such as psychological problems, lower educational attainment, and a high risk of health challenges later in life. The study investigated the prevalence of obesity and its socio-psychological effects on primary school children in the Cape Coast Metropolis, Ghana. Interview schedule and interview guide were used to collect primary data from 317 pupils and 24 teachers respectively...

This study explores collaborative and individual computer-assisted prosody training (CAPT) through a quasi-experimental design. Eighteen adult Algerian EFL learners were recruited and randomly assigned into a control group receiving no treatment and two experimental groups, a collaborative CAPT group where the participants practiced in pairs, and an individual CAPT group where the participants practiced on their own. The two experimental groups enrolled in six CAPT sessions using Tell Me...

<p>East Africa has high rates of soil erosion which negatively impact agricultural yields. Climate projections suggest that rainfall intensity will increase in East Africa, which may increase soil erosion. Soil erosion estimates require information on rainfall erosivity, which is calculated using sub-daily storm characteristics that are known to be biased in traditional parameterized convection climate models. Convection-permitting climate models, which are run at higher...

Clean cooking interventions to reduce air pollution exposure from burning biomass for daily cooking and heating needs have the potential to reduce a large burden of disease globally.The objective of this study is to evaluate the air pollution exposure impacts of a fan-assisted efficient biomass-burning cookstove and a liquefied petroleum gas (LPG) stove intervention in rural Ghana.We randomized 1414 households in rural Ghana with pregnant mothers into a control arm (N = 526) or one of two...

Objective - Worldwide, higher education is critical for the social economic development of the society. However African countries such as South Africa, fail to produce quality graduates capable of facing the challenges of the fourth industrial revolution. Considering the increasingly competitive and dynamic environment, African countries can no longer ignore the needs and factors required to enhance student performance. The aim of this research is to examine the influence of student...

Background: Dysmenorrhea remains one of the common gynaecological conditions among women of reproductive age. With varying severity, it can be associated with morbidities that affect the quality of life. Among students, dysmenorrhea leads to school absenteeism which may ultimately affect school performance. Objectives: To determine the prevalence of dysmenorrhea among undergraduates as well as the incidence of school absenteeism in women with dysmenorrhea. Methods: A questionnaire-based...

<p>The north-central region of Algeria has been characterized by a swarm-type seismicity, after the strong Mw6.8 Boumerdès earthquake of May 21, 2003, culminating with the earthquake that occurred on July 17, 2013 of magnitude Mw=5. A magnetotelluric station was installed on December 2014 in the Medea region, 60 km south of the capital Algiers. We measured the five components of the telluric and magnetic field with a sampling frequency of 15 Hz. The seismic...
